The model utility content:
In order to solve the problem that single gas circuit air feed and existing two gas circuit air feed bring aborning, the utility model provides a kind of double-air-source air path automatic switching pressurizer.It can not only convert to by auxiliary source of the gas air feed, and can guarantee gas supply under constant pressure, thereby guarantee the proper functioning of pneumatic valve when gas source break down automatically.
The technological scheme that the utility model adopted is:
Described double-air-source air path automatic switching pressurizer, it is characterized in that: comprise main air pump, auxiliary air pump, main electromagnetic valve, pilot solenoid valve, pressure gauge, electric controller, ftercompction air bag, one-way valve, pneumatic valve, main airway and auxiliary port, main air pump interlinks by main airway, main electromagnetic valve and pneumatic valve; Auxiliary air pump interlinks by auxiliary port, pilot solenoid valve and pneumatic valve, main air pump, auxiliary air pump all link to each other with the ftercompction air bag by one-way valve, pressure gauge is installed on the main airway, main electromagnetic valve and pilot solenoid valve are controlled by electric controller, and pressure gauge links to each other with electric controller by pressure inductor.
Working principle of the present utility model:
Under normal circumstances, main air pump work, the pressed gas that main air pump produces is supplied with pneumatic valve by main airway through main electromagnetic valve, at this moment, pressure gauge shows normal pressure, and pressure inductor sends signal to electric controller, make auxiliary air pump and pilot solenoid valve be in closed condition, simultaneously, to the ftercompction airbag aeration, make the pressure in the ftercompction air bag reach predetermined value through one-way valve.When main air pump breaks down, main air pump quits work, pressure in the main airway can reduce fast at this moment, pressure gauge shows that force value also descends thereupon, send signal to electric controller immediately after the pressure inductor perception, close main air pump and main electromagnetic valve by electric controller, start auxiliary air pump and pilot solenoid valve simultaneously, by auxiliary air pump by auxiliary port and pilot solenoid valve to the pneumatic valve air feed, replace in the transfer process of main air pump air feed in auxiliary air pump, because life period is poor, the pressed gas of supplying with pneumatic valve can exist instantaneous pressure not reach the situation of setting value, and at this moment, the ftercompction air bag in time carries out ftercompction to pneumatic valve through one-way valve, make the gas pressure of supplying with pneumatic valve reach predetermined value, thereby guarantee the proper functioning of pneumatic valve.When auxiliary air pump normally behind the pneumatic valve air feed, auxiliary air pump by one-way valve to the ftercompction airbag aeration.
The utility model has adopted dual gas supply to the pneumatic valve air feed, and it can not only convert to by the auxiliary air pump air feed, and can guarantee gas supply under constant pressure when main air pump break down automatically, thereby guarantees the proper functioning of pneumatic valve.
