小金井節(jié)流閥的安裝注意事項(xiàng),koganei現(xiàn)貨
小金井節(jié)流閥(Choke valve)的外形結(jié)構(gòu)與截止閥并無(wú)區(qū)別,只是它們啟閉件的形狀有所不同。節(jié)流閥的啟閉件大多為圓錐流線型,通過(guò)它改變通道截面積而達(dá)到調(diào)節(jié)流量和壓力。節(jié)流閥供在壓力降*的情況下作降低介質(zhì)壓力之用。介質(zhì)在節(jié)流閥瓣和閥座之間流速很大,以致使這些零件表面很快損壞-即所謂氣蝕現(xiàn)象。為了盡量減少氣蝕影響,閥瓣采用耐氣蝕材料(合金鋼制造)并制成*角為140~180的流線型圓錐體,這還能使閥瓣能有較大的開(kāi)啟高度,一般不*在小縫隙下節(jié)流。
