How the flow control valve works
The digital display flow control valve is composed of an automatic valve core, a manual valve core and a display part. The display part consists of the flow valve movement, the sensor transmitter, and the electronic calculator display.
Its work is complicated. The measured water flows through the valve, and the water impinges on the impeller in the flow movement. The rotation of the impeller and the sensing of the sensor cause the sensor to send an electrical signal proportional to the flow rate. The flow signal is sent to the electronic calculator through the wire and goes through the calculator. After the calculation and microprocessor processing, the flow value is displayed.
The manual spool is used to adjust the flow rate, and the desired flow rate is set according to the displayed value. The automatic valve core is used to maintain the constant flow, that is, when the pipe network pressure changes, the automatic valve core will automatically open the fire and close the small valve port to maintain the set flow value.
Product Features of Flow Control Valves for Coal Machine Accessories
Flow control valve, also known as 400X flow control valve, is a multi-function valve that uses high precision pilot to control flow. Applicable to pipelines where the flow control system needs to control the flow and pressure, keep the predetermined flow rate constant, limit the excessive flow rate to a predetermined value, and appropriately reduce the upstream high pressure. Even if the pressure upstream of the main valve changes, it will not affect the flow rate. Flow downstream of the main valve.
Flow control valve selection: can be selected according to the pipeline diameter. According to the maximum flow and the valve flow range selection.
