Description

Synchronous wheel controlled one-way non-return air valve device with vertically mounted adjustable non-return direction

Technical Field

The invention relates to an air valve device, in particular to a one-way check air valve device with an adjustable check direction, which is vertically installed on an adjustable ventilation type platform door in a subway.

Background

When a subway train runs, tunnel air can be driven to flow at a high speed due to limited tunnel space to generate piston air, and a large amount of heat can be brought to the tunnel due to air conditioner heat dissipation of a train carriage, friction heat dissipation of the train and a rail and heat dissipation when the train starts and brakes. If no measure or means is provided, piston wind carrying heat can enter and exit the subway station, so that the energy consumption of an air conditioner at the subway station in the air conditioning season is high, and the installed capacity of refrigeration equipment is large, therefore, in summer, an air valve on a platform door system of the subway station is required to be closed, and the purpose of isolating heat transfer between a tunnel and the platform is achieved.

In winter, the temperature in the tunnel is higher than that of a subway platform due to the heat generated by running and braking of the subway train, the temperature of the platform is higher than that of a station hall, the temperature of the station hall is higher than that of an outdoor, the heat in the piston air is a free heat source for heating in winter of the station, the temperature of the subway station is improved by fully utilizing the heat carried by the piston air in the tunnel, and the comfort level of passengers waiting for trains can be effectively improved. Therefore, in winter, the direction of air flow is required to be tunnel-platform-station-hall-outdoor, ensuring that cold air does not enter the tunnel.

And in transition season, air conditioning system in the subway station closes, when outdoor temperature is less than subway station temperature, can introduce outdoor air in the station, can effectively reduce subway station's mechanical ventilation energy consumption like this. At this time, the direction of air flow is outdoor-station hall-platform-tunnel, which is exactly opposite to winter.

However, the direction of the piston wind is bidirectional, when a train enters a station, the piston wind enters the station from the tunnel, and when the train leaves the station, the piston wind flows into the tunnel from the station.
