Abstract
The invention relates to a heat insulation arc ventilator. The ventilator comprises a skeleton structure, rain baffle plates, pulleys, a steel wire rope, a valve plate and a flashing plate, wherein the skeleton structure has an inverted isosceles trapezoid shape, and the chamfer of the upper bottom edge is arc-shaped; the number of the rain baffle plates is two, and the rain baffle plates are arranged in the middle of the skeleton structure; the pulleys are arranged on the lower parts of the rain baffle plates; the steel wire rope is connected on the pulleys; the valve plate is connected with one end of the steel wire rope; and the flashing plate is arranged on the lower part of the skeleton structure. Compared with the prior art, the ventilator has reasonable structure arrangement, low dead weight, good vibration resistance, good corrosion resistance, excellent waterproof performance and long service life, is convenient to install, plays a great role in heat insulation of a factory building, and solves the problem of heat insulation during working in cold regions such as the north and the like and factory building inspection.
Description
Technical field
The present invention relates to a kind of ventilator, especially relate to a kind of thermal-insulating type arcuate ventilator.
Background technology
Two kinds of the ventilation branch machinery ventilation of factory building and gravity-flow ventilations.Force ventilation is to be power drive with force ventilation equipment, air is flowed and ventilates.Gravity-flow ventilation is to utilize the effect of the hot pressing of air and blast and form flowing naturally of air, thereby reaches the purpose of ventilation, need not power, and is pollution-free, environmental protection, energy-conservation.
The principle that the hot pressing of air and blast form:
Hot pressing: after the air in the factory building is heated, volumetric expansion, unit weight diminishes, make the inside and outside air of factory building form gravitational difference, outdoor air just in the bottom inlet chamber of factory building, discharge outdoor from the position of upper opening by indoor air, so circulate, reach the purpose of ventilation.
Blast: when air-flow blows to the wall in house, changed the flow direction of air-flow, the pressure of windward side is increased, produced malleation; The current path of the top in house narrows down, and flow velocity strengthens, and produces negative pressure; The back side of factory building, air-flow forms vortex, and air thins out, and produces negative pressure.Therefore, establish air inlet at the zone of positive pressure of factory building, negative pressuren zone is established exhaust outlet, and just in the air inlet inlet chamber, indoor gas drains into outdoor air from exhaust outlet, reaches the purpose of ventilation.
But in the lower area of temperature such as northwest and northeast, weather is very cold during winter, especially need close ventilating opening when checking factory building, increase heat insulation effect, so the insulation problem of ventilator is particularly important, has been subjected at present widely and has paid close attention to.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of high insulating effect, easy-to-install thermal-insulating type arcuate ventilator for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of thermal-insulating type arcuate ventilator, it is characterized in that, this ventilator comprises skeleton structure, weather shield, pulley, steel wire rope, valve plate and flashing plate, described skeleton structure is inverted isosceles-trapezium-shaped, and the chamfering on last base is curved, and described weather shield is located at the centre of skeleton structure, described pulley is located at the bottom of weather shield, described steel wire rope is connected on the pulley, and described valve plate is connected an end of steel wire rope, and described flashing plate is located at the bottom of skeleton structure.
Described weather shield has two, is the setting of " people " font.
Described valve plate is made of heat-preservation cotton and color steel, and described heat-preservation cotton is located at the top of color steel.
Described heat-preservation cotton thickness is 50mm.
Described valve plate is folding up and down under the effect of pulley and steel wire rope.
Described flashing plate is made of heat-preservation cotton and color steel.
Compared with prior art, reasonable structural arrangement of the present invention, it is little to conduct oneself with dignity, and anti-seismic performance is good, antiseptic property is good, and water resistance is good, long service life, and easy for installation, can play very big effect to the insulation of factory building, the insulation problem when having solved cold weather district work such as northern grade and having checked factory building.
Description of drawings
Fig. 1 is a structural representation of the present invention.
1 is that skeleton structure, 2 is that weather shield, 3 is that pulley, 4 is that steel wire, 5 is that valve plate, 6 is that flashing plate, 7 is that heat-preservation cotton, 8 is a color steel among the figure.
The specific embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment
A kind of thermal-insulating type arcuate ventilator, its structure as shown in Figure 1, this ventilator comprises skeleton structure 1, weather shield 2, pulley 3, steel wire rope 4, valve plate 5 and flashing plate 6, skeleton structure 1 is inverted isosceles-trapezium-shaped, the chamfering on last base is curved, weather shield 2 has two, be located at the centre of skeleton structure 1, be the setting of " people " font, pulley 3 is located at the bottom of weather shield 2, and steel wire rope 4 is connected on the pulley, and valve plate 5 is connected an end of steel wire rope 4, valve plate 5 is folding up and down under the effect of pulley 3 and steel wire rope 4, realize opening and closing, valve plate 5 is made of heat-preservation cotton 7 and color steel 8, and heat-preservation cotton 7 is located at the top of color steel 8, thereby can play good heat insulation effect, the thickness of heat-preservation cotton 7 is 50mm, and flashing plate 6 is located at the both sides of skeleton structure 1 bottom, is symmetrical distribution, this flashing plate 6 also is made of heat-preservation cotton 7 and color steel 8, can play certain insulation effect.
