热水供暖用户与外网的直接连接技术方案探讨

Discussion of Direct Connection Technique between Hot Water Heating Users and Outdoor Network

对于外网水压不符合用户要求而不能采用简单直连的情况,可以在用户入口处采用水泵升压,采用自力式压差控制阀或自身压差控制阀节流降压,采用电控缓闭阀和止回阀在系统停止运行时及时关闭以隔离用户系统和外网等方法,实现用户与外网的直接连接。

Simple direct connection cannot be used when the pressure of outdoor network doesn＇t meet users＇ requirement. Measures can be taken to connect users with outdoor network directly, such as using pump to lift the pressure of user inlet, using self-operated differential pressure controller or self differential pressure controller to reduce pressure and using electronic control slow-closing valve and check valve to close to separate users from outdoor network when the system stops operating.
