Thermally triggered shut-off device

In the event of a fire, a thermally triggered shut-off device arranged ahead of the regulating valve of a gas-pressure regulator (2) interrupts any further flow of a gas to the consuming unit through the gas-pressure regulator when a certain temperature around the gas-pressure regulator is reached. Coupled with a safety shut-off valve which responds to excess pressure and, if required, lack of pressure, this device represents a very effective additional safety device in the event of fire. A reliable action is achieved by the fact that a spring-loaded valve-closing taper plug (4) is held in a sufficiently open position relative to a valve opening (6) arranged ahead of the regulating valve (5) by a soldered joint (10) that melts when the predetermined closing temperature is reached, and the position of this shut-off device is made visible by an optical indicator (8). ...

Valve including a body delimiting an internal fluid withdrawal and possibly fluid filling circuit, the said internal circuit extending between an upstream end configured to be placed in communication with the storage volume of a tank and a downstream end configured to be connected to a user member withdrawing or distributing the pressurized fluid via the internal circuit, the valve (having, placed in series from upstream to downstream in the internal circuit between the upstream end and the downstream end: an upstream valve shutter, an isolation valve shutter and a dust valve shutter.

Method And Apparatus For Providing Over-Pressure Protection For An Underground Storage Cavern

A method and apparatus is provided which will provide over-pressure protection for an underground storage cavern by reducing the pressure of a pressurized gas stream originating from the an underground storage cavern to form a lower pressure gas stream, monitoring the pressure of a lower pressure gas stream and stopping the flow of the lower pressure gas stream to the pipeline should the pressure of the lower pressure gas stream exceed a threshold value.
