产品特点 Product features:

1、 优质材料、合理结构、精湛工艺,按ASME B16.34标准设计制造。专为苛刻工况设计制造,圆满解决介质高速冲刷、气泡内爆剥蚀而导致的内漏,使用寿命长。通过减少流体系统的泄漏和维护量,达到延长设备的安全运行所需的时间,降低运行成本,从而提高用户的经济效益。

The valve has high quality materials, reasonable structure and exquisite craft. The valve is especially designed and manufactured for harsh working conditions, it can solve the internal leakage caused by the high speed scouring of the medium and implosion and denudation of the bubble. The valve has very long working life. The standard is ASME B16.34


2、 阀杆螺母:与阀杆配合启闭阀门,与轴承配合,实现阀杆升降不旋转

Stem nut: to open and close the valve together with the stem, help the stem to move up and down directly together with the bearing.

3、 锻造支架:密度大、强度高

Forged support: large density and high strength

4、 阀杆:精磨后经防腐处理

Stem: treated with preservatives after fine grinding

5、 阀座:Stellite硬质合金,耐磨抗冲刷,与锥瓣配合,密封性好

Seat: Stellite hard alloy, good wear resistance, anti-erosion resistance and good sealing performance with the cone petal

6、 阀瓣:Stellite硬质合金,耐磨抗冲刷性好

Seat: Stellite hard alloy, good wear resistance and anti-erosion resistance

7、 阀体:密度大、承压高

Body: large density and high pressure capability
