Cold-proof adjusting type combined air valve for subway ventilation in severe cold area and control method of cold-proof adjusting type combined air valve
PendingCN114837725ASolve the problem of fresh air supplyPrevent frostbiteEfficient regulation technologiesTunnel/mines ventillationAir volumeFresh air
The cold-proof adjusting type combined air valve for subway ventilation in the severe cold area is arranged in a piston air duct, an exhaust duct and a fresh air duct of a subway and comprises a plurality of valve body modules, two sets of actuators and a transmission mechanism, each valve body module comprises a valve body frame and two layers of single valve plates, each valve body frame is a rectangular frame, and the valve body frames are arranged in the valve body frames. The two layers of single valve plates form a double-layer valve body cavity in the middle of the valve body module, and a plurality of actuators and transmission mechanisms are arranged on the two sides of the double-layer multi-cavity combined valve body respectively. Therefore, the adjusting performance is high, adjusting under the small-air-volume working condition is closer to the linear adjusting characteristic, the occupied area is small, the appropriate fresh air volume is provided for green energy-saving products in winter, and the purposes of saving ventilation energy consumption and improving the comfort level in the station are achieved; the sealing effect is good due to the double-layer design and the multi-cavity design, and the electric heat preservation energy consumption of subway stations and intervals in winter in severe cold areas is reduced; in summer, entering of outdoor high-temperature air is reduced, and the comfort level in the station is improved.
