Usage, working principle and maintenance method of water inlet solenoid valve
Working principle of water inlet solenoid valve
The working principle of water inlet solenoid valve is to control the opening and closing of the valve by using the magnetic field of electromagnet. When the electromagnet is energized, it will generate a magnetic field, which will attract the iron core and close the valve. When the electromagnet is cut off, the magnetic field disappears, the iron core will return to its original position and the valve will open. In this way, the opening and closing of the valve can be controlled by controlling the switch of the electromagnet, so as to control the entry and exit of liquid or gas.
Maintenance method of water inlet solenoid valve
As a commonly used automatic control valve, the inlet solenoid valve needs regular maintenance to ensure its normal operation. Here are some maintenance methods of water inlet solenoid valve:
1. Clean the valve and valve body.
The valve and valve body of the water inlet solenoid valve are easily blocked by dirt and impurities, which affects the opening and closing of the valve. Therefore, valves and valve bodies must be cleaned regularly to ensure that they are unobstructed. The specific operation steps are as follows:
1) Turn off the power supply and disconnect the water inlet pipe.
2) Remove the valve and valve body and clean them with clean water and a soft brush.
3) Check whether the valve and valve body are damaged and replace them if necessary.
4) Reinstall the valve and valve body, connect the water inlet pipe, and power on for trial operation.
2. Check electromagnet and circuit.
The electromagnet and circuit of the water inlet solenoid valve also need to be checked regularly to ensure its normal operation. The specific operation steps are as follows:
1) Turn off the power supply and disconnect the water inlet pipe.
2) Remove the electromagnet, check whether it is damaged, and replace it if necessary.
3) Check whether the lines of the electromagnet are in good contact and reconnect them if necessary.
4) Reinstall the electromagnet, connect the water inlet pipe, and electrify it for trial operation.
3. Replace the seal
The seal of water inlet solenoid valve is easy to age and damage, which affects the sealing performance of the valve. Therefore, it is necessary to replace the seal regularly to ensure the sealing performance of the valve. The specific operation steps are as follows:
1) Turn off the power supply and disconnect the water inlet pipe.
2) Remove the valve and valve body, and take off the seal.
3) Check whether the seal is damaged or aging, and replace it if necessary.
4) Install a new seal, reassemble the valve and valve body, connect the water inlet pipe, and power on for trial operation.
