产品详情 Product details

三通针型阀采用优质锻钢加工，适用一进两出切换管控，,也可以将其中一个出口连接仪表,来作为仪表阀使用。阀尖垂直运动，无旋转使用寿命长，通过旋转阀杆的位置来改变两个主孔或主孔和旁边孔之间的连通The three-way needle valve is made of high-quality forged steel and is suitable for one in two out switching control. One of the outlets can also be connected to the instrument for use as an instrument valve. The valve tip moves vertically without rotation and has a long service life. By rotating the position of the valve stem, the connection between the two main holes or between the main hole and the adjacent hole can be changed

进口三通针型阀设计标准 Design standards

非旋转阀杆Without rotating the valve stem

锥形阀芯或球形阀芯

阀尖垂直运动，无旋转，使用寿命长

动载何密封设计，填料螺母可外部调整。

阀体采用整体式(精铸和锻压形阀体结构)。

两件式填料设计，减少了阀杆填料的磨损，填料可通过上部的碟簧自行补偿减少手轮的操作扭矩

上阀杆螺纹经滚压硬化处理，下阀杆表面经特殊硬化上阀杆螺纹的润滑脂与系统介质隔离
