Lid includes：Cylinder head, is provided with water hole, cooling hole, exhaust duct, water jacket and multiple exhaust valve seat collar aperture, and exhaust duct connects
Lead to exhaust valve seat collar aperture, the first circumferential groove is provided on the inner wall of exhaust valve seat collar aperture, the first groove is connected to water jacket, is arranged
Exhaust valve seat insert is installed, exhaust valve seat insert offers and the towards circumferential direction on the outer wall of exhaust valve seat collar aperture in valve retainer hole
The second groove that one groove is oppositely arranged offers third groove on the slot bottom of the second groove, and the slot bottom of third groove offers
The recessed joint of invagination, multilayered fold is provided on the inner wall of exhaust valve seat insert, and recessed joint is arranged towards the protruding parts of fold.
Wherein, the first groove between exhaust valve seat collar aperture and exhaust valve seat insert, the second groove, third groove and recessed joint
Between enclose and set a circle and form the cooling chamber that is connected to water jacket.
Wherein, it is connected by channel between the cooling chamber of two adjacent exhaust valve seat inserts.
Wherein, upper water hole is connected to cooling hole, and cooling hole is connected to cooling chamber.
Implement the utility model embodiment, has the advantages that：A kind of novel cylinder cover of the utility model, passes through
The multiple grooves and recessed joint stretched into seat ring side wall being arranged on exhaust valve seat ring outer wall, and the pleat that is arranged on inner wall
Wrinkle, not only effectively raises the cooling-down effect to exhaust valve seat insert, but also can effectively reduce high temperature and high pressure gas to exhaust
The impact injury of seat ring inner wall, prolongs the service life.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
