The utility model discloses a vacuum insulation pipe which comprises an outer pipeline and an inner pipeline, and a vacuum layer is arranged between the outer pipeline and the inner pipeline. The end portion of the outer pipeline and the end portion of the inner pipeline are sealed through a corrugated connecting ring which comprises an outer straight pipe and an inner corrugated pipe with a stretching function, one end of the outer straight pipe is connected to the end portion of the outer pipeline, the other end of the outer straight pipe is connected with one end of the inner corrugated pipe, and the other end of the inner corrugated pipe is connected to the end portion of the inner pipeline. The vacuum insulation pipe is simple in structure and reasonable in design, the phenomena that the vacuum insulation pipe is deformed or weld joints crack can be effectively avoided when the vacuum insulation pipe expands with heat and contracts with cold due to temperature difference of the inner pipeline and the outer pipeline, and the vacuum insulation pipe has good popularization and application value.
Description
Technical field
The utility model relates to a kind of high temperature media adiabatic apparatus, refers to it is a kind of vacuum heat-insulating pipe of regulating the inside and outside function of expanding with heat and contract with cold of pipeline that has particularly.
Background technique
At present, vacuum heat-insulating pipe is widely applied in the industries such as solar light-heat power-generation, solar airconditioning, solar heating, oilfield chemical, heating installation conveying.Vacuum heat-insulating pipe and traditional antivacuum thermal insulating material such as heat preservation rock etc. are compared, and it is superior that the former has thermal insulation property, characteristics such as thermal loss is low, protection environment.But because mostly vacuum heat-insulating pipe is bilayer or multilayer shell structure, the temperature difference of inside and outside layer support is very big, the effect of expanding with heat and contract with cold because of the material in the vacuum heat-insulating pipe easily makes vacuum heat-insulating pipe that the risk that produces deformation or bond open be arranged, thereby destroys the function of the adiabatic heat-insulation of vacuum heat-insulating pipe.
The model utility content
The purpose of this utility model is exactly the deficiency that will solve the above-mentioned background technology, provide a kind of simple in structure, have and regulate the inside and outside vacuum heat-insulating pipe that expands with heat and contract with cold of pipeline.
The technical solution of the utility model is: a kind of vacuum heat-insulating pipe, it comprises outer layer pipe and inner layer pipe, it is vacuum layer between described outer layer pipe and the inner layer pipe, it is characterized in that: the end of described outer layer pipe and inner layer pipe is by the sealing of ripple fastener rings, described ripple fastener rings comprises outer straight-through tube and has the internal layer bellows of Telescopic, one end of outer straight-through tube is connected the outer layer pipe end, the other end of outer straight-through tube is connected with an end of internal layer bellows, and the other end of internal layer bellows is connected the end of inner layer pipe.
In such scheme:
Be provided with shielded conduit in the vacuum layer between described outer layer pipe and inner layer pipe, the end of shielded conduit and ripple fastener rings are tightly connected.
Be provided with getter in the described vacuum layer.
Described getter is arranged on the end face of shielded conduit.
The material of described ripple fastener rings is stainless steel.
Offer the vacuum brazing hole on the described outer layer pipe, can be used for extracting the air of the vacuum layer between outer layer pipe and the inner layer pipe.
The joint of described outer layer pipe is connected and fixed the device butt joint by pipeline, and described pipeline is connected and fixed device for connecting heat insulation ring.
The material of described connection heat insulation ring is fluoroplastic.
The utility model is simple in structure, and when the inner layer pipe of vacuum heat-insulated pipe and outer layer pipe produced the deformation of expanding with heat and contract with cold because of temperature difference, the ripple fastener rings can carry out flexible compensation synchronously to vacuum heat-insulating pipe.And the design of shielded conduit has certain radiation shielding effect to the heat that the internal layer pipeline vacuum conducts, and more can ensure the thermal insulation property of vacuum heat-insulating pipe.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, is convenient to be well understood to the utility model, but they do not constitute restriction to the utility model.
A kind of vacuum heat-insulating pipe as shown in Figure 1, it comprises outer layer pipe 1 and inner layer pipe 2, be vacuum layer 4 between outer layer pipe 1 and the inner layer pipe 2, offer vacuum brazing hole 7 at outer layer pipe, vacuum brazing hole 7 can be used for extracting the air of the vacuum layer 4 between outer layer pipe 1 and the inner layer pipe 2.Joint at outer layer pipe 1 is connected and fixed device 8 butt joints by pipeline, pipeline is connected and fixed the connection heat insulation ring of device 8 for making by fluoroplastic, when the vacuum heat-insulated pipe need dock, joint at outer layer pipe 1 can be directly fastening by connecting heat insulation ring, prevents vacuum layer 4 and ambient air heat loss through convection in the pipeline.
Innovative point of the present utility model is: the end at outer layer pipe 1 and inner layer pipe 2 seals by ripple fastener rings 3, ripple fastener rings 3 is for to make by stainless steel material, ripple fastener rings 3 comprises outer straight-through tube 3.1 and has the internal layer bellows 3.2 of Telescopic, one end of outer straight-through tube 3.1 is connected outer layer pipe 1 end, the other end of outer straight-through tube 3.1 is connected with an end of internal layer bellows 3.2, and the other end of internal layer bellows 3.2 is connected the end of inner layer pipe 2.Because ripple fastener rings 3 has Telescopic; when the inner layer pipe 2 of vacuum heat-insulated pipe and outer layer pipe 1 produce the deformation of expanding with heat and contract with cold because of temperature difference; ripple fastener rings 3 can carry out flexible compensation synchronously to vacuum heat-insulating pipe; prevent that vacuum heat-insulating pipe from producing deformation or bond open, the function of the adiabatic heat-insulation of protection vacuum heat-insulating pipe.
Be provided with shielded conduit 6 in the vacuum layer 4 between outer layer pipe 1 and inner layer pipe 2, the bottom end face of the internal layer bellows 3.2 in the end of shielded conduit 6 and the ripple fastener rings 3 is tightly connected, the design of shielded conduit 6 can have certain radiation shielding effect to the heat of inner layer pipe 2 vacuum conduction, more can ensure the thermal insulation property of vacuum heat-insulating pipe.
4 are provided with getter 5 in vacuum layer, and getter 5 specifically is arranged on the end face of shielded conduit 6.
The utility model is simple in structure, and is reasonable in design, and the phenomenon that causes vacuum heat-insulating pipe to produce deformation or bond open in the time of can effectively avoiding vacuum heat-insulating pipe to produce the deformation of expanding with heat and contract with cold because of the inside and outside layer of pipeline temperature difference takes place, and has the excellent popularization using value.
