* 도면의 주요 부분에 대한 부호의 설명* Explanation of symbols for the main parts of the drawings

1 : 밸브원판 6 : 가이드축1: valve disc 6: guide shaft

8 : 가이드실린더 11 : 가압스프링8: guide cylinder 11: pressure spring

본 고안은 게이트 밸브의 고안으로서 밸브원판에 가압스프링을 탄설하여 밸브원판에 탄접되고 동시에밸브원판과 배면의 가이드축이 밸브로드 스크류 내단의 가이드 실린더에 안내됨으로써 밸브원판이 밸브의 통상적인 개폐 기능과 동시에 역류 방지변체로서의 겸할 수 있게금 안출된 것이다.This invention is the design of the gate valve, the pressure spring is installed in the valve disc to make contact with the valve disc, and at the same time, the valve disc and the guide shaft on the back are guided to the guide cylinder inside the valve rod screw. At the same time, it was designed to serve as a reverse flow prevention variant.

종래의 게이트 밸브는 유체의 공급량을 조절하거나 관내의 유체 흐름을 개폐하는 단순기능을 갖는 것이고 유체의 역류를 방지하자면 별도의 체크밸브를 직렬로 장착해야만하는 것이었다.Conventional gate valves have a simple function of regulating the supply amount of the fluid or opening and closing the fluid flow in the pipe, and in order to prevent backflow of the fluid, separate check valves have to be mounted in series.

본 고안은 이와 같은 게이트 밸브와 체크 밸브의 독자적 기능을 종합하여 유체의 공급밸브로서 유체의 역류방지 기능을 겸하게끔 안출된 것으로서 첨부도면에 따라 상술하면 다음과 같다.The present invention is designed to combine the unique functions of the gate valve and the check valve as a function of preventing the backflow of the fluid as a supply valve of the fluid as described above according to the accompanying drawings.

밸브 본체의 중심축(S1)에 대하여 유입구를 향한 경사축(S2) 상의 밸브로드를 갖고 밸브시스와 접속된 밸브로드 내단부의 밸브원단이 밸브로드 스크류의 진퇴에 따라 동작하며 로드 홀더상의 지시침이 밸브로드상의 측정표지에 접속된 게이트 밸브에 있어서, 밸브로드스크류 내단 가압축(7)상의 가이드 실린더(8)에 밸브원판(1) 배면의 가이드축(6)이 삽입되고 밸브원판(1)과 로드홀더(10)사이에 가압스프링(11)이 탄설된 구조이며, 부호 2는 밸브로드, 3은 밸브본체, 4는 유입구, 5는 유출구, 9는, 로드스크류, 10은 로드홀더, 12는 밸브시트, 23은 측정표지, 14는 지시침, 15는 로드스크류홀더, 16,16'는 플랜지, 17,17'는 패킹 삽입홈이다.The valve far end of the valve rod inner end connected to the valve sheath with the valve rod on the inclined shaft S 2 facing the inlet port with respect to the central axis S 1 of the valve body operates as the valve rod screw moves forward and closes on the rod holder. In the gate valve in which the indicator needle is connected to the measurement mark on the valve rod, the guide shaft 6 on the back of the valve disc 1 is inserted into the guide cylinder 8 on the pressure rod 7 inside the valve rod screw, and the valve disc ( 1) and the load spring 10 is a structure in which the pressure spring 11 is installed, the sign 2 is the valve rod, 3 is the valve body, 4 is the inlet, 5 is the outlet, 9 is the rod screw, 10 is the rod holder 12 is valve seat, 23 is measuring mark, 14 is indicator needle, 15 is rod screw holder, 16 and 16 'is flange, 17 and 17' is packing insertion groove.

그러므로 본 고안은 로드홀더(10)에 의지된 로드(2)의 핸들을 조작하여 로드스크류 홀더(15)에 결합된 로드스크류(9)를 진퇴시키면 가압축(7)이 로드스크류(9)를 따라 진퇴함으로 가압축(7)을 전진시켜 밸브원판(1)을 밸브시트(12)에 가압하면 밸브는 폐전상태가 되는데, 이때에 밸브원판(1)과 밸브시트(12)는 밀접 상태가 되어 유입구(4)로 부터 유출구(5)로 흐르는 유체의 흐름을 차단하게 된다.Therefore, the present invention operates the handle of the rod 2 relied on the rod holder 10 to advance and retract the rod screw 9 coupled to the rod screw holder 15 so that the pressure shaft 7 moves the rod screw 9. Accordingly, when the pressure disc 7 is pushed forward and the valve disc 1 is pressed against the valve seat 12, the valve is in a closed state. At this time, the valve disc 1 and the valve seat 12 are in a close state. Block the flow of fluid from the inlet (4) to the outlet (5).

위와는 반대로 로드 스크류(9)를 후퇴시켜 가압축(7)을 밸브원판(1)으로부터 격리시키면 개전상태가 되는데 이때에는 가압스프링(11)만이 밸브원판(1)을 가압하는 상태가 되므로 유입구(4)로부터 유출구(5)방향으로 흐르는 정방향의 밸브원판(1)저면에 유체 압력을 가하여 밸브원판(1) 배면의 가이드축(6)은 가압축의 가이드실린더(8)에 안내됨과 공시에 스프링(11)이 가압되면더 로드스크류(9)로 부터 유입구(4)로 흐르는 역류가 발생되면 스프링(11)이 가압력으로 밸브원판(1)이 밸브시트(12)에 밀착될뿐 아니라 역류에 의한 부압도 밸브원판(1)을 감압하게 되어 밸브는 완전히 닫히게 된다.On the contrary, when the rod screw 9 is retracted to isolate the pressure shaft 7 from the valve disc 1, it is in an open state. At this time, only the pressure spring 11 presses the valve disc 1 so that the inlet ( A fluid pressure is applied to the bottom surface of the valve disc 1 in the forward direction from 4) to the outlet port 5 so that the guide shaft 6 on the back of the valve disc 1 is guided to the guide cylinder 8 of the pressure shaft, When 11) is pressurized, when a reverse flow flowing from the rod screw 9 to the inlet 4 is generated, the spring 11 is pressurized so that the valve disc 1 is in close contact with the valve seat 12 and the negative pressure due to the reverse flow. In addition, the valve disc 1 is decompressed so that the valve is completely closed.

위와 같이 본 고안은 유체 공급용의 게이트 밸브로서 유량조절은 물론 개폐가 가능함과 동시에 역류를 방지하는 체크밸브의 기능을 겸하게 된 것이어서 게이트밸브와 체크밸브를 동시부설해야하는 비경제적인 불편이 해소되고 좁은 설계 공간내에서의 집약적 설비에 매우 유용하게된 효과가 있는 것이다.As described above, the present invention is a gate valve for fluid supply, which allows the flow rate to be opened and closed, and at the same time serves as a check valve that prevents reverse flow, thereby eliminating the uneconomical inconvenience of installing the gate valve and the check valve simultaneously and narrowing the design. There is an effect that has become very useful for intensive equipment in space.
