一．止回閥防水錘的疑問tKJ)'v?正如我們專業(yè)課本中所學到的，止回閥實際上是造成水錘的根本原因。如果我們設想水泵是可以倒轉(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)的實踐應用，通過緩閉或者兩階段關閉等等方式消除水錘得到過認可，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理論，成為正確哲學的悖論。接下來，并不是緩閉的或者兩階段關閉的止回閥是“應用四海皆準”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，工程人員必須進行全系統(tǒng)的通盤考慮，綜合解決。</p><p> 閘閥也叫閘板閥,是一種***使用的閥門。它的閉合原理是閘板密封面與閥座密封面高度光潔、平整一致,相互貼合,可阻止介質(zhì)流過,并依靠頂模、彈簧或閘板的模形,來增強密封效果。它在管路中主要起切斷作用。它的優(yōu)點是:流體阻力小,啟閉省勁,可以在介質(zhì)雙向流動的情況下使用,沒有方向性,全開時密封面不易沖蝕,結構長度短,不僅適合做小閥門,而且適合做大閥門。閘閥按閥桿螺紋分兩類,一是明桿式,二是暗桿式。按閘板構造分,也分兩類,一是平行,二是模式。2.截止閥截止閥,也叫截門,是使用*****的一種閥門,它之所以廣受歡迎,是由于開閉過程中密封面之間摩擦力小,比較耐用,開啟高度不大,制造容易,維修方便,不僅適用于中低壓,而且適用于高壓。它的閉合原理是,依靠閥杠壓力,使閥瓣密封面與閥座密封面緊密貼合,阻止介質(zhì)流通。截止閥只許介質(zhì)單向流動,安裝時有方向性。它的結構長度大于閘閥,同時流體阻力大,長期運行時,密封可靠性不強。截止閥分為三類:直通式、直角式及直流式斜截止閥。3.蝶閥蝶閥也叫蝴蝶閥,顧名思義,它的關鍵性部件好似蝴蝶迎風,自由回旋。蝶閥的閥瓣是圓盤,圍繞閥座內(nèi)的一個軸旋轉(zhuǎn),旋角的大小,便是閥門的開閉度。蝶閥具有輕巧的特點,比其他閥門要節(jié)省材料,結構簡單,開閉迅速。在建立有限元模型時，將閥體、閥蓋和閘板作為一個整體進行建模，忽略它們之間的連接螺栓。</p><div

1、填料函更換。填料函更換時應采用同類型的填料函，更換時應小心將填料勾出，正確拆除填料，防止對閥桿造成損傷。新填料函的安裝應按照說明書要求，切口應錯位，防止閥桿的螺紋對填料的刮傷，填料的壓緊力應均勻和合適，防止造成應力和增大摩擦力。 </p> <p> 2、傳動部件的更換。氣動閥門和附件中的傳動部件如果部分磨損可進行部件更換、修復等。在更換和修復后應保證傳動靈活，傳動間隙盡量小。 </p> <p> 3、氣動放大器的清洗。因儀用壓縮空氣內(nèi)的污物造成氣動放大器的節(jié)流孔堵塞時應對節(jié)流孔進行清洗，可采用合適的鋼絲進行疏通和清洗?；匮b時，放大器膜片應受力均勻，防止造成堵塞或泄漏?？赏ㄟ^調(diào)節(jié)鋼珠的壓緊力調(diào)整放大器增益，防止共振。閘板與閥體內(nèi)壁面形成的擴壓空間，兩次截流所產(chǎn)生的噴流噪聲在此空間相互作用，形成大量的聲渦。五河儀表閥門廠家</p><p
