1·A good sealing surface, a good gloss.

密封性良好，表面光泽度良好。

2·Ideal for valve sealing surface of the ultra-precision machining.

最适用于阀门密封面的镜面滚压加工。

3·The inner surface at one end of metal insert is cone-shaped sealing surface.

上述金属嵌件一端部的内表面为锥形的密封面。

4·To ensure tight closure, and the valve seat valve sealing surface of the ground.

为了保证关闭严密，阀瓣与阀座密封面进行的研磨。

5·Imports of cut-off valve stem and valve seat sealing surface perpendicular to the axis.

进口截止阀的阀杆轴线与阀座密封面垂直。

6·The current nuclear valve sealing surface surfacing material is generally cobalt alloy.

目前核阀密封面堆焊材料一般均为含钴合金。

7·This provides a smooth corrosion free sealing surface and excellent abrasion resistance.

这提供了一个平稳抗腐蚀的密封面和良好的耐磨性。

8·The flange sealing surface should be smooth and clean, to seriously clean up oil and rust during installation.

法兰密封面应平整清洁，安装时要认真清理油污和锈斑。

9·Specially designed offset disc lifts quickly from sealing surface to minimize wear and reduce operating torque.

特殊设计的偏置阀瓣结构能够快速从密封表面提升起来，最大限度减小磨损并降低操作力矩。

10·The seal is designed so that the pressure of media acts on both ends to minimize the force on the sealing surface.

密封的设计是为了使媒介的压力影响的两端，以尽量减少力量在密封面。

密封面

1·The metal-plastic composite nut, according to Claim 1 and 2, is characterized in that the inner surface at one end of metal insert is cone-shaped sealing surface.

根据权利要求1或2所述的金属塑料复合螺帽，其特征在于所述金属嵌件一端部的内表面为锥形的密封面。

2·The inner surface at one end of metal insert is cone-shaped sealing surface.

上述金属嵌件一端部的内表面为锥形的密封面。

3·To ensure tight closure, and the valve seat valve sealing surface of the ground.

为了保证关闭严密，阀瓣与阀座密封面进行的研磨。

4·Most of the valve is sealed using force, that the valve is closed, forced to rely on external ram pressure to the valve seat to ensure the sealing surface of the seal.

大部分闸阀是采用强制密封的，即阀门关闭时，要依靠外力强行将闸板压向阀座，以保证密封面的密封性。

5·Low pressure seal test 4.4.1 for low pressure seal test, the sealing surface should be kept clean, no oil, no grease and seal fat, for to prevent scratches.

低压密封试验4.4.1进行低压密封试验时，低温阀门密封面应保持干净，无油、无油脂和密封脂，如需防止擦伤。
