It is used for large-scale smart city industrial buildings to prevent freezing and cracking intelligent pipeline connection equipment

Abstract

The invention discloses an intelligent pipeline connection equipment for anti-freezing and cracking of large-scale smart city industrial buildings, and relates to the technical field of pipeline connection equipment, including a sleeve and a locking assembly arranged on the sleeve. The sleeve is a hollow cylindrical structure , both sides of the sleeve are embedded with pipes, and the middle of the inner wall of the sleeve is fixedly connected with a connecting plate extending to the inside of the sleeve. There is a first cavity between the surface and the inner wall of the pipe, and a sealing assembly is arranged in the first cavity, and there is a second cavity between the outer wall of the pipe and the inner wall of the sleeve, and a vent hole is fixedly connected inside the sleeve, and the vent hole and the second The two cavities communicate with each other, and the present invention provides a storage place for ice cubes to freeze through the first cavity and the second cavity, reduces the pressure on the pipeline connection, and effectively strengthens the sealing of the pipeline connection.

Description

technical field [0001] The invention relates to the technical field of pipeline connection equipment, in particular to an intelligent pipeline connection equipment for anti-freezing and cracking of large-scale smart city industrial buildings. Background technique [0002] Under normal circumstances, substances follow the law of thermal expansion and contraction. However, for water, it has a certain temperature premise. The force becomes weaker, the molecular distance is larger, the volume will become larger, and the ductility of the metal in winter is also weak. When the water freezes, the volume increases, and the water pipe will burst, especially the parts where multiple pipes are connected to each other. Icing occurs at low temperature, causing the pipeline to be easily damaged, and greatly increasing the weight of the pipeline, making the pipeline easy to break. [0003] The Chinese invention patent with the publication number CN105526459A in the prior art discloses a k...
