The embodiment of the invention provides an intermediate for a railway freight train control valve of an integrated dust filtering device, and relates to the technical field of vehicle braking. The middle body for the railway freight train control valve of the integrated dust filtering device comprises a middle body and the dust filtering device, the middle body is provided with a dust filtering cavity, a cavity and an air inlet cavity, the dust filtering cavity is communicated with the cavity and the air inlet cavity, the cavity is communicated with an emergency valve and a main valve, and an inlet of the air inlet cavity penetrates through the middle body. An inlet of the air inlet cavity is used for being externally connected with a train pipe. Wherein the dust filtering device is arranged in the dust filtering cavity, the dust filtering device is used for filtering gas entering the dust filtering cavity, and the filtered gas flows to the cavity and flows to the main valve and the emergency valve through the cavity. And therefore, the gas cleanliness in the control valve is guaranteed, the blocking phenomenon in the valve body is avoided, and normal use of the control valve is guaranteed.
本发明的实施例提供了一种集成滤尘装置的铁路货物列车控制阀用中间体,涉及车辆制动技术领域。该集成滤尘装置的铁路货物列车控制阀用中间体包括中间体以及滤尘装置,中间体设有滤尘腔、空腔以及进气腔,滤尘同时和空腔以及进气腔连通,空腔同时和紧急阀以及主阀连通,进气腔的入口贯穿中间体,且进气腔的入口用于外接列车管;其中,滤尘装置设置于滤尘腔内,滤尘装置用于对进入滤尘腔的气体进行过滤,过滤后的气体流向空腔,并经由空腔流向主阀以及紧急阀。从而保证控制阀内部的气体清洁度,避免阀体内部出现堵塞现象,保证了控制阀的正常使用。
