(法兰,内螺纹)进口气动高压球阀旋转控制芯轴使球体从开启位置切换到关闭位置,系统压力将球体推向密封碗的无压制侧并无泄漏地切断液流  RETZ (Flange, internal thread) The inlet pneumatic high-pressure ball valve rotates the control spindle to switch the ball from the open position to the closed position, and the system pressure pushes the ball to the non pressing side of the sealing bowl to cut off the liquid flow without leakage

6、两端调的节螺钉可使标准产品在0°和90°有±4°的可调范围。确保与阀门的同步精度 The adjustable pitch screws at both ends can make the standard products have an adjustable range of ± 4 ° at 0 ° and 90 °. Ensure synchronization accuracy with the valve


特点Characteristic

全流量流通,启闭迅速,从全开到全关只要旋转90° Full flow circulation, quick opening and closing, and 90 ° rotation from full opening to full closing

流体阻力小,全通径的球阀基本没有流阻  The fluid resistance is small, and the full bore ball valve basically has no flow resistance

耐高压,启闭迅速,扭矩低,无泄漏,不需要手工重调密封件 High pressure resistance, quick opening and closing, low 

紧密可靠,密封面材料为PTFE,密封性好,能实现完全密封。在真空系统中也已广泛使用 Tight a
torque, no leakage, no need to manually readjust the sealsnd reliable, the sealing surface material is PTFE, with good sealing performance, and can achieve complete sealing. It has also been widely used in vacuum systems

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 the valve is fully opened or closed, the sealing surfaces of the ball and valve seat are isolated from the medium. When the medium passes through, it will not cause erosion of the valve sealing surface
