手動真空截止閥主要結構特點及用途：

1、真空截止閥主體采用鑄鍛結構，具有平行雙密封副半強制雙向密封，密封面到位運動和楔形塊楔緊運動分步作用實現零泄漏。
2、密封面運動磨擦力小、啟閉輕便，而且密封面磨損有自動補償功能。
3、結構簡單、緊湊、檢修方便，使用壽命長。
4、閥蓋填料室設有真空密封結構，具有自脹壓緊作用，并且密封采用高強膨脹材料密封，使系統與大氣*隔離，具有很好的系統氣密性。
5、本系列閥門連接形式分法蘭、焊接兩種，驅動方式有手動、電動兩種。
該閥門適用于工作溫度≤425℃和≤550℃，工作介質為水、蒸汽或空氣的管路上，作為啟閉裝置；尤其適用于火電廠汽機冷凝和真空負壓系統，起真空隔離密封作用。
