Abstract
A buffer valve is installed on a pneumatic diaphragm valve. An inner flow channel of the buffer valve includes an inner micro gas hole, an inner chamber, an outer gas hole, and a floating ball. The buffer valve has functions with a high-filling action, a shielding action, a releasing action, a shielding time Δt, and an adjusting mechanism. When inflatable, the floating ball will not block the inner micro hole to be quickly filled with high-pressure gas. when gas discharge, the floating ball will move to the outer gas hole with the gas flow and produce the shielding action to reduce the discharge rate to reduce the vibration and slow down the approach speed of the diaphragm to reduce the impact against the valve seat. When the pressure of the gas decreases, the floating ball is separated from the outer gas hole by the releasing action to accelerate the discharge.
