REXROTH力士樂流量控制閥現(xiàn)貨 力士樂特點; 1.控制閥有各種不同類型,它們的適用場合不同,因此,應根據(jù)工藝生產(chǎn)過程的要求合理選擇控制閥類型。 2.氣動類控制閥分氣開和氣關兩類。氣開控制閥在故障狀態(tài)時關閉,氣關控制閥在故障狀態(tài)時打開??刹捎靡恍┹o助設備組成保位閥或使控制閥自鎖,即故障時控制閥保持故障前的閥門開度 3.氣開和氣關的方式可通過正、反作用的執(zhí)行機構類型和正體、反體閥的組合實現(xiàn),在使用閥門定位器時,也可通過閥門定位器實現(xiàn) 4.各種控制閥結構不同,各有特色。從控制閥應用看,發(fā)展方向如下: a.小型執(zhí)行機構:可降低成本,提高流通能力 . b.套筒導向:采用套筒導向,有利于對中,有利于降低摩擦,有利于降噪,有利于流量特性的互換 c.平衡式閥芯:為降低執(zhí)行機構推力或推力矩,采用平衡式閥芯是重要的,它對系統(tǒng)的動態(tài)性能也有改善 d.一體化閥芯和閥座:為克服雙座閥密封性差的缺點,采用相同材質(zhì)的一體化閥芯和閥座組成閥內(nèi)件,將泄漏量和不平衡力同時減到zui小 . e.簡單流路:流路簡單,流阻減小,不僅可使閥兩端壓損下降,而且可降低成本。 f.密封和摩擦:密封性能和摩擦性能是矛盾的兩方面,控制閥設計中不僅要解決密封問題,對摩擦和壽命等性能指標也必須重視 因此,近年來,填料函和填料結構的研究得到重視,旋轉(zhuǎn)型控制閥得到較廣泛應用 g.降低噪聲:采用多種方式降低控制閥噪聲,例如,采用降噪套筒和閥芯,采用多級閥芯,采用降噪限流板,采用擴展器等 h.采用與管道同直徑的控制閥和限制流通能力的閥內(nèi)件:利于降低閥入口壓力和出口流體流速,不需安裝異徑管等附加管件,有利于降低成本,通過更換流通能力大的閥內(nèi)件,可擴展流通能力,通過選用限制流通能力閥內(nèi)件可糾正計算口徑過大的錯誤 i.在數(shù)字化信息化時代,將較多采用智能閥門定位器或通過數(shù)字控制器等實現(xiàn)非線性規(guī)律,補償被控對象非線性,將較少選用控制閥流量特性來補償被控對象非線性 5.閥內(nèi)件的材料隨溫度變化,因此,應考慮不同溫度下熱膨脹造成的影響,也要考慮在高溫下耐壓等級的變化等,應考慮材料的耐腐蝕性、抗疲勞性等性能。 REXROTH力士樂流量控制閥現(xiàn)貨
