Abstract
The invention discloses a kind of butterfly valve adjusting means, comprising a bonnet, a valve rod is rotationally provided with the opening of bonnet, a sealing shroud is provided between bonnet and valve rod, the top of sealing shroud is provided with an adjustment flange, the bottom surface for adjusting flange is interior thick outer thin inclined-plane, adjustment flange is provided with two screws, fixed with bonnet by one first screw rod and one second screw rod respectively, first screw rod and the second screw rod are symmetrical centered on valve rod, one first raised and one second projection is provided with opening in bonnet upper surface, described first is raised symmetrical centered on valve rod with the second projection.The lower inclined plane and projection contacts of flange when butterfly valve adjusting means of the invention is used, elastic by adjusting screw rod can make flange overall in raised top edge, and then band ovable valve stem integrally shifts, the axle center of valve rod so can be just controlled by the regulation of screw rod, can be rapidly adjusted when axle center offsets.
Description
Technical field
The present invention relates to butterfly valve manufacture field, more precisely, being a kind of butterfly valve adjusting means.
Background technology
Butterfly valve is a kind of regulating valve of simple structure, and the butterfly valve that can be used for the switch control of low pressure pipeline medium refers to close
Part（Flap or butterfly plate）Be disk, reach a kind of valve of open and close around valve shaft rotation, valve can be used to controlling air,
The flowing of all kinds fluids such as water, steam, various Korrosionsmediums, mud, oil product, liquid metal and radiating medium.
It is main on pipeline to play cut-out and throttling action.Butterfly valve opening and closing element is a discoidal butterfly plate, around the axle of its own in valve body
Line rotates, so as to reach the purpose for opening and closing or adjusting.The upper valve rod of butterfly valve is susceptible to partially with valve body in the presence of for a long time
The service life of butterfly valve is shortened in the heart, the sealing between influence valve rod and valve body.
The content of the invention
The present invention mainly solves the technical problem existing for prior art, so as to provide a kind of butterfly valve adjusting means.
Above-mentioned technical problem of the invention is mainly what is be addressed by following technical proposals：
A kind of butterfly valve adjusting means, comprising a bonnet, is rotationally provided with a valve rod in the opening of bonnet, set between bonnet and valve rod
The top for having a sealing shroud, sealing shroud is provided with an adjustment flange, and the bottom surface for adjusting flange is interior thick outer thin inclined-plane, adjusts flange
Be provided with two screws, fixed with bonnet by one first screw rod and one second screw rod respectively, the first screw rod and the second screw rod with
Centered on valve rod symmetrically, one first raised and one second projection, described first are provided with opening in bonnet upper surface
Raised and the second projection is symmetrical centered on valve rod.
Used as preferred embodiments of the present invention, described sealing shroud is integrally formed with adjustment flange.
Used as preferred embodiments of the present invention, described sealing shroud is made of stainless steel with adjustment flange.
The lower inclined plane and projection contacts of flange when butterfly valve adjusting means of the invention is used, elastic by adjusting screw rod can
So as to flange is overall integrally be shifted in raised top edge, and then band ovable valve stem, so can just be controlled by the regulation of screw rod
The axle center of valve rod processed, can rapidly be adjusted when axle center offsets.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
The accompanying drawing to be used needed for having technology description is briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is the structural representation of butterfly valve adjusting means of the invention.
Specific embodiment
The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
As shown in figure 1, a kind of butterfly valve adjusting means 1, comprising a bonnet 10, one is rotationally provided with the opening of bonnet 10
Valve rod 20, is provided with a sealing shroud 31 between bonnet and valve rod 20, the top of sealing shroud 31 is provided with an adjustment flange 32, adjusts flange 32
Bottom surface be interior thick outer thin inclined-plane, adjustment flange 32 is provided with two screws, respectively by one first screw rod 41 and one second
Screw rod 42 is fixed with bonnet 10, and the first screw rod 41 and the second screw rod 42 are symmetrical centered on valve rod 20, in the upper table of bonnet 10
Face is provided with one first raised 51 and one second projection 52 at opening, and the described first raised 51 and second projection 52 is with valve rod 20
Centered on symmetrically.
Used as to further improvement of the present invention, described sealing shroud 31 is integrally formed with adjustment flange 32.
Used as to further improvement of the present invention, described sealing shroud 31 is made of stainless steel with adjustment flange 32.
The lower inclined plane and projection contacts of flange when the butterfly valve adjusting means of the invention is used, elastic by adjusting screw rod can
So as to flange is overall integrally be shifted in raised top edge, and then band ovable valve stem, so can just be controlled by the regulation of screw rod
The axle center of valve rod processed, can rapidly be adjusted when axle center offsets.
Below mentality of designing of the invention is only illustrated in one embodiment, and in the case where system is allowed, the present invention can
To expand to external more functional modules simultaneously, so as to extend its function to greatest extent.
The above, specific embodiment only of the invention, but protection scope of the present invention is not limited thereto, and it is any
The change or replacement expected without creative work, should all be included within the scope of the present invention.Therefore, it is of the invention
Protection domain should be determined by the scope of protection defined in the claims.
