The reliability of the distributor valve is extremely important for the functioning of the air brake system. For this reason, reliability analysis of distributor valve based on the time to failure is shown in this paper. The distributor valve should react to changes in brake pipe pressure and provide the corresponding pressure in the brake ...
Fault detection and diagnosis of air brake system: A systematic …
2023年12月1日 · The air brake system takes compressed air to transfer energy, allowing smaller chambers to generate more significant braking force than the hydraulic brake. Air brake systems have evolved into various types to adapt to modern vehicle classes, such as pure air brakes and electro-pneumatic brakes [5], [6], [7], [8]. All of these brake systems ...
Distributor valve is the most important functional component of the air brake system and is also sometimes referred to as the heart of the air brake system. The distributor valve senses drop and rise in brake pipe pressure for brake application and release respectively. It is connected to the brake pipe through branch pipe.
416a Operation of KE Distributor Valve For effective functioning of the air brake system the KEGisl distributor valve has to operate effectively during - Charging stage - Application stage and - Release stage. (i) Charging Stage (se e figure 4.16) During this stage the compressed air flows from the driver's brake valve into the brake pipe which ...
Distributor Valve: The distributor valve KE1IPKSL is with pressure converter RLV-11d. The pressure converter restricts the max brake cylinder pressure to 3.0 kg/cm2. It has a quick release device. Also, if desired an EPZ-unit can be mounted to the valve body. Presently used in Tejas Coaches having speed potential of 200 kmph.-│13
Operation & Maintenance of Air Brake Systems for Railways
2015年7月17日 · Distributor Valve for application in the coach brake system used for initiating the brake application. These valves are supplied in aluminium version/cast iron
IRAB – 1 brake system has been designed by RDSO and fitted with New Generation ALCO locomotives. This is a complete air brake version, in which only compressor unit is used instead of Expressor for creating air pressure in the brake system …
The distributor valve connects the auxiliary reservoir to the brake cylinder and the brake cylinder piston is pushed outwards for application of brakes. The auxiliary reservoir is however continuously charged from feed pipe at 6 Kg/cm2. Brake pipe is fully exhausted and its pressure reduces to almost zero.
Brakes are released by recharging brake pipe to 5 Kg/cm2 pressure through the driver’s brake valve. The distributor valve isolates the brake cylinder from the auxiliary reservoirs. The brake cylinder pressure is vented to atmosphere through DV …
Present work deals with design and testing of a support bracket which is used for holding air brake distribution valve of railway freight. Five different brackets are
