如果是在一個封閉的水系統中安裝熱水器,按照「關閉系統/熱膨脹」中的規定,安裝一個安全閥或膨脹罐。 -
When a reducing valve is used, it makes a closed system ; therefore, a pressure relief valve must be installed in the downstream side of the regulator to protect equipment against excess pressure which is built up by the expansion of water from the domestic hot water supply tank or heater
如果採用減壓閥,將形成一個封閉系統;因此必須在調節閥的下游位置安裝一個壓力安全閥,以保護設備不會由於室內熱水供應容器或熱水器造成的水膨脹而變得壓力過大。
