As described above, switching valve module is made of multiple handover modules, each handover module has positive pressure gas port, negative pressure gas
Mouthful, control gas port and controllable sliding block control gas port and positive pressure gas port, negative pressure gas port are completed by the control to controllable sliding block
Switching；When control gas port is connected with positive pressure gas port, control gas port output is barotropic gas, and barotropic gas imports pressure bladder,
Pressure bladder expansion has the function that air locking or pushes the effect of device；When control gas port is connected with negative pressure gas port, control
There is negative pressure in gas port, need to suck gas, is inhaled into negative pressure gas cylinder with the gas in the pressure bladder of its unicom, pressure bladder is received
Contracting, has the function that depressurization device or retracts the effect of device；Switching valve module can carry out just multiple pressure bladders
Pressure/negative pressure switching control.
As described above, collection air bag is reserved with gas supplementing opening, thus the gas that positive and negative pressurized air source whole system is run all injects.
The advantageous effect of the invention is：The invention automatic continuous can provide positive and negative pressurized air source, and can be by positive and negative
Sealing or push-and-pull process are externally completed in the completion positive pressure/negative pressure switching that automatically controls of pressurized air source.
