style="font-size:16px;">三通球閥有T型和L型。T型能使三條正交的管道相互聯(lián)通和切斷第三條通道，起分流、合流作用。L三通球閥型只能連接相互正交的兩條管道，不能同時保持第三條管道的相互連通，只起分配作用。成品油的輸送管線和貯存設備，選用法蘭連接的球閥。城市煤氣和天然氣的管路上，選用法蘭連接和內螺紋連接的浮動球球閥。冶金系統(tǒng)中的氧氣管路系統(tǒng)上，宜選用經(jīng)過嚴格脫五、低溫介質的管路系統(tǒng)和裝置上，宜選用加上閥蓋的低溫球閥。煉油裝置的催化裂化裝置的管路系統(tǒng)上，可選用升降桿式球閥。化工系統(tǒng)的酸堿等腐蝕性介質的裝置和管路系統(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。需要進行流量調節(jié)時，可選用蝸輪蝸桿傳動的、氣動或電動的帶V形開口的調節(jié)球閥。工作方式：L型流道的三通4面閥座球閥，采用2面閥座。主要用于流路的換向。T型流道的三通4面閥座球閥，采用4面閥座，受力平衡，保證閉止通道上可靠密封。主要用于分流、混流、換向以及三通道的完全開放。</span> </p><p> <span style="font-size:16px;">由于球閥的閥座密封圈通常采用塑料制成，故在選擇球閥的結構和性能上，要考慮球閥的耐火和防火，特別是在石油、化工、冶金等部門，在易燃、易爆介質的設備和管路系統(tǒng)中使用球閥，更應注意耐火和防火。球閥分有：浮動球球閥、固定球球閥、軌道球閥、V型球閥、三通球閥、不銹鋼球閥，浮動球球閥、鑄鋼球閥、鍛鋼球閥、卸灰球閥、抗硫球閥、卡套球閥、焊接球閥。球閥與旋塞閥的工作原理一樣，都是靠旋轉閥芯來使閥門打開或關閉。球閥的閥芯是一個帶孔的球，當該孔的中心軸線與閥門進出口的中心軸線重合時，閥門打開；當旋轉該球90°，使該孔的中心軸線與閥門進出口的中心軸線垂直時，閥門關閉。球閥的使用在工程上是常見的配件，所以在選擇球閥的時候也要選擇性價比好的球閥會更好。</span> 冶金系統(tǒng)中的氧氣管路系統(tǒng)中，宜選用經(jīng)過嚴格脫脂處理，法蘭連接的固定球球閥。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="高臺焊接球閥供應商家,焊接球閥"
