Abstract
The utility model discloses a kind of from opening and closing butterfly valve, it include tube body and butterfly plate, the inner wall of tube body is fixed with the fixing seat laterally to overhang, the butterfly plate and the projecting end of fixing seat are hinged, and articulated shaft deviates body central line certain distance, butterfly plate is divided into the small portion of smaller portions and the big portion of major part with hinge axes.Since the utility model is mounted with that the butterfly plate of butterfly valve is set as rotating with eccentric articulated shaft, and butterfly plate is divided into smaller part and larger portion by hinge axes from butterfly valve is opened and closed in cooling duct.When axial flow blower is opened, butterfly valve is automatically turned on by leeway using size two parts.When axial flow blower stops, the two-part weight difference of size can drive butterfly plate to be automatically closed, and the high-temperature hot-air in roller kilns or insulating box can be effectively prevent to flow backward evolution.
Description
Technical field
The utility model relates to butterfly valve technical field, in particular to can automatic open close butterfly valve.
Background technique
Mostly no design does not prevent hot wind from falling to the axial flow blower cooling duct of traditional architecture ceramic roller kiln or dry insulating box
Fill the butterfly valve of evolution.When in process of production, when closing axial flow blower because of process requirement, the height in roller kilns or insulating box is warmed
Wind can reversely be escaped by cooling duct, lead to the motor for burning out axial flow blower and electric wire, and the hot wind escaped also will affect
Air environment in workshop.
Utility model content
The technical problems to be solved in the utility model is to fall for the high-temperature hot-air in roller kilns or insulating box from cooling duct
Fill the butterfly valve of the automatic open close of evolution.
Used technical solution to solve above-mentioned technical problem: it is a kind of from opening and closing butterfly valve, it include tube body and butterfly plate,
It is characterized by: the inner wall of the tube body is fixed with the fixing seat laterally to overhang, the projecting end of the butterfly plate and fixing seat is hinged,
And articulated shaft deviates body central line certain distance, butterfly plate is divided into small portion and the major part of smaller portions with hinge axes
Big portion.
On the basis of the above, the counterweight for being reduced the weight difference in small portion and big portion is installed on the butterfly plate in medium and small portion.
On the basis of the above, the inner wall of the tube body is fixed with gear respectively at the small portion of butterfly plate and the closing direction side in big portion
Item.
Using brought by the utility model the utility model has the advantages that since the utility model is mounted with from opening and closing in cooling duct
Butterfly valve, the butterfly plate of butterfly valve are set as rotating with eccentric articulated shaft, and butterfly plate is divided into smaller part and larger portion by hinge axes.When axis stream
When blower is opened, butterfly valve is automatically turned on by leeway using size two parts.When axial flow blower stops, size is two-part
Weight difference can drive butterfly plate to be automatically closed, and the high-temperature hot-air in roller kilns or insulating box can be effectively prevent to flow backward evolution.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the utility model from opening and closing butterfly valve；
Fig. 2 is sectional view of the utility model from opening and closing butterfly valve.
Specific embodiment
As shown in Figs. 1-2, a kind of from opening and closing butterfly valve, it include tube body 1 and butterfly plate 2, the inner wall of the tube body 1 is fixed with
The fixing seat 3 laterally to overhang, the butterfly plate 2 and the projecting end of fixing seat 3 are hinged, and articulated shaft deviates one spacing of body central line
From butterfly plate 2 is divided into the small portion 21 of smaller portions and the big portion 22 of major part with hinge axes.In the present embodiment, butterfly plate 2 with
Fixing seat 3 is hinged using hinge 4.When work, axial flow blower is opened, due to the area portion too small greatly of 22 wind-engaging of big portion of butterfly plate 2
21, size two parts can generate leeway, and leeway can drive butterfly plate 2 to be turned into open state.When axial flow blower is shut down, greatly
Small two-part weight difference can drive the auto-reverse closing of butterfly plate 2, to effectively prevent the high warm in roller kilns or insulating box
Wind-fall fills evolution.
It, can be in installation counterweight 5 on the butterfly plate 2 in small portion 21 to reduce the small portion 21 of butterfly plate 2 and the weight difference in big portion 22.Size
The excessive weight difference of two parts can make the unlatching of butterfly plate 2 need biggish wind pressure, it is clear that this is undesirable problem.
For the sealing performance for reinforcing butterfly valve, the inner wall of the tube body 1 is respectively at the small portion 21 of butterfly plate 2 and the pass in big portion 22
It closes direction side and is fixed with blend stop 6.When butterfly valve is closed, the edge in the small portion 21 of butterfly plate 2 and big portion 22 respectively with respective blend stop 6
It is in close contact, forms curved seal structure, reduce hollow between butterfly plate 2 and tube body 1.
Claims (1)
1. it is a kind of from opening and closing butterfly valve, it include tube body and butterfly plate, it is characterised in that: the inner wall of the tube body is fixed with laterally outstanding
The projecting end of the fixing seat stretched, the butterfly plate and fixing seat is hinged, and articulated shaft deviate body central line certain distance, butterfly plate with
Hinge axes are divided into the small portion of smaller portions and the big portion of major part, on the butterfly plate in medium and small portion installation be reduced small portion and
The counterweight of the weight difference in big portion, the inner wall of the tube body are fixed with gear respectively at the small portion of butterfly plate and the closing direction side in big portion
Item, when butterfly valve is closed, the small portion of butterfly plate and the edge in big portion are in close contact with respective blend stop respectively, form curved seal structure,
Butterfly plate is hinged using hinge with fixing seat.
