Description
技术领域technical field
本实用新型属于可再生的清洁能源利用的技术领域,涉及太阳能真空集热管热水器的构造。更具体地说,本实用新型涉及一种太阳能热水器防热水倒流结构。The utility model belongs to the technical field of renewable clean energy utilization and relates to the structure of a solar vacuum heat collecting tube water heater. More specifically, the utility model relates to a structure for preventing backflow of hot water of a solar water heater.
背景技术Background technique
目前,太阳能热水器在广大城乡得到普遍应用,就节约能源和环境保护来说,其优势极为明显。At present, solar water heaters are widely used in vast urban and rural areas, and their advantages are extremely obvious in terms of energy saving and environmental protection.
但是,一般的太阳能真空集热管热水器为了简化结构,在自来水进水和热水放水管路的结构上,采用的是同一根管路,不再单独设置上水管路。采用一个用水水阀放水,并用冷水水阀和热水水阀进行冷热水的混合。通过控制冷水水阀和热水水阀的开度,控制冷热水的配比来调节水温。在用水结束以后(实际上水箱内还存有大量热水),关闭用水水阀;同时打开冷水水阀和热水水阀,利用自来水的水压,向水箱补充自来水。However, in order to simplify the structure, the general solar vacuum heat collector tube water heater adopts the same pipeline in the structure of the tap water inlet and hot water discharge pipelines, and no separate water supply pipeline is provided. Adopt a water water valve to discharge water, and carry out the mixing of cold and hot water with the cold water water valve and the hot water water valve. By controlling the opening of the cold water valve and the hot water valve, and controlling the ratio of cold and hot water to adjust the water temperature. After the water is finished (in fact, there is still a large amount of hot water in the water tank), close the water valve; open the cold water valve and the hot water valve at the same time, and use the water pressure of the tap water to replenish the tap water to the water tank.
这就会产生一个问题:当自来水停水或水压不足时,水箱内的热水会通过水管及冷水水阀、热水水阀,流到自来水的管路中,产生热水倒流现象。这一现象,在任何楼层均有可能发生,因为水箱高度是一定的,只要自来水的水压小于水箱的压力,均会产生热水倒流。用户一般不可能会注意到这一现象。除非是比较细心的用户,在向水箱补充冷水时,用手去摸一摸自来水管是否发烫。,而且,有时刚开始时正常的,随后自来水的水压下降,这就更难以发现。对用户来说靠人为控制热水倒流难以做到。因此,应该在技术上采取必要的措施。This will cause a problem: when the tap water is cut off or the water pressure is insufficient, the hot water in the water tank will flow into the tap water pipeline through the water pipe, cold water valve, and hot water valve, resulting in backflow of hot water. This phenomenon may occur on any floor, because the height of the water tank is certain, as long as the water pressure of the tap water is less than the pressure of the water tank, backflow of hot water will occur. Users are generally unlikely to notice this phenomenon. Unless you are a more careful user, when adding cold water to the water tank, touch the water pipe with your hand to see if it is hot. , and, sometimes what is normal at first, then the tap water pressure drops, making it harder to spot. It is difficult for users to manually control the backflow of hot water. Therefore, necessary measures should be taken technically.
