(仪表根部阀)进口管台式截止阀 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  The product design shall conform to ASME VIII, ANSI B16.34/B16.5B31.3 and API6D

非旋转阀杆：防止阀杆/阀座在阀门开启和关闭时产生磨损。Non-rotating Stem：To prevent the stem/seat when the valve opening and closing develop blemishes.

阀杆操作时绝对无泄漏 Absolutely no leakage during valve stem operation

金属对金属阀座密封：实现气密性关闭，在磨蚀性流体应用中延长阀杆/阀座寿命，能够承受反复开关操作，且抗腐蚀性极佳。Metal To Metal Seating：Implement tight closure, in abrasive.fluid applications extend the service life of the valve stem/seat, able to withstand repeated switch operation, and excellent corrosion resistance.

PTFE材质填料：确保阀杆与阀体间的密封。阀杆衬套和填料压盖材质可延长螺纹寿命，减小阀门操作扭矩。Ptfe Packing Material：Ensure that the valve stem and seal between the valve body. Stem bushing and lifting capping material can extend the life of the screw thread, reducing valve operating torque.

仪表阀采用不锈钢结构，延伸阀体获得隔热距离 The instrument valve is of stainless steel structure, extending the valve body to obtain insulation distance
