Abstract

The invention discloses an air brake valve for a passenger train. The brake valve comprises an acting portion, an operating air cylinder charging valve, a counterbalance valve, a balance valve and a local reduction shutoff valve. The acting portion comprises an air supply valve, a stabilizing portion and a main piston assembly. Actions of the brake valve are controlled through pressure differences caused by train pipe pressure variation so as to realize functions of charging, braking, pressure retaining, relieving and the like; the pressure of a braking cylinder is controlled by the pressure of a volume chamber, and two-pressure indirect control of the air brake valve of the passenger train is realized; by replacement of a traditional slide valve structure with a diaphragm plate and check valve plunger structure, structural simplicity and stability and reliability in operation are realized.

Description

technical field [0001] The invention mainly relates to an air brake valve for a railway passenger car. Background technique [0002] The railway passenger car air brake valve is the core component of the railway passenger car braking system, which controls the inflation, braking and release of the railway passenger car. [0003] The brake valves used in passenger cars are mainly 104 type passenger car air distribution valve (hereinafter referred to as 104 valve) and F8 type passenger car air distribution valve (hereinafter referred to as F8 valve); the main control mechanism of 104 valve is a two-pressure slide valve structure; The control mechanism is a three-pressure plunger structure, which has the switchability of stage relief and one-time relief. When the conversion cover of the distribution valve is placed in the stage relief position, it can be programmed for special use. When the conversion cover of the distribution valve is placed in the first relief When in place,...
