High Temperature Globe Valves
Introduction:
The high temperature globe valve is a valve that uses the pressure and temperature of the medium itself to open and close, and is suitable for high temperature and high pressure medium.
Working Principle:
When the flow value measured by the counterflow flowmeter exceeds the set value or reaches the flow rate, the solenoid coil switch is automatically turned on to cut off the power to the electromagnet and cut off the power supply to stop working (that is, shut down). Since the electromagnet cannot be reset after power failure, the valve will not continue to flow through the valve at this time, thus preventing the occurrence of malfunction (that is, the anti-malfunction function).
When the set value of the flow value measured by the counterflow flowmeter fails to meet the export volume requirement, the solenoid coil switch is automatically turned on to energize the electromagnet and resume work (that is, the opening indication). Since the electromagnet can be reset after power-on At this time, the valve will automatically open and continue to pass through the liquid, thereby preventing the occurrence of liquid leakage.
