Description

Technical Field

[0001] The utility model relates to the technical field of pipe connection, and more specifically to a hose connector. Background Art

[0002] Existing hose connection methods generally include threaded connection, clamp connection, quick connection and welding connection. Clamp connection is suitable for hoses of different materials and sizes. Especially when the materials of the hose and the joint are different, the clamp connection can effectively reduce the damage caused by the material difference, but the clamp connection has poor tightness, cannot withstand high-pressure fluid, and is easy to detach. The quick-connect joint is generally inserted into the hose, and the stability of the connection is enhanced by internal support, but it is also easy to cause the hose and the joint to detach under high pressure conditions. Although the welding connection has strong sealing and tightness, its process requirements are high and it is not easy to operate. The threaded connection is to align and tighten the thread on the hose with the threaded part of the joint. It has strong bearing pressure and good sealing, but it is only suitable for hoses with threads, and the hose and the joint must be selected with suitable models to be connected, resulting in a small scope of use and limited installation.
