這種變換閥在石油、化工生產(chǎn)中有著普遍的應(yīng)用，在合成氨造氣系統(tǒng)中**為常用。此外，換向閥還可作成閥瓣式的結(jié)構(gòu)，多用于較小流量的場合。工作時只需轉(zhuǎn)動手輪通過閥瓣來變換工作流體的流向。六通換向閥主要由閥體、密封組件、凸輪、閥桿、手柄和閥蓋等零部件組成（圖1）。閥門由手柄驅(qū)動，通過手柄帶動閥桿與凸輪旋轉(zhuǎn)，凸輪具有定位驅(qū)動與鎖定密封組件的開啟與關(guān)閉功能。手柄逆時針旋轉(zhuǎn)，兩組密封組件分別在凸輪的作用下關(guān)閉下端的兩個通道，上端的兩個通道分別與管道裝置的進(jìn)口相通。反之，上端的兩個通道關(guān)閉，下端兩個通道與管道裝置的進(jìn)口相通，實(shí)現(xiàn)了不停車換向。英格索蘭Ingersoll

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(yùn)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(qiáng)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。復(fù)盛
