Train and train water supply system

Abstract

The invention relates to the technical field of train sewage disposal, especially to a train and a train water supply system. According to the train water supply system, a water tank is moved from thecar bottom to the car top and is arranged above a urinal and a washing facility, the water tank supplies water to the urinal and the washing facility through gravity, and the leakage risk and damagecaused by leakage are lowered; overall layout of the water tank, the urinal and the washing facility is compact, energy consumption is less, pipe arrangement is short, and recondition and maintenanceare convenient; a sewage box, the urinal, a transit box and the washing facility on the car are arranged in the car, the layout structure is compact, and pipe connection is simple; the sewage box is of a vertical structure and can be placed on a bottom frame of a car body, the side of the sewage box is mounted on the side wall of the car body, stable mounting is achieved, the vertical structure makes full use of the height space of a carriage, the horizontal space of the sewage box is reduced, and carriage utilization is improved; and relative to a lifting box body under the car, the sewage box structure arranged in the car is high in safety coefficient, less in energy consumption, convenient to maintain, and saving in space under the car, and the sewage box structure is suitable for carswith the small space under the car, such as double-deck car.

Description

technical field [0001] The invention relates to the technical field of train sewage discharge, in particular to trains and train water supply systems. Background technique [0002] At present, railway trains are common means of transportation for going out in people's daily life. The trains are usually equipped with water tanks to supply water to passengers on the trains. The train water supply system mainly provides various kinds of water, such as drinking water, kitchen water, bar water, electric boiler, washing water, toilet flushing water, and cleaning water, etc. The water tank is connected to the electric water boiler through the pipeline, and the electric water boiler boils water for drinking and washing; the water from the water tank passes through the branch pipe to the flushing valve, and when the toilet needs to be flushed, the button can be pressed at any time to flush. With the development of high-speed trains, in order to reduce the cross-section of the train ...

AI Technical Summary

Problems solved by technology

[0003] The water tanks of the existing EMUs and passenger cars are placed under the train, and there are many interfaces with the surrounding equipment. The pipeline layout is complicated, the distance is long, and the structure of the box is complex. The peripheral equipment needs to be removed during maintenance, which takes a long time
