Description

一种双角铁控制的单向止回风阀装置One-way non-return air valve device controlled by double angle irons

技术领域technical field

本发明涉及一种风阀装置,特别是涉及一种地铁内屏蔽门上的垂直安装可调止回方向的风阀装置。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.

背景技术Background technique

地铁列车在运行时由于隧道空间有限会带动隧道空气产生高速流动,产生活塞风,而列车车厢的空调散热、列车与轨道的摩擦散热以及列车启动制动时散热会给隧道带来大量的热量。如果没有任何措施和手段,携带热量的活塞风会进出地铁站台内,造成空调季节地铁车站的空调能耗高,制冷设备的装机容量大,因此在夏季,要求地铁车站站台门系统上的风阀应是关闭的,起到隔绝隧道与站台之间热量传递的目的。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.

在冬季,地铁列车的行驶产热及制动产热使隧道内的温度高于地铁站台的温度,站台温度高于站厅温度,站厅温度又高于室外温度,活塞风中的热量是车站冬季采暖的免费热源,充分利用隧道内活塞风携带的热量提高地铁车站的温度,能够有效提高等车乘客的舒适度。因此,在冬季,要求空气流动的方向是隧道-站台-站厅-室外,保证冷空气不进入隧道。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.

而在过渡季节,地铁车站内的空调系统关闭,当室外温度低于地铁车站温度时,可以将室外空气引入车站内,这样能够有效降低地铁车站的机械通风能耗。此时,空气流动的方向是室外-站厅-站台-隧道,与冬季正好相反。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.

但是活塞风的方向是双向的,列车进站时活塞风从隧道进入车站,而列车离开车站时,活塞风又从车站流入隧道内,目前通过在屏蔽门上设置电动风阀的可调通风型站台门还不能有效解决过渡季节和冬季单向利用活塞风的问题。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.

具体实施方式Detailed ways

以下结合附图对本发明作进一步详细说明。The present invention will be described in further detail below in conjunction with the accompanying drawings.

图1是本发明双角铁控制的单向止回风阀装置的结构示意图;图4为风阀装置中同步轮系统的正视图;图5、图6、图7是风阀控制的原理图。如图1至图4所示,本发明的垂直安装可调节方向风阀装置,包括阀体框架1、自垂活动叶片2、角铁6及传动机构。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.

自垂活动叶片2可以向两个方向开启。每个自垂活动叶片2的两端都各设置有一个小轴3,自垂活动叶片2以小轴3为转动支点,可以朝两侧开启。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.

小轴3的两侧紧贴阀体框架1处,各嵌有一块角铁6,每块角铁6可以两极调节。角铁6都与同步带轮7连接,角铁6以同步带轮7为转动支点可以作前后九十度的转动。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.

同步带轮7与同步带8啮合,同步带轮7通过同步带8实现同步转动。位于底侧的同步带轮701与电机5连接。电机5转动带动同步带轮701转动,通过同步带8,同步轮7实现同步转动。同步轮7转动带动角铁6转动到垂直或是水平方向,从而使角铁6呈左开或是右开方向。如图5,当阀体一端的角铁601全部呈左开状态,另一端的角铁602全部呈右开状态,能够让自垂活动叶片2的回位起限制作用。角铁6可以通过两端同开一个方向的配合,从而使自垂活动叶片2只能朝一个方向开启。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.

如图6,两端的角铁6都右开,风阀左侧压力高于风阀右侧压力时,自垂活动叶片2朝右自动开启,从而实现由左向右的气流,当压力相反时自垂活动叶片自动关闭。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.

如图7,两端的角铁6都左开,风阀右侧压力高于风阀左侧压力时,自垂活动叶片2朝左自动开启,从而实现由右向左的气流,当压力相反时自垂活动叶片2自动关闭。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.

如图5,当阀体一端的角铁601全部呈左开状态,另一端的角铁602全部呈右开状态,风阀关闭。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.

尽管上面结合图对本发明进行了描述,但是本发明并不局限于上述的具体实施方式,上述的具体实施方式仅仅是示意性的,而不是限制性的,本领域的普通技术人员在本发明的启示下,在不脱离本发明宗旨的情况下,还可以作出很多变形,这些均属于本发明的保护之内。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.
