Abstract

An embodiment of the present application provides a rail vehicle water supply and drainage system, including: a clean water pipeline system, the clean water pipeline system includes a clean water tank and a water injection pipeline, and the water injection pipeline is connected to the clean water tank and set There is a water injection pressure switch; an air supply system communicates with the top of the clean water tank, the air supply system is provided with an air supply solenoid valve for the clean water tank, and the air supply solenoid valve for the clean water tank is electrically connected to the water injection pressure switch; The air supply solenoid valve of the clean water tank is controlled by the water injection pressure switch, and when the water injection pressure in the water injection pipeline reaches a preset value, the water injection pressure switch is powered off to close the air supply solenoid valve of the clean water tank , to prevent clean water from entering the air supply system; wherein, the water injection pipeline is used to inject clean water into the clean water tank, and the air supply system is used to provide high-pressure gas for water supply to the clean water tank. The embodiment of the present application solves the technical problem that the components of the traditional air pressure water supply method are easily damaged.

Description

technical field [0001] The present application relates to the technical field of rail vehicles, in particular to a rail vehicle water supply and drainage system. Background technique [0002] Most of the high-speed rail trains put the water tank under the car, which not only reduces the center of gravity of the train, but also helps to improve the stability of the rail train. The mode of water supply under the car is that the water tank is installed under the car, and the water supply mode of each water utensil on the car is supplied with water by power. The water supply under the car is usually divided into two ways: wind pressure water supply and electric pump water supply. [0003] figure 1 Schematic diagram of air pressure water supply for the water tank under the car. Such as figure 1 As shown, it includes a cold water pipe 11 , a floor 12 , a water injection pipe 13 and a main air pipe 14 , a three-way valve 21 , a five-way valve 22 , an air storage cylinder 23 and...
