Working Principle of Flow Control Valve
Publisher：Botou Valve
Flow control valve is a kind of valve that controls the flow rate of throttle by changing the size of throttle resistance under a certain pressure difference, so as to regulate the movement speed of actuator (hydraulic cylinder or hydraulic motor). It mainly includes throttle valve, speed regulating valve, overflow throttle valve and diversion collector valve. Installation form is horizontal installation.
The working principle of flow control valve:
The structure of the digital flow control valve is composed of an automatic spool, a manual spool and a display. The display part is composed of flow valve core, sensor transmitter and electronic calculator display.
Its work is extremely complex. The measured water flow passes through the valve, impacts the impeller in the flow core, rotates the impeller and senses the transmitter. The sensor sends out a signal proportional to the flow. The flow signal is sent to the electronic calculator through the wire. After calculator calculation and microprocessor treatment, the flow value is displayed.
Manual spool is used to regulate the flow, according to the display value to set the required flow value. Automatic spool is used to maintain constant flow, that is, when the pressure of the pipe network changes, the automatic spool will automatically open a large fire and close a small valve to maintain the set flow value unchanged under the action of pressure.
