The piston flow regulating valve is a speed and pressure regulating type valve developed according to the characteristics of fluid mechanics. It has been widely used in power stations,water diversions, water supply, and other fields. The improved series of flow control valves are not only suitable for clear water, but also for natural river and lake water, and light sewage with good tolerance, from the design structure and material selection to solving the flow control valve for many years easy to scale, jamming, drive device is large problems.
Piston type regulating valve is a new type of regulating valve. It has a variety of control functions, such as water level control, pressure reduction, check-in, pressure relief, flow control, pipe break closing, etc. Its caliber ranges from 200 mm to 2400 mm, the pressure grade ranges from PN10 to PN100, and the pressure difference between inlet and outlet can reach 40kg / cm2. It not only fills the blank of large diameter control valve, but also fills the blank of high pressure and large differential pressure control valve. It is widely used in water supply, municipal pipe network, water plant and other fields.
Characteristics of electric flow regulating and pressure regulating valve
1. The advantage of the valve over the traditional flow control valve lies in its structure design and material selection, which makes it not afraid of sewage blocking the slide way, scaling phenomenon and jamming. The driving device is obviously reduced.
2. The valve can automatically adjust the preset pipe medium parameter value to keep it constant within a certain accuracy, and the accuracy range can also be adjusted.
3. The valve has good cavitation resistance. The rib plate on the inner wall of the valve body has the function of rectifying plate, which can disperse water flow and prevent cavitation. At the same time, it also reduces the noise of the valve and the vibration of the piston.
4. The control system of the valve can be integrated electronic circuit, small size, good reliability, high sensitivity, easy installation and debugging.
5. It can be used as a stop valve. There is no need to set other stop valves.
6. If the control degree and accuracy requirements are not very high, the control of the valve can be in the form of manual or ordinary electric.
