Method of inspecting switching time with fluid control valve

摘要

A method of inspecting switching time with fluid control valve used for inspecting operating time to turn-on or turn-off a valve door of a fluid control valve is disclosed. The method comprises following steps: firstly provide an inspector with a counting unit, a timer, a first limited switch and a second limited switch. The counting unit electrically connects to the timer and a pneumatic module of fluid control valve, the first limited switch and second limited switch connect to the timer, and the first limited switch contacts the rod of the fluid control valve rod. Then, input basic data of corresponding fluid control valve, which comprises operating conditions of the fluid control valve. Next, activate the pneumatic module and start to time, and the axial shift generated by the rod of the fluid control valve triggers the second limited switch to stop timing. Lastly, record and display operating time.
