补水方式不仅直接影响热水采暖系统的工作情况;而且还涉及节水、节能和锅炉寿命等问题。为此,建议采用由膨胀水箱、膨胀管自动补水的方式(常用补水方式保留,作为备用)。具体做法是:瓢葫芦自动水箱用φ32—38毫米普通钢管连通,中间要装逆止阁。当系统缺水时,膨胀水箱的水位下降, Replenishment methods not only directly affect the work of hot water heating system; but also related to water conservation, energy saving and boiler life and other issues. To this end, the proposed expansion tank, expansion tube automatic replenishment (commonly used way to retain water as a backup). Specific approach is: automatic calabash φ32-38 mm ordinary steel pipe connected to the middle to install anti-Court. When the system is dry, the water level of the expansion tank drops,
