Knowledge of pneumatic pneumatic valve performance testing

one specification batch manufacturing pneumatic pneumatic valve, shall be authoritative institutions entrusted to test the performance of the following: (1) pneumatic valve open-close torque under working pressure conditions; (2) under the working pressure condition, can guarantee the pneumatic valve closed tight continuous opening and closing times; (3) pneumatic flow resistance coefficient of valve in the pipeline condition detection. Pneumatic valves should undertake the following inspection before they go out: (1) pneumatic valve in open conditions, the pneumatic valve body shall be double pneumatic valve working pressure value internal pressure test; (2) pneumatic valve closed condition, two side respectively. Times the working pressure pneumatic valve value, no leakage; But the metal seal butterfly pneumatic valve, the leakage value is not greater than the relevant requirements. Pneumatic pneumatic valve internal and external anti-corrosion: pneumatic valve body ( Including variable speed drive cabinet inside and outside, should first deoxidization blasting derusting, strive for electrostatic spraying powder, non-toxic epoxy resin in thickness. Mm and above. Oversize pneumatic valve electrostatic spraying non-toxic epoxy resin are in trouble, should also be similar non-toxic epoxy paint brush, spraying. Pneumatic valve body and internal pneumatic valve plate comprehensive anticorrosive parts requirements, on the one hand, soaking in the water will not rust, do not produce electrochemical corrosion between two metals; Two aspects of smooth surface reduce water resistance. Pneumatic valve body of anticorrosive epoxy resin or paint the sanitary requirements, should have the corresponding authorities inspection report. The physical properties of chemical also should comply with the relevant requirements.
