본 고안은 배관라인 등의 수밀도 체킹을 위한 수압확인장치에 관한 것이다.The present invention relates to a hydraulic pressure checking device for checking the water density of the piping line.

기밀(氣密)이나 수밀(水密)을 요하는 배관라인이나 각종 철구조물은 시공을 완료한 후 적정한 테스팅장치를 이용하여 허용한도 내의 기밀도 혹은 수밀도를 체킹하여야 하고 이를 통과하여야만 한다.Piping lines or various steel structures requiring airtight or watertightness should be checked and passed through airtightness or water density within the allowable limits by means of appropriate testing equipment after completion of construction.

체크를 위한 구분으로서는, 대기압체크와 저압체크 그리고 고압체크로 나뉘어지는데 대기압체크나 저압체크는 배관라인이나 구조물의 내부에 단순히 물을 채워넣거나 혹은 모타펌프를 사용하여 낮은 수압이 작용토록 물을 주입시킨 후 누수부분이 있는지를 확인하는 방법이고, 고압체크는 높은 수압이 작용토록 물을 주입시키는 것이다.The check is divided into atmospheric pressure check, low pressure check, and high pressure check. Atmospheric pressure check or low pressure check can be performed by simply filling water into a pipe line or a structure, or injecting water for low water pressure by using a motor pump. It is a method of checking whether there is a leakage part, and the high pressure check is to inject water so that a high water pressure is applied.

그런데 대기압체크는 대기압이 작용하는 상태에서의 누수확인이므로 실험에 아무런 문제가 없지만 압력이 작용하는 실험에서는 정확하게 작용하는 압력이 얼마인지리를 확인하여야 한다.By the way, the atmospheric pressure check is a leak check in the state of atmospheric pressure, so there is no problem in the experiment, but in the experiment of pressure, it is necessary to confirm the pressure that exactly works.

이 경우 배관라인이나 구조물의 적당한 부분에 압력게이지를 설치하거나 용접으로 취부하여야 하는데 완성된 제품에 구멍을 뚫고 압력게이지를 설치한다는 자체가 합리적이지 못하며 실험후 압력게이지 설치로 인해 손상된 부분을 다시 원상복귀시켜야 하는 불편과 번거로움이 있을 뿐만 아니라 완전한 상태로 복귀시키지 못하는 문제가 있었는데 이를 위한 특별한 장치가 없었기 때문에 상술한 바와 같은 비합리적인 수단을 취하지 않을 수가 없었던 바 본 고안은 상술한 종래 수단의 문제점과 단점을 해결키 위해 안출된 장치이다.In this case, the pressure gauge should be installed or welded on the appropriate part of the pipe line or structure, and it is not reasonable to drill the hole and install the pressure gauge on the finished product. Not only was there inconvenience and hassle to be done, but there was a problem of not being able to return to a complete state. Since there was no special device for this, it was necessary to take irrational means as described above. It is a device designed to solve.

이에 본 고안의 구성을 첨부한 도면에 의해 설명한다.The configuration of the present invention will be described with reference to the accompanying drawings.

연마부(14)를 사이로 좌우에 나사부(13)(15)가 형성되며 너트부(11)에 돌출된 나사부(12)가 형성되고 내부는 통공(16)인 부품지지관(10)에 너트(20)와 부싱(30), 조(40), 테이퍼관(60), 부싱(70) 및 통공(81)이 형성된 고무관(80)과 부싱(90) 및 너트(100)를 순서대로 조립시키되, 상기한 조(40)는 고무관(80)의 반대쪽으로 상향경사가 지는 이빨(41)이 형성되면서 4-8조각으로 원주상 균등분할이 되도록 하여 오-링(50)으로 그리핑되도록 하고 테이퍼관(60)과 부싱(70), 고무관(80)은 연마부(14) 상에 위치토록 하여서; 조(40)와 고무관(80)이 테스팅파이프(700) 안으로 삽입되게 한 후 너트부(11)를 고정시키고 너트(20)를 조이면 조(40)가 테이퍼관(60)의 경사면을 타고 올라가 부싱(70)을 밀고 부싱(70)은 고무관(80)을 강하게 조여서 직경이 확장되게 함으로서 결국 고무관(80)과 조(40)의 원주면이 테스팅파이프(700)의 내면에 강하게 밀착되어 빠져나오지 못하도록 함으로서 부품지지관(10)의 통공(16)을 통해 전달되는 압력은 나사부(12)에 조립되어 있는 압력게이지(500)를 작동시킬 수 있도록 함이 특징인 본 고안은, 상술한 바와 같이 조(40)와 고무관(80)이 테스팅파이프(700) 안으로 들어가도록 한 뒤 너트(20)를 조여 사용하는데 테스팅파이프(700)는 배관라인의 일단이나 구조물에 설치되어 있는 관체를 말한다.Threads 13 and 15 are formed on the left and right sides of the grinding part 14, and threaded parts 12 protruding from the nut part 11 are formed, and the nut is inserted into the part support tube 10, which is a through hole 16. 20 and the bushing 30, jaw 40, taper pipe 60, bushing 70 and the rubber tube 80, the bushing 90 and the nut 100, the through hole 81 is formed in order, The jaw (40) is formed to be the inclined evenly divided into 4-8 pieces while the teeth (41) forming the inclined upward to the opposite side of the rubber tube (80) to be gripped by the O-ring (50) and tapered pipe The 60, the bushing 70, and the rubber tube 80 to be positioned on the polishing portion 14; After the jaw 40 and the rubber tube 80 are inserted into the testing pipe 700, the nut part 11 is fixed and the nut 20 is tightened. The jaw 40 climbs up the inclined surface of the tapered pipe 60 to bush the bushing. Push the 70 and the bushing 70 to tighten the rubber tube 80 so that the diameter is expanded so that the circumferential surfaces of the rubber tube 80 and the jaw 40 is in close contact with the inner surface of the testing pipe 700 so as not to escape. The present invention is characterized in that the pressure transmitted through the through hole 16 of the component support pipe 10 can operate the pressure gauge 500 assembled to the threaded portion 12, as described above, 40) and the rubber pipe 80 is used to tighten the nut 20 after entering the testing pipe 700, the testing pipe 700 refers to the pipe is installed on one end or structure of the pipe line.

상술한 바와 같이 본 고안을 테스팅파이프(700) 안에 위치시킨 후 너트부(11)를 스패너 등으로 고정시킨 뒤 너트(20)를 조이면 부싱(30)이 조(40)를 밀고 조(40)는 테이퍼관(60)의 경사를 타고 확장되면서 상승이동을 한다.As described above, after the present invention is placed in the testing pipe 700, the nut part 11 is fixed with a spanner, and the nut 20 is tightened. The bushing 30 pushes the jaw 40 and the jaw 40 The tapered pipe 60 is moved up and down while inclined.

이때 오-링(50)은 4-8조각으로 균등분할되어 있는 조(Jaw)들이 흐트러지지 않도록 그리핑(Gripping)하여 주는 역할을 하며 조임동작이 종료되었을 때에는 고무관(80)과 함께 수밀작용을 하는 2중의 중요기능을 가진다.At this time, the O-ring 50 serves to gripping the jaws that are equally divided into 4-8 pieces so as not to be disturbed, and when the tightening operation is completed, the O-ring 50 performs a watertight action together with the rubber tube 80. It has two important functions.

조(40)가 계속 이동을 하면 부싱(70)을 밀게 되는데 부싱(70)은 고무관(80)을 강하게 조여 고무관(80)의 직경을 팽창시키게 되는데 더욱 강하게 팽창시키고저 하면 너트(20)를 계속하여 조여주면 되지만 고무관(80)의 탄성한계가 있어 무리한 조임작용이 가해질 수는 없다.If the jaw 40 continues to move, it pushes the bushing 70. The bushing 70 tightly tightens the rubber tube 80 to expand the diameter of the rubber tube 80. If the tube 40 is expanded more strongly, the nut 20 continues. It may be tightened, but there is an elastic limit of the rubber tube 80, so that an unreasonable tightening action cannot be applied.

이 상태는 고무관(80)의 확장된 원주면이 테스팅파이프(700)의 내면에 강하게 끼이게 됨과 동시에 확장된 조(40)의 이빨(41)은 테스팅파이프(700) 내부에 작용하는 압력에 의해 약간 후진하면서 테스팅파이프의 내면에 박히게 된다.In this state, the expanded circumferential surface of the rubber tube 80 is strongly sandwiched by the inner surface of the testing pipe 700, and at the same time, the teeth 41 of the expanded jaw 40 are driven by the pressure acting inside the testing pipe 700. Slightly retracted and lodged inside the testing pipe.

따라서 조(40)는 더 이상 후진하지 않게 되면서 제 위치를 고수하게 되며 오-링(50)은 고무관(80)과 함께 수밀역할을 한다.Therefore, the jaw 40 is no longer backed up and held in place and the O-ring 50 plays a watertight role together with the rubber tube 80.

실험예에 의하면 테스팅파이프(700)의 직경이 1inch인 상태에서 본 고안을 조립하였을 때 테스팅파이프 내부에 작용하는 압력이 50Kg/㎠에 달하여도 본 고안의 작용에는 아무런 문제가 없었다.According to the experimental example, when the present invention is assembled in a state in which the diameter of the testing pipe 700 is 1 inch, the working pressure of the present invention reaches 50Kg / cm 2, but there is no problem in the present invention.

본 고안이 테스팅파이프(700) 내부에 상기한 바와 같이 조립되면 적정한 장치를 이용하여 물 또는 오일을 배관라인 내부 혹은 구조물의 내부로 주입시키면서 압력을 가하게 되는데 이때 작용하는 압력은 부품지지관(10)의 통공(16)을 통해 나사부(12)에 조립되어 있는 압력게이지(500)를 작동시키게 되며 정확한 작용압력을 관찰할 수 있는 것이다.When the present invention is assembled as described above in the testing pipe 700, the pressure is applied while injecting water or oil into the pipe line or the inside of the structure by using a suitable device. Through the hole 16 to operate the pressure gauge 500 is assembled to the threaded portion 12 will be able to observe the correct working pressure.

따라서 본 고안을 사용하면 배관라인이나 구조물에 압력게이지를 번거로이 설치하지 않고 매우 간단하며 편리하게 또한 신속하고 정확하게 테스팅압을 체킹할 수 있는 효과가 있다.Therefore, if the present invention is used, it is possible to check the testing pressure very simply, conveniently, and quickly and accurately without the need to install pressure gauges in piping lines or structures.
