系列双关断旋塞阀
Published: 2012-10-31 | Browse: 2266 【Close this page
产品简介:
系列双关断旋塞阀是为需要严密密封(零泄漏)以及双关断并具有泄放功能 (DBB)的应用而设计的高性能阀门,适用于各种需要严密密封的场合,包括贮罐隔离、多产品管汇、计量校准回路、油站码头、海上平台、精确混合装置、机场加油等系统。
产品特点:
• 采用独特的密封件伸缩结构设计,旋塞旋转过程中密封面完全脱开,消除了密封面间的摩擦和磨损,密封件使用寿命长并确保每次完全密封;
• 采用楔形旋塞主动式密封设计,密封安全可靠;
• 采用上、下游独立的直接硫化成型的橡胶软密封与金属硬密封结合设计,满足了上、下游同时严密关断和耐火要求,并可在线实时进行密封检测;
• 旋塞无需润滑,对介质无污染;
• 顶端和底部双向开启结构设计,无需从管线上拆下即可在现场对内部零部件进行快速维修或更换,维护方便;
• 多种中腔压力泄放装置,满足不同应用场合需求;
• 采用专利排污结构,可方便地将阀门底部污物排泄,确保阀门的长期可靠运行。
