The invention provides an overpressure exhaust device which comprises a hand wheel, a lead screw stepping motor, a valve body, a sealing ring, a valve element, a position switch, a supporting plate, a circular ring nut and an electric connector. Wherein the valve body, the circular ring nut and the electric connector form a valve body assembly, and the valve element, the supporting plate, the lead screw stepping motor and the position switch form a valve element assembly. Through the threaded fit of the lead screw and the circular ring nut fixed on the valve body, the rotating motion of the lead screw is changed into the linear motion of the valve element assembly in the cavity of the valve body assembly, and the adjustment of the overpressure value in the sealed cabin is realized by adjusting the opening degree of the exhaust windows in the valve element assembly and the valve body assembly.
本发明提出一种超压排气装置,包括手轮、丝杆步进电机、阀体、密封圈、阀芯、位置开关、支撑板、圆环螺母和电连接器;其中,阀体、圆环螺母和电连接器形成阀体组件,阀芯、支撑板、丝杆步进电机和位置开关形成阀芯组件。通过丝杠与固定在阀体上的圆环螺母的螺纹配合,将丝杠的旋转运动变成阀芯组件在阀体组件腔体内部的直线运动,通过调节阀芯组件与阀体组件中排气窗口的开合度,实现对于密封舱内超压值的调节。
