It extends to outside vacuum tank 5, one end that mandril 54 extends to vacuum tank 5 is fixedly connected with the turntable 542 for facilitating mandril 54 to rotate.Rotation
Turntable 542 is to drive mandril 54 to move in the vertical direction, when mandril 54 moves up, push plate 541 is pushed to make its promotion
Spring 53 so that piston 51 be made to need bigger power to the second cavity 57 is mobile, and then has been turned up vacuum tank 5 and has stablized air pressure；When
When mandril 54 moves down, push plate 541 is pulled to move down, so that piston 51 is made to need power smaller to the movement of the second cavity 57,
Stablize air pressure to turn down vacuum tank 5；The height that vacuum tank 5 stablizes air pressure is adjusted using turntable 542 and mandril 54, makes center
Air supply system is more convenient to use.
Specific working mode: centrifugal compressor 1 is delivered into after compressing air in main steam line 2, compressed air
It is delivered into gas manifold 3 and air accumulator 6 by main steam line 2.When terminal uses compressed air with gas point 4, gas supply
Main 2 compressed air of steam line is conveyed to terminal gas point 4 by branch pipe 3, and then air accumulator 6 is main steam line 2 gas supply, uses gas
The supply gas pressure in centrifugal compressor 1 is slowed down when measuring larger in short time.
When terminal gas point 4 is needed using lesser air pressure, relief tube 33 is controlled using regulating valve 331 and is lost heart flow,
Then the pressure of the gas supply of terminal gas point 4 is viewed as by pressure gauge 32, so that controlling gas manifold 3 is that terminal gas point 4 mentions
For the pressure of compressed air.
When terminal with gas point 4 with after gas, when closing gas manifold 3 using switch valve 31, swiftly flowing air because
Switch valve 31 is closed and is stopped suddenly, so that the flow velocity of compressed air is generated mutation, and then in main steam line 2 and gas manifold 3
In air pressure will increase, it is mobile to the second cavity 57 that air pressure will push piston 51, to increase the volume of the first cavity 56, and
And it is connected to the first cavity 56 with exhaust outlet 55, make the compressed air in the first cavity 56 that vacuum tank 5 be discharged by exhaust outlet 55,
To reduce the air pressure in the first cavity 56, and then reduce impact of the air pressure acute variation to central support air system.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
