The aerofluxuss by-path in chamber；Described spring is extension spring, and one end of spring is fixedly connected with the piston, the other end of spring and exocoel bottom
It is fixedly connected.Before cylinder valve is opened, because depression bar pushes, the upper-end contact of plunger end and exhaust passage, hole is propped up in now aerofluxuss
Below exhaust hole, the gas in gas bomb cannot be discharged, and when cylinder valve is opened, plunger carries piston under the influence of air pressure
Move up, now the gas in gas bomb is discharged from steam vent after throttle orifice, and now aerofluxuss Zhi Kongwei is in exhaust hole
Lower section, with gas bomb gas discharge, air pressure reduce, piston moves in the presence of extension spring gradually downward, works as aerofluxuss
Hole is moved to when connect with exhaust hole, and now from the discharge of aerofluxuss by-path, when whistle, whistle sends gas portion gas
Sound, thus warn the gas in user gas bomb will exhaust.
Preferably, being provided with the spacing back-up ring spacing for piston extreme position in described cylinder sleeve；Described depression bar interior
End is provided with anticreep bulge loop, and the outer end of depression bar is provided with pressure handle.Spacing back-up ring is spacing for piston extreme position, and anticreep bulge loop prevents from pressing
Bar is departed from cylinder sleeve, is easy to use next time.
Preferably, the left surface of described valve body is provided with gas-charging connection, the right flank of valve body is provided with pressure gauge, valve body its
Remaining one side is provided with the relief valve connecting with exhaust passage.Gas in gas bomb can be filled by gas-charging connection after being finished
Gas, relief valve is used for controlling the air pressure in gas bomb, and pressure gauge is used for indicating the air pressure in gas bomb.
Therefore, this utility model has using simple, convenient, can control air-flow uniformly, continued emissions, reduce wasted air
Beneficial effect.
