Background technique
As shown in Figure 1, be used to transmit the vacuum pipe of liquid nitrogen, liquid argon, liquid oxygen and LNG Liquefied natural gas cryogenic liquides such as (LNG), its structure comprises: be sleeved on together overcoat 1 and interior pipe 2, be provided with heat insulation vacuum chamber 3 between overcoat 1 and the interior pipe 2.When two vacuum pipe butt joints; need at the scene the interface 4 of managing 2 in two vacuum pipes to be welded; then; overcoat 1 with case 5 and two vacuum pipes welds together again; the interior pipe 2 that is exposed to the outside is covered, forms protection chamber 6, and should protect chamber 6 to be evacuated with vaccum-pumping equipment.Like this, because the butt joint of vacuum pipe need use welding equipment and vaccum-pumping equipment to carry out field operation, make the butt joint of pipeline become unusual complicated and loaded down with trivial details.
The model utility content
Technical problem to be solved in the utility model is: the docking structure that the very easy vacuum pipe of a kind of butt joint that makes vacuum pipe is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the docking structure of vacuum pipe, comprise: a pair of vacuum pipe, each vacuum pipe comprises overcoat and interior pipe, be provided with heat insulation vacuum chamber between overcoat and the interior pipe, the butt end of the interior pipe of a vacuum pipe is provided with socket, be provided with the socket vacuum chamber that communicates with heat insulation vacuum chamber in this vacuum pipe between socket and the overcoat, the butt end of the interior pipe of another vacuum pipe is provided with the plug that matches with described socket, be provided with the plug vacuum chamber that communicates with heat insulation vacuum chamber in this vacuum pipe between plug and the overcoat, be provided with seal ring between the top of plug and the bottom of socket; This is fixed with each other by being arranged on its outer a pair of flange that puts to vacuum pipe.
The concrete structure of above-mentioned socket comprises: the fitting seat in being arranged on the butt end of pipe, and fitting seat is provided with annular chuck, and the uncovered of the socket vacuum chamber between annular chuck and the overcoat sealed by the end cap that is arranged on annular chuck and overcoat end; The concrete structure of above-mentioned plug comprises: the fitting seat in being arranged on the butt end of pipe, and fitting seat is provided with annular chuck, and the uncovered of the plug vacuum chamber between annular chuck and the overcoat sealed by the end cap that is arranged on annular chuck and overcoat end.
Between above-mentioned a pair of end cap, be provided with packing ring.
The beneficial effects of the utility model are: a pair of vacuum pipe described in the utility model separately is provided with a flange by managing plug and socket to be set respectively on the butt end and to put within it outside it, can dock easily and be fixed together, thereby avoided welding at the scene and vacuumizing, made the butt joint of vacuum pipe become very easily simple.
