Cause link block dislocation.
As the technical solution of optimization, the inner ring of each link block (11) is equipped with several monodentates (14), each monodentate (14)
Form labyrinth seal structure.Using labyrinth seal structure, fluid is by many throttle clearances and expands the logical of cavity composition
Road generates very big flow loss by repeatedly throttling, and fluid head greatly declines, and fluid is made to be difficult to leak, and improves close
Seal effect.
As the technical solution of optimization, the elastomer (2) is the elastic ring covered in the outer ring of the retaining ring (1).Pass through
Retaining ring is locked in the contraction of elastic ring.
As the technical solution of optimization, the body (2) includes several flexible connectors, and each flexible connector is connected to
On each link block (11).Make the centripetal movement of each link block by each flexible connector, to lock retaining ring.
It further include elastic sealing element (3) as the technical solution of optimization, the elastic sealing element (3) is located at the retaining ring
(1) one of end face.Elastic sealing element is used as end face seal, improves sealing effect.
As the technical solution of optimization, the elastic sealing element (3) uses several O-rings, and wherein the one of the retaining ring (1)
A end face is equipped with several circle concentric circles annular grooves (15), and each elastic sealing element (3) is respectively provided in each annular groove (15).
The present invention has the advantages that
1, it creatively proposes with flexible restraint restraint rigidity wearing piece, and compensation stiffer wear-resistant part is using automatically
The abrasion of middle generation makes to obtain better seal between rigid seal and workpiece；Also solve flexible seals in spy simultaneously
The problem that situations such as such as high temperature can not seal under kind environment and service life is short.
2, elastomer can lock retaining ring, form compensation mechanism, sealing effect is good, and it is steady to be conducive to pressure in molten tin bath
Determine and reduce the oxidation of N2, H2 gas usage and tin liquor.
3, when retaining ring inner ring abrasion when, elastomer can constantly lock keep inner ring sealing until retaining ring it is completely worn out,
The replacement cycle that retaining ring can be extended reduces the replacement frequency of retaining ring, saves production cost.
4, retaining ring is made of wear-resisting lubriation material, and lubricity is good, it is possible to reduce the friction between retaining ring and drawing side rod is prolonged
The long service life for drawing side rod.
5, using labyrinth seal structure, sealing effect is improved.
6, elastic sealing element is used as end face seal, improves sealing effect.
