Abstract
The invention discloses a vacuum tube with an inner insulating layer and a schematic diagram of the vacuum tube. An insulating coating layer is coated on the outer wall of an inner tube of the vacuum tube, an insulating layer is arranged between the inner tube and an outer tube, and energy on the inner tube can be prevented from directly irradiating to the inner wall of the outer tube and can be absorbed and discharged to the atmosphere by the outer tube. The vacuum tube has the advantages of good pressure resistance, high corrosion resistance, stable vacuum degree, less proneness to damage and the like, and is better in heat and coldness insulation as compared with common vacuum tubes, and energy loss in steam, cold air and hot water delivery is reduced. Besides, the vacuum tube is simple in structure.
Description
Technical field
The present invention relates to a kind of pipeline, particularly relate to a kind of vacuum pipe with thermal-protective coating.
Background technique
At present, the purposes of pipeline is very extensive, and particularly in all conglomeraties such as chemical industry, light industry, medical treatment, carrying steam and cold air with pipeline is very general thing.But no matter pipeline when steam, cold air or hot water, is to take with asbestos, gypsum wrapping pipeline in transmission, and it is heat insulation or every cold performance extreme difference all, all can the loss lot of energy when particularly transmitting at a distance, thus reduce productivity effect.Therefore, people adopt ordinary vacuum tube to transmit cold and hot gas, though its effect is better than asbestos, gypsum wrapping pipeline, its degree of vacuum of ordinary vacuum tube is not high, the metal partion (metp) emission energy at vacuum tube two ends is many, so still there is the energy of quite a few to be lost in diabatic process.
Up to the present, have the vacuum pipe of making of inner insulating layer, there is no both at home and abroad, patent documentation is not seen record yet.
Summary of the invention
Purpose of the present invention is intended to provide a kind of vacuum tube with inner insulating layer, the outer wall of inner tube of its vacuum tube scribbles one deck thermal insulation coatings, between interior pipe and the outer tube one deck thermal-protective coating is arranged, the energy direct irradiation in preventing on the pipe is on the inwall of outer tube, and energy is absorbed by outer tube and is emitted in the atmosphere.It is good that it has an anti-pressure ability, the Corrosion Protection height, and the vacustat of vacuum tube, characteristics such as not fragile compare with ordinary vacuum tube that it is heat insulation, better every cold property, reduce the energy loss of pipeline in transmitting steam, cold air and hot water process, and simple in structure.
For achieving the above object, the technological scheme that the present invention takes is: interior tube-surface scribbles one deck thermal insulation coatings, and outer tube of its outside cover is with one deck again between outer tube and the interior pipe and has high-low temperature resistant, can prevent temperature radiation, heat-shielding performance is the thermal-protective coating made of good material again.Between outer tube and the thermal-protective coating, between thermal-protective coating and the interior pipe certain vacuum gap is arranged, there is dividing plate at the two ends of interior pipe and outer tube and thermal-protective coating, and the effect of two endplates is the thermal-protective coatings that support and seal between the inner and outer pipes.Flange plate is equipped with at the two ends of interior pipe, and the connection between vacuum tube and the vacuum tube is to connect by the screw on the flange plate.A vacuumizing and exhausting tubule is arranged on the dividing plate of one end, and there is a sealing screw top of vacuumizing and exhausting tubule, and the air between interior pipe and the thermal-protective coating, between outer tube and the thermal-protective coating ejects in the vacuumizing and exhausting tubule.In between pipe and the thermal-protective coating, be pumped into vacuum between outer tube and the thermal-protective coating after, twist under the sealing screw, sealing vacuumizing and exhausting tubule makes to keep vacuum in the pipe.

Specific embodiments
Below in conjunction with accompanying drawing the embodiment of the invention is described further.
A kind of vacuum tube with inner insulating layer provided by the invention has vacuum structure, its vacuum structure: interior pipe (1) surface scribbles one deck thermal insulation coatings (8), interior pipe (1) outside is with an outer tube (3), is with a thermal-protective coating (2) again between outer tube (3) and the interior pipe (1).Between outer tube (3) and the thermal-protective coating (2), between thermal-protective coating (2) and the interior pipe (1) vacuum layer (9) is arranged, there is dividing plate (4) at the two ends of interior pipe (1) and outer tube (3) and thermal-protective coating (2), and the effect of two endplates (4) is the thermal-protective coating (2) between support and sealed inner tube (1) outer tube (3).Flange plate (5) is equipped with at the two ends of interior pipe (1), and the connection between vacuum tube and the vacuum tube is to connect by the screw on the flange plate (5).A vacuumizing and exhausting tubule (6) is arranged on the dividing plate of one end (4), there is a sealing screw (7) vacuumizing and exhausting tubule (6) top, and the air between interior pipe (1) and the thermal-protective coating (2), between outer tube (3) and the thermal-protective coating (2) ejects from vacuumizing and exhausting tubule (6) lining.In between pipe (1) and the thermal-protective coating (2), be pumped into vacuum between outer tube (3) and the thermal-protective coating (2) after, sealing screw (7) is twisted down, sealing vacuumizing and exhausting tubule (6) makes the interior maintenance of pipe vacuum.
Claims (1)
1. vacuum tube with inner insulating layer, it is characterized in that: interior pipe (1) surface scribbles one deck thermal insulation coatings (8), interior pipe (1) outside is with an outer tube (3), overlap thermal-protective coating (2) again between outer tube (3) and the interior pipe (1), between outer tube (3) and heat insulation (2) layer, between thermal-protective coating (2) and the interior pipe (1) vacuum layer (9) is arranged, there is dividing plate (4) at the two ends of interior pipe (1) and outer tube (3) and thermal-protective coating (2), flange plate (5) is equipped with at the two ends of interior pipe (1), a vacuumizing and exhausting tubule (6) is arranged on the dividing plate of one end (4), and there is a sealing screw (7) vacuumizing and exhausting tubule (6) top.
