본 고안에 의한 더블 파일로트 밸브 붙이 버터플라이밸브의 누수차단장치는 밸브가 관로에 설치되어 밸브 본체(100)에 축착된 디스크(200)가 관로를 개폐하게 되며, 디스크(200)가 관로를 폐쇄한 경우, 관로의 상류측, 즉 도 4를 기준으로 우측부에서 수압이 작용하게 되면 본체 시트링(310)이 상류측 단부는 낮고 하류측 단부는 높은 형태로 경사지게 결합되고, 디스크(200)의 디스크 시트링(410)도 같은 형태로 형성되어 있으므로 디스크(200)에 고정된 디스크 시트링(410)의 경사면(411)이 밸브 본체(100)에 결합된 본체 시트링(310)의 경사면(312)에 긴밀하게 압착된다.In the leak shutoff device of the butterfly valve with a double pilot valve according to the present invention, the valve is installed in the pipeline so that the disk 200 condensed on the valve body 100 opens and closes the pipeline, and the disk 200 closes the pipeline. In one case, when the hydraulic pressure acts on the upstream side of the conduit, that is, on the right side with reference to FIG. 4, the main body seat ring 310 is inclinedly coupled in a low form at an upstream end and at a downstream end in a high form. Since the disc seat ring 410 is formed in the same shape, the inclined surface 411 of the disc seat ring 410 fixed to the disc 200 is inclined surface 312 of the body seat ring 310 coupled to the valve body 100. Tightly pressed).
그리고, 디스크(200)에 형성된 유통로(250)의 상류측에 결합된 파일로트 밸브(270)의 통수공(283)으로 수압이 작용하여 개폐볼(290)이 스프링(291)의 힘을 이기고 내측으로 이동하여 밸브실(282)이 개방되며, 이에 따라 상류측 수압이 유통로(250)와 연통로(260)를 통하여 시트 고정홈(230)의 수압 작용부(232)에 작용하고 고무재 디스크 시트링(410)이 수압에 의해 반경방향 외측으로 밀리면서 디스크 시트링(410)의 경사면(411)이 본체 시트링(310)의 경사면(312)에 더욱 긴밀하게 압착되어 누수가 완벽하게 차단된다.Then, the hydraulic pressure acts on the water supply hole 283 of the pilot valve 270 coupled to the upstream side of the flow path 250 formed in the disk 200 so that the opening / closing ball 290 overcomes the force of the spring 291. The valve chamber 282 is opened by moving inward, so that the upstream hydraulic pressure acts on the hydraulic acting portion 232 of the seat fixing groove 230 through the flow passage 250 and the communication passage 260 and the rubber material. As the disc seat ring 410 is pushed radially outward by the hydraulic pressure, the inclined surface 411 of the disc seat ring 410 is pressed more tightly to the inclined surface 312 of the main body seat ring 310 to completely block leakage. do.
한편, 관로의 하류측, 즉 도 5를 기준으로 좌측부에서 수압이 작용하게 되면 디스크(200)에 형성된 유통로(250)의 하류측에 결합된 파일로트 밸브(270)의 통수공(283)으로 수압이 작용하여 개폐볼(290)이 스프링(291)의 힘을 이기고 내측으로 이동하여 밸브실(282)이 개방되며, 이에 따라 상류측 수압이 유통로(250)와 연통로(260)를 통하여 시트 고정홈(230)의 수압 작용부(232)에 작용하고 고무재 디스크 시트링(410)이 수압에 의해 반경방향 외측으로 밀리면서 디스크(200)에 고정된 디스크 시트링(410)의 경사면(411)이 밸브 본체(100)에 결합된 본체 시트링(310)의 경사면(312)에 긴밀하게 압착되어 누수가 완벽하게 차단된다.On the other hand, when the hydraulic pressure acts on the downstream side of the pipe, that is, on the left side with reference to FIG. 5, to the water passage 283 of the pilot valve 270 coupled to the downstream side of the flow path 250 formed on the disk 200. The hydraulic pressure acts so that the opening / closing ball 290 moves inward to overcome the force of the spring 291, and the valve chamber 282 is opened, whereby the upstream hydraulic pressure passes through the flow passage 250 and the communication passage 260. The inclined surface of the disk seat ring 410 fixed to the disk 200 while acting on the hydraulic acting portion 232 of the seat fixing groove 230 and the rubber disk seat ring 410 is pushed radially outward by the hydraulic pressure ( 411 is tightly pressed against the inclined surface 312 of the body seat ring 310 coupled to the valve body 100 to completely prevent leakage.
이상에서 설명한 바와 같은 본 고안에 의한 더블 파일로트 밸브 붙이 버터플라이밸브의 누수차단장치는 Leakage blocking device of the butterfly valve with double pilot valve according to the present invention as described above
관로에 설치되는 밸브 본체의 내부에 디스크가 관로를 개폐하기 위하여 회전 가능하게 설치되고, 상기 밸브 본체의 내주면에는 본체 시트링이 고정되고, 상기 디스크의 외주면에는 디스크 시트링이 고정된 버터플라이밸브의 누수차단장치에 있어서, 상기 디스크의 외주연부에 관로의 수압이 작용하는 유통로가 폭방향으로 형성되고, 상기 시트 고정홈 선단의 수압 작용부와 상기 유통로를 연통시키는 연통로가 반경방향으로 형성되며, 상기 유통로의 양단부에는 수압에 의해 개방되는 파일로트 밸브가 각각 결합되어 구성된 것으로, 관로의 상,하류측 양방향에서 작용하는 수압에 대해 디스크 시트링이 본체 시트링 측으로 밀려 긴밀하게 압착됨으로써 상,하류측 양방향으로 누수를 완벽하게 차단할 수 있는 이점이 있다.In the valve body installed in the conduit, the disk is rotatably installed to open and close the conduit, the inner circumferential surface of the valve body is fixed to the body seat ring, the outer circumferential surface of the disk of the butterfly valve is fixed In the water leakage blocking device, a flow path in which the hydraulic pressure of the pipe is applied to the outer periphery of the disk is formed in the width direction, and a communication path is formed in the radial direction to communicate the hydraulic pressure acting portion of the seat fixing groove tip with the flow path. The pilot valve which is opened by hydraulic pressure is coupled to both ends of the flow passage, respectively, and the disc seating is pushed to the main body seating side against the water pressure acting in both the upstream and downstream sides of the pipeline, There is an advantage that the leakage can be completely blocked in both directions downstream.
