The chuck solar water container that the vertical wall-hung band expands and protects
Technical field
The utility model relates to a kind of solar energy-saving cistern, especially relates to the chuck solar water container that a kind of vertical wall-hung band expands and protects.
Background technology
Along with popularizing of solar water heater, the user is more and more higher to the functional requirement of water heater.The solar water container of prior art, its structure generally comprises shell, water inlet pipe and water outlet pipe, heat exchanger and inner bag, and the shell inboard is provided with heat-insulation layer.This water tank also can carry out medium circulation by the heat exchanger in the water tank except adopting electrical heating, thereby improves the heat exchange effect of water tank.But present heat exchanger has brought potential safety hazard for the use of solar water container because structural reason when circulatory mediator runs into the problem of expanding with heat and contract with cold, certainly exists the bulbs of pressure of circulatory mediator heat exchanging device inwall.
Summary of the invention
The technical problems to be solved in the utility model provides the chuck solar water container that a kind of vertical wall-hung band that can alleviate the circulatory mediator bulbs of pressure expands and protects.
Technical problem to be solved in the utility model is achieved by the following technical solution: it comprises shell, water inlet pipe and water outlet pipe, medium circulation mouth and cabinet body, the shell inboard is provided with heat-insulation layer, be provided with the inner bag chuck of annular between described heat-insulation layer and the cabinet body, upper space in cabinet body is provided with end socket outside the inner bag chuck, and the outer end socket of inner bag chuck is connected with the inner bag chuck of annular.
Inner bag chuck described in the utility model is provided with medium liquid feeding mouth and medium overfall.
Cabinet body described in the utility model all is provided with enamel coating on all and water engaging surface.
The said structure that the utility model adopts, because the upper space in cabinet body is provided with end socket outside the inner bag chuck that is connected with the inner bag chuck, guaranteed the thermal expansion space of circulatory mediator, the bulbs of pressure of circulatory mediator can be alleviated, solar water container potential safety hazard in use can be eliminated wall of inner container.

The specific embodiment
By Fig. 1, Fig. 2, Fig. 3 as can be known; the chuck solar water container of this vertical wall-hung band expansion protection comprises shell 1, water inlet pipe and water outlet pipe 2,3, medium circulation mouth 4 and cabinet body 5; shell 1 inboard is provided with heat-insulation layer 6; be provided with the inner bag chuck 7 of annular between described heat-insulation layer 6 and the cabinet body 5; upper space in cabinet body 5 is provided with end socket 8 outside the inner bag chuck, and the outer end socket 8 of inner bag chuck is connected with the inner bag chuck 7 of annular.Inner bag chuck 7 can be welded on the cabinet body 5, and the outer end socket 8 of inner bag chuck is welded into one with inner bag chuck 7.When the circulatory mediator temperature uprises thermal expansion, outside the upper space inner bag chuck of cabinet body 5, reserved enough expansion spaces in the end socket 8, can alleviate the bulbs of pressure of the interior medium of inner bag chuck to wall of inner container.Described inner bag chuck 7 is provided with medium liquid feeding mouth 9 and medium overfall 10, adds circulatory mediator (oil, water, alcohol, anti-icing fluid etc.) from medium liquid feeding mouth 9, and unnecessary medium can flow out from medium overfall 10.Medium liquid feeding mouth and the height and position of medium overfall on the inner bag chuck have passed through accurate calculating, have reached best heat exchange function and bulbs of pressure protection height.Described cabinet body 5 all is provided with enamel coating on all and water engaging surface.Carry out enamel coating and handle, can promote the working life of cabinet body.
