The ventilation and smoke discharge of the smoke vents of the factory building is a technical parameter to measure the overall effect of smoke ventilator, and the throat is one of the influencing factor. Different types of ventilation skylights have corresponding throat sizes. Then, the Mcwell will analyze the influence of the throat size of the factory skylights on the ventilation and smoke exhaust effect.

1. Classification of plant skylights

According to the classification, the smoke vents are mainly divided into roof louver vent, streamlined natural ventilator and electric lighting and smoke exhaust ventilator. The streamlined natural ventilator can be divided into small throat streamlined ventilators and large throat streamlined ventilators according to the throat size, small throat Streamlined ventilators are mainly type 6 ventilators (integral skeleton type) and type 7 ventilators (box-shaped skeleton type), and streamlined ventilators with large throat are type 4 ventilators (pressure rod type) and type 5 ventilators ( Concealed button).

2. The size of the throat of the smoke ventilator in the workshop

The size of the throat of the power sunroof in the workshop is 1500-9000mm, and the formed ventilation and smoke exhaust volume is large, there is no dead corner area, and the ventilation and smoke exhaust efficiency is high. It can realize the ventilation and smoke exhaust required by the workshop and is widely used. It is used in high temperature, high heat, chemical and other factories.

3. The specific application of thin ventilation and smoke exhaust ventilator

Thin ventilation and smoke exhaust skylight is a type of skylight widely used in factory skylights. Because the overall height of the thin ventilation and smoke exhaust skylight is low, the weight is light, and the load is small, it can reduce the steel consumption in the production process and is more economical. Ventilation and smoke exhaust skylights. In addition, the thin ventilation and smoke exhaust skylight adopts modular installation, which can realize rapid commissioning and create economic value for workshops and workshops.
