Application description of vacuum flapper valve in life

A vacuum valve is a component of a vacuum system that regulates the flow of gas, shuts off or turns on the line.

The vacuum flapper valve is powered by compressed air. The electromagnetic reversing valve changes the direction of the gas path and performs the opening and closing movement of the cylinder drive flapper valve. It is suitable for opening or blocking the airflow in a vacuum system of 1.3×10-3Pa~1.0×105Pa. .

The flapper valve has the advantages of simple structure, short opening and closing time, safety and reliability, durability, and automatic control of the same length. It is widely used in electronics, chemical, metallurgy, aviation, aerospace, data, biomedicine, atomic energy, and space exploration. Science and technology field.

The cylinder diameter and piston rod diameter planning of the vacuum pneumatic flapper valve are very important. When the flapper valve is opened and closed, if the cylinder and piston rod diameter planning is unreasonable, the valve may not be opened, and the opening and closing time is long.
