REPLACEABLE FLOW-CONTROL ASSEMBLY FOR USE IN A FLUID FLOW LINE

摘要

A single-piece flow-control assembly is configured to be disposed within a pit assembly in a manner which allows the flow-control assembly to be easily and quickly removed and replaced. The flow--control assembly includes one or more regulators rigidly connected to a mounting assembly having two coupling mechanisms adapted to rigidly mount to at least one of a fluid inlet pipe or a fluid outlet pipe at locations away from the ends of these pipes. The coupling mechanisms provide a sealed engagement between the ends of the flow-control assembly and the fluid inlet pipe and the fluid outlet pipe when the flow-control assembly is properly installed within the pit assembly. A fluid passageway with a 180 degree bend therein may be provided as part of the flow-control assembly so that the coupling mechanisms simultaneously couple to or decouple from the fluid inlet and outlet pipes by movement of the flow-control assembly in one direction.
