[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-3, a water pump control valve of the present invention includes a control valve body 1, a conduit 2 and a transfer tube 3 are provided at the liquid inlet end of the control valve body 1, a frame 4 is provided between the conduit 2 and the transfer tube 3, a filter plate 5 is provided inside the frame 4, a plurality of positioning blocks 7 are provided on the inner wall of the conduit 2, the inner side of the frame 4 can contact the positioning blocks 7, a limiting ring 9 is fixedly provided on the inner wall of the conduit 2, and the limiting ring 9 can contact the outer side of the frame 4, a plurality of limiting sleeves 12 are symmetrically provided on the circumference of the conduit 2, a plurality of limiting rods 11 penetrating the limiting sleeves 12 are provided on the circumference of the transfer tube 3, a side block 13 is fixedly provided on one side of the transfer tube 3, a screw 14 is rotatably provided on one side of the conduit 2, the screw 14 can penetrate the side block 13, and the screw 14 is threadedly connected to the side block 13;

[0022] In this structure, the positioning block 7 can limit the frame 4, so that the filter plate 5 can be installed inside the conduit 2. The cooperation between the limiting rod 11 and the limiting sleeve 12 can provide a positioning effect between the conduit 2 and the transfer tube 3, which can facilitate the docking of the conduit 2 and the transfer tube 3. By rotating the screw 14, since the position of the screw 14 is fixed, the side block 13 can be moved along the screw 14 until the conduit 2 and the transfer tube 3 are docked. The filter plate 5 can provide a filtering effect for the liquid inlet end of the control valve body 1, and can filter impurities in the water, so that the impurities in the water will not enter the water pump, and it is not easy to damage the water pump, thereby increasing the service life of the water pump.

[0023] When the filter plate 5 needs to be disassembled, the conduit 2 and the transfer tube 3 can be separated, which has a simple structure and is easy to operate.

[0024] In this structure, a sealing ring 15 is provided between the conduit 2 and the transfer tube 3 . The sealing ring 15 can be a rubber ring, which can ensure the sealing between the conduit 2 and the transfer tube 3 .

[0025] In this structure, a limit block 10 is provided on the outside of the limit sleeve 12, and the limit block 10 is penetrated by the limit rod 11, and the limit block 10 is threadedly connected to the limit rod 11.
