Abstract
Provided is a vacuum low temperature pipeline connector with two opposing principles in nature. The connector with two opposing principles in nature comprises a yin connector and a yang connector. A PTFE gasket is arranged between the yin connector and the yang connector. An opposite direction of the combination of the yin connector and the yang connector which corresponds to the yin connector and the yang connector are connected with a yin connector drivepipe and a yang connector drivepipe. The yin connector drivepipe and the yang connector drivepipe are inserted into two pipelines to be connected respectively.
Description
Technical field
The utility model relates to a kind of vacuum and low temperature pipeline male and female connector, divides a kind of vacuum and low temperature pipeline male and female connector in chemical industry field in particular for sky.
Background technique
Develop rapidly with the speed more than 10% every year as main large-scale industrial gas market take liquefied gas at low temp such as liquid oxygen, liquid nitrogen, liquid argon and LNG Liquefied natural gas.The conveying of these cryogenic liquides in using the zone then mainly undertaken by vacuum low-temperature heat insulation tube, be subjected to place or other facilities of periphery, and the impact that can cause when avoiding the cryogenic piping straight line in axial direction temperature difference displacement of pipeline and stress to increase, behind the every several meters straight section stringings of cryogenic piping, just need to change the pipeline trend, and vacuum low-temperature heat insulation tube is considered transportation when making, then be divided into some sections shippings to on-the-spot, after reaching the spot, these pipelines need to be assembled, how effectively to connect between the adjacent channel, how can satisfy Simple fast installs, can satisfy again at low temperatures the flexible requirement to structure, and keep good seal in the situation frequently in difference variation, not produce larger leaking heat at the jointing place after can also guaranteeing to connect.
Be main to the connection between the cryogenic piping adjacent channel mainly with flange connection type at present; Because at flange connections, the effective heat bridge between flange and the inner tube is shorter, conducts heat very large, if do not adopt the external insulation layer, the heat in the atmosphere environment is delivered in the vacuum tube, causes the increase of evaporation loss.So the existing pipeline that adopts flange to connect, needing externally increases thermal insulation layer after the flange connection; When pipeline overhauls or changes, need to remove thermal insulation layer, after maintenance and replacing are finished, also need again to increase again thermal insulation layer; For at the scene construction, itself construct inconvenient, and increased a lot of workloads.
Summary of the invention
For the defects that exists in the prior art, the utility model provides a kind of vacuum and low temperature pipeline male and female connector, described male and female connector comprises negative joint and male connector, has the PTFE pad between described negative joint and the male connector, opposite direction in described male and female connector combination is connected with negative joint sleeve pipe and male connector sleeve pipe corresponding to negative joint with corresponding to male connector, and wherein said negative joint sleeve pipe and described male connector sleeve pipe are inserted into respectively in the 2-section pipe road to be connected.
Preferably, have locating slot at described male connector, have screens projection corresponding to described locating slot at described negative joint, the location of realizing male and female connector by described locating slot and described screens projection.
Preferably, on described negative joint and male connector, also have for the groove of fixing respectively described negative joint sleeve pipe and described male connector sleeve pipe.
Preferably, at least one in described negative joint, male connector, negative joint sleeve pipe and the male connector sleeve pipe adopts thickness to make less than the stainless steel material of 2mm.
The vacuum tube inner tube is cryogenic liquide, outer tube is normal temperature, temperature gradient is very large, process bad meeting and produce very large temperature difference stress, the male and female connector sleeve pipe has adopted the stainless steel material less than 2mm, satisfying the heat transmission that has greatly reduced male and female connector under the requirement of strength, the male and female connector both sides increase the adapter that certain-length is arranged according to calculating each, also can reduce the heat transmission of male and female connector, the seal style of male and female connector adopts plane sealing, middle lining PTFE pad, consider that the length of pipeline to the requirement of the concentricity of male and female connector, has adopted the locating slot structure at male connector, component are in the process of expanding with heat and contract with cold that temperature variation causes, all the time so that male and female connector is in concentric position, guarantee the stability of sealing.

Embodiment
As shown in Figure 1, a kind of vacuum and low temperature pipeline male and female connector, described male and female connector comprises negative joint 4 and male connector 2, has PTFE pad 3 between described negative joint 4 and the male connector 2, opposite direction in described male and female connector combination is connected with negative joint sleeve pipe 5 and male connector sleeve pipe 1 corresponding to negative joint 4 with corresponding to male connector 2, and wherein said negative joint sleeve pipe 5 and described male connector sleeve pipe 1 are inserted into respectively in the 2-section pipe road to be connected.Have locating slot at described male connector 2, have screens projection corresponding to described locating slot at described negative joint 4, the location of realizing male and female connector by described locating slot and described screens projection.On described negative joint 4 and male connector 2, also have for the groove of fixing respectively described negative joint sleeve pipe 5 and described male connector sleeve pipe 1.In described negative joint 4, male connector 2, negative joint sleeve pipe 5 and the male connector sleeve pipe 1 at least one adopts thickness to make less than the stainless steel material of 2mm.
The Simple fast that male and female connector of the present utility model has satisfied between the on-the-spot adjacent cryogenic piping is installed, reach at low temperatures the flexible requirement to structure, can keep good seal in the situation frequently in difference variation, not produce larger leaking heat at the jointing place after connecting.
Above embodiment further specifies of the present invention, and those skilled in the art are that above-mentioned explanation is not limited to protection scope of the present invention with being to be understood that.
Claims (4)
