楔式闸阀产品概述:
闸阀是作为截断和接通流体使用,在全开时整个流通直通,此时介质运行的压力损失小。闸阀通常适用于不需要经常启闭,而且保持闸板全开或全闭的工况。不适用于作为调节或节流使用。闸阀广泛适用于石油化工,火力发电厂等油品、水蒸气管路上作接通或截断管路中介质的启闭装置。
产品特点:
1、结构紧凑、设计合理、阀门刚性好、通道流畅,流量系数小
2、密封面采用不锈钢和硬质合金,使用寿命长
3、采用柔性石墨填料、密封可靠,操作轻便灵活
4、驱动方式为手动、气动、电动、齿轮传动
5、结构形式为弹性楔式单闸板、刚性楔式单闸板双闸板型式
闸阀执行标准:
设计规范:API600 API603
结构长度:ASME B16.10
连接法兰:ASME B16.5
试验与检验:API598
