What should I do if the water solenoid valve does not work?

The water solenoid valve is a solenoid valve product that is closely related to our life and is suitable for water, air, oil and other media. The use of any equipment will inevitably lead to some failures, the key is how to troubleshoot. Not working is one of the common faults of water solenoid valves. What should I do?
(1) The water is stuck with a solenoid valve. The clearance between the sliding valve sleeve of the solenoid valve and the valve core is very small (less than 0.008 mm), and it is generally a one-piece assembly. When mechanical impurities are introduced or the lubricating oil is too small, it is easy to get stuck. The treatment method can use a steel wire to break in from the small hole of the head to make it bounce back. The fundamental solution is to remove the water solenoid valve, take out the valve core and the valve core sleeve, and clean it with CCI4, so that the valve core can move flexibly in the valve sleeve. When disassembling, pay attention to the assembly sequence of each component and the external wiring position, so as to reassemble and wire correctly, and check whether the oil mist injection hole is blocked and the lubricating oil is sufficient.
(2) The water solenoid valve coil is burned out. The wiring of the solenoid valve can be removed and measured with a multimeter. If the circuit is open, the water solenoid valve coil is burned out.
The reason is that the coil is damp, causing poor insulation and magnetic leakage, causing the current in the coil to be too large and burning, so it is necessary to prevent rainwater from entering the solenoid valve. In addition, the spring is too hard, the reaction force is too large, the number of turns of the coil is too small, and the suction force is insufficient to cause the coil to burn.
(3) The solenoid valve of the water is loose or the wire head is detached, and the water solenoid valve is not allowed to be used, and the wire end can be fastened.
(4) Air leaks. Leakage can cause insufficient air pressure, making it difficult to open and close the forced valve due to damage to the gasket or wear of the spool to cause several cavity helium.
