Technical field
The present invention relates to a kind of low-temperature storage tank improving vacuum pumping device installation sealing.
Background technique
Universal along with expanding economy and cryogenic technique, the application of the cryogenic liquides such as liquid nitrogen, liquid oxygen, liquefied ammonia, liquid hydrogen and LNG Liquefied natural gas is increasingly extensive, all trades and professions are to store and the demand of low-temperature (low temperature) vessel of transporting low temperature liquid constantly increases, and the safety issue of low-temperature (low temperature) vessel in transportation process can not be ignored.
Low-temperature storage tank mainly contains inside and outside double-layer structure composition, for improving the thermal insulation property of storage tank entirety, interlayer is needed to vacuumize, in the past because the sealability between the pipeline for vacuumizing and outer cylinder body is undesirable, interlayer between inside and outside cylindrical shell easily infiltrates air, thus reduces the thermal insulation property of storage tank and the heat-shielding performance of entirety.
Summary of the invention
The invention provides a kind of low-temperature storage tank improving vacuum pumping device installation sealing.
The technical solution adopted in the present invention is to achieve the above object of the invention: a kind of low-temperature storage tank improving vacuum pumping device installation sealing, comprise outer cylinder body and inner barrel, described outer cylinder body and inner barrel form adiabatic space, outer left envelope and outer right envelope is respectively equipped with at the two ends of described outer cylinder body, described outer cylinder body is provided with vacuum pumping device, and the suction pipe of this vacuum pumping device to stretch in adiabatic space and form close fit between outer cylinder body;
The suction pipe being positioned at outer cylinder body outside forms external thread section and outer nut is set on this external thread section, the suction pipe being positioned at adiabatic space forms external thread section and inner nut is set on this external thread section, suction pipe is fixed on outer cylinder body by two nut, suction pipe between outer nut and outer cylinder body is provided with groove lid, the groove cylindrical shell setting toward the outside of groove lid, is provided with silica gel sealing glue in the groove of groove lid.
Further, described vacuum pumping device is also provided with safety cover outward, and this safety cover is connected with outer cylinder body.
Further, the suction pipe being positioned at outer cylinder body outside is tilted to lower setting.
Further, pearlife is filled up in the interlayer between described outer cylinder body and described inner barrel.

Embodiment
As shown in Figure 1 shown in Fig. 2, the technical solution adopted in the present invention is to achieve the above object of the invention: a kind of low-temperature storage tank improving vacuum pumping device installation sealing, comprise outer cylinder body 2 and inner barrel 1, outer cylinder body 2 and inner barrel 1 form adiabatic space, outer left envelope and outer right envelope is respectively equipped with at the two ends of outer cylinder body 2, outer cylinder body 2 is provided with vacuum pumping device 3, the suction pipe 4 of this vacuum pumping device 3 to stretch in adiabatic space and form close fit between outer cylinder body 2.
The suction pipe 4 being positioned at outer cylinder body 2 outside forms external thread section and outer nut 5 is set on this external thread section, the suction pipe 4 being positioned at adiabatic space forms external thread section and inner nut 6 is set on this external thread section, suction pipe 4 is fixed on outer cylinder body 2 by two nut, suction pipe 4 between outer nut 5 and outer cylinder body 2 is provided with groove lid 7, the groove of groove lid 7 toward the outside cylindrical shell 2 is arranged, and is provided with silica gel sealing glue 8 in the groove of groove lid 7.Groove lid 7 is combined on the outer wall of outer cylinder body 2 through the active force sealing paste of outer nut 5.
Vacuum pumping device 3 is outer is also provided with safety cover 9, and this safety cover 9 is connected with outer cylinder body 2.The suction pipe 4 being positioned at outer cylinder body 2 outside is tilted to lower setting.Pearlife is filled up in interlayer between outer cylinder body 2 and inner barrel 1.Because the capacity of heat transmission of pearlife is poor, the effect of heat insulation thermal insulation after exhausting vacuum, can be reached.
Rely on the ductility of silica gel sealing glue 8, can infiltrate in the gap between suction pipe 4 and outer cylinder body 2, when in insulated space for vacuum state time, if there is gap, can silica gel sealing glue 8 be inhaled in this gap, improve the sealability of adiabatic space, thus improve the Cryo Heat Insulation performance of whole storage tank.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just design according to the present invention can make many modifications and variations without the need to creative work.Therefore, all technician in the art on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment, all should fall within the scope of protection of the present invention under this invention's idea.
