調(diào)節(jié)閥的安裝，必須確保安全性，確保使用性能，易于操作和維護，節(jié)約安裝費用。下面就針對這四點談一談安裝時需要注意的具體問題。1)防止泄漏安裝過程不允許調(diào)節(jié)閥產(chǎn)生泄漏。在使用過程中，如果在填料涵、法蘭墊片等部位形成縫隙或微孔就可能產(chǎn)生泄漏。如果流體介質(zhì)的操作條件苛刻，T型過濾器比如高溫、高壓、流體有腐蝕性，那么損壞將加劇，泄漏的危險性就更大。防止泄漏的方法很多，在安裝過程中，填料的選擇、密封方法的選擇、選用密封性能好的調(diào)節(jié)閥等，都是必須考慮的因素。2)安裝放泄閥任何一個管路設(shè)計和安裝，在切斷時都不可避免地積有高壓流體，如果積聚流體的潛在能量很大，應(yīng)在調(diào)節(jié)閥的兩側(cè)安裝放泄閥，這樣，在系統(tǒng)切斷之后，調(diào)節(jié)閥中殘留的高壓流體的能量能得到釋放，保護人員安全，有利于調(diào)節(jié)閥的維修，也可以考慮選用能限制流量的放泄閥。3)安全的管線在安裝調(diào)節(jié)閥前，全部安裝管件和管線都要吹掃干凈，因為管線中的砂粒、水垢、鐵屑等會損壞調(diào)節(jié)閥內(nèi)表面，尤其是要求嚴(yán)格的密封面。當(dāng)系統(tǒng)壓力波動嚴(yán)重時，建議在管線上安裝緩沖設(shè)施。如果被排放的流體是有害氣體或液體，那么排放流體用的管線必須連接到安全地點，也可以連接到安全的特定容器中。上海閥芯三通閥英格索蘭

熱流出口的高溫氣流直接作用在閥芯上，閥芯在約1400℃高溫、酸性介質(zhì)腐蝕及高溫氣流沖刷的共同作用下，很快就被燒損甚至熔毀報廢，致使高溫?fù)胶祥y無法正常使用，這也成為裝置安全長周期運行的一個重大***。2、高溫?fù)胶祥y閥芯的改進(jìn)、方案Ⅰ/1Cr25Ni20Si2閥芯表面噴氧化鋯在原1Cr25Ni20Si2拋物線型閥芯(見圖2)表面噴一層氧化鋯。氧化鋯是一種很好的高溫耐磨陶瓷材料，具有強度高、硬度高和韌性佳，空氣中穩(wěn)定使用**高溫度可達(dá)1800℃。我們曾在中石化荊門分公司硫磺回收裝置上進(jìn)行試驗，在高溫?fù)胶祥y投用約4個月后出現(xiàn)了氧化鋯剝落和閥芯被熔化的現(xiàn)象。通過分析其原因主要是：1Cr25Ni20Si2和氧化鋯之間的熱膨脹系數(shù)不一致，閥芯基體膨脹量大，可引起表面材料開裂，加之閥芯基體和表面材料之間結(jié)合不緊密而導(dǎo)致表面氧化鋯層剝落，氧化鋯層剝落的閥芯直接作用在高溫氣流之下，**終被熔毀。圖21Cr25Ni20Si2拋物線型閥芯、方案Ⅱ/1Cr25Ni20Si2加TA-218閥芯1Cr25Ni20Si2+(TA-218)閥芯目前使用**為***，閥芯基體采用1Cr25Ni20Si2材質(zhì)，閥芯表面襯有20mm厚TA-218耐磨襯里，該襯里和閥芯之間用掛片連接與固定。掛片為半圓環(huán)型或拋物線型，沖有舌形孔，數(shù)量為6～8件。</p><p>

1.閥前控制原理自力式閥前壓力控制（K），其初始閥芯的位置在關(guān)閉狀態(tài)。當(dāng)閥前壓力P1通過閥芯、閥座的節(jié)流后變?yōu)殚y后壓力P2，同時P1通過管線輸入上膜室作用在膜片上，其作用力與彈簧的反作用力相平衡時閥芯位置決定了閥的開度，從而控制閥前壓力。當(dāng)閥前壓力P1增加時，P1作用在膜片上的作用力也隨之增加。此時，膜片上的作用力大于設(shè)定彈簧的反作用力，使閥芯向離開閥座方向移動，導(dǎo)致閥的開度變大，流阻變小，P1向閥后泄壓，直到膜片上的作用力與彈簧反作用力相平衡為止，從而使P1降為設(shè)定值。同時，當(dāng)閥前壓力P1降低時動作方向與上述相反。這就是閥前壓力調(diào)節(jié)的工作原理。2.閥前控制原理自力式閥前壓力控制（B），其初始閥芯的位置在開啟狀態(tài)。當(dāng)閥前壓力P1通過閥芯、閥座的節(jié)流后變?yōu)殚y后壓力P2，同時P2通過管線輸入上膜室作用在膜片上，其作用力與彈簧的反作用力相平衡時閥芯位置決定了閥的開度，從而控制閥前壓力。當(dāng)閥前壓力P2增加時，P2作用在膜片上的作用力也隨之增加。此時，膜片上的作用力大于設(shè)定彈簧的反作用力，使閥芯向關(guān)向閥座的位置，導(dǎo)致閥的開度減小，流阻變大，P2降低，直到膜片上的作用力與彈簧反作用力相平衡為止。
