The positive effect of the utility model is: the upper-mounting type ball valve of the utility model can go out in valve line
When existing failure needs to repair, it is not necessary to valve is dismantled from pipeline, need only dismantle stud, nut, soket head cap screw, by valve deck and
Valve rod group component is taken off from valve body together, then takes out sphere and valve seat combination part repairs replacement, this maintenance section
The time has been saved, the loss in production has been bottomed out.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model preferred embodiment is provided, with reference to the accompanying drawing the technical solution of the utility model is described in detail.
As shown in Figure 1, the utility model upper-mounting type ball valve includes valve body 1, valve seat insert 2, valve seat 3, valve ball 4, retaining ring
5, bracing ring 6, spring 7, valve rod 8, thrust bearing 9, valve deck 10, sliding bearing 11, gasket 12, filler pressing sleeve 14, hold-down grid
15, stud 16, nut 17, soket head cap screw 18, valve ball 4 is equipped in valve body 1, and valve seat insert 2 is mounted on valve seat 3 and valve body 1
Between, retaining ring 5 is housed, valve seat insert 2 is lower to be equipped with bracing ring 6, and spring 7 is mounted on valve rod 8, and valve deck 10 is built-in on valve seat 3
There is thrust bearing 9, thrust bearing 9 is located at the side of sliding bearing 11, is equipped with filler 13, valve body 1 and valve deck in filler pressing sleeve 14
It is connected, is sealed between nut and valve deck by gasket 12, hold-down grid 15 passes through interior hexagonal by stud 16, nut 17 between 10
The threaded hole that screw 18 screws on valve deck 10 compresses filler pressing sleeve 14, is coupled by a square tenon between valve rod 8 and valve ball 4.
The spring is butterfly spring, adjusts valve ball and valve by butterfly spring self-deformation under worst hot case in this way
Thermal expansion deformation between seat, guarantees valve ball and valve seat is not in stuck phenomenon.
The lower edge shape of the retaining ring is wedge shape, the in this way convenient disassembly in valve on-bne repair, guarantees valve ball and valve seat
It is not in stuck phenomenon.
The top of the retaining ring is equipped with fabrication hole, preload in this way between valve ball and valve seat than pressure can by retaining ring come
It adjusts.
It is equipped with gasket between stud and nut, prevents from loosening in this way.
The working principle of the utility model is as follows: it is connected equipped with valve ball, valve body and valve deck by stud, nut in valve body,
Gasket seal is leaned among nut and valve deck, keeps the leakproofness between valve body and valve deck stronger, and valve deck is provided with thrust bearing, sliding
Bearing, filler, filler pressing sleeve, hold-down grid compress filler pressing sleeve by the threaded hole that soket head cap screw screws on valve deck, fill out
Expect that below pressing sleeve be filler, further enhances the leakproofness of ball valve in this way.Valve rod is coupled with valve ball by a square tenon, valve rod
It is fitted with a spring, guarantees valve ball and valve seat is not in stuck phenomenon.There are a valve seat insert, valve seat below valve ball
Sealing ring is mounted between valve seat and valve body, has a bracing ring below valve seat insert, can have under worst hot case in this way
Effect slows down valve ball extruding caused by valve seat due to thermal expansion deformation, can preferably extend the service life of workpiece.Sliding
Bearing is used to that valve rod is assisted to rotate, and can greatly reduce the surface abrasion between the valve ball and valve seat that valve rod rotation drives, valve body
It is connected with valve deck by stud, nut, after back-out stud, nut remove valve deck, just can dismantle thrust bearing, the cunning of valve inner
Dynamic bearing and filler can carry out on-bne repair, and need only dismantle stud, nut, soket head cap screw, by valve deck and valve rod group component
It is taken off from valve body together, then takes out sphere and valve seat combination part repairs replacement, this maintenance saves the time, will
Loss in production bottoms out.Valve is one-way flow, and when rotary valve rod counterclockwise, valve rod drives valve ball to rotate nine together
At ten degree, ball valve is closed, on-bne repair convenient disassembly, sealed reliable, long service life.
In conclusion the utility model upper-mounting type ball valve can be when failure needs to repair in valve line, it is not necessary to
Valve is dismantled from pipeline, need only dismantle stud, nut, soket head cap screw, by valve deck and valve rod group component together from valve body
It takes off, then takes out sphere and valve seat combination part repairs replacement, this maintenance saves the time, by the loss in production
It bottoms out.
Particular embodiments described above, the technical issues of to the solution of the utility model, technical scheme and beneficial effects
