In the selection of 3C fire prevention valve processing, the height of the circular fire valve is smaller and larger, and the manufacturing is complicated.Therefore, the application is mainly rectangular fire valve.(1) Sending air, including ventilation, such as sending fresh air and exhaust. This scale is wide. For example, the air in the factory workshop, the air out of the place of production, because the harmful gases need to discharge outdoors, and need to transport outdoor air to the room.At this time, the air transport pipes with large flow and small pressure are used. The spiral fire prevention valve is more applicable. Generally, the galvanized iron pipe is used, and the stainless steel pipe is used in corrosive and particularly humid places.(2) Send cool wind.What is more common is the central air -conditioning pipeline, which requires insulation materials for this pipeline.The spiral fireproof valve can be pasted inside the insulation material, which looks beautiful on the surface.(3) exhaust smoke.There are many oil fumes in restaurants, restaurants, and hotel kitchens. Demand discharge. The use of circular fire valve is the oil chimney.Here, the spiral fire valve should be called the oil fume pipe.(4) There are a lot of dust from dust removal and some factories to produce workshops. Demand demand for dust removal equipment, pipelines with large current flow, can be used to use spiral fire prevention valves.
The above is the choice of fire valve, I hope to help you.If you want to know more related issues, please pay more attention to us--
