Abstract
The utility model relates to a fully-sealed flue check valve. The fully-sealed flue check valve comprises a valve body and a reducing part, wherein the valve body is connected with the reducing part and form a split type structure, a cover plate is movably connected onto the valve body, and the valve body comprises a valve plate, a first smoke hatch and a second smoke hatch. The first smoke hatch and the second smoke hatch are respectively and correspondingly arranged on two sides of the valve plate, the first smoke hatch is connected with the reducing part, the periphery of the lower portion of the cover plate is provided with a sealing groove, and a magnet is installed on the sealing groove. The fully-sealed flue check valve is quick and convenient to install and good in sealing effect.
Description
Technical field
The utility model relates to a kind of hermetically sealed check valve for flue.
Background technique
Existing check valve for flue reducing and valve body are all-in-one-piece or the triad formula, install inconveniently, and sealing effect is bad, fall cigarette easily.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of easy for installation, and the hermetically sealed check valve for flue of good seal performance, realizes that the technological scheme of above-mentioned purpose is as follows:
Hermetically sealed check valve for flue is characterized in that: comprise valve body, reducing, valve body is connected with reducing, and valve body and reducing are split-type structural, is connected with cover plate on the valve body.
Further, described valve body comprises valve plate, smoke hatch one, smoke hatch two, and described smoke hatch one and smoke hatch two be corresponding both sides that are arranged in valve plate respectively, and smoke hatch one is connected with reducing.
Further, described reducing is a cylinder-like structure, and the reducing the inside has a groove, is connected with smoke-ejecting pipe, and the reducing internal diameter is inserted on smoke hatch one external diameter, and close-fitting connects, and smoke hatch one external diameter and reducing internal diameter adapt.
Further, described cover plate adopts single flabellum valve plate, and the cover plate lower edge has seal groove.
Further, a side of cover plate is movably connected in the internal diameter top of smoke hatch two by positioning shaft.
Further, on the seal groove magnetite is installed below corresponding with positioning shaft the cover plate.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
Valve body 1 is split-type structural with reducing 2, be connected with cover plate 3 on the valve body 1, one side of cover plate 3 is movably connected in the internal diameter top of smoke hatch 1-3 by positioning shaft 5, valve body comprises valve plate 1-1, smoke hatch one 1-2, smoke hatch two 1-3, smoke hatch one 1-2 and smoke hatch two 1-3 sizes adapt to, described smoke hatch one 1-2 and smoke hatch two 1-3 are corresponding both sides that are arranged in valve plate 1-1 respectively, smoke hatch one 1-2 is connected with reducing 2, reducing 2 is a cylinder-like structure, the reducing the inside has a groove 2-1, be connected with smoke-ejecting pipe, the reducing internal diameter is inserted on the external diameter of smoke hatch one 1-2, and external diameter and the reducing internal diameter of smoke hatch one 1-2 adapt, and close-fitting connects, cover plate 3 adopts single flabellum valve plate, and on the side edge thereof below of 5 corresponding of positioning shafts magnetite 4 is installed.Cover plate adopts single flabellum cover plate, and the flue exit ventilated port is big, and performance of ventilating is stronger.
The external diameter of cover plate 3 and smoke hatch two 1-3 internal diameters adapt, cover plate 3 lower edge have the seal groove (not shown), smoke hatch two sealings are covered, prevent down cigarette, the small-sized magnetite of installing on the seal groove below the cover plate 34, can hold cover plate 3 on the one hand, cover plate 3 can not backed down by down draught easily, and the effect that utilizes magnetite can produce magnetic force makes cover plate 3 close more sealing on the one hand, and it is gradient that cover plate 3 is closed, valve body 1 can be installed on the body of wall of floss hole earlier, reducing and smoke-ejecting pipe are connected, overlap upper valve body 1 again, install more convenient, also removablely clean and change, easy to use.
It below only is the utility model embodiment's preferred embodiment; not in order to limit the utility model embodiment; all within the utility model embodiment's spirit and principle; any modification of doing, be equal to replacement, improvement etc., all should be included in the utility model embodiment's the protection domain.
