在12mA時定位器反饋桿處于水平位置，其它幾組信號時閥門位置應(yīng)分別在0,25%,75%,**的行程處，且反饋桿的轉(zhuǎn)動角度小于正負(fù)45度。對于零點(diǎn)和滿度的偏差可單獨(dú)調(diào)整相應(yīng)螺釘進(jìn)行修正，正常情況下如果閥門行程和給定信號一一對應(yīng)則表示標(biāo)定完成。閥門關(guān)閉時產(chǎn)生的一個主要問題是如何達(dá)到使閥門嚴(yán)密關(guān)閉的閥座全負(fù)荷。通常的方法是對閥門進(jìn)行標(biāo)定，從而使閉合部件（如閥塞、隔膜、閥板等）恰好定位在閥座上，而不是確認(rèn)閉合部件是否完全靠在閥座上。為了保持設(shè)計泄漏量，避免密封表面受到腐蝕，必須設(shè)計適當(dāng)?shù)拿芊庳?fù)荷。單作用執(zhí)行器通常都采用薄膜式設(shè)計。采用這種設(shè)計方式，使用的彈簧可以減少閥座負(fù)荷，也可以承受全部閉合壓力。典型的雙作用執(zhí)行器采用活塞設(shè)計。采用這種設(shè)計方式，與薄膜式設(shè)計型不同，供應(yīng)壓力不需要進(jìn)行限制，為了達(dá)到較高的閉合壓力，可以應(yīng)用全負(fù)荷供應(yīng)壓力。對于活塞設(shè)計型，壓力越高，閥門的穩(wěn)定性與控制靈敏度就越好。閥門故障分析與排除故障分析原因分析排除故障閥不動作定位器有氣源但沒輸出定位器中放大器的恒節(jié)流孔堵塞按一下清洗件旋鈕進(jìn)行清洗壓縮空氣中有水份，聚積于放大器球閥處用手推動滑閥動作數(shù)次。</p><div

閘閥在養(yǎng)護(hù)時則必須處于關(guān)閉狀態(tài)，確保潤滑脂沿密封圈充滿密封槽溝，如果開位。密封脂則直接掉入流道或閥腔，造成浪費(fèi)。第四、閥門注脂時，常忽略注脂效果問題。注脂操作中壓力、注脂量、開關(guān)位都正常。但為確保閥門注脂效果，有時需開啟或關(guān)閉閥門，對潤滑效果進(jìn)行檢查，確認(rèn)閥門閥球或閘板表面潤滑均勻。第五、注脂時，要注意閥體排污和絲堵泄壓問題。閥門打壓試驗(yàn)后，密封腔閥腔內(nèi)氣體和水分因環(huán)境溫度升高而升壓，注脂時要先進(jìn)行排污泄壓，以利于注脂工作的順利進(jìn)行。注脂后密封腔內(nèi)的空氣和水分被充分置換出來。及時泄掉閥腔壓力，也保障了閥門使用安全。注脂結(jié)束后，一定要擰緊排污和泄壓絲堵，以防意外發(fā)生。第六、注脂時，要注意出脂均勻的問題。正常注脂時，距離注脂口**近的出脂孔先出脂，然后到低點(diǎn)，**后是高點(diǎn)，逐次出脂。如果不按規(guī)律或不出脂，證明存在堵塞，及時進(jìn)行清通處理。第七、注脂時也要觀察閥門通徑與密封圈座平齊問題。例如球閥，如果存在開位過盈，可向里調(diào)整開位限位器，確認(rèn)通徑平直后鎖定。調(diào)整限位不可只追求開或關(guān)一方位置，要整體考慮。如果開位平齊，關(guān)不到位，會造成閥門關(guān)不嚴(yán)。同理，調(diào)整關(guān)到位，也要考慮開位相應(yīng)的調(diào)整。</p></p><br
