Air tightness tester for pneumatic control flow valve

The utility model relates to the technical field of air tightness testing, in particular to an air tightness tester for a pneumatic control flow valve, which comprises a tester shell, and the left side of the top end of the tester shell is fixedly connected with an electric telescopic rod; according to the air tightness tester for the pneumatic control flow valve, through the arrangement of the motor, when the air tightness of the pneumatic control flow valve needs to be detected, after a user puts the pneumatic control flow valve needing to be detected into a clamp to be fixed, the motor can drive the workbench to rotate; the pneumatic control flow valve fixed in the clamp on one side above the workbench is rotated to the position below the tester body to be detected, and a user can place another pneumatic control flow valve needing to be detected into the clamp during detection. A user can directly start the motor to drive the workbench to rotate so that the pneumatic control flow valve which is fixed by an
