鹭宫 
概要: 
SPR型: 适用于防止冷冻装置过载运行,备有直动型. 
DPR型: 用于冷藏及空调等压缩机吸入,排出的旁通通路. 
检测压缩机排出压力的超负荷,通过旁通通路将其释放至低压侧,以便使压缩机不超负荷. 减少高压开关的开关频度以维护压缩机的运行. 
在春季和秋季的热泵系统的暖气周期中,或当过滤器因异物而阻塞时,该调整阀更能显示其优点.

SPR阀的安装 
    安装于压缩机与蒸发器之间,使出口侧的压力(吸入压力)保持在设定值以下,在负荷急剧增加时,可用于防止因吸入压力上升而引起马达过载.也可象低温装置那样,在压缩机吸入压力低时,将液控阀的入口与高压侧的吐出管连接,由放出气体而使装置工作(液控动作型)
