Abstract

The invention discloses a smoke and odor channeling prevention flue. The smoke and odor channeling prevention flue comprises a main air flue, an exhaust pipe, a check valve and a sealing board, wherein a through hole is formed in the wall of the main air flue; the exhaust pipe is installed in the through hole; the check valve is installed in the exhaust pipe; the check valve comprises a valve block and a valve block shaft; a valve block hole is formed in the valve block; the valve block shaft penetrates through the valve block hole to be installed in the exhaust pipe; a protrusive blocking piece is arranged on the inner wall of the exhaust pipe; a sealing board is arranged at the end, close to the main air flue, of the exhaust pipe; the sealing board is connected with the top of the exhaust pipe through a hinge structure; an installation hole of the valve block of the check valve is installed in the middle of the valve block, so that the whole valve block is opened conveniently, and smoke is drained smoothly; meanwhile, the sealing board is arranged at the end, close to the main air flue, of the exhaust pipe, and can prevent smoke drained from other residents from flowing backwards, and the smoke and odor channeling prevention effect is greatly improved. Meanwhile, the smoke and odor channeling prevention flue has the advantages of being simple in structure, convenient to install and maintain, and the like.

Description

A kind of preventing smoke-channeling anti-crossing smell flue
Technical field
The present invention relates to a kind of building unit, particularly relate to a kind of preventing smoke-channeling anti-crossing smell flue.
Background technology
The useless cigarette great majority that existing multilayer and high-rise residential building produce adopt the common flue discharge of resident family, the opening of every family to common flue is open type in the early stage, when all users be not discharge fume simultaneously time, pressure in main air duct is greater than the pressure of branch air duct, cause flue gas adverse current to pour in down a chimney, bring very big inconvenience to resident family's life.Existing flue adopts valve block pressure swing type structure mostly, this structure is when discharging fume, because valve block tilts to have an angle, and the installation shaft of valve block is arranged on middle and upper part, can not open completely at the effect lower disc of useless flue gas, flue dust makes flue dust not easily discharge smoothly when air channel is outwards discharged by the stop of valve block, transformation poor performance, but when resident family oneself does not have smoke discharging, and other resident family is when smoke discharging, the flue gas of other resident family can pour in down a chimney by non retern valve, i.e. preventing smoke-channeling weak effect.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, and provide a kind of smoke discharging smooth, the preventing smoke-channeling anti-crossing smell flue that preventing smoke-channeling is effective.
Technical scheme of the present invention is: a kind of preventing smoke-channeling anti-crossing smell flue, it comprises main air duct, exhaust duct, non retern valve and sealing plate, main air duct wall has through hole, exhaust duct is installed in through-holes, non retern valve is arranged in exhaust duct, non retern valve comprises valve block and valve shaft, valve block is provided with valve block hole, valve shaft is arranged in exhaust duct through valve block hole, exhaust duct inwall is provided with protruding barrier sheet, it is characterized in that: exhaust duct is provided with sealing plate near main air duct one end, sealing plate is connected by hinge arrangement with the top of exhaust duct.
The further technical scheme of the present invention is: described valve block hole is located at the middle part of valve block, and valve shaft is arranged on the middle part of exhaust duct.
The further technical scheme of the present invention is: described exhaust duct inwall is also provided with limited block.
The further technical scheme of the present invention is: described main air duct is made up of glass fiber and refinforced cement.
The further technical scheme of the present invention is: described exhaust duct is more outstanding than top near the bottom of main air duct end.
The invention has the beneficial effects as follows: the present invention improves owing to adopting above structure, the installing hole of the valve block of non retern valve is located at the middle part of valve block, be conducive to valve block all to open, smooth discharge flue gas, be provided with sealing plate at exhaust duct near one end of main air duct, the flue gas that can prevent other resident families from discharging pours in down a chimney comes in simultaneously, significantly improves the effect of preventing smoke-channeling anti-crossing smell, structure of the present invention is simple simultaneously, convenient for installation and maintenance.

Detailed description of the invention
Below in conjunction with figure and detailed description of the invention, detailed construction of the present invention is further described.
As shown in Figure 1: a kind of preventing smoke-channeling anti-crossing smell flue, it comprises main air duct 1, exhaust duct 4, non retern valve and sealing plate 3, main air duct 1 wall has through hole, exhaust duct 4 is installed in through-holes, non retern valve is arranged in exhaust duct 4, non retern valve comprises valve block 21 and valve shaft 22, valve block 21 is provided with valve block hole, valve shaft 22 is arranged in exhaust duct 4 through valve block hole, exhaust duct 4 inwall is provided with protruding barrier sheet 23, exhaust duct 4 is provided with sealing plate 3 near main air duct 1 one end, and sealing plate 3 is connected by hinge arrangement 31 with the top of exhaust duct 4.
Described valve block hole is located at the middle part of valve block 21, and valve shaft 22 is arranged on the middle part of exhaust duct 4.
Described exhaust duct 4 inwall is also provided with limited block 32.
Described main air duct 1 is made up of glass fiber 11 and refinforced cement.
Described exhaust duct 4 is more outstanding than top near the bottom of main air duct 1 end.
Operating principle of the present invention is: during work, the useless flue gas of resident family's discharge is outwards discharged by stack 4, useless flue gas promotes valve block 21 and rotates certain angle by valve block hole around valve shaft 22, because valve shaft 22 is arranged on the middle part of stack 4, so whole valve block can all be opened, smooth promotion sealing plate 3 rotates around hinge arrangement, and the flue gas that will give up is all discharged to main air duct.When flue gas is given up in exhaust duct 4 not air draft, sealing plate 3 covers exhaust duct 4 completely, the useless flue gas of other resident family discharge does not enter in the family of resident family by exhaust duct, can only be emitted by main air duct, resident family is played to the effect of good preventing smoke-channeling anti-crossing smell, structure of the present invention is simple simultaneously, convenient for installation and maintenance.
More than show and describe general principle of the present invention and principal character; the technology people of the industry states embodiment and does not limit the present invention in any form; the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, all drops in protection scope of the present invention.
