Bellow Sealed Valve

Bellow Sealed Valve

     CHAODA group专业研制生产Bellow Sealed Valve等 valve products, CHAODA生产的Bellow Sealed Valve has the features of Good sealing, reliable, safety and long life span.波纹管 gate valve的阀杆采用波纹管及填料双重密封结构,确保阀杆处的无泄漏密封,特别适用于易燃,易爆,有毒及贵重介质的管路。 波纹管采用不锈钢或 Inconel material制造,波纹管密封结构设计合理,耐疲劳,使用寿命长。

CHAODA Valves Group is specialized in manufacturing Bellow Sealed Valve with following good characteristics: good sealing performance, reliable safety guarantee, long life span and etc. Double stem sealing structure is used for Bellow gate valve, i.e. bellow sealing & packing to ensure zero leakage of stem part which is very suitable for pipeline carrying medium with features of inflammable & exposive, toxic or valuable substance. Stainless steel or Inconel material is used for Bellow together with the reasonable structure ensures its long life span.

    波纹管密封球阀主要由阀体,上阀杆,阀杆,波纹管,下阀杆和销等组成。在上,下阀杆上均开有一对螺旋轨道槽(螺旋方向相同),两销固定在阀杆上且销可在上,下阀杆的轨道槽内自由移动。下阀杆和球体相连控制阀门的启闭。

    波纹管密封球阀不同于其他阀门,它采用的是一种较新颖的结构,这种阀门有效地解决了波纹管在球阀密封过程中旋转的问题,利用了阀门两旋向相同的螺旋槽使外界的作用力在传递的过程中经过了三次的转化。Bellow Sealed Valve的两螺旋槽旋向相同,易于加工,装配时不需要配置,有效地达到了现代阀门加工方便,装配简单,工作可靠,操作安全的要求。

Bellow Sealed Valve product description

    Bellow Sealed Valve适用于Class150~Class1500,PN16~PN160的各种管路上,用于截断或接通管路中的介质。选用不同的材质,CHAODA group的Bellow Sealed Valve可分别适用于水,蒸汽,油品,硝酸,醋酸,氧化性介质,尿素等多种介质。Bellow Sealed Valve的驱动方式为手动,蜗轮传动,气动或电动。Bellow Sealed Valve一般采用法兰连接,也可采用对焊连接。

    当上阀杆旋转时,安装在阀杆上的销有旋转的趋势,但阀杆的下部螺旋槽和上部的螺旋槽的旋向相同,将施加-反向的力有阻碍其运动的趋势。根据力的平衡原理对阀杆分析,阀杆将在螺旋槽的作用下仅作上下的伸降运动。又由于波纹管是焊接在阀杆上,阀杆的升降保证了波纹管使用的安全性。

    CHAODA GROUP WENZHOU E-BUSINESS CO.,LTD.is wholly owned subsidiary by Chaoda Group,Professional sales CHAODA group products,CHAODA valve products。CHAODA valves won the reputations of Zhejiang Famous Trademark,Zhejiang Famous Brand,Zhejiang Famous Exporting Brand and also enjoys prizes of 101 National Patent。
