Abstract
The utility model discloses a kind of all-welded ball valve, including valve body, lower valve rod and spheroid, lower valve rod is connected through valve body with spheroid, it is characterised in that：The valve stem sleeve being arranged on valve body is socketed with outside the lower valve rod, the lower valve rod bottom is provided with the plug screw that lower valve rod offsets, it is socketed in the plug screw in valve stem sleeve and is threadedly coupled with valve stem sleeve, by plug screw on valve stem sleeve up and down threads turn, to adjust height of the spheroid in valve, so that valve seat axis overlaps with ball centre line, solve installation or using when spheroid skew situation about being conveniently adjusted, and plug screw is welded on valve stem sleeve, so as to fix the position of lower valve rod；In addition, by way of welding, bottom is installed, sets the first sealing ring, to carrying out effective with multiple sealing at lower valve rod, to prevent from revealing at lower valve rod, sealing is relatively reliable to modes such as the 3rd sealing rings.
Description
Technical field
Valve field is the utility model is related to, specifically a kind of all-welded ball valve.
Background technology
All-welded ball valve is because valve seat is made up of carbonization teflon seal ring and disk spring, so to pressure and temperature
The change of degree is adaptable, mark pressure and temperature in the range of will not produce it is any let out cunning, have compact-sized, assembling side
Just the advantages that, it has been widely used in various fluid lines, waste gas is selected and puts pipeline, coal gas and heating power supply line, but full weldering
Access valve still has many weak points.The spheroid of all-welded ball valve when mounted, it is necessary to adjust height of the spheroid in valve body,
Overlap the axis of ball centre line and valve seat, but existing sphere installation is non-adjustable or adjustment is difficult, have impact on valve entirety
Use.
The content of the invention
The purpose of this utility model：The defects of in order to overcome prior art, the utility model provide a kind of adjustable sphere
The all-welded ball valve of height.
The technical solution of the utility model：Including valve body, valve seat, lower valve rod and spheroid, lower valve rod through valve body with
Spheroid is connected, and the valve stem sleeve being arranged on valve body is socketed with outside lower valve rod, and lower valve rod bottom is provided with the plug screw that lower valve rod offsets,
It is socketed in plug screw in valve stem sleeve and is threadedly coupled with valve stem sleeve.
Further, by being welded and fixed between plug screw and valve stem sleeve.
Further, the bottom of valve stem sleeve is additionally provided with bottom, and bottom is secured by bolts on valve stem sleeve.
Further, lower valve rod periphery be provided with valve stem sleeve sealing coordinate the first sealing ring, valve stem sleeve with
The second sealing ring is provided between plug screw, the 3rd sealing ring is provided between bottom and valve stem sleeve.
The beneficial effects of the utility model are：By plug screw on valve stem sleeve up and down threads turn, exist to adjust spheroid
Height in valve so that valve seat axis overlaps with ball centre line, solve installation or using when spheroid skew be conveniently adjusted
Situation, and plug screw is welded on valve stem sleeve, so as to fix the position of lower valve rod；In addition, by way of welding,
Bottom is installed, sets the first sealing ring, to carrying out effective with multiple sealing at lower valve rod, to be prevented down to modes such as the 3rd sealing rings
Revealed at valve rod, sealing is relatively reliable.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model specific embodiment；
Fig. 2 is the enlarged drawing at A in Fig. 1；
Wherein, valve body 1, valve seat 2, lower valve rod 3, spheroid 4, valve stem sleeve 5, plug screw 6, bottom 7, bolt 71, the first sealing
Circle 81, the second sealing ring 82, the 3rd sealing ring 83.
Embodiment
All-welded ball valve as shown in Figure 1 and Figure 2, including valve body 1, valve seat 2, lower valve rod 3 and spheroid 4, lower valve rod 3
It is connected through valve body 1 with spheroid 4, is socketed with the valve stem sleeve 5 being arranged on valve body 1 outside lower valve rod 3, the bottom of lower valve rod 3 is provided with
The plug screw 6 that lower valve rod 3 offsets, it is socketed in plug screw 6 in valve stem sleeve 5 and is threadedly coupled with valve stem sleeve 5, in installation spheroid 3
When there is axis runout with valve seat 2, plug screw is rotated using instrument, plug screw 6 moves up and down in valve stem sleeve 5, then lower valve rod 3
Slide, slowly move it toward required direction so as to prop up spheroid 4, the axis of last spheroid 4 and valve seat 2 overlaps therewith.
Plug screw 6 is fixed between plug screw 6 and valve stem sleeve 5 by way of welding, will not be easily so as to the position of lower valve rod 3
Change.
The bottom of valve stem sleeve 5 is additionally provided with bottom 7, and bottom 7 is fixed on valve stem sleeve 5 by bolt 71, lower valve rod 3
Periphery is provided with the first sealing ring 81 coordinated with the sealing of valve stem sleeve 5, and it is close to be provided with second between valve stem sleeve 5 and plug screw 6
Seal 82, is provided with the 3rd sealing ring 83 between bottom 7 and valve stem sleeve 5, bottom 7 is effectively protected to the inside of valve stem sleeve 5
Shield, the first sealing ring 81, the second sealing ring 82 and the 3rd sealing ring 83 are to carrying out effective with multiple sealing at lower valve rod 3.
