Description
본 고안은 유체관로의 약45도 방향에서 밸브본체를 공기압으로 작동하여 유체의 흐름을 개폐할수 있도록한 Y형 밸브에 체크밸브기능을 함께 할수 있도록 구성하여 유체를 일방향으로만 안전하게 흐르도록 한 것이다.The present invention is designed to allow the fluid to flow safely in only one direction by configuring a check valve function on a Y-type valve that opens and closes the flow of the fluid by operating the valve body at about 45 degrees of the fluid line.
일반적으로 Y형 밸브에서는 밸브본체의 작동축에 승강판을 일체로 부착하여 압축스프링으로 승강판을 상승되게 탄성지지하고 압축공기를 불어넣어 승강판을 하강시키는 구성으로 밸브본체를 밸브시트에 밀착시키거나 이격되게 하여 유체관로를 개폐하였었다.In general, in the Y-type valve, a lifting plate is integrally attached to the operation shaft of the valve body to elastically support the lifting plate by a compression spring and blow the compressed air to lower the lifting plate. Fluid lines were opened or closed.
그러나 상기의 Y형 밸브에서는 압축공기에 의한 공기압으로 승강판이 하강하여 유체관로의 개방으로 유체공급을 하는 동안 유체 흐름이 역방향으로 진행되는 것을 차단하기 위해서는 유체관로에 별도로 구성된 체크밸브를 설치해야 되므로 설치비용도 많이들고 설치공간도 많이 차지하는 등 문제점이 있었다.However, in the above Y-type valve, in order to block the flow of the fluid flow in the reverse direction while the lifting plate descends due to the air pressure by compressed air and the fluid supply is opened by the opening of the fluid passage, a check valve configured separately must be installed in the fluid passage. There were problems such as high cost and a lot of installation space.
본 고안은 이러한 문제점을 해결하기 위하여 Y형 밸브의 밸브본체에 접속관을 결합하여 작동축을 슬라이드되게 접속하고 밸브본체 하부에 스프링을 탄성지지시킨 구성으로 공기압으로 밸브본체를 하강시켜 유체공급이 이루어지는 동안에 유체흐름이 역방향으로 진행되면 작동축 선단에 끼워진 밸브본체가 유체압력으로 상승하여 밸브시트에 말착되게한 유체역류 방지수단으로 체크밸브기능을 갖도록한 것이다.In order to solve this problem, the present invention is configured to connect the connecting pipe to the valve body of the Y-type valve so as to slide the operating shaft and elastically support the spring at the lower part of the valve body. When the fluid flow proceeds in the reverse direction, the valve body fitted to the end of the operating shaft rises to the fluid pressure and is provided with a check valve function as a fluid backflow prevention means that is attached to the valve seat.

유체관로(10)에 약45도 방향으로 밸브본체(12)가 진퇴작용하여 밸브시트(11)를 개폐시키되 밸브본체(12)의 작동축(16)에 승강작동판(21)이 부착되어 작동실 (20)내에서 탄성지지된 강한 압축스프링(22)으로 승강작동판(21)을 상승작용하고 작동실(20)내에 압축공기를 불어 넣어 승강작동판(21)을 하강작용하는 승강수단으로 밸브본체(12)의 개폐작용이 이루어지도록한 Y형 밸브에 있어서, 상기 밸브본체 (12)에 접속관(13)을 결합하고 그 접속관(13)에 작동축(16)선단을 슬라이드되게 접속하며 밸브본체(12)하부와 밸브승강실(14)상면사이에 유체압력보다 훨씬 낮은 압축강도를 가진 스프링(15)을 개입히켜 유체진행에 영향을 주지 않으면서 밸브본체 (12)를 탄성지지되게하여 밸브본체에 의한 역류방지수단을 구비한 것이다.The valve body 12 moves back and forth to the fluid line 10 in the direction of about 45 degrees to open and close the valve seat 11, and the lifting operation plate 21 is attached to the operating shaft 16 of the valve body 12. As a lifting means for lifting and lowering the elevating operating plate 21 by the strong compression spring 22 elastically supported in the chamber 20 and blowing compressed air into the operating chamber 20. In the Y-type valve in which the valve body 12 is opened and closed, the connecting tube 13 is coupled to the valve body 12 and the front end of the operating shaft 16 is slidably connected to the connecting tube 13. And a spring 15 having a compressive strength much lower than the fluid pressure between the lower part of the valve body 12 and the upper surface of the valve lift chamber 14 to elastically support the valve body 12 without affecting the fluid flow. It is to provide a backflow prevention means by the valve body.
그리고 유체관로(10)의 유체진행방향은 도면에 표시된 바와 같이 'A'부분에서 'B'부분으로 공급되도록 한다.And the fluid flow direction of the fluid line 10 is to be supplied from the 'A' portion to the 'B' portion as shown in the figure.
도면중 미설명부호 23은 압축공기압 공급부이다.In the figure, reference numeral 23 denotes a compressed air pressure supply unit.
이와같이된 본 고안은 밸브의 밸브시트(11)를 개방하여 유체관로(10)의 'A'부분에서 'B'부분으로 유체를 공급하기 위해 작동실(20)내에 압축공기를 불어 넣게되면 압축스프링(22)으로 탄성지지된 승강작동판(21)이 하강하면서 이와 연결된 작동축(16)이 하강함과 아울러 작동축(16)선단에 끼워진 밸브본체(12)가 유체압력으로 밸브시트(11)에서 이격되어 유체공급이 이루어지게 되며, 밸브본체(12)를 밸브시트(11)에 밀착시켜 유체관로(10)의 유체를 차단할때에는 작동실(20)내에 불어넣은 압축공기를 빼내게 되면 승강작동판(21)을 탄성지지하고 있는 압축스프링(22)의 탄발력으로 승강작동판(21)이 상승함과 동시에 이와 연결된 작동축(16)이 상승하여 작동축(16)선단에 접속된 밸브본체(12)를 밸브시트(11)에 밀착되는 수단으로 유체관로(10)의 유체공급을 차단하게 된다.The present invention has a compression spring when the compressed air is blown into the operating chamber 20 to supply the fluid from the 'A' portion to the 'B' portion of the fluid line 10 by opening the valve seat 11 of the valve. As the lifting and lowering operation plate 21 elastically supported by (22) descends, the operating shaft 16 connected thereto descends, and the valve body 12 fitted to the end of the operating shaft 16 is fluidized by the valve seat 11. When the fluid supply is spaced apart from each other, the valve body 12 is brought into close contact with the valve seat 11 to shut off the fluid in the fluid line 10. When the compressed air blown into the operation chamber 20 is removed, the lifting operation is performed. The elevating operation plate 21 is raised by the elastic force of the compression spring 22 elastically supporting the plate 21, and the operating shaft 16 connected thereto is raised to connect the valve body connected to the end of the operating shaft 16. (12) closes the fluid supply to the fluid line (10) by means of close contact with the valve seat (11) .
이러한 유체개폐수단을 가진 Y형 밸브에서 밸브본체(12)가 밸브시트(11)에서 이격되어 밸브시트(11)의 개방으로 유체관로(10)의 'A'부분에서 'B'부분으로 유체공급이 이루어지는 동안에 'A'부분의 유체압력이 크게 낮아져서 유체관로(10)의 'B'부분에서 'A'부분으로 유체흐름이 역방향으로 진행되는 역류발생시에는 작동축(16)선단에 접속된 밸브본체(12)가 역방향유체압력으로 상승하여 밸브시트 (11)에 밀착되므로 유체관로(10)를 차단하여 역류를 방지하게 된다.In the Y-type valve having the fluid opening and closing means, the valve body 12 is spaced apart from the valve seat 11 to supply fluid from the 'A' portion of the fluid line 10 to the 'B' portion by opening the valve seat 11. During this process, the fluid pressure in the 'A' part is significantly lowered, so that the valve body connected to the end of the operating shaft 16 when the reverse flow occurs in which the fluid flow is reversed from the 'B' part to the 'A' part of the fluid line 10 is reversed. Since the 12 rises to the reverse fluid pressure and closely adheres to the valve seat 11, the fluid line 10 is blocked to prevent backflow.
즉, 작동실(20)에 압축공기를 불어넣어 작동축(16)하강으로 밸브본체(12)를 밸브시트(11)에서 이격시켜 유체공급이 일방향으로 진행되다가 유체가 역류되면 작동축(16)의 승강작용없이 작동축(16)에 접속된 밸브본체(12)가 역류되는 유체압력으로 상승되어 밸브시트(11)를 차단하는 체크밸브 기능을 하게 되는 것이다.That is, the compressed air is blown into the operation chamber 20 to separate the valve body 12 from the valve seat 11 by lowering the operating shaft 16 so that the fluid supply proceeds in one direction and the fluid flows backward. The valve body 12 connected to the operating shaft 16 is elevated to the backflow fluid pressure without a lifting action to act as a check valve to block the valve seat 11.
이와같이 본 고안은 밸브본체를 공기압으로 작동하여 유체흐름을 개폐할수 있도록한 Y형 밸브에서 유체흐름이 역류될때에는 역류되는 유체압력에 의해 밸브본체가 밸브시트에 밀착되어 유체를 차단하는 체크밸브기능으로 유체를 일방향으로만 안전하게 흐르도록하며 그 체크밸브수단도 간단한 구성으로 이루어져서 매우 경제적인 이점이 있는 것이다.As such, the present invention is a check valve function in which the valve body is in close contact with the valve seat by the fluid pressure flowing back when the fluid flow is reversed in the Y-type valve which operates the valve body at pneumatic pressure to open and close the fluid flow. The fluid flows safely in only one direction, and the check valve means has a simple configuration, which is very economical.
