Abstract
The utility model relates to a full sealing type check valve for a cooking fume remover, comprising a valve body with a circulation hole and two valve sheets which are rotatablely connected. The utility model is characterized in that the sealing periphery of the circulation hole of the valve body is provided with a sealing ring made of magnetic material or ferromagnetic material, and a flexible sealing structure is arranged between the two valve sheets made of the magnetic material or the ferromagnetic material. The utility model has the advantages that the closing and the sealing of the valve can be completely realized, and the smoke gas in a flue of a storied building can not back flow to a kitchen when passing a cooking fume remover.
Description
The utility model belongs to a kind of gas piping safety check, the hermetically sealed safety check of particularly a kind of range hood.
At present, home-use range hood adopts two butterfly sheet shape safety check in order to prevent the refluence of flue gas more, and two butterfly sheet is fixed on the valve body by the rotating shaft of self respectively, and when range hood was started shooting, wind-force blew valve block and erects, at this moment valve open; After shutdown, valve block falls after rise automatically by self gravitation, at this moment valve closing.Behind the valve closing, because valve is lighter, or the out-of-flatness of valve block edge, adding that no external force forces the valve block edge closely to contact with valve body, can exist slit in both connecting parts this moment.In addition, because big slit is arranged between two rotating shafts of two valve blocks, there is not seal approach.Above-mentioned two class slits are the main causes that cause flue gas to flow backwards.
The purpose of this utility model provides the hermetically sealed safety check of a kind of range hood, can realize the sealing of closing of valve fully, and the flue gas of stopping in the building flue flows back in the kitchen by range hood.
The purpose of this utility model is achieved in that and comprises the valve body of being with opening and rotate two valve blocks that connect that its technological scheme main points are: the opening seal perimeter place of valve body is provided with the seal ring of magnetic material or ferromagnetic material; Between two valve blocks of magnetic material or ferromagnetic material flexible sealing structure is set.
The utility model has the advantages that; Can realize the sealing of closing of valve fully, the flue gas of stopping in the building flue flows back in the kitchen by range hood.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model embodiment 1 structural representation.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the utility model embodiment 2 structural representations.
Fig. 4 is the utility model embodiment 3 structural representations.
Fig. 5 is the plan view of Fig. 4.
See Fig. 1, embodiment's 1 concrete structure is as follows: the be fixedly connected seal ring 3 of magnetic or ferromagnetic material of the opening seal perimeter place of valve body 1; Two valve blocks 2 of magnetic or ferromagnetic material are rotatably connected on the valve body 1 by the little axle of both sides; Below 2 rotating shafts of two valve blocks underbeam 5 is set, underbeam 5 upper ends are provided with groove, are filled with flexible materials 4 such as asbestos, sponge, crudefiber crop in the groove, with the gap sealing between two valve blocks.
See Fig. 3, embodiment's 2 concrete structures are as follows: flexible sheet materials 6 such as bonding leather, plastics, fabric between 2 rotating shafts of two valve blocks, and with the gap sealing between the two valve block rotating shafts.Other structure is with embodiment 1.
See Fig. 4,5, embodiment's 3 concrete structures are as follows: little axle is not established in the both sides of two valve blocks 2, flexible sheet materials 6 such as bonding leather, plastics, fabric between 2 rotating shafts of two valve blocks, upper and lower affixed pressure beam 7 of difference and underbeam 5 at flexible sheet material 6, two beams are clamped flexible sheet material 6, make two valve blocks can be closed or open.
