A valve body is connected with a front pipeline and a rear pipeline through flanges, a torsional spring used for rotating a valve plate is installed in an end cover, the end cover is fixedly installed at the top of the valve body, the valve plate is installed at the inner end of the valve body, and a ratchet fusing device provided with a heat knife is fixedly installed on the outer circumferential face of the valve body. One end of the fuse rope is connected with the valve plate, and the other end is fixed on the ratchet fusing device. The device is controlled through a circuit, opening and closing of the valve plate in the valve body are achieved, the requirement for discharging fuel oil in a pipeline is met, and therefore the effect of reducing the accident influence when an aircraft breaks down emergently is achieved. The device has the characteristics of simple structure, small occupied space, high automation level, long service life and the like. And the emergency oil discharge function of the aircraft can be well met.
本发明公开了一种飞行器紧急放油阀装置,阀体与前后管路通过法兰连接,用于旋转阀板的扭簧安装在端盖内部,端盖固定安装在阀体顶部,阀板安装在阀体内端部,配置有热刀的棘轮熔断装置固定安装在阀体的外圆周面上,熔绳一端连接阀板,另一端固定在棘轮熔断装置上。该装置通过电路控制,实现阀体内阀板的开启闭合实现管路中燃油的排放需求,从而实现飞行器发生紧急故障时的降低事故影响的作用。本发明具有结构简单、占用空间小、自动化水平高、使用寿命长等特点。可以很好地满足飞行器紧急排油功能。
