NKZ61H真空铬钼钢法兰式闸阀 安装及选型
之前介绍JIS日标不锈钢截止阀标准，真空闸阀连接形式分法兰、焊接两种，驱动方式有手动、电动两种。真空闸阀适用于工作温度≤425℃和≤550℃，工作介质为水、蒸汽或空气的管路上，作为启闭装置；真空闸阀尤其适用于火电厂汽机冷凝和真空负压系统，起真空隔离密封作用。真空阀是其工作压力低于标准大气压应用于真空系统的阀门。真空阀不仅结构简单、体积小、重量轻、材料耗用省，安装尺寸小，而且驱动力矩小，操作简单、迅速，并且还同时具有良好的流量调节功能和关闭密封特性，真空阀在大中口径、中低压力的拥有广泛的使用领域。当提升锥被顶至顶端时, 阀门内部的结构腔是开放系统且气体流动不受阻碍。一旦提升锥被移动至阀门底部时,橡胶密封圈被压缩密封阀门,而阻绝气体的流通达到密封之效果。
