产品详细说明: 波纹管阀门概述
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,其最高工作压力取决于波纹管的耐压强度和疲劳强度。
波纹管截止阀的原理
波纹管密封截止阀采用波纹管密封的设计,完全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,并符合国际密封标准;
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。
