The invention relates to the technical field of propeller beta valve adjustment, and provides a device for adjusting a propeller beta valve, which at least comprises a beta lever suitable for being hinged with the propeller beta valve; one end of the guide rod is hinged with one end of the beta lever; one end of the adjusting screw sleeve is connected with one end of the guide rod away from the beta lever; one end of the steel cable is suitable for being fixed to a casing of an engine, the other end of the steel cable is connected with the end, away from the guide rod, of the adjusting threaded sleeve, and the adjusting threaded sleeve can move in the length direction of the steel cable and drive the guide rod to synchronously move, so that the guide rod drives the beta lever to move, and the position of a propeller beta valve on the beta lever is adjusted. According to the device for adjusting the propeller beta valve, quick adjustment of the position of the propeller beta valve can be achieved, the requirement for the rotating speed of the positive propeller during slow operation of the propeller is met, the adjustment performability is higher, and more time and labor are saved.

    本发明涉及螺旋桨β活门调节技术领域,提供了一种调节螺旋桨β活门的装置,至少包括:β杠杆,β杠杆上适于铰接安装螺旋桨β活门;导杆,一端与β杠杆的一端铰接连接;调整螺套,一端与导杆远离β杠杆的一端相连;钢索,一端适于固定在发动机的机匣上,另一端与调整螺套远离导杆的一端相连,调整螺套能够沿钢索的长度方向运动并带动导杆同步运动,以使导杆驱动β杠杆运动,从而调整β杠杆上的螺旋桨β活门的位置。本发明提供的调节螺旋桨β活门的装置,能够实现螺旋桨β活门位置的快速调节,满足螺旋桨慢车正桨转速要求,调节的可执行性更高、更加省时省力。
