[0002] A valve is a device used to control the direction, pressure, and flow of a fluid in a fluid system. It is a device that allows the medium (liquid, gas, powder) in pipes and equipment to flow or stop and control its flow. It is widely used in the field of oil extraction.

[0003] In the prior art, the patent number is CN114001196A, and the name is a fully enclosed high-temperature and high-pressure oil production valve, comprising a valve main valve body, a fixed valve seat is fixedly installed on the upper surface of the valve main valve body, a valve connecting pipe is fixedly installed on the upper surface of the fixed valve seat, a liquid inlet pipe is fixedly installed on one side surface of the valve main valve body, a secondary square bin body is fixedly installed on the other side surface of the valve main valve body, a liquid outlet pipe is fixedly installed on one side surface of the secondary square bin body, and a pressure chamber and a sealing chamber are arranged inside the secondary square bin body; the present invention can monitor the closing status of the valve main valve body. When the valve main valve body is not tightly closed and a slight leakage occurs, the sealing sliding pad moves up, and the change amount is displayed through the indicator line interlayer and the indicator scale, so as to facilitate the detection of slight leakage of the valve main valve body and improve the sensitivity and usability of the valve.

The second sealing plate 10 is held on the surface of the pipe 2 to play a sealing role, and the lifting block 13 moves downward with the first lifting rod 7 into the interior of the first lifting groove 14. When the valve body 1 leaks, the liquid enters the interior of the first lifting groove 14 and enters the second lifting groove 20 through the through groove 19. The liquid causes the floating block 21 to float, and the floating block 21 drives the second lifting rod 7 to move downward. The second lifting rod 17 moves upward, and a scale 18 is provided on the surface of the second lifting rod 17. The scale 18 can be used to detect whether the valve body 1 is leaking. After the rotating rod 16 moves upward, the supporting ring 28 no longer supports the surface of the force-bearing block 26, so that the telescopic block 24 enters the telescopic groove 25 under the pull of the spring 34, and the adsorption rod 30 is adsorbed on the surface of the magnet 31, so that the telescopic block 24 is stable in the telescopic groove 25, and the screw rod 22 is no longer screwed in the screw hole 23. The second lifting rod 17 can move freely, and the floating block 21 will not be affected when floating.
