计量供热系统二次管网水力调控装置的适用性分析

Applicability Analysis of Hydraulic Control Devices of the Secondary Pipe Netw ork in Heat Metering System

供热系统为达到高效、节能的目的,都配有相应的水力调控装置,如静态平衡阀、自力式压差控制阀等。随着我国热计量改造工作的迅速开展,室内供暖系统装配恒温阀后热网如何正确配备调控装置是至关重要的。论述了调控装置的调节特性,在不同定压差控制方式下,采用理论计算方法对与恒温阀配合使用的调控装置的适用性进行了分析,对计量供热系统的设计和改造具有指导意义。

In order to achieve high efficiency and energy-saving purpose for heating systems, it is equipped with corresponding adjustment control devices, such as a static balancing valve, self-operate differential pressure control valve. With the rapid progress to carry out the transformation work of heat metering, it is essential for indoor heating systems assembled thermostatic radiator valve to properly choose adjustment devices. This paper discusses the regulatio different constant pressure difference control methods, it n characteristics of the adjustment device. Under analyzes the applicability of the regulation device, using theoretical calculation method, which is used in conjunction with the thermostatic radiator valve. This paper has a guiding significance for the design and retrofit in heat metering system.
