Description
Technical Field
The utility model relates to a fan technical field, in particular to novel high-efficient butterfly damper of self-closing formula.
Background
The fan is a machine which can increase the gas pressure and discharge the gas by means of the input mechanical energy, and is widely used for ventilation, dust exhaust and temperature reduction of breeding houses, factories, mines, tunnels and buildings; because livestock, personnel, equipment are more in animal and poultry house, factory building or the large-scale building, the outer wall need be adorned a plurality of fans and be used for indoor taking a breath, and the air intake of fan generally is equipped with the blast gate, and the blast gate of prior art is mostly the shutter, and the shutter is closed automatically after closing the fan, prevents that sleet from entering into indoorly.
However, the shutter type air valve has the following disadvantages: firstly, the louver is arranged at the position of the air inlet, and a plurality of supporting frames interfere the air flow to form wind resistance; secondly, the number of shutter components is large, the number of fit clearance gaps is large, and the heat preservation effect is poor; and the friction between the shutter assembly and air is large, so that noise pollution is caused.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model discloses a realize through following technical scheme:
the utility model provides a novel high-efficient butterfly-shaped air valve of self-closing formula, includes the shell, the shell is the ring form, the shell is equipped with bottom surface, top surface, the top surface slope sets up, a butterfly door is connected to the top surface, butterfly door and the laminating of shell top surface, the butterfly door includes the pivot, the top and the bottom at the shell top surface are fixed respectively at the both ends of pivot, articulated a plurality of hinges in the pivot, door plant one is connected to the left part blade of hinge, door plant two is connected to the right part blade of hinge, door plant one, door plant two surfaces are equipped with a plurality of waist shape tongue.
As a preferred scheme, the included angle between the top surface and the bottom surface of the shell is 7-10 degrees.
Preferably, the first door panel and the second door panel are both semicircular.
Preferably, the shell and the butterfly door are made of glass fiber reinforced plastics.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a butterfly door adopts the tilting design, does not rely on drive arrangement, relies on self gravity to close, and tilting butterfly door design, the windage is little, and sealing performance is good, and the butterfly door is closed the back and is minimum to the area that shelters from of shell top surface, can realize furthest's ventilation.

Detailed Description
The invention will be described in further detail with reference to the following detailed description and accompanying drawings:
the utility model provides a novel high-efficient butterfly-shaped air valve of formula of closing certainly, includes shell 1, shell 1 is the ring form, shell 1 is equipped with bottom surface 101, top surface 102 slope sets up, a butterfly door 2 is connected to top surface 102, butterfly door 2 and the laminating of 1 top surface 102 of shell, butterfly door 2 includes pivot 201, the top and the bottom at 1 top surface 102 of shell are fixed respectively at the both ends of pivot 201, articulated a plurality of hinges 3 in the pivot 201, door plant one 202 is connected to hinge 3's left part blade 301, door plant two 203 is connected to hinge 3's right part blade 302, door plant one 202, door plant two 203 surface are equipped with a plurality of waist shape tongue 204, and the setting up of tongue can cushion axial fan and open the impact of wind to door plant one 202, door plant two 203 in the twinkling of an eye, avoids the deformation of door plant one 202, door plant two 203.
Further, the included angle between the top surface 102 and the bottom surface 101 of the housing 1 is 7-10 °.
Further, the first door panel 202 and the second door panel 203 are both semicircular.
Furthermore, the shell 1 and the butterfly door 2 are made of glass fiber reinforced plastics.
The butterfly air valve is matched with an axial flow fan for use, when the axial flow fan is opened, airflow drives the inclined butterfly door 2 to be opened, the first door plate 202 and the second door plate 203 rotate towards the middle around the rotating shaft 201, at the moment, the top surface 102 of the shell 1 is in an open state, the purpose of ventilation flowing is achieved, after the axial flow fan is closed, the inclined butterfly door 2 is driven by the gravity of the inclined butterfly door 2 to be closed, and the first door plate 202 and the second door plate 203 rotate around the rotating shaft 201 to be attached to the top surface 102 of the shell 1 under the action of no external force due to the gravity, so that the sealing.
The above detailed description of the embodiments of the present invention is only used as an example, and the present invention is not limited to the above described embodiments, and the modifications of the present invention are also within the scope of the present invention.
