在工程设计中，住宅小区给水水泵扬程大于供暖补水泵扬程，故共用水泵扬程满足给水系统即可。但供暖系统可能超压，应安装自动调节阀。正常情况下不会发生供暖系统对给水系统和水池的混水污染。为确保安全，供暖补水管应安装逆止阀，补水水处理装置安装在逆止阀后，宜选用... In the engineering design, the head of the residential community water supply pump is larger than the head of the heating supplement pump, so the common pump head can satisfy the water supply system. However, the heating system may be overpressure and an automatic regulator should be installed. Under normal circumstances, there will be no pollution of the heating system to the water supply system and the pool. In order to ensure safety, the heating water supply pipe should be installed with check valve, and the water treatment device should be installed after the check valve.
