Description
Technical field:
The utility model relates to technical field of solar water heaters, particularly relates to a kind ofly can make the collecting plate of flat plate solar water heater and the circulatory system of pipeline row pressure.
Background technology:
At present, along with the development of science and technology and the raising of people's living standard, solar water heater enters huge numbers of families, but in the winter time, the use of northern area solar water heater is subject to the puzzlement of a lot of problem, wherein outdoor water pipe from freezing crack is especially outstanding, in order to address this problem, those skilled in the art develops a variety of solar energy water heater pipe emptier, but all there is a lot of disadvantage, such as, utilize the exhaust-valve be contained on water tank intake-outlet to carry out tube emptying, the water nozzle between exhaust-valve and solar water container still can be frozen to block; If adopt electric heating to carry out the frozen block problem of electricity auxiliary heat preserving method solution water nozzle, need to consume certain electric energy, do not meet energy-conservation principle, and the popularization principle of solar energy is runed counter to.Therefore the most of panel heat collecting system of China adopts the emptying technology of backflow, also can adopt Two-way Cycle, also known as the anti-freeze exercise question of indirect system or electrical secondary system basically resolution system.
But flat plate solar water heater system adopts binary cycle system, its collecting plate and the pipeline circulatory system are installed and are adopted pressure-bearing pattern.Like this, under static state system all possesses the pressure itself of 0.2Mpa.When system works under solar illumination state, along with rising and the water pump periodic duty of temperature, system pressure can reach 0.4Mpa, and in the summer operation time, pressure also can increase sometimes.Such formation lower expansion water tank pressurized, will there is collecting plate pipe fitting and take off card media leakage problem in top tube pressurized, form systemic breakdown.
In order to improve the use safety of existing flat plate solar water heater, increase the stability and high efficiency of existing flat plate solar water heater, the applicant gropes through test of many times, at the safety valve that the height point installation and debugging of pipe-line system are good, controlled pressure is at 0.45Mpa, and like this when system reaches in this pressure limit, the medium that safety valve outlet is about to have more is discharged, and flow back to fluid infusion water tank, do not form waste; Guarantee system trouble free service in controlled range, solves this technical barrier more satisfactoryly.
Utility model content:
The purpose of this utility model is to provide a kind of pipeline circulatory system of flat plate solar water heater, ensures that systemic circulation medium fully makes it keep higher heat transfer efficiency.
The technical scheme that the utility model is taked is as follows:
A kind of pipeline circulatory system of flat plate solar water heater, comprise heat collector feed pipe, heat collector outlet pipe, water pump, expansion tank, heat collector and heat exchanger, water pump is connected between the water inlet end of heat collector and the water side of heat exchanger by heat collector feed pipe, expansion tank is connected between the water side of heat collector and the water inlet end of heat exchanger by heat collector outlet pipe, it is characterized in that: also comprise check-valves, return pipe, fluid infusion water tank, discharge opeing water pipe and safety valve, check-valves is connected between the bottom delivery port of water pump and fluid infusion water tank by return pipe, safety valve is connected between the water side of heat collector and fluid infusion water tank by discharge opeing water pipe, the controlled pressure of safety valve is 0.4 ~ 0.5MPa.
Further, the controlled pressure of safety valve is 0.45MPa.
When this circulatory system works under solar illumination, pipeline reaches the controlled pressure of safety valve along with the rising of temperature and Water Pump Circulation System pressure increase, safety valve is automatically opened and is discharged by the medium had more, flow in fluid infusion water tank, to ensure that the circulatory system is in the work of safe pressure Inner eycle through discharge opeing water pipe.When this circulatory system works in low temperature range, the pressure of circulatory system medium diminishes, circulatory system medium is not enough, therefore need to open check-valves and water pump, water pump is started working, from fluid infusion water tank kind by medium suction heat collector, ensure that systemic circulation medium fully makes it keep higher heat transfer efficiency.
Owing to adding check-valves, return pipe, fluid infusion water tank, discharge opeing water pipe and safety valve in this flat plate solar water heater circulatory system, when the pressure of the circulatory system exceedes the pressure limit of safety valve, safety valve will be opened, the medium had more is entered in fluid infusion water tank through discharge opeing water pipe, the pipe fitting avoiding heat collector takes off the problem of card, dielectric leakage, ensures system trouble free service in controlled range; The setting of check-valves, return pipe and fluid infusion water tank, when system pressure diminishes circulatory mediator deficiency, can by the medium in fluid infusion water tank again suction heat collector, ensure that in systemic circulation have sufficient medium, it is made to keep higher heat transfer efficiency, prevent the waste of resource, enhance the stability in use of flat plate solar water heater, the popularization for flat plate solar water heater has createed more favourable condition.
