Abstract
The utility model discloses a soft connection air channel for a train set ventilation system in the field of air channel connection devices, which comprises two square flanges connected through soft connection, the soft connection and the two flanges are integrally combined to form a whole in vulcanizing mode, four corners of each flange are respectively provided with an installation hole, and the soft connection is a wave-shaped soft connection pipeline. By arranging the soft connection to be the wave-shaped soft connection pipeline, the soft connection air channel for the train set ventilation system ensures the normal work of the ventilation system when a vehicle is turning, can normally work under the condition of severe weather, prolongs service life, and can be used in a train set ventilation system.
Description
Technical field
The utility model relates to a kind of air channel connecting device, particularly a kind of train groups ventilation system.
Background technology
In recent years, the phenomenon that many city traffic block up had effectively been extenuated in city railway train fast developments such as domestic train; And through country vigorously support and make great efforts the exploitation; China's subway and track train technical merit have arrived international most advanced level, and some developing countries begin to use for reference China's experience, greatly develop subway and track traffic and directly buy from China subway and track train; Simultaneously along with the Chinese Urbanization's process is accelerated day by day; More medium-sized city constantly enlarges, and its traffic is day by day severe, also constantly joins rail friendshipization construction ranks.Because of the market demand increases, updating and upgrading of a product rhythm is accelerated, and each track train is manufactured enterprise and born very big pressure, all on production efficiency, exploits potentialities with all strength.
In the prior art; Be used for that the air channel that is flexible coupling of train groups ventilation system is general directly to be provided with being flexible coupling of flange through two ends the ventilation system between train is coupled together, its weak point is: when turning in the train driving process, a side that is flexible coupling is prone to stretch, opposite side is prone to extruding; Influence the performance in the air channel that is flexible coupling; And under the lower weather conditions of temperature, train is directly turned and is made the cracking that is flexible coupling easily, thereby influences the service life in the air channel that is flexible coupling.
The utility model content
The purpose of the utility model provides a kind of train groups ventilation system with the air channel that is flexible coupling, and making train when turning, be flexible coupling has certain cushion space, thereby has guaranteed the normal operation of ventilation system, has prolonged the service life in the air channel that is flexible coupling.
The purpose of the utility model is achieved in that a kind of train groups ventilation system is with the air channel that is flexible coupling; Comprise two through the continuous square flange that is flexible coupling; Saidly be flexible coupling and two flanges are whole is combined into one through sulfuration; All have mounting hole on four angles of said flange, said be flexible coupling be the corrugated pipeline that is flexible coupling.
Compared with prior art, the beneficial effect of the utility model is, the utility model is arranged to the ripple type pipeline that is flexible coupling through being flexible coupling; Make train in the turning process, a side in the air channel that is flexible coupling realizes compression, and opposite side is realized stretching; There is certain cushion space in the feasible air channel that is flexible coupling; Thereby guaranteed the normal operation of ventilation system, and can prolong the service life in the air channel that is flexible coupling in normal operation under the severe weather conditions.The utility model can be used in the train groups ventilation system.
For the ease of ventilation system being installed in the train top, do not take too much space, the said cross section ovalize that is flexible coupling.
In order to improve connection stability between the air channel in be flexible coupling air channel and the compartment, said flange is the inner rubber flange that is inlaid with metallic framework.
For the feasible air channel that is flexible coupling is adapted at work under the harsh environment more, the rubber that said rubber flange is selected for use is withstanding corrosion, ageing-resistant, cold-resistant, abrasion resistant butadiene rubber.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the birds-eye view of Fig. 1.
Fig. 3 is that the A-A of Fig. 2 is to section-drawing.
Wherein, 1 flange, 2 are flexible coupling, 3 mounting holes, 4 metallic frameworks.
The specific embodiment
A kind of train groups ventilation system shown in Fig. 1-3 is with the air channel that is flexible coupling; Comprise two through the 2 square flanges 1 that link to each other that are flexible coupling, be flexible coupling and two flanges 1 are whole is combined into one through sulfuration, all have mounting hole 3 on four angles of flange 1; Be flexible coupling and be corrugated 2 pipelines that are flexible coupling; Be flexible coupling 2 cross section ovalize, flange 1 is the inner rubber flange 1 that is inlaid with metallic framework 4, the rubber that rubber flange 1 is selected for use is withstanding corrosion, ageing-resistant, cold-resistant, abrasion resistant butadiene rubber.
The utility model is not limited to the foregoing description; On the basis of the disclosed technical scheme of the utility model; Those skilled in the art is according to disclosed technology contents; Do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in the protection domain of the utility model.
Claims (4)
1. a train groups ventilation system is with the air channel that is flexible coupling; Comprise two through the continuous square flange that is flexible coupling, saidly be flexible coupling and two flanges are whole is combined into one through sulfuration, all have mounting hole on four angles of said flange; It is characterized in that, said be flexible coupling be the corrugated pipeline that is flexible coupling.
2. a kind of train groups ventilation system according to claim 1 is characterized in that with the air channel that is flexible coupling, the said cross section ovalize that is flexible coupling.
