Description

A kind of double-decker pressure vessel bushing device and method
Technical field
The present invention relates to a kind of pressure vessel bushing device and method, belong to pressure vessel field, and in particular to Yi Zhongshuan Rotating fields pressure vessel bushing device and method.
Background technology
Natural gas pressure vessel of the prior art, such as storage tank, tank case and tank car, its structure are tied to be double-deck Structure, internal layer is generally stainless steel inner pressurd vessel, and for depositing liquefied natural gas, outer layer is carbon steel or stainless steel casing.Ectonexine Between be vacuum layer, typically after evacuation carry out heat-insulating material lay or pearlife filling.
Due to inner pressurd vessel and shell axiality require it is higher, therefore inner pressurd vessel with outer cover suit when typically use it is special Bushing device, inner pressurd vessel and shell could be fitted together.
It is set with prior art using suit tire, it is by two sets of inner pressurd vessel support meanss and housing roller frame Device is constituted.Suit tire suit scheme be:
1) shell is placed on turning rolls, then starts turning rolls and move ahead, the shell level on turning rolls is penetrated into set The suit arm of tire is closed, and is moved to appropriate position.
2) inner pressurd vessel is placed in the support meanss of inner pressurd vessel, then moved shell in the opposite direction, start into The interference between moment attentinal contents device and shell is answered during the suit of row inner pressurd vessel and shell, suit.
3) suit of inner pressurd vessel and shell is completed, passes through the horizontal and vertical movement of support meanss, it is ensured that inner pressurd vessel and outer The Barrel alignment deviation of shell is within the scope of product requirement.
Although existing suit tire can have the shortcomings that following aspect with many products of fit:
1) it is less than 2000mm pressure vessel for external diameter, because suit arm appearance and size is larger, shell can not penetrate set Arm is filled, therefore set reload request can not be met;
2) for the vertical double structural pressure container filled using pearlife, under inner pressurd vessel is required in structure and be outer End socket group postwelding could be set with.To ensure the depth of parallelism of supporting leg bottom surface and outer low head, typically by supporting leg and outer lower envelope Head group is set with after being welded into one.Because leg length is longer, tunica dress tire can not be set with.
It is to solve the less pressure vessel of diameter and pearlife vertical storage tank due to the presence of disadvantage mentioned above, in production Suit is, it is necessary to design and manufacture special bushing device, the need for meeting actual pressure container production.
The content of the invention
The tunica dress tire that the present invention mainly solves present in prior art can not be set with the pressure that external diameter is less than 2000mm There is provided one kind for the problem of container and the vertical double structural pressure container of pearlife filling can not be set with using tunica dress tire Double-decker pressure vessel bushing device and method.
