Fluid connector with integrated excess flow valve

摘要

A connector for fluids has a pipe through which the fluid flows. The pipe has a diameter, an inlet end, an outlet end, an expanded area relative to the diameter. The connector also has an excess flow cartridge disposed in the pipe, the excess flow cartridge having a housing for receipt within the diameter, the excess flow cartridge minimizing flow in the pipe if flow exceeds a desired limit, and the excess flow cartridge having a radial opening in a side thereof in register with the expanded area such that flow through the opening flows through the cartridge.

1. A connector for fluids, said connector comprising:
a pipe through which said fluid flows, said pipe having a diameter, an inlet end, an outlet end, an expanded area relative to said diameter, and an excess flow cartridge disposed in said pipe, said excess flow cartridge having a housing for receipt within said diameter, said excess flow cartridge defining a first flow condition to maximize flow from said inlet end to said outlet end and a second flow condition to minimize flow in said pipe if flow exceeds a desired limit, said excess flow cartridge having a radial opening in a side thereof in register with said expanded area such that flow through said opening flows through said cartridge when in said first flow condition, and wherein when flow falls below said desired limit said excess flow cartridge returns to said first flow condition.
