Technical Field
The invention relates to an elbow, in particular to an integrally formed heat-preservation elbow capable of preserving heat.
Background
The heat-insulating operation is a conventional operation in industrial production, and when the direction of a pipeline is changed, a heat-insulating elbow is required. At present, the heat-insulating elbows used in domestic industrial production are basically formed by directly welding in site construction, so that the construction work is long, the sealing performance is poor, the phenomena of slotting and disjointing are easy to occur, the service life is seriously shortened, the heat-insulating effect is influenced, and the production cost is increased.
The existing production needs a heat-insulating elbow which is not easy to crack and disjointed and has better performance. So as to ensure long-term and high-efficiency operation of production.
Disclosure of Invention
In order to solve the technical problems, the invention provides the heat-insulating elbow which adopts an integrated pressing and forming technology, has no welding line, solves the problems that the heat-insulating elbow is easy to crack and disjointed in the prior art, and has convenient installation and good heat-insulating effect.
The technical scheme provided by the invention is as follows:
the utility model provides a heat preservation elbow, includes two parts of mirror symmetry's close coupling, every part is outer pillar layer, heat preservation and return bend layer from outside to inside in proper order, outer pillar layer and return bend lamination make integral type cavity structure, and the heat preservation is filled in the cavity.
Furthermore, the outer protective pipe layer is made of metal or polyethylene.
Furthermore, the bent pipe layer is made of metal or polyethylene.
Furthermore, the insulating layer is made of polyurethane foam.
Further, the elbow layer comprises an elbow section and a straight pipe section extending from the elbow section. The straight pipe section can be directly connected with the heat preservation straight pipe.
Furthermore, the connection mode of the left part and the right part is one of welding, riveting or clamping.
The heat-insulating elbow is formed by adopting the two parts in an integrated structure, has attractive appearance, can directly connect the two parts in a sealing way by adopting welding, riveting, clamping and the like during construction, is very convenient to construct, has no welding line, keeps the rigidity of the original material, has good heat-insulating effect and sealing property, bears large pressure, and does not have the phenomena of cracks, disjointing and the like. And guarantee is provided for smooth production.
