Abstract
The invention provides an ultralow-temperature and ultra-vacuum aluminum-magnesium alloy sealing ring. The aluminum-magnesium alloy sealing ring comprises a sealing ring body made of an aluminum-magnesium alloy, wherein the sealing ring body is circular; the section of the sealing ring body is a regular hexagon which comprises six edges; sealing and cutting edges are arranged on the sealing ring; the sealing and cutting edges are linear cutting edges; the number of the sealing and cutting edges is two; the two sealing and cutting edges are arranged at opposite angles of two ends of the sealing ring body; the two sealing and cutting edges are distributed in an axial symmetry manner by taking the section of the sealing ring body as a reference surface. The ultralow-temperature and ultra-vacuum aluminum-magnesium alloy sealing ring is free of damage to a device interface flange, convenient to mount and high in cost performance; the sealing ring is widely used for connecting and sealing vacuum parts under low-temperature, ultralow-temperature and normal-temperature conditions; the application range is widened; the product using effect is improved.
Description
Technical field
The present invention relates to a kind of ultralow temperature, ultravacuum aluminum-magnesium alloy seal ring, under ultralow temperature, ultravacuum working environment, the connection between vacuum component and sealing.
Background technique
Vacuum system consists of different Connecting format various elements such as vacuum equipment, flange, pipelines, is also by multiple parts, and the assembly of multiple different materials is set up.The different encapsulating method of these parts miscellaneous links together, these encapsulating methods should ensure that the reliable connection of part prevents from being leaked gas by interface again, in order to ensure the airtight quality of vacuum system, the leak rate of vacuum system is controlled within the specific limits, so vaccum seal ring is the major issue in Vacuum System Design, assembly process.And the material of general seal ring is rubber, plastics and metal o-ring, the material of conventional metal o-ring has spun gold and oxygen free copper two kinds, because the restriction of material characteristic, Environmental Conditions has narrow limitation, generally be used in normal temperature environment, cannot use in ultralow temperature, ultravacuum environment.
Summary of the invention
For the problems referred to above, the invention provides a kind of ultralow temperature, ultravacuum aluminum-magnesium alloy seal ring.
For solving above technical problem, technological scheme provided by the invention is:
A kind of ultralow temperature, ultravacuum aluminum-magnesium alloy seal ring, it is characterized in that, comprise the seal ring main body be made up of aluminum-magnesium alloy, described seal ring body shape is circular, seal ring main body section is regular hexagon, comprise 6 seamed edges, described seal ring is provided with the sealing edge of a knife, the described sealing edge of a knife is the line style edge of a knife, described sealing edge of a knife quantity is two, described two sealing edges of a knife are positioned on diagonal angle, described seal ring main body two ends, and with seal ring main body section for reference level, two sealing edges of a knife distribute axisymmetricly;
A kind of ultralow temperature, ultravacuum aluminum-magnesium alloy seal ring, is characterized in that, the annealed process of described seal ring main body;
Beneficial effect of the present invention is:
1, structure is simple, easy making process, the aluminum-magnesium alloy because of material selection annealed process, make seal ring be provided with anticorrosive, the feature that radiation hardness matter heavily fortified point amount is light, density is low, thermal diffusivity good, crushing resistance is strong, ductility is high and toughness is high, simultaneously in conjunction with the patina of aluminum-magnesium alloy Surface Creation, there is extremely strong corrosion resistance, substantially increase the usability of seal ring, extend the working life of seal ring, there is the sealed characteristic of linear sealing simultaneously, enhance the sealability of seal ring.
2, the present invention does not damage equipment interface flange, convenient installation, and cost performance is good, is widely used in the connection between the vacuum component under low temperature, ultralow temperature and normal temperature condition and sealing, expands using scope, strengthens product using effect.
3, uniqueness is provided with the sealing edge of a knife, sealing knife-edge design symmetrical on seal ring, once the sealing edge of a knife has problem, only seal ring need be changed, avoid the damage of equipment interface flange, almost do not affect equipment interface flange, extension device flange maintained easily while working life.

Embodiment
A kind of ultralow temperature as described in Figure 1, ultravacuum aluminum-magnesium alloy seal ring, it is characterized in that, comprise the seal ring main body 1 be made up of aluminum-magnesium alloy, described seal ring main body 1 shape is circular, seal ring main body 1 cross section is regular hexagon, comprise 6 seamed edges, described seal ring 1 is provided with the sealing edge of a knife 2, the described sealing edge of a knife 2 is the line style edge of a knife, the described sealing edge of a knife 2 quantity is two, described two sealing edges of a knife 2 are positioned on diagonal angle, described seal ring main body 1 two ends, and with seal ring main body 1 cross section for reference level, two sealing edges of a knife 2 distribute axisymmetricly; The annealed process of described seal ring main body 1;
Beneficial effect of the present invention is:
1, structure is simple, easy making process, the aluminum-magnesium alloy because of material selection annealed process, make seal ring be provided with anticorrosive, the feature that radiation hardness matter heavily fortified point amount is light, density is low, thermal diffusivity good, crushing resistance is strong, ductility is high and toughness is high, simultaneously in conjunction with the patina of aluminum-magnesium alloy Surface Creation, there is extremely strong corrosion resistance, substantially increase the usability of seal ring, extend the working life of seal ring, there is the sealed characteristic of linear sealing simultaneously, enhance the sealability of seal ring.
2, the present invention does not damage equipment interface flange, convenient installation, and cost performance is good, is widely used in the connection between the vacuum component under low temperature, ultralow temperature and normal temperature condition and sealing, expands using scope, strengthens product using effect.
3, uniqueness is provided with the sealing edge of a knife, sealing knife-edge design symmetrical on seal ring, once the sealing edge of a knife has problem, only seal ring need be changed, avoid the damage of equipment interface flange, almost do not affect equipment interface flange, extension device flange maintained easily while working life.
The above; be only the present invention's preferably embodiment, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
