style="font-size:16px;">球閥的類別：(1)浮動球閥。球體有一定浮動量，在介質(zhì)壓力下，可向出口端位移，并壓緊密封圈。這種球閥結(jié)構(gòu)簡單，密封性好。但由于球體浮動，將介質(zhì)壓力全部傳遞給密封圈，使密封圈負(fù)擔(dān)很重；考慮到密封圈承載能力的限制，又考慮到大型球閥如采用這種結(jié)構(gòu)形式，勢必操作費(fèi)力，所以只用于中、低壓小口徑閥門?；は到y(tǒng)的酸堿等腐蝕性介質(zhì)的裝置和管路系統(tǒng)中，宜選用奧氏體不銹鋼制造的、聚四氟乙烯為閥座密封圈的全不銹鋼球閥。冶金系統(tǒng)、電力系統(tǒng)、石化裝置、城市供熱系統(tǒng)中的高溫介質(zhì)的管路系統(tǒng)或裝置上，可選用金屬對金屬密封球閥。需要進(jìn)行流量調(diào)節(jié)時，可選用蝸輪蝸桿傳動的、氣動或電動的帶Ｖ形開口的調(diào)節(jié)球閥。(2)固定球閥。球體是固定的，不能移動。通常上、下支承處裝有滾動軸承或滑動軸</span><span
