The maintenance type solenoid valve means that the valve power switch action only needs to be energized for a moment, and the spool position does not need electricity to maintain. Its advantages depend on saving resources, especially in places where rechargeable batteries are used as switching power supplies, and do not need to consider leakage current, so the coil has a long life and has a high safety factor in high and low temperature, explosion-proof and other occasions. The common ones are mechanical retention and permanent magnet retention, and they are divided into double coils and single coils. The single coil magnetic retention structure is the simplest. It is to change the polarity of the DC power supply to change the two states of the matching gate valve power switch.

 

 

This kind of solenoid valve needs to add a switch for the external wiring of the solenoid coil independently installed, and it is very convenient to match with the smart instrument. The solenoid valve equipped with the IC card prepaid gas meter and water meter is the most important factor for the success or failure of the instrument panel. The self-sustaining technology is also an important factor for the success or failure of the solenoid valve. China's self-sustaining electromagnetic energy has gradually matured.
