Description

관 이음 구조{Jointing structure of pipe}Joining structure of pipe

본 고안은 관 이음 구조에 관한 것으로, 특히 관이음 작업 시에 이음부의 밀폐성이 우수하고 관의 이음구조가 견고하도록 하면서도 작업이 간편하도록 하는 관이음 구조에 관한 것이다.The present invention relates to a pipe joint structure, and more particularly, to a pipe joint structure that allows easy operation while making the joint structure of the pipe excellent in sealing performance and making the pipe joint secure.

일반적으로 관은 배관에 의하여 전송되는 유체의 종류, 유량, 온도 등을 고려하여 재료, 강도, 크기 등이 결정되는데, 그 사용목적에 따라서 수도용, 가스용, 압력배관용등으로 나뉘어지고, 그 재질에 따라서 스테인레스관, 강관, 동관등으로 나누어지며 근래에는 PVC관, PE관등 각종 폴리에스테르관이 개발되어 사용되고 있다.In general, the pipe material is determined in consideration of the type, flow rate, temperature, etc. of the fluid transferred by the pipe, depending on the purpose of use, divided into water, gas, pressure piping, etc. According to this, it is divided into stainless steel pipe, steel pipe, copper pipe, etc. Recently, various polyester pipes such as PVC pipe, PE pipe have been developed and used.

상기한 바와 같이 재질에 따라서 분류된 관들 중에서 PE관은 내식성, 내한성, 내약품성이 우수하여 부식이나 전식이 없으며 물성변화가 거의 없을 뿐만 아니라 기타 이물질이 전혀 없고, 강관 또는 연관에 비해 값이 저렴하다는 이점을 지니고 있어 국내 시장에서도 해마다 사용량이 증가하고 있다.Among the pipes classified according to the material as described above, the PE pipe is excellent in corrosion resistance, cold resistance, and chemical resistance, so that there is no corrosion or corrosion, almost no change in physical properties, no other foreign matters, and cheaper than steel pipes or pipes. As a result, the domestic market is increasing year by year.

상기한 바와 같은 PE관을 사용하는데는 목적이나 용도에 따라 나사조임식, 편수칼라식, 열융착식, 전자융착식등의 방법으로 연결되는데, 이중 나사조임식은 관체의 내측과 외측에 암나사와 수나사로된 나선을 구비하여 양측을 조여서 결합하도록 한 것이고, 편수칼라식은 관체의 단부에 부착되어 있는 큰 관부와 상대관체의 단부에 끼운 링을 접속하여 볼트 너트로 조여서 결합하도록 한 것이며, 열융착식은 관체의 이음부를 대향되도록 하고 이를 히터로 가열시킨 후 열융합시켜서 연결되도록 한 것으로 이 열융착식을 이용할 경우에는 값비싼 장비가 있어야 하며 시공시 작업공정이 복잡하며 무거운 장비와 작업공간확보등의 문제점이 있었다. 그리고, 전자융착식은 관체와 관체사이에 전열선이 내재된 이음관을 사용하여 열융합시키는 것으로 관의 내압이 클 경우에 사용되고 있으나, 수평연결 방식에서는 작업이 가능하지만 고층 아파트등 수직으로 관을 연결하는 경우에는 지상에서 조립후 연결된 긴 관체를 세워 연결해야 하는등 관체의 연결작업이 용이하지 않을 뿐 아니라 시공비도 많이 드는 문제점이 있었다.According to the purpose or use, the PE pipe as described above may be connected by a screw fastening method, a single color collar method, a heat welding method, an electronic welding method, etc. The double screw fastening method is a female thread and a male thread on the inside and the outside of the pipe. A screwed spiral is provided to tighten both sides, and the single-collar type is to connect the large pipe part attached to the end of the pipe and the ring fitted to the end of the counterpart pipe, and then tighten it with a bolt nut. It is to be connected to the joints of the heaters and to be connected by heating and heat fusion. When using this heat fusion method, expensive equipment is required, and the work process is complicated during construction, and problems of heavy equipment and work space are secured. there was. In addition, the electronic fusion type is used for heat fusion using a joint tube in which a heating wire is embedded between the tube and the tube. When the internal pressure of the tube is large, it is possible to work in a horizontal connection method but connect the tube vertically such as a high-rise apartment. In this case, there is a problem in that the connection work of the pipe is not easy as well as the construction cost, such as the need to establish a long pipe connected after assembly on the ground.

상기한 바와 같은 문제점을 해결하기 위한 본 고안의 목적은 관의 일측종단에 다른 관이 수용되는 이음관을 일체로 사출성형하고, 상기 이음관에 형성된 복수개의 수용부에는 다수개의 고정편이 관의 삽입방향으로 경사지게 돌출형성된 고정링과 외측 종단측 내주에 관의 외주와 접하는 다수개의 돌기가 환형으로 형성되고 상기 돌기로부터 관의 중심방향으로는 관의 삽입방향으로 경사지게 환형의 봉입편이 돌출형성된 밀폐링을 삽착함으로써, 관이음 작업시에 이음부의 밀폐성이 우수하고 관의 이음구조가 견고하도록 하면서도 작업이 간편하도록 하는 관 이음 구조를 제공함에 있다.An object of the present invention for solving the problems as described above is injection molding integrally the joint pipe which is accommodated in another tube at one end of the tube, a plurality of fixing pieces are inserted into the plurality of receiving portions formed in the joint pipe A fixed ring protruding obliquely in the direction and a plurality of protrusions contacting the outer circumference of the tube on an outer end side inner circumference and having a ring-shaped sealing ring protruding from the protrusion in the direction of insertion of the tube in an inclined direction in the center of the tube. By inserting, it is to provide a pipe joint structure that is excellent in the sealing property of the joint at the time of pipe joint operation, while making the pipe joint structure of the pipe firm and easy to work.

It is inserted into the sealing ring 50 is formed to protrude at an angle oblique.

상기한 바와 같이 구성된 본 고안에 의하면, 소정길이를 갖는 관(10)의 단부에 일체로 사출성형된 이음관(30)내주로 다른 관(20)을 밀착 삽입 끼움 방식으로 끼워서 복수개의 관(10)(20)을 연결하는 것으로, 이에 의하면 관이음시 이음관(30)내로 삽입되는 관(20)이 밀폐링(50)의 돌기(52)를 가압하여 돌기(52)가 관의 진행 방향으로 밀려나게 되고 계속해서 관(20)이 봉입편(54)에 이르게 되면 봉입편(54)종단이 이음관(30)의 내측으로부터 외향으로 밀려나게 되며 이와 같이 원위치로부터 다소 밀려난 돌기(52)와 봉입편(54)은 그 원복력에 의하여 원위치로 회복하려고 하므로 돌기(52)와 봉입편(54)이 관(20)의 외주와 정밀도 있게 접하게 되어 이음관(30)과 삽입되는 관(20)사이에는 기밀을 유지할 수 있게 되고, 관(20)이 계속해서 삽입되면서 고정링(40)에 이르게 되면 고정링(40)에 형성된 다수개의 고정편(42)이 관(20)의 삽입방향으로 다소 밀리게 되고 이에 따라 관(20)의 삽입이 종료되면 고정편(42)은 그 원복력에 의하여 관(20)의 외주를 가압함과 동시에 성형시 관(20)의 삽입방향으로 경사지게 형성되어 있어서 반대방향으로는 휘지 않게 되어 관(20)이 삽입반대방향으로 이탈되는 것이 방지된다.According to the present invention configured as described above, a plurality of pipes (10) by inserting the other pipe (20) in close contact with the inner circumference of the joint pipe 30 integrally injection molded to the end of the pipe (10) having a predetermined length (20) by connecting the tube 20 is inserted into the joint pipe 30 when the pipe joint is pressed by the projection 52 of the sealing ring 50, the projection 52 is in the direction of the tube travel When pushed out and the pipe 20 reaches the encapsulation piece 54, the end of the encapsulation piece 54 is pushed outward from the inside of the joint pipe 30, and thus the protrusion 52 slightly pushed out from its original position. The sealing piece 54 tries to recover to its original position by its restoring force, so that the protrusion 52 and the sealing piece 54 are in exact contact with the outer circumference of the pipe 20 so that the fitting pipe 30 and the pipe 20 are inserted. The airtightness can be maintained in between, and the pipe 20 is continuously inserted into the fixing ring 40 when the fixing ring is reached. When the plurality of fixing pieces 42 formed in the 40 are pushed slightly in the insertion direction of the tube 20, and thus the insertion of the tube 20 is completed, the fixing piece 42 is the tube 20 by its restoring force. At the same time pressing the outer circumference of the) is formed to be inclined in the inserting direction of the tube 20 is not bent in the opposite direction to prevent the tube 20 is separated in the opposite direction of the insertion.

이와 같이 구성된 본 고안에 의하면, 관 이음시 삽입되는 관이 이음관 내부로 완전하게 삽입되었을 때 고정링의 고정편이 삽입된 관의 외주를 견고하게 고정하여 주므로 연결된 관이 분리되는 일이 발생하지 않게 되어 관의 이음구조가 견고하게 되는 효과가 있고, 밀폐링에 의하여 관의 이음부 기밀이 유지되므로 이음부의 밀폐성이 우수하게되는 효과가 있고, 관을 다른 관에 형성된 이음관 내부로 삽입하는 과정만으로 복수개의 관이 상기한 바와 같이 우수한 밀폐성과 견고성을 가지고 결합되므로 관 이음작업이 용이하게 됨과 아울러 관이음작업시에 장비와 시간 및 비용이 절감되는 효과가 있다.According to the present invention configured as described above, when the pipe inserted at the time of pipe fitting is completely inserted into the joint pipe, the fixing piece of the fixing ring firmly fixes the outer circumference of the inserted pipe so that the connected pipe does not occur. It has the effect that the joint structure of the pipe is firm, and the sealing part of the pipe is kept tight by the sealing ring, so the sealing property of the joint is excellent, and only by inserting the pipe into the joint pipe formed in the other pipe. As the plurality of pipes are combined with excellent sealability and robustness as described above, the pipe joint work is facilitated and the equipment, time and cost are reduced during the pipe joint work.
