Description
The utility model relates to the category of kitchen articles, particularly the cross-wall type check valve for flue.
Common culinary lampblack exhauster does not have check valve, and cigarette directly is discharged to outdoor, and smoke-ejecting pipe of each household not only influences the appearance of the city but also befouling environment.
Be the beautifying city, reduce environmental pollution, all there is common flue in modern residential building building.For preventing that cigarette adverse current in the common flue from going into indoorly, so each lampblack exhauster all is furnished with check valve, this check valve can only directly be bumped in the common flue, and smoke exhaust port is opened up.Check valve valve plate fixed flat.This check valve just can't be used in lampblack exhauster or the place that have wall intercept far away from common flue, and its valve plate also can't clean.
The purpose of this utility model is to provide a kind of improved cross-wall type check valve for flue, and it not only can directly be bumped in the common flue, also be applicable to away from common flue or the place that has wall to intercept, and valve plate is convenient to clean.
The purpose of this utility model is achieved in that the smoke outlet of cross-wall type check valve for flue is located at the offside of smoke inlet, and smoke outlet has smoke pipe fitting, is convenient to the spreading smoke pipe and reaches in the common flue, and the place that has wall to intercept also can be assembled smoke pipe by wall.The valve plate of check valve is that formula is inserted on movable way, can extract cleaning out.
The utility model only needs the smoke outlet of flue is located at the offside of smoke inlet, and smoke outlet is provided with the joint of being convenient to the spreading smoke-ejecting pipe.The valve plate of check valve is movable obliquely inserting type, easy enforcement simple in structure.It is Anywhere indoor that this gate-type check valve for flue excessively can make lampblack exhauster be contained in, and check valve also is convenient to clean.
The concrete structure of model utility is provided by following embodiment and accompanying drawing thereof.
Fig. 1 and Fig. 2 are the sectional drawings according to the cross-wall type check valve for flue that the utility model proposes.
Describe details and working condition in detail below in conjunction with Fig. 1 according to the concrete structure that the utility model proposes.
The contrary valve of cross-wall type flue comprises a main body check valve for flue (1), is flue (2) and valve plate (6) in the main body, and the offside of flue entrance (3) is flue outlet (4) and outlet connection (5).
To scheme is example, when valve plate when static (6) separates the work of (see figure 1) lampblack exhauster with the inlet (3) of flue and flue outlet (4), wind-force blows to (see figure 2) with the valve plate (6) of oblique cutting, and inlet of flue (3) and flue outlet (4) communicate, and cigarette is discharged.Because flue outlet (4) is at the offside of flue entrance (3), and is provided with outlet connection (5), can connect smoke pipe (not drawing among the figure), the smoke outlet of the check valve distance that stretches is far away or have in the public flue that wall intercepts.Valve plate is movable oblique plug-in type, is convenient to extract out clean.
Claims (2)
1, have the valve plate (6) of check valve to it is characterized in that the outlet (4) of flue is located at the offside of flue entrance (3) in the cross-wall type check valve for flue (1) of oil extraction machine, flue outlet (4) is provided with smoke pipe fitting (5).
2, cross-wall type check valve for flue according to claim 1 is characterized in that the valve plate (6) of check valve is movable obliquely inserting type.
