The model utility content:
The technical problems to be solved in the utility model is that a kind of high pressure oxygen gauge valve that can avoid pressure gauge to be in the defective mode under the residual gas high pressure for a long time is provided.
Technical solution of the present utility model is that a kind of high pressure oxygen gauge valve with following structure is provided.It comprises valve body, gland nut, valve hole part, pin, handle, suction port, pressure gauge connection, be characterized on same valve body, also being provided with a bleed valve, the spool front end is put in the axial hole of the bleed valve in valve body, axial hole communicates with pressure gauge connection, also is provided with the venting aperture on the valve body.
After adopting above structure, compared with prior art, the utlity model has following advantage:
Be provided with a gas charging valve, a bleed valve, during monitoring pipeline air pressure, open gas charging valve, after pressure gauge cuts out gas charging valve by check monitoring pipeline air pressure acquisition data, open bleed valve, the residual gas that charges into during detection in pressure meter valve is discharged by vent connection, thereby avoid pressure gauge to be in defective mode under the high pressure for a long time, reduce the infringement of pressure meter valve, prolonged the working life of pressure meter valve.
