Remote Control Float Ball Valve F745X-10Q/16Q

The JD745X multifunctional water pump control valve consists of a main valve, a regulating valve, and a connecting system. The valve body adopts a DC type valve body, and the main valve control room is a dual control room structure of diaphragm or piston type. The control room is added to the general hydraulic control valve, which adds control function to the main valve. It realizes multi-functional control of the water pump outlet, such as slow opening, full opening, slow closing, and cut-off, and realizes multi-functional control of the water pump outlet with one valve and one adjustment. This valve is installed at the outlet of the water pump and sequentially achieves functions such as slow opening, full opening, quick closing, and slow closing.

The takeover system of the JD745X multifunctional water pump control valve adopts a regulating valve control. By setting the opening degree of the regulating valve, it is convenient to achieve the required control parameters, such as the opening speed and slow closing speed of the main valve.

The JD745X multifunctional water pump control valve is used on the outlet pipeline of water pumps in high-rise building water supply systems and other water supply systems, to prevent and reduce water hammer and water hammer in the pipeline when the water pump is opened and closed, prevent water back flow, protect the water pump, and maintain pipeline safety.

Operational principle:
After the water pump starts, the water pressure acts on the bottom of the main valve disc and the lower chamber of the control room, causing the main valve to open. The water in the upper chamber of the control room is slowly discharged to the outlet through regulating valve B, and the main valve slowly opens. Setting the opening degree of the regulating valve can obtain the appropriate opening speed of the main valve. After the water pump stops working, the water pressure at the inlet rapidly decreases. Under the action of self weight and spring pressure, most of the openings are quickly closed to prevent water back flow. The remaining openings are slowly closed by the combined action of the water pressure in the upper and lower chambers of the control room. The closing speed slows down to form a slow impulse, preventing a sharp increase in pressure.

Setting the opening and opening ratio of regulating valves A and B can obtain the appropriate valve opening and closing speed.

Product features

1. The prevention of water hammer is effective by integrating technologies such as slow opening, check and quick closing, and slow closing to eliminate water hammer. This prevents damage to the water supply pipeline and pump caused by pump failure and back flow during pump shutdown, as well as water hammer.
2. Easy to operate, there is no need to equip the valve with an additional electrical control system. The valve automatically and sequentially completes control functions with the opening and stopping of the water pump. By setting the opening of the regulating valve, appropriate control parameters can be obtained.
3. The valve body adopts a full channel, direct current, and streamlined design. Low hydraulic loss and good energy-saving effect.
