Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the invention is described in further detail.
As shown in Figure 1, a kind of tri-state deflation rate controllable type gas circuit structure based on three-way magnetic valve, source of the gas 1 via one-way valve 2 respectively with a of gas tank C3 and two-position three way magnetic valve A4
1port is communicated with, the b of described two-position three way magnetic valve A4
1port and c
1port respectively with the c of two-position three way magnetic valve B6
2port is communicated with gas tank 5, a of described two-position three way magnetic valve B6
2port is communicated with throttle valve 8 Single port with gas tank D7 respectively, the another port of described throttle valve 8 and the b of two-position three way magnetic valve B6
2port is communicated with exhaust port 9 simultaneously.
Operation process is as follows
Fig. 2 is inflation schematic diagram.Described based in the tri-state deflation rate controllable type gas circuit structure of three-way magnetic valve, when two-position three way magnetic valve A4 powers on, a
1port conducting, b
1port ends, and ambient air imports gas tank 5 by source of the gas 1, one-way valve 2, two-position three way magnetic valve A4 successively, and airline pressure increases gradually, and a large amount of pressurized air stored by gas tank 5.The effect of one-way valve 2 and gas tank C3 prevents extraneous input air generation disturbance, causes gas circuit internal air pressure suddenly to decline.
Fig. 3 is slowly vented schematic diagram.Described based in the tri-state deflation rate controllable type gas circuit structure of three-way magnetic valve, when two-position three way magnetic valve A4 power-off, b
1port conducting, a
1port ends, and the pressurized air that gas tank is 5 li is by the b of two-position three way magnetic valve A4
1port conducting is to the c of two-position three way magnetic valve B6
2port.If now two-position three way magnetic valve B6 powers on, then its a
2port conducting, b
2port ends, and pressurized air is slowly discharged via gas tank D7, throttle valve 8, exhaust port 9; When gas circuit internal pressure drops to appointment threshold value, two-position three way magnetic valve B6 auto-breaking, b
2port conducting,
a2port ends, and gas circuit air pressure declines rapidly.
Fig. 4 is vented schematic diagram rapidly.Described based in the tri-state deflation rate controllable type gas circuit structure of three-way magnetic valve, when two-position three way magnetic valve A4 power-off, b
1port conducting, a
1port ends, and the pressurized air that gas tank is 5 li is by the b of two-position three way magnetic valve A4
1port conducting is to the c of two-position three way magnetic valve B6
2port.Now two-position three way magnetic valve B6 power-off, b
2port conducting, a
2port ends, and gas circuit gas is discharged rapidly.
