What is the use of the air pump solenoid valve

It is mainly used to control the opening and closing of the pipe, which should be two-position and two-way.

Two-position, two-way solenoid valve

1. Solenoid valves are divided into two categories in principle:

1) Direct-acting solenoid valve:

Principle: When the power is turned on, the electromagnetic coil generates electromagnetic force to lift the closing member from the valve seat, and the valve opens;when the power is turned off, the electromagnetic force disappears and the spring Press the closing member against the valve seat to close the valve.

Features: It can work normally under vacuum, negative pressure and zero pressure, but the diameter generally does not exceed 25mm.

2) Step-by-step direct-acting solenoid valve:

Principle: It is a principle that combines direct action and pilot type. When there is no pressure difference between the inlet and outlet, after power is applied, the electromagnetic force directly Lift up the pilot small valve and main valve closing parts in sequence to open the valve. When the inlet and outlet reach the starting pressure difference, after power is turned on, the electromagnetic force pilots the small valve. The pressure in the lower chamber of the main valve increases and the pressure in the upper chamber decreases, thereby using the pressure difference to push the main valve upward;when the power is turned off, the pilot valve uses the spring Force or medium pressure pushes the closing member to move downward to close the valve.

Why is the air pump solenoid valve leaking

The air compressor has been in operation for a long time. Due to the excessive temperature, the air compressor inside Solenoid valve coil is burned out or the wire is broken, so the air pressure Air leakage may occur. If this is the problem, you can replace the solenoid valve with a new one.

Generally speaking, air compressor leakage is mostly related to the solenoid valve coil, but you need to check whether it is the one-way valve or the largest copper on the one-way valve. If the screw is leaking, if it is the one-way valve, you can remove the largest screw on the one-way valve, find the spring and silicone pad directly inside, gently stretch the spring, and then reinstall it according to the original parts position.

Disassemble the solenoid valve. There is a seal underneath, which can be replaced. If it doesn’t work, replace it with a new onesolenoid valve. Also, you may have installed the solenoid valve backwards, rotate it 90 degrees axially and then reinstall it.
