Reducing flexible connector for ship

Abstract

The invention discloses a reducing flexible connector for a ship. The reducing flexible connector comprises a large flange and a small flange. A fixing nut is welded and fixed to the outer surface ofthe inner side of the upper top end of the large flange, an anti-torque rubber bar is installed at the outer top end of the fixing nut, a telescopic rubber bag is installed in the center position of the anti-torque rubber bar, a reducing rubber pipe is installed in the center position of the large flange, an inner ring is installed in the center position inside the small flange, a gasket is installed on the outer surface of the inner ring, an aligning spherical surface is installed on the outer surface of the gasket, cylindrical rollers are in rolling connection with the center position of thealigning spherical surface at equal intervals, an outer ring is installed on the outer surface of the aligning spherical surface, a through hole is cut in the center position of the reducing rubber pipe, a plurality of damping air bags are cut inside the reducing rubber pipe, and the upper and lower top ends of the damping air bags are provided with inflation inlets. The reducing flexible connector for the ship is used for a ship system, reduces nose and vibration, and is convenient to install, flexible to use and convenient to maintain.

Description

technical field [0001] The invention belongs to the technical field of ship mooring connections, and in particular relates to a variable-diameter flexible joint for ship moorings. Background technique [0002] The transportation pipeline joints of water, electricity, chemical industry, and ship berthing systems, due to the corrosion of the transmission medium, the harsh use environment, high moisture and salinity, and large climate temperature differences, the hard-connected metal pipe joints cause the pipes to arch or crack due to thermal expansion and contraction. And because the axial direction, lateral direction and angle are fixed, there is no vibration buffering effect, and the torsional performance is poor. [0003] Most of the existing flexible joints have flanges at both ends, and rubber pipes are arranged in the middle of the two flanges, which do not have good torsional performance and shock and noise reduction functions. Contents of the invention [0004] The ...

[0002] The transportation pipeline joints of water, electricity, chemical industry, and ship berthing systems, due to the corrosion of the transmission medium, the harsh use environment, high moisture and salinity, and large climate temperature differences, the hard-connected metal pipe joints cause the pipes to arch or crack due to thermal expansion and contraction. And because the axial, lateral and angle are fixed, there is no vibration buffering effect, and the torsional performance is poor

[0003] Most of the existing flexible joints are flanges at both ends, and rubber pipes are installed in the middle of the two flanges, which do not have good torsion resistance and shock absorption and noise reduction functions.
