Polymeric rupture disk system

A rupture disk system has a housing defining a central axis, a first axial end defining an axial opening and a second axial end. An airflow pathway extends from the first axial end facing towards the second axial end. A sealing surface is defined about the airflow pathway towards the first axial end...

Beschreibung
Zusammenfassung:	A rupture disk system has a housing defining a central axis, a first axial end defining an axial opening and a second axial end. An airflow pathway extends from the first axial end facing towards the second axial end. A sealing surface is defined about the airflow pathway towards the first axial end. A shield extends across the airflow pathway on the second axial end. Radial openings are defined around the central axis, where the radial openings are positioned between the first and the second axial ends, such that the airflow pathway extends from the axial opening to the radial openings. A rupture disk is coupled to the housing across the airflow pathway. The rupture disk has a polymeric layer. The rupture disk has an unweakened region having a first thickness and a weakened region having a second thickness. A threshold rupture pressure is defined by the weakened region.
