유동 플랜지를 가지는 버터플라이 밸브{BUTTERFLY VALVE WITH FLOW FLANGE} Butterfly valve with flow flange {BUTTERFLY VALVE WITH FLOW FLANGE}

본 발명은 유동 플랜지를 가지는 버터플라이 밸브에 관련되는 것으로서, 더욱 상세하게는 파이프와 밸브를 연결하는 플랜지가 밸브 몸체 외경을 타고 이동하도록 구성하여 밸브 교체과정에서 파이프와 밸브 사이에 발생하는 틈새를 차단할 수 있도록 한 유동 플랜지를 가지는 버터플라이 밸브에 관한 것이다.The present invention relates to a butterfly valve having a flow flange, and more particularly, the flange connecting the pipe and the valve is configured to move through the outer diameter of the valve body to block the gap between the pipe and the valve during the valve replacement process. A butterfly valve having a flow flange is provided.

잘 알려진 바와 같이, 버터플라이 밸브는 일명 접형변이라고도 일컬어 지는 것으로서, 원판의 형상을 가진 디스크의 회동동작에 따라 밸브를 개폐시켜 유량을 조절할 수 있도록 고안된 밸브를 말한다.As is well known, the butterfly valve is also called a foldable side, it refers to a valve designed to control the flow rate by opening and closing the valve in accordance with the rotation of the disk of the disk shape.

상기한 버터플라이 밸브는 관로 사이에 설치되며 내부에는 유로가 형성된 밸브 몸체와, 상기 밸브 몸체의 유로를 개폐시키는 디스크 및 상기 디스크에 결합되며 상기 밸브 몸체 외부에 설치되어 있는 구동원의 동력으로 상기 디스크를 회전 동작시키는 구동축을 포함하여 구성한다.The butterfly valve is installed between the pipelines and the valve body is formed therein, a disk for opening and closing the flow path of the valve body and the disk coupled to the disk and driven by the power of the drive source installed outside the valve body It comprises a drive shaft for rotating operation.

상기한 버터플라이 밸브와 관로와의 연결은 상기 관로의 일단에 플랜지를 형 성하고, 또한 상기 버터플라이 밸브의 일단에도 플랜지를 형성한 다음, 상기 각각의 플랜지를 서로 맞댄 상태에서 볼트 및 너트를 체결시켜 버터플라이 밸브와 관로를 서로 연결 구성하게 된다.The connection between the butterfly valve and the conduit forms a flange at one end of the conduit, and also forms a flange at one end of the butterfly valve, and then fastens bolts and nuts in a state where the respective flanges face each other. The butterfly valve and the pipeline are connected to each other.

한편, 상기와 같이 연결 구성된 버터플라이 밸브는 일정 기간마다 밸브의 노후화 및 고장 등으로 인해 새것으로 교체하는 작업을 진행하게 된다. On the other hand, the butterfly valve connected as described above is going to replace the work with a new one due to the aging and failure of the valve every predetermined period.

그러나 종래에는 밸브를 교체하는 과정에서 플랜지 고무 패킹의 간섭으로 밸브를 철거한 공간 내에 신품의 밸브를 끼워 넣을 수 없어 항상 배관 절단, 접합플랜지 용접, 밸브 체결, 신축관 체결 등의 순으로 공사가 이루어지게 됨으로서 작업공정이 번거롭다는 단점이 있다.Conventionally, however, new valves cannot be inserted into the space from which the valve was removed due to interference of the flange rubber packing during the valve replacement process. The disadvantage is that the work process is cumbersome.

특히 교체되는 밸브의 규격이 조금 다를 경우에는 밸브와 관로 사이에 틈새가 발생하게 됨으로서 기밀성에도 많은 문제점을 유발하게 된다.In particular, when the size of the valve to be replaced is slightly different, a gap occurs between the valve and the pipe line, which causes many problems in airtightness.

따라서, 상기한 바와 같은 문제점을 해결하기 위한 본 발명의 목적은 파이프와 밸브를 연결하는 플랜지가 밸브몸체 외경을 타고 이동하도록 구성하여 밸브 교체과정에서 파이프와 밸브 사이에 발생하는 틈새를 차단할 수 있도록 한 유동 플랜지를 가지는 버터플라이 밸브를 제공함에 있다.Accordingly, an object of the present invention for solving the above problems is to configure the flange connecting the pipe and the valve to move along the outer diameter of the valve body to block the gap generated between the pipe and the valve during the valve replacement process. A butterfly valve having a flow flange is provided.

본 발명이 이루고자 하는 또 다른 기술적 과제는 파이프와 밸브를 연결하는 플랜지가 밸브몸체 외경을 타고 이동하도록 구성하여 밸브의 수리 및 유지관리를 위한 교체시에도 파이프를 절단하거나 용접 등의 공정작업이 필요치 않아 시공이 아주 간편하도록 하는 유동 플랜지를 가지는 버터플라이 밸브를 제공함에 있다.Another technical problem to be achieved by the present invention is that the flange connecting the pipe and the valve is configured to move on the outer diameter of the valve body so that even when the replacement for repair and maintenance of the valve does not require a process such as cutting the pipe or welding. It is to provide a butterfly valve having a flow flange to make the construction very easy.

상술한 목적들을 달성하기 위한 본 발명은 관로 사이에 설치되며 내부에는 유로가 형성된 밸브 몸체와, 상기 밸브 몸체의 유로를 개폐시키는 디스크 및 상기 디스크를 구동시키는 구동축을 포함하여 구성한 버터플라이 밸브에 있어서, 상기 밸브몸체의 일측에는 연장관이 일체 연장 형성되며, 상기 연장관의 외경에는 상기 관로에 형성되어 있는 플랜지와 볼트 및 너트 체결되는 제 1, 2유동플랜지가 끼워지며, 상기 제 1, 2유동플랜지는 상기 연장관의 외경을 타고 이동하며 상기 밸브몸체와 상기 관로 사이에 형성된 틈새를 차단하도록 하며, 상기 제 1유동플랜지와 상기 관로의 플랜지 사이에는 플랜지패킹이 끼워지고, 상기 제 1, 2유동플랜지 사이 에는 고무패킹이 더 끼워지도록 구성함을 특징으로 한다.According to an aspect of the present invention, there is provided a butterfly valve including a valve body having a flow path formed therebetween, a disk for opening and closing a flow path of the valve body, and a drive shaft for driving the disk. An extension pipe is integrally formed on one side of the valve body, and the first and second flow flanges, which are fastened to the flange and the bolt and the nut formed in the pipe, are fitted in the outer diameter of the extension pipe, and the first and second flow flanges are Moving through the outer diameter of the extension pipe to block the gap formed between the valve body and the pipeline, the flange packing is fitted between the flange of the first flow flange and the pipe, the rubber between the first and second flow flange Characterized in that the packing is further fitted.

본 발명에 따른 유동 플랜지를 가지는 버터플라이 밸브는 플랜지의 이동 구조를 통해 교체중에 있는 밸브의 규격이 다르더라도 파이프와 밸브 사이에 발생하는 틈새를 차단할 수 있어 기밀성을 유지할 수 있는 작용효과를 구현한다.The butterfly valve having a flow flange according to the present invention can block the gap generated between the pipe and the valve even though the size of the valve being replaced through the moving structure of the flange implements the effect of maintaining the airtightness.

또한 밸브를 분해하지 않고 플랜지의 이동만으로도 긴급한 보수작업 및 교체시간이 단축되어 예산 절감의 작용효과를 구현한다.In addition, the emergency maintenance work and replacement time can be shortened by moving the flange without disassembling the valve, thereby realizing the effect of saving the budget.
