BELLOWS TYPE HIGH PRESSURE FLEXIBLE JOINT WITH SPRING SUPPORTED EXTENSION LIMITING MEMBER

摘要

PURPOSE: A bellows type high pressure flexible pipe unit including an expansion limit member supported by a spring is provided to enable a bellows pipe including a large diameter to endure the environment of high pressure, an extremely low temperature, and a high temperature by installing the expansion limit member supported to the bellows pipe connecting a fluid pipe with the spring. CONSTITUTION: A bellows type high pressure flexible pipe unit comprises an expansion limiting member(100) and a folding type clamping member(200). The clamping member limits expansion of a length direction of a bellows pipe and simultaneously enables the bellows pipe to be bent in a limited range. The expansion limiting member is separated in a circumference direction on an outer boundary surface at predetermined intervals and comprises a plurality of connection units. The expansion limiting member is supported by a spring installed at each valley of the bellows pipe. The interval of the expansion limiting members is connected by an elastic supporting member through the connection unit.
