style="font-size:16px;">閘閥安裝注意事項(xiàng)1.安裝前須檢查閥門腔內(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.用戶在安裝鍛鋼閘閥前，必須校對(duì)閥門型號(hào)，連接尺寸及注意介質(zhì)流向，保證與閥門要求一致性。5.用戶在安裝鍛鋼閘閥時(shí)，必須預(yù)留閥門驅(qū)動(dòng)的必要空間。6.驅(qū)動(dòng)裝置的接線須按線路圖進(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。很多閥門能夠適應(yīng)多種工況，但是如果選擇不合理，閥門的性能和使用壽命會(huì)大打折扣。正確、合理的選擇閥門，首先要了解閥門各零部件的材質(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、閥蓋和閥瓣是閥門主要零件，直接承受介質(zhì)壓力，</span><span style="font-size:16px;">所</span><span style="font-size:16px;">用材料必須符合“閥門的壓力與溫度等級(jí)”的規(guī)定。</span></p><p> <span style="font-size:16px;">閘閥關(guān)閉時(shí)，密封面可以只依靠介質(zhì)壓力來(lái)密封，即只依靠介質(zhì)壓力將閘板的密封面壓向另一側(cè)的閥座來(lái)保證密封面的密封，這就是自密封。大部分閘閥是采用強(qiáng)制密封的，即閥門關(guān)閉時(shí)，要依靠外力強(qiáng)行將閘板壓向閥座，以保證密封面的密封性。運(yùn)動(dòng)方式：閘閥的閘板隨閥桿一起作直線運(yùn)動(dòng)的，亦叫明桿閘閥。通常在升降桿上有梯形螺紋，通過(guò)閥門頂端的螺母以及閥體上的導(dǎo)槽，將旋轉(zhuǎn)運(yùn)動(dòng)變?yōu)橹本€運(yùn)動(dòng),也就是將操作轉(zhuǎn)矩變?yōu)椴僮魍屏?。開(kāi)啟閥門時(shí)，當(dāng)閘板提升高度等于閥門通徑的1：1倍時(shí)，流體的通道完全暢通，但在運(yùn)行時(shí)，此位置是無(wú)法監(jiān)視的。實(shí)際使用時(shí)，是以閥桿的頂點(diǎn)作為標(biāo)志，即開(kāi)不動(dòng)的位置，作為它的全開(kāi)位置。為考慮溫度變化出現(xiàn)鎖死現(xiàn)象,通常在開(kāi)到頂點(diǎn)位置上,再倒回1/2－1圈,作為全開(kāi)閥門的位置。因此,閥門的全開(kāi)位置，按閘板的位置（即行程〉來(lái)確定。有的閘閥閥桿螺母設(shè)在閘板上，手輪轉(zhuǎn)動(dòng)帶動(dòng)閥桿轉(zhuǎn)動(dòng)，而使閘板提升，這種閥門叫做旋轉(zhuǎn)桿閘閥或叫暗桿閘</span><span
