产品描述
1、结构简单:气动蝶阀由阀体、阀座、阀板、气动执行器及连接件组成。结构紧凑,安装方便。

2、流量可调:通过调节气动执行器的开度,可以实现对流体的精确控制,调节流量。

 

3、密封性能高:阀座采用三偏心结构设计,与阀板接触面积小,密封性能好,可有效防止泄漏。

 

4、耐腐蚀性强:阀体、阀板通常采用耐腐蚀材料制成,能适应各种腐蚀性介质的工作环境。

 

5、快速启闭:气动执行器具有快速响应的特点,可以快速启闭阀门,适用于需要频繁操作的场合。

偏移01

阀杆的轴位于密封面的背面,与中线蝶阀的结构不同,使密封面脱离阀杆。第一偏置结构使海面能够连续、完整、紧密地接触座椅。

03
偏移02

阀座锥轴偏离阀杆轴线中心线,消除了整个关闭和开启过程中的摩擦力,达到整个阀座环绕一致压缩的密封效果。

04
偏移03

中心线偏离管道中心线,使阀门免受阀门启闭的干扰。同时,第二偏置结构可以使自压密封作用使密封比平常更紧密。

※ 全金属密封系统

密封圈完全由金属材料制成,无夹层,包括聚四氟乙烯、石墨等非金属材料。在全开或半开状态下,阀门密封圈不会因高速介质的冲刷而损坏。阀座堆焊司泰莱等耐磨合金,明显提高了阀门的使用寿命。

※双向密封可靠,启闭力矩小

双向金属密封蝶阀,通过优化进出口两侧受力设计,使阀瓣近似平衡,双向阀门进出口达到可靠的密封性能,同时有效降低阀门开启力。

※ 三偏心全金属密封系统

三偏心结构使阀门启闭时密封圈与阀座迅速接触或分离,无摩擦,大大延长了阀门的使用寿命。

※ 动态负载填料

阀杆和填料基于微泄漏(氦气检测)设计,填料压盖碟形弹簧具有自动补偿功能。

※ 防火结构设计,防爆阀杆设计

※ 通用安装支架(ISO5211标准安装平台)

※ 可更换阀座和阀瓣密封件且可互换

传统的硬密封蝶阀,阀座和阀体连为一体,而我们新型硬密封蝶阀的阀瓣和阀座环可以单独拆卸直接更换,大大降低了阀门的维护成本。 (见下图对比)
