The invention discloses an air brake valve of a passenger train. The air brake valve is composed of main valves, a middle body and an emergency valve, the middle body is an installation base, is a connecting part of the brake valve and a train body and is used for a train pipe, a working air cylinder, a brake cylinder and an auxiliary air cylinder to be communicated with corresponding air paths inthe main valves and the emergency valve respectively. The main valves comprise an acting part, an air supply valve, an auxiliary air cylinder inflation check valve, a working air cylinder inflation valve, a balance valve, a local reduction closing valve and a balance valve. In order to mainly solve the problems that an existing brake valve is not high in operation stability and cannot meet the maintenance requirement, a traditional sliding valve structure is omitted, and the plunger type structural design of a two-pressure control and indirect action mode is adopted, so the operation stability and reliability of the brake valve are guaranteed, and the maintenance kilometers required by railway vehicles are met.
本发明公开了一种铁路客车空气制动阀,由主阀、中间体以及紧急阀组成,所述中间体为安装座,是制动阀与车体的连接部分,并用于列车管、工作风缸、制动缸以及副风缸分别与主阀和紧急阀内各对应气路相连通,所述主阀包括作用部、供气阀、副风缸充气止回阀、工作风缸充气阀、平衡阀、局减关闭阀以及均衡阀。本发明主要针对现有制动阀运行稳定性不高,且无法满足检修要求的问题,通过取消传统的滑阀结构,采用二压力控制、间接作用方式的柱塞式结构设计,从而保证制动阀的运行稳定性和可靠性,并满足铁路车辆要求的检修公里数。
