Detailed Description
As shown in fig. 1-2, for the flat gate valve for oil extraction device of the present invention, the flat gate valve comprises a valve body 1, an end cover 2 and a flow channel 3 for medium circulation, a cavity 4 communicated with the flow channel 3 is arranged in the valve body 1, a valve plate 5 is arranged in the cavity 4, one end of the valve plate 5 is connected with a valve rod 7 through a bearing 6, the valve rod 7 passes through the end cover 2 and is connected with the end cover 2 through a thread, and a hand wheel 8 connected with the valve rod 7 is arranged outside the valve body 1; the outer part of the valve plate 5 is provided with a tensioning piece, the tensioning piece comprises a sliding rod 9, the sliding rod 9 is fixedly connected with the valve plate 5 and is abutted against the valve body 1, the end part of the sliding rod 9 is provided with an elastic sealing gasket 10 with an inclined plane, the bottom of the valve body 1 connected with the cavity 4 is matched with the elastic sealing gasket 10, and a spring 11 fixed with the elastic sealing gasket 10 is arranged in the elastic sealing gasket 10; a guide device for the elastic sealing gasket 10 to slide is arranged in the flow channel 3, the guide device is communicated with the flow channel 3, a sealing space 12 is arranged on the valve body 1, and two sides of the sealing space 12 are matched with the inclined plane of the elastic sealing gasket 10.
Specifically, when the medium flow channel 3 is closed, the hand wheel 8 is rotated, the valve rod 7 is rotated, the bearing 6 drives the valve plate 5 to descend, the elastic sealing gasket 10 at the end part of the valve plate 5 slides and penetrates through the guide device, in the sliding process, the elastic sealing gasket 10 compresses the spring 11 and is in a tension state until sliding into a sealing space, the sealing space 12 is provided with an inclined plane matched with the elastic sealing gasket 10, so that the whole body is wider than the sliding space in the guide device, finally, under the action of the spring 11, the elastic sealing gasket 10 expands and abuts against the valve body 1 in the sealing space 12, the rod 9 falls into the flow channel 3 (the length of the rod is larger than the width of the sealing space 12 of the flow channel 3) to form sealing, the situation that the traditional valve rod is directly contacted with the valve body in a horizontal plane and has a horizontal gap, so that the sealing is poor is caused is changed, the sealing space 12 in the shape of a, and adopt the elastic sealing gasket 10 to seal, even if there is water also will fall into the sealed space 12 along the elastic sealing gasket 10, has improved the sealed effect, when needing to open the medium runner 3, the hand wheel 8 of reverse rotation can, because the valve block 1 and the elastic sealing gasket 10 all have inclined planes, so when rising, can not form the hindrance.
The guiding device comprises a filter screen 13, two ends of the filter screen 13 are fixedly connected with the valve body 1, one end of the filter screen 13 is connected with the cavity 4, the other end of the filter screen is connected with the sealing space 12, on one hand, the filter screen 13 is provided with a through hole, when the flow channel 3 is opened, a medium can pass through the through hole, on the other hand, impurities in the medium can be intercepted, and meanwhile, the elastic sealing gasket 10 can provide a guiding effect when sliding.
In addition, valve body 1 that is connected with cavity 4 inlays in vertical direction and is equipped with a plurality of graphite blocks 14, the terminal surface of graphite block 14 flushes mutually with the terminal surface of valve body 1 to can offset with slide bar 9, when valve rod 7 drove 5 slides many times of valve plate, slide bar 9 contacted with valve body 1, can produce friction and wearing and tearing, and at valve body 1 embedded graphite block 14, because graphite block 14 has the effect of self-lubricating, make slide bar 9 slide more smoothly, reduce wearing and tearing, further can improve sealing performance.
The above is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions or modifications made on the basis of the present invention to solve the same technical problems and achieve the same technical effects are all covered by the protection scope of the present invention.
