Detailed Description
Referring to fig. 1 to 5, a micro-resistance large-flow multifunctional ball float valve includes: a valve cover 1, a valve core 2 and a valve body 3; the valve core 2 is arranged between the valve cover 1 and the valve body 3 and divides the float valve into an upper chamber and a lower chamber;
the valve element 2 includes, from top to bottom: the device comprises a lock nut 21, a diaphragm upper pressing plate 22, a diaphragm 23, a diaphragm lower pressing plate 24, a sealing piece 25, a sealing piece pressing plate 26 and a pilot valve rod 27;
the middle part of the pilot valve rod 27 is hollow, the bottom is provided with a filter screen cover 271, and the top sequentially passes through the sealing sheet pressing plate 26, the sealing sheet 25, the diaphragm lower pressing plate 24, the diaphragm 23 and the diaphragm upper pressing plate 22 from bottom to top and is fixedly connected with the lock nut 21; the diaphragm 23 is made of rubber.
The valve cover 1 is also provided with a valve opening adjusting device 4.
The remote control ball cock is also provided with an on-off signal debugging and overhauling valve 5 on a pipeline connected with the ball cock in the water tank.
When the valve is in an open state, water flow is divided into two paths, wherein most of water flows from the water inlet to the water outlet, the small part of water flows to the hydraulic control cavity through the pilot valve rod 27, then flows to the water tank (pool) through the on-off signal debugging maintenance valve 5, after the liquid level of the water tank (pool) is full, the float valve (a valve connected with the float ball and arranged in the water tank) is closed, the pressure of the hydraulic control cavity (the upper cavity) is increased, the main valve is closed, and water supply to the water tank (pool) is stopped; when the liquid level of the water tank (pool) is reduced, the hydraulic control chamber (upper chamber) is depressurized, the main valve is opened, and water is supplied to the water tank (pool) again.
The valve opening adjusting device 4 can adjust the opening size of the valve according to the on-site working condition, adjust the flow of liquid passing through the valve, and eliminate the pipeline resonance generated during the liquid circulation.
The hydraulic pilot control is adopted, the valve is tightly and reliably closed, the valve is smoothly opened, the firm rubber sealing ring is adopted for sealing, the hydraulic control principle is utilized, the closing force of the valve is in direct proportion to the water inlet pressure, and the sealing reliability is high. The overflow is big, and the valve body adopts full channel streamline design, and liquid resistance is little, and the flow is big. The structure is simple, the redundancy design is avoided, and the efficiency in the installation and debugging process is effectively improved. The main valve body adopts wax film precision casting, the processing procedures are few, and the production efficiency and the processing precision are effectively improved. The valve cover is integrally formed by one-step stamping, so that the machining procedures are few, and the production efficiency and the machining precision are effectively improved. Compared with the existing similar products, the product effectively reduces the processing procedures, shortens the production period, effectively reduces the production and processing costs and improves the reliability of the product in the use process.
The above examples and drawings are not intended to limit the form or form of the present utility model, and any suitable variations or modifications thereof by those skilled in the art should be construed as not departing from the scope of the present utility model.
