By using technique scheme: when spheroid is full opening of state, the second locating piece embeds in open slot,
Now, spring steel ball snaps in groove, arranges spring steel ball, can keep the abutting shape of the first locating piece and the second locating piece
State, so can avoid maloperation, cause valve rod to rotate, and improves ball valve reliability in the course of the work.
It is also preferred that the left the outer surface of described spheroid is provided with wearing layer.
By using technique scheme: arrange wearing layer, the anti-wear performance of spheroid can be improved, extend making of spheroid
Use the life-span.
It is also preferred that the left described wearing layer is nanometer Al2O3Transparent wear composite coating layer.
By using technique scheme: nanometer Al2O3Transparent wear composite coating be the anti-wear performance being currently known very
Excellent wear-resistant paint, anti-wear performance is excellent, and stable chemical nature, adhesive force is good.
In sum, this utility model has the advantages that
1, abrasion is cushion block, after cushion block weares and teares, it is only necessary to replaced by cushion block, changes new cushion block i.e.
Can, now due to spheroid not by any damage, therefore, spheroid remains able to normally use, and extends the use longevity of spheroid
Life.
2, cushion block can use rubber to make, owing to elastomeric material has certain flexibility, and hence it is also possible to play certain
Pooling feature, also be able to valve rod play certain protection, reduce the abrasion of valve rod.
