A valve is usually composed of a valve body, a valve cover, a valve seat, an opening and closing member, a driving mechanism, a seal, and fasteners. The control function of the valve is achieved by driving the opening and closing member to rise and fall, slide, swing, or change the size of the flow area by the driving mechanism or fluid to change the rotation ratio. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves, chrome-molybdenum steel valves, chrome-molybdenum-vanadium steel valves, duplex steel valves, plastic valves, non-standard custom valve materials, etc. Precision water control devices are a type of equipment used to monitor and regulate water flow, usually used in irrigation systems or water treatment equipment.

When the flow rate of water is too large, the buoyancy of the water will cause the float 9 to move on the surface of the limiting shaft 8, thereby increasing the flow rate of water. Subsequently, the float 9 will lift the movable plate 12, and the movement of the movable plate 12 will drive the first sealing plate 13 and the second sealing plate 15 to move, and under the action of the buffer mechanism 11, the movable plate 12 will have a vibration reduction and limiting effect. At this time, excess water can be discharged through the third valve port 4, thereby achieving the effect of water control.

[0028] Specifically, a water level observer 5 is installed on the surface of the water control valve 1 , and a transparent observation plate is provided on the surface of the water level observer 5 .

[0029] In a specific embodiment of the present utility model, the water level height inside the water control valve 1 can be observed by providing the water level observer 5, so that the user can conveniently record the water flow height.

[0030] Specifically, the connection mechanism 6 includes a connection block 601 installed on the surface of the water control valve 1 , a fixing bolt 602 is rotatably connected to the surface of the connection block 601 , and a fixing nut 603 is threadedly connected to the surface of the fixing bolt 602 .

[0031] In a specific embodiment of the present utility model, the connecting block 601 can be fitted with other connecting pipes, and the connecting pipes can be tightened by rotating the fixing nut 603 on the surface of the fixing bolt 602, thereby achieving a connection effect.

[0032] Specifically, a plurality of first sealing rings 10 are arranged on the surface of the float 9 , and the size of the first sealing rings 10 is adapted to the inner wall of the water control valve 1 .

[0033] In a specific embodiment of the utility model, by disposing the first sealing ring 10 , the water control valve 1 can be blocked when the float 9 does not move, thereby reducing the probability of water flowing out through the third valve port 4 .

[0034] Specifically, the first sealing plate 13 and the second sealing plate 15 are adapted to the inner wall of the water control valve 1 , and the movable plate 12 is adapted to the inner wall of the water control valve 1 .

[0035] In a specific embodiment of the utility model, by adapting the first sealing plate 13 and the second sealing plate 15 to the inner wall of the water control valve 1, the airtightness of the third valve port 4 when not in use can be increased. At the same time, the movable plate 12 adapts to the inner wall of the water control valve 1, and the inner wall of the water control valve 1 can be further sealed.

[0036] Specifically, the buffer mechanism 11 includes a mounting cylinder 1101 installed at the bottom of the threaded block 7, the inner wall of the mounting cylinder 1101 is slidably connected with a buffer cylinder 1102, the inner wall of the mounting cylinder 1101 is installed with a damper 1103, and the top end of the damper 1103 is fixedly connected to the inner wall of the buffer cylinder 1102, and the surface of the damper 1103 is installed with a buffer spring 1104.

[0037] In a specific embodiment of the present invention, when the movable plate 12 contacts the buffer cylinder 1102, it will exert a force on it, and then transmit the pressure to the damper 1103 and the buffer spring 1104. At this time, the damper 1103 and the buffer spring 1104 will absorb the pressure and support and limit the movable plate 12. When the force of the movable plate 12 disappears, the damper 1103 and the buffer spring 1104 will drive the buffer cylinder 1102 to return to its initial position under the reaction force.

[0038] Specifically, a plurality of second sealing rings 16 respectively adapted to the plurality of connecting mechanisms 6 are disposed on the surface of the water control valve 1 , and a groove adapted to the second sealing rings 16 is opened on the surface of the water control valve 1 .

[0039] In a specific embodiment of the present utility model, the second sealing ring 16 is provided to increase the connection effect between the water control valve 1 and a plurality of connecting pipes, thereby reducing the probability of liquid leakage when connected to the connecting pipes.

[0040] Working principle: When in use, firstly, the connecting block 601 can be fitted with other connecting pipes, and the fixing nut 603 can be turned on the surface of the fixing bolt 602 to tighten the connecting pipe. At this time, water will flow in through the first valve port 2 on the surface of the water control valve 1 and flow out through the second valve port 3. When the flow rate of the water flow is too large, the buoyancy of the water will make the float 9 move on the surface of the limit shaft 8, thereby increasing the flow rate of water. Then the float 9 will lift the moving plate 12, and the movement of the moving plate 12 will drive the first sealing plate 13 and the second sealing plate 15 to move. When the moving plate 12 contacts with the buffer cylinder 1102, it will exert a force on it, and then The pressure is transmitted to the damper 1103 and the buffer spring 1104. At this time, the damper 1103 and the buffer spring 1104 will absorb the pressure and support and limit the movable plate 12, and under the action of the buffer mechanism 11, the movable plate 12 will have a vibration reduction and limiting effect. At this time, the excess water flow can be discharged through the third valve port 4, so as to achieve the effect of drainage. When the water level drops, the buoyancy decreases, and the float 9 and the movable plate 12 will drop and return to their initial positions. At the same time, after the force of the movable plate 12 disappears, the damper 1103 and the buffer spring 1104 will drive the buffer cylinder 1102 to return to its initial position under the reaction force.

[0041] 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 above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
