Abstract. Thermally-activated pressure relief devices (TPRD) with glass bulbs or fusible alloy are applied to high-pressure hydrogen storage cylinders (HHSC), in order to release hydrogen gas from the cylinder in fire accidents. In this paper, cylinders with different TPRDs were tested in two groups using different bonfire test methods. In group …
1.1 The primary purpose of a pressure or vacuum relief valve is to protect life and property by venting process fluid from an overpressurized vessel or adding fluid (such as air) to prevent formation of a vacuum strong enough to cause a storage tank to collapse. Proper
We can calculate the pump deadhead pressure for the hot and cold conditions: Total dynamic head can be converted to pressure: where Δ p is pressure in psi, h is pump head in ft, and 2.304 is a unit conversion factor. Thus, hot and cold deadhead can be calculated: Hot Deadhead = 100 psig + (425 ft × 0.6/2.304) = 211 psig.
The Basics. A hydraulic accumulator is a pressure vessel containing a membrane or piston that confines and compresses an inert gas (typically nitrogen). Hydraulic fluid is held on other side of the membrane. An accumulator in a hydraulic device stores hydraulic energy much like a car battery stores electrical energy.

You place the relief valve on some piping, facing the pressure vessel or equipment you want to protect. As long as the pressure is below the relief valve''s set pressure, a spring holds the relief valve closed. Once the pressure is exceeded, the relief valve spring will be pushed on, the valve will be forced open, letting some fluid through.

The controller will turn the pump off when the solar storage tank hits an upper limit (default 180F but often set lower to prevent scalding). The collector will continue to heat up, which most systems can tolerate, but can lead to discharge of fluid out a pressure relief valve and premature degradation of the heat transfer fluid.
This stored energy is affected by heat transfer with the surroundings (e.g., fire exposure) and pressure relief valve (PRV) action.
