The flue joint forms a rectangular parallelepiped shape; the inside end of the flue joint at a vertical direction is provided with square flue holes, and the upper side and the lower part of the outer ends of the flue joint are respectively provided with a chimney hole and a removing ash hole which are vertically connected with flue holes; the flue is composed of two or more flue pipes whose both ends are connected with each other; the flue pipes are of square long pipes with both ends opening; the lower ends of the flue pipes are of flat openings and the upper ends of the flue pipes are of square openings which are connected with the lower end flat opening of the previous flue pipe. The utility model has the advantages of convenient and reliable installation and strict interfaces and can prevent flow crossing effectively, being suitable for civil residences to work as a discharge flue as well as a wind channel.

Description

Discharge flue capable of preventing crossed flow

The utility model relates to a kind of smoke vent that is installed in the civil house wall.

The smoke vent of residential houses mostly is to be formed by connecting by the above flue pipe of two joints at present, is installed in the body of wall of residential houses, and flue pipe then is that the pea gravel concreten that employing is a skeleton with cold drawn wire or the stubborn flower of thin wire is made.Because the restriction of manufacturing process and template, flue terminal with body of wall be connected and flue pipe between the connection employing of having to flush counterpart.The outstanding shortcoming of this interface mode is the interface imprecision, when being isobaric inside and outside smoke vent, flue gas is very easily revealed (being smoke blowing) from interface, and pernicious gas wherein (as carbon monoxide) very likely endangers the health of human body in the room, even jeopardizes people's life.

The purpose of this utility model is the smoke vent that a kind of easy installation and reliable, interface of design is tight, can prevent smoke blowing effectively.

To achieve these goals, the utility model adopts a kind of monolithic devices and has the flue joint that connects the rim of the mouth and connects body of wall interior flue and Indoor Combustion stove chimney, leaks from flue lower end and body of wall junction to prevent flue gas; Meanwhile, flue pipe is made square, and changed flue pipe and flush, from the seam of flue pipe, reveal to prevent flue gas to the rim of the mouth connects.Be described in further detail below in conjunction with the technical characterictic of specific embodiment the anti-smoke blowing smoke vent of the utility model.

Accompanying drawing 1 is the structural representation of flue joint;

Accompanying drawing 2 is for having the structural representation of the flue pipe that connects the rim of the mouth.

The anti-smoke blowing smoke vent of the utility model is made up of flue and the flue joint that is connected flue and Indoor Combustion stove chimney, and flue is by above end to end the forming of flue pipe of two joints.With reference to the accompanying drawings 1, flue joint 1 assembles in body of wall for cuboid gives the system building block.The inner end vertical direction of building block has the square flue hole 2 identical with hole size in the flue pipe, the floss hole lower end closed, the upper end open place have with flue pipe under hold a mouth square rim of the mouth 3 of matching level with both hands; The rim of the mouth is made and is embedded in by steel sheet on the inwall of floss hole upper end, and the rim of the mouth height should be more than or equal to 10mm, and thickness is 0.75-1.5mm.The upper and lower, outer end of building block has and floss hole 2 vertical circular chimney hole 4 and the square ash drawing holes 5 that also are communicated with, and going to the bottom of ash drawing hole 5 is fair with going to the bottom of floss hole 2.With reference to the accompanying drawings 2, flue pipe 6 is the square long tube of both ends open, and its lower end is flat mouthful, the upper end then have with a last joint flue pipe under hold the square rim of the mouth 7 that mouth matches level with both hands; The rim of the mouth is made and is embedded in by steel sheet on the inwall of flue pipe upper end, and the rim of the mouth height should be more than or equal to 10mm, and thickness is 0.75-1.5mm.

The utility model is easy for installation, reliable, and interface is tight, can effectively prevent smoke blowing, except the smokejack that can be widely used as the residential houses, also can be used as the air channel of residential houses.
