Rotary connection between two relatively movable fittings - consists of plug coupler used for pressurised medium hose connection

摘要

A sliding sleeve (38) is secured against displacement by a security element (40), such as a safety ring or retaining pin. Where the rotary connection is used in a pipe subjected to high flow speeds or viscous medium, the normally provided non-return valve can be omitted to reduce the flow resistance. A lubricating grease can be used between the sliding sleeve and one of the parts as protection against foreign bodies. A sealing ring can be inserted between the sliding sleeve and one of the parts. USE/ADVANTAGE - For hydraulic systems handling pressurised water,oil,or gas,with low-cost mfr.and reliable operation.
