Description

Fresh air pressure wave protection valve for train

Technical Field

The utility model relates to a protection valve technical field specifically is a train new trend pressure ripples protection valve.

Background

The pressure change value of the running train is in direct proportion to the square of the train speed, the higher the train speed is, the larger the pressure change value is, and the pressure change rate of the high-speed train can reach thousands of Pa in 1 second. Although the train body, door and window have good air pressure tightness, the rapid change of the external air pressure can be transmitted into the train through the ventilation equipment, the pressure in the ears of the passengers and the external air pressure can not reach balance due to the air pressure change in a short time, and the uncomfortable feeling of auditory organs can be caused by the pressure difference between the inside and the outside of the eardrum. Therefore, when the vehicle speed is higher than 160KM/h, a pressure wave protection system is needed to control the fluctuation of the pressure in the vehicle, and the influence of the pressure wave is reduced to ensure the comfort of passengers. The pressure wave protection valve can be controlled by the pressure wave controller, and is closed when the pressure difference between the inside and the outside of the train meets the triggering condition, so that the air flow inside and outside the train is isolated, and the pressure fluctuation of the air inside the train is restrained.

In the prior art, pneumatic or electric pressure wave protection valve devices are generally used. The air source for the operation of the pneumatic pressure wave protection valve device is from the braking system of the train, and once the braking system is caused to be in failure, a great potential safety hazard is brought. And the pneumatic type pressure wave protection valve device has the advantages of high cylinder cost, large manufacturing difficulty, complex control system structure, easy occurrence of phenomena of air leakage and the like at a joint, large leakage detection difficulty and high maintenance cost. The electrodynamic type pressure wave protection valve device arranges the motor in the valve body lateral wall usually, because lateral wall mass distribution is uneven, the vibrations that the train operation produced very easily make the valve body lateral wall take place the skew, influence the life of protection valve. And in the closing process of the protection valve, the cover plate and the elastic sealing ring are easy to relatively slide, so that the elastic sealing ring is abraded.
