【产品说明】
进口固定高压球阀—美国威盾VTON,适用于Class 150~2500LB,工作温度-28~300℃的石油、化工、火力电站等各种工况的管路上,其安全、耐恶劣环境性等的设计均已进行特殊考虑,适用介质为:水、蒸汽、油品、硝酸、醋酸、尿素等腐蚀性和强氧化性介质。操作方式有:手动、气动、电动、液动和气液联动等。
进口固定高压球阀特点:
1、阀门中腔停滞的压力异常超过弹簧的预紧力时,阀座后退脱离球体,达到自动泄压的效果,卸压后阀座自动复位。 2、当万一发生火灾或由于异常升温使阀座密封圈烧损或软化时,在弹簧和介质压力作用下,使支撑圈球面部位和球体形成金属对金属接触,达到暂时密封作用,阻止了火灾进一步扩大,符合API 6FA的规定。 3、填料压盖部位密封采用PTFR填料和0形密封圈双重密封圈,特别适用于气体介质,填料装在填料盘内,可随时采用摩擦系统低的新型SF型自润滑滑动轴衬,减低操作力矩。
