The invention discloses a distribution valve for a brake system of a high-speed train, which comprises a valve substrate, and the valve substrate is provided with a train pipe orifice, an auxiliary air cylinder opening, a brake cylinder opening and an air outlet; and switchable connection and disconnection can be respectively performed between the train pipe orifice and the auxiliary air cylinder opening, between the auxiliary air cylinder opening and brake cylinder opening, and between the brake cylinder opening and the air outlet. The distribution valve disclosed by the invention is mainly used in a brake system of a high-speed train, and the internal structure of the distribution valve and the brake system for trains are simplified, therefore, the distribution valve meets the requirements of high-speed trains.
Description
technical field [0001] The invention relates to braking technology, in particular to a distribution valve used in a high-speed train braking system. Background technique [0002] The brake system is an essential part of rail trains. The common brake system usually includes a brake cylinder and an air pressure source. The air pressure source provides high-pressure gas for the brake cylinder, and the brake cylinder provides braking force through the gas pressure. The wheels or propshafts are mechanically squeezed to apply the brakes. [0003] With the development of train technology, the requirements for train safety are getting higher and higher. Some trains need to be equipped with a backup braking system. The backup braking system is mainly used in the return and rescue of trains. When the train needs to be returned and rescued, the rescue locomotive is connected to the rescued train, and the rescued train is pulled by the rescue locomotive, so that the rescue locomotive a...
