CENTURY INSTRUMENT隔膜阀830-RV系列介绍
这种独立的弹簧式隔膜减压阀是自动操作的,无需空气压力或其他外部电源即可运行。尺寸为1/2"至8",适用于各种主体材料,衬里和隔膜,压力释放设置为10至150 psig。
非常适用于保护塑料或玻璃管道系统免受过压,管道浪涌和水锤,隔离可能因真空条件而损坏的设备,将液压头保持在泵排放管路中或更换或在危险或腐蚀性过程中保护爆破片。
阀门将在预设压力下释放,然后在安全工作压力恢复后自动重新安装。从原始压力设置调整在以下限制内提供; 如果原始设置为30 psig或更高,则加或减20 psig。如果原始设置为10 psig,则可用调整加20 psig减去0 psig。
830-RV不是弹出式安全阀,因此它不能提供完全弹开式动作,但会在上升压力下逐渐打开,并在下降压力时逐渐关闭。重新密封后,气密封闭通常会产生3至10 psig的压力。低于释放设定压力,取决于设定点是极高还是低。
Model 830-RV Diaphragm Relief Valves
This self-contained, spring loaded diaphragm pressure relief valve is self-operated and requires no air pressure or other outside power source to function. Available in sizes 1/2" through 8" in a wide variety of body materials, linings and diaphragms and with pressure relief settings from 10 to 150 psig.
Ideal for applications such as the protection of piping systems of plastic or glass against over-pressure, pipe line surges and water hammer, to isolate equipment which might be damaged by vacuum conditions, to maintain a liquid head in a pump discharge line or to replace or protect rupture discs in hazardous or corrosive processes.
The valve will relieve at a preset pressure, then reseat itself automatically when safe working pressure is restored. Adjustment from the original pressure setting is provided within the following limits; plus or minus 20 psig. if the original setting is 30 psig. or higher. If the original setting is 10 psig. the adjustment available is plus 20 psig. minus 0 psig.
The 830-RV is not a pop-safety valve and therefore it does not provide full pop-open action but will gradually open on a rising pressure and gradually close on a falling pressure. Upon reseating, bubble-tight closure usually results at 3 to 10 psig. lower than the relieving set pressure depending on whether the set point is extremely high or low.
