Blind coupling with non-return valve, e.g. for fire hoses, has blind cover with bore in which non-return valve can be accommodated; bore passes axially through central protrusion

摘要

The blind coupling closes axially and is compatible with a symmetrical hose coupling of two halves, each consisting of a hose nozzle and a rotatable ring (1), or is compatible with the shape of a one-piece fixed coupling. The blind cover (4) has a bore(20) in which a non-return valve (21) can be accommodated. The bore passes axially through a central protrusion.
