摘要:
A fluid pressure safety relief system for a pressure vessel (10) having a main valve member (46) seating on a nozzle ring (38) under a mechanical force of a predetermined amount resulting from a calibrated counterweight (54). An operating rod (55) is connected between the main valve member (46) and a piston (74) having one side in fluid communication with fluid pressure in the pressure vessel (10). A fluid chamber (78) is provided on the other side of piston (74) and a fluid passage (84) from fluid chamber (78) has an outlet at its upper end (86) closely adjacent the nozzle ring (38). Upon unseating of the valve member (46) from the nozzle (38) fluid flows from the fluid chamber (78) to increase the fluid pressure differential across the piston (74) to assist in the movement of the main valve member (46) to an open position.
摘要(中):
一种用于压力容器(10)的流体压力安全释放系统,其具有主要阀构件(46),其以由校准的配重(54)产生的预定量的机械力而位于喷嘴环(38)上。 操作杆(55)连接在主阀构件(46)和活塞(74)之间,其一侧与压力容器(10)中的流体压力流体连通。 流体室(78)设置在活塞(74)的另一侧,并且来自流体室(78)的流体通道(84)在其紧邻喷嘴环(38)的上端(86)处具有出口。 在阀构件(46)从喷嘴(38)移开时,流体从流体室(78)流出,以增加跨过活塞(74)的流体压力差,以帮助主阀构件(46)移动到 一个开放的职位。
