結構特[Te]點及用途
本閥為敞開式設計結構,具有重(Zhong)量輕,易維護(密封膠圈更換、電動裝置維護檢(Jian)查、更換(Huan)、閥門(Men)的局部維護均在外部,不影(Ying)響閥門正常運行),閥門[Men]的運動過程(Cheng)、開關狀态直觀性好[Hao],啟閉(Bi)後檢查完成狀态極(Ji)為方便,具有封閉式不可替代(Dai)的優勢,缺點是(Shi)啟閉時有少量[Liang]的煤氣外漏。壓(Ya)緊傳[Chuan]動機構采[Cai]用(Yong)齒圈[Quan]、齒輪、梯(Ti)形螺紋、絲杆[Gan]副[Fu]同步雙向壓緊。左、右旋(Xuan)梯形螺[Luo]紋絲杆同步壓緊[Jin]的優點是;起[Qi]動力[Li]矩小,螺紋副自鎖[Suo]性好,閥門密封可[Ke]靠闆移動采用銷齒輪傳動機構,不易積[Ji]灰,滿足(Zu)了粉塵多、潤[Run]滑條件差、工[Gong]作環境惡劣的場合使用。
本閥地面可配置防爆型[Xing]控制櫃,實行現場(Chang)控制和遠距離與PLC系(Xi)統連接控制[Zhi],設計距離10米以上。
