The invention discloses a high-altitude overpressure balloon and an inflating and deflating device for an air bag of the high-altitude overpressure balloon. The high-altitude overpressure balloon comprises a centrifugal impeller, a diffuser and a driving motor, the diffuser comprises a diffuser casing, a diffuser mounting disc, a diffuser blade assembly and an adjusting mechanism; the diffuser casing is coaxially fixed above the diffuser mounting disc, and a gap is reserved between the bottom of the diffuser casing and the top of the diffuser mounting disc to form a diffuser flow channel; the centrifugal impeller is coaxially mounted on the side, facing the diffuser casing, of the diffuser mounting disc, and the driving motor is in driving connection with the centrifugal impeller; the diffuser blade assembly has a first working state and a second working state; the adjusting mechanism is used for enabling the diffuser blade assembly to be switched between the first working state and the second working state. The centrifugal impeller and the radial diffuser can be used for forming a unique fluid channel to achieve the three functions of pressurization inflation, natural deflation and closing, gas leakage channels are reduced, and the system integration degree is improved.
本发明公开了一种高空超压气球及其空气囊用充放气装置,包括:离心叶轮、扩压器和驱动电机;扩压器包括扩压器机匣、扩压器安装盘、扩压器叶片组件和调节机构;扩压器机匣同轴固定在扩压器安装盘上方,且扩压器机匣底部与扩压器安装盘的顶部留有间隙形成扩压器流道;离心叶轮同轴安装在扩压器安装盘朝向扩压器机匣的一侧,驱动电机与离心叶轮驱动连接;扩压器叶片组件扩压器叶片组件具有第一工作状态和第二工作状态;调节机构用于使扩压器叶片组件在第一工作状态和第二工作状态之间切换。本发明可利用离心叶轮和径向扩压器组成唯一的流体通道实现增压充气、自然放气和封闭三种功能,减少了气体泄漏通路,提高了系统集成度。
