手动真空截止阀主要结构特点及用途：

1、真空截止阀主体采用铸锻结构，具有平行双密封副半强制双向密封，密封面到位运动和楔形块楔紧运动分步作用实现零泄漏。
2、密封面运动磨擦力小、启闭轻便，而且密封面磨损有自动补偿功能。
3、结构简单、紧凑、检修方便，使用寿命长。
4、阀盖填料室设有真空密封结构，具有自胀压紧作用，并且密封采用高强膨胀材料密封，使系统与大气*隔离，具有很好的系统气密性。
5、本系列阀门连接形式分法兰、焊接两种，驱动方式有手动、电动两种。
该阀门适用于工作温度≤425℃和≤550℃，工作介质为水、蒸汽或空气的管路上，作为启闭装置；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。
