Abstract
The invention provides a tri-state air channel structure with the controllable air inflation speed, and belongs to air storage pneumatic actuators. An air source is communicated with an air storage tank, one end of a throttling valve and the port b1 of a two-position three-way electromagnetic valve A through one-way valves, the port a1 and the port c1 of the two-position three-way electromagnetic valve A are communicated with the other end of the throttling valve and the port a2 of a two-position three-way electromagnetic valve B respectively, and the port b2 and the port c2 of the two-position three-way electromagnetic valve B are communicated with an exhaust hole and the air storage tank respectively. According to the tri-state air channel structure, air is used as medium, central air supply is achieved by means of compressibility of the air, machining and maintaining of a mechanical structure are greatly simplified, and intelligent control over the work speed can be achieved. The tri-state air channel structure has the advantages of being simple in structure, low in manufacturing cost, safe and reliable in work, long in service life, suitable for long-distance transmission and the like.

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 inflation rate controllable type gas circuit structure, source of the gas 1 via one-way valve 2 respectively with gas tank 3, the b of throttle valve 4 one end and two-position three way magnetic valve A5
1port is communicated with, a of described two-position three way magnetic valve A5
1port and c
1port respectively with a of described throttle valve 4 the other end and two-position three way magnetic valve B6
2port is communicated with, the b of described two-position three way magnetic valve B6
2port and c
2port is communicated with gas tank 8 with exhaust port 7 respectively.
Operation process is as follows
Fig. 2 inflates schematic diagram rapidly.In described a kind of tri-state inflation rate controllable type gas circuit structure, when two-position three way magnetic valve A5 power-off, b
1port conducting, a
1port ends, and ambient air is successively by a of source of the gas 1, one-way valve 2, two-position three way magnetic valve A5 importing 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 gas enters rapidly gas tank 8 through two-position three way magnetic valve B6, and airline pressure increases rapidly, and a large amount of pressurized air stored by gas tank 8.The effect of one-way valve 2 and gas tank C3 prevents 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, when two-position three way magnetic valve A5 powers on, a
1port conducting, b
1port ends, and ambient air is successively by a of source of the gas 1, one-way valve 2, throttle valve 4, two-position three way magnetic valve A5 importing 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 gas slowly enters gas tank 8 through two-position three way magnetic valve B6, and airline pressure increases gradually.
Fig. 4 is exhaust schematic diagram.In described a kind of tri-state inflation rate controllable type gas circuit structure, when two-position three way magnetic valve B6 power-off, b
2port conducting, a
2port ends, and 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.
