Is there any problem with the solenoid valve always being powered? Why is the solenoid valve always being powered
The solenoid valve is like a relay contact in two states: normally closed when power is off and normally open when power is on.
For example, when the solenoid valve of a drum washing machine is normally closed during a power outage, even if the faucet is opened, water will not flow in. When you start washing clothes, turn on the power and open the faucet. When the solenoid valve is in the closed state, water will automatically flow into the washing machine after the coil is energized and the valve is closed. When the amount of water is detected in the washing machine, the electric valve will be cut off and the water source will be turned off in the normally closed state. When the power is cut off, water will not flow out for no reason because the valve is in a normally closed state without power.
Solenoid valve, because the valve core is closed after power is supplied, that is, the normally closed function is reversed, and it will automatically close when the power is off. Close without releasing water. Depending on the user's demand for water release, the solenoid valve is installed, and it is normally closed (power outage and water outage). ) or normally open (with electricity and water)The solenoid valve uses the normally closed and normally open function and is used in automated drainage equipment , such as your common automatic solenoid valve to flush the toilet.
