The invention discloses a passenger car distribution valve suitable for electric pneumatic breaking. The passenger car distribution valve comprises a main valve body, a volume chamber exhaust passage communicating with a volume chamber is arranged in the main valve body, an electric pneumatic breaking control passage is arranged in the main valve body, and the volume chamber exhaust passage and a mounting surface of the main valve body are communicated with each other via the electric pneumatic breaking control passage, and a plug is arranged at an exhaust port of the volume chamber exhaust passage. The electric pneumatic breaking control passage making the volume chamber exhaust passage communicated with the mounting surface is arranged in the main valve body, so that the volume chamber compresses air to a magnetic valve to control air exhaust of the volume chamber so as to adapt to electric pneumatic breaking. The passenger car distribution valve suitable for the electric pneumatic breaking is ingenious in structure and obvious in effect, small in modification of the existing passenger car distribution valves and easy to produce.
Description
technical field [0001] The invention relates to a passenger car distributing valve suitable for electropneumatic braking. Background technique [0002] At present, the 104-type air distribution valve used in my country's railway passenger cars adopts the volume chamber exhaust channel to exhaust air during air braking, and the existing valve body structure cannot be applied to the structure of the electropneumatic braking control method. Contents of the invention [0003] The object of the present invention is to provide a passenger car distributing valve applicable to electropneumatic braking in view of the above existing problems. [0004] The technical solution of the present invention is realized in the following way: a passenger car distributing valve includes a main valve body, and a volume chamber exhaust passage communicated with the volume chamber is arranged in the main valve body, and it is characterized in that: in the main valve body An electropneumatic brake...
