Abstract
The utility model discloses a vacuum tube with an internal thermal insulating layer. A layer of thermal insulating coating is coated at the outer wall of an inner tube of the vacuum tube; a thermal insulating layer is arranged between the inner tube and an outer tube to prevent energy on the inner tube from directly irradiating on the inner wall of the outer tube; and the energy is absorbed by the outer tube to be discharged in the atmosphere. The vacuum tube with the internal thermal insulating layer, disclosed by the utility model, has the advantages of good pressure resisting capability, high anti-corrosion performance, steady vacuum degree of the vacuum tube, damage difficulty and the like. Compared with a normal vacuum tube, the vacuum tube with the internal thermal insulating layer has better thermal insulating and cold insulating performances, reduces energy loss during a process of conveying steam, cold air and hot water by pipelines and has a simple structure.
Description
Technical field
The utility model relates to a kind of pipeline, particularly relates to a kind of vacuum pipe with thermal-protective coating.
Background technique
At present, the purposes of pipeline is very extensive, in many industries such as chemical industry, light industry, medical treatment, is very general thing with line transportation steam and cold air particularly.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 at a distance from cold performance extreme difference all, all can the loss lot of energy when particularly transmitting at a distance, thus the reduction 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 in diabatic process, still there is the energy of quite a few to be lost.
Up to the present, have the vacuum pipe of processing of inner insulating layer, all do not see both at home and abroad, patent documentation is not seen record yet.
Summary of the invention
The purpose of the utility model 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; 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, and Corrosion Protection is high, the vacustat of vacuum tube, and characteristics such as not fragile compare with ordinary vacuum tube that it is heat insulation, better at a distance from 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 utility model is taked 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, the thermal-protective coating that the material that heat-shielding performance is good is again made.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 to support and seal the thermal-protective coating 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 lean on the screw on the flange plate to connect.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, sealing screw is twisted down, sealing vacuumizing and exhausting tubule makes to keep vacuum in the pipe.
