Described thin slice comprises two limits being parallel to each other, and the one end on two limits is connected by a junction, forms a seam between two limits
Gap, described gap forms a circular hole in the one end near connecting portion, and the thickness of described thin slice is 0.1-0.14mm, described limit and seam
The width ratio of gap is 5:2, and the diameter of described circular hole and the width ratio in gap are 2:1, and the surfaces externally and internally of valve stem sleeve is frosting, thin
Sheet copper strontium nickel alloy is made, and wherein the weight part ratio of copper strontium nickel is 120:13:5.
As preferred embodiment of the present invention, described closing cover and flange are one-body molded, and closing cover and flange are by polychlorostyrene
Ethylene transparent plastic is made.
As preferred embodiment of the present invention, the alloy surface of described valve stem sleeve is coated with layer oxide film.
The flange hard seal butterfly valve valve rod fastening assembly of the present invention is installed between valve rod and baffle plate, and this fastening assembly is at valve
Under the effect of bar rotation torsion, thin slice self can deform upon, and valve stem sleeve can be closely attached to valve rod table by this deformation
Face, torsion is the biggest to be attached the tightest, thus substantially increases the steadiness between valve rod and catch, extends flange and firmly seal
The service life of butterfly valve.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
In having technology to describe, the required accompanying drawing used is briefly described, it should be apparent that, the accompanying drawing in describing below is only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to
Other accompanying drawing is obtained according to these accompanying drawings.
Fig. 1 is the perspective exploded view of flange hard seal butterfly valve valve rod fastening assembly of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings the preferred embodiments of the present invention are described in detail, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
As it is shown in figure 1, a kind of flange hard seal butterfly valve valve rod fastening assembly 1, comprise a valve stem sleeve 20, the one of valve stem sleeve 20
End is provided with a closing cover 10, and closing cover 10 is provided with a flange 11, described flange 11 and valve stem sleeve 20 phase clamping, described valve stem sleeve
20 are formed by the interconnection of multiple " u "-shaped thin slice 30, and described thin slice 30 comprises two limits being parallel to each other 31, the one of two limits 31
End is connected by a junction 32, forms a gap 33 between two limits 31, and described gap 33 is in the one end near connecting portion 32
Forming a circular hole 34, the thickness of described thin slice 30 is 0.1-0.14mm, and the width ratio in described limit 31 and gap 33 is 5:2, described
The diameter of circular hole 34 is 2:1 with the width ratio in gap 33, and the surfaces externally and internally of valve stem sleeve 20 is frosting, and thin slice 30 copper strontium nickel closes
