Description

A kind of valve impermeability detection system

Technical field

The utility model relates to the impermeability detection system of impermeability detection range, especially the multi-cavity body water swivel of technical grade or civilian middle-size and small-size valve of level or water swivel.

Background technology

In the manufacture process of valve products, impermeability is one of its most important quality index.Therefore, the air tightness detection equipment/system of this series products is the basic production equipment of relevant enterprise.

Present detection method mainly contains " range estimation (bubble) method ", " inflation simulation (pressure variation) method " and " special chemical gas tracer method " etc.Adopt the testing equipment of range estimation (bubble) method simple, cost is low, only need to inflate, soak or smear soap lye, observe bubble to confirm the impermeability of valve, also be the method that generally adopts; Adopt inflation simulation (pressure variations) method need adopt indicating instrument or the microcontroller etc. of pressure transducer, the pressure variation of specialty, belong to professional production equipment, cost is higher, for example proving installation; Adopt special chemical gas tracer method, use cost is higher, and may influence workers ' health, even cause environmental pollution, this method is abandoned gradually.

Contrast preceding two kinds of detection methods, be, not only can confirm measured piece (valve) impermeability by the great advantage of range estimation (bubble) method that extensively adopts, its leak source that can also confirm, but the artificial visually examine can bring erroneous judgement, causes the product yield that dispatches from the factory to descend.In addition, when adopting this method, between source of the gas and the measured piece link exist artificial uncertain turn round around, cause its sealing to descend easily, also can bring erroneous judgement; Adopt the professional pick-up unit of inflation simulation (pressure variations) method can avoid judging by accident, but be not sure of the leak source of the relatively poor product of impermeability, make this series products duplicate detection of manufacture process again, production efficiency is lower.

Summary of the invention
