[0027] Specifically, Figures 3 to 5 As shown, the valve body 1 includes a main valve 101, one end of the main valve 101 is provided with a water inlet channel 102, the other end of the main valve 101 is provided with a water outlet channel 103, the float control assembly 2 is connected to the water inlet channel 102, the upper end of the water inlet channel 102 is provided with a first installation position 1021, the lower end of the water inlet channel 102 is provided with a second installation position 1022, the first valve stem 302 is provided in the first installation position 1021, the second valve stem 304 is provided in the second installation position 1022, and the rubber-coated butterfly plate 301 is rotatably provided in the water inlet channel 102. In the channel 102, the worm gear actuator 303 is fixed above the first installation position 1021. The worm gear actuator 303 includes a handwheel, a worm and a worm wheel. Turning the handwheel causes the worm and the worm wheel to rotate, and the worm wheel drives the first valve stem 302 to rotate. The first valve stem 302 drives the rubber-coated butterfly plate 301 to rotate in the water inlet channel 102. The worm gear actuator 303 is used to drive the rubber-coated butterfly plate 301, so that the rubber-coated butterfly plate 301 has a self-locking ability, and the rubber-coated butterfly plate 301 can be stopped at any position, which is not easy to change and is more convenient to use.

[0028] The rubber-coated butterfly plate 301 is provided with a square groove 3011, and the plug-in end of the first valve stem 302 is arranged in the square groove 3011.

The first cavity 104 is provided above the sealed cavity 105, and the second cavity 106 is provided below the sealed cavity 105. The first cavity 104 A spring 11 is movably connected, a diaphragm gland 4 is provided below the spring 11, a diaphragm 5 is provided below the diaphragm gland 4, the diaphragm 5 is covered on the upper end surface of the sealing cavity 105 in a sealing manner, an upper valve disc 6 is provided in the sealing cavity 105, a lower valve disc 7 is provided below the upper valve disc 6, an O-ring 8 is provided between the upper valve disc 6 and the lower valve disc 7, a sealing ring 9 is provided below the lower valve disc 7, a sealing gland 10 is provided below the sealing ring 9, the sealing gland 10 is used to seal the lower end surface of the sealing cavity 105, the first cavity 104 is also provided with a connecting rod 12, the connecting rod 12 passes through the spring 11, the diaphragm gland 4, the diaphragm 5, the upper valve disc 6, the O-ring 8, the lower valve disc 7, the sealing ring 9 and the sealing gland 10 in sequence, a second ball valve 13 is provided on the side of the water inlet channel 102, the second ball valve 13 is connected to a pressure gauge 14, and the pressure gauge 14 is used to detect the water pressure value of the water inlet channel 102.

[0030] Water enters from the water inlet channel 102. After the water supply flow rate is adjusted by adjusting the control component 3 according to demand, a small part of the water enters the conduit 203, passes through the conduit 203 and flows to the first cavity 104 through the water inlet 202, and then flows from the first cavity 104 through the first ball valve 204, and finally flows out from the ball valve outlet 205, and then flows into the water tank from the ball valve outlet 205. Most of the water flows into the second cavity 106. Because the area of ​​the second cavity 106 is larger than that of the first cavity 104, when the second cavity 106 is full of water, the water pressure inside the second cavity 106 will be greater than the water pressure inside the first cavity 104. Under the action of the water pressure, the sealing cover 10 will move upward. When the sealing cover 10 moves upward, it drives the diaphragm 5 to move upward, so that the sealing cavity 105 is out of the sealed state, and the water in the second cavity 106 flows from the sealing cavity 105 to the water outlet channel 103, and then flows from the water outlet channel 103 to the water tank. The float 206 is placed in the water tank. When the water volume in the water tank reaches the specified water level, the float 206 rises under the action of the buoyancy of the water to close the ball valve outlet 205, and the ball valve outlet 205 stops discharging water, thereby causing the pressure inside the first cavity 104 in the valve cover 201 to be greater than the second cavity 106, so that the sealing cover 10 and the diaphragm 5 move downward and seal the upper and lower ends of the sealing cavity 105, thereby ensuring stable water supply.

[0031] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
