Description

역지밸브{CHECK VALVE}Check valve {CHECK VALVE}

본 고안은 유체(流體)가 이송되는 수직 또는 수평배관의 도중에 설치되는 밸브(VALVE)에 관한 것이다.The present invention relates to a valve (VALVE) that is installed in the middle of the vertical or horizontal piping through which the fluid (flow) is transferred.

더욱 상세하게는 상기 배관의 도중에 설치되어 유체의 역류(逆流)를 방지하는 역할을 하는 역지밸브(CHECK VALVE)와 흐르는 유체의 유량(流量)을 조절하는 역할의 게이트밸브(GATE VALVE)의 기능을 복합시킨, 유량의 조절이 가능한 역지밸브에 관한 것이다.More specifically, the function of the check valve installed in the middle of the pipe to prevent the back flow of the fluid (CHECK VALVE) and the gate valve (GATE VALVE) to adjust the flow rate of the flowing fluid The present invention relates to a check valve in which a flow rate can be adjusted.

종래의 역지밸브는 수직 또는 수평배관의 도중에 설치되어 유체가 흐르지 않고 정지되었을 때, 배관의 기울기나 중력등에 의해 유체가 역방향으로 흐르는 현상을 방지하는 것이 목적이었고, 흐르는 유체의 유량을 조절하기 위해 상기 역지밸브의 후단부에 별도의 게이트밸브가 설치되도록 하였다.The conventional check valve is installed in the middle of a vertical or horizontal pipe, and when the fluid stops without flowing, the purpose was to prevent the fluid from flowing backward due to the inclination or gravity of the pipe. A separate gate valve is to be installed at the rear end of the check valve.

그러나, 상기와 같은 통상의 밸브설치방식으로 밸브설치를 하였을 때 역지밸브와 게이트밸브가 각각 별개로 설치되므로 밸브설치비용을 증가시키게 되며, 상기 역지밸브가 노후되었을때 밸브디스크의 마모등으로 유체의 흐름이 완전히 차단되지 않는다는 문제점등이 있었다.However, when the valve is installed in the conventional valve installation method as described above, the check valve and the gate valve are separately installed, thereby increasing the valve installation cost. There was a problem that the flow was not completely blocked.

본 고안의 목적은 상기와 같은 종래 기술의 단점인 역지밸브와 게이트밸브의 설치시에 비용상승이라는 문제점을 해결하기위해, 역지밸브와 게이트밸브의 기능을 복합시킴으로써, 하나의 역지밸브로써 유체의 역류방지기능은 물론 유량조절기능까지도 가능케하여 설치비용을 절감시킬 수 있고, 부수적인 효과로써 역지밸브가 노후되어 유체의 흐름이 완전히 차단되지 않을경우에도 상기 개량형 역지밸브에서는 밸브대를 내림으로써 밸브디스크를 강하게 압박하여, 역지밸브의 밀폐기능을 더욱 향상시킬 수 있는 등의 보다 개선된 역지밸브를 제공하는데 그 목적이 있다.The purpose of the present invention is to solve the problem of the increase in the cost of the installation of the check valve and the gate valve of the prior art as described above, by combining the function of the check valve and the gate valve, the back flow of the fluid as one check valve The installation cost can be reduced by preventing flow as well as by adjusting the flow rate. As a side effect, even if the check valve is old and the flow of fluid is not completely blocked, the improved check valve lowers the valve disc. It is an object to provide a more improved check valve, such as being able to press hard, to further improve the sealing function of the check valve.

수직 또는 수평배관에 설치하여 유체의 역류를 방지하는 역할을 하는 통상의 역지밸브에서, 상기 목적을 달성하기 위한 본 고안에 따른 역지밸브는, 통상의 역지밸브의 기능을 하면서도 상기 역지밸브의 상부에 밸브대와 밸브핸들을 설치하여 밸브디스크의 개폐정도를 임의로 조절할 수 있도록 구성된 것을 특징으로 한다.In a conventional check valve installed in a vertical or horizontal pipe to prevent backflow of fluid, the check valve according to the present invention for achieving the above object, while functioning as a normal check valve, on the upper portion of the check valve It is characterized in that it is configured to arbitrarily adjust the opening and closing degree of the valve disc by installing the valve stem and the valve handle.

도 1과 도 2를 참조하여, 본 고안에 따른 역지밸브(1)를 더욱 상세히 설명하면, 상기 역지밸브(1)의 내부에 회동핀(6)을 기준으로 회동가능한 구조를 가지고 전면에는 밀폐패킹(4b)이 부착된 밸브디스크(4)가 설치되고, 상기 밸브디스크(4)의 후면에 눌림경사부(4a)를 일체로 형성하였으며, 상기 역지밸브의 상부에는 높낮이를 조절할 수 있는 밸브대(2)와 밸브핸들(14)을 설치하여 밸브대(2)를 내리는 정도에 따라 상기 눌림경사부(4a)를 압박해줌으로써 밸브디스크(4)의 개폐정도를 조절할 수 있다.Referring to Figures 1 and 2, the check valve 1 according to the present invention in more detail, has a structure that can be rotated based on the rotation pin (6) in the inside of the check valve (1) and sealed packing on the front (4b) is attached to the valve disk (4) is installed, the pressing inclination portion (4a) is integrally formed on the rear of the valve disk (4), the upper of the check valve valve for adjusting the height ( 2) and the valve handle 14 to adjust the opening and closing degree of the valve disc 4 by pressing the inclined inclined portion (4a) according to the degree of lowering the valve stem (2).

또한, 상기 밸브대(2)를 완전히 올리면 밸브디스크(4)가 유체의 흐름에 의해 자유개폐될 수 있어 통상의 역지밸브의 역할을 할 수 있다.In addition, when the valve stem (2) is raised completely, the valve disc (4) can be freely opened and closed by the flow of the fluid can serve as a normal check valve.

미설명부호 10은 유로의 유입측, 12는 유로의 유출측이다.Reference numeral 10 denotes an inflow side of the flow path and 12 an outflow side of the flow path.

이상에서 설명한 바와같이, 본고안에 따른 역지밸브는 통상의 밸브설치방식인 역지밸브와 게이트밸브를 각각 설치하는 복수적인 개념의 설치방식을 개선하여 상기의 개량된 역지밸브를 사용함으로써, 유체의 역류 방지기능과 유량의 조절기능을 병행할 수 있게하여, 밸브설치비용을 획기적으로 절감시킬 수 있으며, 또한 임의로 유체의 흐름을 차단시켜야 할 경우에 통상의 게이트밸브보다 밀폐기능이 더욱 향상되는 효과를 제공하는것이다.As described above, the check valve according to the present invention improves the installation method of the plural concepts of installing the check valve and the gate valve, which are the normal valve installation methods, respectively, and thereby prevents the backflow of the fluid by using the improved check valve. By combining the function with the function of adjusting the flow rate, it is possible to drastically reduce the valve installation cost, and also to provide the effect of improving the sealing function more than the normal gate valve when the flow of the fluid should be arbitrarily blocked. will be.
