Description
Technical field
The utility model relates to a kind of pipe joint, specifically, relates to a kind of two clamp-press type metallic conduit links of asymmetric bulge loop that are applicable to the high leak tightness place.
Background technique
Clamp-press type pipe is progressively applied in the various low-pressure fluid pipeline systems in a plurality of fields such as building, feedwater, combustion gas, medicine, oil and chemical industry, but in the existing clamp-press type pipe because the seal groove shaped design problem of O-ring seals is installed, in work progress, go wrong easily, cause the seal ring connecting tube to poke when mounted easily, thereby cause sealing effect poor, and it is big that card pressure is installed, loss to instrument is big, thereby has also reduced the working life of card press tool.
In addition, in the pipeline system of or toxic gas inflammable and explosive at some, it still is not enough that common link only adopts physical seal, and Security can not be up to standard, in case gas leakage occurs, will bring immeasurable serious consequence.
The utility model content
The utility model is intended to overcome above-mentioned the deficiencies in the prior art, a kind of metallic conduit link is provided, and it is good sealing effect not only, and greatly reduces card pressure, prolong the working life of card press tool, be particularly suitable in the pipeline system of inflammable and explosive or toxic gas.
The metallic conduit link that provides according to the utility model comprises a connection piece body, this link body is provided with a plurality of pipe joints that are interconnected, be equipped with the pipe fitting that inserts into the inner in each described pipe joint, the inwall of each described pipe joint and stretch between wherein the pipe fitting and be provided with adhered layer, described link body, each pipe joint and each pipe fitting are that metallic material is made, and described adhered layer is an anaerobic adhesive.
Each described pipe joint is equipped with a bulge loop near its port, is provided with seal ring in this bulge loop.
The circumferential both sides of each described bulge loop are asymmetric setting.
Side that each described bulge loop is circumferential and described pipe joint are the orthodrome transition, opposite side and the angled hypotenuse of described pipe joint.
The circumferential described side of each described bulge loop is the side of bulge loop near described pipe joint port.
Be equipped with one on each described pipe joint along the positioning section that concaves in week.
Described seal ring matches with described bulge loop.
Described link body is two logical, threeway or four-way.
Described seal ring is made by rubber material.
The relative prior art of the utility model has following advantage:
Described bulge loop is asymmetric bulge loop, and side that each described bulge loop is circumferential and described pipe joint are the orthodrome transition, opposite side and the angled hypotenuse of described pipe joint.Therefore; this structure has improved described pipe joint and the card of described pipe fitting when construction pressed effect; in card pressure work progress, make things convenient for flowing of metal; make that not only the sealing effect between described pipe joint and the described pipe fitting is better; protected seal ring; and greatly reduce card pressure, convenient construction and prolonged working life of card press tool.In addition, the utility model has additional the anaerobism glue-line between bulge loop and positioning section, can play the effect of second layer sealing, is particularly suitable in the pipeline system of some inflammable and explosive or toxic gases.
Description of drawings
Fig. 1 is the structure sectional view of the utility model metallic conduit link;
Fig. 2 is the structure sectional view (omitted anaerobism glue-line) of the utility model card after pressing.
Embodiment
Below in conjunction with accompanying drawing the utility model is further set forth.
As depicted in figs. 1 and 2, a kind of optimal way of the utility model metallic conduit link, it comprises a connection piece body 1, this link body 1 is provided with a plurality of pipe joints that are interconnected 2, be equipped with the pipe fitting 3 that inserts into the inner in each described pipe joint 2, described link body 1, each pipe joint 2 and each pipe fitting 3 are made for metallic material, the inwall of each described pipe joint 2 and stretch between wherein the pipe fitting 3 and be provided with adhered layer 6, and described adhered layer 6 is an anaerobic adhesive.Can play good sealing effect by anaerobic adhesive like this, be specially adapted in the pipeline system of some inflammable and explosive or toxic gases.The utility model also all is provided with a bulge loop 4 at each described pipe joint 2 near its port 21 places, be provided with the seal ring 5 that matches with it and make by rubber in this bulge loop 4, the circumferential both sides of described bulge loop 4 are asymmetric setting, each described bulge loop 4 a circumferential side and described pipe joint 2 is orthodrome 41 transition, the hypotenuse 42 that opposite side and described pipe joint 2 are angled, each described bulge loop 4 circumferential described side is the side of bulge loop near described pipe joint 2 ports 21.In sum, this structure helps described pipe joint 2 and described pipe fitting 3 makes things convenient for flowing of metal in card pressure work progress, and unlikely pipe joint 2 and described pipe fitting 3 are catcher mark in the construction of card pressure, solve existing pipe fitting and easily poked the defective of seal ring 5, and then protected described seal ring 5, guarantee that simultaneously described seal ring 5 has correlation space to stretch in card pressure process, guaranteeing to avoid described seal ring 5 to surpass the limit of compression ratio under the prerequisite of good sealing effect, greatly reduce card pressure simultaneously, prolonged the working life of card press tool; And this is simple in structure, safe and reliable.
Wherein, each described bulge loop 4 a circumferential side and described pipe joint 2 is orthodrome 41 transition, that is to say between described orthodrome 41 and the described port 21 and also be provided with a segment distance, this is apart from pressing used for two cards, be equipped with one on each described pipe joint 2 along the positioning section 22 that concaves in week, the described pipe fitting 3 of these positioning section 22 may command stretches into the position in the described pipe joint 2.Link body 1 of the present utility model is two logical, threeway or four-way, described pipe joint 2 is the shape of Fig. 2 with pipe fitting 3 after card is pressed construction, card presses each described bulge loop 4 circumferential both sides, back to be deformed into hexahedron, the described pipe joint 2 in distortion back closely links into an integrated entity with described pipe fitting 3, and described seal ring 5 is rationally forming excellent sealing with described pipe joint 2 and pipe fitting 3 in the compression zone.
