Abstract
A valve coupling for joining pipe elements includes a valve housing surrounded by coupling segments. Projections extend from the segments and engage channels in the valve housing. Engagement between the projections and the channels guides the segments as they are drawn together to engage the pipe elements and secures the valve housing between the segments.
Claims40
A valve coupling for joining pipe elements and controlling flow therethrough, said valve coupling comprising:
- a plurality of segments attached to one another end to end and circumferentially surrounding a central space;
- a valve housing captured between said segments;
- a valve closing member movably mounted within said valve housing, said valve closing member movable between an open position permitting flow through said valve housing and a closed position preventing flow there through;
- at least one projection extending from one of said segments into said central space, said at least one projection engaging said valve housing and supporting at least two of said segments in spaced relation;
- attachment members located at opposite ends of each said segment;
- arcuate surfaces positioned on opposite sides of each said segment for engagement with said pipe elements.
