Pressure regulating valve diaphragm detection device and pressure regulating valve

Abstract

The utility model belongs to diaphragm detection technical field discloses a kind of pressure regulating valve diaphragm detection devices, for detecting the soundness of the diaphragm of pressure regulating valve, cavity is equipped in pressure regulating valve, diaphragm is located in cavity, this pressure regulating valve diaphragm detection device includes gas pressurization structure, gas transmission structure and pressure detection structure, gas pressurization structure is used to provide gas in cavity, pressure detection structure is used to detect and display the air pressure in pressure guide pipe. By gas pressurization structure, gas is pressed into the cavity of pressure regulating valve, gas flows into cavity through pressure guide pipe, when the value shown by pressure detection structure rises to certain value, stop pressing gas, observe the indication change condition of pressure detection structure, if the indication of pressure detection structure is stable, it is determined that diaphragm is sound, if the indication of pressure detection structure reduces, it is determined that diaphragm is damaged. Not only can the soundness of diaphragm be judged quickly and accurately, but also work efficiency can be improved significantly, and artificial cost and operation risk are reduced.
