◆ 清洁管路

       安装完毕启动系统试运行前，应仔细清洁所有的管件(根据介质类型使用水，空气，蒸汽等)必须清除管件中所有的杂质，尤其是焊渣 有可能会严重损坏阀门的密封座。

        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.

◆ 管路对中

       确保管路已对中，不能靠阀门来纠正对中问题：这有可能造成泄露或操作问题，甚至断裂。

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

◆ 清洁阀座

       安装前，必须确保阀座的清洁，不能有任何的划痕，否则影响密封效果。

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

◆ 避免“水锤”现象

       “水锤”可能造成突然的压力增加,“水锤”造成的阀门的损坏是非常严重的：阀板开裂，阀轴变形，及其它部件的损坏。
       造成“水锤”的原因很多：泵的启动和阀门突然的关闭是常见的原因，注意：在系统启动试运行时，采取所有必要的预防措施，减缓带驱动头的阀门的操作。

       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. 

◆ 小心搬运

       小心阀门的搬运，用吊索要在阀体上，不要在手轮或驱动头上起吊，小心碰撞。

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

◆ 遵守安装方向

       一些阀门使用是有方向性的(如止回阀，平板阀等) , 安装时确认安装方向符合箭头指向或安装指南。

       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. 

◆ 阀门的支撑

       在某些情况下（如结构长度很长，有很重的驱动头等），要预先准备好必要的阀门安装时的支撑架。这样能避免阀门承受过大的压力以致快速损坏操作螺丝和阀座。

        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．

◆ 遵守压紧扭矩

       过大的压紧扭矩对阀门是有害的,这将有可能给阀座带来压痕或造成过快的磨损，尤其对橡胶弹性密封(隔膜阀)。

       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). 

◆ 阀门开启状态焊接

       无论是铸钢还是不锈钢阀门，焊接前应确认阀门是打开的。

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

◆ 谨慎移动阀门

       移动阀门时要小心不要破坏涂层和保护层 , 碰撞及摩擦会破坏涂层招致腐蚀。

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

◆ 在良好的环境中保存阀门

阀门应保存在室内:
避潮,避雨: 以防被腐蚀;
避风,避沙: 以防沙粒或其它硬物进入后将会严重损坏密封座和导轨;
避光,避热: 以防破坏涂层;尤其是对紫外线格外敏感塑料阀门非常有害。含橡胶件的阀门应总在开启状态下保存。
金属阀门应在关闭状态下保存(除非有特殊要求）:避免杂物进人阀体内腔。球阀应在开启状态下保存。保存时保留阀门的各种塑料保护套, 但安装时不要忘记拿去这些保护套。
