A rupture valve is formed on a wall of a container and has a break line along which a wall thickness of the rupture valve is decreased. The break line has an outer edge line which defines an outer edge of an opening region and a plurality of division lines which divide the opening region. The outer edge line has: a first base line and a second base line formed discontinuously such that the first base line and the second base line extend in a first direction, and are formed in a spaced-apart manner in a second direction orthogonal to the first direction; a first support portion forming line formed on a breaking portion of the first base line and extending from the first base line toward the second base line; and a second support portion forming line formed on a breaking portion of the second base line.

A vacuum resistant pressure relief device is (100) disclosed. In one embodiment, a pressure relief device may be an explosion vent. The explosion vent may be provided with one or more ribbed features, which may be radial ribbed features (101).

A safety valve for a housing, for releasing a housing opening of the housing if a defined burst pressure is reached or exceeded in the housing. It is provided here that in a base body of the safety valve including an elastomer, a receptacle groove that is continuous in the circumferential direction is formed for the formfitting accommodation of a retaining web of the housing. The disclosure furthermore relates to an energy accumulator for storing electric energy.

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.

Systems and methods described herein provide for pressure relief valve detection and monitoring. A valve assembly includes a striker and an indicator assembly separated by a diaphragm. The diaphragm may be elastically or permanently deformable. The striker may be connected to a relieve valve disk that releases in response to high fluid pressure at the valve. Movement of the striker may be detected by contact with the diaphragm or by sensors near the diaphragm, which may trigger the indicator assembly to provide an external indication of a valve opening.
