The purpose of this utility model is to overcome shortcoming present in prior art to provide a kind of simple in construction, sealing effectiveness
Stable oil well cement high temperature high-pressure curing kettle kettle cover sealing structure.
To achieve these goals, the utility model provides following technical scheme：
A kind of oil well cement high temperature high-pressure curing kettle kettle cover sealing structure, it includes kettle cover and kettle core, the kettle core insertion
In the kettle cover, couble-cone seal ring is provided with the kettle core, it is characterized in that, it is additionally provided with the lower end periphery of the kettle core
V-seal cushion rubber and O-shaped O-ring seal are provided with annular receiving groove, the annular receiving groove, the O-shaped O-ring seal is installed
In the V-groove of the V-seal cushion rubber.
Further, wherein, the V-seal cushion rubber and O-shaped O-ring seal are all made up of flexible fluorine material.
Further, wherein, the top of the kettle core stretched out from the top of the kettle cover and by nuts and washers with
The kettle cover is fixed together.
Yet further, wherein, be additionally provided with handle on the kettle cover.
Again further, wherein, be additionally provided with handle on the kettle cover.
Compared with existing curing autoclave kettle cover sealing device, oil well cement high temperature high-pressure curing kettle kettle cover of the present utility model
Sealing structure has following advantageous effects：It is installed to using the kettle cover composition of sealing structure of the present utility model on kettle,
After kettle water inlet, kettle core, couble-cone seal ring, kettle cover is set to produce self-pressure-sealed, the fluorine material sealing ring on kettle core by hydraulic pressure
Combination is in close contact with inner wall of kettle, prevents water from being overflowed from kettle cover screw thread, and sealing ring combination can be with pressure-bearing 0-40Mpa, kettle cover
Installation operation is simple, good sealing effect.
