The multi-function water pump control valve is an intelligent valve installed at the pump outlet of the large-diameter water supply network system to prevent the water from flowing back and water hammer.
The flow control valve is a valve that adjusts the flow rate of the throttle port by changing the flow resistance of the throttle port under a certain pressure difference, thereby adjusting the movement speed of the actuator (hydraulic cylinder or hydraulic motor).
The result of the hydraulic control valve is still left and right fluid. In general, the orientation of the proportional valve will change according to the ball valve stem (the trapezoidal thread above) through the vertical plane of the elliptical brake in the direction of fluid passage. It is one of the valves.
There are many types of check valves, let’s introduce them below.
The report of the 18th National Congress of the Communist Party of China pointed out that technological innovation is a strategic support for improving social productivity and overall national strength, and must be placed at the core of the overall development of the country.
Compared with the globe valve, the gate valve has the main advantage that the fluid flow resistance is small.
