Abstract
Self-opening type exhaust outlet belongs to the category that energy saving building VMC utilizes conveyance system.Including cylinder, flap valve, grid, it is characterized in that：Cylinder is the rounded or square cylinder in section, in put one or multi-channel support base, stopper slot is reserved at two ends；Reserve spacer pin in flap valve both sides；Grid is that the filter screen being made of metal or plastics is used for stopping that foreign object is invaded；Cylinder is preset in the reserved wall hole of building, and the spacer pin of flap valve is assemblied in the support base reserved in cylinder, the stopper slot assembling grid at cylinder two ends.The utility model with smooth discharge foul indoor air, can not result in the blower fan normal work of the big influence VMC of room air pressure.
Description
Technical field
The utility model belongs to the category that energy saving building VMC utilizes conveyance system.
Background technology
Nowadays, increasingly severe with ecological environment, the seriousness of haze makes people, and everyone finds himself in danger, then many places
Energy-saving building is increasingly favored, particularly the utilization of VMC, makes many buildings that door and window has all been made into totally enclosed type,
The air-tightness of so building has had a strong impact on the operating efficiency of VMC, and design is simple and easy to apply particularly must from air exhausting device
Will.
Utility model content
Needed for described above, spy devises self-opening type exhaust outlet.
Solution of the present utility model is：Self-opening type exhaust outlet, including cylinder, flap valve, grid, it is characterized in that：Cylinder
The rounded or square cylinder in section, in put one or multi-channel support base, stopper slot is reserved at two ends；Reserve spacing in flap valve both sides
Pin；Grid is that the filter screen being made of metal or plastics is used for stopping that foreign object is invaded；Cylinder is preset in the reserved wall hole of building,
The spacer pin of flap valve is assemblied in the support base reserved in cylinder, the stopper slot assembling grid at cylinder two ends.
As described above, flap valve section is more than cylinder inner section, and the slightly top assembling of spacer pin, be so conducive to flap valve can
Self-return.
As described above, indoor, because VMC strength injection fresh air, room pressure increase, door and window air-tightness is again fine,
The big foul indoor air of pressure can push flap valve open, be discharged out of cylinder, and VMC is stopped, and indoor and outdoor air pressure maintains an equal level,
Return is sealed flap valve under gravity, and outside foul atmosphere can not be invaded.
The beneficial effect of the utility model is：The utility model can not result in room with smooth discharge foul indoor air
The blower fan normal work of the big influence VMC of inner air pressure.
Brief description of the drawings
The utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the utility model structural representation.
The grid of 1 cylinder, 11 support base, 12 stopper slot, 2 flap valve, 21 spacer pin 3 in figure.
Embodiment
Self-opening type exhaust outlet, including cylinder（1）, flap valve（2）, grid（3）, it is characterized in that：Cylinder（1）It is that section is rounded
Or square cylinder, in put one or multi-channel support base（11）, stopper slot is reserved at two ends（12）；Flap valve（2）Reserve spacing in both sides
Pin（21）；Grid（3）It is that the filter screen being made of metal or plastics is used for stopping that foreign object is invaded；Cylinder（1）It is preset in building pre-
In the wall hole stayed, flap valve（2）Spacer pin（21）It is assemblied in cylinder（1）Interior reserved support base（11）It is interior, cylinder（1）Two ends
Stopper slot（12）Assemble grid（3）.
As described above, flap valve（2）Section is more than cylinder（1）Inner section, and spacer pin（21）Slightly top assembling, it is so favourable
In flap valve（2）Being capable of self-return.
As described above, indoor, because VMC strength injection fresh air, room pressure increase, door and window air-tightness is again fine,
The big foul indoor air of pressure can push flap valve open（2）, from cylinder（1）Interior discharge, VMC is stopped, indoor and outdoor air pressure
Maintain an equal level, flap valve（2）Return is sealed under gravity, and outside foul atmosphere can not be invaded.
