Technical field
The utility model relates to butterfly valve technical field more particularly to a kind of valve axis adjustment devices of vertical butterfly valve.
Background technique
Butterfly valve is called flap valve, is a kind of simple regulating valve of structure, can be used for the switch control of low pressure pipeline medium
Butterfly valve refers to that closure member (flap or butterfly plate) is disk, a kind of valve of open and close is reached around valve shaft rotation, valve can
For controlling the various types such as empty gas and water, steam, various corrosive medias, mud, oil product, liquid metal and radiating medium
The flowing of fluid.Cutting and throttling action are mainly played on pipeline.Butterfly valve opening and closing element is a discoidal butterfly plate, in valve body
Axis around its own rotates, to achieve the purpose that opening and closing or adjusting.
However when the vertical installation of existing butterfly valve, the weight of valve shaft and butterfly plate directly acts on hubcap by the bottom end of valve shaft
Plane on, and after long-term use, valve shaft end and hubcap constantly rotate generation friction mill due to valve frequently opens and closes
Under the condition of self-weight, butterfly plate and valve shaft can generate stress deformation for damage, the in addition vertical installation of butterfly valve, valve shaft and butterfly plate.Both the above
Factor causes valve shaft and butterfly plate to sink, and causes butterfly plate sealing ring and valve seals to misplace, sealing pair cannot the complete contract heart
It coincide, the problem of sealing by-produced leakage, butterfly plate is caused to be not closed completely.
Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and a kind of vertical butterfly valve proposed
Valve axis adjustment device.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of valve axis adjustment device of vertical butterfly valve, including valve body, the inner wall of valve body are rotatably connected to valve shaft, cover on valve shaft
It is connected to butterfly plate, the lower end of the valve shaft, which contradicts, cylindricality jacking block, valve pocket is socketed on cylindricality jacking block, the upper end of valve pocket and valve body can
Dismantling connection, the lower end of valve pocket are removably connected with end cap, and indicator, the cylindricality jacking block are equipped between end cap and cylindricality jacking block
Sidewall thread be connected with fixed link, and the side wall of valve pocket is equipped with sliding mouth corresponding with fixed link, and screw thread connects on the valve pocket
It is connected to screwed ring, and the inner ring of screwed ring is equipped with annular groove corresponding with fixed link.
Preferably, the indicator includes the plectane for being against cylindricality jacking block bottom, and the bottom of plectane is connected separately with spring
One end and scale one end, the other end of spring connect with end cap, and the other end of scale runs through end cap.
Preferably, the screwed ring includes two annulus, and two annulus are connected by stay bolt, and the annular groove opens up
In the junction of two annulus.
Preferably, the valve pocket is connected by screw to valve body, end cap and valve pocket.
Preferably, it is socketed with upper seal on the valve shaft, is socketed with lower seal on the cylindricality jacking block.
Compared with prior art, the utility model has the beneficial effects that the utility model structure is simple, when valve shaft and butterfly plate
When sinking, valve shaft can press scale by cylindricality jacking block, according to the variation of scale numerical value corresponding with end cap bottom, rotate spiral shell
Line ring drives cylindricality jacking block to rise by fixed link, by valve shaft top Hui Yuanwei, guarantees that butterfly plate sealing ring and valve seals will not
Dislocation, sealing pair is overlapped with one heart, avoids leakage problem, solve the problems, such as that butterfly plate is not closed completely, and scale there are observables
Sealing pair degrees of offset judges whether to adjust.
Detailed description of the invention
Fig. 1 be the utility model proposes structural schematic diagram；
Fig. 2 is part A structural schematic diagram in Fig. 1.
In figure: valve body 1, cylindricality jacking block 2, screwed ring 3, annulus 301, stay bolt 302, end cap 4, upper seal 5, valve shaft 6,
Lower seal 7, fixed link 8, indicator 9, plectane 901, spring 902, scale 903, valve pocket 10.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-2, a kind of valve axis adjustment device of vertical butterfly valve, including valve body 1, the inner wall of valve body 1 are rotatably connected to
Valve shaft 6 is socketed with butterfly plate on valve shaft 6, and the lower end of valve shaft 6, which contradicts, cylindricality jacking block 2, and valve pocket 10, valve are socketed on cylindricality jacking block 2
The upper end of set 10 is detachably connected with valve body 1, and the lower end of valve pocket 10 is removably connected with end cap 4, end cap 4 and cylindricality jacking block 2 it
Between be equipped with indicator 9, the sidewall thread of cylindricality jacking block 2 is connected with fixed link 8, and the side wall of valve pocket 10 is equipped with and 8 phase of fixed link
Corresponding cunning mouth, screwed ring 3 is threaded on valve pocket 10, and the inner ring of screwed ring 3 is equipped with ring corresponding with fixed link 8
Shape slot, valve pocket 10 are connected by screw to valve body 1, end cap 4 and valve pocket 10, easy access, are socketed with upper seal on valve shaft 6
5, lower seal 7 is socketed on cylindricality jacking block 2, prevents from falling into dust.
Indicator 9 includes the plectane 901 for being against 2 bottom of cylindricality jacking block, and the bottom of plectane 901 is connected separately with spring 902
One end and scale 903 one end, the other end of spring 902 connect with end cap 4, and the other end of scale 903 runs through end cap 4, leads to
