閘閥在養(yǎng)護(hù)時(shí)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(shí)，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(shí)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(shí)，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(shí)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(shí)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(shí)，要注意出脂均勻的問題。正常注脂時(shí)，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(shí)進(jìn)行清通處理。第七、注脂時(shí)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(huì)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。新疆消聲止回閥報(bào)價(jià)阿圖什立臥兩用止回閥廠家。</p><div

確保閥門的直角行程。第八、注脂后，一定封好注脂口。避免雜質(zhì)進(jìn)入，或注脂口處脂類氧化。封蓋要涂抹防銹脂，避免生銹。以便下一次操作時(shí)應(yīng)用。第九、注脂時(shí)，也要考慮在今后油品順序輸送中具體問題具體對待。鑒于柴油與汽油不同的品質(zhì)，應(yīng)考慮汽油的沖刷和分解能力。在以后閥門操作，遇到汽油段作業(yè)時(shí)，及時(shí)補(bǔ)充潤滑脂，防止磨損情況發(fā)生。第十、注脂時(shí)，不要忽略閥桿部位的注脂。閥軸部位有滑動(dòng)軸套或填料，也需要保持潤滑狀態(tài)，以減小操作時(shí)的摩擦阻力，如不能確保潤滑，則電動(dòng)操作時(shí)扭矩加大磨損部件，手動(dòng)操作時(shí)開關(guān)費(fèi)力。第十一、有些球閥閥體上標(biāo)有箭頭，如果沒有附帶英文FIOW字跡，則為密封座作用方向，不作為介質(zhì)流向參考，閥門自泄方向相反。通常情況下，雙座密封的球閥具有雙向流向。第十二、閥門維護(hù)時(shí)，也要注意電動(dòng)頭及其傳動(dòng)機(jī)構(gòu)中進(jìn)水問題。尤其在雨季滲入的雨水。一是使傳動(dòng)機(jī)構(gòu)或傳動(dòng)軸套生銹，二是冬季凍結(jié)。造成電動(dòng)閥操作時(shí)扭矩過大，損壞傳動(dòng)部件會(huì)使電機(jī)空載或超扭矩保護(hù)跳開無法實(shí)現(xiàn)電動(dòng)操作。傳動(dòng)部件損壞，手動(dòng)操作也無法進(jìn)行。在超扭矩保護(hù)動(dòng)作后，手動(dòng)操作也同樣無法開關(guān)，如強(qiáng)行操作，將損壞內(nèi)部合金部件。</p><p> 5、逐個(gè)零部件用無紡布進(jìn)行擦干，不能有線毛等留存部件表面，或者用潔凈的氮?dú)膺M(jìn)行吹干；6、用無紡布或者精密濾紙沾分析純酒精對逐個(gè)零部件進(jìn)行擦拭，直至沒有臟色。閥門日常保養(yǎng)編輯1、閥門存放環(huán)境需注意，應(yīng)存放在干燥通風(fēng)的室內(nèi)，且堵塞通路兩端。2、閥門應(yīng)定期檢查，并其上的污物，涂抹涂防銹油在其表面。3、安裝應(yīng)用后的閥門，應(yīng)對其進(jìn)行定期檢修，以確保其正常工作。4、應(yīng)查看閥門密封面是否磨損，并根據(jù)情況進(jìn)行維修或更換。5、檢查閥桿和閥桿螺母的梯形螺紋磨損情況、填料是否過時(shí)失效等，并進(jìn)行必要的更換。6、應(yīng)對閥門的密封性能進(jìn)行試驗(yàn)，確保其性能。7、運(yùn)行中的閥門應(yīng)完好，法蘭和支架上的螺栓齊全，螺紋無損，沒有松動(dòng)現(xiàn)象。8、如手輪丟失，應(yīng)及時(shí)配齊，而不能夠用活扳手代替。9、填料壓蓋不允許歪斜或無預(yù)緊間隙。10、如果閥門使用環(huán)境較為惡劣，易受雨雪、灰塵、風(fēng)沙等污物沾染，則應(yīng)該為閥桿安裝保護(hù)罩。11、閥門上的標(biāo)尺應(yīng)保持完整、準(zhǔn)確、清晰，閥門的鉛封、蓋帽。12、保溫夾套應(yīng)無凹陷、裂紋。13、運(yùn)行中的閥門，避免對其敲打，或者支撐重物等。烏魯木齊黃銅絲扣球閥哪家好。</p><div

同時(shí)與閥門的壓力、溫度及介質(zhì)的濃度等諸因素有著一定內(nèi)在聯(lián)系。閥門的流道面積與流速、流量有著直接關(guān)系，而流速與流量是相互依存的兩個(gè)量。當(dāng)流量一定時(shí)，流速大，流道面積便可小些；流速小，流道面積就可以大些。反之，流道面積大，其流速??；流道面積小，其流速大。介質(zhì)的流速大，閥門通徑可以小些，但阻力損失較大，閥門易損壞。流速大，對易燃易爆介質(zhì)會(huì)產(chǎn)生靜電效應(yīng)，造成危險(xiǎn)；流速太小，效率低，不經(jīng)濟(jì)。對粘度大和易爆的介質(zhì)，應(yīng)取較小的流速。油及粘度大的液體隨粘度大小選擇流速，一般取～2m/s。一般情況***量是已知的，流速可由經(jīng)驗(yàn)確定。各種介質(zhì)常用流速見表2-2。通過流速和流量可以計(jì)算閥門的公稱通徑。閥門通徑相同，其結(jié)構(gòu)型式不同，流體的阻力也不一樣。在相同條件下，閥門的阻力系數(shù)越大，流體通過閥門的流速、流量下降越多；閥門阻力系數(shù)越小，流體通過閥門的流速、流量下降越少。常見介質(zhì)的流速見表2-2。表2-2各種介質(zhì)常用的流速表液體名稱使用條件流速（m/s）液體名稱使用條件流速（m/s）飽和蒸汽DN＞200DN=200～100DN＜10030～4025～3515～30乙炔氣ρ＜（表壓）ρ＜（表壓）ρ＜。阿克蘇絲扣閘閥廠家。巴州雙向蝶閥</p><p
