電動球閥種類有：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、鍛鋼球閥、卸灰球閥、抗硫球閥、三通球閥、氣動球閥、電動球閥、卡套球閥、焊接球閥、法蘭球閥，絲口球閥。浮動球：球閥的球體是浮動的，在介質(zhì)壓力作用下，球體能產(chǎn)生一定的位移并緊壓在出口端的密封面上，保證出口端密封。浮動球球閥的結(jié)構(gòu)簡單，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，河北**電動球閥哪家好，球體可能會發(fā)生偏移。這種結(jié)構(gòu)，一般用于中低壓球閥，河北**電動球閥哪家好。固定球：球閥的球體是固定的，受壓后不產(chǎn)生移動。固定球球閥都帶有浮動閥座，受介質(zhì)壓力后，閥座產(chǎn)生移動，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，河北**電動球閥哪家好，適用于高壓和大口徑的閥門。為了減少球閥的操作扭矩和增加密封的可靠程度，潤滑油，以形成一層油膜，即增強了密封性，又減少了操作扭矩，更適用高壓大口徑的球閥。

范圍：空氣、蒸汽、水、氣體、石油和石化產(chǎn)品、腐蝕性介質(zhì)。電動球閥;上海迦百農(nóng)閥門，V型電動球閥是一種芯閥座采用金屬，或金屬對聚四氟乙烯密封配合的旋轉(zhuǎn)球閥，電動球閥將球閥和蝶閥的比較好控制特性結(jié)合成一體,既可用作控制調(diào)節(jié)閥，又可作關(guān)斷切斷閥。其主要特點是: (1)不帶任何管接頭的整體式閥體，因此不受管道或螺栓應(yīng)力影響，并且由于閥體無任何管接頭，故耐壓殼體不會受壓力"突變"的影響; (2)電動球閥具有一個V型閥體，即使在小流量或高粘度介質(zhì)的情況下，也可在整個量程范圍內(nèi)，保證控制的精確性; (3)電動球閥防漏耐用的閥座在其外徑處襯有帶不銹鋼內(nèi)芯PTFE杯形或是O型密封圈，閥座用截面較大的鎢鈷硬質(zhì)合金制成，通過一個合金的波紋彈簧進一步增強了閥座的結(jié)構(gòu); (4)當(dāng)電動球閥閥門關(guān)閉時，V型缺口與電動球閥閥座之間產(chǎn)生楔形剪切作用，并既具有自潔功能又可防止球芯卡死，電動球閥特別適用于管線結(jié)垢凍結(jié)或含有纖維和顆粒固體場合。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> body> </p> <p> le> </p> <p> <br
