Description

Technical Field

[0001] The utility model relates to a valve detection device, in particular to a pressure valve air tightness detection device, belonging to the technical field of valve detection equipment. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters of the conveyed medium. Based on their function, they can be categorized as shutoff valves, check valves, and regulating valves. Valves are control components in fluid conveying systems, performing functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion, and overflow and pressure relief.

[0003] Chinese patent application publication number CN215492280U discloses a valve air-tightness testing device. This device secures the valve to be tested by installing a fixing mechanism on a testing platform. During testing, soapy water is applied to the valve and the leak is observed. This device performs air-tightness testing on the valve, reducing the labor intensity of the tester and addressing the potential risk of valves being put into service due to poor air-tightness.

[0004] Although the scheme of the above patent can detect the air tightness of the valve, the detection device in the above patent is not convenient for adjusting the detection device according to the different sizes of the valve. The detection valve is positioned by an inverted L-shaped clamping piece. When a valve of a different model is replaced, the height or size of the valve changes, which may easily cause the detection liquid to enter the interior of the valve during detection, affecting the valve detection effect. Therefore, a pressure valve air tightness detection device is proposed herein. Utility Model Content
