The application relates to an emergency relay valve comprising a shell, a driving opening, a control air inlet, a normal air inlet, an air storage air inlet, an air outlet, an air outlet channel, a driving piston and a valve, the driving piston is connected into the shell in a sliding mode, the interior of the shell is divided into a driving cavity and a control cavity, and the air outlet channel is connected with the air storage air inlet and the air outlet; a valve is arranged in the air outlet channel through an abutting piece so as to control opening and closing of the air outlet channel, and the driving opening communicates with the driving cavity; a return elastic piece is arranged between the driving piston and the shell, a control channel is formed in the shell and connected with the control air inlet and the normal air inlet, one end, away from the driving cavity, of the driving opening is communicated with the control channel. And a control assembly for controlling the emergency opening and the driving opening to be conducted when no air pressure is input into the normal air inlet is arranged in the control channel. After the connecting pipe of the normal gas inlet bursts, the control assembly controls gas in the gas storage gas inlet to enter the driving cavity and pushes the valve to be opened, and emergency braking is completed.

    本申请涉及一种紧急继动阀,包括壳体、驱动口、控制进气口、常进气口、储气进气口、出气口、出气通道、驱动活塞以及阀门,驱动活塞滑移连接在壳体内,将壳体内部分隔为驱动腔和控制腔,出气通道连接储气进气口与出气口,阀门通过抵紧件设于出气通道中以控制出气通道的通断,驱动口与驱动腔连通,驱动活塞与壳体间设有回位弹性件,壳体内设有控制通道,控制通道连接控制进气口和常进气口,驱动口远离驱动腔的一端连通控制通道,控制通道中设有在常进气口无气压输入时控制紧急口、驱动口导通的控制组件。本申请在常进气口的连接管爆裂以后通过控制组件控制储气进气口气体进入驱动腔并推动阀门打开,完成紧急制动。
