Vertical-installation multifunctional air valve device

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.
