Abstract
The invention discloses a check valve with double fireproof valves for a smoke flue, which comprises a valve body, a sealing valve and a spring and is characterized in that the valve body is divided into a main valve body and an auxiliary valve body; and the auxiliary valve body is placed in the main valve body and is assembled with the main valve body in a matching manner. The check valve has the advantages that the fireproof valves of the check valve have the function of leading smoke upwards, no smoke backflow can be generated, and the smoke-blocking and fireproof effects are good; and moreover, the big flue is not required, so that the building weight can be reduced, the kitchen space is enlarged, and the construction cost is reduced.
Description
Technical field
The present invention relates to the stifled cigarette fire prevention of flue, specifically a kind of flue of public kitchen system fire prevention bivalve safety check.
Background technique
Flute check valve is the stifled fiery instrument of the vertical general stifled cigarette of shared gas-flue system each household family, along with people's growth in the living standard, requirement to flute check valve is more and more higher, existing flute check valve is various in style, generally formed by valve body and seal valve, by being arranged on the stifled cigarette of seal valve in valve body front end.This valve seal poor-performing, leakiness cigarette, there is no fire-proof function, also by being formed by valve body, spring and dissolver, by being arranged on the spring and the dissolver being connected with spring outside valve body front end, when after flue internal combustion fire, when temperature reaches more than 70 DEG C, after dissolver dissolves, spring is just pushed down seal valve, reaches the effect of fire-proof smoke-proof.This valve has the effect of fire-proof smoke-proof, but dissolver is can not dissolve time, just do not had the effect of fire-proof smoke-proof, and do not drawn upwards function of cigarette, larger flue tube cigarette also can pour in down a chimney.
Summary of the invention
The object of the invention is for having overcome the deficiencies in the prior art, and a kind of flue fire prevention bivalve safety check is provided, the fire-closing valve of this safety check has and draws cigarette function upwards, can not produce cigarette pours in down a chimney, stifled cigarette flameproof effect is good, and flue do not need so greatly, can alleviate building weight, expand kitchen space, reduce construction cost.
Object of the present invention realizes by following technical solution:
A kind of flue fire prevention bivalve safety check, comprises valve body, seal valve and spring, and unlike the prior art: valve body is divided into main valve body and auxiliary valve body, auxiliary valve body is placed in main valve body, mates the equipped flue bivalve safety check that becomes with main valve body.
Described main valve body is one and is the little cylindrical cavity broad in the middle in two, the outer nearly chimney of cavity place is provided with square projection, the smoke outlet place of cavity is arranged to arch door shape, be provided with the supporting plate of accepting auxiliary valve body on the base of arch door shape, be provided with on main valve body front end right side be connected with main valve body manually open valve rod.
Described main valve body can also be: rear end is entered the smoke-ejecting pipe jointing of mouth and smoke extractor and is arranged to circle, and remaining part to front end is arranged to tetragonal structure, and fire-closing valve top is arranged to square structure too.
Described auxiliary valve body by faded to by circle square enter mouth with enter the secondary valve body that mouth is connected and form, the secondary valve body square box that two right angle faces of clamping seal valve and two right angle faces of clamping fire-closing valve are socketed to form of serving as reasons, seal valve is box-shaped, its upper end is connected by seal valve connecting rod with square box top on one side, fire-closing valve is arch door shape, its bottom is connected by fire-closing valve connecting rod with the square box base on seal valve opposite, between fire-closing valve and seal valve, be provided with connecting rod, connecting rod two ends are flexibly connected with the connecting rod pedestal of the center upper portion that is located at fire-closing valve with the connecting rod pedestal of the lower central that is located at seal valve respectively.
The invention has the advantages that:
1. seal valve and fire-closing valve are to be flexibly connected interlock by connecting rod, in the time that seal valve is opened in smoke extractor wind, fire-closing valve is pushed open with regard to sealed valve, the automatic retraction of the not smoking calm time fire prevention of awaiting orders, can competent stifled cigarette and two kinds of tasks of fire prevention, cigarette can not pour in down a chimney with flue in profit can not pour in down a chimney to oneself kitchen yet.
2. the fire-closing valve of this flute check valve is can draw cigarette upwards, and when smoking, fire-closing valve is just opened, fire-closing valve automatic drawing back again when smoking.
3. because fire-closing valve can draw cigarette upwards, flue tube can it goes without doing main flue channel and auxillary flue, flue tube can be so large, can do bottom flue and can make again kitchen expansion space.
If to winter fire-closing valve and seal valve by freezing knot, can be with manually driving valve.
