一．止回閥防水錘的疑問tKJ)'v?正如我們專業(yè)課本中所學(xué)到的，止回閥實際上是造成水錘的根本原因。如果我們設(shè)想水泵是可以倒轉(zhuǎn)的，而且不會破壞，那么在突然停泵之后，返回的壓力波會通過水泵流至吸水池當(dāng)中，能量被安全釋放，因此并不會產(chǎn)生水錘。水流速度的突然變化，即是產(chǎn)生水錘的根本原因。只要水的流速發(fā)生變化，系統(tǒng)壓力必然發(fā)生變化。正是由于止回閥的阻擋作用使得我們會出現(xiàn)典型的“停泵水錘”，止回閥的關(guān)閉使得水流的速度發(fā)生***變化，因此會產(chǎn)生危險的壓力波動。盡管長時期以來，尤其是國內(nèi)的實踐應(yīng)用，通過緩閉或者兩階段關(guān)閉等等方式消除水錘得到過認(rèn)可，但是其適用性還是值得探討。9(B)首先，從非專業(yè)理論的層面上看，通過調(diào)整造成水錘的因素來解決水錘，同時又不作根本的變動，本身就是一種冒險的形為。每個事物都有好與壞的兩方面，人類并不能將壞的方面全部轉(zhuǎn)化成有利的方面，否則就破壞了宏觀的基礎(chǔ)理論，成為正確哲學(xué)的悖論。接下來，并不是緩閉的或者兩階段關(guān)閉的止回閥是“應(yīng)用四海皆準(zhǔn)”的普適定律；因為，水錘是針對全系統(tǒng)而言，并不特指水泵站。因此，止回閥常常不是解決水錘的***答案，工程人員必須進(jìn)行全系統(tǒng)的通盤考慮，綜合解決。蜀山區(qū)普通閥門供應(yīng)</p><p
