Abstract

The invention discloses an air inflation sealing device of a rail train door and a control method thereof. The air inflation sealing device comprises an air inflation and exhaust control relay K1, a first time-delay relay J1, a second time-delay relay J2, a train door closing in-place switch S1, a pressure detection switch S2, an air inflation electromagnetic valve Y1, an air exhaust electromagnetic valve Y2, a pressure indicator light H2 and an air inflation sealing rubber strip. The air inflation sealing device which is built by the relay, the time-delay relays and the quick air inflation sealing rubber strip eliminates the influence of software, is high in reliability, low in cost, small in size and small in requirement for the mounting space of a train, provides good late reformation, guarantees the air-tight seal property of the rail train, improves the comfort level of passengers and has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of rail transit door control, in particular to an inflatable sealing device for a rail train door and a control method thereof. Background technique [0002] With the rapid development of rail transportation, the requirements for the sealing performance of the vehicle are getting higher and higher. The sealing performance of the vehicle body is one of the important indicators to measure the quality of the vehicle. It directly affects the ride comfort of the vehicle, NVH (noise, vibration and acoustic vibration roughness), corrosion resistance, air conditioning efficiency, and fuel economy. Whether the sealing performance of the vehicle is good or not, the most direct feeling of passengers is the impact on noise and air conditioning performance. Good sealing of the vehicle body can effectively reduce the noise during vehicle operation, improve the efficiency of air conditioning, and reduce energy loss. Due t...
