The technical solution of the utility model is：Automobile cylinder cover casting heating stalk structure, including stalk, described liter
It is cased with I extra set, II extra set, sleeve outside liquid pipe successively, between described I extra set, II extra set, form No. I chamber, described
Form No. II chamber, described II extra set is fixed with bearing phase, and described No. II chamber is provided with winding between II extra set, sleeve
Coil on No. II outer casing outer wall.
Described stalk upper end formation department of assembly, described I extra set upper side forms the shoulder hole accommodating department of assembly.
Described I extra set includes the upper snap ring of upper end and the lower snap ring of lower end, and described lower snap ring external diameter is less than outside upper snap ring
Footpath.
Described II extra set includes the ladder mounting ring of upper end and the retainer ring of lower end, described No. II outer casing internal diameter and lower card
Ring external diameter is identical, and the shoulder hole of described ladder mounting ring is identical with upper snap ring external diameter.

Room.
Described No. II outer casing outer wall, ladder mounting ring lower surface, retainer ring upper surface, sleeve lining enclose No. II chamber of formation
Room.
Described retainer ring end face forms through hole, and screw is fixed through above-mentioned through hole with bearing phase.
Described upper snap ring, ladder mounting ring are fixed by radial bolts, described sleeve and ladder mounting ring outer wall it
Between be interference fit.
This utility model reduces heat loss by No. I chamber between I extra set, II extra set, in No. II chamber
Coil can effectively avoid stalk to block, it is to avoid casting flaw, this utility model reduces energy consumption, improves production
Efficiency, improves the service life of stalk, is applicable in various air injection machines.
Brief description
