본 발명은 밸브의 설치구조에 관한 것으로, 더욱 상세하게는 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 설치구조에 관한 것이다.The present invention relates to an installation structure of the valve, and more particularly, a process in which a flange portion corresponding to the flange is formed between a pair of pipes each having a flange formed at an end thereof so as to face each other on the same line, such as cutting a pipe and stretching the pipe. 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.

이러한 목적을 달성하기 위한 본 발명은 동일선상에 서로 대향되도록 단부에 플랜지가 각각 형성된 한쌍의 배관 사이에 상기 플랜지에 대응되는 플랜지부가 형성된 밸브를 고정하도록 하는 밸브의 설치구조에 있어서, 상기 밸브의 길이는 상기 배관의 플랜지면 사이 보다 작게 이루어지고, 상기 밸브의 일측 외주면에는 고정플랜지부를 일체로 형성하여 일측 배관의 플랜지에 체결부재로 고정시키며, 상기 밸브의 타측 외주면에는 이동플랜지부를 좌,우로 이동가능하게 설치하되 상기 이동플랜지부의 일측 내측면에 패킹부재를 결합하여 상기 이동플랜지부를 타측 배관의 플랜지에 체결부재로 직접 고정하는 것을 특징으로 한다.In order to achieve the above object, the present invention provides a valve mounting structure for fixing a valve having a flange portion corresponding to the flange between a pair of pipes each having a flange formed at an end thereof so as to face each other on the same line. It is made smaller than between the flange surface of the pipe, one side of the outer peripheral surface of the valve is formed integrally fixed to the fastening member to the flange of one side of the pipe, and the other side of the valve of the movable flange left and right The movable flange is coupled to one side inner surface of the movable flange portion, and the movable flange portion is directly fixed to the flange of the other pipe by a fastening member.

또한, 상기 밸브(30)의 일측 외주면에는 고정플랜지부(31)를 일체로 형성하여 일측 배관(10)의 플랜지(11)에 체결부재(60)로 고정시키며, 상기 밸브(30)의 타측 외주면에는 이동플랜지부(32)가 좌,우로 이동가능하게 설치된다.In addition, the fixed flange portion 31 is integrally formed on one side outer circumferential surface of the valve 30 to be fixed to the flange 11 of the one side pipe 10 by the fastening member 60, and the other outer circumferential surface of the valve 30. The movable flange 32 is installed to be movable left and right.

즉, 상기 밸브(30)의 고정플랜지부(31)를 일측 배관(10)의 플랜지(11)에 체결부재(60)로 고정한 상태에서 상기 이동플랜지부(32)를 좌,우로 이동시켜 타측 배관(20)의 플랜지(21)에 체결부재(60)로 직접 결합하도록 함으로서, 설치성을 향상시킬 수 있게 된다.That is, while the fixing flange 31 of the valve 30 is fixed to the flange 11 of one pipe 10 by the fastening member 60, the movable flange 32 is moved to the left and right to move the other pipe. Direct coupling to the flange 21 of the 20 by the fastening member 60, it is possible to improve the installation.

또한, 상기 이동플랜지부(32)의 일측 내측면에 패킹부재(40)를 결합하여 타측 배관(20)의 플랜지(21)에 고정되도록 하여 유체의 누설을 방지하게 된다.In addition, the packing member 40 is coupled to one inner side surface of the movable flange portion 32 to be fixed to the flange 21 of the other side pipe 20 to prevent leakage of the fluid.

그리고, 상기 패킹부재(40)의 내주면에는 가이드링(50)이 결합되도록 하여 상기 이동플랜지부(32)와 타측 배관(20)의 플랜지(21)가 체결부재(60)로 결합되는 과정에서 패킹부재(40)가 밸브(30)와 타측 배관(20)의 플랜지(21) 사이에 끼여 패킹부재(40) 사이로 유체의 누수를 방지하게 된다.In addition, the guide ring 50 is coupled to the inner circumferential surface of the packing member 40 so that the flange 21 of the movable flange 32 and the other side pipe 20 is coupled to the fastening member 60. The member 40 is sandwiched between the valve 30 and the flange 21 of the other side pipe 20 to prevent leakage of fluid between the packing member 40.

한편, 미설명 부호 70은 밸브의 고정플랜지부(31)와 일측 배관(10)의 플랜지(11) 사이의 접합패킹을 나타낸다.On the other hand, reference numeral 70 denotes a joint packing between the fixed flange portion 31 of the valve and the flange 11 of the one side pipe (10).
