Abstract
The utility model relates to a valve of an exhaust duct of a building, which is installed at the air inlet opening of the exhaust duct. The valve comprises a valve body and is characterized in that a connector communicated with a hose of a kitchen ventilator is arranged at one end of the valve body, an air outlet opening is formed at the other end of the valve body and is inclined outwards from up to down, a valve plate for sealing the air outlet opening is installed at the upper part of the air outlet opening through a bearing, a wind shielding plate is vertically fixed at the lower part of the air outlet opening and in front of the valve plate, an external valve plate for sealing the air outlet opening is also installed at the upper part of the air outlet opening through a bearing, and the external valve plate is positioned on the outer side of the wind shielding plate. The utility model has the advantage that the valve has simple structure, is economic and practical and can effectively play the role of avoiding the phenomenon of back flow.
Description
Technical field:
The utility model relates to a kind of building exhast duct valve that is installed in exhast duct air intake place.
Background technology:
The existing valve that in exhast duct, uses, because of after long-term use causes the valve blade to adhere to a large amount of dusts easily, cause close between valve blade and the valve body close not tight, thereby do not have sealing process, cause the generation of pouring in down a chimney phenomenon at last.
Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of can playing effectively to prevent to pour in down a chimney the building exhast duct valve that phenomenon takes place.
The technical solution of the utility model is: comprise valve body, it is characterized in that: valve body one end is the interface that is connected with the smoke exhaust ventilator flexible pipe, the valve body other end is an air outlet, this air outlet is from the top down toward the air outlet of outer incline, by bearing the valve block of sealing this air outlet is installed on this air outlet top, vertically is fixed with a verge board in the bottom of air outlet, the place ahead of valve block.
By bearing the outside valve block of sealing this air outlet is installed also on this air outlet top, outside valve block is positioned at the outside of verge board.
The utlity model has simple in structure, economical and practical, can play and effectively prevent to pour in down a chimney the advantage that phenomenon takes place.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
As shown in Figure 1, the utility model comprises valve body 1, it is characterized in that: valve body 1 one ends are the interface 2 that is connected with the smoke exhaust ventilator flexible pipe, valve body 1 other end is an air outlet 3, this air outlet 3 is from the top down toward the air outlet of outer incline, by bearing the valve block 4 of sealing this air outlet 3 is installed on these air outlet 3 tops, vertically is fixed with a verge board 6 in the bottom of air outlet 3, the place ahead of valve block 4.
By bearing the outside valve block 5 of sealing this air outlet 3 is installed also on these air outlet 3 tops, outside valve block 5 is positioned at the outside of verge board 6.
