NKJ61H真空截止�主要�(jié)�(gòu)特點及用途：
1、本系列閥門主體采用鑄鍛�(jié)�(gòu)，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(xiàn)零泄��
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(jié)�(gòu)簡單、緊�、檢修方便，使用壽命��
4、閥蓋填料室�(shè)有真空密封結(jié)�(gòu)，具有自脹壓緊作�，并且密封采用高強膨脹材料密封，使系�(tǒng)與大氣完全隔�，具有很好的系統(tǒng)氣密�
5、本系列閥門連接形式分法�、焊接兩種，�(qū)動方式有手動、電動兩��
該閥門適用于工作溫�≤425℃和≤550�，工作介�(zhì)為水、蒸汽或空氣的管路上，作為啟閉裝�；尤其適用于火電廠汽機冷凝和真空�(fù)壓系�(tǒng)，起真空隔離密封作用�
