Abstract

See full text

This packing chamber is for use within a valve for existing pipelines. The packing chamber can be easily incorporated into existing valves already in use. In the preferred embodiment, the packing chamber is seated between the body of a valve and the yoke tube. The invention creates a primary seal and a secondary seal that acts as a stopper should the first seal fail to ensure fluid is not accidently released to the environment.
