The installation structure of the valve to be installed and replaced without the need for a pipe or the like.
일반적으로 밸브는 관로(管路)의 도중이나 용기에 설치하여, 유체의 유량 또 는 압력 등의 제어를 하는 장치로서, 스톱밸브, 게이트 밸브, 체크 밸브, 콕, 플러그 밸브, 볼 밸브, 다이어프램 밸브, 핀치 밸브 등 여러가지 구조와 형태로 널리 사용되고 있다.In general, the valve is installed in the pipeline or in a container to control the flow rate or pressure of the fluid, such as a stop valve, a gate valve, a check valve, a cock, a plug valve, a ball valve, and a diaphragm valve. It is widely used in various structures and forms, such as a pinch valve.
도 1은 종래에 따른 밸브의 설치구조를 설명하기 위한 도면이다.1 is a view for explaining the installation structure of the valve according to the prior art.
도시된 바와 같이 도 1의 (가)와 같이 동일선상에 서로 대향되도록 단부에 플랜지(1a)(2a)가 각각 형성된 한쌍의 배관(1)(2) 사이에 상기 플랜지(1a)(2a)에 대응되는 플랜지부(3a)가 형성된 밸브(3)가 고정되어 있다.As shown in Fig. 1A, the flanges 1a and 2a are formed between a pair of pipes 1 and 2, each of which has flanges 1a and 2a formed at ends thereof so as to face each other on the same line. The valve 3 in which the corresponding flange part 3a was formed is fixed.
즉, 상기 배관(1)(2)의 플랜지(1a)(2a)에 형성된 관통공과 상기 밸브(3)에 형성된 플랜지부(3a)에 형성된 관통공을 상호 일치시킨 상태에서 체결부재(4)로 결합하게 된다.That is, the through hole formed in the flange (1a) 2a of the pipe (1) (2) and the through hole formed in the flange portion (3a) formed in the valve (3) to the fastening member (4) Will be combined.
상기와 같이 설치된 밸브(3)를 장시간 사용으로 인한 노후화 또는 고장이 발생하여 교체할 필요가 생길 경우에는 체결부재(4)를 풀고, 배관(1)(2) 사이에 설치된 밸브(3)를 분리하게 된다.If the valve 3 installed as described above needs to be replaced due to aging or failure due to prolonged use, loosen the fastening member 4 and separate the valve 3 installed between the pipes 1 and 2. Done.
그러나, 상기와 같이 교체할 밸브(3)를 제거한 상태에서 신품 밸브(5)를 설치하기 위해서는 도 1의 (나)에 에 도시한 바와 같이 신품 밸브(5)를 설치하기 위한 공간(L)을 확보하기 위해 타측 배관(2)의 플랜지(2a)를 포함하여 배관(2)을 절단하게 된다.However, in order to install the new valve 5 in a state where the valve 3 to be replaced is removed as described above, as shown in FIG. 1B, a space L for installing the new valve 5 is provided. In order to ensure the pipe 2 is cut including the flange 2a of the other pipe 2.
즉, 밸브(3)의 플랜지부(3a)와 배관(1)(2)의 플랜지(1a)(2a) 사이에 접합패킹(3b)을 끼워야 됨으로 신품 밸브(5)를 교체하기가 어려운 문제점이 있다.That is, it is difficult to replace the new valve 5 because the joint packing 3b must be fitted between the flange portion 3a of the valve 3 and the flanges 1a and 2a of the pipe 1 and 2. have.
따라서, 상기와 같이 타측 배관(2)을 절단하여 확보된 공간에 도 1의 (다)에 도시한 바와 같이 신품 밸브(5), 신축관(6), 단관(7) 및 보강링(8) 등을 순차적으로 결합하게 된다.Therefore, the new valve 5, the expansion pipe 6, the short pipe 7 and the reinforcing ring 8 as shown in Fig. 1 (c) in the space secured by cutting the other side pipe (2) as described above. And the like sequentially combined.
그러나, 상기와 같이 신품 밸브(5)를 교체하기 위해서는 타측 배관(2)을 절단한 후 신품밸브(5), 신축관(6)을 연결할 뿐만 아니라 절단된 배관(2)에 보강링(8)을 용접하고, 단관(7)을 결합하도록 함으로서, 교체 작업이 어렵고, 불필요한 자재 등이 많이 소요되는 문제점이 있다.However, in order to replace the new valve 5 as described above, after cutting the other side pipe (2), as well as connecting the new valve (5), expansion pipe (6) as well as reinforcing ring (8) to the cut pipe (2) By welding and by coupling the short pipe (7), there is a problem that the replacement work is difficult, a lot of unnecessary materials and the like.
본 발명은 이러한 종래의 문제점을 해결하기 위하여 이루어진 것으로, 그 목적은 동일선상에 서로 대향되도록 단부에 플랜지가 각각 형성된 한쌍의 배관 사이에 상기 플랜지에 대응되는 플랜지부가 형성된 밸브를 배관의 절단 등의 공정 및 신축관 등의 필요없이 설치 및 교체하도록 하는 밸브의 설치구조를 제공함에 있다.The present invention has been made to solve such a conventional problem, the object of the process is to cut the valve between the flanges corresponding to the flange between a pair of pipes each formed with a flange at the end so as to face each other on the same line And to provide an installation structure of the valve to be installed and replaced without the need for expansion pipes and the like.

도 3의 (가)에 도시한 바와 같이 종래의 밸브(3)를 배관(10)(20)의 플랜지(11)(21) 사이(B)에 결합한 상태에서 밸브의 노후화 또는 밸브의 고장 발생으로 밸브를 교체할 필요가 발생하게 되면, 도 3의 (나)에 도시한 바와 같이 종래의 밸브(3)를 철거하게 된다.As shown in Fig. 3A, the valve 3 is connected to the flanges 11 and 21 of the pipes 10 and 20 between the flanges 11 and 21, thereby causing aging of the valve or failure of the valve. If a need arises to replace the valve, the conventional valve 3 is removed as shown in FIG.
이때 종래와 같이 타측 배관을 절단할 필요가 없으며, 종래의 밸브(3)만 제거하게 된다.At this time, it is not necessary to cut the other side pipe as in the prior art, and only the conventional valve 3 is removed.
상기의 상태에서 도 3의 (다)에 도시한 바와 같이 배관(10)(20)의 플랜지(11)(21) 사이(B)에 본 발명의 밸브(30)를 결합시키게 되는데. 이때 밸브(30)의 고정플랜지부(31)와 일측 배관(10)의 플랜지(11) 사이에 접합패킹(70)을 삽입한 상태에서 체결부재(60)로 결합하게 되고, 또한, 이동플랜지부(32)를 도면상 우측으로 이동시켜 타측 배관(20)의 플랜지(21)와 체결부재(60)로 고정하게 된다.In the above state, as shown in (c) of FIG. 3, the valve 30 of the present invention is coupled between the flanges 11 and 21 of the pipes 10 and 20. In this case, the joint flange 70 is inserted between the fixed flange portion 31 of the valve 30 and the flange 11 of the one side pipe 10, and then coupled to the fastening member 60, and the movable flange portion The 32 is moved to the right in the drawing to be fixed to the flange 21 and the fastening member 60 of the other side pipe 20.
즉, 밸브(30)의 길이가 배관(10)(20)의 플랜지(11)(21)면 보다 작게 이루어져 용이하게 배관(10)(20)의 플랜지(11)(21) 사이(B)에 결합되는 것이다.That is, the length of the valve 30 is made smaller than the flange 11, 21 surface of the pipe 10, 20 between the flange 11, 21 of the pipe 10, 20 easily (B). To be combined.
또한, 상기 이동플랜지부(32)의 일측 내측면에 패킹부재(40)와 상기 패킹부재(40)의 내주면에 가이드링(50)을 결합하도록 하여 유체의 누설을 방지하게 되는 것이다.In addition, the guide member 50 is coupled to the packing member 40 and the inner circumferential surface of the packing member 40 on one inner side surface of the movable flange part 32 to prevent leakage of the fluid.
한편, 본 발명은 밸브(30)는 기존밸브를 제거하고 교체하는 것을 일예로 설명하였으나, 이에 한정되는 것이 아니고, 밸브를 처음 설치할 때도 본 발명의 밸브(30)를 적용하는 것은 당연한 것이다.On the other hand, the present invention has been described as an example that the valve 30 to remove and replace the existing valve, but is not limited to this, it is natural to apply the valve 30 of the present invention even when the valve is first installed.
