DETAILED DESCRIPTION

[0016] See also Figure 1-Figure 4 The utility model provides the following technical solutions: a hydraulic valve, including a hydraulic ball valve seat 1 and a hydraulic ball valve ball 11, the inner wall of the bottom end of the hydraulic ball valve ball 11 is provided with a horizontal filling surface 12, the inner wall of the hydraulic ball valve ball 11 is fixedly connected with a filter support frame 2, a filter assembly 3 is provided on one side of the filter support frame 2, the filter assembly 3 includes a filter screen plate 31 and an elastic support ring 32, the elastic support ring 32 is fixedly connected to the side wall of the filter screen plate 31, the side wall of the hydraulic ball valve seat 1 is fixedly connected with a slag discharge pipe 4, and the slag discharge pipe 4 corresponds to the horizontal position of the horizontal filling surface 12.

[0017] In this embodiment: during normal use, the filter screen plate 31 is opened under the elastic force of the elastic support ring 32, and the filter screen plate 31 and the elastic support ring 32 are attached to the side wall of the filter screen support frame 2 to filter impurities in the liquid. When the impurities need to be removed, the staff closes the valve, and the opening of the hydraulic ball valve ball 11 turns to the side wall of the hydraulic ball valve seat 1. The staff opens the flushing pipe 41, and the filter screen support frame 2 is separated from the filter screen plate 31 and the elastic support ring 32. The elastic support ring 32 itself can be elastically deformed. Before the liquid in the hydraulic ball valve seat 1 is discharged, the staff reaches into the hydraulic ball valve ball 11 through a traction tool such as a hook, and after connecting the traction hook ring 34, the filter screen plate 31 and the elastic support ring 32 are reciprocated. The liquid repeatedly flows through the filter screen plate 31, and the impact force of the water flow is used to separate the liquid. The impurities attached to the filter screen plate 31 are separated from the impurities. The horizontal filling surface 12 prevents the impurities intercepted by the filter assembly 3 and the filter screen plate 31 from settling in the concave surface of the hydraulic ball valve sphere 11. Then the staff opens the slag discharge pipe 4, and the liquid in the hydraulic ball valve sphere 11 is discharged through the slag discharge pipe 4, carrying away some impurities. The staff simultaneously injects cleaning liquid into the hydraulic ball valve sphere 11 through the flushing pipe 41, and flushes the intercepted impurities through the slag discharge pipe 4 to the outside of the hydraulic ball valve seat 1 through the water flow. In the process of cleaning the impurities in the hydraulic ball valve seat 1 and the hydraulic ball valve sphere 11, there is no need to disassemble the valve body, which makes it more convenient to clean the impurities in the hydraulic ball valve seat 1 and the hydraulic ball valve sphere 11. Moreover, through the cooperation of various structures, it is difficult for impurities to remain during the cleaning process, and the impurities are removed more thoroughly.

[0018] A sealing gasket 13 is fixedly connected to the inner wall of the hydraulic ball valve seat 1, and the top height of the sealing gasket 13 corresponds to the position of the horizontal filling surface 12; the sealing gasket 13 is aligned with the bottom position of the hydraulic ball valve ball 11. By providing the sealing gasket 13, the bottom gap between the hydraulic ball valve ball 11 and the hydraulic ball valve seat 1 can be filled, so that impurities will not fall into the gap during use and cleaning, and the removal of impurities is more thorough.

[0019] A traction connecting rod 33 is fixedly connected to the inner wall of the elastic support ring 32, and the ends of several traction connecting rods 33 are fixedly connected, and the ends of several traction connecting rods 33 have traction hook rings 34; by providing the traction connecting rod 33 and the traction hook ring 34, the staff can use a hook or other tool to connect to the outside of the hydraulic ball valve seat 1 to drive the filter screen 31 and the elastic support ring 32 to move. When the staff pulls the traction connecting rod 33 and the traction hook ring 34 to move, the traction connecting rod 33 pulls the elastic support ring 32, driving the elastic support ring 32 to bend and contract, so that the filter screen 31 and the elastic support ring 32 can move in the hydraulic ball valve ball 11.

[0020] The outer wall of the outermost elastic support ring 32 is fixedly connected with a sealing interception ring 321, and the sealing interception ring 321 is in contact with the inner wall of the hydraulic ball valve ball 11; by providing the sealing interception ring 321, the gap between the elastic support ring 32 and the inner wall of the hydraulic ball valve ball 11 can be blocked to prevent impurities from flowing into the rear pipeline through the gap between the elastic support ring 32 and the inner wall of the hydraulic ball valve ball 11.

[0021] A flushing pipe 41 is fixedly connected to the side wall of the hydraulic ball valve seat 1. The flushing pipe 41 is located above the slag discharge pipe 4. The openings of the slag discharge pipe 4 and the flushing pipe 41 are both detachably connected with sealing plugs 42; the position of the slag discharge pipe 4 is lower than the position of the horizontal filling surface 12, so that impurities can flow out along with the water flow, and the position of the flushing pipe 41 is located at a high place, corresponding to the middle position of the filter screen plate 31 and the elastic support ring 32, which is more convenient when adjusting the angle of the extension into the pipe, so that personnel can easily flush the filter screen plate 31 with the help of water flow.

[0022] The working principle and use process of the utility model are as follows: in normal use, the filter screen plate 31 is opened under the elastic force of the elastic support ring 32, and the filter screen plate 31 and the elastic support ring 32 are attached to the side wall of the filter screen support frame 2 to filter impurities in the liquid. When it is necessary to remove impurities, the staff closes the valve, and the opening of the hydraulic ball valve ball 11 turns to the side wall of the hydraulic ball valve seat 1. The staff opens the flushing pipe 41, and the staff reaches into the hydraulic ball valve ball 11 through a traction tool such as a hook, and after connecting the traction hook ring 34, the staff The filter screen plate 31 and the elastic support ring 32 are pulled to reciprocate, and the liquid repeatedly flows through the filter screen plate 31. The impurities attached to the filter screen plate 31 are separated by the impact force of the water flow, and the impurities are settled on the top of the horizontal filling surface 12. Then the staff opens the slag discharge pipe 4, and the liquid in the hydraulic ball valve ball 11 is discharged through the slag discharge pipe 4, and some impurities are carried out. At the same time, the staff injects cleaning liquid into the hydraulic ball valve ball 11 through the flushing pipe 41, and the intercepted impurities are flushed to the outside of the hydraulic ball valve seat 1 through the slag discharge pipe 4 by the water flow.
