Coupling for fluid pipelines comprises two separate connectors closed by spring-biased valves which can be linked so that both valves are open

摘要

The coupling for fluid pipelines comprises a first connector (1) with a fluid channel (4) which can be closed by a valve (5) which is biased towards the closed position by a spring (6). A second, separate connector (2) also has a fluid channel (14) closed by a second valve (15) biased by a second spring (16). A coupler (29) links the connectors and allows the valves, which are both attached to a bar (28) to move to the open position, so that fluid can flow through both channels.
