Abstract
The utility model relates to a closed fireproof door, comprising a reverse smoke prevention pipe which is arranged on the inner wall of a flue and has a closed bottom end; a fireproof door is fixed on the inner wall of one side of the reverse smoke prevention pipe, close to the flue; a door plate of the fireproof door is upturned and fixed by a fireproof inductor; and a flue gas hole of the fireproof door is communicated with a check valve which is fixed on the outer wall of the flue. The fireproof door is arranged on the inner wall of the flue, so that the phenomena of flue gas backflow, flue gas drifting and the like can be effectively prevented, and the spreading of fire can be effectively stopped.
Description
Technical field
The utility model relates to a kind of closed labeled door.
Background technology
Residence discharge flue is vertical centralized common duct at present; Each resident family sends into oil smoke gas in the gas flue with smoke exhaust and discharges; The centralized public gas flue of this kind structure usually can produce flue gas because of blowing and pour in down a chimney, or produces the phenomenon that neighbour's's flue gas seals in, and causes cross pollution.When the dwelling house breaking out of fire, high-temperature flue gas also can quicken fire spread through the diffusion of centralized flue to other floor.
Summary of the invention
The purpose of the utility model provides a kind of closed labeled door, and it is installed in the gas flue inwall, can prevent phenomenons such as flue gas pours in down a chimney, flue gas seals in effectively, can also cut off spreading of fire effectively.
The said closed labeled door of the utility model; Comprise and be installed in the anti-down smoke pipe road gas flue inwall, the bottom sealing; Anti-down smoke pipe road is fixed with labeled door near the inwall of gas flue one side; Turn on the door-plate of labeled door and fix with the fire prevention inductor, the smoke hole of labeled door is communicated with the flap valve that is fixed on the gas flue outer wall.
Anti-down cigarette fan blade is equipped with in upper end, described anti-down smoke pipe road.
Be fixed with junction plate between described labeled door and the flap valve.
The utility model has the advantages that:
1. the utility model is provided with the anti-down smoke pipe road of lower end closed, and anti-down cigarette fan blade is equipped with in upper end, anti-down smoke pipe road, and during the lampblack absorber smoke evacuation, anti-down cigarette fan blade opens wide naturally, lets oil smoke pass through; When lampblack absorber was closed, anti-down cigarette fan blade fell naturally, closed anti-down smoke pipe road, can prevent to cause oil smoke gas to scurry the generation of phenomenon mutually because of the reason that wind-fall is irritated or each tame smoke exhaust ventilator power does not wait.
2. the utility model is equipped with flap valve, can prevent for the second time that flue gas from flowing backwards.
3. the fire prevention inductor of the utility model is the market outsourcing piece, and this inductor can nature fusing when meeting high temperature of fire, the door-plate that turns over is fallen and labeled door is closed.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe:
Fig. 1 is the structural representation of the said closed labeled door of the utility model;
Fig. 2 is the scheme of installation of the said closed labeled door of the utility model.
The specific embodiment
Like Fig. 1, shown in Figure 2; This closed labeled door comprises and is installed in anti-down smoke pipe road 2 gas flue 1 inwall, bottom sealing; Anti-down cigarette fan blade 8 is equipped with in 2 upper ends, anti-down smoke pipe road, and anti-down smoke pipe road 2 is fixed with labeled door 3 near the inwall of gas flue 1 one sides, turns on the door-plate 4 of labeled door 3 and fixing with fire prevention inductor 5; The smoke hole 6 of labeled door 3 is communicated with the flap valve 7 that is fixed on gas flue 1 outer wall, is fixed with junction plate 9 between labeled door 3 and the flap valve 7.
During use, the range hood pipeline of resident family is connected with flap valve 7.Wherein, fire prevention inductor 5 is the market outsourcing piece, and fire prevention inductor 5 can fuse by nature when meeting high temperature of fire, makes the door-plate 4 that turns over fall and labeled door 3 is closed.Flap valve 7 also is the market outsourcing piece.During the range hood smoke evacuation, anti-down cigarette fan blade 8 opens wide naturally, lets oil smoke pass through; When range hood cut out, anti-down cigarette fan blade 8 fell naturally, closed anti-down smoke pipe road 2, can prevent to cause oil smoke gas to scurry the generation of phenomenon mutually because of the reason that wind-fall is irritated or each tame smoke exhaust ventilator power does not wait.
