The invention relates to the technical field of rockets, in particular to an air pipe connector and an unlocking and separating mechanism thereof, which comprises a valve body, a piston, a valve core, a valve core driving spring and a positioning ball, in the locking state, under the action of the valve element driving spring, the valve element moves to the right limiting position, part of the surface of the lower portion of the positioning ball makes contact with the surface of the thick section of the valve element, the upper portion of the positioning ball stretches out of the positioning hole and stretches into the positioning groove of the separation sleeve of the fixing base, and the piston blocks the vent hole of the valve body. In the separated state, high-pressure gas is introduced into the driving cavity, the valve element moves to the left limit, part of the surface of the lower portion of the positioning ball makes contact with the surface of the thin section of the valve element, the upper portion of the positioning ball retracts into the positioning hole, the piston relieves blocking of the vent hole in the valve body, and the high-pressure gas enters the groove of the pull-out seat through the vent hole. And the fixed seat is pushed to be separated from the pull-out seat. The locking and separating mechanism of the air pipe connector and the air pipe connector can be more reliable.

    本申请涉及火箭技术领域,尤其涉及一种气管连接器及其解锁分离机构,包括:阀体、活塞、阀芯、阀芯驱动弹簧和定位珠;在锁紧状态下,在阀芯驱动弹簧的作用下,阀芯移动至右限位,定位珠的下部的部分表面与阀芯的粗段的表面接触,并且定位珠的上部伸出定位孔并伸入至固定座的分离套的定位槽中,活塞封堵阀体的通气孔;在分离状态下,向驱动腔内通入高压气体,阀芯移动至左限位,定位珠的下部的部分表面与阀芯的细段的表面接触,并且定位珠的上部缩回至定位孔内,活塞解除对阀体上的通气孔的封堵,高压气体通过通气孔进入拔出座的凹槽,以推动固定座与拔出座的分离。本申请可以使得气管连接器的锁紧分离机构以及气管连接器更加可靠。
