본 고안은 관체를 접속 연결함에 있어서, 이음관의 내부 양쪽 환상돌턱과 외벽 사이에 공간부에 외향진 환형돌기를 형성한 패킹의 돌테를 끼워 넣고 패킹 삽지부내에는 관체를 삽입하여 외측에서 드라이버로 결착밴드를 조여서 압착되게 함으로써 내부 압력이나 외부 압력에 영향됨이 없이 패킹에 의한 긴밀성으로 완벽한 수밀을 기할 수 있게한 관 이음쇠에 관한 것이다.The present invention connects the tubular body, between the annular projections and the outer wall of the joint pipe and inserts the dolce of the packing that forms an outward annular projection in the space portion, and inserts the tubular body in the packing inserting part to the driver from the outside The present invention relates to a pipe fitting which is tightened by tightening a binding band to achieve perfect water tightness by tightness of packing without being affected by internal pressure or external pressure.
종래의 통상적인 관 이음방식으로는 관체의 일판에 플렌지부를 형성하여 플랜지부에 상대편의 관체를 연결시에 밀폐용 패킹을 삽설되게 하거나, 또다른 방식으로는 관체의 양단에 플랜지부를 형성하여 플랜지부를 서로 접합시에 그 사이에 밀폐용 패킹을 삽설되게 한 것으로 이들 방식은 모두 패킹을 삽설하는데 정확성과 많은 힘을 필요로 하는 반면에 시공후의 사용시에는 내부를 흐르는 유체의 압력이 적을때는 수밀의 효과를 기대할 수 있지만 유체의 압력이 크거나 특히 수중에서와 같이 외부의 압력이 클때에는 긴밀성을 유지하는데 문제점이 있었다.In a conventional pipe joint method, a flange is formed on one plate of a pipe to allow a sealing packing to be inserted at the time of connecting the other pipe to the flange, or in another way, a flange is formed on both ends of the pipe. When the joints are joined together, sealing packings are inserted between them. All of these methods require accuracy and a lot of force to insert the packings. The effect can be expected, but there is a problem in maintaining the tightness when the pressure of the fluid is large or the external pressure is large, especially in water.
본 고안은 상기와 같은 종래의 문제점을 감안하여 시공후에는 내외부의 압력에 관계없이 긴밀성을 유지할수 있을 뿐 아니라 관체의 접속 연결작업은 숙련공이 아니더라도 간단히 수행할 수 있게 안출한 것으로서, 그 요지를 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention is not only able to maintain the tightness regardless of the internal and external pressure after construction in view of the above-mentioned conventional problems, but also to connect the connection of the tubular body can be easily performed even without skilled workers, attached to the gist When described in detail based on one drawing is as follows.
외주면 양쪽에 조임구멍(1)(1')이 형성된 이음관(3) 내부 양쪽에 받침턱(3a)(3b)과 환상 돌턱(4)(4')이 형성되어 외벽(5)(5')사이에 공간부(6)(6')를 형성하고 이에 환형동기(7)(7')가 돌설된 패킹(8) 외주의 돌테(9)가 끼워지며 패킹(8)의 삽지부(10) 외주면에서 결착밴드(12)를 끼워 조임구멍(1)(1')의 내측상에 위치시켜 패킹(8) 내에 끼워 넣은 공지의 관체(11)(11')를 조임구멍(1)(1')를 통해 결착밴드(12)를 조임으로써 긴밀하게 압착되게 구성한 것이다.Supporting jaws 3a and 3b and annular projections 4 and 4 'are formed on both sides of the joint pipe 3 with the tightening holes 1 and 1' formed on both outer circumferential surfaces thereof. Cavities (9) of the outer periphery of the packing (8) with the annular synchronous (7) (7 ') formed therebetween, and the insertion part (10) of the packing (8). The well-known tubular body 11 (11 ') inserted in the packing 8 by inserting the binding band 12 in the outer peripheral surface and being located on the inner side of the tightening hole 1, 1' is tightened in the tightening hole 1 (1). By tightening the binding band 12 through ') is configured to be tightly compressed.
도면중 미설명 부호 2, 2'는 밀폐용 볼트, 13은 조임나사이다.In the drawings, reference numerals 2 and 2 'are sealing bolts, and 13 are tightening screws.
이와 같이 구성된 본 고안을 실시함에 있어서, 탄성이 부여된 패킹(8)의 삽지부(10) 외주면상의 결착밴드(12)가 이음관(3) 양쪽의 입구로 삽입할 수 있는 정도의 직경이 되도록 조임나사(13)를 조인 다음, 삽지부(10)가 내향되도록 양쪽에서 삽입시키되 환상 돌턱(4)(4')과 외벽(5)(5') 사이의 공간부(6)(6') 내에 패킹(8)의 돌테(9)가 끼워질 수 있도록 이음관(3) 양쪽의 입구로 삽입시킬 수 있을 정도로 패킹(8)을 압축시켜 이음관(3)내로 삽입하면 외향진 환형돌기(7)(7')가 공간부(6)(6')내의 벽면에 압접되어 긴밀상태를 유지하게되고, 이음관(3) 외주면 양쪽의 조임구멍(1)(1')을 통하여 외측에서 드라이브의 공구를 사용하여 걸착밴드(12)를 확장시키면 삽지부(10)가 조임전의 원상태로 환원되게 된다.In carrying out the present invention configured as described above, the binding band 12 on the outer circumferential surface of the inserting portion 10 of the packing 8 to which the elasticity is applied is such that the diameter can be inserted into the inlet of both of the joint pipes 3. Tighten the captive screw 13, and then insert the insert 10 from both sides so that the insert 10 is inward, but the space 6, 6 'between the annular projection 4, 4' and the outer wall 5, 5 '. When the packing 8 is compressed and inserted into the joint pipe 3 so that the dowel 9 of the packing 8 can be inserted into the inlet on both sides of the joint pipe 3, the outward annular projection 7 7 'is pressed against the wall in the spaces 6 and 6' to maintain the tight state, and through the fastening holes 1 and 1 'on both outer peripheral surfaces of the joint pipe 3, When the mounting band 12 is expanded by using a tool, the inserting portion 10 is reduced to its original state before tightening.
이상과 같은 조립 방법으로 이음관(3)의 내부 양쪽에 패킹(8)이 긴밀하게 끼워지면 양쪽에서 삽지부(10)내로 관체(11)(11')를 삽입한 후 조입구멍(1)(1')을 통하여 드라이브등의 공구로 조임나사(13)를 조여서 삽지부(10)의 내면과 관체(11)(11')의 외주면이 밀착되게 한다.If the packing 8 is tightly fitted to both insides of the joint pipe 3 by the above-described assembly method, the pipe bodies 11 and 11 'are inserted into the inserting portion 10 from both sides, and then the insertion holes 1 ( Tighten the tightening screw 13 with a tool such as a drive through 1 ') to bring the inner surface of the inserting portion 10 into close contact with the outer circumferential surface of the tubular bodies 11 and 11'.
조임나사(13)을 조일때에 밀면서 조이더라도 조임나사(13)의 후단을 받침턱(3a)(3b)이 받치게 되어 결착밴드(12)의 돌아감이 방지된다.Even if the tightening screw 13 is pushed while tightening, the supporting jaw 3a, 3b supports the rear end of the tightening screw 13, thereby preventing the binding band 12 from turning.
조임작업이 끝나면 조임구멍(1)(1')에 밀폐용 보울트(2)(2')를 나착하게 되면 관체(11)(11')의 접속 연결작업이 완료되며, 이러한 상태에서는 관체(11)(11') 외주면은 패킹(8)의 삽지부(10) 내면과의 견고한 접면으로 긴밀 상태를 유지함을 물론 패킹(8)의 돌테(9)가 공간부(6)(6')에 긴밀하게 삽입되어 양쪽의 환형돌기(7)(7')가 벽면에 압접되어 있으므로 관체(11)(11') 내부의 유체의 흐름에 의하여 압력이 걸치게 되면, 오히려 환상 돌턱(4)(4')에 접면한 환혀돌기(7)은 절결부에 미치는 압력으로 더욱 압접되며 외부의 압력이 패킹(8)에 미치더라도 역시 환형돌기(7')가 외벽(5)(5')의 내면에 압접되므로서 내외부의 압력에 관게 없이 긴밀성을 유지하여 수밀의 효과를 높일 수 있는 것이다.After the tightening operation, if the bolts for sealing (2) (2 ') are attached to the tightening holes (1) (1'), the connection and connection work of the tubular bodies (11) and (11 ') are completed, and in this state, the tubular bodies (11) The outer circumferential surface of 11) maintains a tight contact with the inner surface of the inserting portion 10 of the packing 8, as well as the dolme 9 of the packing 8 is tightly connected to the space 6, 6 '. Since both annular projections 7 and 7 'are press-contacted to the wall, when pressure is applied by the flow of the fluid inside the tube body 11 and 11', the annular projection 4 and 4 ' The annular projections (7), which are in contact with the c), are further pressed by the pressure applied to the cutouts, and the annular projections (7 ') are pressed against the inner surfaces of the outer walls (5) (5') even when the external pressure is applied to the packing (8). Therefore, it is possible to increase the effect of watertightness by maintaining the tightness irrespective of the internal and external pressure.
