Embodiment 1

[0028] refer to figure 1 , a method for detecting smoke insulation performance of an exhaust duct, comprising the steps of:

[0029] S01) connecting the smoke generator 1, the first smoke exhaust pipe 2, the fan 3, the second smoke exhaust pipe 4 and the building exhaust duct in sequence;

[0030] S02) Start the smoke generator 1 and the fan 3, the fan 3 sucks the smoke generated by the smoke generator 1 through the first smoke exhaust pipe 2, and blows the smoke into the building exhaust duct through the second smoke exhaust pipe 4.

[0031] It should be noted that: when the smoke generator 1, the first smoke exhaust pipe 2, the fan 3 and the second smoke exhaust pipe 4 are connected in sequence, the four are assembled into a movable detection device to realize the detection of the exhaust duct of the building. Smoke performance.

[0032] refer to figure 1 , the building exhaust duct in this embodiment has a smoke flow channel 61 and an exhaust port 611 communicating with ...

Embodiment 2

[0054] A method for detecting smoke insulation performance of an exhaust duct, comprising the steps of:

[0055] S01) connecting the smoke generator, the first smoke exhaust pipe, the fan, the second smoke exhaust pipe and the building exhaust duct in sequence;

[0056] S02) Start the smoke generator and the fan, the fan sucks the smoke generated by the smoke generator through the first smoke exhaust pipe, and blows the smoke into the building exhaust duct through the second smoke exhaust pipe.

[0057] In this embodiment, the smoke generator includes a smoke generator body, which is provided with a smoke outlet for discharging smoke; the first smoke exhaust pipe is provided with a first smoke exhaust channel, and the first smoke exhaust channel is There is a first smoke inlet and a first smoke exhaust port; a smoking channel is provided on the fan, and a third smoke inlet and a third smoke exhaust port are provided on the smoking channel; a second smoke exhaust port is provid...

Embodiment 3

[0061] refer to figure 2 , a method for detecting smoke insulation performance of an exhaust duct, comprising the steps of:

[0062] S01) connecting the smoke generator 1, the blower fan 3, the smoke exhaust pipe 4 and the building exhaust duct sequentially;

[0063] S02) Start the smoke generator 1 and the fan 3, the fan 3 sucks the smoke generated by the smoke generator 1, and blows the smoke into the exhaust duct of the building through the smoke exhaust pipe 4.

[0064] It should be noted that when the smoke generator 1, fan 3 and smoke exhaust pipe 4 are connected in sequence, the three are assembled into a movable detection device to realize the detection of the smoke insulation performance of the building exhaust duct.

[0065] refer to figure 2 , the building exhaust duct in this embodiment has a smoke flow channel 61 and an exhaust port 611 communicating with the smoke flow channel 61. Since the exhaust duct is installed on the building, when the smoke in the buil...

Abstract

The invention relates to a detection method for smoke isolation performance of an exhaust duct. By adoption of the detection method, the problem that exhaust duct smoke isolation performance detection methods are not good enough is solved. The detection method for the smoke isolation performance of the exhaust duct comprises the following steps that (S01) a smoke generator, a first smoke exhaust pipeline, a fan, a second smoke exhaust pipeline and the building exhaust duct sequentially communicate to one another; and (S02) the smoke generator and the fan are started, and the fan sucks smoke generated by the smoke generator through the first smoke exhaust pipeline and blows the smoke into the building exhaust duct through the second smoke exhaust pipeline.

Description

technical field [0001] The invention relates to a detection method for the smoke insulation performance of an exhaust duct. Background technique [0002] The fire check valve includes a valve body and a valve plate connected to the valve body. The valve body is provided with a valve port, and the valve plate is used to open or close the valve port. The residential building is equipped with an exhaust duct, and there are multiple installation ports on the exhaust duct. The fire check valve is installed on the installation port and closes the installation port. When the valve plate opens the valve port, the smoke in the residence can pass through the valve port. Move into the exhaust duct; when the valve plate closes the valve port, the smoke in the exhaust duct will not be able to move into the house. [0003] Before the existing residential buildings are delivered to users, the smoke insulation performance of the exhaust duct needs to be tested, which includes the following...
