Abstract
Described herein is a structure for attachment of two parts of a valve structure in a pressure-tight leakproof relationship, which employs a minimum number of parts and may be quickly disassembled, but which is nonetheless strong, rugged, and durable. This structure includes a first member having two pairs of spaced-apart lugs protruding in a direction generally parallel to the axis of an opening in the first member. A second member is provided which extends into the opening and includes two ears, each ear being adapted for placement between two lugs. The lugs are provided with matching transverse holes, whereby a bolt or pin may be placed through one lug of a pair, then over a portion of an ear, then into the second lug of the pair for securing the two members together in a predetermined relationship. Means are provided for detection of internal pressure in the valve to prevent disassembly thereof prior to removal of the pressure.
