Description

Split type two two circulating solar energy water-heater water tanks of pressing

Technical field

The utility model relates to a kind of split type two two circulating solar energy water-heater water tanks of pressing.Especially mainly by water tank main body, exhaustion spill pipe, heat medium filling jar, communicating pipe combines.

Background technology

The separated type solar water heater is the new product that had just entered resident family in recent years.The separated type solar water heater mostly is pressure-bearing type.Heat-conducting medium and hot water are isolated by heat exchanger, have formed the heat-conducting medium circulatory system and hot-water heating system.Hot-water heating system is that pressure-bearing type has in use shown plurality of advantages: because pressure is arranged, feel satisfied in bathing 1.; 2. have pressure to exist, it is fast to go out water speed during with hot water; 3. can directly be connected with the running water water inlet, hot water is top ability of swimming water outlet, has replenished cold water in water outlet automatically.But, present separated type solar water heater, the heat-conducting medium circulatory system also is a pressure-bearing, this has just brought many drawbacks; 1. owing to there is pressure, therefore to structure, the material requirements height of system.In thermal-collecting tube, designed with copper pipe for this reason and made finned U type pipe.Complex structure has not only more reduced the heat absorption efficiency of heat collector.Especially obvious in winter; 2. because system is the sealing pressure bearing system, the heat-conducting medium back volumetric expansion of being heated, system will set up the pressure-bearing expansion tank, can produce leakage otherwise be in operation.The pressure-bearing expansion drum in use must running check, otherwise the expansion drum irregular working, and is can build-up of pressure too high, produces leakage.3. owing to be the sealing pressure bearing system, maintenance, additional media fluid have certain technical difficulty, be undertaken by special maintenance mans, and the user can't settle a dispute by the parties concerned themselves.This has just increased the difficulty in user's use.

The utility model content

Technical problem to be solved in the utility model provides a kind of split type two pair circulating solar energy water-heater water tanks of pressing that are used for the separated type solar water heater, the structure that it is used for the heat-conducting medium circulatory system is a gerotor type, is pressure-bearing type and be used for hot water structure partly.Therefore be called " the two circulations of two pressures ".What of heat-conducting medium the user can observe intuitively, can replenish heat-conducting medium very easily simultaneously when heat-conducting medium lacks.

For solving above technical problem, design of the present utility model is: install a tubule that is communicated with atmosphere additional at the top of heating jacket, the heat-conducting medium closed circuit is communicated with atmosphere, makes the loop become the normal pressure loop.

The user can observe easily and the problem of the heat-conducting medium of annotating in order to solve, and presses two circulating solar energy water-heater water tank one sides that a filling jar is installed at split type pair.On filling jar top demountable lid is arranged.At breathing helmet of tip designs of lid, around the breathing helmet four apertures are arranged, the filling jar is communicated with atmosphere.Turn on after the lid heat-conducting medium of can annotating.The red line that indicates of twice is arranged on the filling tank skin, and top indicates the upper limit of line for the filling medium, and it is the lower limit of heat-conducting medium that the bottom indicates line.Can not be higher than the subscript timberline during filling medium, the medium that is in operation is not lower than the subscript timberline.One liquid outlet is arranged at a filling jar bottom, links to each other with the circulation pipe of heat medium with pipe, and during the filling medium, heat-conducting medium pipe thus enters heat collector, chuck and circulating line.At filling jar upper inner face, there is an aperture to link to each other with the blast pipe on heating jacket top.This pipe also has another effect, and is too much as heat-conducting medium that heating circulation system adds, and the back volumetric expansion of being heated, and heat-conducting medium will enter the filling jar by pipeline, the aperture overflow of exhaust.This pipe also has two effects, and the one, when the filling heat-conducting medium, be used to discharge the air of heating circuit.The 2nd, when medium is too much, promptly become overflow ducts, therefore be called the exhaustion spill pipe.

The part that is used for splendid attire hot water is a pressure resistant vessel, rated pressure: 0.6MPa when using hot water, relies on the pressure of running water that hot water is ejected.

Owing to the two circulating solar energy water tanks of above-mentioned split type two pressures have adopted the exhaustion spill pipe, filling jar, the filler pipe that link to each other with the heat-conducting medium loop can make the heat-conducting medium circulatory system is atmospheric pressure state.What of heat-conducting medium in the water heater user can observe intuitively, and can annotate heat-conducting medium very easily to ormal weight.The use of water heater is more reliable, and efficient reaches optimum state.
