The utility model discloses a kind of quick-assembly tee ball valves of multidirectional fluid control, it is related to valve dismounting technical field.The ball valve includes tee valve body and valve switch, tee valve body has three valve pipes, and first flared structure is equipped to connect external connecting pipe in each valve pipe end portion, snap ring is equipped on connecting pipe.Valve pipe outer wall is equipped with outer thread and is equipped with the sleeve of threaded sleeve, first flared structure is externally rotatably arranged with multiple circumferentially arranged locking assemblies, each group includes fixed block fixed to valve pipe and locking strip rotatably connected with it by rotating shaft, locking strip has clamping block close to fixed block.Sleeve end portion is equipped with second flared structure, it is covered fixed block and opening end abuts locking strip.Tightening sleeve, second flared structure pushes locking strip to rotate, so that its clamping block extrudes the snap ring of connecting pipe, drives connecting pipe to adhere to valve pipe, and realizes sealing with the water stop ring of junction.Quick, labor-saving installation is realized by the structure, and connection sealing property is significantly improved.

This invention discloses a rapid mooring device and method for dock ships, comprising a base assembly, a rotating component, a sliding force transmission component, a tensioning mechanism, a tie rod assembly, and a mechanical locking assembly. The rotating component and the sliding force transmission component constitute a multi-degree-of-freedom follower mechanism to adapt to changes in the force direction of the mooring line. The tensioning mechanism drives the sliding force transmission component to achieve tensioning and release. The mechanical locking assembly includes a jump plate and a wedge block assembly for rapid coarse adjustment and precise locking of the load. Through the above structure, the small boat can achieve adaptive force adjustment during the floating and bottoming processes of the dock ship, and complete the switch of load from driven bearing to mechanical bearing on the deck. The method includes connection, tensioning, adaptive adjustment, and mechanical locking steps. This solution requires no underwater operation, has high operational safety, high mooring efficiency, and is suitable for rapid mooring and release operations of large-tonnage small boats.
