The working principle of an air pressure reducer is mainly based on physical principles, ensuring stable output pressure by adjusting and controlling gas pressure. The following is its detailed working mechanism:

The air first enters the filtering chamber for water, oil, and dust removal treatment.

Then, high-pressure gas enters the feedback chamber, where there is a ball valve and diaphragm assembly. The ball valve is pushed open by a given spring, and gas flows into the output pipeline through the ball valve. Gas enters the feedback chamber through a small hole, and at this point, the force exerted by the air pressure on the diaphragm reaches equilibrium with the given spring force.

If the output pressure changes due to use, above or below the set value, the force on the diaphragm will lose balance with the spring force. For example, if the output pressure is lower than the set value, the diaphragm will shift downwards, increasing the opening of the ball valve and increasing the air pressure; If the output pressure is higher than the set value, the diaphragm will shift upwards, reducing the opening of the ball valve and lowering the air pressure.

Through this method, the air pressure reducer can continuously adjust the output pressure to maintain the desired set value.

This working mechanism makes air pressure reducers crucial in various applications, especially in situations where precise control of gas pressure is required.
