FLUID PRESSURE RELIEF SYSTEM FOR PRESSURE VESSELS |
摘要 |
<p>A fluid pressure relief system and method for a pressure vessel or tank (10) having a normal vent (16) with a first pilot operated safety valve (18) and an emergency vent (62) having a second pilot operated safety valve (25). A vapor recovery line (20) is connected to relief valve (18) and collected at a vapor storage container (21). A manway (22) on the pressure vessel (10) (shown in Figure 2) defines the emergency vent (62) and a main valve member (66) has a counterweight (74) thereon to urge main valve member (66) to a seated closed position on nozzle (60). The first pilot operated safety valve (18) for the normal vent (16) (is shown in Figure 7) and has a T-shaped body (142) with a main relief valve member (172) at one end of the body (142) mounted for movement in a generally horizontal direction and controlled by a diaphragm (176) at an opposite end of the body (142).</p> |
