1、填料函更換。填料函更換時(shí)應(yīng)采用同類(lèi)型的填料函，更換時(shí)應(yīng)小心將填料勾出，正確拆除填料，防止對(duì)閥桿造成損傷。新填料函的安裝應(yīng)按照說(shuō)明書(shū)要求，切口應(yīng)錯(cuò)位，防止閥桿的螺紋對(duì)填料的刮傷，填料的壓緊力應(yīng)均勻和合適，防止造成應(yīng)力和增大摩擦力。 </p> <p> 2、傳動(dòng)部件的更換。氣動(dòng)閥門(mén)和附件中的傳動(dòng)部件如果部分磨損可進(jìn)行部件更換、修復(fù)等。在更換和修復(fù)后應(yīng)保證傳動(dòng)靈活，傳動(dòng)間隙盡量小。 </p> <p> 3、氣動(dòng)放大器的清洗。因儀用壓縮空氣內(nèi)的污物造成氣動(dòng)放大器的節(jié)流孔堵塞時(shí)應(yīng)對(duì)節(jié)流孔進(jìn)行清洗，可采用合適的鋼絲進(jìn)行疏通和清洗?；匮b時(shí)，放大器膜片應(yīng)受力均勻，防止造成堵塞或泄漏。可通過(guò)調(diào)節(jié)鋼珠的壓緊力調(diào)整放大器增益，防止共振。碭山塑料閥門(mén)閘閥銅螺母與彈性閥門(mén)采用嵌入式接合，使二者緊密結(jié)合成為一體，不因水流動(dòng)造成震動(dòng)而產(chǎn)生松動(dòng)或損壞現(xiàn)象。</p><div

3、電磁換向閥利用電磁鐵的通電吸合與斷電釋放而直接推動(dòng)閥芯來(lái)控制液流方向。它是電氣系統(tǒng)和液壓系統(tǒng)之間的信號(hào)轉(zhuǎn)換元件。電磁換向閥是利用電磁鐵吸力推動(dòng)閥芯來(lái)改變閥的工作位置。因?yàn)樗梢钥刂菩盘?hào)發(fā)送到一個(gè)按鈕開(kāi)關(guān)，行程開(kāi)關(guān)，限位開(kāi)關(guān)，壓力繼電器，使用操作簡(jiǎn)單，易于實(shí)現(xiàn)自動(dòng)化，所以***應(yīng)用。電磁換向閥的作用是它可以改變控制液流的方向，從而改變液動(dòng)換向閥的位置。由于操縱液動(dòng)換向閥的液壓推力可以很大，所以主閥可以做得很大，允許有較大的流量通過(guò)。這樣用較小的電磁鐵就能控制較大的液流。電磁換向閥工作原理是，通過(guò)電磁鐵控制滑閥閥芯的不同位置，以改變形油液的流動(dòng)方向。變換閥心在閥體內(nèi)的相對(duì)工作位置，使閥體各油口連通或斷開(kāi)，從而控制液壓執(zhí)行元件（如液壓桿、液壓馬達(dá)）的換向或啟停。當(dāng)電磁鐵斷電時(shí)，滑閥由彈簧保持在中間位置或初始位置（脈沖式閥除外）。若推動(dòng)故障檢查按鈕可使滑閥閥芯移動(dòng)。4、其它閥門(mén)按閥的工作位置分類(lèi)閥的工作位置稱(chēng)為“位”，有幾個(gè)切換工作位置的閥就稱(chēng)為“幾位”閥。經(jīng)常使用的有“二位”閥和“三位”閥。閥在未加控制信號(hào)或**作時(shí)所處的位置稱(chēng)為零位。按閥的接口數(shù)目分類(lèi)閥的接口（包括排氣口）稱(chēng)為“通”。</p><p> 一．止回閥防水錘的疑問(wèn)tKJ)'v?正如我們專(zhuān)業(yè)課本中所學(xué)到的，止回閥實(shí)際上是造成水錘的根本原因。如果我們?cè)O(shè)想水泵是可以倒轉(zhuǎn)的，而且不會(huì)破壞，那么在突然停泵之后，返回的壓力波會(huì)通過(guò)水泵流至吸水池當(dāng)中，能量被安全釋放，因此并不會(huì)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(huì)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(huì)產(chǎn)生危險(xiǎn)的壓力波動(dòng)。盡管長(zhǎng)時(shí)期以來(lái)，尤其是國(guó)內(nèi)的實(shí)踐應(yīng)用，通過(guò)緩閉或者兩階段關(guān)閉等等方式消除水錘得到過(guò)認(rèn)可，但是其適用性還是值得探討。9(B)首先，從非專(zhuān)業(yè)理論的層面上看，通過(guò)調(diào)整造成水錘的因素來(lái)解決水錘，同時(shí)又不作根本的變動(dòng)，本身就是一種冒險(xiǎn)的形為。每個(gè)事物都有好與壞的兩方面，人類(lèi)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(lái)，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?yàn)?，水錘是針對(duì)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(pán)考慮，綜合解決。閘閥的承壓邊界主要包括閥體、閥蓋和閘板，力學(xué)特性上分析，認(rèn)為閥體、閥蓋和閘板作為一個(gè)整體來(lái)承受內(nèi)壓。</p><div
