Smoke discharging pipeline

Abstract

The invention discloses a pipeline for removing smoke, comprising a pipeline body which is provided with at least an air inlet, each air inlet is provided with an assisted discharge tube which is arranged inside the pipeline body, a section of smoke vent pipeline with lower end closed and diameter less than the inner diameter of the pipeline body is formed from the assisted discharge tube and the inner wall of the pipeline body; the assisted discharge duct and the pipeline body constitute a united structure, thus saving the process that the assisted discharge tube is additionally arranged when the pipeline is arranged, solving the problem that the assisted discharge tube falls off as bolts are loosened. The process from fission to integration of the assisted discharge tube and the pipeline for removing smoke is the result of repeated trial but is not obvious in the technical field, thus the pipeline for removing smoke is endowed with great features. The pipeline for removing smoke reduces the assembly and maintenance intensity of workers after the improvement, and has simple structure, low production cost and convenient popularization and application, thus making obvious progress.

Description

technical field [0001] The invention relates to a smoke exhaust pipe, in particular to a smoke exhaust pipe with an exhaust aid device. Background technique [0002] Now all kinds of residences use a common exhaust duct, and each household exhausts the indoor flue gas into the main duct through the air inlet on the main duct, and discharges it from the outlet of the roof. During the exhaust process, the smoke from the upper-floor residents will enter the room from the air inlet. When the wind is strong, the smoke from the upper-floor residents will return to the lower-floor residents, which will bring a lot of inconvenience to the residents in the use area. [0003] At present, those skilled in the art have been looking for various solutions, among which the patent ZL01136512.9 discloses a variable pressure exhaust duct, which adds a variable pressure plate in the smoke exhaust duct, and adds a guide tube to the main duct , check exhaust valve, etc. to solve the above probl...

[0002] Now all kinds of residences use a common exhaust duct, and each household exhausts the indoor flue gas into the main duct through the air inlet on the main duct, and discharges it from the outlet of the roof. During the exhaust process, the smoke from the upper-floor residents will enter the room from the air inlet. When the wind is strong, the smoke exhausted by the upper-floor residents will return to the indoors of the lower-floor residents, which will bring a lot of inconvenience to the residents in the use area.

[0003] At present, those skilled in the art have been looking for various solutions, among which the patent ZL01136512.9 discloses a variable pressure exhaust duct, which adds a variable pressure plate in the smoke exhaust duct, and adds a guide tube to the main duct , check exhaust valve, etc. to solve the above problems, the structure is more complicated, the manufacturing cost is relatively high, and all components are fixed on the main pipeline with screws, etc., if one or several components are loose and fall, it is bound to It affects the use of the exhaust pipe below it, and it is very inconvenient to install and maintain, which increases the labor intensity and difficulty of the installation or maintenance workers, which is not conducive to the application and popularization of this pipe
