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

A kind of flue gas exhaust pipeline

Technical field

The present invention relates to a kind of flue gas exhaust pipeline, specifically a kind of band helps the smoke discharging pipe of arranging device.

Background technology

Present all kinds of dwelling houses all use common exhaust duct, and each resident family enters indoor flue gas trunk line, concentrates from the exit on roof and discharge by the air inlet on the trunk line, yet the flue gas of lower floor is in last row's process, meeting enters in the room from the air inlet of the resident family on upper strata, when wind is big, the flue gas that the discharge of upper strata resident family also can occur turns back to the indoor phenomenon of resident family of lower floor, gives and uses the resident family in district to bring inconvenience.

At present, those skilled in the art seek various solutions always, wherein patent ZL01136512.9 discloses a kind of pressure variable exhausting channel, it has added variable-pressure plate in smoke discharging pipe, and at trunk line interpolation guide pipe, exhaust check valves etc. solve above-mentioned problem, the structure more complicated, manufacturing cost is than higher, and all elements all are fixed on the trunk line with screw etc., an element or several element are loosening to drop if having, and will certainly influence the use of the discharge duct below it so, and installs and all very inconvenience of maintenance, increased the labour intensity and the difficulty of installation or service worker, be unfavorable for the application of this pipeline and popularize.

Summary of the invention

The purpose of this invention is to provide a kind of smoke discharging pipe that makes things convenient for I﹠M.

For achieving the above object, the present invention is by the following technical solutions:

A kind of flue gas exhaust pipeline of the present invention, comprise the flue gas exhaust pipeline body, at least be provided with an air inlet on the flue gas exhaust pipeline body, each air inlet place is provided with and helps comb, help comb to be positioned at the inside of pipeline body, described comb and the pipeline body of helping is structure as a whole, and helps one section lower end closed of comb and pipeline body inwall formation and the diameter flue that goes out less than the pipeline body internal diameter.

As a kind of improvement, the air inlet place of described pipeline body is equipped with the smoke evacuation check valve.

Among the present invention, described smoke discharging pipe, by helping comb and smoke discharging pipe to be structure as a whole, thereby when having saved pipe laying, this procedure that helps comb is installed separately again, simultaneously also having prevented to help problems such as comb drops because of bolt etc. is loosening, helped comb and the smoke discharging pipe process from split to an integral body, is through ruminating over and repeatedly testing the conclusion that draws, be not conspicuous in the art, so have the high-lighting characteristics, improve by this, reduced workman's installation and repair density, and it is simple in structure, production cost is low, is easy to be extended and applied, and has tangible progress.

The specific embodiment

The invention will be further described below in conjunction with the drawings and specific embodiments.

As shown in Figure 1, a kind of flue gas exhaust pipeline, comprise flue gas exhaust pipeline body 1, at least be provided with an air inlet 4 on the flue gas exhaust pipeline body 1, each air inlet 4 place is provided with and helps comb 2, help comb 2 to be positioned at the inside of pipeline body 1, described comb 2 and the pipeline body 1 of helping is structure as a whole, help comb 2 and pipeline body 1 inwall to form one section flue that goes out less than lower end closed and diameter pipeline body 1 internal diameter, promptly help comb 2 and pipeline body 1 one-shot forming in same mould, promptly when casting, in casting mould, add the structure that a casting helps comb 2, make after casting is finished, help comb 2 and smoke discharging pipe 1 to become one.

In casting process, air inlet 4 can be reserved, also can need drive gas port 4 places at flue gas exhaust pipeline body 1 does underlined, when pipe laying, utilize modes such as cutting again, in mark air inlet 4 is carried out, whether the reservation of air inlet 4, is to decide according to the characteristics and the needs of flue gas exhaust pipeline body 1 self.

As Fig. 2, Fig. 3 and shown in Figure 4, in order to be convenient to install check valve 3 at air inlet 4 places, the described cross section that helps the smoke pipeline that comb 2 and pipeline body 1 form is set to semicircle, square, triangle or semicirclely combines with square, can be according to the requirement such as unobstructed of needs of making and exhaust, the shape of cross-sectional area is set, for another example half elliptic, trapezoidal etc.

As shown in Figure 5, flue gas exhaust pipeline body 1 may be provided with two air inlets 4 of symmetry on sustained height, and two air inlet 4 places help comb 2 by one, certainly air inlet 4 also may be three or more, perhaps the position of air inlet 4 is asymmetric, but flue gas exhaust pipeline body 1 with help comb 2 all to be structure as a whole.

As shown in Figure 6, the installing port place of described pipeline body 1 is equipped with smoke evacuation check valve 3, prevents that when wind was big, cigarette was backed indoor.

The material of whole smoke discharging pipe is that cement, glass fiber screen cloth or wire netting etc. mix by a certain percentage, can reduce cost like this, and when smoke discharging pipe time spent not, can waste material yet, be easy to be extended and applied.
