Description

Lead-free copper PPR anti-freezing fission path adapter Technical Field The utility model relates to the technical field of pipeline replacement joints, in particular to a lead-free copper PPR anti-freezing fission path adapter. Background In the fields of building water supply and drainage, heating ventilation and air conditioning, industrial fluid transportation and the like, a reducing adapter is a key component for realizing the connection of pipelines with different pipe diameters. The large-caliber pipeline and the small-caliber pipeline can be effectively butted, smooth transition of fluid in a pipeline system is ensured, and diversified engineering requirements are met. By virtue of the flexible connection mode and the adaptive capacity to different pipe diameters, the reducing adapter is widely applied to various pipeline engineering construction and transformation projects, and the integrity and the functionality of the whole pipeline system are ensured. However, the existing reducing adapter lacks a specific frost crack prevention design, has no structure or technical measures capable of effectively resisting low-temperature frost damage, and is difficult to meet the requirement of safe operation of a pipeline system in a cold region in winter. In winter in cold regions, when the ambient temperature suddenly drops below the freezing point, the water in the pipeline can freeze and expand, and huge expansion pressure is generated. At this time, some reducing adapter joints made of hard plastics or traditional metal materials are easy to crack and break when facing the expansion force generated by water ice formation due to the reduced toughness at low temperature. Once the reducing adapter is frozen and cracked, the pipeline system can leak water, normal water supply or fluid delivery is affected, a series of secondary disasters such as indoor decoration damage, equipment soaking faults and the like can be caused, and great economic loss and inconvenience are brought to users.
