The two parallel and coinciding filter screens 18 can filter the liquid flowing inside the valve and block the filtered matter outside the valve. When the staff installs the filter screen 18, they should ensure that the concave side of the filter screen 18 Facing the direction of water flow, the staff can insert the fixing rings 19 on the side walls of the two filters 18 into the fixing grooves 26 at both ends of the connecting pipe 1 respectively. As the connecting pipe 1 and the external pipe 3 are aligned and the first fixing platform 5 and the second fixing platform 6 are closed, the exposed part of the fixing ring 19 will automatically enter the fixing groove 26 at the end of the external pipe 3. The two fixing grooves 26 will eventually completely wrap the fixing rings 19 at the ends of the filter 18 to achieve the fixation of the filter 18. When water flows through, the sealing rubber ring 20 fixed to the side wall of the filter 18 can block the gap between the filter 18 and the connecting pipe 1, and the gap between the filter 18 and the external pipe 3 to ensure that the water flow can always receive the filtration of the filter 18. Whenever the valve is blocked, the staff can open the valve to clean the blockage. This step achieves filtration of the flowing liquid by arranging the filter 18 between the connecting pipe 1 and the external pipe 3, and at both ends of the connecting pipe 1, thereby achieving the effect of anti-blockage, which is conducive to concentrating the blockage and treating it in a centralized manner, avoiding the situation where the blockage cannot be cleaned when it is spread.

During the working process, whenever the rotating block 13 at the top of the movable rod 11 rotates, due to the threaded connection between the top of the movable rod 11 and the rotating block 13, and the limit block 12 fixed to the side wall of the movable rod 11 is restricted by the limit box 10, the movable rod 11 will move in the vertical direction, and drive the two disc valve plates 17 inside the connecting pipe 1 to move in the vertical direction synchronously. Whenever the two disc valve plates 17 are damaged, or the other components inside the control valve pipe 2 are damaged, the staff will open the first screw 22 and the nut 25 at the same time to separate the second fixing platform 6 at the top of the control valve pipe 2 from the second fixing platform 6 at the top of the spherical protrusion 4, and then the damaged components can be processed. This step controls the opening and closing state of the valve by setting the movable rod 11, and blocks the water flow by two parallel disc valve plates 17, which is conducive to solving the problem of loose valve closure, improving the sealing performance of the valve, and making the valve control more efficient and flexible.

[0026] like Figures 1 to 3 As shown, a second screw 23 is provided at the end of the first fixing platform 5, and multiple second screws 23 are distributed in a circular array; a spring 24 is fixed between the second screw 23 and the first fixing platform 5; a nut 25 is provided at the end of the second screw 23 away from the first fixing platform 5; during operation, after the first fixing platform 5 at the end of the connecting pipe 1 and the second fixing platform 6 at the end of the external pipe 3 are completed, the multiple springs 24 can apply stress to the second screw 23 and the first fixing platform 5 to increase the pressure between the first fixing platform 5 and the second fixing platform 6, and finally make the connection between the connecting pipe 1 and the external pipe 3 tighter; this step applies stress to the connecting pipe 1 and the external pipe 3 by arranging the second screw 23 and the spring 24 between the first fixing platform 5 and the second fixing platform 6, thereby achieving a tight connection between the two, which is beneficial to solving the problem of loose connection between the connecting pipe 1 and the external pipe 3 and enhancing the leak-proof ability of the connection between the valve and the pipe.

[0027] like Figure 3 As shown, a first sealing ring 7 is fixedly connected to the top of the second fixing platform 6 located at the top of the valve control tube 2, and a second sealing ring 8 is fixedly connected to the bottom of the second fixing platform 6 located at the bottom of the spherical protrusion 4, and the first sealing ring 7 and the second sealing ring 8 are arranged correspondingly; during operation, whenever the two second fixing platforms 6 are fixed by the first screw 22 and the nut 25, the first sealing ring 7 and the second sealing ring 8 are respectively squeezed between the two second fixing platforms 6, and the two are in close contact with each other to prevent water leakage; this step enhances the airtightness of the valve by arranging the first sealing ring 7 and the second sealing ring 8, which is conducive to solving the problem of liquid leakage from the top of the valve control tube 2 and enhancing the stability of the valve.

[0028] like Figure 3 As shown, a fixing plate 16 is fixed between the two disc valve plates 17, and the top of the fixing plate 16 is fixed to the bottom of the connecting block 15; during operation, whenever the movable rod 11 moves, the connecting block 15 and the two disc valve plates 17 will move synchronously. With the help of the connection of the fixing plate 16, the two disc valve plates 17 can jointly bear the impact and pressure from the water body; this step connects the two disc valve plates 17 into one by fixing the fixing plate 16 between the two disc valve plates 17, which is conducive to solving the problem of uneven force on the two disc valve plates 17 and enhancing the stability of the valve.

[0029] like Figure 4 As shown, the two ends of the connecting pipe 1 are fixedly connected with a bearing platform 21, and the end of the external pipe 3 is fixedly connected with a bearing platform 21, and the two bearing platforms 21 are set correspondingly; during work, after the staff completes the docking of the connecting pipe 1 with the external pipe 3, the two bearing platforms 21 located at the ends of the connecting pipe 1 and the external pipe 3 will be in close contact. Through the close contact of the two bearing platforms 21, the contact area of ​​the connection between the connecting pipe 1 and the external pipe 3 will be reduced, thereby increasing the pressure at the contact point; this step increases the pressure at the contact part between the connecting pipe 1 and the external pipe 3 by setting a fixed groove 26, thereby achieving a good connection effect and enhancing the anti-leakage ability of the valve.

[0030] like Figure 1 As shown, the side wall of the handle 14 is provided with an anti-slip cover; during work, the handle 14 equipped with the anti-slip cover can enhance the friction on the surface of the handle 14; this step enhances the friction by providing the anti-slip cover on the surface of the handle 14, reduces the occurrence of slipping, and provides convenience for the staff.

[0031] During operation, when water flows through the valve, it always passes through the external pipe 3, the connecting pipe 1 and the external pipe 3 on the other side. The two parallel and coinciding filter screens 18 can filter the liquid flowing inside the valve and block the filtered matter outside the valve. When the staff installs the filter screen 18, they should ensure that the concave side of the filter screen 18 faces the direction of water flow. The staff can insert the fixing rings 19 on the side walls of the two filter screens 18 into the fixing grooves 26 at both ends of the connecting pipe 1. As the connecting pipe 1 and the external pipe 3 are aligned and the first fixing platform 5 and the second fixing platform 6 are closed, the exposed part of the fixing ring 19 will automatically enter the fixing groove 26 at the end of the external pipe 3. The two fixing grooves 26 will eventually complete the fixing ring 19 at the end of the filter screen 18. The filter screen 18 is fully wrapped inside to fix the filter screen 18. When water flows through, the sealing rubber ring 20 fixed to the side wall of the filter screen 18 can block the gap between the filter screen 18 and the connecting pipe 1, and the gap between the filter screen 18 and the external pipe 3 to ensure that the water flow can always be filtered by the filter screen 18. Whenever the valve is blocked, the staff can open the valve to clean the blockage. The staff can use the handle 14 to rotate the rotating block 13 relative to the fixed block 9, thereby controlling the height of the two disc valve plates 17 inside the connecting pipe 1, so as to achieve control of the valve. During operation, whenever the rotating block 13 at the top of the movable rod 11 rotates, due to the threaded connection between the top of the movable rod 11 and the rotating block 13, and the limit block 12 fixed to the side wall of the movable rod 11 Restricted by the limit box 10, the movable rod 11 will move in the vertical direction and drive the two disc valve plates 17 inside the connecting pipe 1 to move in the vertical direction synchronously. Whenever the two disc valve plates 17 are damaged or the other components inside the control valve pipe 2 are damaged, the staff will open the first screw 22 and the nut 25 to separate the second fixing platform 6 at the top of the control valve pipe 2 from the second fixing platform 6 at the top of the spherical bump 4, and then the damaged components can be processed. After the first fixing platform 5 at the end of the connecting pipe 1 is connected to the second fixing platform 6 at the end of the external pipe 3, the multiple springs 24 can apply stress to the second screw 23 and the first fixing platform 5 to increase the pressure between the first fixing platform 5 and the second fixing platform 6, and finally make the connecting pipe 1 The connection with the external pipe 3 is tighter. Whenever the two second fixing platforms 6 are fixed by the first screw 22 and the nut 25, the first sealing ring 7 and the second sealing ring 8 are respectively squeezed between the two second fixing platforms 6, and the two are in close contact with each other to prevent water leakage. Whenever the movable rod 11 moves, the connecting block 15 and the two disc valve plates 17 will move synchronously. With the help of the connection of the fixing plate 16, the two disc valve plates 17 can jointly bear the impact and pressure from the water body. After the staff completes the docking of the connecting pipe 1 with the external pipe 3, the two bearing platforms 21 at the ends of the connecting pipe 1 and the external pipe 3 will be in close contact. Through the close contact of the two bearing platforms 21, the contact area of ​​the connection between the connecting pipe 1 and the external pipe 3 will be reduced.The handle 14 equipped with the anti-slip sleeve can increase the friction force on the surface of the handle 14, thereby increasing the pressure at the contact point.
