Technical Field
The invention relates to an air valve device, in particular to an air valve device which is vertically installed on a subway inner shielding door and can adjust the non-return direction.
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 subway train generates heat during running and braking to ensure that the temperature in the tunnel is higher than that of the subway platform, the temperature of the platform is higher than that of the station hall, the temperature of the station hall is higher than that of the outdoor, the heat in the piston wind is a free heat source for heating in winter at the station, the temperature of the subway station is improved by fully utilizing the heat carried by the piston wind in the tunnel, and the comfort level of passengers waiting for the subway station 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.
In the transition season, the air conditioning system in the subway station is closed, when the outdoor temperature is lower than the temperature of the subway station, outdoor air can be introduced into the station, so that the mechanical ventilation energy consumption of the subway station can be effectively reduced. 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.
Disclosure of Invention
In order to solve the problems in the prior art, the invention provides a one-way non-return air valve device controlled by double angle irons, which overcomes the problem that the adjustable ventilation type platform door of an electric air valve on a subway shield door in the prior art cannot effectively solve the problem of one-way utilization of piston air in transition seasons and winter.
The technical scheme adopted by the invention is as follows: the utility model provides a one-way non return blast gate device of two angle irons control, includes the valve body frame, be provided with in the valve body frame from the movable vane that hangs down, every both ends from the movable vane that hangs down all respectively are provided with a staff, and the movable vane that hangs down uses the staff as rotating the fulcrum, can open towards both sides, and valve body frame department is hugged closely to the both sides of staff, has respectively inlayed an angle bar, and every angle bar can the polar adjustment, and ninety degrees synchronous rotations around every side angle bar passes through synchronous pulley realization.
Synchronous pulley and hold-in range meshing, synchronous pulley pass through the hold-in range and realize synchronous rotation, and the synchronous pulley that is located the bottom side is connected with the motor.
The invention has the beneficial effects that: the one-way non-return air valve device controlled by the double-angle iron solves the problem that an electric air valve cannot control the air direction of the piston of the subway station, so that a subway station shield door and an open-close type environment control system are organically combined, the operation energy consumption of the station environment control system is effectively reduced, and the energy is saved.
