Description

technical field [0001] The invention relates to a flexible branch system of a hot water main pipeline and a compatible process for regulating and controlling the thermal expansion and displacement of the hot water main pipeline. Background technique [0002] In order to solve the problems of pipeline thermal compensation and thermal stress, metal compensators or non-metallic compensators are usually used in the design of heating pipelines. Metal compensators are mostly used in closed systems, and non-metallic compensators are mostly used in open systems. For long-distance heat supply and transportation, square compensators, rotary compensators, spherical compensators and arched compensators are often used in metal compensators. Square compensators have large dimensions and harsh installation space, and cannot be installed according to the terrain; Although the rotary compensator and the spherical compensator have a large compensation amount, they have poor operation stabili...
