进口高温高压内螺纹截止阀

高温高压内螺纹截止阀在管线系统中用于关闭或开启的控制，保持系统正常运行。通过手轮驱动阀杆。阀杆以垂直的方向移动。当顺时针旋转手轮时，阀瓣落下来关闭管线，当逆时针旋转手轮时，阀瓣上升，开启管线 High temperature and high pressure internal threaded globe valves are used in pipeline systems to control closure or opening, maintaining normal system operation. Drive the valve stem through a handwheel. The valve stem moves in a vertical direction. When rotating the handwheel clockwise, the valve disc falls down and closes the pipeline. When rotating the handwheel counterclockwise, the valve disc rises and opens the pipeline

密封面不易磨损及擦伤，启闭时阀瓣与阀体密封面之间无相对滑动，因而磨损与擦伤均不严重，密封性能好。The sealing surface is not easy to wear and scratch, and there is no relative sliding between the valve disc and the valve body sealing surface during opening and closing, so the wear and scratch are not severe, and the sealing performance is good
