The piston type electric flow regulating and pressure regulating valve is a speed regulating and pressure regulating valve developed according to the hydrodynamic characteristics on the basis of drawing on the advanced experience of Germany and Japan, summarizing the domestic design, manufacturing and practical experience. It has been widely used in power station, water diversion, water supply and other fields. The improved flow control valve of this series is not only applicable to clean water, but also has good tolerance to natural river and lake water and light sewage. From the design structure and material selection, it solves the problem that the flow control valve is easy to scale, jam and drive device is too large for many years.

Working principle of the product

Electric flow regulating and pressure regulating valve is mainly used in water plant, power plant, water diversion project and other pipe network systems where the medium is water. It can regulate the medium flow, flow pattern and pipe network pressure. The most superior feature of this valve to the traditional flow control valve lies in its structural design and material selection, so that it is not afraid of sewage blocking the slide, scaling and jamming. The drive is significantly reduced. The valve can automatically adjust the preset parameter value of pipeline medium to keep it constant within a certain accuracy, and the accuracy range can also be adjusted. The valve has good cavitation resistance. The rib plate on the inner wall of the valve body has the function of a rectifier 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. The control system of the valve can adopt integrated electronic circuit, which is small in size, good in reliability, high in sensitivity and convenient in installation and debugging. The fully closed valve has zero leakage and can be used as a stop valve. It is unnecessary to set other stop valves. If the control degree and accuracy requirements are not very high, the control of the valve can be manual or ordinary electric. It can be installed horizontally or vertically.
