Pipeline system

Abstract

The invention belongs to the technical field of cold and heat supply systems, and particularly relates to a pipeline system which comprises a heating stove pipeline and a heat pump pipeline. The heat pump pipeline comprises a heat pump water inlet pipe, a heat pump water return pipe, a first connecting pipe and a second connecting pipe; a first control valve is arranged between the heat pump water return pipe and the heating stove water return pipe; a second control valve is arranged between the first connecting pipe and the heat pump water inlet pipe; one end of the second connecting pipe is connected with the heat pump water return pipe, the other end of the second connecting pipe is connected with the heating stove water return pipe, the connecting point of the second connecting pipe and the heating stove water return pipe is located between the second control valve and the heating unit, and a two-way valve is arranged on the second connecting pipe. The use amount of pipelines and valve bodies is reduced, and the layout mode of the pipelines and the valve bodies is simplified, so that the construction difficulty is reduced, and the construction efficiency is improved.
