The invention discloses a safety valve assembly of a propeller speed regulator. A lining is fixed in a lower shell assembly in a threaded mode. The cap is fixed to the upper end of an inner hole of the lining in a threaded mode, the spring shaft seat is arranged in the inner hole of the lining, the upper end of the spring shaft seat abuts against the inner hole of the cap, and the safety valve isclamped in a reducing inner hole of the lining. The pressure spring is sleeved and compressed between the spring shaft seat and the boss of the safety valve; a low-pressure oil cavity is further formed between the peripheral wall of the bushing and the lower shell assembly, and oil holes I and II which are both communicated with the low-pressure oil cavity are further formed in the peripheral wallof the bushing; the oil hole II is also communicated with a bushing inner hole in which the pressure spring is positioned; the distance between the spring shaft seat and the safety valve is larger than the distance between the lower end face of the safety valve and the lower end wall of the oil hole I. The oil pump outlet pressure of the speed regulator can be adjusted not larger than the maximumvalue so as to meet the variable pitch requirement of the propeller, mounting and dismounting are convenient, and the maximum limiting pressure is adjustable.

    本发明公开了一种螺旋桨调速器安全活门组件,衬套螺纹固定在下壳体组件内;帽盖螺纹固定在衬套内孔上端,弹簧轴座置于衬套内孔内,其上端顶靠在帽盖的内孔内,安全活门卡接在衬套变径内孔内;压力弹簧套并被压缩在弹簧轴座和安全活门的凸台之间;衬套周壁与下壳体组件之间还设置有低压油腔,周壁上还设置有都与低压油腔连通的油孔Ⅰ和Ⅱ;油孔Ⅱ还连通压力弹簧所在的衬套内孔;弹簧轴座和安全活门之间的间距大于安全活门的下端面与油孔Ⅰ下端壁之间的距离。本发明能够调整调速器油泵出口压力,使其不超过最大值,以满足螺旋桨的变距需求,且安装拆卸方便、最高限制压力可调。
