style="text-indent:25px">球閥密封性好，但球體承受工作介質(zhì)的載荷全部傳給了出口密封圈，因此要考慮密封圈材料能否經(jīng)受得住球體介質(zhì)的工作載荷，在受到較高壓力沖擊時(shí)，球體可能會(huì)發(fā)生偏移。這種結(jié)構(gòu)，一般用于中低壓球閥。球閥的球體是固定的，受壓后不產(chǎn)生移動(dòng)。固定球球閥都帶有浮動(dòng)閥座，受介質(zhì)壓力后，閥座產(chǎn)生移動(dòng)，使密封圈緊壓在球體上，以保證密封。通常在與球體的上、下軸上裝有軸承，操作扭距小，適用于高壓和大口徑的閥門(mén)。為了減少球閥的操作扭矩和增加密封的可靠程度，又出現(xiàn)了油封球閥，既在密封面間壓注特制的潤(rùn)滑油，以形成一層油膜，即增強(qiáng)了密封性，又減少了操作扭矩，更適用高壓大口徑的球閥。你知道球閥行業(yè)優(yōu)勢(shì)有哪些嗎？浙江高壓三通球閥作用有哪些</p><p

style="text-indent:25px">適用場(chǎng)合：由于球閥通常用橡膠、尼龍和聚四氟乙烯作為閥座密封圈材料，因此它的使用溫度受到閥座密封圈材料的限制。球閥的截止作用是靠金屬球體在介質(zhì)的作用下，于塑料閥座之間相互壓緊來(lái)完成的（浮動(dòng)球球閥）。閥座密封圈在一定的接觸壓力作用下，局部地區(qū)發(fā)生彈塑變形。這一變形可以補(bǔ)償球體的制造精度和表面粗糙度，保證球閥的密封性能。又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(jié)構(gòu)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(mén)，在易燃、易爆介質(zhì)的設(shè)備和管路系統(tǒng)中使用球閥，更應(yīng)注意耐火和防火。江蘇高壓三通球閥生產(chǎn)公司</p><p
