The invention discloses a flange assembly and a flange device comprising flange assemblies. The flange assembly is used for a pipeline and comprises a flange head and a flange plate. One side of the flange head is connected to the end portion of the pipeline. The flange plate abuts against the side face, towards the pipeline, in the flange head. The flange plate rotationally sleeves the pipeline and / or the flange plate rotationally sleeves the flange head. The flange device comprises the two flange assemblies, wherein the two flange heads are in seal butting, and the two flange plates are connected. According to the flange assembly and the flange device comprising the flange assemblies, the flange heads and the flange plates are of split structures, the flange plates can rotate on the pipeline and the flange heads, angle adjustment between the two flange plates during installation is convenient, the flange connecting installation precision is improved, installing stress generated afterpipeline flange connection is avoided, and the service life of the pipeline is prolonged.
Description
technical field [0001] The invention relates to a flange component and a flange device comprising it. Background technique [0002] There are many hydraulic pipelines on the ship. The hydraulic pipeline is mainly used to transport hydraulic oil and transmit the hydraulic oil to realize the control of the motor and the hydraulic cylinder. The flange is a connecting device for connecting the hydraulic pipeline. This device is to connect the two The root hydraulic pipeline is connected. At present, the flanges used for connection are respectively welded on the connecting ends of the hydraulic pipelines, and finally the connecting ends of the hydraulic pipelines are flanged. When the hydraulic pipeline is assembled, because the flange is welded to the connection end of the hydraulic pipeline, it cannot be disassembled, and the alignment angle of the flange cannot be adjusted. After the hydraulic pipeline is connected, there will be installation stress, which will affect the ins...
