Abstract
The utility model discloses a vacuum heat insulation sleeve's structure, in the periphery of the thermal-insulated connecting pipe that needs to keep warm, embolia the heat insulation sleeve who suits with connecting pipe length and appearance, at the both ends of connecting pipe, install respectively and take the internal screw thread sleeve pipe retainer plate, constitute real empty room. If the extension or branch extension connecting pipe is needed, a plurality of branch connectors with inner through holes and outer threads can be screwed and fixed with the inner threads of the fixing ring, and the threads of the other branches of the connectors are connected with another group of vacuum heat-insulating sleeves according to the method, so that the device forms a whole set of vacuum heat-insulating layer. Adopt the utility model discloses, not only make cold, the thermal-insulated ideal effect that reaches of heat retaining of hot liquid, can protect the connecting pipe for a long time moreover to replace there is the pollution to the environment, easy ageing, cracked foamed plastic are favorable to the environmental protection.
Description
The utility model relates to hot and cold pipe insulation device, particularly a kind of vacuum heat-insulation sleeve pipe.
From the heat supply waterpipe of large common facility, the cold and hot water drinking machine that cold water pipes is used always to family, in the course of conveying of hot and cold liquid, all must solve hot and cold pipe and the problem of carrying target connecting tube heat-insulation and heat-preservation.At present, solve heat insulation method and generally adopt foamed plastics, form thermal-protective coating in hot and cold pipeline and the peripheral coating of connecting tube.The shortcoming of above-mentioned thermal-protective coating is that foamed plastics not only wears out easily, breaks, life time is short, and foamed plastics has certain toxicity, processing, regeneration difficulty, is unfavorable for environmental protection.
The purpose of this utility model is the shortcoming at above-mentioned foam thermal insulation layer; develop a kind of vacuum heat-insulation sleeve pipe; in the periphery of hot and cold liquid delivery tube with the connecting tube of carrying target; increase vacuum layer; good effect of heat insulation not only; and be adapted to the connecting tube of different shape, and connecting tube there is the effect of reinforcement protection.
The purpose of this utility model is achieved in that
In the periphery of the connecting tube that needs insulation, be inserted in the thermal sleeve that adapts with connecting tube length and profile.The interval that keeps 1 to 30 millimeter between thermal sleeve and the connecting tube.At the two ends of connecting tube, tapped sleeve pipe retainer ring is installed respectively.By the cylindrical of connecting tube, the interior circle of sleeve pipe and the inboard vacuum chamber of forming of retainer ring at two ends.Before above-mentioned installation finishes, adopt proper technology to seal and vacuumize, make internal vacuum chamber form vacuum.Continue if desired to prolong or branch's prolongation connecting tube, can adopt to have in 1 to 5 branch has threaded joint outside the intercommunicating porosity, and an internal thread with retainer ring wherein spins fixing and sealing.Again the screw thread of 2 to 4 other branches of joint is connected with other one group of vacuum heat-insulation sleeve pipe of being made up of connecting tube, sleeve pipe, retainer ring by above-mentioned method, till the end objectives of hot and cold conveyance conduit, said apparatus forms a whole set of vacuum heat-insulating layer.
Owing to adopt the utility model, not only make the heat insulation ideal effect that reaches of guarantor's heat of hot and cold liquid, and can protect connecting tube for a long time, and get for environment is had pollution, aging, cracked easily foamed plastics helps environmental protection.
In conjunction with the accompanying drawings and embodiments, further describe structure of the present utility model.
Fig. 1 is the schematic representation of the utility model embodiment's vertical section structure.
Fig. 2 is the schematic representation of the joint main-vision surface structure among the utility model embodiment.
Embodiment:
In the periphery of the connecting tube 1 that needs insulation, be inserted in the thermal sleeve 2 that adapts with connecting tube 1 length and profile.The interval that keeps 20 millimeters between thermal sleeve 2 and the connecting tube 1.At the two ends of connecting tube 1, the sleeve pipe retainer ring 4 of difference mounting strap internal thread 3.By the inboard of the retainer ring 4 at the interior circle of the cylindrical of connecting tube 1, sleeve pipe 2 and two ends, form vacuum chamber 5.Before above-mentioned installation finishes, adopt binder to seal the position that each parts connects, and vacuumize, make vacuum chamber 5 form vacuum.Continue to prolong if desired or branch prolongs connecting tube 1, can adopt to have has the outer joint 7 that screw thread 6 arranged of intercommunicating porosity 8 and the internal thread 3 of retainer ring 4 to spin fixing in two branches.Again the screw thread 6 of another branch of joint 7 is connected with other one group of vacuum heat-insulation sleeve pipe of being made up of connecting tube 1, sleeve pipe 2, retainer ring 4 by above-mentioned method, till the end objectives of hot and cold conveyance conduit, said apparatus forms a whole set of vacuum heat-insulating layer.
