Technical field
The utility model belongs to a kind of industrial premises roof natural ventilation equipment, particularly a kind of formula closed roof ventilator.
Background technology
The large scale industry power house ventilation all extensively adopts the roof ventilator of gravity-flow ventilation at present.The prior roofs ventilator generally is by the support 1 that is installed in corresponding aditus laryngis place on the roof 7, be located at the weather shield 2 above the support 1, be located at the outer casing 5 and the flashing plate 6 of support 1 both sides, and the water conservancy diversion valve plate 4 that is located on the support 1 constitutes with the motor mechanism for opening/closing 3 of controlling the folding of water conservancy diversion valve plate.Being exhaust outlet 8 between described outer casing 5 and the weather shield 2, is discharge outlet 9 between outer casing 5 and the flashing plate 6, as shown in Figure 1.This roof ventilator is simple in structure, ventilation effect good, but the tightness of structure is relatively poor, there is following problem when using: after 1, closing the water conservancy diversion valve plate as insulation in the winter time, the Shi Xuehui that the snows ventilator that racks is inner and fall on the water conservancy diversion valve plate, in case open water conservancy diversion valve plate or snow melting, accumulated snow or melt after water just can inlet chamber in, pollute the environment in the factory building; 2, in other season, upper surface just can be piled up a large amount of dusts but can't clean after the water conservancy diversion valve plate is closed a period of time, and light transmittance is constantly reduced, and influences indoor lighting; 3, when the water conservancy diversion valve plate is opened, snow and sand and dust descend and can enter ventilator and indoor by discharge outlet in the wind-force effect, and environment in the factory building and equipment are polluted.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of good sealing effect, can avoid rain, snow, sand and dust inlet chamber internal contamination environment, light transmittance height, the effective closed roof ventilator of daylighting.
The technical solution of the utility model is as follows: it comprises the support 1 that is installed in corresponding aditus laryngis 10 places on the roof 7, be provided with weather shield 2 on support 1 top, be provided with outer casing 5 and flashing plate 6 in support 1 bilateral symmetry, be exhaust outlet 8 between outer casing 5 and the weather shield 2, be discharge outlet 9 between outer casing 5 and the flashing plate 6, on support 1, be provided with opening-closing control mechanism 3, its special character is: be hinged with the sealing valve plate 11 that exhaust outlet 8 can be closed on the support 1 between outer casing 5 and weather shield 2, the free end of sealing valve plate 11 links to each other with opening-closing control mechanism 3 and realizes the draft switch adjusting, is provided with the water leg 14 with discharge outlet 9 sealings between outer casing 5 and flashing plate 6.
Above-mentioned closed roof ventilator also is provided with the insulation valve plate 16 that links to each other with opening-closing control mechanism 3 above corresponding aditus laryngis 10 on the support 1, to improve sealing effectiveness.
The utility model has the advantages that: 1, owing on support, be provided with the sealing valve plate that exhaust outlet can be closed, between outer casing and flashing plate, be provided with water leg with the discharge outlet sealing, therefore this ventilator inside can form an airtight space when the sealing valve plate is closed, can avoid in the winter time or during bad weather rain, snow, sand and dust enter ventilator inside, help keeping indoor environmental hygiene, just can realize indoor ventilation after the sealing valve plate is opened.2, by sealing valve plate and cancel original water conservancy diversion valve plate is set, can avoid because of the long-pending a large amount of dusts of diaphragm valve sheetpile reduce light transmittance, light transmittance height, daylighting are effective.3, can avoid snow and sand and dust to descend by discharge outlet to enter ventilator and indoor by water leg in the wind-force effect; Rainwater is fed directly in the water leg along weather shield simultaneously, can realize organized draining by water leg, has replaced original free draining, can avoid the pollution of draining to the roof.4, valve board structure reduces convenient switch and regulates, and has greatly reduced switch power, simultaneously reduced the material and the cost of transportation of product, cost performance of product height.5, improved the installation of product and the security of use, the working service of product is convenient.
