개시되는 발명은 다층관에 적용되는 압착식 배관연결장치에 관한 것으로, 더욱 상세하게는 음용수관, 난방관을 연결하기 위해 사용되는 다층관에 적용되는 압착식 배관연결장치에 관한 것이다. More particularly, the present invention relates to a squeeze-type pipe connecting apparatus applied to a multi-layer pipe used for connecting a drinking water pipe and a heating pipe.

본 명세서에서 달리 표시되지 않는 한, 이 섹션에 설명되는 내용들은 이 출원의 청구항들에 대한 종래 기술이 아니며, 이 섹션에 포함된다고 하여 종래 기술이라고 인정되는 것은 아니다.Unless otherwise indicated herein, the contents set forth in this section are not prior art to the claims of this application and are not to be construed as prior art to be included in this section.

일반적으로, 주택과 일반상가건물에는 여러 종류의 파이프로 배관되어 있고, 파이프 종류는 강관파이프, PE파이프, 동(Cu)파이프 등이 있다.Generally, houses and general commercial buildings are piped with various kinds of pipes, and the types of pipes are steel pipes, PE pipes and copper pipes.

이러한 배관용 파이프는 연결구를 사용하여 연결하도록 되어 있다. These pipes are connected by using connectors.

종래에는 파이프의 외면에 나사산을 형성하고, 양측 파이프의 나사산에 나사결합되며 패킹이 개재된 조임구를 양측에 구비한 파이프 연결구가 많이 사용되고 있었다. Conventionally, a pipe connector provided with threads on the outer surface of the pipe and screwed to the threads of both pipes and having fasteners with the packing on both sides has been widely used.

한편 파이프 중에는 외면에 나사산을 형성시킬 수 없는 복합피복층을 갖는 다층관이 있으므로 이러한 다층관은 전술한 나사 결합방식의 연결구를 사용할 수 없는 문제점이 있었다. On the other hand, since there is a multi-layer pipe having a composite coating layer which can not form a screw thread on the outer surface of the pipe, such a multi-layer pipe can not use the above-mentioned screw connection type connector.

도 1 내지 도 4에 도시된 바와 같이, 발명의 일 실시예에 따른 다층관에 적용되는 압착식 배관연결장치(A)는, 금속관의 내,외면에 다층의 피복이 형성된 다층관(100)을 연결하는 것으로, 일단이 개구되어 있고, 내부에는 일단 개구부(22)를 관통하는 통로(24)가 형성되며, 외주면에 끼움환턱(26)이 복수개 형성되고, 복수개의 끼움환턱(26) 사이에 오링(27)이 형성되어 상기 다층관(100)에 결합되는 끼움부(28)를 구비한 몸체(2); 몸체(2)의 외주면 중간부위에 형성된 돌출부(4); 몸체(2)의 양측 끼움부에 결합되며 다층관(100)의 외주면에 압착되어 고정되는 압착부재(6);를 포함하여 구성된다. As shown in FIGS. 1 to 4, a compression pipe connection device A applied to a multi-layer pipe according to an embodiment of the present invention includes a multi-layer pipe 100 having a multi-layer coating formed on the inner and outer surfaces of a metal pipe And a plurality of fitting prongs 26 are formed on the outer circumferential surface and a plurality of fitting holes 26 are formed between the fitting prongs 26, (2) having a fitting part (28) formed with a tubular body (27) and joined to the multi-layer tube (100); A protrusion 4 formed at an intermediate portion of an outer peripheral surface of the body 2; And a pressing member 6 which is coupled to both side fitting portions of the body 2 and is pressed and fixed to the outer peripheral surface of the multi-layer tube 100.

상기 압착부재(6)는 양단이 개구되고 내부에 관통공이 형성되며 양단 개구부(62)에는 확관부(64)가 형성된다. The compression member 6 is opened at its both ends, has a through hole formed therein, and an expanded portion 64 is formed at both end opening portions 62.

확관부(64)는 개구부(22)를 향해 직경이 커지도록 하여 나팔 형상으로 형성된다. The expanded portion 64 is formed in a trumpet shape so that its diameter becomes larger toward the opening portion 22.

상기 압착부재(6)의 외면 일측 단부에는 내부에 삽입된 다층관(100)의 인입 상태를 확인할 수 있는 확인공(66)이 형성된다. A check hole 66 is formed at one end of the outer surface of the compression member 6 to check the pulled-in state of the multi-layer pipe 100 inserted therein.

확인공(66)은 돌출부(4)에 가까운 위치에 형성된다. The confirmation hole (66) is formed at a position close to the projection (4).

상기 끼움환턱(26)은 개구부(22)를 향해 하향 경사지는 경사면을 갖도록 형성됨으로써 다층관(100)을 끼우기는 쉽고, 일단 끼워진 후에는 빠지기 어려운 성능이 발휘될 수 있다. Since the fitting bottom 26 is formed to have an inclined surface inclined downward toward the opening 22, it is easy to insert the multi-layer pipe 100 and a performance that is difficult to be released once it is fitted can be exerted.

상기 압착부재(6)의 내경은 다층관(100)의 외경 보다 같거나 크게 형성된다. The inner diameter of the compression member 6 is formed to be equal to or larger than the outer diameter of the multi-layer pipe 100.

압착부재(6)는 도시하지 않은 압착 공구를 이용하여 외주면을 균일하게 압착시켜 견고하게 고정되도록 장착된다. The pressing member 6 is mounted so as to firmly press the outer circumferential surface uniformly by using a pressing tool (not shown).

상기 몸체(2)의 외측에 끼워지며 상기 돌출부(4)에 지지되고, 일측에 개구부(22)가 형성되어 압착부재(6)의 단부가 삽입되고, 내주연에 단턱(54)이 형성되어 압착부재(6)의 단부가 지지되는 받침부재(5);를 포함한다. And an opening 22 is formed at one side of the body 2 so that an end of the pressing member 6 is inserted and a step 54 is formed at the inner periphery of the body 2, And a supporting member 5 on which the end of the member 6 is supported.

상기 받침부재(5)의 개구부 내주면에는 압착부재(6)의 단부에 지지되는 지지돌부(52)가 형성된다. A supporting protrusion 52 is formed on an inner circumferential surface of the opening of the receiving member 5 to be supported by the end of the pressing member 6.

한편 도 5를 참조하면, 다른 실시예에 따르면, 압착부재(6)의 일부위를 원호형상으로 절개하되 일부는 남도록 하여 절개편(662)을 형성하고, 상기 절개편(662)이 하방으로 경사지게 절곡시켜 확인공(66')을 형성시킨다. 5, according to another embodiment, a cut piece 662 is formed by cutting a part of the compression member 6 in an arc shape while leaving a part thereof, and the cut piece 662 is inclined downward And then bent to form a confirmation hole 66 '.

따라서 다층관(100)을 압착부재(6)에 끼워넣으면 절개편(662)이 상방으로 펴지면서 확인공(66')을 막게 되므로 확인공(66')이 막힌 상태를 확인함으로써 다층관(100)이 정확한 깊이로 삽입되었는지 인지할 수 있다. Accordingly, when the multi-layer pipe 100 is inserted into the pressing member 6, the discrete piece 662 is expanded upward to close the check hole 66 ', thereby confirming that the check hole 66' ) Is inserted at the correct depth.

한편 도 6을 참조하면, 다른 실시예에 따르면, 압착부재(6)의 내주면에 마찰성과 기밀성을 갖도록 도막층(T)이 형성된다. On the other hand, referring to Fig. 6, according to another embodiment, the coating layer T is formed on the inner peripheral surface of the pressing member 6 so as to have frictional and airtightness.

도막층(T)은 내열 실리콘 소재이며, 소정의 두께로 압착부재(6)의 내주면에 균일하게 형성된다. The coating layer (T) is a heat-resistant silicone material and is uniformly formed on the inner peripheral surface of the pressing member (6) to a predetermined thickness.

따라서 다층관(100)을 삽입하였을때 다층관(100)의 외면에 밀착되어 이탈을 방지하는 마찰력을 제공하게 되고 아울러 기밀성을 갖도록 하여 누설을 방지할 수 있게 된다. Accordingly, when the multi-layer pipe 100 is inserted, it is brought into close contact with the outer surface of the multi-layer pipe 100 to provide a frictional force for preventing the multi-layer pipe 100 from being separated.

한편 도 7을 참조하면, 다른 실시예에 따르면, 압착부재(6)의 내주면에 다수의 돌기로 이루어진 돌기부(S)가 형성된다. 7, according to another embodiment, a plurality of protrusions S are formed on the inner circumferential surface of the pressing member 6.

따라서 다층관(100)을 삽입하였을때 다층관(100)의 외면에 돌기부(S)가 밀착되어 이탈을 방지하는 마찰력을 제공하게 된다. Accordingly, when the multi-layer pipe 100 is inserted, the protrusion S is closely attached to the outer surface of the multi-layer pipe 100 to provide a frictional force for preventing the multi-layer pipe 100 from coming off.

이와 같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Hereinafter, the operation of the present invention will be described.

몸체(2)의 끼움부(28)를 다층관(100)의 내경에 억지끼움으로 가압하여 결합시킨다. The fitting portion 28 of the body 2 is press-fitted to the inner diameter of the multi-layer tube 100 by press fitting.

이후 다층관(100)의 외주면에 압착부재(6)를 삽입한 후 이동시켜 몸체(2)의 끼움부(28)의 외측에 대응되게 밀어 이동한다. Thereafter, the pressing member 6 is inserted into the outer circumferential surface of the multi-layer pipe 100, and the pressing member 6 is pushed and moved corresponding to the outside of the fitting portion 28 of the body 2.

이후 압착부재(6)를 공구를 이용하여 가압시킴으로써 압착부재(6)가 다층관(100)에 압착되어 고정력을 발휘하게 되고, 아울러 오링(27)에 의해 기밀성을 갖게된다.The pressing member 6 is pressed against the multi-layer pipe 100 by using a tool to exert a fixing force, and the ozone 27 has airtightness.

또한 다층관(100)의 피복층에 끼움환턱(26) 및 오링(27), 압착부재(6)가 파고들어가서 견고하게 협착될 수 있는 것이다. The fitting tooth 26, the O-ring 27, and the pressing member 6 are inserted into the covering layer of the multi-layer pipe 100 and can be firmly stuck.

비록 바람직한 실시예와 관련하여 설명되어졌지만, 발명의 요지와 범위로부터 벗어남이 없이 다양한 수정 및 변형이 가능한 것은 당업자라면 용이하게 인식할 수 있을 것이며, 이러한 변경 및 수정은 모두 첨부된 청구의 범위에 속함은 자명하다.It will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, and all such changes and modifications are intended to be within the scope of the appended claims. It is self-evident.
