Description

Technical Field

[0001] The utility model relates to the technical field of dredging pipe connection, in particular to a dredging hose connector. Background Art

[0002] Dredging hoses are essential equipment in dredging operations. Wear or damage to dredging hoses can cause unplanned downtime during the dredging process, leading to decreased dredging efficiency and project delays, resulting in significant economic losses. Erosion wear and fatigue fracture at hose connections are common forms of abnormal hose damage in dredging operations. Currently, dredging hoses utilize conventional flanges, with the front end of the flange perpendicular to the flange axis. The conveying medium is sealed by the preload of the connecting bolts, using a rubber gasket formed on the front end of the flange and integrated with the wear-resistant rubber layer on the hose's inner wall. To ensure a reliable seal, a high preload is required on the connecting bolts.

[0003] However, the bolts are prone to rust and damage after being soaked in seawater or rainwater for a long time, which may cause gaps in the flange connection and cause leakage of the medium transported in the dredging pipe. In addition, the sealing effect of the existing flange connection is not ideal during use. Therefore, it is necessary to provide a dredging hose connector to solve the problem. Utility Model Content
