The female screw portion 11 is formed on the inner circumferential surface to be screwed to the male screw portion 21.

즉, 도 1 및 도 2에서는 상기 제1부재(10)를 관(파이프)으로 도시하였고, 상기 제2부재(20)는 니플로 도시하였지만, 상기 제2부재(20)는 관도 될수 있고 밸브도 될 수 있다. 이때 중요한것은 상기 제2부재(20)에 상기 제1부재(10)의 단부가 걸리도록 돌출부(22)가 확장형성되어 있어야 한다.That is, in FIG. 1 and FIG. 2, the first member 10 is illustrated as a pipe, and the second member 20 is illustrated as a nipple. However, the second member 20 may be a tube or a valve. Can be. At this time, it is important that the protrusion 22 is extended so that the end of the first member 10 is caught by the second member 20.

한편, 도 1 및 도 2를 잠깐 설명하면, 상기 제2부재(니플)(20)의 돌출부(22) 양측 외주면에 수나사부(21)가 형성된다. 이때 상기 제2부재(니플)(20)의 일측 수나사부(21)에는 아래에서 설명될 패킹하우징(30) 및 패킹부재(40)를 끼운 상태에서 상기 제1부재(파이프)(10)의 암나사부(11)가 나사결합되고, 상기 제2부재(니플)(20)의 타측 수나사부(21)에는 다른 연결파이프(50)가 너트(60)를 매개로 결합된다.1 and 2, male threads 21 are formed on the outer circumferential surfaces of both sides of the protrusions 22 of the second member (nipple) 20. At this time, the female screw of the first member (pipe) 10 in a state in which the packing housing 30 and the packing member 40 which will be described below are inserted into one male screw portion 21 of the second member (nipple) 20. The part 11 is screwed, and the other connecting pipe 50 is coupled to the other male screw part 21 of the second member (nipple) 20 via the nut 60.

또한, 상기 제1부재(10)와 제2부재(20)의 나사결합시 기밀/수밀을 유지할 수 있도록 상기 제1부재(10)의 단부와 상기 제2부재(20)의 돌출부(22) 사이에 오링 등과 같은 패킹부재(40)가 설치된다.In addition, between the end of the first member 10 and the protrusion 22 of the second member 20 to maintain the airtight / watertight when the first member 10 and the second member 20 is screwed The packing member 40 such as an O-ring is installed.

그리고, 본 발명은 상기 제1부재(10)의 단부와 상기 제2부재(20)의 돌출부(22) 사이에 패킹하우징(30)이 설치된다. 여기서 상기 패킹하우징(30)은 탄성재질로 형성되는 것이 바람직하다.In the present invention, the packing housing 30 is installed between the end of the first member 10 and the protrusion 22 of the second member 20. Here, the packing housing 30 is preferably formed of an elastic material.

상기 패킹하우징(30)은, 상기 제2부재(20)의 외주면에 끼움 설치됨과 아울러 내주면 일측에는 상기 패킹부재(40)를 수용할 수 있도록 수용홈(32)이 형성되고 상기 제1,2부재(10)(20)의 나사결합시 상기 제1부재(10)의 단부와 제2부재(20)의 돌출부(22) 사이에서 상대면에 밀착된다.The packing housing 30 is fitted to the outer circumferential surface of the second member 20 and an accommodation groove 32 is formed on one side of the inner circumferential surface to accommodate the packing member 40 and the first and second members. When screwing the (10) (20) is in close contact with the mating surface between the end of the first member 10 and the protrusion 22 of the second member (20).

여기서, 상기 수용홈(32)의 폭(W1)은 상기 패킹부재(40)의 폭(W2) 보다 작은 것이 바람직하다.Here, it is preferable that the width W1 of the receiving groove 32 is smaller than the width W2 of the packing member 40.

즉, 상기 제1,2부재(10)(20)의 강한 나사 조임시 상기 패킹하우징(30)이 상기 제1,2부재(10)(20)의 사이에서 압착되더라도 상기 수용홈(32)은 상기 패킹부재(40)가 탄력성을 유지하도록 적정공간을 확보해주게 됨과 아울러 상기 패킹부재(40)를 보호하는 역할을 하게 된다.That is, even when the packing housing 30 is compressed between the first and second members 10 and 20 when the first and second members 10 and 20 are tightened with a strong screw, the receiving groove 32 is The packing member 40 secures an appropriate space to maintain elasticity and serves to protect the packing member 40.
