Abstract

The invention relates to an air drier in an air pressure brake system of a vehicle, in particular to a double-cylinder air drier with an oil filter drying cylinder and a water filter drying cylinder. In addition, the invention also relates to a compressed air brake system which uses the double-cylinder air drier and the vehicle which uses the compressed air brake system. The double-cylinder air drier comprises an air inlet (1), an air outlet (21), a valve body, a pressure regulating device, the oil filter drying cylinder, the water filter drying cylinder, an exhaust device and a backflow device, wherein the backflow device comprises a first valve (18), a cavity (N), a backflow hole (12), a throttle hole (10) and a first diaphragm (20); and the pressure regulating device comprises springs (13), a second valve (14), a second diaphragm (M) and a cavity (I). According to the compressed air brake system, the double-cylinder air drier is adopted. According to the vehicle, the compressed air brake system is adopted.

Description

technical field [0001] The invention relates to an air dryer used in a vehicle air pressure braking system, especially a double-tube air dryer with an oil filter drying cylinder and a water filter drying cylinder; The compressed air braking system of the cylinder air dryer and the vehicle using the compressed air braking system. Background technique [0002] In a vehicle air brake system, the gas required for braking is usually provided by an air compressor. Due to the continuous mechanical reciprocating motion of the compressor, the compressed gas provided by it has a high temperature and contains a large number of oil molecules and impurities caused by frictional motion. For this reason, in the traditional air brake system, a long copper pipe is usually provided at the outlet of the air compressor to cool the compressed gas, but because the compressed gas will produce condensed water in the process of cooling from high temperature to low temperature , and the mixing ...
