Operation principle：
After the fire-preventing check valve of the present invention installs, non-ventilation state, two panels check sheet is all covered in step housing 307
On, inside and outside it is basic there is no a gap, smoke-backflow-proof effect is preferable.
After lampblack absorber operation ventilation, fire resisting damper two panels check sheet will be opened, and the maximum angle that check sheet is opened is 80 °,
Anti- picker bar part makees structure limitation to its maximum angle, mainly prevents that the angle that check sheet is opened is excessive, translates into another side, no
It can turn back again.
Either cigarette machine ventilation state still non-ventilation state, on fire in flue when running into, fire prevention piece 14 will stretch, and two
Individual anti-picker bar 15 is acted on by the torsion of torsion spring 16, is all rotated down, and anti-picker bar 15 will withstand two check sheets, and check sheet will
Closing for a long time, prevent that timely cigarette machine is opened, check sheet can not also be opened, and can effectively prevent kindling material from being spread by flue to family,
It is thus safer.Fire resisting damper will not recover automatically in the case, could only recover to use manually.
The fire-preventing check valve of the present invention is double blade structure metal fireproof valve, each side there is a set of fire proof construction, can
To be applicable various flues, especially still there is preferable air performance in major-minor flue, also relatively safety, applicability is also more
Extensively.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of changes, modification can be carried out to these embodiments, replace without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
