Abstract
The utility model relates to a kind of sealing configuration of pressurized container, comprise pressure container cylinder end, described barrel end is provided with flat cover, described flat cover is provided with couble-cone seal ring with coordinating between barrel end, the outer rim annular space of described flat cover is sheathed on barrel end periphery, described couble-cone seal ring is arranged in the annular space of flat cover outer rim and barrel end, the upper and lower end of described couble-cone seal ring is respectively equipped with the contrary interior sealing cone of taper direction, coordinates respectively and be provided with the conical surface be sealed and matched with interior sealing cone between described flat cover and barrel end.The sealing configuration of pressurized container of the present utility model, reasonable in design, sealing is reliable.
Description
Technical field
The utility model relates to a kind of sealing configuration of pressurized container, for the sealing of pressure container cylinder and cap.
Background technique
The design of sealing configuration is the pith of construction of pressure vessel design.Common seal form has forced seal and self-tightening sealing two kinds of forms.
Usually forced seal structure is adopted in low, middle pressure pressure container, as flanged connecting structure, be characterized in that dependence is bolted on and produce pad pretightening force, thus reach initial sealing, when pressure raises, pad can produce enough spring-back forces and reach operation operating mode under sealability.Self-energized seal is generally used in the sealing configuration of high-pressure bottle, but under high pressure operating mode, the life-span of Sealing is low, and sealability is unreliable.
Model utility content
The utility model, for prior art Problems existing, provides the sealing configuration that a kind of structure is simple, reasonable in design, seal reliable a kind of force container.
The purpose of this utility model realizes like this, a kind of sealing configuration of pressurized container, comprise pressure container cylinder end, described barrel end is provided with flat cover, described flat cover is provided with couble-cone seal ring with coordinating between barrel end, the outer rim annular space of described flat cover is sheathed on barrel end periphery, described couble-cone seal ring is arranged in the annular space of flat cover outer rim and barrel end, the upper and lower end of described couble-cone seal ring is respectively equipped with the contrary interior sealing cone of taper direction, coordinates respectively and be provided with the conical surface be sealed and matched with interior sealing cone between described flat cover and barrel end.
The sealing configuration of pressurized container of the present utility model, due to the two-way conical surface sealing structure adopting direction contrary, when stud pretension flat cover and cylindrical shell, make when pretightening force reaches the prefastening load of couble-cone seal ring couble-cone seal ring produce lateral extrusion distortion and form initial sealing, when operating the container inner pressure under operating mode and rising, because stud is stretching trend, thus the axial spring-back force making pad produce has the trend of reduction, radial direction is due to pressure effect, produce the trend that inwardly reduces, two reverse sealing cones can still fit tightly and reach better sealing.Therefore seal with double-cone structure of the present utility model is simple, reasonable in design, and sealing is reliable.
For improving sealability further, the cooperation conical surface of described couble-cone seal ring covers flexible graphite belt.
For realizing reliable sealing further, the sealing cone of described couble-cone seal ring becomes 20 ° ~ 30 ° angles with the thick direction of ring.
For ease of the stabilized seal of practical couble-cone seal ring, described couble-cone seal ring is arranged with in flat cover, the cone match of upper end and flat cover, lower end periphery by with the fixing ring washer of flat cover lower end periphery screw against fixing.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the sealing configuration of pressurized container of the present utility model.
Wherein, 1 barrel end, 2 graphite tapes, 3 couble-cone seal rings, 4 flat covers, 5 ring washers.
Embodiment
As the sealing configuration that Fig. 1 is pressurized container of the present utility model, comprise pressure container cylinder end 1, barrel end 1 is provided with flat cover 4, coordinate between flat cover 4 with barrel end 1 and be provided with couble-cone seal ring 3, the outer rim annular space of flat cover 4 is sheathed on barrel end 1 periphery, couble-cone seal ring 3 is arranged in the annular space of flat cover 4 outer rim and barrel end 1, the upper and lower end of couble-cone seal ring 3 is respectively equipped with the contrary interior sealing cone of taper direction, coordinates respectively and be provided with the conical surface be sealed and matched with interior sealing cone between flat cover 4 and barrel end 1; The cooperation conical surface of couble-cone seal ring 3 covers flexible graphite belt 2; The sealing cone of couble-cone seal ring 3 becomes 20 ° ~ 30 ° angles with the thick direction of ring; Couble-cone seal ring 3 is arranged with in flat cover 4, the cone match of upper end and flat cover 4, lower end periphery by with the fixing ring washer 5 of flat cover 4 lower end periphery screw against fixing.
The sealing configuration of pressurized container of the present utility model, due to the two-way conical surface sealing structure adopting direction contrary, when stud pretension flat cover 4 and cylindrical shell, make when pretightening force reaches the prefastening load of couble-cone seal ring 3 couble-cone seal ring 4 produce lateral extrusion distortion and form initial sealing, when operating the container inner pressure under operating mode and rising, because stud is stretching trend, thus the axial spring-back force making couble-cone seal ring 3 produce has the trend of reduction, radial direction is due to pressure effect, produce the trend inwardly reduced, two reverse sealing cones can still fit tightly and reach better sealing.Therefore seal with double-cone structure of the present utility model is simple, reasonable in design, and sealing is reliable.
