rrr PM型钢制拍门 rrr PM型钢制拍门简介r
rr PM型钢制拍门是安装在给排水和污水处理工程的排水管出口的一种单向阀,用以溢流或止回介质,也可用于各种竖井井盖。仅用于单向水流的圆形、方形或矩形出口,结构简单,工作可靠,无需人力操作,可用法兰连接,也可与预埋件连接固定rrr 按外形构造分圆型拍门和方型拍门。PM型钢制拍门主要由阀体、阀盖、铰链构件组成,有铸铁和碳钢两种材质,其启闭力来自水源压力,不需人工操作。该拍门内的水压大于拍门外侧压力,则开启;反之则关闭,已达到溢流和止回的作用。rrr PM型钢制拍门主要性能:公称压力:0.1mpa适用介质:水、河水、污水、海水适用温度:50rrr PM型钢制拍门参数r
