Vertical-installation multifunctional air valve device

Abstract

The invention provides a vertical-installation multifunctional air valve device. The vertical-installation multifunctional air valve device comprises a valve body framework, a division board and self-drooping movable blades. The valve body framework is divided into a left channel and a right channel by the division board in the center of the valve body framework, a group of self-drooping movable blades which can be opened only in one direction are arranged inside each channel, and the opening direction of the self-drooping movable blades in one channel is opposite to the opening direction of the self-drooping movable blades in the other channel. The upper end and the lower end of the valve body framework are provided with two slideways respectively, a sliding valve plate is arranged in each slideway, the size of each sliding valve plate is the same as that of each channel opening, and through movement of the two sliding valve plates and opening of the self-drooping movable blades, the direction of airflow inside an air valve is controlled and changed or the airflow is stopped from flowing. According to the vertical-installation multifunctional air valve device, the problem that an electric air valve can not control the direction of piston wind in a subway station is solved, a shielded gate and an open / closed environmental control system of the subway station are organically combined, energy consumption of the environmental control system of the subway station in the operation process is effectively reduced, and energy is saved.

Description

technical field [0001] The invention relates to a damper device, in particular to a vertically installed multifunctional damper device on an inner screen door of a subway. Background technique [0002] When the subway train is running in the tunnel, the temperature in the tunnel will be high due to the heat dissipation of the train air conditioner, the friction heat dissipation between the train and the track, or the heat dissipation when the train starts to brake, and piston wind will be generated in the tunnel. In the absence of measures, the piston The wind will flow in and out of the subway station, causing the air-conditioning energy consumption and air-conditioning ventilation pipes of the subway station to be too large during the air-conditioning season. For this reason, screen door systems are currently installed in newly-built subway stations with station air-conditioning systems. [0003] When the season is over, because the temperature inside the tunnel > the c...

AI Technical Summary

Problems solved by technology

However, due to the two-way direction of the piston wind, sometimes it enters the station from the tunnel, and sometimes enters the tunnel from the station. At present, the method of setting an electric damper on the screen door cannot solve the problem of rational use of the piston wind in excessive seasons and winter.
