The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of closing device for solar energy heat collection pipe, comprise thermal-collecting tube and the capping for encapsulating thermal-collecting tube openend, described thermal-collecting tube comprises outer tube and interior pipe, described outer tube and interior pipe seal at opening part, the outer surface of described thermal-collecting tube openend is provided with external screw thread, described capping is provided with water inlet pipe and outlet pipe, inlet opening and apopore is respectively equipped with in capping below corresponding described water inlet pipe and outlet pipe, described capping comprises enclosing cover and Nei Sai, the inner side of described enclosing cover is provided with the internal thread matched with described external screw thread, the diameter compatible of described interior plug and thermal-collecting tube openend closes.Capping adopts insulation material, requires high temperature resistantly to reach more than 300 degree, the temperature of more than 200 degree during to adapt to thermal-collecting tube air drying, and has certain plasticity, and mechanical strength is high.
Further, the outside of described enclosing cover is also provided with the metal protection layer matched with enclosing cover.The capping of insulation material can prevent heat losses; but there is distortion possibility by external force at high operating temperatures, metal protection layer is set capping is further protected, the service life of capping can be extended; avoid capping to affect by external force and occur distortion, ensure the sealing effectiveness of capping.
Further, described external screw thread is arranged on described outer tube and interior pipe and sinters on the seal that formed.Described outer tube and interior pipe sinter at opening part and form seal, and the external diameter of described seal is less than or equal to the external diameter of thermal-collecting tube outer tube, and external screw thread is arranged on seal, and the size of corresponding capping is little, and materials are few, and cost is low, and monnolithic case is attractive in appearance.
Further, described external screw thread is arranged on the outer surface of described outer tube.Outer tube and interior pipe directly seal at opening part, external screw thread can be set directly at the surface of outer tube, because vacuum design between outer tube and interior pipe can be effectively heat insulation, the capping be threaded connection is little by the heat effects of thermal-collecting tube inside, capping can not because of high temperature deformation, and the metal protection layer outside enclosing cover can be selected not use at this.
Further, between described enclosing cover with interior plug, be also provided with the falope ring matched with the openend of described thermal-collecting tube.The sealing effectiveness that further guarantee capping is good.
Further, described metal protection layer is aluminum alloy material.Under the indeformable prerequisite of protection enclosure cover, ensure the lightweight of capping, facilitate installation and maintenance.
Further, described capping adopts special engineering plastics.Described special engineering plastics can be polyphenylene sulfide (PPS) or polyimides (PI).There is excellent heat endurance, wearability, creep resistance, good mechanical property.
The beneficial effects of the utility model are: the surface of heavy caliber vacuum heat collection pipe openend is provided with screw thread, capping is sealed by the openend of screw thread to thermal-collecting tube, not only structure is simple, long term seal is effective, easy to operate, cost is low, and explosion phenomenon can not be there is because thermal-collecting tube is impaired, ensure to install, the security safeguarded and use, in addition, the interior plug of capping and the diameter compatible of thermal-collecting tube close, avoid current direction thermal-collecting tube openend i.e. interior pipe and outer seal of tube place, water in thermal-collecting tube and capping are isolated, reduce the loss of heat, high insulating effect, capping adopts special engineering plastics high insulating effect, avoid the phenomenon of existing employing metalwork heat losses, this external capping also arranges metal protection layer, because metal protection layer is arranged on the skin of enclosing cover, not only prevent capping at high operating temperatures by external force deformation, the sealing effectiveness of further guarantee capping, in addition metal protection layer can not touch water in thermal-collecting tube, avoid the loss of thermal-collecting tube heat, ensure the heat insulation effect of thermal-collecting tube.
