进口角式针型，仪表阀，截止阀结构特征 structure characteristics

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retz品牌 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 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
