Testing device for pneumatic control valve production

The utility model belongs to the technical field of pneumatic control valves, and discloses a testing device for production of a pneumatic control valve. The testing device for pneumatic control valve production comprises a machining table, a water tank is fixedly installed on the right side of the machining table, a valve body is arranged on the upper surface of the water tank, a gas detection assembly is arranged on the machining table, and a flow velocity detection assembly is arranged on the water tank. According to the testing device for the production of the pneumatic control valve, an air pump in the air detection assembly is started to transmit air upwards through an air valve, the air bag is inflated after the air enters the air bag, and the air valve is opened and air is fed into the execution structure after the air in the air bag reaches a required pressure value; an operator can observe whether the gas can enable the elements in the execution structure to operate normally or not, and can also obs
