Abstract
This invention discloses a metal vacuum heat insulation sleeve including a metal inner tube characterizing in having a metal outer tube, end covers at both ends of the outer tube connected to the inner tube, a pumped connector on a cover, a vacuum cavity between the inner tube and the outer tube, a ripple section on the outer tube and a welded end tube at both ends of the inner tube.
Description
One, technical field:
The present invention relates to a kind of metal vacuum heat-insulation sleeve pipe that is used for heat supply or refrigeration pipe.
Two, background technique:
At present, in known technology, the heat insulating tube that is used for heat supply or refrigeration pipe, be to make thermal insulation layer at metal external application thermal-protective material, traditional thermal-protective material is as mineral wool, glass silk flosssilk wadding, rock wool, perlite etc., because shortcomings such as its moisture absorption is strong, thermal insulation property is poor, working life is short, yielding are not suitable for the thermal-protective coating with direct buried pipe; At present, extensively adopt the polyurethane thermal-protective material, there is the cost height in it, compressive strength is low, yielding and shortcomings such as non-refractory, construction cost height, can bring environmental pollution when pipeline is discarded, and wastes energy.
Three, summary of the invention:
The object of the present invention is to provide a kind of metal vacuum heat-insulation sleeve pipe, to overcome the deficiency of known technology.
The present invention is achieved in that a kind of metal vacuum heat-insulation sleeve pipe, it comprises a metal inner pipe (1), its special way is to have a metal outer pipe (2), has the end cap (3) that is connected with metal inner pipe (1) at the two ends of metal outer pipe (2), on an end cap (3), has vacuumizing joint (4), between metal inner pipe (1) and metal outer pipe (2), has vacuum chamber (5), on metal outer pipe (2), have one section bellows segment (6), have welding ends pipe (7) at the two ends of metal inner pipe (1).
Metal vacuum heat-insulation sleeve pipe provided by the invention, it is good to have heat-shielding performance, and manufacture cost, construction cost is low and the advantage of energy saving, and is fit to carry the medium of higher temperature and the medium of lower temperature, and its working life is longer.
Four, description of drawings:
Fig. 1: a kind of structure sectional view of the present invention.
Five, embodiment:
The invention will be further described in conjunction with embodiment with reference to accompanying drawing.
Embodiment 1, accompanying drawing has provided a kind of concrete structure of the present invention, consult Fig. 1, a kind of metal vacuum heat-insulation sleeve pipe, it has a metal inner pipe (1), has a metal outer pipe (2), has the end cap (3) that is connected with metal inner pipe (1) at the two ends of metal outer pipe (2), on an end cap (3), has vacuumizing joint (4), between metal inner pipe (1) and metal outer pipe (2), has vacuum chamber (5), on metal outer pipe (2), have one section bellows segment (6), have welding ends pipe (7) at the two ends of metal inner pipe (1).Can adopt the metal inner pipe and the metal outer pipe of unlike material and different-thickness according to the needs of engineering.Determine the length of degree of vacuum and vacuum chamber thickness and bellows segment according to the needs of engineering.By vacuumizing joint vacuum chamber is vacuumized, and the sealing vacuumizing joint.Can vacuumize in processing factory, also can vacuumize at the construction field (site).The welding ends pipe at metal inner pipe two ends be used between each pipe welding and with the welding of other pipe fitting, pipeline connect the back in the joint with conventional method or adopt structure of the present invention to carry out heat insulation processing.
