Description
本發明是關於一種使用於空調裝置之冷媒循環用配管等各種配管的撓性管，特別是關於一種技術，在該技術中，不僅借助熔接固定之強度，而且也加入其他強度要素，使得與配管之連接不會只受到熔接技術影響的情況下，保持足夠強固之強度。The present invention relates to a flexible pipe used for various pipes such as a refrigerant circulation pipe of an air-conditioning apparatus, and more particularly to a technique in which not only the strength of welding fixation but also other strength elements are added to the piping. The connection will not be strong enough to be strong enough to be affected by the fusion technique.
過去，作為此種撓性管，已知有如第4圖及第5圖所示之撓性管。亦即，第4圖之撓性管1a將外周全面以編織線3a覆蓋之波紋軟管2a及該編織線之端部、銅管4a之相向端部與覆蓋編織線3a之端部之外周的環狀物5a之端部熔接固定在一起以產生連接。第5圖之撓性管1b將外周全面以編織線3b覆蓋之波紋軟管2b及該編織線之端部、銅管4b之形成擴張狀之相向端部與覆蓋編織線3b之端部之外周的環狀物5b之端部熔接固定在一起以產生連接。In the past, as such a flexible pipe, a flexible pipe as shown in Figs. 4 and 5 is known. That is, the flexible tube 1a of Fig. 4 has the outer circumference of the corrugated hose 2a covered with the braided wire 3a and the end portion of the braided wire, the opposite end portions of the copper pipe 4a, and the outer periphery of the end portion covering the braided wire 3a. The ends of the ring 5a are welded together to form a joint. The flexible tube 1b of Fig. 5 has a corrugated hose 2b covered with a braided wire 3b on the outer circumference, an end portion of the braided wire, an opposite end portion of the copper tube 4b which is formed in an expanded shape, and an outer periphery of the end portion covering the braided wire 3b. The ends of the loops 5b are welded together to create a joint.
然而，第4圖及第5圖之兩撓性管1a,1b皆為強度僅借助熔接的構造。因此，連接之強度與熔接技術如何有關，當熔接技術人員之熔接技術拙劣時，強度變弱，波紋軟管2a,2b與銅管4a,4b、環狀物5a,5b之連接變得不充分，會有製品品質降了下來或使用後成為事故發生原因的問題。又，當以焊接材料熔接時，如環狀物5a與銅管4a之段差部或環狀物5b與銅管4b之段差部以塗黑部位來表示時所 顯示出的情況，必須使用並填入大量焊接材料(例如銀焊料)，所以，也會有變成昂貴製品的問題。However, the two flexible tubes 1a, 1b of Figs. 4 and 5 are of a construction in which the strength is only by welding. Therefore, the strength of the connection is related to the welding technology. When the welding technique of the welding technician is poor, the strength is weak, and the connection between the corrugated hoses 2a, 2b and the copper tubes 4a, 4b and the rings 5a, 5b becomes insufficient. There will be problems with the quality of the product being lowered or the cause of the accident after use. Further, when the welding material is welded, if the stepped portion of the ring 5a and the copper pipe 4a or the stepped portion of the ring 5b and the copper pipe 4b is indicated by the blackened portion, In the case shown, a large amount of solder material (for example, silver solder) must be used and filled, so there is also a problem of becoming an expensive product.
此外，曾針對本發明進行先前技術之調查，其中包括特開2005-201412號公報(專利文獻1)，此專利文獻1揭示，將金屬製波紋管與覆蓋此金屬製波紋管之管狀金屬製編織體接合在管套上，構成振動吸收管，可說是與前述第4圖之撓性管1a近似的技術。不過，在此所揭示之振動吸收管亦僅借助熔接固定來保持強度，所以，如前所述，不能說其強度很強。Further, a prior art investigation has been conducted in accordance with the present invention, which includes Japanese Laid-Open Patent Publication No. 2005-201412 (Patent Document 1), which discloses a metal bellows and a tubular metal braid covering the metal bellows. The body is joined to the sleeve to form a vibration absorbing tube, and it can be said that it is similar to the flexible tube 1a of Fig. 4 described above. However, the vibration absorbing tube disclosed herein is also held only by welding to maintain strength, so as described above, it cannot be said that the strength is strong.
[專利文獻1]特開2005-201412號公報[Patent Document 1] JP-A-2005-201412
因此，本發明之目的在提供一種撓性管，其可解決上述習知之發明所具有的問題點，不會僅借助於熔接固定來保持充分之強度。SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a flexible tube which solves the problems of the above-described conventional invention and which does not maintain sufficient strength by means of welding fixation.
為了解決上述課題，申請專利範圍第1項之發明為一種撓性管，包括外周近乎全面以編織線覆蓋的波紋軟管、與此波紋軟管之至少其中一端部熔接固定而產生連接的銅管及覆蓋並嵌入上述波紋軟管與編織線之連接側端部之外周的環狀物，其特徵在於：上述銅管之連接側端部形成為擴徑部，此擴徑部之先端熔接固定於波紋軟管而產生連接，並且，上述環狀物之銅管側端部以覆蓋擴徑部之外周的狀態形成為縮徑部，此縮徑部之先端以可沿著軸方向嚙合於上述擴徑部之狀態熔接固定於上述銅管而產生連接。In order to solve the above problems, the invention of claim 1 is a flexible pipe comprising a corrugated hose which is almost entirely covered with a braided wire at the periphery, and a copper pipe which is welded and fixed to at least one end portion of the corrugated hose to be connected thereto. And an annular body covering and surrounding the outer periphery of the connecting end portion of the corrugated hose and the braided wire, wherein the connecting end portion of the copper pipe is formed as an enlarged diameter portion, and the leading end of the enlarged diameter portion is welded and fixed to The corrugated hose is connected to each other, and the copper tube side end portion of the annular body is formed as a reduced diameter portion in a state of covering the outer circumference of the enlarged diameter portion, and the leading end of the reduced diameter portion is engageable in the axial direction at the expansion The state of the diameter portion is welded and fixed to the copper tube to cause connection.
申請專利範圍第2項之發明如申請專利範圍第1項之撓性管，其中，銅管之擴徑部之最大外徑與波紋軟管之外徑幾乎相等。The invention of claim 2 is the flexible pipe of claim 1, wherein the outer diameter of the enlarged diameter portion of the copper pipe is substantially equal to the outer diameter of the corrugated hose.
申請專利範圍第3項之發明如申請專利範圍第1或2項之撓性管，其中，環狀物之縮徑部之最小外徑比不形成銅管之擴徑部的外徑稍大。The invention of claim 3, wherein the outer diameter of the reduced diameter portion of the annular portion is slightly larger than the outer diameter of the enlarged diameter portion where the copper tube is not formed.
申請專利範圍第4項之發明如申請專利範圍第1至3項中任一項之撓性管，其中，編織線之連接側端部嵌入銅管之擴徑部與環狀物之縮徑部之間，其先端與環狀物之縮徑部之先端一起熔接固定於銅管上而產生連接。The flexible pipe according to any one of claims 1 to 3, wherein the connecting side end portion of the braided wire is embedded in the enlarged diameter portion of the copper pipe and the reduced diameter portion of the ring Between the apex and the tip end of the reduced diameter portion of the ring, the tip end is welded and fixed to the copper tube to form a connection.
本發明如前所述，銅管之連接側端部形成為擴徑部，此擴徑部之先端熔接固定於波紋軟管而產生連接，並且，在覆蓋擴徑部之外周的狀態下，上述環狀物之銅管側端部形成為縮徑部，此縮徑部之先端以可沿著軸方向嚙合於上述擴徑部之狀態熔接固定於上述銅管而產生連接，所以，當進行連接時，除了熔接固定，亦可期待相互嚙合之擴徑部與縮徑部所產生之強度，得到連接之強度特別高之效果。因此，產生如過去那種製品品質下降問題等擔憂一掃而空且強度亦很充分的撓性管。又，當進行連接時，熔接時所使用之焊接材料的量也可比過去少，所以，得到製造費用得以壓低至低價的效果。According to the present invention, the connecting side end portion of the copper pipe is formed as an enlarged diameter portion, the tip end of the enlarged diameter portion is welded and fixed to the corrugated hose to be connected, and in the state of covering the outer circumference of the enlarged diameter portion, the above The copper tube side end portion of the ring is formed as a reduced diameter portion, and the tip end of the reduced diameter portion is welded and fixed to the copper tube in a state of being engageable in the axial direction in the axially enlarged portion, and is connected, so that the connection is made. In addition to the welding fixation, the strength of the enlarged diameter portion and the reduced diameter portion that are in mesh with each other can be expected, and the strength of the connection is particularly high. Therefore, there is a coiled pipe which has a worrying problem such as a decrease in the quality of the product as in the past, and which is sufficiently clean and strong in strength. Moreover, when the connection is made, the amount of the welding material used at the time of welding can be made smaller than in the past, so that the manufacturing cost can be reduced to a low price.
以下將一邊參照圖面，一邊說明本發明之撓性管之其中一實施型態。Hereinafter, one embodiment of the flexible tube of the present invention will be described with reference to the drawings.
在第1圖中，1為圓筒狀之撓性管。此撓性管1具有波紋軟管2、近乎覆蓋整個波紋軟管2之外周的編織線3、一對與波紋軟管2之兩端部熔接固定而產生連接的銅管4及一對覆蓋且嵌入編織線3之兩端部之外周的環狀物5。以下亦將參照第2圖來說明構造中之各元件。In Fig. 1, 1 is a cylindrical flexible tube. The flexible tube 1 has a corrugated hose 2, a braided wire 3 covering almost the entire circumference of the entire corrugated hose 2, a pair of copper tubes 4 welded and fixed to both ends of the corrugated hose 2 to form a connection, and a pair of coverings. The ring 5 is embedded in the outer periphery of both ends of the braided wire 3. The components in the construction will also be described below with reference to Fig. 2.
波紋軟管2亦稱為波紋管，採用不鏽鋼(SUS)製造，形成之長度為300mm，外徑為10~60ψ。波紋軟管2之兩端圓筒部之間形成蛇腹狀之波紋管部6。在波紋管部6上兩端部之山谷間距形成得比中央部之山谷間距小。藉由此種構造，包括容易彎曲且可承受強大衝擊、壓縮這種工作性優良之特徵。The corrugated hose 2, also known as a bellows, is made of stainless steel (SUS) and has a length of 300 mm and an outer diameter of 10 to 60 。. A bellows-shaped bellows portion 6 is formed between the cylindrical portions at both ends of the corrugated hose 2. The valley pitch at both end portions of the bellows portion 6 is formed to be smaller than the valley pitch of the central portion. With such a configuration, it is characterized in that it is easy to bend and can withstand strong impact, and compression is excellent in workability.
編織線3亦稱為編織體，在其編織構造中，將並列配置複數個不鏽鋼材料而形成一束的物件，根據波紋軟管2之外徑，以不產生間隙之交叉角及編織數編織成管狀，然後再將此構造形成基本之一層，如此可達到防止波紋軟管2之延伸並保護波紋軟管2不受到外力傷害之效果。亦即，若只使用波紋軟管2，當賦予其壓力時，波紋管部6會延伸至主體，為了防止此種延伸，以編織線3來覆蓋。此外，雖然一般採用一層，但亦可根據用途將複數層重疊而提高拉伸強度。編織線3橫跨此種波紋軟管2之外周之近乎全面，其兩端部以從波紋軟管2之兩端部稍微突出至外方的長度來覆蓋。The braided wire 3 is also referred to as a braid. In the braided structure, a plurality of stainless steel materials are arranged side by side to form a bundle of articles, and the outer diameter of the corrugated hose 2 is knitted according to the crossing angle and the number of knitting without generating a gap. The tubular shape is then formed into a substantially one layer, so that the effect of preventing the extension of the corrugated hose 2 and protecting the corrugated hose 2 from external forces can be achieved. That is, if only the corrugated hose 2 is used, the bellows portion 6 extends to the main body when the pressure is applied thereto, and is covered with the braided wire 3 in order to prevent such extension. Further, although one layer is generally used, it is also possible to increase the tensile strength by overlapping a plurality of layers depending on the application. The braided wire 3 is nearly uniform across the outer circumference of the corrugated hose 2, and both end portions thereof are covered with a length slightly protruding from the both end portions of the corrugated hose 2 to the outside.
一對銅管4互為相同構造。若針對其中一銅管4作說明，其為銅製，長度100~200mm，外徑6~50ψ且在整體上形成比波紋軟管2稍小之外徑，形成於該外徑連接側之端部會慢慢的變成擴開狀而形成擴徑部7。另外，擴徑部7之先端之最大外徑與波紋軟管2之外徑近乎相等。The pair of copper tubes 4 have the same configuration with each other. For the description of one of the copper tubes 4, it is made of copper, has a length of 100 to 200 mm, an outer diameter of 6 to 50 ψ and forms a smaller outer diameter than the corrugated hose 2 as a whole, and is formed at the end of the outer diameter connection side. The enlarged diameter portion 7 is formed by gradually expanding into an expanded shape. Further, the maximum outer diameter of the tip end of the enlarged diameter portion 7 is almost equal to the outer diameter of the corrugated hose 2.
一對環狀物5互為相同構造。若針對其中一環狀物5作說明，其為不鏽鋼(SUS)製，形成之長度為30~60mm，外徑為14~70ψ。另外，環狀物5以覆蓋銅管4之擴徑部7之外周的狀態，嵌插至波紋軟管2之連接側端部。環狀物5於連接側之端部慢慢變為縮徑狀態，形成沿著軸方向嚙合於擴徑部7的縮徑部8。環狀物5之縮徑部8之先端之最小外徑比不形成銅管4之擴徑部7的外徑，亦即，管本體部9之外徑，還來得稍大。換言之，從第2圖可看出，環狀物5之縮徑部8之縮徑傾斜度與銅管4之擴徑部7之擴徑傾斜度幾乎相等，並且，在其先端與不形成銅管4之擴徑部7的管本體部9之外周面之間，形成很窄之環狀間隙。此環狀間隙變成跟編織線3之上述端部之端緣與管本體部9之外周面之間的環狀間隙一起進行熔接時的焊材填入部。The pair of rings 5 have the same structure with each other. For the description of one of the rings 5, it is made of stainless steel (SUS) and has a length of 30 to 60 mm and an outer diameter of 14 to 70 Å. Moreover, the ring 5 is inserted into the outer side of the enlarged diameter portion 7 of the copper pipe 4, and is inserted into the connection side end portion of the corrugated hose 2. The end portion of the ring-shaped object 5 is gradually reduced in diameter at the end portion on the side of the connection, and the reduced-diameter portion 8 that meshes with the enlarged diameter portion 7 in the axial direction is formed. The minimum outer diameter of the tip end of the reduced diameter portion 8 of the ring 5 is smaller than the outer diameter of the enlarged diameter portion 7 where the copper pipe 4 is not formed, that is, the outer diameter of the pipe main portion 9. In other words, as can be seen from Fig. 2, the reduced diameter inclination of the reduced diameter portion 8 of the annular member 5 is almost equal to the expanded diameter inclination of the enlarged diameter portion 7 of the copper pipe 4, and copper is not formed at the tip end thereof. A narrow annular gap is formed between the outer circumferential surfaces of the tube main body portion 9 of the enlarged diameter portion 7 of the tube 4. This annular gap becomes a welding material filling portion when the end edge of the end portion of the braided wire 3 and the annular gap between the outer peripheral surface of the pipe main body portion 9 are welded together.
若要製作如上所述之撓性管1，首先，將近乎整個外周以編織線3覆蓋之波紋軟管2切割成所需要之任意長度，分別在其切割兩端部使銅管4之擴徑部7之先端相向，藉由熔接該擴徑部之先端與波紋軟管2而進行固定。第2圖表示塗黑部位B進行熔接時所使用的焊材。接著，在覆蓋該熔接部而配置的編織線3之端部外周，從銅管4那側嵌插之環狀物5以其縮徑部8於其與銅管4之擴徑部7之間夾持編織線3之端緣的狀態，獲得重合與定位。接著，將環狀物5之縮徑部8之先端與銅管4之本體部9之外周面之間、編織線3之端部與管本體部9之外周面之間以上述環狀間隙以焊材埋入之方式進行熔接固定。第2圖表示塗黑部位C在熔接時所使用的焊材。藉此，第1圖及第2圖所示之撓性管1被製作出來。To make the flexible tube 1 as described above, first, the corrugated hose 2 covered with the braided wire 3 is cut into almost any length as needed, and the diameter of the copper tube 4 is expanded at both ends of the cut. The tip end of the portion 7 is opposed to each other by welding the tip end of the enlarged diameter portion and the corrugated hose 2. Fig. 2 shows a welding material used when the blackened portion B is welded. Next, the ring 5 inserted from the side of the copper pipe 4 on the outer periphery of the end portion of the braided wire 3 disposed so as to cover the welded portion is between the reduced diameter portion 8 and the enlarged diameter portion 7 of the copper pipe 4 The state of the end edge of the braided wire 3 is clamped to obtain coincidence and positioning. Next, between the tip end of the reduced diameter portion 8 of the ring 5 and the outer peripheral surface of the body portion 9 of the copper pipe 4, between the end portion of the braided wire 3 and the outer peripheral surface of the pipe body portion 9, the annular gap is The welding material is embedded in a manner to be welded and fixed. Fig. 2 shows the welding material used when the blackened portion C is welded. Thereby, the flexible tube 1 shown in Figs. 1 and 2 is produced.
當進行此種製作時，可從同一圖看出，熔接如塗黑部位B,C所示，可僅限於一部分，特別是如塗黑部位C所示，可為上述環狀間隙上之半徑方向之小面積，沒有如過去那樣橫跨環狀物與銅管之段差部上所形成之半徑方向之大面積而進行熔接的必要，所以，可節省焊材的量，進而將製作費用壓低至低價。When such a fabrication is made, it can be seen from the same figure that the fusion, as indicated by the blackened portions B, C, may be limited to only a portion, particularly as indicated by the blackened portion C, which may be the radial direction on the annular gap. The small area is not required to be welded across a large area in the radial direction formed on the stepped portion of the ring and the copper tube as in the past. Therefore, the amount of the welding material can be saved, and the manufacturing cost can be lowered to a low level. price.
接著，說明其作用。前述之撓性管1設置於第3圖所示之空調裝置之冷媒循環用配管之管線上來使用。在此例中，具體而言，在設置於啤酒屋上之一對多空調機(室外機)11與冷媒循環用配管12之間進行連接而設置。室外機11透過防震機構15設置於基台14上，其內部收納有壓縮器等。此外，屋上之架台13上所配置之配管12收納於未圖示之儲物箱中。Next, the effect will be described. The above-described flexible tube 1 is used in a line for a refrigerant circulation pipe of an air conditioner shown in Fig. 3. In this example, specifically, a pair of multi-air conditioners (outdoor units) 11 and a refrigerant circulation pipe 12 provided in the beer house are connected to each other. The outdoor unit 11 is provided on the base 14 via the anti-vibration mechanism 15, and a compressor or the like is housed therein. Further, the piping 12 disposed on the gantry 13 on the house is housed in a storage box (not shown).
在上述使用例中，於室外機11之運轉期間，從室外機內之壓縮器等所產生之振動透過防震機構15到達配管連接部，亦即，撓性管1，對該撓性管產生負載，不過，在撓性管1上，波紋軟管2之波紋管部6適度彎曲，吸收該振動。又，在撓性管1上，波紋軟管2與銅管4彼此之間在軸方向有使其分離之力作用於上，不過，在此時，環狀物5之縮徑部8與銅管4之擴徑部7於軸方向相互嚙合，成為不使其脫離之抗力。因此，波紋軟管2與銅管4為除了熔接處還包括上述嚙合而產生之抗力也有高強度的元件。於是，波紋軟管2與銅管4、環狀物5之連接強度也很充分，不會像過去那樣有製品品質下降的情況。又，不僅在室外機11內有振動之情況下，在室外機11因颱風、地震等而有巨大搖晃的情況下，也有同樣的力在作用，不過，在此種情況下也一樣，伴隨該搖晃之振動會被撓性管1吸收，亦即，藉由環狀物5之縮徑部8與銅管4之擴徑部7之嚙合，發揮抵抗脫離之抗力而可期待相同效果。In the above-described use example, during the operation of the outdoor unit 11, the vibration generated from the compressor or the like in the outdoor unit passes through the anti-vibration mechanism 15 to the pipe connection portion, that is, the flexible tube 1 loads the flexible tube. However, on the flexible tube 1, the bellows portion 6 of the corrugated hose 2 is moderately bent to absorb the vibration. Further, in the flexible tube 1, the corrugated tube 2 and the copper tube 4 have a force for separating them in the axial direction, but at this time, the reduced diameter portion 8 of the ring 5 and the copper The enlarged diameter portions 7 of the tubes 4 are meshed with each other in the axial direction, and are resistant to being detached. Therefore, the corrugated hose 2 and the copper pipe 4 are elements which have high strength in addition to the above-mentioned meshing in addition to the welding. Therefore, the connection strength between the corrugated hose 2 and the copper pipe 4 and the ring 5 is also sufficient, and the product quality is not deteriorated as in the past. Further, not only when there is vibration in the outdoor unit 11, but also when the outdoor unit 11 is greatly shaken by typhoons, earthquakes, or the like, the same force acts, but in this case, the same is true. The vibration of the sway is absorbed by the flexible tube 1, that is, the same effect can be expected by the meshing portion 8 of the ring 5 and the enlarged diameter portion 7 of the copper tube 4, and exhibiting resistance against detachment.
在如前述之範例中，過去將室外機11與冷媒循環用配管12直接連接起來。因此，當有從壓縮器等所產生之振動或颱風、地震等所產生之巨大搖晃時，振動到達配管12，配管連接部上產生負載，恐怕在配管12內循環之冷媒氣體會洩漏出來。不過，如前所述，若藉由撓性管1連接室外機11與冷媒循環用配管12，伴隨此種搖晃之振動即使會傳遞，如前所述，波紋軟管2之波紋管部6也會適度彎曲而吸收該振動。因此，沒有如前所述之冷媒氣體洩漏出來的掛慮。In the above-described example, the outdoor unit 11 and the refrigerant circulation pipe 12 are directly connected in the past. Therefore, when there is vibration caused by a compressor or the like, or a large sway caused by a typhoon, an earthquake, or the like, the vibration reaches the pipe 12, and a load is generated at the pipe connection portion, and the refrigerant gas circulating in the pipe 12 may leak. However, as described above, when the outdoor unit 11 and the refrigerant circulation pipe 12 are connected by the flexible tube 1, the vibration accompanying such shaking is transmitted, and as described above, the bellows portion 6 of the corrugated hose 2 is also It will bend moderately to absorb the vibration. Therefore, there is no concern that the refrigerant gas leaked as described above.
又，有時會為了防震機構15之維修、交換等而抬起以配管12連接之室外機11，不過，當進行此種抬起動作時，波紋軟管2之波紋管部6也會適度彎曲而吸收振動。Further, the outdoor unit 11 connected to the pipe 12 may be lifted for maintenance, exchange, or the like of the anti-vibration mechanism 15, but the bellows portion 6 of the corrugated hose 2 may be moderately bent when such a lifting operation is performed. And absorb the vibration.
再者，若使用上述撓性管1，空調用管等中之配管作業也可輕易進行，並且，可在配管作業之後吸收搖晃、振動等，所以，即使不同下沉程度之配管位置偏移發生，也可吸收位置偏移量。In addition, when the flexible pipe 1 is used, piping work in an air-conditioning pipe or the like can be easily performed, and shaking, vibration, and the like can be absorbed after the piping operation, so that the piping position shift occurs even if the degree of sinking is different. , can also absorb the position offset.
上述實施型態僅代表其中一最佳實施例，本發明在申請專利範圍所記載之範圍內，進一步包含其他不同之適當實施型態。波紋軟管2、編織線3、銅管4及環狀物5也僅為其中一例，可置換為其他具有相同效果之構造。又，形成於銅管4之擴徑部7、形成於環狀物5之縮徑部8之具體構造也可為圖示以外之其他構造。The above-described embodiments are merely representative of one of the preferred embodiments, and the present invention further includes other suitable embodiments within the scope of the claims.
