Detailed Description
For the purpose of further illustrating the principles and structure of the present invention, preferred embodiments of the invention will now be described in detail with reference to the accompanying drawings.
The invention provides a low-temperature pressure container, which comprises a tank body, a gas phase pipeline and a heat insulation fixing device for connecting the gas phase pipeline and the tank body. The heat insulation fixing device can be used for a single-layer low-temperature pressure container and a double-layer low-temperature pressure container.
The invention is described in terms of a dual-layer low temperature pressure vessel as an adiabatic fixing device of the invention.
Fig. 2 is a schematic structural view of the low-temperature pressure vessel of the present invention, and fig. 3 is a partial schematic view of the low-temperature pressure vessel of the present invention, as shown in fig. 2 and 3. As shown in fig. 2, the low-temperature pressure vessel 20 includes an inner tank 22 (i.e., tank) and an outer tank 21, and a gas-phase pipe 23 is disposed between the inner tank 22 and the outer tank 21. The gas phase pipe 23 is connected with a gas phase interface 26 on the inner tank 22. Expanded perlite 25 for heat preservation and insulation is also arranged between the inner tank 22 and the outer tank 21. The heat insulating fixture 24 is not shown in fig. 2.
As shown in fig. 3, the gas phase pipe 23 is fixed to the inner tank 22 by an adiabatic fixing device 24. The heat insulating fixture 24 includes a heat insulating sleeve 241, a sleeve positioning member 242, and a support member 243.
The insulating sleeve 241 may be made of an insulating material, for example, the insulating sleeve 241 may be made of an insulating epoxy steel tube material, i.e., the insulating sleeve 241 may be an epoxy glass steel tube. The heat insulation sleeve 241 may be formed by splicing two semicircular heat insulation pipes, which are sleeved on the gas phase pipeline 23 and cover the gas phase pipeline 23.
The sleeve positioning part 242 is sleeved on the gas phase pipeline 23, and positions the heat insulation sleeve 241 at a preset position of the gas phase pipeline 23, wherein the preset position refers to a preset connection position of the gas phase pipeline 23 and the inner tank 22, and for example, the preset position can be an intermediate position of the gas phase pipeline 23 or a position of 1/3 length of the gas phase pipeline 23 from the gas phase interface 26. The sleeve positioning member 242 includes an outer sleeve 2421 and two washers 2422.
The outer jacket 2421 is sleeved on the gas phase pipe 23, which covers the heat insulating jacket 241, i.e., the outer jacket 2421 is sleeved outside the heat insulating jacket 241. The outer sleeve 2421 may be a stainless steel seamless steel tube.
The two gaskets 2422 are sleeved on the gas phase pipeline 23 and are respectively connected with the upper end face and the lower end face of the outer sleeve 2421, so that the two gaskets 2422 and the outer sleeve 2421 enclose a cavity, the heat insulation sleeve 241 is enclosed in the cavity, and the gas phase pipeline 23 penetrates through the cavity.
By arranging the two gaskets 2422 and the outer sleeve 2421 on the outer side of the heat insulation sleeve 241, the heat insulation sleeve 241 is limited in a cavity surrounded by the gaskets 2422 and the outer sleeve 2421, and the heat insulation sleeve 241 is effectively fixed on the preset position of the gas phase pipeline 23.
The washer 2422 may be formed by two semi-circular shims that are spliced together.
The diameter of the washer 2422 is larger than the diameter of the outer sleeve 2421 such that the washer 2422 can seal the opening of the outer sleeve 2421.
Two washers 2422 are respectively coupled to upper and lower end surfaces of the outer sleeve 2421 by welding. In order to prevent the welding deformation caused by thermal expansion and contraction from generating larger local stress on the gas-phase pipeline 23 and the gasket 2422, gap welding can be adopted for the welding, so that the welding deformation amount is controllable.
The support member 243 has one end connected to the inner vessel 22 and the other end connected to the outer sleeve 2421, and the support member 243 connects the inner vessel 22 and the outer sleeve 2421 by welding. The support member 243 may be a support plate.
The distance D between the inner vessel 22 and the outer wall of the gas phase conduit 23 is maintained in the range of 25-35mm by the supporting action of the supporting member 243.
In fig. 3, only one heat insulating fixing device 24 is shown, but not limited thereto, the gas phase pipe 23 may be fixed to the inner tank 22 by two or more heat insulating fixing devices 24, and a plurality of heat insulating fixing devices 24 may be disposed between the inner tank 22 and the gas phase pipe 23 at intervals.
According to the invention, the heat insulation sleeve is arranged at the joint of the gas phase pipeline and the tank body (the inner tank body), the sleeve positioning component is used for limiting the heat insulation sleeve, and the support component is used for connecting the sleeve positioning component and the tank body to fix the gas phase pipeline on the outer wall of the tank body, so that the heat exchange between the gas phase pipeline and the outer wall of the tank body is greatly reduced through the heat insulation effect of the heat insulation sleeve while the gas phase pipeline is effectively fixed on the outer wall of the tank body, the condition that the gas in the gas phase pipeline is liquefied is avoided, and the heat insulation performance of the tank body is also improved.
The foregoing is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all equivalent structural changes made by applying the descriptions and the drawings of the present invention are included in the scope of the present invention.
