A device for detecting air tightness of valves in civil air defense projects

Abstract

This utility model discloses a valve airtightness testing device for civil defense engineering, specifically relating to the field of valve airtightness testing technology. It includes a base plate, a valve clamped between two side rings, and a second motor that rotates the rings and valve to align the valve's inlet and outlet with a suction port. A vacuum cleaner is then activated to remove impurities from the valve's inlet and outlet, preventing impurities from affecting the assessment of sealing performance and improving the accuracy of the test results. Furthermore, it removes impurities from inside the valve beforehand to prevent damage to the valve's internal structure. Some impurities may cause wear, scratches, or other damage to sealing parts or other critical components during testing, affecting the valve's normal use and lifespan. After testing, the first motor can be activated to rotate the first rotating plate and the clamping plate, which in turn rotates the valve body once. The vacuum cleaner then removes impurities from the outside of the valve body, achieving external cleaning.

Description

Technical Field

[0001] The utility model relates to the technical field of valve air tightness detection, in particular to an air tightness detection device for valves in civil air defense projects. Background Art

[0002] Civil air defense valves are pipe accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems and have functions such as shut-off, regulation, diversion, backflow prevention, pressure stabilization, diversion, or overflow pressure relief.

[0003] A Chinese patent with publication number CN219189954U discloses an air tightness detection device for valves in civil air defense projects. Through the provided rotating shaft, when the rotating shaft is rotated, the rotating shaft drives two groups of first gears through the second gear to make the two groups of screw rods rotate in opposite directions, thereby driving the two groups of fixed components to move towards or away from each other to achieve the effect of fixing or unlocking. At the same time, the structure is simple, easy to produce, and easy to operate.

[0004] However, the detection device in the above scheme fails to clean the impurities at the inlet and outlet of the valve in advance in time. The impurities may be near the sealing part during the detection process, interfering with the accurate judgment of the sealing effect and causing deviations in the detection results. Moreover, these impurities may move during the detection process and even embed into the sealing part or other key structures, thereby causing wear, scratches and other damages to the inside of the valve, affecting the performance and service life of the valve over time.
