[0002] The airtightness detection in the production process of valve pipe fittings is an important link to ensure the quality of valve pipe fittings. Usually, the valve is in a semi-open state, and the two ends of the valve are sealed with a flange cover with a pipe joint. Test medium (such as clean nitrogen or air) is introduced into one end, and the other pipe joint is blocked. A spray gun or brush is used to evenly apply soapy water on the connection interfaces and sealing surfaces of the valve pipe fittings, and observe whether there are bubbles generated. The shape and quantity of the bubbles can help determine the specific location and degree of leakage.

[0003] At present, the staff needs to move frequently between different observation positions to ensure that the surface of the valve pipe fittings can be comprehensively inspected. This may require them to climb ladders, squat or bend down to observe the valve pipe fittings from different angles and heights. Such frequent movement not only increases the labor intensity of the staff, but also may cause them to be fatigued during the observation process, thus affecting the accuracy and efficiency of the observation. Therefore, the utility model proposes an airtightness detection mechanism for valve pipe fittings production. Content of the Utility Model

[0033] The specific solution of this scheme is as follows: By controlling the water pump 61 to drive the water spray orifice plate 62 to spray water on the valve pipe fitting between the two clamping disks 12, so that soapy water covers the surface of the valve pipe fitting. By starting the air cylinder 41, the air cylinder 41 drives the push plate 42 to slide outwards through the telescopic end.
