Description
Technical field
The present invention relates to the technical field of sealing technology in pressure vessel, are specifically a kind of standing suitable for pressure vessel
Body sealing structure.
Background technology
The design of sealing structure is the pith of construction of pressure vessel design.Common seal form have forced seal and
Two kinds of forms of self-tightening sealing.The generally use forced seal structure in low, middle pressure pressure container, such as flange connection are special
Point is to generate gasket pretightning force by bolting on, and to reach initial sealing, when pressure rise, gasket can produce enough
Screen resilience and reach operation operating mode under sealability, self-energized seal commonly used in high-pressure bottle sealing structure in, but
Under high pressure operating mode, cause the service life of sealing element low, sealing performance is unreliable.Above-mentioned encapsulating method is current industrial general inclined use
Sealing structure, belong to flat seal mode（I.e. sealing direction pretightning force it is consistent with the air pressure Impact direction of the point or
On the contrary）.
With the diversified development of pressure vessel enlargement and application field, the thing followed is pressure vessel of quick opening door machine
The increase of structure diameter and the growth of length cause the opening of vessel that can also increase therewith, quick operating valve and sealing surface structure
Enlargement.Due to being influenced by mismachining tolerance and assembly precision, it may appear that the seal clearance between ontology and quick operating valve is uneven,
And existing sealing rubber ring its cross sectional shape is fixed, so it is difficult to adapt to non-uniform gap, therefore cause poor sealing.
To make up gap problem of non-uniform, general all take increases the method for sealing rubber ring sectional dimension to make up at present, but increases
Sealing rubber ring sectional dimension can make quick operating valve closure become very painstaking, or even will appear that quick operating valve cannot be closed completely show
As leading to part, there are gaps, serious to cause seal failure to can compress sealing rubber ring decrement, lead to nothing
Method reaches design requirement.Simultaneously as sealing rubber ring is squeezed for a long time, shape, which is fixed, follows the string, and causes poor sealing
A reason, the service life for sealing rubber ring occur is short, replaces with needing high-frequency.Therefore, for optimization pressure container
Sealing performance makes up the deficiency of existing flat seal mode, changes stress of the existing sealing rubber ring in seal process, carries
For a kind of novel sealing structure with excellent sealing effect, to meet the requirement of pressure vessel under high pressure.
