Abstract

A flow valve having a male flange for joining an adjacent female coupling valve or pipe section to form a continuous fluid conduit. The flow valve having a replaceable flange which is used for connecting one fluid conduit to another to form a continuous flow path where the flange has components which prevent interchangeability. A female coupling valve or pipe section defining a duct for communication of a fluid with a locking arrangement for locking the male flow valve in the adjacent female coupling valve or pipe section. Protrusions are provided on either an inside surface of the female coupling valve or pipe section or on an outside surface of the flow valve flange and corresponding recesses are provided on the other with the recesses and protrusions being cooperatively shaped arranged to allow insertion of the flow valve into the female coupling valve or pipe section to the locking position only when said at least one recess and said at least one protrusion match.

Abstract

A quick-disconnect coupling such as a camlock includes a hollow male plug with an external peripheral groove and a hollow female socket defining a duct for communication of a fluid with a locking arrangement for locking the male plug in the female socket. Protrusions are provided on either an inside surface of the female socket or on an outside surface of the male plug and corresponding recesses are provided on the other with the recesses and protrusion beings cooperatively shaped arranged to allow insertion of the male plug member into the female socket member to the locking position only when said at least one recess and said at least one protrusion match.

• F16L 35/00 - Special arrangements used in connection with end fittings of hoses, e.g. safety or protecting devices
• F16L 37/252 - Couplings of the quick-acting type in which the connection is made by inserting one member axially into the other and rotating it to a limited extent, e.g. with bayonet-action the coupling being co-axial with the pipe the male part having lugs on its periphery penetrating into the corresponding slots provided in the female part
