style="text-indent:25px">閥門安裝的一般規(guī)定：1.閥門安裝的位置不應(yīng)妨礙設(shè)備，管道及閥體本身的操作，拆裝和檢修，同時要考慮到組裝外形的美觀。2.水平管道上的閥門，閥桿朝上安裝，或傾斜一定角度安裝，不可手輪向下安裝。高空管道上的閥門、閥桿和手輪可水平安裝，用垂向低處的鏈條遠(yuǎn)距離操縱閥的啟閉。3.排列對稱，整齊美觀；立管上的閥門，在工藝允許的前提下，閥門手輪以齊胸高較適宜操作，一般以距地面1.0—1.2m為宜，且閥桿必須順著操作者方向安裝。4.并排立管上的閥門，其中心線標(biāo)高較好一致，且手輪之間凈距不小于100mm；并排水平管道上的閥門應(yīng)錯開安裝，以減小管道間距。5.在水泵、換熱器等設(shè)備上安裝較重的閥門時，應(yīng)設(shè)閥門支架；在操作頻繁且又安裝在距操作面1.8m以上的閥門時，應(yīng)設(shè)固定的操作平臺。6.閥門的閥體上有箭頭標(biāo)志的，箭頭的指向即為介質(zhì)的流動方向。安裝閥門時，應(yīng)注意使箭頭指向與管道內(nèi)介質(zhì)流向相同。</p><p style="text-indent:25px">閥門安裝注意事項(xiàng)：1.閥門的閥體材料多用鑄鐵制作，性脆，故不得受重物撞擊。2.搬運(yùn)閥門時，不允許隨手拋擲；吊運(yùn)、吊裝閥門時，繩索應(yīng)系在閥體上，嚴(yán)禁拴在手輪、閥桿及法蘭螺栓孔上。3.閥門應(yīng)安裝在操作、維護(hù)和檢修較方便的地方，嚴(yán)禁埋于地下。直埋和地溝內(nèi)管道上的閥門，應(yīng)設(shè)檢查井室，以便于閥門的啟閉和調(diào)節(jié)。4.應(yīng)保證螺紋完整無損，并在螺紋上纏麻、抹鉛油或纏上聚四氟乙烯生料帶，旋扣時，需用扳手卡住擰入管子一端的六角閥體。5.安裝法蘭閥門時，注意沿對角線方向擰緊連接螺栓，擰動時用力要均勻，以防墊片跑偏或引起閥體變形與損壞。6.閥門在安裝時應(yīng)保持關(guān)閉狀態(tài)。對靠墻較近的螺紋閥門，安裝時常需要卸去閥桿閥瓣和手輪，才能擰轉(zhuǎn)。在拆卸時應(yīng)在擰動手輪使閥門保持開啟狀態(tài)后，再進(jìn)行拆卸。如果閘板長時期處于半開關(guān)的狀態(tài)下工作，閘板的密封面會因受介質(zhì)沖刷而變得不嚴(yán)密。</p><div

style="text-indent:25px">閥門注脂時的維護(hù)保養(yǎng)工作：1、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。確保閥門的直角行程。2、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。以便下一次操作時應(yīng)用。3、注脂時，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，及時補(bǔ)充潤滑脂，防止磨損情況發(fā)生。4、注脂時，不要忽略閥桿部位的注脂。閥軸部位有滑動軸套或填料，也需要保持潤滑狀態(tài)，以減小操作時的摩擦阻力，如不能確保潤滑，則電動操作時扭矩加大磨損部件，手動操作時開關(guān)費(fèi)力。檢查閥桿和閥瓣開啟是否靈活，有無卡住和歪斜現(xiàn)象。山西閥門廠家聯(lián)系方式</p><p style="text-indent:25px">分流閥類包括各種分配閥和疏水閥等，其作用是分配、分離或混合管路中的介質(zhì)。山西閥門廠家聯(lián)系方式</p><p style="text-indent:25px">常用的截止閥有以下幾種：(1）角式截止閥；在角式截止閥中，流體只需改變一次方向，以致于通過此閥門的壓力降比常規(guī)結(jié)構(gòu)的截止閥小。(2）直流式截止閥；在直流式或Y形截止閥中，閥體的流道與主流道成一斜線，這樣流動狀態(tài)的破壞程度比常規(guī)截止閥要小，因而通過閥門的壓力損失也相應(yīng)的小了。(3）柱塞式截止閥：這種形式的截止閥是常規(guī)截止閥的變型。在該閥門中，閥瓣和閥座通常是基于柱塞原理設(shè)計(jì)的。閥瓣磨光成柱塞與閥桿相連接，密封是由套在柱塞上的兩個彈性密封圈實(shí)現(xiàn)的。兩個彈性密封圈用一個套環(huán)隔開，并通過由閥蓋螺母施加在閥蓋上的載荷把柱塞周圍的密封圈壓牢。彈性密封圈能夠更換，可以采用各種各樣的材料制成，該閥門主要用于“開”或者“關(guān)”，但是備有特制形式的柱塞或特殊的套環(huán)，也可以用于調(diào)節(jié)流量。山西閥門廠家聯(lián)系方式</p></p><br
