Abstract
The utility model discloses a public flue accessory in a building, in particular to a novel fireproof check valve for a flue, which comprises a circular valve body; a ventilation door, a fixed catch and a non-return barrier strip are arranged in the valve body, a pressure spring is arranged between the non-return barrier strip and the valve body, and the ventilation door is connected with the non-return barrier strip through a hinge. As the valve body is circular, the valve body is in joint with a wall body for good tightness; the material is saved; and the pressure spring is arranged between the non-return barrier strip and the valve body, so that the ventilation door can drop off quickly under too high temperature, and the fireproof effect is good.
Description
Technical field
The utility model relates to a kind of building flue additional device, especially is a kind of novel flue fire-preventing check valve.
Background technique
The flue safety check claims the interior wall blast cap again, in modern housing construction, has obtained extensive use.It can stop in the public flue poisonous fume of discharging in he other and oil smoke to pour in down a chimney to enter in the own home, also can prevent winged insects such as mosquito, moth, fly simultaneously effectively, and reptile such as gecko enters family.Present flue safety check comprises a valve body, is provided with air door in the valve body, and air door relies on self gravitation and valve body to be closed condition under nature, avoids the oil smoke in the public flue to enter the kitchen; When range hood is opened, to open automatically at the blast lower wind door, the oil smoke that the user produces enters in the public flue; Present flue fire-preventing check valve profile is square, during installation and wall applying leakproofness poor, secondly and not attractive in appearance, waste material is temperature when too high, air door comes off slower, flameproof effect is not good.
The model utility content
For overcoming above-mentioned technical problem, it is a kind of simple in structure that the utility model provides, the novel flue fire-preventing check valve that flameproof effect is good.
For realizing above-mentioned technical purpose, the utility model is achieved through the following technical solutions: the novel flue fire-preventing check valve, comprise a valve body, the valve body periphery is provided with the installation jump ring, valve body is provided with valve pocket, be provided with air door in the valve pocket, the periphery on air door top is provided with fixedly catch, valve body is provided with a check blend stop, the check blend stop is positioned at above position, the air door center of circle, and check blend stop one end is hinged on the valve body by fixed base, and the other end is hinged by fuse link and fixed base, be provided with a pressure spring between check blend stop and the circular valve, air door links to each other by hinge with the check blend stop.Described valve body is a circular valve.Described fuse link employing fusing point is 150 ℃ a fuse link.
The utility model is compared with conventional art, has following beneficial effect: the valve body profile is for circular, and is good with body of wall applying leakproofness, and saves material, is provided with pressure spring between check blend stop and the valve body, can come off fast after temperature is too high, and flameproof effect is good.
