Description

폴리우레탄폼 압력용기용 디스펜싱 어댑터 {DISPOSABLE DISPENSING ADAPTER FOR ONE-COMPONENT POLYURETHANE FOAM}DISPOSABLE DISPENSING ADAPTER FOR ONE-COMPONENT POLYURETHANE FOAM BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

본 발명은 폴리우레탄폼 압력용기용 디스펜싱 어댑터에 관한 것이다.The present invention relates to a dispensing adapter for a polyurethane foam pressure vessel.

건축물 등 다양한 분야에 단열, 방음, 내부 충전, 밀봉 등의 목적으로 널리 사용되는 폴리우레탄은 고압가스와 함께 압력용기에 충전되어 소비자에게 제공된다.Polyurethane which is widely used for various purposes such as insulation, soundproofing, internal filling, sealing, etc., is filled with high pressure gas in a pressure vessel and supplied to consumers.

폴리우레탄이 충전된 압력용기는 어댑터 타입(adapter type)과 건 타입(gun type)으로 판매되고 있으며, 어댑터 타입에는 일회용 어댑터를 장착하여 사용하고, 건 타입에는 어댑터보다 비교적 가격대가 높은 건을 장착하여 사용한다.Polyurethane filled pressure vessels are sold as adapter type and gun type. Adapter type is equipped with disposable adapter. Gun type is equipped with relatively high price gun use.

건은 어댑터보다 가격대가 높기 때문에 전문가가 아닌 일반인이 구비하는 경우가 드물기 때문에 단기간 사용을 위해 건을 구매하는 것은 가격면에 있어 부담스러움을 느낄 수 있다. 뿐만 아니라 일반인은 건을 사용하기 다소 어려움이 있을 수 있기 때문에 건보다는 일회용 어댑터를 사용하는 것이 바람직하다.Because guns are more expensive than adapters, it is rare for an average person to have them, so buying a gun for short-term use can be a burden for the price. In addition, it is desirable to use disposable adapters rather than guns because the general public may have some difficulty using guns.

또한 전문가라 하더라도 폴리우레탄을 분사하는 위치에 따라서 건보다는 일회용 어댑터를 사용하기 용이한 경우도 있다.Also, even if you are a professional, you may find it easier to use disposable adapters rather than guns depending on where you are spraying polyurethane.

따라서, 본 발명은 건 타입(gun type)의 압력용기에 사용가능한 폴리우레탄 폼 압력용기용 디스펜싱 어댑터를 제공하는 것이다.Accordingly, it is an object of the present invention to provide a dispensing adapter for a polyurethane foam pressure vessel which can be used in a pressure vessel of a gun type.

상기와 같은 본 발명의 목적은, 디스펜싱 건 장착부를 갖는 상단 캡에 축방향 탄성 변위 및 축방향에 대한 경사 탄성변위 가능하게 설치되며 반경방향 외측으로 돌출된 고리상의 걸림플랜지를 갖는 관상의 밸브스템을 가지는 폴리우레탄폼 압력용기와, 밸브 스템이 삽입되는 관상의 어댑터 본체와, 어댑터 본체의 일단부에 형성된 배출관부와, 어댑터 본체의 타단부에 연장형성되어 상기 밸브스템의 내부에 삽입되는 삽입관부와, 상기 삽입관부의 둘레에 형성되어 상기 걸림플랜지에 이탈방지되도록 걸리는 내향 물림플랜지를 갖는 물림스커트부와, 상기 어댑터 본체의 외벽으로부터 연장된 작동레버부에 의해 달성된다.It is an object of the present invention to provide a tubular valve stem having an annular resilient displacement in an upper cap having a dispensing gun mounting portion and a hooking flange protruding in a radially outward direction, A discharge tube portion formed at one end of the adapter body, and an insertion tube portion extending from the other end portion of the adapter body and inserted into the valve stem, And an engaging skirt portion formed around the insertion tube portion and having an inwardly facing flange engaged with the engaging flange so as to be separated from the engaging flange, and an operation lever portion extending from an outer wall of the adapter body.

물림스커트부는 삽입방향을 따라 확장되는 절두원추형상인 것이 바람직하다. The engaging skirt portion is preferably a truncated conical shape extending along the insertion direction.

물림플랜지는 원주방향을 따라 상호 이격된 복수의 플랜지부분을 가지며, 각 플랜지부분은 원주방향을 따라 점진적으로 내향 확장되는 것이 바람직하다.The engagement flanges have a plurality of flange portions spaced apart from each other along the circumferential direction, and each flange portion is preferably gradually inwardly expanded along the circumferential direction.

그리고, 어댑터 본체의 외벽면으로부터 일체로 연장되어 상기 디스펜싱 건 장착부에 착탈가능하게 결합되는 걸이부를 더 포함하는 것이 바람직하다.It is further preferable that the apparatus further includes a hook portion integrally extended from an outer wall surface of the adapter body and detachably coupled to the dispensing gun mounting portion.

작동레버는 적어도 1회 절곡되어 상기 압력용기의 영역에까지 연장되며, 또한. 어댑터 본체에 일체 형성된 고정 레버부와 고정 레버부에 착탈 가능하게 결합되는 연장 레버부를 갖는 것이 바람직하다.The operating lever is bent at least once to extend into the area of the pressure vessel, and furthermore, It is preferable to have a fixed lever portion formed integrally with the adapter body and an extended lever portion detachably coupled to the fixed lever portion.

이에 따라, 본 발명은 건 타입의 압력용기에 단가가 높은 전용 건 대신에 디스펜싱 어댑터를 사용하여 폴리우레탄을 발포시에 비용을 절감시키는 효과를 제공한다.Accordingly, the present invention provides a cost-saving effect in foaming polyurethane using a dispensing adapter instead of a high-cost dedicated gun in a gun-type pressure vessel.

이하, 첨부된 도면을 참조하여 본 발명에 따른 바람직한 실시예를 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1에 도시된 바와 같이 일회용 디스펜싱 어댑터(100)는 디스펜싱 건 장착부를 가지는 폴리우레탄폼 압력용기(PC)에 장착된다. 압력용기(PC)의 상단 캡에 축방향 탄성 변위 및 축방향에 대한 경사 탄성변위를 가능하게 설치된 밸브스템(VS)이 존재한다.As shown in FIG. 1, the disposable dispensing adapter 100 is mounted in a polyurethane foam pressure vessel (PC) having a dispensing gun mount. There is a valve stem (VS) installed in the upper end cap of the pressure vessel (PC) so as to enable axial elastic displacement and inclined elastic displacement with respect to the axial direction.

도 2에 도시된 바와 같이 압력용기(PC)의 상단부에 형성된 밸브스템(VS)에 결합되는 관상의 어댑터 본체(110)와, 어댑터 본체(110)의 일단부에 형성된 배출관부(120)와, 어댑터 본체(110)의 타단부에 형성된 삽입관부(130)와, 삽입관부(130)의 둘레에 형성된 물림스커트부(140)와, 어댑터 본체(110)의 외벽으로부터 연장된 작동레버(150)를 포함한다.A tubular adapter body 110 coupled to a valve stem VS formed at an upper end of the pressure vessel PC as shown in FIG. 2, a discharge tube 120 formed at one end of the adapter body 110, An engaging skirt portion 140 formed around the insertion tube portion 130 and an operation lever 150 extending from the outer wall of the adapter body 110. The insertion tube portion 130 is formed at the other end portion of the adapter body 110, .

삽입관부(130) 및 배출관부(120)는 압력용기(PC)로부터 폴리우레탄폼을 외부로 배출하기 위하여 어댑터 본체(110)의 일단부 및 타단부에 형성되며, 삽입관부(130)는 밸브스템(VS)의 내부에 삽입되고 배출관부(120)는 폴리우레탄폼이 이동하는 긴 막대형상의 토출관(122) 내부에 결합되어 있다. 따라서 폴리우레탄폼은 압력용기(PC)에서 삽입관부(130)와 어댑터 본체(110)를 지나 배출관부(120)와 연결된 토출관(122)에 의해 외부로 배출된다. 경우에 따라서 배출관부(120)와 토출관(122)은 일체형으로 이루어질 수 있다.The insertion tube portion 130 and the discharge tube portion 120 are formed at one end and the other end of the adapter body 110 for discharging the polyurethane foam from the pressure vessel PC to the outside, And the discharge pipe portion 120 is coupled to the inside of the long bar-shaped discharge pipe 122 through which the polyurethane foam moves. The polyurethane foam is discharged to the outside by the discharge tube 122 connected to the discharge tube portion 120 through the insertion tube portion 130 and the adapter body 110 in the pressure vessel PC. The discharge tube portion 120 and the discharge tube 122 may be integrally formed.

삽입관부(130)의 둘레에는 삽입관부(130)가 밸브스템(VS)에서 이탈되지 않도록 내부로 돌출된 물림플랜지(142)를 갖는 물림스커트부(140)가 형성되어 있다. 물림스커트부(140)는 밸브스템(VS)에 존재하는 반경방향 외측으로 돌출된 고리상의 걸림플랜지(FL)에 걸린다. 따라서, 어댑터 본체(110)를 밸브스템(VS)에 삽입시키면, 외향으로 확장된 물림스커트부(140)가 절두원추형상의 걸림플랜지(FL)를 감싸서 맞물리게 되어 안정된 결합을 하게 된다. 걸림플랜지(FL)와 마찬가지로 물림스커트부(140) 또한 삽입방향을 따라 점점 확장되는 절두원추형상으로 이루어져 있다.A bite skirt portion 140 having an engaging flange 142 projecting inward is formed around the insertion tube portion 130 such that the insertion tube portion 130 is not separated from the valve stem VS. The bite skirt portion 140 engages the engagement flange FL on the ring radially outwardly projecting on the valve stem VS. Therefore, when the adapter main body 110 is inserted into the valve stem VS, the outwardly extended skirt portion 140 is engaged with the engaging flange FL of the truncated conical shape to provide stable engagement. Like the engagement flange FL, the engagement skirt portion 140 is also formed as a truncated conical shape gradually expanding along the insertion direction.

도 3에 도시된 바와 같이 물림스커트부(140)에 내부 방향으로 존재하는 물림플랜지(142)는 원주방향을 따라 서로 이격된 복수의 플랜부부분(142a, 142b, 142c)을 가지며, 각 플랜부부분(142a, 142b, 142c)은 원주방향을 따라 점진적으로 물림스커트부(140)의 내부 방향으로 확장된다. 만약 물림플랜지(142)가 물림스커트부(140)의 내부 방향으로 연장된 일체형으로 존재할 경우 물림플랜지(142) 사이에 여유공간이 없어 탄성변형에 제약을 받게 된다. 따라서 물림플랜지(142)의 플랜부부분(142a, 142b, 142c)이 서로 이격되어 있을 경우에는 물림스커트부(140)와 밸브스템(VS)을 결합시킬 때 힘을 많이 들이지 않아도 되며, 밸브스템(VS)에서 물림스커트부(140)를 분리할 때에도 쉽게 분리 가능하다.As shown in FIG. 3, the engagement flanges 142, which are present inwardly in the bite skirt portion 140, have a plurality of planar portions 142a, 142b, 142c spaced from one another along the circumferential direction, The portions 142a, 142b, 142c extend inwardly of the skirt portion 140, which progressively fades along the circumferential direction. If the engagement flange 142 is integrally extended in the inward direction of the engagement skirt portion 140, there is no space between the engagement flanges 142, so that elastic deformation is limited. Therefore, when the flange portions 142a, 142b, 142c of the engagement flange 142 are spaced apart from each other, there is no need to increase the force when the engaging skirt portion 140 and the valve stem VS are engaged, VS when the bite skirt portion 140 is detached.

도 4에 도시된 바와 같이 디스펜싱 어댑터(100)는 어댑터 본체(110)의 외벽면으로부터 일체로 연장되어 디스펜싱 건 장착부에 착탈가능하도록 결합되는 걸이부(160)가 존재한다. 걸이부(160)를 이용하여 압력용기에 고정되도록 장착시켜 디스펜싱 어댑터(100)가 압력용기와 함께 보관 또는 수송이 용이하도록 한다.4, the dispensing adapter 100 includes a hook 160 which is integrally extended from an outer wall surface of the adapter body 110 and is detachably coupled to the dispensing gun mounting part. So that the dispensing adapter 100 can be easily stored or transported together with the pressure vessel.

또한, 디스펜싱 어댑터(100)는 어댑터 본체(110)의 외벽으로부터 연장된 작동레버(150)를 포함한다. 작동레버(150)는 압력용기(PC)에서 폴리우레탄폼이 배출되도록 하는 것으로 폴리우레탄폼을 배출시킬 때에는 압력용기(PC)를 거꾸로 세워 파지하고, 작동레버(150)를 경사지게 윗 방향으로 잡아당긴다. 작동레버(150)의 작동에 의해 밸브스템(VS)의 하단부가 기울어지면서 밸브가 개방되어 압력용기 내에 충전된 폴리우레탄 액이 밸브스템(VS)을 통해 디스펜싱 어댑터(100)로 나오게 된다. 외부로 밀려나온 액상의 폴리우레탄은 어댑터 본체(110)를 지나 배출관부(120), 토출관(122)을 통하여 목표로 하는 부위로 배출된다.The dispensing adapter 100 also includes an actuating lever 150 extending from the outer wall of the adapter body 110. The operation lever 150 allows the polyurethane foam to be discharged from the pressure vessel PC. When discharging the polyurethane foam, the pressure vessel PC is held upside down and the operation lever 150 is tilted upwardly . The lower end of the valve stem VS is tilted by the operation of the operation lever 150 and the valve is opened so that the polyurethane liquid filled in the pressure vessel is discharged to the dispensing adapter 100 through the valve stem VS. The liquid polyurethane pushed out to the outside passes through the adapter body 110 and is discharged to a target site through the discharge tube portion 120 and the discharge tube 122.

도 5에 도시된 바와 같이 제2실시예에 따른 디스펜싱 어댑터(100)의 작동레버(250)는 적어도 1회 절곡되어 압력용기(PC)의 길이방향을 따라 연장된 연장레버부(252)와, 연장레버부(252)와 결합되는 고정레버부(254)로 이루어져 있다. 기존의 작동레버를 사용할 경우 한 손은 압력용기(PC)를, 다른 한 손으로는 작동레버를 동작시켜야 한다는 불편함이 있었다. 하지만 도시된 실시예의 작동레버(250)를 사용할 경우 한 손으로 압력용기(PC)와 연장레버부(252) 모두를 쥐고 작동레버(250)를 동작시킬 수 있어 사용자가 작업하기 용이해진다. 또한 고정레버부(254)와 연장레버부(252)를 포함하는 작동레버(250)는 착탈식으로 이루어지는 것이 가능하다. 고정레버부(254)에는 연장레버부(252)가 삽입될 수 있는 삽입구(254a)를 마련한다. 따라서, 연장레버부(252)를 압력용기(PC)의 포상, 수송 및 보관시에는 삽입구(254a)로부터 분리시키고, 디스펜싱 작업시에는 삽입구(254a)에 삽입 결합하여 사용한다. 또한 착탈식 연장레버부(252)는 제작비용 절감, 착탈의 용이성 등을 고려하여 관상체로 만들어질 수 있다.5, the operation lever 250 of the dispensing adapter 100 according to the second embodiment includes an extension lever portion 252 bent at least once and extending along the longitudinal direction of the pressure vessel PC, And a fixed lever portion 254 which is engaged with the extension lever portion 252. There is an inconvenience that when using the existing operation lever, one hand must operate the pressure vessel PC and the other hand must operate the operation lever. However, when the operation lever 250 of the illustrated embodiment is used, the operation lever 250 can be operated by holding both the pressure vessel PC and the extension lever portion 252 with one hand, thereby making it easier for the user to work. Also, the operating lever 250 including the fixed lever portion 254 and the extended lever portion 252 can be detachable. The fixed lever portion 254 is provided with an insertion port 254a into which the extension lever portion 252 can be inserted. Therefore, the extension lever portion 252 is separated from the insertion port 254a when the pressure container PC is being recharged, transported, and stored, and is inserted into the insertion port 254a for dispensing. Further, the detachable extension lever portion 252 can be made into a tubular body in consideration of reduction in manufacturing cost, ease of attachment and detachment, and the like.

도 6의 제3실시예에 따른 작동레버(350)는 제2실시예와 마찬가지로 고정레버부(354)와, 고정레버부(354)에 착탈가능하게 결합되는 연장레버부(352)를 가지고 있다. 연장레버부(352)는 고정레버부(354)에 힌지결합되며, 힌지연결은 막(膜)힌지 인 것이 바람직하다. 고정레버부(354)와 연장레버부(352)는 보관이나 포장의 편이를 위하여 가능한 크기를 줄여야 하기 때문에 기능상 힌지로 연결되도록 한다. 힌지연결은 여러 가지 방식이 가능하지만 조립과정이 필요 없고 한 번의 성형으로 일체로 제작할 수 있는 막힌지가 바람직하다.The operation lever 350 according to the third embodiment of FIG. 6 has a fixed lever portion 354 and an extended lever portion 352 that is detachably coupled to the fixed lever portion 354 as in the second embodiment . The extension lever portion 352 is hinged to the fixed lever portion 354 and the hinge connection is preferably a membrane hinge. The fixed lever portion 354 and the extended lever portion 352 are functionally hinged because they must be reduced in size to save storage or packaging. The hinge connection can be done in various ways, but it is preferable to use a closure which can be integrally manufactured by a single molding process without any assembly process.

막힌지(352a)로 연결된 연장레버부(352)는 디스펜싱 작업시에는 하향 굴곡되어 압력용기(PC)의 길이방향과 대략 평행하게 배치된다. 이때, 막힌지(352a) 부근의 압력용기(PC)를 향해 함몰 형성된 연장레버부(352)의 돌기수용부(352b)에 고정레버부(354)로부터 돌출 형성된 받침돌기(354a)가 삽입되어 결합된다. 받침돌기(354a)와 돌기수용부(352b)에 의해 결합된 연장레버부(352)와 고정레버부(354)는 마치 일체로 형성된 역 'L'자 형상을 하게 된다.The extension lever portion 352 connected to the clogged paper 352a is bent downward at the time of dispensing work and disposed substantially parallel to the longitudinal direction of the pressure vessel PC. At this time, a projecting projection 354a protruding from the fixing lever portion 354 is inserted into the projection receiving portion 352b of the extending lever portion 352 formed in the vicinity of the clogged paper 352 toward the pressure vessel PC, do. The extended lever portion 352 and the fixed lever portion 354 coupled by the support projection 354a and the projection receiving portion 352b are formed into an inverted 'L' shape as if formed integrally.

역 'L'자 형상을 하게 된 고정레버부(354)와 연장레버부(352)는 디스펜싱 작업시에 연장레버부(352)를 압력용기 쪽으로 당기면, 고정레버부(354)는 밸브스템(VS)을 경사지게 변위시키고, 이 경사변위에 의해 밸브스템(VS) 하단부가 열리게 되어 가스 압력을 받고 있는 액상의 폴리우레탄이 밸브스템(VS)의 중공부를 통하여 밀려나오게 된다. 밀려나온 폴리우레탄은 토출관(122)을 통하여 타겟부위에 디스펜싱 된다.The fixed lever portion 354 and the extended lever portion 352 which have been shaped in the inverted L shape pull the extension lever portion 352 toward the pressure vessel during the dispensing operation so that the fixed lever portion 354 is moved to the valve stem VS of the valve stem VS is inclined and the lower end of the valve stem VS is opened by the inclined displacement so that the liquid polyurethane under the gas pressure is pushed out through the hollow portion of the valve stem VS. The pushed out polyurethane is dispensed to the target portion through the discharge pipe 122.

연장레버부(352)의 단부에는 토출관(122)의 자유단부에 삽입가능한 차단돌기(352c)를 마련한다. 토출관(122)으로부터 배출된 폴리우레탄은 공기와 만나 빠른 속도로 반응하여 굳어지기 때문에 배출작업을 잠시 중단하거나 장시간 휴지하는 경우에는 토출관(122) 단부를 막아 공기와의 접촉을 차단할 필요가 있다. 도 6은 사용(실선) 및 휴지시(점선)의 상태를 도시한 것으로, 도시된 바와 같이 막힌지(352a)로 연결된 연장레버부(352)는 막힌지(352a)를 중심점으로 하여 자유스럽게 선회시켜 토출관(122) 단부쪽 가까운 거리까지 용이하게 접근시킬 수 있으며, 토출관(122) 단부쪽으로 가깝게 접근되면 연장레버부(352)의 단부에 형성된 차단돌기(352c)를 용이하게 토출관(122)의 단부에 삽입시킬 수 있다.At the end of the extension lever portion 352, a blocking protrusion 352c that can be inserted into the free end of the discharge tube 122 is provided. Since the polyurethane discharged from the discharge pipe 122 comes into contact with air and reacts at a high speed to be hardened, it is necessary to stop the discharge operation temporarily or stop the contact with the air by closing the end of the discharge pipe 122 for a long period of time . 6, the extended lever portion 352 connected to the clogged paper 352a as shown in the drawing shows the state of use (solid line) and dormant (dotted line) The blocking protrusion 352c formed at the end of the extending lever portion 352 can be easily moved toward the discharge pipe 122 As shown in Fig.
