Abstract

The embodiment of the invention provides an integrated air channel device. The device comprises a first cut-out cock, a second cut-out cock, a third cut-out cock and an air channel plate; the air channel plate is connected with a train pipe and a main air pipe; the three cut-out cocks are connected with the air channel plate; the first cut-out cock is used for controlling starting and stopping ofinflating the train pipe by the main air pipe; the second cut-out cock is used for controlling starting and stopping of inflating the main air pipe by the train pipe; the third cut-out cock is used for cooperation when the first cut-out cock and the second cut-out cock operate to achieve the situation that the main air pipe inflates the train pipe or the train pipe inflates the main air pipe. Theembodiment of the invention further provides an air channel control method of the integrated air channel device and a train. According to the device, all air channel elements are integrated on the airchannel plate, few pipe connectors are needed, potential leakage points are reduced, and the air impermeability is improved; by adopting a modularization installation mode, the operation time is shortened; the function of circulation of compressed air between the main air pipe and the train pipe is provided.

Description

Technical field [0001] The invention relates to rail transit technology, in particular to an integrated gas circuit device, a gas circuit control method thereof, and a train. Background technique [0002] The rail vehicle air brake system is mainly divided into two types according to the braking force control mode: the straight-through brake system and the automatic brake system. The brake cylinder compressed air of the straight-through brake system comes from the main air duct, and generates the corresponding braking force according to the braking command. The compressed air of the brake cylinder of the automatic braking system comes from the auxiliary air cylinder, and when the pressure of the train tube drops, the corresponding braking force is generated, and the compressed air of the auxiliary air cylinder comes from the train tube. [0003] Domestic rail transit vehicles such as subways, light rails, and EMUs generally use straight-through braking systems. When these vehicles...
