style="font-size:16px;">閘閥安裝注意事項(xiàng)1.安裝前須檢查閥門(mén)腔內(nèi)和密封面等部位，不允許有污物或砂粒附著。2.各連接部位螺栓，要求均勻擰緊。3.檢查填料部位要求壓緊，既保證填料的密封性，也要保證閘板開(kāi)啟靈活。4.用戶(hù)在安裝鍛鋼閘閥前，必須校對(duì)閥門(mén)型號(hào)，連接尺寸及注意介質(zhì)流向，保證與閥門(mén)要求一致性。5.用戶(hù)在安裝鍛鋼閘閥時(shí)，必須預(yù)留閥門(mén)驅(qū)動(dòng)的必要空間。6.驅(qū)動(dòng)裝置的接線(xiàn)須按線(xiàn)路圖進(jìn)行。7.鍛鋼閘閥必須定期保養(yǎng)，不得隨意碰撞及擠壓，以免影響密封。很多閥門(mén)能夠適應(yīng)多種工況，但是如果選擇不合理，閥門(mén)的性能和使用壽命會(huì)大打折扣。正確、合理的選擇閥門(mén)，首先要了解閥門(mén)各零部件的材質(zhì)適應(yīng)的工況，根據(jù)其使用范圍進(jìn)行選擇才能使其發(fā)揮比較好性能。閥體、閥蓋和閥瓣是閥門(mén)主要零件，直接承受介質(zhì)壓力，</span><span
