The use of steel roof ridge vent is mainly driven by the natural wind outside the child labor. Negative pressure is formed inside the ridge ventilator, and indoor hot air is exhausted to the outside through the openings in the factory building to promote the circulation of indoor air. In the design specification of industrial ridge vent, Mcwell, as a professional smoke vents manufacturer, has its own set of design requirements standards.
1. The design, manufacture and installation of steel roof ridge vent ensure safe, reliable and continuous operation under the allowable use conditions of the equipment.
2. The structural layout of the ridge ventilator is reasonable, the air flow is unobstructed, there is no obvious dead angle area for ventilation, and the flow resistance is small; the windshield layout is reasonable, has a good wind shelter effect, and can effectively prevent outdoor air backflow; and has a reliable measures to prevent rain and snow from penetrating, to ensure that the smoke vent rooflight does not penetrate the room under any weather conditions, and to ensure the normal use of the smoke vent system.
3. The main body of the ridge ventilator is firm, safe and reliable. It can withstand the local wind load and snow load, and does not affect the normal use of the roof ventilation skylight. At the same time, it meets the relevant local seismic regulations.
4. The valve plate of the industrial ridge vent has good airtightness and small air leakage. When the valve plate is fully closed in winter, the air leakage is not more than 0.01% of the fully open state in summer to ensure the quality of indoor heating in winter and save energy. The valve plate adopts heat preservation measures to prevent condensation, and has a good method of draining condensate.
5. The ventilating skylight valve plate and its transmission mechanism are flexible and reliable in operation.
6. In order to check the valve plate, a manhole is set on the guard plate at the valve plate operating mechanism. The manhole door is flexible to open and close, and uses hinged connection to prevent rain, snow, and water leakage.
7. The metal building ridge vents adopt an electric switch mechanism to open and close the valve plate of the roof ventilation skylight. When using an electric switch mechanism, it has the possibility of manually opening and closing the valve plate. The electric control operation panel of the electric mechanism is arranged in a place that is convenient for operation personnel on duty. The electric opening and closing mechanism is reliable, easy to install and easy to maintain. The valve plate motor is arranged on the outer roof of the ventilated skylight to facilitate maintenance and prevent rain, snow and sun.
8. The external surface of the installed ventilation skylight does not exceed the range of the lightning protection device of the building.
9. The design torque of the electric operating device is at least 1.5 times the torque required to open or close the valve plate under the specified air leakage under the maximum design conditions, whichever is the maximum.
