Description

Valve tightness test equipment Technical Field The utility model relates to the technical field of valve tightness test, in particular to valve tightness test equipment. Background The valve tightness test equipment is a special device for detecting the tightness of a valve under a specific pressure or vacuum condition, and has the core function of verifying whether the valve can effectively prevent medium leakage under a closed state. The equipment is widely applied to the fields of valve manufacturing, industrial installation, quality detection, maintenance and the like, and is a key procedure for guaranteeing the safety and reliability of the valve. The valve tightness test equipment quantitatively or qualitatively detects the tightness of the valve by simulating the actual working condition and judges whether the valve tightness test equipment accords with the design standard or the industry specification. In prior art, as the brass valve tightness test equipment that publication number CN221859837U discloses, it includes the workstation, and the stabilizer blade is installed to the bottom of workstation, and the bottom plate is installed to one side of mounting bracket, and the opposite side of mounting bracket runs through there is the threaded rod, and the rubber pad is all installed to one side of limiting plate and bottom plate. It constitutes threaded connection through installing the mounting bracket in the bottom of push pedal, threaded rod and mounting bracket, and the runner is rotatory just can drive the threaded rod and rotate, and the threaded rod is rotatory just can remove, and the threaded rod removes just can drive the limiting plate and remove, and the threaded rod runs through the holding ring, and the holding ring can prevent the condition that the skew appears in the threaded rod, and the limiting plate removes and just can press from both sides the valve between limiting plate and bottom plate with the bottom plate cooperation, carries out spacingly to the valve, and the rubber pad can seal the opening of valve, lets the valve inside seal, conveniently detects. The mounting bracket is installed through the bottom at the push pedal to current test equipment, and threaded rod and mounting bracket constitute threaded connection, carry out spacingly to the valve, and the rubber pad can seal the opening of valve, lets the valve inside seal, conveniently detects, but it is when the valve test, and the valve needs the water-through, can blow drying after the test, but it can't be to inside effectively drying, leads to inside remaining water to take place the circumstances of corruption easily.
