英国斯派莎克BRV2S直接作用式减压阀

 <*n style="text-indent: 2em; font-family: 宋体; font-size: 12px; line-height: 18px;"> 英国斯派莎克BRV2S<*n style="text-indent: 2em; font-family: 宋体; font-size: 12px; line-height: 18px;">直接作用式减压阀由主阀和导阀两部分组成。 主阀主要由阀座、主阀盘、活塞、缸套、弹簧等零件组成。导阀主要由阀座、阀瓣、膜片、弹簧、调节弹簧等零件组成。通过调节调节弹簧压力设定出口压力，利用膜片传感出口压力变化，通过导阀启闭驱动活塞调节主阀节流部位过流面积的大小，实现减压稳压功能。本产品主要用于蒸汽管路，起减压稳压作用。

减压阀结构紧凑，重量轻，安装简便，易于调试和设定，维修方便。斯派莎克BRV71和BRV73为球墨铸铁直接作用式减压阀，BRV71为螺纹连接，BRV73为法兰连接，主要用于蒸汽系统。结构紧凑，设计简单，表面高质量的无电****涂镍处理。与BRV2系列减压阀相比，BRV71和BRV73内有压力平衡波纹管，可以平衡主阀头上的压差。主阀为平面密封，具有自清洁功能。斯派莎克SRV2直接作用式减压阀，用于蒸汽，压缩空气或其它气体系统。在负载稳定时，可以准确的控制下游压力。SRV2阀体材质为316L奥氏体不锈钢，因而主要应用于洁净蒸汽系统的压力控制，同时也可用于其它传统工业的蒸汽系统。
