Abstract
The invention discloses a manhole structure of the inner container and the outer container of a low-temperature heat-insulation container. The outer container is arranged outside the inner container, a manhole connecting tube passes through the outer container to be communicated on the outer wall of the inner container, the openings of the manhole connecting tube are fastened with manhole covers through fastening pieces, one end of the manhole connecting tube, which is extended out of the outer container, is sheathed with an outer manhole connecting tube, the outer manhole connecting tube is welded on the outer wall of the outer container, the openings of the outer manhole connecting tube are fastened with outer manhole covers through outer manhole fastening pieces, and a heat-insulation filling is filled in a hollow cavity formed between the outer manhole connecting tube and the manhole connecting tube. In the manhole structure of the inner container and the outer container of the low-temperature heat-insulation container, disclosed by the invention, two manhole connecting tubes are adopted, the heat-insulation filling is arranged between the inner manhole connecting tube and the outer manhole connecting tube, the two manholes are respectively opened, in this way, the manhole in the inner container has operability, the maintenance is convenient, and in addition, the low-temperature sealing technology is adopted, so that the heat-insulation effect is suitable for the storage of a low-temperature liquid medium.
Description
Technical field
The invention belongs to the Cryo Heat Insulation pressurized container of storing liquid hydro carbons, liquified natural gas, liquid oxygen, liquid argon gas and liquid nitrogen, particularly the inside and outside container people hole structure of low temperature insulation container made.
Background technique
The manhole structure of inner container who is used for the Cryo Heat Insulation pressurized container of storing liquid hydro carbons, liquified natural gas, liquid oxygen, liquid argon gas and liquid nitrogen at present fixes; Can not opening operation; The manhole that is direct adopting process end socket and inner container is taken over welding; Total is arranged in the adiabatic space, only the manhole operating structure is set on outer container, though this structure guarantees leakproofness and insulation effect that inner container stores; But the manhole of inner container is full weldering fast knot structure, for later maintenance operation is made troubles.
Summary of the invention
The purpose of this invention is to provide a kind of can convenient for maintaining, container people hole structure inside and outside the low temperature insulation container made of adiabatic and good sealing effect.
For realizing above-mentioned purpose; Solution of the present invention is: the inside and outside container people hole structure of a kind of low temperature insulation container made; The meaningful device of inner container outer installment, said manhole are taken over and are passed the outer container connection on the outer wall of inner container, and the opening that said manhole is taken over is fastened with manhole cover through the manhole fastening piece; Said manhole is taken over an end outside of stretching out outer container and is with the adapter of stranger hole; Said outer manhole is taken over and is welded on the outer wall of outer container, and the opening that said outer manhole is taken over is fastened with outer manhole cover through outer manhole fastening piece, is filled with heat-insulating filler in the cavity that said outer manhole adapter and manhole form between taking over.
The inside and outside container people hole structure of above-mentioned low temperature insulation container made has adopted two manholes to take over; Inside and outside manhole is provided with thermal-protective material between taking over, and two manholes all can be opened, and the manhole that so just can solve inner container has operability; Made things convenient for maintenance; And adopting the low temperature seal technology, external insulation cold insulation, its insulation effect all can be applicable to the storage of low temperature liquid medium.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Embodiment
As shown in Figure 1; This invents the inside and outside container people hole structure of described low temperature insulation container made; The meaningful device 7 of inner container 8 outer installment, said manhole are taken over and are passed outer container 7 connections on the outer wall of inner container 8, and the opening of said manhole adapter 9 is fastened with manhole cover 10 through manhole fastening piece 9; Said manhole cover 10 bottoms are provided with manhole cover sealing gasket 11; The end outside that outer container 7 is stretched out in said manhole adapter 9 is with the stranger hole and takes over 5, and said outer manhole is taken over 5 and is welded on the outer wall of outer container 7, and the opening of said outer manhole adapter 5 is fastened with outer manhole cover 2 through outer manhole fastening piece 1; Said outer manhole cover 2 bottoms are provided with outer manhole cover sealing gasket 3, and said outer manhole adapter 5 and manhole are taken in the cavity that forms between 9 and be filled with heat-insulating filler 6.Said manhole take over 9 stretch out outer container 7 one section be provided with corrugated expansion joint 13; One end of said corrugated expansion joint 13 is welded on the end that outer container 7 ends are stretched out in manhole adapter 9; The other end is welded on the outer container 7, is provided with heat-insulating filler 15 in the cavity that forms between said outer container 7 and the inner container 8.
The present invention extends to the adapter of the inner container of Cryo Heat Insulation pressurized container outside the outer container; Take over inner container and be welded to connect; And in the adapter of part rational cold shrinkage-compensating device is set beyond the outer container; Compensate for shrinkage device expansion joint one end is welded on the end that stretches out of adapter, and the other end is welded on the outer container.Take over terminal flange and the blind flange of adopting as manhole; Calculate through the precooling amount; Confirm the thickness of flange gasket and the screw-down torque of bolt, pad is after the bolt on the last lower flange compresses, and it can seal the gap of lower flange; Solved the manhole structure behind the cryogenic media of packing into, the sealing effect of its whole fastening structure is very good.Calculate height and the external diameter of confirming that outer container is taken over through leaking heat; The manhole structure of whole contents device is covered, and lower end and outer container that outer container is taken over are welded to connect the upper end welded flange; Adopt flange arrangement to seal, fill suitable heat insulation material in the mezzanine space of formation.
