1port conducting, a
1port cut-off, ambient air imports a of two-position three way magnetic valve B6 successively by source of the gas 1, one-way valve 2, two-position three way magnetic valve A5
2port, if now two-position three way magnetic valve B6 powers on, its a
2port conducting, b
2port cut-off, gas enters rapidly gas tank 8 through two-position three way magnetic valve B6, and gas circuit pressure increases rapidly, and gas tank 8 is stored a large amount of pressurized air.The effect of one-way valve 2 and gas tank C3 is to prevent extraneous input air generation disturbance, causes gas circuit internal air pressure abrupt change.
Fig. 3 slowly inflates schematic diagram.In described a kind of tri-state inflation rate controllable type gas circuit structure, in the time that two-position three way magnetic valve A5 powers on, a
1port conducting, b
1port cut-off, ambient air imports a of two-position three way magnetic valve B6 successively by source of the gas 1, one-way valve 2, throttle valve 4, two-position three way magnetic valve A5
2port, if now two-position three way magnetic valve B6 powers on, its a
2port conducting, b
2port cut-off, gas slowly enters gas tank 8 through two-position three way magnetic valve B6, and gas circuit pressure increases gradually.
Fig. 4 is exhaust schematic diagram.In described a kind of tri-state inflation rate controllable type gas circuit structure, in the time of two-position three way magnetic valve B6 power-off, b
2port conducting, a
2port cut-off, the pressurized air that gas tank is 8 li is by the b of two-position three way magnetic valve B6
2port conducting is to exhaust port 7, and gas circuit gas is discharged rapidly.
