Description

Middle control line Hand-operated butterfly valve
Technical field
The utility model is related to control line Hand-operated butterfly valve in one kind, and in particular to a kind of middle control line hand adjustment for being easy to safeguard Valve, belongs to valve technology field.
Background technology
Butterfly valve is called flap valve, is a kind of regulating valve of simple structure, can be used for the switch control of low pressure pipeline medium Butterfly valve refers to closure member(Flap or butterfly plate)It is disk, a kind of valve of open and close is reached around valve shaft rotation, valve can For controlling all kinds such as empty gas and water, steam, various Korrosionsmediums, mud, oil product, liquid metal and radiating medium The flowing of fluid.It is main on pipeline to play cut-out and throttling action.Butterfly valve opening and closing element is a discoidal butterfly plate, in valve body Rotated around the axis of its own, so as to reach the purpose for opening and closing or adjusting.
Butterfly valve can be divided into board-like biasing, vertical board-like, ramp type and lever by structure type.Can be soft close by seal form Two kinds of envelope type and hard closed type.Flexible sealing type is typically sealed using rubber ring, and hard closed type generally uses metal loop seals.By even Direct type formula can be divided into flange connection and wafer type connection;By the kind of drive can be divided into manually, gear drive, it is pneumatic, surge and electricity It is dynamic several.
Hand-operated butterfly valve is widely used, but due to usually carrying out soft seal to it using rubber ring inside butterfly valve, its pressure and Working range is smaller, and nonetheless, rubber ring is still easily damaged, once because being heated or corrode after rubber ring damages, it is logical Chang Huiyu valve seat adhesions, are extremely difficult to repair or change.
The content of the invention
The purpose of this utility model is to overcome above-mentioned weak point, there is provided a kind of device of uniform stirring glue.
According to the technical scheme that the utility model is provided, middle control line Hand-operated butterfly valve, including valve seat, valve plate, valve seat lining ring, valve Bar and handle;Valve seat lining ring is provided with the valve seat, valve plate is arranged in valve seat by valve seat lining ring;The valve plate connects with valve rod Connect, valve rod is connected with handle;Be additionally provided with dividing busing between the valve seat lining ring and valve seat, the dividing busing include axle sleeve and Extension;The extension radially extends with the center of circle of axle sleeve as the center of circle to axle sleeve, forms the circle with the center of circle of axle sleeve as the center of circle Ring.
The valve seat lining ring is identical with valve base inner wall material.Gap is formed between the valve seat lining ring and valve seat to coordinate.Institute The width for stating extension is more than valve seat wall thickness.
The beneficial effects of the utility model:The utility model simple structure, axle sleeve is installed additional come real by existing butterfly valve Now to the simple replacement of rubber ring lining ring, it is with low cost that it is transformed, and maintains easily, simple to operate, is suitable to large-scale application.

Specific embodiment
As Figure 1-3:Middle control line Hand-operated butterfly valve, including valve seat 1, valve plate 2, valve seat lining ring 3, valve rod 4 and handle 5;Institute State and be provided with valve seat lining ring 3 in valve seat 1, valve plate 2 is arranged in valve seat 1 by valve seat lining ring 3;The valve plate 2 is connected with valve rod 4, Valve rod 4 is connected with handle 5;Dividing busing 6 is additionally provided between the valve seat lining ring 3 and valve seat 1, the dividing busing 6 includes axle Set 6-1 and extension 6-2;The extension 6-2 with the center of circle of axle sleeve 6-1 as the center of circle, to axle sleeve 6-1 radially extend, formed with The center of circle of axle sleeve 6-1 is the annulus in the center of circle.
The valve seat lining ring 3 is identical with the inner-wall material of valve seat 1.Gap is formed between the valve seat lining ring 3 and valve seat 1 to match somebody with somebody Close.Wall thickness of the width of the extension 6-2 more than valve seat 1.
When the utility model is assembled, valve plate 2 is installed on the diametric(al) of pipeline, valve plate 2 revolves with handle 5 around axis Turn, the anglec of rotation is between 0-90 degree, when rotating to 90 degree, valve is full-gear.The utility model is served as a contrast in valve seat 1 and valve seat Install material and the identical dividing busing 6 of valve seat 1 between circle 3 additional, dividing busing 6 is provided with the annulus extension 6-2 of protrusion, every Gap is formed between bushing 6 and valve seat 1 to coordinate.
When valve seat lining ring 3 corrode or damage need change when, it is only necessary to the related valve seat lining ring 3 of dividing busing 6 is together taken Under, you can it is maintained or repairs.
Due to extension 6-2 width more than valve seat 1 wall thickness, the fluid passed through in valve will not rush in valve seat 1 with In gap between dividing busing 6, by the cooperation of dividing busing 6 and valve seat lining ring 3, preferably sealing still can be realized.
