Figure 4 Figure 6 ​​The filtering assembly comprises a filtering plate 12 for filtering impurities in fluid, a side wall of the filtering plate 12 is slidingly connected in the valve body 1, a fixed rod 13 is fixedly connected to the side wall of the filtering plate 12, a sealing gasket 14 is fixedly connected to the side wall of the filtering plate 12, a recess 15 is arranged in the filtering plate 12, a vertical groove 16 is arranged in the valve body 1, a fixed column 17 is arranged in the valve body 1, a side wall of the fixed column 17 is fixedly connected in the vertical groove 16, a connecting column 18 is slidingly connected in the fixed column 17, a side wall of the connecting column 18 is fixedly connected with a clamping block 19, the clamping block 19 is used for fixing the filtering plate 12, a side wall of the clamping block 19 is slidingly connected in the vertical groove 16, a side wall of the clamping block 19 is slidingly connected in the vertical groove 16, a second spring 20 is sleeved on the side wall of the connecting column 18, one end of the second spring 20 is fixedly connected to the side wall of the fixed column 17, and the other end of the second spring 20 is fixedly connected to the side wall of the clamping block 19.

[0038] The filtering plate 12 in the valve body 1 is used for filtering impurities in fluid, preventing the impurities from entering the pipeline system and affecting the equipment operation. In long-term use, the filtering plate 12 will be blocked by impurities, affecting the filtering effect. During maintenance, the fixed rod 13 is pulled to drive the filtering plate 12 to move. When the filtering plate 12 moves, the clamping block 19 is extruded into the vertical groove 16 arranged in the valve body 1. The clamping block 19 extrudes the connecting column 18 in the process, so that the connecting column 18 slides in the fixed column 17. Meanwhile, the movement of the clamping block 19 extrudes the second spring 20 to make it contract. The second spring 20 also plays a buffering and resetting role. When the external force of the clamping block 19 disappears, it can be reset.

[0039] Working principle: The stop valve needs to be maintained and replaced after long-term use. First, the nut 11 is rotated to be removed, so that the connection of the valve body 1 and the connecting pipe 3 is cancelled. Then, the lever 8 is rotated to drive the clamping column 10 to slide in the fixed frame 4. When the lever 8 moves, the connecting rod 7 is extruded to slide in the sleeve 6. Meanwhile, the movement of the lever 8 extrudes the first spring 9 to make it contract. With the movement of the clamping column 10, the connection of the connecting pipe 3 is cancelled, and the connecting pipe 3 is taken down for maintenance and replacement of the valve body 1 and the connecting pipe 3.

[0040] The filtering plate 12 in the valve body 1 will be blocked in long-term use. During maintenance, the fixed rod 13 is pulled to drive the filtering plate 12 to move. When the filtering plate 12 moves, the clamping block 19 is extruded into the vertical groove 16 arranged in the valve body 1. The clamping block 19 extrudes the connecting column 18 to make it slide in the fixed column 17. Meanwhile, the movement of the clamping block 19 extrudes the second spring 20 to make it contract. With the clamping block 19 separated from the recess 15, the fixing of the filtering plate 12 is cancelled, so that the filtering plate 12 can be taken out for cleaning.

[0041] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
