Abstract
This article aims to acquaint readers with a designed test bench for direct acting differential pressure control valves. These control valves are used in district heating systems. The conformity of the construction of the test bench with the international standard IEC 60534-2-3:2015 is evaluate and the results of an experimental study of the control valve AVPB DN20 Kvs 6.3 PN16 are present.
Highlights
One reason for the widespread use of control valves for differential pressure control, as a component of district heating network substations is the ability to improve the quality of local temperature control of the heat carrier to the internal installations of the users
The differential pressure control valve is used for balancing the district heating network
The aim of the research is to study the characteristics of differential pressure control valves in the district heating network
Summary
One reason for the widespread use of control valves for differential pressure control, as a component of district heating network substations is the ability to improve the quality of local temperature control of the heat carrier to the internal installations of the users. This is achieved by adjusting the pressure drop on the control valve of the heating circuit and the heat exchanger or by adjusting the pressure drop on the control valve individually. A - control valve authority factor; dPv- differential pressure across the control valve Fig.[1]; dPc - differential pressure across the circuit Fig. 1
