：一、閥門安裝的一般要求（l）閥門安裝位置應(yīng)不妨礙設(shè)備、管路及閥門本身的操作和檢修。最適宜的安裝高度為距操作面。當(dāng)閥門手輪中心的高度超過操作面2m時(shí)，對(duì)于集中布置的閥組或操作頻繁的單獨(dú)閥門及安全閥，應(yīng)設(shè)平臺(tái);對(duì)不經(jīng)常操作的閥門也應(yīng)采取適當(dāng)?shù)拇胧ㄈ珂溳?、延伸桿、活動(dòng)平臺(tái)或活動(dòng)梯子等）。鏈輪的鏈條不應(yīng)妨礙通行。內(nèi)有危險(xiǎn)介質(zhì)的管道和設(shè)備上的閥門，不得安裝在人的頭部高度范圍內(nèi)，以免傷人。（2）水平管道上的閥門的閥桿比較好垂直向上或向左或右偏45.水平安裝也可，但不準(zhǔn)向下。垂直管道上的閥門桿朝向操作面，但應(yīng)注意不要影響通行。（3）對(duì)于質(zhì)量較大的閥門，應(yīng)在附近設(shè)立支架，閥門法蘭與支架間距應(yīng)大于300mm;對(duì)于大型閥門，應(yīng)考慮吊裝的條件。（4）平行布置管道上的閥門，其中心線盡量對(duì)齊。手輪間的凈距不應(yīng)小于100mm。閥門應(yīng)盡量靠近干管和設(shè)備安裝。與設(shè)備管嘴相連接的閥門，若公稱壓力、直徑、密封面形式與設(shè)備管嘴法蘭相同或?qū)?yīng)時(shí)，可直接連接。從干管引出的支管，一般要在靠近根部且在水平管段上設(shè)切斷閥。（5）升降式止回閥應(yīng)裝在水平管段上;立式升降式止回閥可裝在垂直管道上;旋啟式止回閥應(yīng)優(yōu)先裝在水平管道上。</p><p> 氣動(dòng)閥門的日常注意事項(xiàng)： </p> <p> 1、填料函更換。填料函更換時(shí)應(yīng)采用同類型的填料函，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)按照說明書要求，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?？赏ㄟ^調(diào)節(jié)鋼珠的壓緊力調(diào)整放大器增益，防止共振。由于流體的流動(dòng)速度快，在流經(jīng)閘閥的過程中溫度下降的趨勢(shì)很小。</p><div
