手動(dòng)真空截止閥主要結(jié)構(gòu)特點(diǎn)及用途：

1、真空截止閥主體采用鑄鍛結(jié)構(gòu)，具有平行雙密封副半強(qiáng)制雙向密封，密封面到位運(yùn)動(dòng)和楔形塊楔緊運(yùn)動(dòng)分步作用實(shí)現(xiàn)零泄漏。
2、密封面運(yùn)動(dòng)磨擦力小、啟閉輕便，而且密封面磨損有自動(dòng)補(bǔ)償功能。
3、結(jié)構(gòu)簡(jiǎn)單、緊湊、檢修方便，使用壽命長(zhǎng)。
4、閥蓋填料室設(shè)有真空密封結(jié)構(gòu)，具有自脹壓緊作用，并且密封采用高強(qiáng)膨脹材料密封，使系統(tǒng)與大氣*隔離，具有很好的系統(tǒng)氣密性。
5、本系列閥門(mén)連接形式分法蘭、焊接兩種，驅(qū)動(dòng)方式有手動(dòng)、電動(dòng)兩種。
該閥門(mén)適用于工作溫度≤425℃和≤550℃，工作介質(zhì)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(jī)冷凝和真空負(fù)壓系統(tǒng)，起真空隔離密封作用。
