(二片式,三片式)进口电动螺纹球阀依靠旋转阀芯来使阀门畅通或闭塞。阀座采用弹性密封结构，阀杆采用有倒密封的下装式结构，阀腔异常升压时，阀杆不会被冲击。retz The imported electric threaded ball valve (two piece, three piece) relies on a rotating valve to make the valve smooth or blocked. The valve seat adopts an elastic sealing structure, and the valve stem adopts a bottom mounted structure with an inverted seal. When the valve chamber is abnormally pressurized, the valve stem will not be impacted
进口电动焊接球阀设计特色 Design features
开闭迅速，从全开到全关只要旋转90°，便于远距离的控制Quick opening and closing, with only 90 ° rotation from full opening to full closing, facilitating remote control
在全开或全闭时，球体和阀座的密封面与介质隔离，介质通过时，不会引起阀门密封面的侵蚀When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface
旋转刻度盘顶部旋钮即可轻松完成电动执行机构与阀门连接后的电气、机械位置校准调试 Rotate the top knob of the dial to easily complete the electrical and mechanical position calibration and debugging of the electric actuator connected to the valve
