burkert电磁阀0127
气动活塞执行机构采用压缩空气作动力源,通过活塞的运动带动曲臂进行90度回转,达到使阀门自动启闭。它的组成部分为:调节螺栓、执行机构箱体、曲臂、气缸体、气缸轴、活塞、连杆、万向轴。1.气动阀操作时的启闭方向,一律应顺时针关闭。由于管网中的气动阀,经常是人工启闭,启闭转数不宜过多,就是大口径阀门亦应在200-600转内。为了便于一个人的启闭操作,在管道工压状况下,zui大启闭力矩宜为240N-m。Due to the pneumatic valve in the pipe network, it is often the manual opening and closing, the opening and closing number should not be too much, that is, the large diameter valve should also be inside the 200-600.
