三通针型阀 截止阀

进口三通针型阀，截止阀性能参数  Performance parameter

三通针型阀亦称三通截止阀、三通仪表阀、三通压力表阀、三通分流针型阀、三通切换针型阀  RETZ  three-way needle valve is also called three-way stop valve, three-way instrument valve, three-way pressure gauge valve, three-way three-way diversion needle valve, three-way switch needle valve

结构特征:

锥面密封,活动阀瓣 Structural features: cone seal, movable valve disc

流通型式: 三通式，直通，角通，分流 Circulation type: three-way, straight, angle, split

功    能:根据阀芯的不同有切断和节流两种 Function: according to the different valve cores, there are two kinds of cutting and throttling

三通针型阀是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的retz品牌 The three-way needle valve changes the connection between the two main holes or between the main hole and the side hole by rotating the position of the valve stem

逆时针旋转阀杆以连接两个主孔并关闭旁通孔  Rotate the valve stem counterclockwise to connect the two main ports and close the bypass port

顺时针旋转阀杆和关闭两个主孔，其中一个主孔将连接到旁通孔 Turn the valve stem clockwise and close the two main holes, one of which will be connected to the bypass hole

如果旋转阀杆居中，也就不是顶部也不是底部，这个时候所有的三个孔都连接起来了 If the rotary valve rod is centered, it is neither the top nor the bottom. At this time, all three holes are connected
