Abstract
A kind of adjustable pre-tightening valve seat, including the valve seat in valve body, pass through packing seal between valve seat and valve body, filler is arranged in the packing cavity between valve seat and valve body by pushing block, spring and adjusting seat are axially set gradually between pushing block and valve body, adjusting seat is fixed by screw thread and valve body, and adjusting seat is axially movable the decrement of adjustment spring, and then adjusts the pretightning force between valve seat and spheroid.The beneficial effects of the utility model are：During assembling, adjusting seat, spring and the valve seat for having been loaded into filler and pushing block are sequentially loaded into valve inner, is reloaded into spheroid, adjusting seat, and then adjustable pretightning force between valve seat and spheroid are adjusted by specific purpose tool.
Description
Art
A kind of valve seat is the utility model is related to, more particularly to a kind of valve seat of ball valve.
Background technology
Upper-mounting type ball valve is widely used on oil and natural gas pipeline, and oil recovery, oil refining, petrochemical industry, chemical industry, chemical fibre, metallurgy,
In the devices such as electric power, nuclear power, food and papermaking, upper-mounting type ball valve dismantled on pipeline it is simple rapid, it is easy to maintenance quick, work as valve
Door is when failure needs to repair on pipeline, it is not necessary to valve is dismantled from pipeline, need only dismantle flange bolt and nut, by valve
Lid and valve rod group component are taken off from valve body together, then take out spheroid and valve seat combination part, you can it is online repair spheroid and
Valve seat, so maintenance saves the time, but existing ball valve adjusting means has some shortcomings：Initial tension of spring can not adjust and
Control, and amount of spring compression is big during assembling, and assembling is difficult.
Utility model content
To understand above mentioned problem of the prior art, the utility model offer is a kind of simple in construction, can there is adjustment pretightning force
Ball seat.
The utility model solves its technical problem the technical scheme adopted is that a kind of adjustable pre-tightening valve seat, including peace
Valve seat in valve body, it is arranged between valve seat and valve body by packing seal, filler by pushing block between valve seat and valve body
Packing cavity in, spring and adjusting seat are axially set gradually between pushing block and valve body, adjusting seat is fixed by screw thread and valve body, adjust
Bed rearrangement is axially movable the decrement of adjustment spring, and then adjusts the pretightning force between valve seat and spheroid.
The beneficial effects of the utility model are：During assembling, it is sequentially loaded into adjusting seat, spring in valve inner and has filled
Enter the valve seat of filler and pushing block, be reloaded into spheroid, adjusting seat is adjusted by specific purpose tool, and then can adjust between valve seat and spheroid
Pretightning force.
Brief description of the drawings
Fig. 1 is the structural representation of embodiment.
In figure：1. valve body；2. adjusting seat；3. spring；4. pushing block；5. filler；6. packing cavity；7. spheroid；8. valve seat.
Embodiment
As shown in figure 1, a kind of adjustable pre-tightening valve seat, including the valve seat 8 in valve body 1, valve seat 8 and valve body 1 it
Between sealed by filler 5, filler 5 is arranged in packing cavity 6 between valve seat 8 and valve body 1 by pushing block 4, pushing block 4 and valve body 1
Between axially set gradually spring and 3 adjusting seats 2, adjusting seat 2 is fixed by screw thread and valve body 1, and adjusting seat 2 is axially movable tune
The decrement of whole spring 3, and then adjust the pretightning force between valve seat 8 and spheroid 7.During assembling, tune is sequentially loaded into inside valve body 1
Bed rearrangement 2, spring 3 and the valve seat 8 for having been loaded into filler 5 and pushing block 4, are reloaded into spheroid 7, adjusting seat are adjusted by specific purpose tool
2, and then adjustable pretightning force between valve seat 8 and spheroid 7.
Claims (1)
1. a kind of adjustable pre-tightening valve seat, including the valve seat in valve body, pass through packing seal, institute between valve seat and valve body
Filler is stated to be arranged in the packing cavity between valve seat and valve body by pushing block, it is characterised in that:The countershaft of the pushing block and valve body
To spring and adjusting seat is set gradually, adjusting seat is fixed by screw thread and valve body, and adjusting seat is axially movable the pressure of adjustment spring
Contracting amount, and then adjust the pretightning force between valve seat and spheroid.
