构造特点 Structural characteristics

阀体和阀盖中使用的特殊材料垫片适用于临界电站  Special material gaskets used in the valve body and bonnet are suitable for critical power plants

填料聚四氟乙烯（232℃）柔性石墨填料（648℃）Packing PTFE (232 ℃) Flexible graphite packing (648 ℃)

产品的设计符合ASME VIII，ANSI B16.34/B16.5B31.3 和API6D的相关要求  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

填料位于阀杆的下方，以隔绝螺纹与介质的接触  The packing is located below the valve stem to isolate the contact between the thread and the 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，防止阀杆脱离阀门100%氮气静压测试 The joint between the valve rod and stuffing box and the valve body are designed to be interlocked to prevent the valve rod from leaving the valve for 100% nitrogen static pressure test

非旋转阀杆  Without rotating the valve stem
