进口高温高压排污门针型截止阀结构特征 structure characteristics

设计符合ASME VIII，ANSI B16.34/B16.5B31.3 和API6D的相关要求retz品牌  The product design shall conform to ASME VIII, ANSI B16.34/B16.5B31.3 and API6D

不旋转阀芯，以确保压力关闭的紧密性不旋转阀杆承受超高压和超高温 Do not rotate the valve element to ensure the tightness of pressure closing. Do not rotate the valve stem to withstand ultra-high pressure and ultra-high temperature

垂直升降式而非旋转升降式阀杆设计，避免阀门密封副间相对旋转产生刮伤及减少密封填料的磨损，有效地提高了阀门及填料的使用寿命 The design of vertical lifting valve stem instead of rotary lifting valve stem can avoid scratches caused by relative rotation between valve sealing pairs and reduce the wear of sealing packing, effectively improving the service life of valve and packing

间歇式填料系统设计，有效地减少填料的冷流及阀门的操作力矩，同时可利用系统介质对填料的作用实现更好的密封 Intermittent packing system design can effectively reduce the cold flow of the packing and the operating torque of the valve. At the same time, the effect of the system medium on the packing can be used to achieve better sealing

填料采用安装在阀杆传动螺纹下方的方式设计，以实现传动螺纹润滑物质与系统介质的隔离，避免传动螺纹润滑物质对系统介质的污染  The packing is designed by installing under the transmission thread of the valve rod to isolate the transmission thread lubricant from the system medium and avoid the pollution of the transmission thread lubricant to the system medium

阀杆螺纹为滚压制减少磨损长手柄大大减少操作扭矩 The valve rod thread is rolled to reduce wear. The long handle greatly reduces the operating torque

阀杆和填料函接头和阀体是相扣设计，防止阀杆脱离 The joint between the valve stem and stuffing box and the valve body is designed to be interlocked to prevent the valve stem from separating
