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 controllable-rate formula gas circuit structure, source of the gas 1 via one-way valve 2 simultaneously with one end of gas tank 3, throttle valve D4 and a of 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 is communicated with gas tank 7, the b of described two-position three way magnetic valve C8
3port and a
3port is communicated with exhaust port 10 with one end 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 schematic diagram rapidly.In described inflation/deflation controllable-rate formula gas circuit structure, when two-position three way magnetic valve A5 power-off, a
1port conducting, b
1port ends, if now two-position three way magnetic valve B6 powers on, i.e. and b
2port conducting, a
