Abstract

A pneumatic control unit of an excrement collecting system for a bullet train is mounted in a position close to the excrement collecting system, and comprises a mounting board, wherein a stop valve, a main filter pressure reducing valve, an adjusting valve A, an electromagnetic valve A, a transfer box pressure detection switch, a pressure regulating valve B, a transfer box pipeline valve control electromagnetic valve, a pressure detection switch B, an electromagnetic valve B and a non-return valve are mounted on the mounting board, and the stop valve, the main filter pressure reducing valve, the electromagnetic valve A, the electromagnetic valve B, the pressure detection switch B, the pressure detection switch B, a transfer box pipeline valve control electromagnetic valve set and a vacuum-pumping electromagnetic valve are controlled by an excrement collecting controller; after passing through the stop valve and the main filter pressure reducing valve through an air inlet, compressed gas is divided into four branches for supplying to all gas using units. According to the invention, a control unit is integrally mounted on a mounting board, the structure is compact, the occupied area is small, and the repair and maintenance are convenient.

Description

technical field [0001] The invention relates to a pneumatic control device for a vacuum defecation collection system of a railway motor vehicle, belonging to the technical field of defecation collection systems. Background technique [0002] All or most of the actuators of the air circuit control device in the existing defecation collection system are under discrete and individual control states. This system is very messy and cannot be managed effectively, and once a fault occurs, it is difficult to correctly judge the cause of the fault as soon as possible. The maintenance personnel can only constantly replace different parts according to personal experience until the work is normal. In extreme cases, it may be possible to replace the last component before troubleshooting. As a result, not only the maintenance cost and maintenance time of the vehicle are greatly increased, but also the integrity rate of the feces collection system is reduced. The vehicle is easy to run with...
