SUMMERY OF THE UTILITY MODEL
Aiming at the defects of the prior art, the utility model provides the reducing air pipe centralized joint used in the fire-fighting smoke exhaust system, which can realize centralized discharge of each branch pipe with small flux, save the floor area of a ventilation system and improve the discharge efficiency.
The technical scheme of the utility model is as follows: the reducing air pipe centralized joint used in a fire-fighting smoke discharging system comprises a flange main pipe, an air collecting box and a plurality of branch pipes, wherein the air collecting box is of a trapezoidal structure, the upper bottom area of the air collecting box is smaller than the lower bottom area, and four side surfaces of the air collecting box are hermetically connected with the upper bottom and the lower bottom; the upper bottom of the air collecting box is in through connection with the flange main pipe, the lower bottom of the air collecting box is in through connection with the branch pipes, and the pipe diameter of the flange main pipe is larger than that of the branch pipes.
Furthermore, the lower bottom of the air collection box is connected with four branch pipes, and the four branch pipes are linearly arranged and connected to the lower bottom of the air collection box.
Further, the pipe diameters of the four branch pipes are equal and are all 35 cm.
Further, the pipe diameter of the flange main pipe is 70 cm.
Furthermore, the end part of the flange main pipe is fixedly connected with a flange plate, and a plurality of connecting holes are formed in the flange plate.
Furthermore, the flange main pipe and the air collecting box are connected in a welding mode, and the air collecting box and the branch pipes are also connected in a welding mode.
Furthermore, the flange main pipe, the air collecting box and the branch pipes are all made of stainless steel materials.
Compared with the prior art, the utility model has the beneficial effects that: the air pipe centralized joint comprises a plurality of branch pipes and a main pipe, wherein the branch pipes are connected to different discharge spaces, and gas in different minutes is collected in the air collecting box and then discharged through the flange main pipe, so that the problems that the space occupied by the branch pipes is large when the branch pipes are independently discharged, and the mutual interference among all pipelines is low are effectively solved; the air collecting box also has the function of mixing air with different flow rates flowing in through the branch pipes, and the mixed air is discharged through the flange main pipe to enable the air flow rate in the pipes to be more balanced.

Detailed Description
The utility model is further described below with reference to the figures and examples.
As shown in fig. 1-2, the reducing air duct centralized joint for a fire-fighting smoke exhaust system of the present invention comprises a flange main pipe 1, an air collecting box 2 and a plurality of branch pipes 3, wherein the air collecting box 2 is of a trapezoidal structure, the upper bottom area of the air collecting box 2 is smaller than the lower bottom area, and four side surfaces of the air collecting box 2 are hermetically connected with the upper bottom and the lower bottom.
The number of the branch pipes 3 is preferably four, the four branch pipes 3 are linearly arranged and connected to the lower bottom of the air collection box 2, the branch pipes are communicated with the lower bottom of the air collection box 2, and the flange main pipe 1 is communicated with the upper bottom of the air collection box 2.
The pipe diameter of flange house steward 1 is greater than the pipe diameter of being in charge of 3, and is concrete, four pipe diameters that are in charge of 3 equal, are 35cm, and the pipe diameter of flange house steward 1 is 70cm, and the tip fixedly connected with ring flange 11 of flange house steward 1 has seted up a plurality of connecting holes on the ring flange 11.
Furthermore, the flange main pipe 1 and the air collecting box 2 are connected in a welding mode, and the air collecting box 2 and the branch pipe 3 are also connected in a welding mode.
When the exhaust gas is exhausted, the tail ends of different branch pipes 3 are communicated with different spaces, the four branch pipes 3 can run simultaneously and can also independently supply air, the gas is exhausted from the flange main pipe 1 after being collected in the air collecting box 2, and the air collecting box 2 can mix and adjust the air with different flow rates, so that the flow rates of the air flow entering the flange main pipe 1 are balanced, and the exhaust effect can be prevented from being influenced by the disorder of the gas; the centrally-arranged flange main pipe 1 occupies a small space, and can avoid the problems of disordered appearance and low air exhaust efficiency caused by mutual interference when a plurality of small flux branch pipes 3 are arranged.
