Technical Field
[0001] This utility model relates to the field of secondary heating network technology, specifically a flow regulating device for secondary heating networks with a filtration structure. Background Technology
[0002] The secondary heating network is a crucial component of the heating system, referring to the hot water pipe network from the heat exchange station in the heating community to the entrance of the user's building. It typically consists of two parts: a supply network and a return network. The supply network is responsible for transporting high-temperature hot water from the heat exchange station to the user's building entrance, while the return network is responsible for returning cooled water to the heat exchange station for reheating. The secondary network usually employs a closed-loop piping system, composed of main pipelines, branch pipelines, and distribution pipelines, forming a complex network structure. Within the secondary heating network, situations frequently arise where some users' room temperatures do not meet design flow rates, necessitating flow regulation of the secondary heating network.
[0003] Chinese Patent Publication No. CN219367764U, authorized on July 18, 2023, discloses a flow regulation device for balancing a secondary heating network.
