Abstract (en)
[origin: CN113775801A] The present invention relates to a thermal pressure relief device (100) for gas pressure accumulators and/or gas pressure accumulator systems, having: a valve unit (110), which can be fluid-connected to the gas pressure accumulator and/or to the gas pressure accumulator system and has at least one fluid path (101) by means of which the gas pressure accumulator and/or the gas pressure accumulator system can be emptied, in particular a gas stored at high pressure in the gas pressure accumulator and/or gas pressure accumulator system can be discharged into the environment, the valve unit (110) having a closure element (111) which can be shifted and/or moved between an open position in which the gas can flow through the fluid path (101) and a closed position in which no gas can flow through the fluid path (101); and a first triggering means (120), which is designed to shift and/or move the closure element (111) into the open position and/or to allow the closure element (111) to shift and/or move into the open position by heat action, in particular when a predefined temperature is reached, wherein the first triggering means (120) is also designed to sense the heat action at least at a further point St2 of the gas pressure accumulator and/or gas pressure accumulator system which is not the installation position St1 of the thermal pressure relief device (100) and/or to sense the heat action at least at two spatially separate points and/or regions, in particular of the gas pressure accumulator and/or gas pressure accumulator system.
