Flow control valve working principle and its principle Flow control valve is in a certain pressure difference, relying on the size of the throttle orifice to control the size of the throttle orifice to regulate the implementation of components (hydraulic cylinder or hydraulic motor) speed Valves. Mainly include throttle, governor valve, overflow throttle and shunt manifold and so on. The installation form is horizontal installation. Flow control valve features: Flow control valve, also known as 400X flow control valve, is a multi-function valve using high-precision pilot flow control. Suitable for the distribution pipe to control the flow and pressure of the pipeline, to maintain a predetermined flow rate, the flow will be limited to a predetermined value, and appropriate to reduce the upstream high pressure, even if the main valve upstream pressure changes, it will not affect Flow downstream of the main valve. Flow control valve selection: According to the pipe diameter selection. According to the maximum flow and valve flow range selection. Flow control valve works: Digital flow control valve its structure is composed of automatic valve spool, manual valve spool and the display part. Display part by the flow valve movement, sensor transmitter, electronic calculator display part. Its job is complicated. The measured water flow through the valve, the flow of water impact flow impeller impeller, impeller rotation and sensing senor, the sensor sends a signal proportional to the flow rate, the flow of electrical signals through the wire into the electronic calculator, through the calculator Calculation, microprocessor processing, the flow value is displayed. Manual spool is used to adjust the flow, according to the display value to set the desired flow value. Automatic spool is used to maintain a constant flow, that is, when the pipe network pressure changes, the automatic spool will automatically open the fire under the pressure of small valve to maintain the set flow rate unchanged.
