Pneumatic valve safety check of the three methods

security check of pneumatic valve is usually use a check online and offline check two kinds, one kind is a booster jump method, today small make up to you know about the simple, safe and pneumatic valve check three methods.

security pneumatic valve check online calibration method: by outside force will effect on the safety of pneumatic valve spring force downward to measure, in order to calculate the safety of the pneumatic valve opening pressure, this method is generally does not affect the production, the system pressure without changing, detection speed is faster and convenient, but the method cannot detect security pneumatic valve sealing performance;

security pneumatic valve check table offline calibration method: security pneumatic valve installed on the check, and then use the calibration medium make security pneumatic valve open, by observing the pressure gauge to confirm the opening pressure. This method cannot consider back pressure pneumatic valve safety and the safety of the high temperature or low temperature medium pneumatic valve check;

security pneumatic valve check station booster jump method: security pneumatic valve installed in the system, through the artificial booster system, pneumatic valve takeoff until the security, to observe safety pneumatic valve opening pressure, this calibration method for safety of pneumatic valve sealing surface damage is bigger, the operating risk bigger, is less used.
