特点:
瓣与阀体密封面之间无相对滑动,因而磨损与
启闭时,阀瓣行程小,因而德国力士乐
流体阻力大,因阀体内介质通道较曲折,流体
,制造与维修都较方便。
密封面不易磨损及擦伤,密封性好,启闭时阀
REXROTH截止阀高度比闸阀小,但结构长度
比闸阀长。
启闭力矩大、启闭较费力,启闭时间校长。
阻力大,动力消耗大。
注意事项:
高温、高压介质的管路或装置上宜选用截止阀
。即对压力损失考虑不大的地方。 城市建设
中的供水、供热工程上,公称通经较小的管路
。如火电厂、核电站,石油化工系统的高温、
高压管路上。管路上对流阻要求不严的管路上
,可选用截止、平衡阀或柱塞阀,如公称通经
小于150mm的管路上
