Abstract
The utility model belongs to a ventilator, which is suitable for heat radiation and ventilation of hot shops of industrial enterprises. One cylinder body is connected with a throat opening which is supported on a preformed hole of a room; the throat opening is provided with a fan; a hollow cavity on the upper part of the cylinder body is fixed with a 'Y'-shaped waterproof board; the external side of the cylinder body is fixed with flow guiding boards which incline towards the same direction; the lower ends of the waterproof board and the flow guiding boards are respectively connected with a draining slot; hot air can upwards exhaust through gaps of the throat opening, an air valve, an internal cavity of the cylinder body, the waterproof board, and the flow guiding boards, and the purpose of natural ventilation can be realized. The ventilator has advantages of simple structure, no noise, long service life, once installation, and long-term benefit.
Description
The utility model belongs to a kind of ventilation equipment, and a kind of natural ventilation equipment that specifically is applied to the outside air draft of industrial enterprise's hot shop is a roof ventilator.
Existing industrial enterprise hot shop ventilates and generally adopts exhaust fan or roof ventilator etc. to realize forced ventilating by Electric Traction fan or blower fan.The deficiency that exists is to consume electric power, and noise is big, and the parts abrasion that runs up is big, maintenance and operating cost height.
The purpose of this utility model provides a kind of novel roof venting, makes its not electricity consumption, noiseless, reduction operation and maintenance cost.
The purpose of this utility model is achieved in that roof ventilator is connected with aditus laryngis by cylindrical shell, aditus laryngis is bearing on the roof preformed hole, the air-valve plate is housed on the aditus laryngis, cylinder lumen top is fixed with " people " font splash guard, is fixed with deflector with the equidirectional inclination of splash guard at its outside one determining deviation.Aditus laryngis and cylindrical shell shape of cross section are all garden shape or rectangle.The air-valve plate is connected with horizontal axis, can be around horizontal rotational shaft, the anglec of rotation be 0-90 ° adjustable, the air-valve plate is plate shaped or streamlined, is good with streamlined.Cylindrical shell is straight tubular or streamlined, is good with streamlined.Splash guard, deflector lower end are connected with rhone respectively.Aditus laryngis, cylindrical shell, splash guard, deflector are by frame fixation.
The utility model since critical pieces such as aditus laryngis, cylindrical shell, splash guard, deflector all by frame fixation, without Electric Traction, parts do not run up, so its conspicuous advantage is, as long as select suitable throat area and cylindrical shell height, the atmospheric pressure that the air bulk density difference that utilizes indoor/outdoor temperature-difference to cause produces is poor, can reach enough ventilation purposes equally.This device is natural ventilation, the power consumption, noise and the abrasion that do not exist the Electric Traction forced ventilation to cause, and long service life once drops into, long-term being benefited.
Be that embodiment is described further roof ventilator below with the accompanying drawing.
Fig. 1 is the roof ventilator front view.
Fig. 2 is the roof ventilator lateral view.
Fig. 3 is the rhone front view that splash guard and lower end thereof connect, and the deflector shape is similar with it.
Fig. 4 is the A-A sectional view among Fig. 3.
In Fig. 1 and Fig. 2; 1 is aditus laryngis, 2 air-valve axles for the level installation, dotted line shown in 3 is in the position that level is closed for the air-valve plate, and 4 is the air-valve plate, and 11 4 faces of biside plate 5 and wallboard fence up and constitute the roof ventilator cylindrical shell, 6 is the splash guard rhone, 7 is splash guard, and 8 is the deflector rhone, and 9 is deflector, the rainy day rainwater drops on splash guard and the deflector hydrophobic through rhone downwards, and 10 is end plate.Aditus laryngis, cylindrical shell, splash guard, deflector are fixed by frame supported, omit among the figure.Indoor hot air is upwards upwards discharged in the space between air-valve, cylinder lumen and splash guard, deflector from aditus laryngis.
