Problems solved by technology

[0002] The air-conditioning pressure wave device structure of rail transit vehicles requires fast working speed and low noise. In order to meet the closing time requirements at the present stage, the time usually set for the whole process of closing the pressure wave device is relatively short, and the resulting problems are The noise becomes louder and the life span is reduced. It is difficult to achieve a balance between the two, and the comfort of the passengers in the car cannot be guaranteed stably.

Abstract

The invention relates to a rail transit vehicle air conditioner buffer pressure wave protection device which comprises a cylinder, a cylinder installation plate, a support column, a sealing plate, a sealing ring and an installation base plate. The support column is fixed on the installation base plate, the cylinder installation plate is fixed at the top end of the support column, the cylinder is fixed on the cylinder installation plate, the sealing plate is fixed on the end portion of a piston rod of the cylinder, the sealing ring is fixed on the upper surface of the installation base plate, the sealing ring is matched with the sealing plate, and a sealing plate lifting guide mechanism is arranged on the installation base plate and the sealing plate. The device can effectively increase the closing speed of a rail transit air conditioning system pressure wave device, solves the problem of large noise, and is simple in structure, low in manufacture difficulty, high in automation degree, high in response speed, low in noise and capable of being integrated on an air conditioning system to conduct centralized control.

Description

technical field [0001] The invention relates to a buffer pressure wave protection device, in particular to a rail transit vehicle air conditioner buffer pressure wave protection device, and the invention belongs to the technical field of rail transit vehicle air conditioning equipment. Background technique [0002] The air-conditioning pressure wave device structure of rail transit vehicles requires fast working speed and low noise. In order to meet the closing time requirements at the present stage, the time usually set for the whole process of closing the pressure wave device is relatively short, and the resulting problems are The noise becomes louder and the life span is reduced. It is difficult to achieve a balance between the two, and the comfort of the passengers in the car cannot be guaranteed stably. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, to provide a pressure wave device that can ma...
