The invention relates to a pipe joint assembly and a water system air conditioner. The pipe joint assembly comprises a first joint piece and a second joint piece. The second end of the first joint piece is used for being connected with the end of a second pipe piece. The second joint piece comprises a first part and a second part. A rolling structure is arranged between the first part and the second end of the first joint piece. The rolling structure, the first part and / or the second end of the first joint piece are in rolling friction. The second part is used for connecting the second end of the first joint piece with the end of the second pipe piece in a crossover mode. According to the pipe joint assembly, the second joint piece and the first joint piece are not in surface contact, when a torque wrench tightens the second joint piece, the first joint piece cannot rotate along with rotation of the second joint piece, so that force-deformation of a first pipe piece which is connected with the first joint piece is avoided, and the product quality is improved.
Description
technical field [0001] The invention relates to the field of pipe connection, in particular to a pipe joint assembly and a water system air conditioner. Background technique [0002] At present, when the water machine pipelines in the industry are connected to water pumps and other waterway components, most of them are tightened with water pipe joints and joint nuts, and sealed with rubber gaskets. [0003] Such as Figure 1~3 As shown, the water machine pipeline 1' is welded to the water pipe joint 2', and the water pipe joint 2' and the joint nut 3' adopt the joint method. When tightening, the water pipe joint 2' and the joint nut 3' are in surface contact. There is no threaded connection between the water pipe joint 2' and the joint nut 3'. Joint nut 3' is threadedly connected with water pump main body 4'. A sealing gasket is provided between the water pipe joint 2' and the water pump main body 4', and after the joint nut 3' is screwed tightly, the sealing gasket can ac...
