Background technology
Rail vehicle is equipped with air-conditioning equipment, and processed air and outdoor fresh air are conveyed into guest room, and fresh air is held
Continuous introducing can cause internal pressure in guest room to increase.To ensure in-car air quality and keep constant air pressure, improving air-conditioner efficiency and multiplying
Comfort level is sat, the exhaust gas of interior equivalent fresh air need to be discharged.
The exhaust emission device for rail vehicle of early stage is there are two types of form, and one, natural exhaust, that is, pass through window or vehicle
The shortcomings that body opening installation air duct, directs out discharge exhaust gas, this form is indoor and outdoor air in connected state, room air
Pressure changes with air pressure variations outside vehicle, and in tunnel, meeting, instantaneous pressure variation can often cause greatly very much seating people in room
Member is uncomfortable.2nd, air draft is forced, i.e., indoor exhaust air pressure is drained into outdoor using wind turbine.The shortcomings that this form, is continuous for wind turbine
Work can lead to too low room pressure, increase electrical safety risk and increase energy consumption.
Invention content
The purpose of this utility model is to overcome above-mentioned deficiency provides the self-adjustable exhaust gas discharge of Split type track vehicle
Device.
What the purpose of this utility model was realized in：
The automatic adjusting exhaust emission device of Split type track vehicle, its main feature is that：It includes outer cover, inner cover, seal felt, close
Air inlet is provided on envelope felt, inner cover is located in outer cover, and air draft chamber is formed between inner cover and outer cover, and " Ω " shape is provided on inner cover
Clip, between inner cover and outer cover, the top of clip is connect clip with outer cover, and following and inner cover, the seal felt of clip are connect,
Inner cover is located in the framework that clip is formed with seal felt, and inner cover includes inclined-plane and faces directly, and exhaust outlet is provided on inclined-plane, is gone back on inclined-plane
It is provided with from air register, from the upper end of air register and inclined-plane upper articulation, the exhaust outlet pair from the size and inclined-plane of air register
Should, weather shield is in " √ " shape, and one end straight flange of weather shield is connect with facing directly, and the other end bevel edge of weather shield is located at inner cover and outer cover
In the air draft chamber of formation.
A kind of automatic adjusting exhaust emission device of Split type track vehicle of the utility model, the self-regulated with inclined-plane upper articulation
Air door can rely on the exhaust outlet that its own gravity is closed on inclined-plane.
A kind of automatic adjusting exhaust emission device of Split type track vehicle of the utility model, the row that inner cover is formed with outer cover
Wind intracavitary is provided with screen pack.
Compared with prior art, the beneficial effects of the utility model are：
1. the utility model is hinged from air register in inner cover exhaust outlet.When car is pressed greatly without positive pressure or vehicle external pressure with car
During power, from air register, closing air outlet, prevention extraneous air into the car, prevent interior pressure with pressure outside under its own weight
Fluctuation；It after interior air pressure rises to form positive pressure, will be pushed open automatically from air register, discharge exhaust gas.Interior air pressure is higher, self-regulated
The angle that air door is opened is bigger, and the exhaust gas of discharge is also more, so as to keep interior barotropic equilibrium.
2. the utility model is provide with is equipped with weather shield inside, weather shield is in " √ " shape, can stop that extraneous sleet splashes
Into the car, and ponding water conservancy diversion can be made to go out inner cover.
3. the utility model outer cover, inner cover and seal felt are connected by clip, when exhaust emission device breaks down
When needing maintenance, the fastening bolt that need to only remove on clip can detach outer cover, inner cover and seal felt, not only installation side
Just, and convenient for safeguarding.
