Description
Technical field
The present invention relates to the technical field of sealing technology in pressure vessel, are specifically a kind of filling suitable for pressure vessel
Airtight closure door.
Background technique
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.Forced seal structure, such as flange connection are generallyd use in low, middle pressure pressure container, it is special
Point is to generate gasket pretightning force by bolting on, to reach initial sealing, when pressure rise, gasket can produce enough
Screen resilience and reach operation operating condition under sealability, self-energized seal commonly used in high-pressure bottle sealing structure in, but
Under high pressure operating condition, cause the service life of sealing element low, sealing performance is unreliable.It is more with pressure vessel enlargement and application field
Sampleization development, consequent is the increase of the door body mechanism diameter of pressure vessel and the growth of length, leads to vessel
The access way gate opened up can also increase with it, and door body and sealing surface structure are also enlarged.Due to by mismachining tolerance and assembly
The influence of precision, it may appear that the seal clearance between ontology and door body is uneven, and existing sealing rubber ring its cross sectional shape is
Fixed, so being difficult to adapt to non-uniform gap, therefore cause poor sealing.
It is well known that hermatic door is in every profession and trade using being extremely extensive.Currently, traditional hermatic door generally all includes
One group of vertical edges of door-plate and doorframe, door-plate and doorframe are hinged, have locking in another group of vertical edges of door-plate and doorframe
Device has sealing strip at the position opposite with door-plate on doorframe, has handle on the vertical edge of door-plate non-articulated.This hermatic door by
In carrying out a fixing seal only with the locking device on one group of butt joint edge on doorframe and door-plate, so its sealing effect ratio
It is poor, it only can be used in the place not high to seal request, and this hermatic door automates journey using manually being opened
It spends low.
Therefore, in order to optimize the sealing performance of large pressurized vessel, the deficiency of existing hermatic door is made up, existing sealing is changed
Stress of the cushion rubber in seal process provides a kind of sealing door body structure with excellent sealing effect, to meet pressure
