Description
Technical field
The utility model relates to kitchen and bath's flue gas process fields, and in particular to a kind of flue check device.
Background technique
Currently, the exhaust duct in kitchen and bath is mostly through type, in the kitchen using longitudinal public gas flue, generally it is not provided with
Airflow exits control valve causes the flue gas in public gas flue to be easy to flow backwards to lack effective control to institute's discharge gas
To kitchen；Once the toxic hot fume of flame combustion and its generation will be diffused to along exhaust duct in addition, kitchen and bath is caught fire
In the public longitudinal exhaust duct in residence building, to cause biggish casualties and damage to property.It therefore, need to be in range hood and public
Check device is arranged between gas flue to be obstructed.When public gas flue or kitchen and bath are caught fire, the valve of existing check device without
Method closes and makes flame or toxic hot fume along exhaust pipe crossfire, is diffused into other unburned spaces of building, rises not
To the fireproofing function for blocking, controlling flame or the diffusion of toxic hot fume.
Utility model content
For the defects in the prior art, it the purpose of the utility model is to provide a kind of flue check device, can be avoided
Flue gas is flow backwards can play good flameproof effect simultaneously.
The technical scheme adopted by the utility model is a kind of flue check device, including guide shell and flue gas non-return group
Part；The port of the guide shell is hinged with check-valve cap, the port of check-valve cap openable guide shell in gas shock；It is described
Flue gas non-return component includes the fixed block in guide shell；Fixed block is equipped with male part, and the male part is equipped with to solid
Determine the mounting rod of block extending direction arrangement, the U-shaped block that can be rotated around mounting rod is cased on the mounting rod, the mounting rod runs through
