閘閥在養(yǎng)護時則必須處于關(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。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，對潤滑效果進行檢查，黃銅絲扣球閥報價，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，注脂時要先進行排污泄壓，以利于注脂工作的順利進行。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，**后是高點，逐次出脂。如果不按規(guī)律或不出脂，證明存在堵塞，及時進行清通處理。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，黃銅絲扣球閥報價，如果存在開位過盈，可向里調(diào)整開位限位器，黃銅絲扣球閥報價，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><div

閥門常見問題編輯調(diào)節(jié)閥為什么雙密封閥不能當(dāng)作切斷閥使用？雙座閥閥芯的優(yōu)點是力平衡結(jié)構(gòu)，允許壓差大。而它突出的缺點是兩個密封面不能同時良好接觸，造成泄漏大。如果把它人為地、強制性地用于切斷場合，顯然效果不好，即便為它作了許多改進（如雙密封套筒閥），也是不可取的。調(diào)節(jié)閥為什么雙座閥小開度工作時容易振蕩？對單芯而言，當(dāng)介質(zhì)是流開型時，閥穩(wěn)定性好；當(dāng)介質(zhì)是流閉型時，閥的穩(wěn)定性差。雙座閥有兩個閥芯，下閥芯處于流閉，上閥芯處于流開，這樣，在小開度工作時，流閉型的閥芯就容易引起閥的振動，這就是雙座閥不能用于小開度工作的原因所在。什么直行程調(diào)節(jié)閥防堵性能差，角行程閥防堵性能好？直行程閥閥芯是垂直節(jié)流，而介質(zhì)是水平流進流出，閥腔內(nèi)流道必然轉(zhuǎn)彎倒拐，使閥的流路變得相當(dāng)復(fù)雜（形狀如倒S型）。這樣，存在許多死區(qū)，為介質(zhì)的沉淀提供了空間，長此以往，造成堵塞。角行程閥節(jié)流的方向就是水平方向，介質(zhì)水平流進，水平流出，容易把不干凈介質(zhì)帶走，同時流路簡單，介質(zhì)沉淀的空間也很少，所以角行程閥防堵性能好。為什么角行程類閥的切斷壓差較大？角行程類閥的切斷壓差較大，是因為介質(zhì)在閥芯或閥板上產(chǎn)生的合力對轉(zhuǎn)動軸產(chǎn)生的力矩非常小。</p><div

閥門的結(jié)構(gòu)特征是根據(jù)關(guān)閉件相對于閥座移動的方向可分為：（1）截門形：關(guān)閉件沿著閥座中心移動；如截止閥（2）旋塞和球形：關(guān)閉件是柱塞或球，圍繞本身的中心線旋轉(zhuǎn)；如旋塞閥、球閥（3）閘門形：關(guān)閉件沿著垂直閥座中心移動；如閘閥、閘門等（4）旋啟形：關(guān)閉件圍繞閥座外的軸旋轉(zhuǎn)；如旋啟式止回閥等（5）蝶形：關(guān)閉件的圓盤，圍繞閥座內(nèi)的軸旋轉(zhuǎn)；如蝶閥、蝶形止回閥等（6）滑閥形：關(guān)閉件在垂直于通道的方向滑動。如滑按連接方法（1）螺紋連接閥：閥體帶有內(nèi)螺紋或外螺紋，與管道螺紋連（2）法蘭連接閥門：閥體帶有法蘭，與管道法蘭連接。（3）焊接連接閥門：閥體帶有焊接坡口，與管道焊接連接。（4）卡箍連接閥門：閥體帶有夾口，與管道夾箍連接。（5）卡套連接閥門：與管道采用卡套連接。（6）對夾連接閥門：用螺栓直接將閥門及兩頭管道穿夾在一起的連接形式。
