Description

One-way non-return air valve device controlled by double-angle iron

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.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

FIG. 1 is a schematic structural view of a dual angle iron controlled one-way air check valve device of the present invention; FIG. 4 is a front view of a synchronizing wheel system in the damper assembly; fig. 5, 6, and 7 are schematic diagrams of the damper control. As shown in fig. 1 to 4, the vertically-installed direction-adjustable air valve device of the present invention includes a valve body frame 1, a self-hanging movable vane 2, an angle iron 6 and a transmission mechanism.

The self-dropping movable vane 2 can be opened in both directions. Both ends of each self-hanging movable blade 2 are respectively provided with a small shaft 3, and the self-hanging movable blades 2 can be opened towards both sides by taking the small shafts 3 as rotating fulcrums.

Two sides of the small shaft 3 are tightly attached to the valve body frame 1, and are respectively embedded with an angle iron 6, and each angle iron 6 can be adjusted in two poles. The angle iron 6 is connected with the synchronous pulley 7, and the angle iron 6 can rotate back and forth ninety degrees by taking the synchronous pulley 7 as a rotation fulcrum.

Synchronous pulley 7 meshes with hold-in range 8, and synchronous pulley 7 realizes synchronous rotation through hold-in range 8. The timing pulley 701 on the bottom side is connected to the motor 5. The motor 5 rotates to drive the synchronous belt wheel 701 to rotate, and the synchronous wheel 7 realizes synchronous rotation through the synchronous belt 8. The synchronous wheel 7 rotates to drive the angle iron 6 to rotate to the vertical or horizontal direction, so that the angle iron 6 is in the left-open or right-open direction. As shown in fig. 5, when all the angle bars 601 at one end of the valve body are left-opened and all the angle bars 602 at the other end are right-opened, the return of the self-hanging movable vane 2 can be restricted. The angle iron 6 can be matched with both ends in one direction, so that the self-hanging movable vane 2 can be opened only in one direction.

As shown in fig. 6, the angle iron 6 at both ends is opened to the right, when the left pressure of the air valve is higher than the right pressure of the air valve, the self-hanging movable vane 2 is automatically opened towards the right, thereby realizing the air flow from the left to the right, and when the pressures are opposite, the self-hanging movable vane is automatically closed.

As shown in fig. 7, when the angle iron 6 at both ends is opened to the left and the pressure at the right side of the air valve is higher than the pressure at the left side of the air valve, the self-hanging movable vane 2 is automatically opened towards the left, thereby realizing the air flow from the right to the left, and when the pressures are opposite, the self-hanging movable vane 2 is automatically closed.

As shown in fig. 5, when all the angle bars 601 at one end of the valve body are left-opened and all the angle bars 602 at the other end are right-opened, the air valve is closed.
