The multifunctional water pump control valve is composed of a main valve, a regulating valve and a pipe connection system. The main valve control room is a diaphragm or piston type double control room structure. The control room has one more control room than the general hydraulic control valve, and the main valve is added. Control function.
Features of multifunctional water pump control valve: 1. The valve body adopts a full-channel, direct-flow and streamlined design. The hydraulic loss is small and the energy saving effect is good. 2. Easy to operate, no need to add a power distribution control system for the valve, the valve will automatically complete the control function in sequence with the opening and stopping of the water pump. Appropriate control parameters can be obtained by setting the opening of the regulating valve. 3. The effect of preventing water hammer is good, integrating the technology of eliminating water hammer such as slow opening, non-return quick closing, slow closing, etc., to prevent the damage to the water supply pipeline and the water pump due to the failure of the pump, the backflow and the water hammer.
The working principle of the multifunctional water pump control valve 1. When the water pump is started, the water pressure acts on the bottom of the main valve disc and the lower cavity of the control room. This pressure makes the main valve open, and the water in the upper cavity of the control room slowly passes through the regulating valve B. Drain to the outlet end, and the main valve opens slowly. 2. Set the opening degree of the regulating valve to get a proper opening speed of the main valve. When the water pump stops working, the water pressure at the inlet drops rapidly, and most of the opening is quickly closed under the action of its own weight and spring pressure to prevent water backflow. The remaining opening is combined by the water pressure in the upper cavity of the control chamber and the water pressure in the lower cavity. Slowly closing down, the slowing down of the closing speed forms a buffer to prevent the pressure from increasing sharply.
The control valve of the multifunctional water pump is controlled by a regulating valve. By setting the opening of the regulating valve, the required control parameters can be easily realized. When we all operate and use the multifunctional water pump control valve, we should all operate according to the working principle of this control valve, and we should all understand these characteristics of our products
