We all know that the choice of solenoid valve is related to safety and convenience, first of all should follow the four major principles of safety, reliability, applicability and economy, but you have an understanding of the working principle of the solenoid valve? Below I will give you a detailed introduction to what is with manual function solenoid valve and solenoid valve manual button principle of operation.
What is a solenoid valve with manual function
Solenoid valve with manual function is a medium automation control device. It is widely used in air, water, hot water, gas, diesel and other pipeline control system; can be applied to shipbuilding, nuclear industry, petrochemical, fire, food, medical, cleaning equipment, electric power, boiler, chemical, light industry, military, aerospace, machinery, scientific research, drying equipment, water supply and drainage, pipeline media automation control and other fields.
Solenoid valve manual button working principle
1, ordinary manual function solenoid valve working principle
Normally open: valve to be automatically controlled, the manual handle must be in the open state; when the coil is de-energized, rotating the manual handle can control the valve switch.
Normally closed type: when the valve needs automatic control, the manual handle must be in the closed state; when the coil is de-energized, rotating the manual handle can control the valve switch.
2, alarm with manual solenoid valve working principle
A: the valve needs to be opened, spin down the shield (shield in the middle of the threaded holes, he screwed in the linkage lever as a handle to use), pull the handle, the valve opens.
B: When the valve needs to be closed, the coil will be energized for less than 30 seconds, and the valve will be closed rapidly.
Product features: the valve will not open automatically after closing in the power or power outage, need to manually pull open, keep open, energy saving, safety; stainless steel spool, stable performance; instantaneous energization, rapid cut-off; zero leakage.
Alarm solenoid valve incidental function is, when the valve is open, the signal public **** line and open the signal line connected; when the valve is closed, the signal public **** line and close the signal line connected. Manual function is, when the safety valve needs to be closed, screw down the manual shield, press the manual handle, the valve will be closed.
Alarm with manual solenoid valve can be used for gas, oil, corrosive fluids, etc., pressure in 0 ~ 1.6Mpa, temperature in -20 ~ +100 degrees, protection performance: waterproof, dustproof, explosion-proof, can be customized according to the customer's choice of working conditions. Viscosity should be less than 50C.St (greater than the need to customize), and the use of corrosive or explosive environments should be prioritized according to the safety requirements of the choice of hair erosion.
The above is about what is a solenoid valve with manual function and solenoid valve manual button principle of operation of the introduction, I hope to be able to recognize and buy solenoid valve with manual function to help. In addition, I also need to remind you, solenoid valves in the electric state of work can not be manually operated, so as to avoid unnecessary safety problems.
