Wind-proof adjustable roof ventilator It is a combination of ("Ventilated Skylight" 05J621-3 and "Electric Lighting and Smoke Exhaust Skylight" 09J621-2). Based on the fixed shelter of the product, the adjustable wind shelter capacity is added to cope with the short-term extreme climate change in the region, ensuring long-term stability. Fixed wind and ventilation capacity; the product forms a light-transmitting scattering angle through the combination of the damper plate and the flashing to ensure the natural light-harvesting effect of the building; thus, the ventilation and lighting technology products for the building roof differentiation are comprehensively developed into the sheltered lighting and ventilation. Integrated technology products, products authorized national invention patents.
        The wind-proof adjustable roof ventilator improves the comprehensive application capacity of the building energy-saving, especially for buildings with large spans and deep depths, and uses the roof to increase the natural ventilation and lighting effects to reduce the building energy consumption.
        The product structure includes: structural skeleton, flashing, gutter, windshield, damper plate, sump, opening and closing device, electrical configuration, etc.

Product technical characteristics

        1、Control the free opening and improve the wind avoidance ability. Set the damper plate at the ventilating vent of the ventilator, adjust the opening degree of the ventilator according to the external environmental climate change to adjust the wind avoiding ability of the ventilator; adjust the opening of the damper plate according to the ventilation demand in the building. Control the ventilation flow in the building; set the sump at the ventilator drain, seal the bottom drain, and adopt organized drainage to prevent the ventilator from polluting the building surface.

        2、Increase the ventilation capacity, adjust the wind load by the adjustable performance of the valve plate. On sunny days, the exhaust vent can be opened to a larger extent, the exhaust area is increased, and the ventilation capacity is improved. Extreme weather closure of the damper plate reduces overall height, reduces wind loads, and reduces wind damage. The type of the mid-suspension valve plate is reduced in height, does not reduce the exhaust area, and has small opening and closing torque.

        3、The lighting function of the product is increased. The sunscreen panel is used for the air damper plate. The lighting area of ​​the product is increased by more than 30%. The lighting valve plate at the roof vent is removed, the light transmittance is enhanced, and the lighting function failure does not occur.

        4、The rigor is strengthened, and the application range of the product is expanded. The anti-mosquito net can be installed at the through-flow port, and the structural joints can adopt the necessary sealing measures, and can be applied to the lighting and ventilation of civil residential buildings and public buildings with high requirements for strictness.

        5、The mechanical performance of the product is improved, and the screw rod connecting rod valve plate opening and closing device is improved, and the mechanical performance of the product is comprehensively improved. The opening and closing device has long transmission distance, large load, stable transmission and good synchronism, and is convenient for opening and closing and opening of the damper plate. Degree limit control for easy maintenance.

        6、Improve the safety of the product "valve plate opening and closing device" has improved the mechanical control ability of the product, which is more convenient for installation and maintenance, and the safety of personnel operation has been greatly improved.

Product structure and reference data sheet

Product design selection reference

1、The structural dimensions of the listed specifications are conventional standard designs.

2、Standard design choice: wind load 1200Pa, snow load 0.5KN/m2, seismic intensity ≤ 7 degrees

3、Roof vent specifications <1500mm, roof vent specifications > 6000MM, refer to thin roof ventilators.

4、Product insulation and anti-condensation need to take thermal insulation measures for the enclosing material, which has a great impact on product cost. Consider the technical and economic specifications of the product should not exceed 3000mm. The roof roof ventilator or the corresponding technology of "Ventilated Skylight" (05J621-3) can be selected according to the rigor of the building.

5、The utility model patent "valve plate opening and closing device" is the rigid drive of the connecting rod, and the power mechanism is two forms of motor reducer and electric push rod.
a. The motor deceleration power is divided into 1.1KW and 0.55KW. The amount of ventilator is 18m and 24m according to the standard side opening and suspension of the valve plate.
b. The electric push rod is a safe voltage, generally 24V, and the opening and closing control ventilator is 12 meters and 18 meters.
c. The electric deceleration mechanism needs to be equipped with a pedestal with an auxiliary maintenance platform; the electric push rod method does not require a pedestal, and the design overhaul platform can be selected according to maintenance needs.
d. Since the remote control cannot observe the opening and closing of the device, the motorized speed reduction mechanism must be equipped with over-limit protection to prevent the electronic control limit from malfunctioning.

6、Electrical facilities
a. The supporting electric control box of the production plant, each electric control box is generally set with 3-4 control loops, that is, supporting 3-4 sets of opening and closing devices.
b. From the electric control box to the equipment motor supporting cable (line), the cable tube (frame) has design and contractual agreement to be supplied or installed by the production factory (with installation requirements), no design and contract agreement, the production plant is responsible for the motor to the equipment. Terminal box part supply or installation

7、Ventilation foundation flooding board (see basic flooding enlargement diagram): There are design and contract requirements for the ventilator manufacturer to supply or install the ventilator flooding together with the basic flooding; no design and contract requirements should be provided by the roofing construction unit According to the roof panel type and the basic relationship, the manufacturer is responsible for the supply and installation of the ventilator to the basic part of the floodplain.
