波纹管阀 

　　用波纹管作为阀杆密封元件的阀门。它常用于对阀杆密封要求严格的场合，如用于高真空的场合和核决于波纹管的耐压强度和疲劳强度。 

波纹管截止阀的原工业中。采用波纹管代替普通阀门上的填料函或与填料函并用，可使阀杆部位无泄漏，以防止放射性物质或贵重物质外漏，或保持高真空。波纹管随阀杆的升降而伸缩，其zui高工作压力取理

波纹管密封截止阀采用波纹管密封的设计，*消除了普通阀门阀杆填料密封老化快易泄露的缺点，不但提高了使用能源效率，增加生产设备安全性，减少了维修费用及频繁的维修保养，还提供了清洁安全的工作环境。 

使用优点： 

双重的密封设计（波纹管+填料）若波纹管失效，阀杆填料也会避免； 

外泄漏，并符合密封标准； 

没有流体损失，降低能源损失，提高工厂设备安全； 

使用寿命长，减少维修次数，降低经营成本； 

坚固耐用的波纹管密封设计，保证阀杆的零泄漏，提供无需维护的条件。
