一说热水采暖,人们就会想到膨胀水箱,好象对于低温热水采暖,不论其补水方式如何都必须安装膨胀水箱一样。对此笔者有不同看法.提出供大家探讨: 膨胀水箱的作用有三:定压、容纳系统中受热膨胀的水量、系统因泄漏而缺水时进行补水。其实热水采暖的定压方式不只是膨胀水箱,还有补给水泵定压、气体定压和蒸汽定压等。当采用补给水泵定压时,只要再配上一只安全
One said hot water heating, people will think of expansion tank, as if for low-temperature hot water heating, regardless of how the way the water must be installed expansion tank. I have different views on this.Proposed for discussion: The role of expansion tank has three: constant pressure, to accommodate the expansion of the system of water, the system due to leakage and lack of water to replenish. In fact, the constant pressure of hot water heating not only expansion tank, as well as supply pump constant pressure, gas constant pressure and steam pressure and so on. When the supply pump constant pressure, as long as the match with a safety
