Problems solved by technology

[0003] When the existing train is under emergency braking, the exhaust speed of the brake pipe is relatively slow, resulting in low wave velocity of the emergency braking of the train, and after the emergency braking of the emergency braking valve of the train, the pressure of the main train will drop to zero, which is not conducive to train's next relief

Abstract

The invention discloses an emergency braking acceleration exhaust valve, which is composed of an emergency valve and a pressure limiting valve. The air release valve seat and the emergency piston are composed. The brake pipe interface composed of the emergency valve body is directly connected with the train brake pipe. The pressure limiting valve consists of a pressure limiting valve body and a It consists of a pressure-limiting exhaust valve, and an exhaust port is arranged on the pressure-limiting valve body. The invention is directly connected with the brake pipe, and can sense the emergency braking of the train. The large aperture of the valve accelerates the exhaust of the brake pipe to increase the emergency braking wave speed of the train. When the air pressure of the train brake pipe drops to the pre-designed pressure , the valve stops air exhaust, which is conducive to the relief of the whole train after the emergency braking of the train.

Description

Technical field [0001] The present invention belongs to the technical field of railway vehicle is braked, and more particularly to an emergency braking exhaust valve acceleration. Background technique [0002] Railway vehicle emergency brake valve action of the brake pipe pressure is quickly discharged into the air atmosphere when the train emergency braking, the vehicle brake system to induce action, the vehicle is braked to achieve. [0003] An existing train emergency braking, exhaust brake pipe slower, causing the train emergency braking velocity is not high, and after the emergency brake valve of the emergency brake the train, the train competent pressure drop to zero, is not conducive to next train first remission. Inventive content [0004] Object of the present invention is: for the above-described problems in the realization there is provided a train emergency braking can be made to retain a certain pressure within the brake pipe emergency brake exhaust valve accelerati...
