直连机组在高低区直连供热的应用

Application of Direct Connection Unit to Direct Connection of Heatsupply in High Zone and Low Zone

直连机组可实现高区、低区供热系统的直接连接。对直连机组的工作流程进行分析,探讨加压泵、减压阀、常闭电磁阀的选型方法。结合工程实例,对直连机组的选型及实际应用效果进行了介绍。

The direct connection unit can realize the direct connection of heat-supply systems in high zone and low zone. The workflow of the direct connec- tion unit is analyzed, and the lectotype methods of booster pump, pressure relief valve and normally closed solenoid valve are discussed. The lectotype and actual application effect of the direct connection unit is introduced with a project example.
