The smoke exhaust valve is a high -quality smoke and fire fire valve, which has super strong performance. We can see that during the entire use process, but we must make full use of its super performance. First of all, everyone must successfully install smoke exhaust fire and fire fire fire prevention fire.valve.How much do you master the key common problems in the installation of smoke and fire valve?
The oil circuit board of the smoke discharge fire valve should be raised separately to prevent the deformation of the pipeline prevent the opening and closing of the gate valve.On one side of the actual operating agency of the gate valve and the other side of the porn mechanism, there should be a net interior space of not less than 200mm for maintenance.
The oil circuit board can be installed vertically or horizontally, and the leaves installed must be parallel to the road.The smoke -proof fire prevention valve is installed on the valve top. The actual operator should set up a hand hole, and the specifications should not be less than 450*450mm.
When the wheels are wrapped around the operator, the cable should not be lower than 3 laps, and the cable joint should be stuck.When installing the controller, the installation box should be placed by the wall.The specifications of the installation box should be determined according to the size of the remote control operator.The outer layer of the connection pipe between the smoke and fire valve and the server firewall should have refractory and thermal insulation materials and thermal insulation plates. The home appliance line should have φ20mm of fire -resistant and insulation material maintenance tube.
For mechanical supercharged exhaust system software, a 70 ° C fuse and exhaust fire prevention valve can be set on the intake pipeline of the supercharged fan to avoid the new air system channels being threatened by fire accidents and smoke, and smoke to the building.The imported director of the fire exhaust fan shall install the exhaust fire prevention valve.When the exhaust system temperature exceeds 280 ° C, it can be automatically closed and locks with the fire exhaust fan.When the exhaust fire prevention valve is closed, the centrifugal fan stops.
Tobacco fire prevention valves shall work continuously for 30 minutes at 280 ° C standard.It must be noted that the smoke and fire prevention valve is set on the front and back of the smoke exhaust fan, and it should be flexible and clear according to the specific situation.Take the villa basement exhaust system as an example.When there is only one floor of the basement of the villa, when the smoke exhaust system is discharged into the outdoor area according to the vertical ventilation duct, the fire valve of the smoke exhaust system should be installed on the importer of the smoke exhaust fan.
When the total number of wooden floors in the basement of the villa is above the second floor, the smoke discharge system well on each floor should be distributed on the key entry and exit of fire fire exhaust fan on each floor.Essence
