BQ941F电动保温球阀,夹套保温电动球阀
一、电动保温球阀 产品概述
良工公司生产的"良工"牌电动保温球阀是采用高精度电动执行机构与直通式夹套保温球阀组成,其具有良好的保温保冷特性,且电动保温球阀的通径与管径一致,同时又能有效降低管路中介质热量损失。电动执行器采用一体化结构,内置伺服系统,无须另配伺服放大器,可输入4-20mA控制信号或1-5VDC及220VAC电源即可控制运转。夹套保温电动球阀主要用于石油、化工、冶金、制药、食品等各类系统中,以输送常温下会凝固的高粘度介质。由于电动保温球阀采用整体式结构,因而夹套保温电动球阀比一般球阀体积更小,重量更轻,且无外漏,密封性能良好,夹套采用碳素钢管焊接比铸造的更加耐压牢固。
