What are the advantages of marine connectors

marine connectorIt is an important part of the underwater production system, and its reliability directly affects the reliable operation of the underwater production system. As the core equipment of connecting underwater structures, once the connector is destroyed, it will lead to seal failure and leakage accident. Therefore, in the past two years, the production of marine connection has been paid more and more attention. So, what are the advantages of marine connectors?

1. Easy to use

When the marine connector is used, first make the flange of the loading and unloading arm joint close to the flange of the cargo ship manifold to the allowable connection range. For the wedge type, manually rotate the wedge with special tools to make the slope follow and compress the two connecting flanges to achieve sealing connection to transmit various liquids and gas media. For the connection claw type, first rotate the connection claw to the positive direction of the flange and then rotate the lock nut behind the connection claw to make the two connecting flanges tightly to achieve sealing connection; when the loading and unloading of materials is completed, when the loading and unloading arm is separated from the cargo ship, the above actions need to be repeated in reverse. Stable performance of the marine connector is more convenient to use.

2. Simple structure

Marine connector structure is relatively simple. The marine connector structure system consists of the following parts, namely, the lower joint of the base, the upper joint of the jaw and the anti-loose structure. During docking, the locking structure is driven by the driving structure to apply a pre-tightening force to the upper and lower flanges and the sealing ring, so that the connector is sealed and a complete closed cavity is formed.

3. Strong anti-loosening structure

Marine connectors may bend and deform the anti-loosening box, anti-loosening post and chain support shaft due to external loads. The anti-loosening body may be worn by accidental extrusion, which is mainly reflected in the wear of the working inclined surfaces of the locking block, the unlocking block and the triangular block, which better protects the normal connection of the hull. Good quality marine connectors generally use automatic operation mode.

Through the quantitative analysis of the fault tree of the marine connector structure, the reliability curve of the marine connector structure and the reliable life curve of the long-term operation of the underwater connector are obtained. It can be inferred that the time of the underwater connector structure failure may occur, which has a certain guiding significance for the actual operation, and will be widely put into production in the future.
