Abstract

The utility model relates to a smoke discharging pipeline which includes a smoke discharging pipeline body, the smoke discharging pipeline body is equipped with at least one air intake port, each air intake port is equipped with a help discharge pipe, the help discharge pipe locates on an inner part of the pipeline body, the help discharge pipe and the pipeline body are an integrated structure, the help discharge pipe and an inner wall of the pipeline body form a section of smoke discharge pipe which has a closed down part and diameter lesser than an inner diameter of the pipeline body, and is an integrated structure through the help discharge pipe. The integrated structure can omit a work procedure that the help discharge pipe is installed alone when the pipeline is installed, and prevent falling of the help discharge pipe caused by flexible bolt, the process from spit type to integrated structure of the help discharge pipe and the smoke discharge pipeline, is a conclusion obtained by consider repeated and multi-experiment which is not obvious in the prior technical field and has salience characteristic. The improving reduces installation and maintaining strength of labour, and has simple structure and low cost which is convenient for popularizing and application, and has obvious progress.

Description

A kind of flue gas exhaust pipeline

Technical field

The utility model relates to a kind of flue gas exhaust pipeline, and 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 port 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 port 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 extract 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 utility model provides a kind of smoke discharging pipe that makes things convenient for I﹠M.

For achieving the above object, the utility model is by the following technical solutions:

A kind of flue gas exhaust pipeline described in the utility model, comprise the flue gas exhaust pipeline body, at least be provided with an air inlet port on the flue gas exhaust pipeline body, each air inlet port 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 port place of described pipeline body is equipped with the smoke evacuation one way valve.

In the utility model, 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, cost of production is low, is easy to be extended and applied, and has tangible progress.

Fig. 2 be among Fig. 1 A-A to view;

Fig. 3 be among Fig. 1 A-A to the reference diagram of view;

Fig. 4 be among Fig. 1 A-A to the view reference diagram;

Fig. 5 is the reference diagram of the utility model embodiment;

Fig. 6 is user mode figure of the present utility model.

The specific embodiment

The utility model 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 port 4 on the flue gas exhaust pipeline body 1, each air inlet port 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 port 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 port 4 is carried out, whether the reservation of air inlet port 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 one way valve 3 at air inlet port 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 inlet ports 4 of symmetry on sustained height, and two air inlet port 4 places help comb 2 by one, certainly air inlet port 4 also may be three or more, perhaps the position of air inlet port 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 one way 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 gauze 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.
