Abstract
The utility model discloses a kind of ventilation shafts of people's air defense garage balanced ventilation comprising cuboid pipeline, both ends rectangle ring flange and partition；The sectional dimension of cuboid pipeline meets mean time ventilation smoke evacuation and requires；Partition is fixed in cuboid pipeline, cuboid pipeline is divided into upper section of tubing and lower section of tubing, the sectional dimension of upper section of tubing meets the requirement of wartime people's air defense clean ventilation；The rectangle ring flange at both ends is fixed on the both ends of cuboid pipeline.The utility model mean time ventilation smoke evacuation upper and bottom section pipeline is completely used for divulging information, and ventilation quantity is big, is able to satisfy the requirement of mean time ventilation smoke evacuation；In wartime people's air defense clean ventilation, passage portion ventilation is only used, people's air defense is become smaller with duct dimension, and wind speed increases, and dynamic pressure increases, and fresh air can be sent to system end, can meet balanced ventilation requirement.The utility model structure is simple, easy to use.
Description
Technical field
The utility model relates to a kind of ventilation shafts of people's air defense garage balanced ventilation.
Background technique
According to " fire safety rules is designed in garage, freight car temporary repairing shed, parking lot " the 8.2.3 articles of (GB50067-2014): machinery row
Cigarette system can be shared with the exhaust of people's air defense, health etc., ventilating system；The 5.3.3 articles of " Code for design of basement for civil air defence ": it presses
Maximum calculating fresh air volume selects clean ventilation pipeline.Existing design mode is that the air quantity discharged fume according to usually system ventilation is true
Determine air duct and air ports size, people's air defense air duct shares this air duct with usually system, and usually it is logical to be far longer than people's air defense cleaning for systematic air flow
Wind air quantity causes people's air defense clean ventilation wind speed too small, and dynamic pressure is too low, and fresh air can not reach system end, is unsatisfactory for balanced ventilation
Requirement.
Utility model content
The purpose of this utility model is to solve the above-mentioned problems in the prior art, and it is uniform to provide a kind of people's air defense garage
The ventilation shaft of air-supply, the ventilation shaft be both able to satisfy the requirement of wartime people's air defense cleaning uniform ventilation, while being also able to satisfy usually
The requirement of ventilation smoke exhaust.
To achieve the above object, the technical solution of the utility model is: a kind of ventilation duct of people's air defense garage balanced ventilation
Road comprising cuboid pipeline, both ends rectangle ring flange and partition；The sectional dimension of cuboid pipeline meets mean time ventilation
Smoke evacuation requires；Partition is fixed in cuboid pipeline, and cuboid pipeline is divided into upper section of tubing and lower section of tubing, top
The sectional dimension of subtube meets the requirement of wartime people's air defense clean ventilation；The rectangle ring flange at both ends is fixed on cuboid pipeline
Both ends.
The utility model increases partition, and cuboid pipeline is divided into upper and bottom section, mean time ventilation smoke evacuation by partition
Upper and bottom section pipeline is completely used for divulging information, and ventilation quantity is big, is able to satisfy the requirement of mean time ventilation smoke evacuation；In wartime people's air defense
When clean ventilation, passage portion ventilation is only used, people's air defense is become smaller with duct dimension, and wind speed increases, and dynamic pressure increases, and fresh air can be sent
Up to system end, balanced ventilation requirement can be met.The utility model structure is simple, easy to use.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described further in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, the present embodiment includes the rectangle ring flange 5 and partition 2 of cuboid pipeline 1, both ends.Cuboid pipe
The sectional dimension in road 1 meets mean time ventilation smoke evacuation and requires.Partition 2 is fixed in cuboid pipeline 1, and cuboid pipeline 1 is divided
At upper section of tubing 3 and lower section of tubing 4, the sectional dimension of upper section of tubing 3 meets the requirement of wartime people's air defense clean ventilation.Two
The rectangle ring flange 5 at end is fixed on the both ends of cuboid pipeline 1.
Above-described embodiment be only it is preferred and illustrative, those skilled in the art can carry out according to the description of this patent
The improvement of equivalent technologies, within the protection scope of the present patent.
