摘要
新型波纹管球阀主要用在易燃、易爆和低温有毒工况的苛刻场合,通过填料和波纹管的双重作用实现阀杆密封,达到阀门和外界的零泄露。新型波纹管球采用拨叉结构,把阀杆的直线运动转化为球体的旋转运动,结构紧凑,设计新颖,克服了波纹管截止阀、闸阀及普通轨道式波纹管球阀的缺点,适用于大口径生产。
The new corrugated pipe ball valve is mainly used in flammable,explosive and toxic conditions of low temperature the harsh situation,through the packing and the bellows double role in the realization of valve stem seals,valves and outside reach zero leakage.New corrugated pipe ball uses a fork structure,the valve stem of the linear motion into rotating ball movement,compact structure,novel design,overcome the corrugated pipe cut-off valve,gate valve and common rail type corrugated pipe ball valve disadvantages,suitable for large caliber production.
