본 고안은 주로 시설전후에 상, 하수관 가스파이프라인과 같은 유체관(流體管)의 누출부를 검출해내기 위하여 연결된 파이프의 개구부를 밀폐시킬 수 있도록된 밀폐기에 관한 것이다.The present invention mainly relates to a sealer capable of sealing an opening of a connected pipe in order to detect leaks in a fluid pipe such as a water pipe and a sewage pipe gas pipeline before and after a facility.

종래에 있어서 관의 누출을 검사하기 위해서는 관의 직경보다 약간 작은 원판 외주면에 탄성재의 테를 둘러 관의 개구를 틀어막는 정도의 불실한 작업으로 관의 밀폐가 행해졌기 때문에 작업상의 어려움은 물론 기대할만한 확고한 밀폐효과를 보장할 수 없었던 것이다.Conventionally, in order to inspect the leak of the tube, the sealing of the tube was performed by the unstable work of closing the opening of the tube by surrounding the edge of the elastic material on the outer circumferential surface of the disc slightly smaller than the diameter of the tube. It could not guarantee a firm sealing effect.

본 고안은 상기한 문제점들을 해결할 목적으로 사람의 힘에 의해 관의 개구부를 밀폐시키기 위해 수로공을 가진 축의 일단에 환상의 테이퍼면을 갖는 제1디스크를 고정설치하여 이 축에 관의 밀폐를 위한 링(ring)형상의 고무체링과, 테이퍼면이 대칭적으로 형성된 기준 디스크에 이어 상기한 동일형의 고무체링을 다시 제1디스크 모양과 동일한 제2디스크를 순차로 삽입시켜 축의 타단에 결합된 조임 너트를 돌려 제1디스크와 제2디스크로 하여금 기준디스크 양측에 개재된 고무체링을 압압하여 양측 디스크의 테이퍼면이 고무체 링의 수로 공으로 삽입하면서 고무체 링의 내외경을 증가함으로 고무체 링의 외경부의 주면이 관의 내주면을 밀착시켜 밀폐되는 것을 특징으로한 것이다.The present invention is intended to solve the above problems by fixing the first disk having an annular tapered surface at one end of the shaft having a waterway hole to seal the opening of the tube by human force for sealing the tube on this shaft. After the ring-shaped rubber ring and the reference disk with the tapered surface symmetrically formed, the same rubber ring is inserted again and the second disk having the same shape as the first disk is sequentially inserted and tightened to the other end of the shaft. Turn the nut to force the first disk and the second disk to press the rubber ring interposed on both sides of the reference disk so that the tapered surface of both disks is inserted into the ball of the rubber ring to increase the inner and outer diameters of the rubber ring. The outer surface of the outer diameter portion is characterized in that the inner circumferential surface of the tube is in close contact and sealed.

그러므로 본 고안은 조임너트의 나사힘을 이용하여 관을 밀폐시킬 수 있게한 것으로서 이를 첨부된 도면에 의거 상세히 설명하면 중앙부에 수로(水路)(1P)가 형성된 축(1)의 일단에 외주면으로 부터 경사진 테이퍼면(2T)을 가진 제1디스크(2)를 나착 고정하여 이 테이퍼면(2T)에 고무체링(3)의 내경부에 근접한 만곡면(3C)이 당접되도록 고무체링(3)의 내경부를 형성하고, 이 고무체링(3)(3')사이에 개재되는 기준 디스크(4)에는 외주면으로부터 경사진 대칭형의 테이퍼면(4T)(4T')를 형성하여 상기한 기준 디스크(4)의 테이퍼면(4T)(4T')에 당접된 고무체링(3)(3')의 만곡면(3C)(3C')을 제1디스크(2) 및 제2디스크(5)의 테이퍼면(2T)(5T')이 기준 디스크(4)에 대해 압압함으로 고무체링(3)(3')의 내외경이 증대되면서 관의 내주면을 밀폐시킨다. 이 압압력은 축의 나선부에 조임너트(6)를 스페이서(7)에 대항하여 돌려 조일때 발생한다. 8은 핸들이고 9는 축(1)의 수로(1P)를 개폐하는 밸브이다.Therefore, the present invention allows the tube to be sealed by using the screwing force of the fastening nut, which will be described in detail with reference to the accompanying drawings. From the outer peripheral surface at one end of the shaft 1 in which the water channel 1P is formed in the center, Of the rubber ring 3 so that the first disk 2 having the inclined taper surface 2T is screwed and fixed so that the curved surface 3C close to the inner diameter of the rubber ring ring 3 abuts the tapered surface 2T. An inner diameter portion is formed, and on the reference disk 4 interposed between the rubber ring rings 3 and 3 ', a symmetrical tapered surface 4T and 4T' inclined from the outer circumferential surface is formed, so that the reference disk 4 is formed. The curved surface 3C (3C ') of the rubber ring ring 3 (3') abutting the tapered surface 4T (4T ') of the tapered surface of the first disk 2 and the second disk 5 (2T) 5T 'presses against the reference disk 4 to increase the inner and outer diameters of the rubber ring rings 3 and 3', thereby sealing the inner circumferential surface of the tube. This pressing force is generated when the tightening nut 6 is turned against the spacer 7 in the spiral part of the shaft. 8 is a handle and 9 is a valve which opens and closes the channel 1P of the shaft 1.

이와같이 구성된 본 고안의 밀폐기를 제2도에 나타낸 바와같이 밀폐하려는 관의 개구부에 삽입하여 핸들(8)을 나사조임 방향으로 돌리면 축(1)의 일단에 고정된 제1디스크(2)와 축(1)에서의 이동가능한 제2디스크(5)는 역시 축(1)에서 이동가능한 기준디스크의 테이퍼면(4T)(4T')에 당접개재된 고무체링(3)(3')의 타방 만곡면을 각각 압압함으로 고무체링(3)(3')을 관의 내주면으로 밀어 붙이게 되어 밀폐된다.As shown in FIG. 2, when the sealer of the present invention configured as described above is inserted into the opening of the tube to be sealed and the handle 8 is turned in the screw tightening direction, the first disk 2 and the shaft ( The second movable disk 5 in 1) is also the other curved surface of the rubber ring 3, 3 'abutting the tapered surfaces 4T, 4T' of the reference disk movable in the shaft 1. By pressing each of the rubber ring (3) (3 ') is pushed to the inner peripheral surface of the pipe is sealed.

그러므로 본 고안은 축의 일단에 제1디스크를 고정하여 이 축에 고무체링, 기준 디스크, 고무체링 및 제2디스크등을 순차적으로 삽입하고, 상기한 디스크에는 외주면으로부터 경사진 테이퍼면을 형성하는 한편 고무체링의 내경부로부터 만곡면을 형성하여 제1디스크 및 제2디스크의 테이퍼면으로 고무체링의 만곡면을 압압시켜 관을 밀폐시키는 것으로서 스크류의 조임력을 이용하여 인력에 의해 강력한 밀폐 효과를 얻게한 것이다.Therefore, the present invention secures the first disk to one end of the shaft and inserts the rubber ring, the reference disk, the rubber ring and the second disk in this axis in sequence, and the disk has a tapered surface inclined from the outer circumferential surface. A curved surface is formed from the inner diameter of the chering, and the curved surface of the rubber chering is pressed to the tapered surfaces of the first disc and the second disc to seal the pipe. A strong sealing effect is obtained by the attraction force using the screw tightening force. .

또한 본 고안의 밀폐기는 제3도와 같이 관을 밀폐시켜 축(1)의 수로(1P)를 통해 물을 주입시킨후 밸브(9)를 닫아 충진된 시험수In addition, the sealer of the present invention seals the tube as shown in FIG. 3, injects water through the channel 1P of the shaft 1, and then closes the valve 9 to fill the test water.
