摘要： 为满足热用户的用热需求,提高供热质量,减少能源浪费,避免一、二次管网出现热力失调现象就必须要保证二次管网的热力平衡。保证二次管网的热力平衡的实质是控制二次管网各热用户的流量。文中以沧州市某小区供热工程为例,采用自力式流量控制阀调节各热用户流量的方法实现了二次管网的热力平衡。通过对该项目的分析研究,基于热用户流量控制的二次管网平衡调节是解决供热管网热力失调、节能降耗的有效途径,同时提高了整个工程项目的供热质量,降低了运行成本。通过对该项目的应用分析,为同类型热网实现智能化提供技术支持。

Abstract: In order to meet the heat demand of the heat users,improve the quality of heat supply,reduce the energy waste and avoid thermal imbalance in primary and secondary pipe network,it is necessary to ensure the hydraulic balance of the secondary network.The essence of ensuring the thermal balance of the secondary pipe network is to control the flow rate of each heat user.Taking a district heating project in Cangzhou as an example,the self-operated flow control valve is used to regulate the flow of each heat consumer to achieve the hydraulic balance of the secondary pipe network.Through the analysis and research of the project,it is concluded that the secondary network balance adjustment based on heat user flow control is an effective way to solve the hydraulic imbalance of the heat network,save energy and reduce consumption.At the same time,it improves the heating quality and reduces the operation cost.Through the application analysis of the project,it provides technical support for the realization of intelligence of the same type heat-supply network.

Key words: secondary network, hydraulic balance, self-operated flow control valve, energy saving
