Further, the step surface is equal to described around the diameter that the revolution of the axle center of seat ring ontology is formed by cylindrical chamber
Die casting inclined-plane is formed by the maximum gauge of cone-shaped cavity around the revolution of the axle center of seat ring ontology.
Further, the demoulding cylinder is equal to institute around the diameter that the revolution of the axle center of seat ring ontology is formed by cylindrical chamber
State the minimum diameter that die casting inclined-plane is formed by cone-shaped cavity around the revolution of the axle center of seat ring ontology.
Further, the height of the step surface is 2mm~2.5mm.
Further, the seat ring ontology periphery is equipped at least one circle annular protrusion.
Further, the annular protrusion along the band one end arc convex and extend.
Further, the outer rim on the seat ring ontology close to demoulding cylinder one end is additionally provided with chamfering.
Beneficial effect
Compared with prior art, the present invention having the advantage that
1, Novel valve seat ring of the invention, simple structure and convenient processing, without processing secondary surface on valve retainer,
The quantity for reducing dedicated tool, saves process time, has the characteristics that process velocity is fast, at low cost, easy for installation；
2, the present invention is by the periphery setting annular protrusion in seat ring ontology, with improve valve retainer and engine cylinder cover it
Between frictional force, the problem of effectivelying prevent valve retainer to loosen；
3, the present invention is by being arranged chamfering in one end of seat ring ontology, and sets annular protrusion to towards sealed end one end arc
Structure shape protrusion and extended, convenient in valve retainer indentation engine cylinder cover.
Detailed description of the invention
Fig. 1 is the schematic diagram of the section structure of the prior art；
Fig. 2 is the schematic diagram of the section structure of the invention.
Wherein: 1- seat ring ontology, 2- band, 3- die casting inclined-plane, 4- step surface, 5- demoulding cylinder, 6- annular protrusion,
Supplemental slanted surface under the upper supplemental slanted surface of 7- chamfering, 8-, 9-.
Specific embodiment
The present invention is described further for specific embodiment in reference to the accompanying drawing.
As shown in fig.2, a kind of new structural valve retainer of the invention, including seat ring ontology 1, in seat ring ontology 1
One end is equipped with band 2, is equipped with die casting inclined-plane 3 in 1 other end of seat ring ontology, is equipped between die casting inclined-plane 3 and band 2
One step surface 4 arranged vertically, wherein the both ends of step surface 4 are connected with the linking of one end of die casting inclined-plane 3, band 2 respectively,
A demoulding cylinder 5 arranged vertically, demoulding cylinder 5 and die casting inclined-plane are additionally provided on the seat ring ontology 1 of 3 lateral ends of die casting inclined-plane
