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 inflation/deflation speed controllable type gas circuit structure, source of the gas 1 via one-way valve 2 respectively with gas tank 3, a of one end of throttle valve D4 and two-position three way magnetic valve A5 1port is communicated with, the b of described two-position three way magnetic valve A5 1port and c 1port respectively with the another port of described throttle valve D4 and the b of two-position three way magnetic valve B6 2port is communicated with, a of described two-position three way magnetic valve B6 2port and c 2port respectively with the c of two-position three way magnetic valve C8 3port and gas tank 7 are communicated with, the b of described two-position three way magnetic valve C8 3port and a 3port is communicated with one end and the exhaust port 10 of throttle valve E9 respectively, and the another port of described throttle valve E9 is communicated with exhaust port 10.
Operation process is as follows
Fig. 2 inflates rapidly schematic diagram.In described inflation/deflation speed controllable type gas circuit structure, in the time of two-position three way magnetic valve A5 power-off, a 1port conducting, b 1port cut-off, if now two-position three way magnetic valve B6 powers on, i.e. b 2port conducting, a 2port cut-off, ambient air imports gas tank 7 by source of the gas 1, one-way valve 2, two-position three way magnetic valve A5 and two-position three way magnetic valve B6 successively, and gas circuit pressure increases rapidly, and gas tank 7 is stored rapidly a large amount of pressurized air.The effect of one-way valve 2 and gas tank 3 is to prevent extraneous input air generation disturbance, causes gas circuit internal air pressure abrupt change.
