Abstract
Provided is an axial-flow fan for roof. A square check-valve is horizontally arranged below the air inlet panel of the roof axial-flow fan, the square check-valve is fixedly connected to the air inlet of the fan and is in a combined structure of movable louvre blades, the square check-valve consists of a valve and a plurality of movable louvre blades which are uniformly distributed and are in a upward overturn movable structure. By adopting the roof axial-flow fan equipped with the square check-valve, the air outdoor is isolated from the air indoor while the fan is shutdown ensuring the indoor temperature. The axial-flow fan for roof in the utility model has the characteristics of simple structure, convenient manufacture and installation, low cost and good application effect.
Description
Technical field
The utility model relates to a kind of roof axial-flow blower, belongs to the industrial fan product technical field.
Background technique
A large amount of at present at the RF-AXA of industrial use type roof axial-flow blower, its structure is: axial-flow blower adds the roof flashing cover structure, blower fan is installed on the top, house with plumbness, the roof flashing cover is positioned at the top of axial-flow blower, the roof axial-flow blower of this structure, can realize normal house ventilation operation, and when rainy, can stop entering of rainwater, but when blower fan is stopped using, the house is by the passage and extraneous the communicating of blower fan, like this when running into strong wind weather, the wind of outside can enter into the house by blower fan, in summer or winter, cold air in the house or heat also can be lost to the outside because of the circulation of air, bring influence to daily life simultaneously.
Summary of the invention
The utility model provides a kind of a kind of roof axial-flow blower of novelty, adopts safety check enclosed construction technology, to realize the purpose of roof with axial-flow blower isolated outside and indoor air ventilation when shutting down.
The technical solution adopted in the utility model is:
A kind of roof axial-flow blower is provided with below the intake grill panel of described roof axial-flow blower a square safety check is installed, the installation that is the level of state of square safety check, and the intake grill of square safety check and blower fan is connected and fixed.
Square safety check is an active type louvre blade fabricated structure, is made of valve body and some active type louvre blades, and the active type louvre blade is evenly distributed, and the active type louvre blade is the bascule that upwards overturns.
The utility model beneficial effect is:
Owing to adopted a kind of roof of the present utility model axial-flow blower; the square safety check of roof axial-flow blower band; isolated outside and indoor air ventilation when blower fan is shut down; guarantee room temperature; a kind of roof of the present utility model has with axial-flow blower: simple in structure; make easy for installationly, cost is low, the characteristics that using effect is good.
Description of drawings
Fig. 1: be the plan view of a kind of roof of the utility model with axial-flow blower;
Fig. 2: the A that is Fig. 1 is to view.
Among Fig. 1,2: square safety check 1.
Embodiment
As shown in Figure 1 and Figure 2.
A kind of roof axial-flow blower is provided with below the intake grill panel of described roof axial-flow blower a square safety check 1 is installed, installations that be the level of state of square safety check 1, and the intake grill of square safety check 1 and blower fan is connected and fixed.
Square safety check 1 is an active type louvre blade fabricated structure, is made of valve body and some active type louvre blades, and the active type louvre blade is evenly distributed, and the active type louvre blade is the bascule that upwards overturns.
Basic functional principle: when blower fan starts the outside exhaust ventilation of use, because the effect of wind-force, the active type louvre blade in the square safety check 1 upwards rises, and air discharges by square safety check 1 and blower fan, after blower fan quits work, the active type louvre blade is because the effect of self gravitation, return downwards, and the edge is folded mutually mutually, complete closed is lived the intake grill of blower fan, so just can realize the isolated of indoor and outside, stop air to circulate mutually, thereby guarantee room temperature.
Claims (2)
