Abstract
A one-way ventilating inversion-preventing automatic window is composed of laneway edges (4). The utility model is characterized in that one side of laneway edge (4) is movably connected with a hinge (1). The other side is fixedly connected with a sealing wall (2). A main fan (3) is fixedly connected with the laneway edge (4) through a sealing wall (2). Therefore the one-way ventilating inversion-preventing automatic window has the advantages of simple structure, time saving, forcing saving and easy operation. The one-way ventilating inversion-preventing automatic window according to the utility model is especially suitable for mining.
Description
Technical field:
The utility model relates to a kind of automatic air regulator, and converse automatic air regulator is prevented in particularly a kind of unidirectional ventilation.
Background technology:
At present, the effect of the restricted air quantity of ventilation equipment such as the air door air regulator that adopts in the underground mine ventilation system, formation pressure reduction, wherein, air door plays and prevents to leak out and guarantee to prevent when negative pressure forms that distinguished and admirable converse effect, air regulator from playing the effect that allows wind circulation to cross and limit the size of air quantity.But in the application of underground tunneling roadway, because the space, down-hole is limited, can not construction possess simultaneously under the negative pressure condition that unidirectional active wind circulation is crossed and mechanical ventilation is caused when air-conditioning requirement limits if having time and prevent distinguished and admirable converse engineering services, and conversion in both cases needs Artificial Control, wastes time and energy, inconvenient operation.
Summary of the invention:
The purpose of this utility model is exactly to provide a kind of unidirectional ventilation simple in structure, time saving and energy saving, simple to operate to prevent converse automatic air regulator.
The purpose of this utility model is achieved in that a kind of unidirectional ventilation prevents converse automatic air regulator, form by limit, tunnel group (4), a side that it is characterized in that limit, described tunnel group (4) flexibly connects loose-leaf (1), the fixedly connected fire dam of opposite side (2), main fan (3) is fixedlyed connected with limit, tunnel group (4) by fire dam (2).
The utility model compared with prior art has the following advantages:
Owing to adopt a side of limit, tunnel group (4) to flexibly connect loose-leaf (1), the fixedly connected fire dam of opposite side (2), the form of structure that main fan (3) is fixedlyed connected with limit, tunnel group (4) by fire dam (2), thus simple in structure, time saving and energy saving, simple to operate.
Description of drawings:
Fig. 1: be the utility model concrete structure schematic diagram
Fig. 2: be the utility model A-A sectional drawing
1, connects loose-leaf 2, fire dam 3, main fan 4, limit, tunnel group
The specific embodiment:
One side of limit, tunnel group (4) flexibly connects loose-leaf (1), the fixedly connected fire dam of opposite side (2), and main fan (3) is fixedlyed connected with limit, tunnel group (4) by fire dam (2).
During use, when main fan did not turn round, loose-leaf was a normally open, distinguished and admirable can normally passing through, when main fan turned round, the loose-leaf opening direction formed negative pressure, and the pressure of generation is closed loose-leaf, thereby can prevent distinguished and admirable converse, guaranteed the uniformity of wind direction under different situations, out-of-date when the needs wind circulation, air regulator is opened automatically, air regulator is closed automatically when needing blocking-up distinguished and admirable, can use.
Claims (1)
1, the anti-converse automatic air regulator of a kind of unidirectional ventilation, form by limit, tunnel group (4), a side that it is characterized in that limit, described tunnel group (4) flexibly connects loose-leaf (1), the fixedly connected fire dam of opposite side (2), and main fan (3) is fixedlyed connected with limit, tunnel group (4) by fire dam (2).
