Embodiment Construction

[0020] The specific embodiment of the present invention will be further described in conjunction with the accompanying drawings.

[0021] Working principle of the present invention: the pipeline in the valve block 3 is mainly responsible for the connection between the air supply adjustment valve 1, the control valve 2, the shut-off plug valve 4 and the air cylinder. Integrating all pipelines on one valve block 3 reduces the connections between pipelines, and the volume is greatly reduced accordingly. And minimize the situation of air leakage. At the same time, in order to ensure more safety during operation and prevent possible backflow problems in the air supply adjustment valve 1, a ball core cut-off plug valve 4 is integrated on the valve block 3, so that the ball core cut-off plug can be closed during operation. The gate valve 4 further prevents the impact on the supervisor of the train, so as to achieve double insurance and ensure driving safety.

Abstract

The invention belongs to the funnel vehicle control part, and more particularly relates to a combination-typed manipulation valve used for a funnel vehicle; and the invention solves the problems of inconvenient disassembly and assembly, and the like which exist in the existing funnel vehicle wind control system. The combination-typed manipulation valve used for the funnel vehicle comprises a valve block; a wind supply adjusting valve, a manipulation valve, and a retaining plug door valve are installed at the external part of the valve block by a flange; and the internal part of the valve block is provided with a ventilation pipeline which is connected with the wind supply adjusting valve, the manipulation valve, and the cutout cock valve. The manipulation valve has the advantages that thereliability of a wind control system and the qualification rate for the manufactured parts are improved; the assembly process is simplified and the manufacturing efficiency of the vehicles is improved; the overhaul period of the vehicle is prolonged; the overhaul fees of the wind control system are reduced; and the requirements for the commodity are satisfied, and the quality is traceable.

Description

technical field [0001] The invention belongs to a control part of a hopper car, in particular to a combined control valve for a hopper car. Background technique [0002] The hopper car equipped with a transmission device and a wind control system is a special railway freight car, which automatically unloads ballast through a pneumatic pipeline device, thereby realizing mechanized construction and unloading. The air source of the pneumatic mechanical transmission system is directly taken from the main train, and the air storage cylinder of the pneumatic system is filled with air through the air supply adjustment valve. The wind control system usually includes control valves, air supply adjustment valves and other valve parts. The connection between the valve parts, the air cylinder and the air source is realized through the tapered thread of the pipeline. This connection method causes many adverse effects. Such as inconvenient disassembly and poor sealing, etc., which will a...
