Common fault diagnosis and treatment of gas solenoid valve

When the gas solenoid valve is used for a period of time or just starting up, there will be some failures, such as non operation of electricity, the burning of the coil, the tight closure of the valve core and so on. There are many reasons for the failure of the gas electromagnetic valve, such as installation error, power supply voltage, and mechanical failure of the electric magnetic valve itself. The specific causes of failure and corresponding solutions are as follows:
First, check whether the working conditions of the gas solenoid valves have changed or exceed the scope of the work of the gas solenoid valves themselves, mainly including
1, voltage: too high and too low voltage will cause gas solenoid valve to work unstable.
2, temperature: too high or too low temperature will cause gas solenoid valve to work normally.
3, media properties: including medium temperature, viscosity and so on.

Two, next check whether the gas solenoid valve power supply wiring connection bad contact problem, need to re wiring.

Three: check whether the installation of gas solenoid valve has problems, such as installation direction.

Four: check whether the physical structure of the gas solenoid valve changes, or the parts of the solenoid valve are damaged, such as the spot of the welding or the loosening of the parts.

Five: check whether the gas solenoid valve has been clogged, the solenoid valve needs to be dismantled and cleaned up, and after the completion of the cleaning, the filter can be equipped for the solenoid valve to prevent the debris from entering the valve again.

Six: check whether the coil of the gas solenoid valve is short circuited. If there is such a situation, please change the coil in time.

Seven: if the newly bought explosion-proof gas solenoid valve, it is possible to choose the wrong model. Please recheck the actual working environment and the scope of the work of the solenoid valve.

The reasons for the failure of the gas solenoid valve, the reasons for the failure of the working conditions of the solenoid valve and the actual conditions of the environment occupy a part (the problem of selection), the next is the problem of installation, and other reasons such as the normal damage to the parts after the long-term work are also common.
