Provided are a vehicle and a valve emergency switching-off system thereof. The valve emergency switching-off system is applied to a pneumatic emergency switching-off valve of the vehicle and comprises an air storage device, a manual control valve and a door control valve. The air storage device is connected with the pneumatic emergency switching-off valve through an air supply loop. The manual control valve is arranged on the air supply loop between the pneumatic emergency switching-off valve and the air storage device. The door control valve is arranged at the position, between the manual control valve and the pneumatic emergency switching-off valve, in the air supply loop, and the door control valve is controlled by an operating box door. When the operating box door of the vehicle is closed, the door control valve is automatically switched off to cut off the air supply loop, and the pneumatic emergency switching-off valve is switched off. The door control valve does not need to be manually operated by operation personnel, but is controlled by opening and closing of the operating box door, and therefore control over the air supply loop of the pneumatic emergency switching-off valve is achieved, the pneumatic emergency switching-off valve is controlled, then the situation that the vehicle runs when the pneumatic emergency switching-off valve is switched on is avoided, and safe running is guaranteed.
Description
technical field [0001] The invention relates to vehicles, in particular to a valve emergency cut-off system for vehicles. Background technique [0002] The valve emergency shut-off system is often used on the pneumatic emergency shut-off valve of the tank truck. refer to figure 1 , Pneumatic emergency shut-off valve 2 has a pneumatic head. The pneumatic emergency shut-off valve 2 is connected to the tank body outlet of the tank transport vehicle. The pneumatic emergency shut-off valve 2 has two states of use: open and closed: when the pneumatic emergency shut-off valve 2 is in the open state, the medium in the tank can be output; When the pneumatic emergency shut-off valve 2 is closed, the medium in the tank cannot be output. [0003] read on figure 1 , the existing valve emergency shutdown system 3 includes: a gas storage device 31 and a manual control valve 32 . The gas storage device 31 is connected with the pneumatic head of the pneumatic emergency shut-off valve 2 ...
