The clamping hole is convenient for the clamping rod 75 to be inserted to fix the sealing cover 74.

[0036] When this embodiment is in use: when water enters, it is filtered through the filter screen 73 in the filter box 71 and then enters. When the filter screen 73 needs to be cleaned or replaced, the clamping rod 75 is pulled, and the clamping rod 75 drives the clamping slider 76 to move and compress the clamping spring 77, so that the clamping rod 75 disengages from the clamping hole, and then the sealing cover 74 can be removed, so that the disassembly box 72 can be pulled out, and the filter screen 73 can be cleaned or replaced, so that when the device is in use, it is convenient to filter the water entering the valve, prevent impurities and sand from entering, causing malfunction in the valve, and improve the practicality of use.

[0037] The structure and use principle of the water level control valve body 1 and the control component 5 in the utility model have been disclosed in the hydraulic water level control valve disclosed in Chinese patent application number 202121097626.0. Its working principle is that the user manually installs the float in the float chamber tube, and the flip rod is rotatably connected to the connecting column through the flip shaft. The flip shaft is connected to the valve stem in the outer valve, and the sealing plug extends into the control valve. Then the water inlet pipe 6 is fixedly connected to the external water pumping pipe through the first flange, and the water outlet pipe 8 is fixedly connected to the water tank through the second flange. The float chamber tube extends vertically into the water tank, and the float moves stably up and down in the float chamber tube according to the change of water content in the water tank, thereby coordinating the up and down movement of the valve stem to control the filling of water into the water tank.

[0038] Working principle and use process of the utility model: the utility model is used to control the water level. When in use, the sealing gasket 4 between the valve cover 3 and the assembly 2 is conveniently disassembled to facilitate sealing between them to prevent leakage during pumping and affect the surrounding environment. When in use, the incoming water can be filtered through the filter assembly 7 to prevent the entry of impurities and sand particles. When the valve cover 3 needs to be opened for maintenance and replacement of internal components, the valve cover 3 can be quickly opened and closed through the convenient disassembly assembly 2. When the convenient disassembly assembly 2 is in use, the pull rod 23 is pulled, and the pull rod 23 drives the fixed slider 24 to move and compress the fixed spring 25, so that the fixed block 22 is disengaged from the fixed hole, and then the valve cover 3 and the water level control valve body 1 can be separated. When the pull rod 23 moves to the limit hole and coincides with the limit rod 231, the limit spring 233 is reset, driving the limit rod 231 to insert into the limit hole. The pull rod 23 is limited and fixed in the hole to prevent it from rebounding. The roller 234 facilitates smooth sliding between the pull rod 23 and the limit rod 231, so that the device can quickly open and close the valve cover 3 when in use, and maintain and replace the internal components, thereby improving the practicality of use. When the filter assembly 7 is in use, when water enters, it is filtered through the filter screen 73 in the filter box 71, and then enters. When the filter screen 73 needs to be cleaned or replaced, the clamping rod 75 is pulled, and the clamping rod 75 drives the clamping slider 76 to move and compress the clamping spring 77, so that the clamping rod 75 disengages from the clamping hole, and then the sealing cover 74 can be removed, thereby pulling out the disassembly box 72, and cleaning or replacing the filter screen 73, so that when the device is in use, it is easy to filter the water entering the valve, prevent impurities and sand from entering, causing malfunction in the valve, and improve the practicality of use.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
