The utility model content
The purpose of this utility model is to solve under the kettle cover that has high temperature and high pressure kettle now and the corrosion test operating mode that the kettle sealing surface is in HTHP for a long time, can produce darker plastic deformation impression and affect the problem of test sealing again, a kind of structure for kettle sealing surface service life of extending high temperature and high pressure kettle is provided, its plastic deformation under HTHP is little, and can there is good durability and reliability
The purpose of this utility model is achieved through the following technical solutions: a kind of structure for kettle sealing surface service life of extending high temperature and high pressure kettle, comprise kettle and the kettle cover be connected with kettle, described kettle upper end open, kettle sidewall top is provided with the nickel-base alloy band around the kettle upper end open, and described kettle cover forms the sealing sphere contacted with the nickel-base alloy band.Kettle cover of the present utility model is with after kettle is connected, and the sealing sphere of kettle cover contacts with the nickel-base alloy band and forms sealing contact surface, and then guarantees the sealing of kettle cover to the kettle upper end open.
Described kettle sidewall top forms the annular slope around the kettle upper end open, and described annular slope upper surface indent forms the endless groove around the kettle upper end open, and described nickel-base alloy band embeds in this endless groove.The utility model, by the nickel-base alloy band is arranged in endless groove, is convenient to arrange the nickel-base alloy band on kettle.And make the syndeton between nickel-base alloy band and kettle more firm.
Described nickel-base alloy band and endless groove size shape coupling.The utility model is by the nickel-base alloy band being arranged to and the structure of endless groove size coupling, and so, nickel-base alloy band upper surface is concordant with the annular slope of kettle, can reduce colliding with of kettle cover and nickel-base alloy band while filling/opening still.
Described kettle and kettle cover are bolted connection, and the end that described bolt is positioned at kettle cover is by fastening nuts, and it is fastening by flange that described bolt is positioned at an end of kettle.Wherein, kettle and kettle cover are bolted, and fastening by nut and flange, easy installation and removal.
The wearing and tearing that while in order to reduce, screwing nut, nut causes kettle cover, be provided with the packing ring be set on bolt between described kettle cover and nut.
Compared with prior art, the utlity model has following beneficial effect: the utility model comprises kettle and the kettle cover be connected with kettle, the kettle sidewall is connected with the nickel-base alloy band contacted with kettle cover sealing ball face sealing, the utility model overall structure is simple, be convenient to realize, wherein, the deformation of nickel-base alloy band impression is little, durability and the reliability of sealing surface opposing pressurization/decompression stress while repeatedly filling/opening still have been increased, can improve the sealing property of high temperature and high pressure kettle, to adapt to the operating mode of nuclear material out-pile long-term corrosion performance test, can extend kettle service life simultaneously.
