본 고안은 배관 연결장치에 관한 것으로 특히, 내부에 고압이 가해지고 기밀을 유지하는데 적당하도록 한 것이다.The present invention relates to a pipe connecting device, in particular, to be suitable for maintaining a high pressure inside the airtight.

종래의 배관 연결구조는 제3도의 (a)에서와 같이 직경이 상이하여 서로 삽입이 용이한 배관(21, 22)의 경우에는 모재를 녹여서 용접하고, (b)도에서와 같이 두 개의 배관(23, 24)삽입이 곤란한 경우에는 한쪽 배관(24)을 넓혀서 용접하거나 또는 (c)도에서와 같이 연결튜브(25)을 사용하여 용접하고 있다.In the conventional pipe connection structure, as shown in (a) of FIG. 3, the pipes 21 and 22 having different diameters and easily inserted into each other are melted and welded with a base material, and as shown in (b), two pipes ( 23, 24) When it is difficult to insert, one pipe 24 is widened and welded, or as shown in (c), it is welded using a connecting tube 25.

그러나, 이와 같은 종래의 배관 연결구조에 의하면 용접 작업시에 발생된 이물질이 배관(21, 22, 23, 24)내부를 유동되게 되므로 모세관이나 또는 압축기등에 적용된 제품의 경우 유로를 폐쇄하게 되며 압축기 내부를 손상시키는 문제점이 있고 또한 융점의 차이가 큰 재질로 된 배관의 경우 용접하기가 어렵게 되며 용접부위의 강도 불량으로 인하여 배관 내부에 장시간 고압이 가해지는 경우 배관 내부의 유체(예 : 냉매)가 누설되는 문제점이 있었다.However, according to the conventional pipe connection structure, foreign substances generated during welding work flow inside the pipes 21, 22, 23, and 24, so that the flow path is closed in the case of a product applied to a capillary tube or a compressor, etc. In the case of pipes made of materials with high melting point and difficult to weld, it is difficult to weld and fluid (eg refrigerant) inside the pipe leaks when high pressure is applied to the pipe for a long time due to poor strength of the welded part. There was a problem.

본 고안은 이와 같은 종래의 문제점을 해결하기 위하여 용접작업을 배제하고 조임링과 연결튜브를 이용하여 용이하게 배관 연결작업을 할 수 있도록 함으로써 유로가 폐쇄되거나 제품 내부를 손상시키는 현상을 방지하고 작업성 향상을 기하며 배관의 기밀성을 유지하여 유체 누설을 방지할 수 있도록 한 배관 연결장치를 제공하는데 그 목적이 있는 것으로, 첨부된 도면에 의하여 본 고안의 구성 및 작용효과를 상세히 설명하면 다음과 같다.The present invention eliminates the welding work in order to solve such a conventional problem, it is possible to easily connect the pipe by using the fastening ring and the connection tube to prevent the phenomenon that the flow path is closed or damage the inside of the product and workability The purpose of the present invention is to provide a pipe connecting device for improving fluidity and preventing fluid leakage by maintaining airtightness of a pipe. The configuration and effect of the present invention will be described in detail with reference to the accompanying drawings.

우선 제1도 및 제2도를 참조하여 본 고안의 구성부터 설명하면, 배관(1, 2) 단부가 양측 구멍으로부터 내부로 삽입되어 양측배관(1, 2)을 연결하는 연결튜브(3)와, 상기 연결튜브(3)의 외주면에 형성되며 조임링(4, 5)의 대향면(4', 5')이 밀착되어 제동되는 외부 제동테(6)와, 상기 연결튜브(3)의 내주면에 형성되며 배관(1, 2)의 두께 (t1)와 동일한 두께(t2)를 유지하고 배관(1, 2)의 대향면(1', 2')이 밀착되어 제동되는 내부 제동테(7)와, 배관(1, 2) 외주면과 연결튜브(3)의 외주면을 감싸고 가압시켜 밀봉시키는 조임링(4, 5)과, 상기 조임링(4, 5)내면의 전, 후방에 각각 다른 내경을 유지하며 배관(1, 2) 외면을 가압하는 전방 테이퍼면(8, 9) 및 후방테이퍼면(8', 9')으로 구성된다.First, referring to the configuration of the present invention with reference to Figures 1 and 2, the end of the pipe (1, 2) is inserted into the interior from both holes and the connecting tube (3) for connecting the two pipes (1, 2) and , An outer braking frame 6 formed on an outer circumferential surface of the connection tube 3, and the opposite surfaces 4 ′ and 5 ′ of the tightening rings 4 and 5 are in close contact with each other, and an inner circumferential surface of the connection tube 3. An internal braking frame which is formed in and maintains the thickness t 2 equal to the thickness t 1 of the pipes 1 and 2, and the opposite surfaces 1 ′ and 2 ′ of the pipes 1 and 2 are in close contact with each other. 7), the fastening rings (4, 5) surrounding the outer peripheral surface of the pipe (1, 2) and the outer peripheral surface of the connecting tube (3) and pressurized to seal, and the front and rear of the inner surface of the tightening rings (4, 5), respectively It consists of a front tapered surface 8, 9 and a rear tapered surface 8 ', 9', which pressurizes the outer surface of the pipes 1, 2 while maintaining the inner diameter.

도면중 미설명 부호 10은 테이퍼면(8, 8', 9, 9')에 의하여 배관(1, 2)의 외경이 감소된 부분이다.In the figure, reference numeral 10 denotes a portion where the outer diameters of the pipes 1 and 2 are reduced by the tapered surfaces 8, 8 ', 9 and 9'.

이와 같이 구성된 본 고안의 작용효과는 제1도 및 제2도에서와 같이 배관(1, 2)을 연결하는 경우에는 먼저 배관(1, 2) 외주면에 연결튜브(3)속에 삽입될 길이만큼 접착제를 도모한다.The effect of the present invention configured as described above is that when connecting the pipes (1, 2), as shown in Figures 1 and 2 first, the length of the adhesive to be inserted into the connecting tube (3) to the outer peripheral surface of the pipes (1, 2) Promote.

이 접착제는 배관(1, 2) 표면에 도포되어 표면상태에 관계없이 양호한 기밀을 유지시키기 위한 것으로 퍼짐성이 양호한 시일용 접착제를 사용한다.This adhesive is applied to the surfaces of the pipes 1 and 2 so as to maintain good airtightness regardless of the surface condition and uses a sealing adhesive having good spreadability.

이어서 배관(1, 2)의 대향면(1', 2')을 조임링(4, 5)을 관통시켜 연결튜브(3)속에 삽입시키면 대향면(1', 2')이 연결튜브(3)의 내부 제동테(7)에 걸려서 정지된다.Subsequently, the opposing surfaces 1 'and 2' of the pipes 1 and 2 are inserted into the connecting tube 3 through the tightening rings 4 and 5 so that the opposing surfaces 1 'and 2' are connected to the connecting tube 3. ) Is caught by the inner braking frame (7).

이 내부제동테(7)의 두께(t2)는 배관(1, 2)의 두께(t1)와 동일하므로 대향면(1', 2')이 내부제동테(7)에 밀착되어 기밀이 유지된다.Since the thickness t 2 of the internal brake frame 7 is the same as the thickness t 1 of the pipes 1 and 2, the opposing surfaces 1 ′ and 2 ′ are in close contact with the internal brake frame 7 so that airtightness is maintained. maintain.

이어서 조임링(4, 5)의 대향면(4', 5')을 연결튜브(3)의 외부제동테(6)에 밀착시키면 조임링(4, 5)이 각각 배관(1, 2)의 연결지점(내부 제동테(7) 부분)으로 부터 동일한 거리로 위치되면서 배관(1, 2)을 포함하여 연결튜브(3)를 균일하게 감싸게 된다.Subsequently, the opposing surfaces 4 'and 5' of the tightening rings 4 and 5 are brought into close contact with the external braking frame 6 of the connecting tube 3, and the tightening rings 4 and 5 are respectively connected to the pipes 1 and 2, respectively. It is positioned at the same distance from the connection point (inner braking frame (7) portion) to uniformly wrap the connecting tube (3) including the pipe (1, 2).

이어서 조임링(4, 5)의 외주면에 강한 압력을 가하게 되면 조임링(4, 5)의 전방테이퍼면(8, 9)이 연결튜브(3) 외주면을 가압하면서 그 외경을 감소시키므로 연결튜브(3) 내관과 배관(1, 2) 외면 사이에 탄성압력이 가해지게 되어 연결튜브(3) 내면과 배관(1, 2) 외면이 밀착되고 또한 조임링(4, 5)의 후방테이퍼면(8', 9')이 연결튜브(3)의 외주면을 가압하여 그 외경을 감소시키므로 결국 연결튜브(3) 내면과 배관(1, 2) 외면은 견고하게 밀봉되어 연결된다.Subsequently, when a strong pressure is applied to the outer circumferential surfaces of the tightening rings 4 and 5, the front tapered surfaces 8 and 9 of the tightening rings 4 and 5 press the outer circumferential surface of the connecting tube 3 to reduce the outer diameter thereof, thereby connecting the connecting tube ( 3) An elastic pressure is applied between the inner tube and the outer surface of the pipes 1 and 2 so that the inner surface of the connecting tube 3 and the outer surface of the pipes 1 and 2 are in close contact and the rear tapered surface of the tightening rings 4 and 5 (8). ', 9' presses the outer circumferential surface of the connecting tube 3 to reduce its outer diameter, so that the inner surface of the connecting tube 3 and the outer surfaces of the pipes 1 and 2 are tightly sealed.

따라서 배관(1, 2)의 연결부위에는 여러단계로 외경이 감소된 부분(10)이 발생되고 이 부분에서의 배관(1, 2) 및 연결튜브(3) 상호간의 탄성압력에 의한 기밀유지가 이루어진다.Therefore, the connection part of the pipes (1, 2) generates a portion 10 having an outer diameter reduced in several stages, and the airtightness is maintained by the elastic pressure between the pipes (1, 2) and the connection tube (3) in this part. Is done.

이상에서 설명한 바와 같이 본 고안에 의하면 배관 연결작업이 용이하여 작업성 향상을 도모할 수 있고 배관 내부의 고압 환경에서도 기밀유지가 되므로 제품의 품질과 신뢰성을 높일 수 있으며 융점의 차이가 큰 배관이나 직경이 다른 배관의 연결 작업을 편리하게 행할 수 있는 효과가 있다.As described above, according to the present invention, it is easy to connect the pipes to improve the workability, and it is possible to maintain the airtightness even in the high pressure environment inside the pipes, so that the quality and reliability of the product can be improved. There is an effect that the work of connecting other pipes can be conveniently performed.
