Abstract

The invention discloses a railway vehicle air brake isolation device and an emergency brake interlocking control circuit, relates to the technical field of rail transit, and solves the problems that an existing isolation device needs to be manually operated, and common brake and emergency brake of a vehicle are lost at the same time after manual isolation air brake is carried out, the emergency braking has no other vehicle compensation function and the shortest braking distance cannot be guaranteed. Compressed air at a braking air cylinder is supplied to a remote isolation electromagnetic valve and a piston valve at the same time, and the remote isolation electromagnetic valve controls the connection and disconnection of the piston valve. When a braking system breaks down, a train networkis adopted for remotely controlling the remote isolation electromagnetic valve, the compressed air flows into a control port A4 of the piston valve through the remote isolation electromagnetic valve,a port A3 of the piston valve is communicated with a port A2, and the compressed air at the port A2 of the piston valve is exhausted; compressed air at a brake cylinder passes through a one-way valveand an electrified contact cutout cock and finally, the compressed air is exhausted through the A3 port of the piston valve, and the air brake is relieved.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to an isolating device for a rail vehicle that needs to be isolated and air braked when a braking system fails. Background technique [0002] At present, when the braking system of a rail vehicle fails, it needs to be isolated. The isolation device is a manual isolation device that needs to be manually operated. This device is generally installed in the compartment where the brake control device is located, and the BC pressure outlet of the brake control device. place. [0003] The manual isolating device is installed in the corresponding compartment. When it needs to be operated, the driver and passengers need to pass through the passengers in the compartment from the driver's cab and then reach the designated position in the corresponding compartment for operation. As a result, both the normal braking and emergency braking of the car are lost at the same time; after t...
