◆ 清潔管路

       安裝完畢啟動系統(tǒng)試運行前，應仔細清潔所有的管件(根據(jù)介質(zhì)類型使用水，空氣，蒸汽等)必須清除管件中所有的雜質(zhì)，尤其是焊渣 有可能會嚴重損壞閥門的密封座。

        Before the tests and starting of lhe installations ,carry out the abun- dant rinsing of piping(water ,air ,steam if compatible). It is essential to eliminate all the particles and various objects which could remain in the pipes and particularly welding residues which could definitively damage the valve seat.

◆ 管路對中

       確保管路已對中，不能靠閥門來糾正對中問題：這有可能造成泄露或操作問題，甚至斷裂。

       Check piping alignment. Do not rely on the valves to correct bad alignments:risk of leakage,operating defect or even breaking.

◆ 清潔閥座

       安裝前，必須確保閥座的清潔，不能有任何的劃痕，否則影響密封效果。

       Before assembling,take care that the gasket seats are perfectly clean free from stripes prejudicial to good tightness．

◆ 避免“水錘”現(xiàn)象

       “水錘”可能造成突然的壓力增加,“水錘”造成的閥門的損壞是非常嚴重的：閥板開裂，閥軸變形，及其它部件的損壞。
       造成“水錘”的原因很多：泵的啟動和閥門突然的關(guān)閉是常見的原因，注意：在系統(tǒng)啟動試運行時，采取所有必要的預防措施，減緩帶驅(qū)動頭的閥門的操作。

       A water hammer can generate a rise in pressure of extreme brutality. The damage caused by a water hammer is considerable:butterfly valve disc splits,axes deformed,destroyed various apparatuses. The causes of the water hammers are very varied but generally：the starting of pump and the sudden closing of valve.Attention,when starting the installation or testing ,take all the necessary precautions slow down motorized valves. 

◆ 小心搬運

       小心閥門的搬運，用吊索要在閥體上，不要在手輪或驅(qū)動頭上起吊，小心碰撞。

       Sling valves by the body. Do not hang at the handwheel or the servo-moto. Attention with the shocks. 

◆ 遵守安裝方向

       一些閥門使用是有方向性的(如止回閥，平板閥等) , 安裝時確認安裝方向符合箭頭指向或安裝指南。

       Some valves are one-way(non-return valve ,knife gate valves,etc). Take care of an assembly in conformity with the arrow direction or of the instructions of assembly. 

◆ 閥門的支撐

       在某些情況下（如結(jié)構(gòu)長度很長，有很重的驅(qū)動頭等），要預先準備好必要的閥門安裝時的支撐架。這樣能避免閥門承受過大的壓力以致快速損壞操作螺絲和閥座。

        Before the tests and starting of lhe installations ,carry out the abun- dant rinsing of piping(water ,air ,steam if compatible). It is essential to eliminate all the particles and various objects which could remain in the pipes and particularly welding residues which could definitively damage the valve seat．

◆ 遵守壓緊扭矩

       過大的壓緊扭矩對閥門是有害的,這將有可能給閥座帶來壓痕或造成過快的磨損，尤其對橡膠彈性密封(隔膜閥)。

       It is prejudicial applying higher tightening torque than needed. This can create markings on the seats and ,premature wears particularly for the rubber seat (diaphragm valves). 

◆ 閥門開啟狀態(tài)焊接

       無論是鑄鋼還是不銹鋼閥門，焊接前應確認閥門是打開的。

       Take care, when welding steel or stainless valves ,that the position is open. 

◆ 謹慎移動閥門

       移動閥門時要小心不要破壞涂層和保護層 , 碰撞及摩擦會破壞涂層招致腐蝕。

       Take care of the coatings and protections. To avoid shocks and frictions which ,by destroying the coatings ,create starters of corrosion. 

◆ 在良好的環(huán)境中保存閥門

閥門應保存在室內(nèi):
避潮,避雨: 以防被腐蝕;
避風,避沙: 以防沙粒或其它硬物進入后將會嚴重損壞密封座和導軌;
避光,避熱: 以防破壞涂層;尤其是對紫外線格外敏感塑料閥門非常有害。含橡膠件的閥門應總在開啟狀態(tài)下保存。
金屬閥門應在關(guān)閉狀態(tài)下保存(除非有特殊要求）:避免雜物進人閥體內(nèi)腔。球閥應在開啟狀態(tài)下保存。保存時保留閥門的各種塑料保護套, 但安裝時不要忘記拿去這些保護套。
