The invention provides an emergency release selector valve for an aircraft landing gear emergency release system. Comprising a valve main body piece, a valve sleeving piece arranged in a containing cavity in the valve main body piece, a movable oil way switching piece arranged in a containing cavity of the valve sleeving piece, a switching transmission piece used for driving the oil way switching piece to move, and a plurality of oil pipes connected with the valve main body piece. Wherein the switching transmission part is connected with an auxiliary linkage mechanism of the aircraft landing gear emergency release system through a connecting rod, and when an operator operates a handle mechanism of the aircraft landing gear emergency release system, a rear unlocking mechanism can be driven through a main linkage mechanism and the auxiliary linkage mechanism to unlock a lock of an aircraft rear landing gear. And meanwhile, the connecting rod drives the oil way switching piece to move, and oil way switching is achieved. According to the emergency release selection valve, an operator can manually switch oil ways, and therefore it can be guaranteed that under the emergency condition, the undercarriage can be driven to be released through hydraulic pressure.

    本发明提供一种用于飞机起落架应急放系统的应急放选择阀,包括阀主体件、设置在阀主体内的容纳腔内的阀套接件、设置在阀套接件的容纳腔内可移动的油路切换件、用于带动油路切换件移动的切换传动件、以及与阀主体件连接的多个油管,其中切换传动件通过连接杆与飞机起落架应急放系统的副连动机构连接,当操作者操作该飞机起落架应急放系统的手柄机构时,通过主连动机构、副连动机构可带动后方开锁机构对飞机后起落架的锁具进行开锁,同时通过连接杆带动油路切换件移动,实现油路切换。如上所述,本发明的应急放选择阀可供操作者手动进行油路切换,从而可保障在应急情况下也可通过液压驱动起落架放下。
