The invention discloses an emergency valve outside a vehicle. A first iron core coil is fixed to a valve cover, a second iron core coil is fixed to a valve seat, the first iron core coil and the second iron core coil are connected in parallel to form a coil circuit, a first switch and a second switch are connected into the coil circuit after being connected in series, a mechanical lock catch is installed on the valve seat, the valve cover is locked to the valve seat, and the first switch is arranged below the mechanical lock catch. After the second switch is closed, the mechanical lock catch is pressed to enable the first switch to be closed, after the first switch and the second switch are both closed, the coil circuit is powered on, and the first iron core coil and the second iron core coil are the same in polarity and generate repulsive force. The emergency valve is simple in structure, convenient to use and low in cost, the frozen emergency valve can be quickly and conveniently opened, and the problem that the low-temperature emergency valve is frozen and cannot be opened is solved. The mechanical lock catch integrates the locking action of the valve cover and the pressing action of the first switch, the whole structural design is compact and reasonable, the occupied space is small, and the using effect is good.
本发明公开了一种车外应急阀，第一铁芯线圈固定在阀盖上，第二铁芯线圈固定在阀座上，第一铁芯线圈与第二铁芯线圈并联形成线圈电路，第一开关与第二开关相互串联后接入线圈电路，机械锁扣安装在阀座上，并将阀盖锁合在阀座上，第一开关置于机械锁扣的下方，在第二开关闭合后，按压机械锁扣使得第一开关闭合，第一开关与第二开关均闭合后，线圈电路得电，第一铁芯线圈与第二铁芯线圈的极性相同并产生斥力。本发明结构简单，使用方便，成本较低，可以快速方便地打开冻住的应急阀，解决低温应急阀被冻住无法打开的问题。本发明中的机械锁扣集成阀盖的锁紧与第一开关的按压动作，整个结构设计紧凑合理，占据空间小，使用效果好。
