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 low-temperature heat-insulation pressure 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 at present the low-temperature heat-insulation pressure container of storing liquid hydro carbons, liquified natural gas, liquid oxygen, liquid argon gas and liquid nitrogen fixes, can not opening operation, it is the manhole connecting pipe welding of direct adopting process end socket and inner container, total is arranged in the adiabatic space, only at outer container the manhole operating structure is set, although this structure guarantees leakproofness and insulation effect that inner container stores, but the manhole of inner container is for entirely being welded 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 achieving the above object, 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, described manhole connecting pipe passes outer container and is communicated with on the outer wall of inner container, the opening of described manhole connecting pipe is fastened with manhole cover by the manhole fastening piece, the end outer cover that described manhole connecting pipe stretches out outer container has outer manhole to take over, described outer manhole is taken over and is welded on the outer wall of outer container, the opening that described outer manhole is taken over is fastened with outer manhole cover by outer manhole fastening piece, is filled with heat-insulating filler in the cavity that forms between described outer manhole adapter and the manhole connecting pipe.
The inside and outside container people hole structure of above-mentioned low temperature insulation container made has adopted two manhole connecting pipes, be provided with thermal-protective material between the inside and outside manhole connecting pipe, two manholes all can be opened, 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, described manhole connecting pipe passes outer container 7 and is communicated with on the outer wall of inner container 8, the opening of described manhole connecting pipe 9 is fastened with manhole cover 10 by manhole fastening piece 9, described manhole cover 10 bottoms are provided with manhole cover sealing gasket 11, the end outer cover that described manhole connecting pipe 9 stretches out outer container 7 has outer manhole to take over 5, described outer manhole is taken over 5 and is welded on the outer wall of outer container 7, the opening of described outer manhole adapter 5 is fastened with outer manhole cover 2 by outer manhole fastening piece 1, described outer manhole cover 2 bottoms are provided with outer manhole cover sealing gasket 3, are filled with heat-insulating filler 6 in the cavity that forms between described outer manhole adapter 5 and the manhole connecting pipe 9.Described manhole connecting pipe 9 stretches out a section of outer container 7 and is provided with corrugated expansion joint 13, one end of described corrugated expansion joint 13 is welded on the end that manhole connecting pipe 9 stretches out outer container 7 ends, the other end is welded on the outer container 7, is provided with heat-insulating filler 15 in the cavity that forms between described outer container 7 and the inner container 8.
The present invention extends to the adapter of the inner container of low-temperature heat-insulation pressure container outside the outer container, take over inner container and be welded to connect, and the adapter of part arranges rational cold shrinkage compensating device beyond 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 pre-cold, determine the thickness of flange gasket and the screw-down torque of bolt, pad is after the bolt on the upper lower flange compresses, 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.Height and the external diameter taken over by leaking hot calculative determination outer container, the manhole structure of whole inner container 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.
