Description
Technical field
The utility model belongs to mounting tool, and in particular to a kind of small-bore upper-mounting type ball valve valve seat mounting tool.
Background technique
Small-bore upper-mounting type ball valve its valve chamber and flow channel space it is less than normal, it is compact-sized etc. due to, cause machine assembly
Valve seat can not be applied in the process and overcome the pretightning force of disc spring and then valve seat can not be made to reach valve body designated mounting position,
In view of the foregoing, how using existing valve mechanism, under the premise of space, carry out the research of valve seat mounting process at
The matter of utmost importance faced for small-bore upper-mounting type ball valve machine assembly.
Utility model content
The utility model in view of the drawbacks of the prior art, provides a kind of small-bore upper-mounting type ball valve valve seat mounting tool.
The technical solution of the utility model is: a kind of small-bore upper-mounting type ball valve valve seat mounting tool, wherein including expansion sleeve,
Expansion sleeve is hollow cylindrical component, and setting is similarly the swelling screw rod of hollow circle tube among expansion sleeve, in swelling spiral shell
Expanding mandrel is set in bar, swelling nut is set in the front end of expansion sleeve, tightening nut is socketed outside expansion sleeve.
A kind of small-bore upper-mounting type ball valve valve seat mounting tool as described above, wherein be arranged in swelling nut rear and grind
Scrubbing pad piece.
A kind of small-bore upper-mounting type ball valve valve seat mounting tool as described above, wherein be also socketed on the expansion sleeve
Adjust gasket.
A kind of small-bore upper-mounting type ball valve valve seat mounting tool as described above, wherein the expansion sleeve outer cross section is
Hexagonal structure.
A kind of small-bore upper-mounting type ball valve valve seat mounting tool as described above, wherein be equipped in the middle part of the expansion sleeve
Locating shoulder.
The effect of the utility model is: (1) clever structure, easily operated.Due to using combination unit structure, clever structure is whole
Body weight is lighter, is easily installed personnel's carrying.Expansion set has automatic and valve seat positioning centering function simultaneously, to realize the present apparatus
Fast Installation when use.(2) tooling versatility is stronger.Since expansion set has certain elasticity, while expansion set and expanding mandrel cooperate
Using taper fit, can be realized the swelling of this tooling in a certain range by tensing expanding mandrel, thus this tooling have compared with
Strong versatility.(3) operator's working strength is reduced, working efficiency is improved.For reduce during swelling nut and part it
Between frictional force, increasing friction gasket between nut and part respectively and playing reduces operator's working strength, while improving work
Make efficiency.

Specific embodiment
This patent is further illustrated with reference to the accompanying drawing:
4 elastic grooves are opened in 3 left part of expansion sleeve as shown in Figure 1 and Figure 2, so that expansion sleeve has elasticity.To make expansion sleeve
3 can provide and be wrenched reaction force, be equipped with outer-hexagonal structure in its right part.Fast and easy installation simultaneously, sets in the middle part of expansion sleeve 3
There is locating shoulder.Swelling nut 7 is connected using taper fit between expanding mandrel 1 and expansion sleeve 3, while using swelling screw rod 2,
One is made, by screwing swelling nut 7, under 2 pulling force effect of swelling screw rod, 3 left side branch of expansion sleeve can be realized
Foot opens, to realize swelling function.
To guarantee present apparatus service life for a long time and nut is wrenched intensity, respectively tightening nut 5 and part to be installed it
Between increase adjustment gasket 4, between swelling nut 7 and expansion sleeve 3 increase friction gasket 6, avoid frictional force occur in the process of being wrenched
Excessive the case where leading to Caton generation.
As shown in Figure 4, Figure 5, after valve seat 8 and disc spring 9 first being pre-installed supreme 10 inner hole of dress formula valve body, then by present apparatus list
Member is packed into predetermined position by upper 10 right end face of dress formula valve body, using 3 locating shoulder of expansion sleeve and upper 10 inner hole of dress formula valve body
It is positioned, guarantees that the present apparatus and valve seat 8 are concentric, after the installation is completed, expansion sleeve 3 is fixed with spanner 11, by screwing swelling spiral shell
Female 7 (forming reaction force between spanner 11), open in 3 stabilizer blade of expansion sleeve to 8 slot of valve seat and block valve seat 8, then screw
Tightening nut 5 (forms reaction force between spanner 11), keeps present apparatus side direction of turning right mobile, to precisely smoothly drive
Valve seat 8 overcomes 9 pretightning force of disc spring to designated position, after remaining good Assembly part to be installed, unclamps swelling nut 7, that is, can be taken off
The present apparatus quickly finishes a valve seat installation.
