Abstract
The utility model discloses a fireproof flue check valve which comprises a panel and a flue pipe, wherein the rear end surface of the flue pipe is provided with a connecting plate and a non-return plate which is connected with the connecting plate through a pin shaft, the non-return plate is matched with the shape of the rear end surface of the flue pipe, the inner side of the rear end surface of the flue pipe is fixedly provided with a clamping seat, a rotary fireproof rod is installed on the clamping seat, the clamping seat is provided with a torsion spring for fixing the fireproof rod, and the fireproof rod is clung to the inner wall of the flue pipe through a fuse link which is fixed on the flue pipe. By adopting the structure, because of the low fusion point characteristic of the fuse link, the fuse link is fused in fire, and the fireproof rod pushes against the check valve under the acting force of the torsion spring, so that the fire or smoke in a fire area can be prevented from being discharged to a common flue or entering a non-fire area through a valve body passage.
Description
Technical field
The utility model relates to a kind of check valve, especially a kind of family kitchen fire-proof flue check valve.
Background technique
high level or multi-storey building are provided with air exhaust channel, and the kitchen at each family is provided with the interface identical with this air exhaust channel in the building, the outlet valve of the smoke-ejecting pipe of kitchen range hood by being loaded on this interface is by being connected with air exhaust channel, the cooking fume that kitchen ventilator absorbs is pushed valve open, thereby being concentrated from the air channel by the smoke exhaust of corridor, cooking fume discharges, at present this for the characteristics of the outlet valve of air exhaust channel interface is, solved the problem that air-flow in gas flue liquidates and easily pours in down a chimney when causing the smooth and smoke evacuation of smoke evacuation, but, can not effectively prevent the fire of conflagration area, flue gas by the oil smoke road to non-conflagration area play, and then cause non-conflagration area breaking out of fire.
The model utility content
The purpose of this utility model is to provide a kind of fire-proof flue check valve, under normality, only allow flue gas from the unidirectional discharging of valve body intake grill, when fire occurs, retaining board can be withstood, and prevents that the fire of conflagration area or flue gas from discharging or entering non-conflagration area from valve channel to common flue.
For achieving the above object, the technical solution of the utility model is: a kind of fire-proof flue check valve, comprise panel, flue tube, be provided with connecting plate on the flue tube ear end face, the retaining board that is connected with connecting plate by bearing pin, retaining board and flue tube ear end face shape are coincide, flue tube ear end face inboard is installed with a deck, a rotatable anti-picker bar is installed on deck, be provided with the torsion spring of a fixing anti-picker bar on deck, anti-picker bar is close on the flue tube inwall by the fuse link that is fixed on flue tube.
All component of described anti-fire check valve are made by metallic material.
The beneficial effects of the utility model are: after adopting the utility model structure, low melting point characteristic due to fuse link, when fire occurs, fuse link fusing, anti-picker bar is under the active force of torsion spring, withstand check valve, prevent that the fire of conflagration area or flue gas from discharging or entering non-conflagration area from valve channel to common flue.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model deck structural representation.
In figure: panel 1, flue tube 2, retaining board 3, bearing pin 4, connecting plate 5, deck 6, torsion spring 7, anti-picker bar 8, fuse link 9.
Embodiment
Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the utility model is described further.
Embodiment:
As shown in Figure 1 and Figure 2, a kind of fire-proof flue check valve, comprise panel 1, flue tube 2, be provided with connecting plate 5 on flue tube 2 ear end faces, the retaining board 3 that is connected with connecting plate 5 by bearing pin 4, retaining board 3 coincide with flue tube 2 ear end face shapes, flue tube 2 ear end face inboards are installed with a deck 6, a rotatable anti-picker bar 8 is installed on deck 6, be provided with the torsion spring 7 of a fixing anti-picker bar 8 on deck 6, anti-picker bar 8 is close on flue tube 2 inwalls by the fuse link 9 that is fixed on flue tube 2.
All component of described anti-fire check valve are made by metallic material.
The utility model check valve for flue adopts the port closed form, be provided with connecting plate 5 at flue tube 2 port tops, retaining board 3 tops are hinged on connecting plate 5 by bearing pin 4, anti-picker bar 8 one ends are fixed on flue tube 2 inwalls by fuse link 9, when peripheral temperature sharply rises, fuse link 9 fractures, torsion spring 7 drive anti-picker bar 8 rotations and withstand retaining board 3, prevent that the fire of conflagration area or flue gas from discharging or entering non-conflagration area from valve channel to common flue.
