Description

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

technical field

The invention relates to a damper device, in particular to a damper device installed vertically on an inner screen door of a subway with adjustable check direction.

Background technique

Due to the limited space in the tunnel, the subway train will drive the air in the tunnel to generate high-speed flow and generate piston wind when the subway train is running. The air-conditioning heat dissipation of the train compartment, the friction heat dissipation between the train and the track, and the heat dissipation when the train starts to brake will bring a lot of heat to the tunnel. If there are no measures and means, the piston wind carrying heat will enter and exit the subway platform, resulting in high air-conditioning energy consumption in the subway station during the air-conditioning season, and the installed capacity of the refrigeration equipment is large. Therefore, in summer, the damper on the door system of the subway station platform is required It should be closed to isolate the heat transfer between the tunnel and the platform.

In winter, the heat produced by the running and braking of subway trains makes the temperature in the tunnel higher than the temperature of the subway platform, the temperature of the platform is higher than the temperature of the station hall, and the temperature of the station hall is higher than the outdoor temperature. The heat in the piston wind is the Free heat source for heating in winter, making full use of the heat carried by the piston wind in the tunnel to increase the temperature of the subway station, which can effectively improve the comfort of waiting passengers. Therefore, in winter, the direction of air flow is required to be tunnel-platform-station hall-outdoor to ensure that cold air does not enter the tunnel.

In the transition season, the air-conditioning system in the subway station is turned off. When the outdoor temperature is lower than the temperature of the subway station, outdoor air can be introduced into the station, which can effectively reduce the energy consumption of mechanical ventilation in the subway station. At this time, the direction of air flow is outdoor-station hall-platform-tunnel, just opposite to that in winter.

However, the direction of the piston wind is bidirectional. When the train enters the 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. Platform doors cannot effectively solve the problem of one-way utilization of piston wind in transitional seasons and winter.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings.

Fig. 1 is the structural representation of the one-way non-return air valve device controlled by double angle irons of the present invention; Fig. 4 is the front view of the synchronous wheel system in the air valve device; Fig. 5, Fig. 6 and Fig. 7 are schematic diagrams of air valve control . As shown in Fig. 1 to Fig. 4, the vertically installed adjustable direction air valve device of the present invention includes a valve body frame 1, a self-suspended movable blade 2, an angle iron 6 and a transmission mechanism.

The self-suspending movable vane 2 can be opened in two directions. Both ends of each self-suspended movable blade 2 are respectively provided with a small shaft 3, and the self-suspended movable blade 2 takes the small shaft 3 as a fulcrum of rotation and can be opened towards both sides.

Both sides of the small shaft 3 are close to the frame 1 of the valve body, each is embedded with a piece of angle iron 6, and each piece of angle iron 6 can be adjusted at two poles. Angle iron 6 is all connected with synchronous belt pulley 7, and angle iron 6 can do front and rear ninety degree of rotations with synchronous belt pulley 7 as rotation fulcrum.

The synchronous pulley 7 is meshed with the synchronous belt 8, and the synchronous belt 8 realizes the synchronous rotation of the synchronous pulley 7. The synchronous pulley 701 on the bottom side is connected with the motor 5 . The rotation of the motor 5 drives the synchronous pulley 701 to rotate, and through the synchronous belt 8, the synchronous wheel 7 realizes synchronous rotation. The rotation of the synchronous wheel 7 drives the angle iron 6 to rotate to a vertical or horizontal direction, so that the angle iron 6 is left or right. As shown in Fig. 5 , when the angle irons 601 at one end of the valve body are all left-opened, and the angle irons 602 at the other end are all right-opened states, the return of the self-suspending movable vane 2 can be restricted. The angle iron 6 can be opened in one direction through the cooperation of both ends, so that the self-suspending movable blade 2 can only be opened in one direction.

As shown in Figure 6, the angle irons 6 at both ends are opened to the right. When the pressure on the left side of the damper is higher than the pressure on the right side of the damper, the self-suspending movable blade 2 will automatically open to the right, thereby realizing the airflow from left to right. When the pressure is opposite The self-suspended movable blades are automatically closed.

As shown in Figure 7, the angle irons 6 at both ends are left open. When the pressure on the right side of the damper is higher than the pressure on the left side of the damper, the self-suspended movable blade 2 will automatically open to the left, thereby realizing the airflow from right to left. When the pressure is opposite The self-suspending movable blade 2 is automatically closed.

As shown in Figure 5, when all the angle irons 601 at one end of the valve body are left open and all the angle irons 602 at the other end are right open, the air valve is closed.

Although the present invention has been described above in conjunction with the drawings, the present invention is not limited to the above-mentioned specific embodiments, and the above-mentioned specific embodiments are only illustrative, rather than restrictive. Under the inspiration, many modifications can be made without departing from the gist of the present invention, and these all belong to the protection of the present invention.
