Background

With the rapid development of trains in recent years, high-speed trains are produced. The increase in the speed of the vehicle also places correspondingly higher demands on the comfort and safety of the vehicle. The pressure change value of the 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.

The pressure wave protection valve that uses at present generally adopts solid steel frame construction as bearing structure, and the weight of this kind of structure is great, not only can cause its self inertia great, produces great vibration easily to lead to structure damage such as seal pressure plate or base or support, for this we provide a lightweight waste discharge pressure wave protection valve and be used for solving above-mentioned problem.
