Description
Technical field
It the utility model is related to valve mechanism, the valve plate of more particularly to a kind of eccentric rotary and the air door using the valve plate
Valve.
Background technology
Eccentric valve is the conventional valve in pipe-line system, mainly inclined including single eccentric valve, double eccentric valves, three eccentricity valve, change
Heart valve, bias therein are primarily referred to as：The skew that shaft centerline is formed with sealing surface of valve plate, shaft centerline and valve body
The skew that center line is formed, the skew that valve body sealing surface center line is formed with valve body center line, i.e. normal conditions
Under, rotating shaft extends radially through valve plate vertical centerline, and shaft axis overlap with valve plate vertical centerline, by changing rotating shaft
Position in valve body, each eccentric structure is realized, meanwhile, the shape and structure of valve body sealing surface is adjusted, drives the rotation of rotating shaft
Valve plate rotates, and then realizes the sealing of valve body internal channel.
But valve plate is still in rotation process and rotated around the axis, it is from valve plate center to valve plate side that it, which rotates the arm of force,
The distance of edge, when the flow media in valve body promotes valve plate to rotate, because it rotates the arm of force from valve plate center to valve plate edge
All same, when making to be turned on and off valve, valve plate initial rotation speed is slower, causes the time lengthening for being turned on and off valve,
Be unfavorable for commonly using air door valve in the quick acting of valve, particularly pipeline, it is wind-force to open medium due to it, the rotation of valve plate compared with
Easily influenceed by wind-force is continually changing, cause to be turned on and off slower.
In summary, need badly at present and want a kind of technical scheme, solve existing shaft axis and overlapped with valve plate vertical centerline,
When causing to be turned on and off valve, valve plate initial rotation speed is slower, is turned on and off the time lengthening of valve, is unfavorable for valve
Quick acting technical problem.
Utility model content
The purpose of this utility model is：Overlapped for existing shaft axis with valve plate vertical centerline, cause open or
When closing valve, valve plate initial rotation speed is slower, causes the time lengthening for being turned on and off valve, is unfavorable for the quick of valve
The technical problem of action, there is provided a kind of valve plate of eccentric rotary and the air door valve using the valve plate.

Valve plate heavier mass, it is easier to the valve plate towards relative thin side in closing process and rotates, further facilitate the rotation of valve plate,
Accelerate the closing of valve plate, reduce the shut-in time for the valve that the valve plate is set.
Air door valve, including valve body, at least one valve plate as described above is provided with valve body.
The air door valve of the present embodiment, because pumped (conveying) medium is wind, in closing process, wind-force is unstable to the thrust of valve plate
Fixed, closing velocity is slower, still, due to there is provided the valve plate of above-mentioned eccentric rotary, making valve plate in closing process, not only by
The impetus of wind-force, also by itself is due to double eccentric structures and caused both sides weight is uneven, the unbalanced situation of the arm of force
Influence, rotate valve plate quick, closing is rapider, is particularly conducive to the closing of air door valve.
Preferably, the central axis of the axis hole and the center axis deviation of valve body.By the central axis and valve of axis hole
The central axis of body is arranged to deviate, and realizes the air door valve of three eccentricity structure, further increases eccentric quantity, makes opening for air door valve
Open or close all smoothly.
Preferably, the central axis of the valve body and the center line of valve body sealing surface deviate.By the central axis of valve body
Deviate with the center line of valve body sealing surface, realize the air door valve of four eccentric structures, further increase eccentric quantity, close valve plate
Contacted well between sealing surface during state, sealing effectiveness is preferable.
Preferably, angle M, 0 ° of ＜ M≤15 ° are provided between the section of the valve plate and the valve body.Valve plate is inclined
Tiltedly it is arranged in valve body, valve plate is there is the trend of a rotation in original state, when valve plate is by medium promotion or artificial
When controlling valve plate rotation, rotate and be more convenient, further facilitate being turned on and off for air door valve.
In summary, by adopting the above-described technical solution, the beneficial effect of the valve plate of eccentric rotary of the present utility model
It is：
By the way that valve shaft to be covered to the central axis of upper shaft hole and the center axis deviation of valve plate axle sleeve, valve plate is set to turn around the shaft
When dynamic, the arm of force of the valve plate of rotating shaft both sides differs, and the valve plate of long arm of force side easier can be realized by medium thrust and turns
It is dynamic, and then realize and the quick of valve is turned on and off, facilitate the rotation of valve plate, the valve opening of the setting valve plate is relatively held
Easily；
The beneficial effect of air door valve of the present utility model is：
Due to there is provided the valve plate of above-mentioned eccentric rotary, making valve plate in closing process, not only being made by the promotion of wind-force
With, also by itself due to double eccentric structures and caused both sides weight is uneven, the unbalanced situation of the arm of force is influenceed, turn valve plate
Dynamic quick, closing is rapider, is particularly conducive to the closing of air door valve.
