Steel structure workshops will generate a lot of smoke, dust and heat during the actual production process. If these industrial wastes are not discharged outdoors in time, it will seriously affect the normal production of the workshops, and even cause safety accidents in serious cases. Therefore, production-oriented industrial plants will install automatic smoke exhaust skylights in the plant to solve this problem.

The main function of the smoke vent is to provide good ventilation, and the ventilation performance is also an important indicator for judging the quality of the smoke ventilator. The ventilation performance is closely related to the throat size design of the ventilation and smoke exhaust skylight.

The effective ventilation area of ​​the fire smoke exhaust ventilation skylight mainly refers to the area of ​​the smallest ventilation section inside the skylight, which is the “throat” in the true sense of the ventilation skylight. Generally speaking, the larger the effective area, the greater the corresponding flow coefficient. Larger, the better the ventilation performance of the ventilation skylight.

If the design of the ventilation and smoke exhaust skylight does not meet the specifications, even if the size of the opening is large, it cannot meet the ventilation and smoke exhaust of the first-line production workshop. If the effective ventilation area does not meet the specified standards, it will seriously affect the smoke exhaust effect of the ventilation skylight It has

become a "ventilated skylight without ventilation", and the business owner has invested a lot of manpower, material resources and energy, which has brought great losses to the production of the factory.
