FLAME ARRESTOR ASSEMBLY

摘要

A flame arrestor assembly configured to extinguish a flame propagating between a process control device and a combustible environment outside the process control device. The flame arrestor assembly includes a flame arrestor and a retaining element. The flame arrestor has a body adapted to be disposed within a fluid flow passageway of the process control device. The retaining element is adapted to be disposed within the fluid flow passageway of the process control device proximate to the flame arrestor, and is configured to securely retain the flame arrestor within the fluid flow passageway of the process control device.
