Principle of action of normally closed two-position three-way solenoid valve.
The coil is energized and the gas circuit is connected. Once the coil is de-energized, the gas circuit will be disconnected, which is equivalent to "ignition". Principle of action of normally open two-position three-way single electric solenoid valve.
After the coil is energized, the air circuit is disconnected. Once the coil is powered off, the air circuit is connected. This is also called "jogging". The operating principle of the two-position five-way double electronically controlled solenoid valve;
When the positive action coil is energized, the positive action coil is turned on (the positive action coil has air in the vent), and the positive action coil will continue to be energized even if the positive action coil of the washing machine water inlet solenoid valve is de-energized. If the reaction coil is energized, the solar solenoid valve manufacturer's reaction gas circuit is connected (the reaction gas hole has gas), even when the reaction gas circuit is de-energized, the reaction gas circuit is still connected until the positive action coil is energized until. That is equivalent to "self-locking." According to this feature of the two-position five-way double electronically controlled solenoid valve, when designing an electromechanical control loop or writing a PLC program, the solenoid valve coil can be operated for 1 to 2 seconds to prevent damage to the coil.
