Valve air pressure detection device

Abstract

A valve air pressure detection device is disclosed and comprises a machine rack and a valve clamping mechanism arranged on the machine rack, the valve clamping mechanism comprises a mobile part and a fixed part, the mobile part can be arranged below the fixed part via a driving device in such a way that the mobile part can move up and down relative to the fixed part, a top face of the mobile part is provided with N detection cavities in which valves to be detected can be placed, the diameter of an opening of each detection cavity is smaller than the diameter of upper parts of the valves, each detection cavity is communicated with an air inlet pipe, a bottom face of the fixed part is provided with ventilation cavities corresponding to the detection cavities, the diameter of each ventilation cavity is smaller than the diameter of the upper parts of the valves, the ventilation cavities are communicated with lower parts of inner cavities of test tubes capable of holding liquid via air outlet pipes, top parts of the test tubes are provided with air outlet openings, air in the air inlet pipes is enabled to enter the ventilation cavities via the upper parts of the valves from the lower parts of the valves, the ventilation cavities are communicated with the inner cavities of the test tubes via the air outlet pipes, and N is a natural number greater than 1. The valve air pressure detection device is advantageous in that a plurality of valves can be detected at one time, and valve detection efficiency can be improved.

Description

technical field [0001] The invention relates to the field of valve detection equipment, in particular to a valve air pressure detection device. Background technique [0002] A Chinese utility model patent with the patent number CN201521036265.3 titled "A Valve Leak Detection Test Bench" discloses a valve leak detection test bench, which includes a workbench, a valve fixing seat, and a valve clamping device. A valve to be inspected is installed on the valve fixing seat and a valve opening device is provided. The valve clamping device includes two clamping parts arranged at both ends of the valve to be inspected and a drive device for clamping the valve to be inspected by the driving clamping part. One of the two clamping parts is connected to the air intake pipe, and the other clamping part is provided with an air pressure detection device. The opposite ends of the two clamping parts are provided with air vents, and the two air vents are respectively facing The two openings ...
