GN743.7油位指示器油镜观液窗oil&sp;sight油标视镜观察窗
&sp;
材料&sp;
铜&sp;
-&sp;A型：带高科技聚合体（聚砜）反差屏。&sp;
-&sp;B型：无反差屏。&sp;
观测窗&sp;
浮法玻璃。
O型密封环&sp;
R合成橡胶。&sp;
连续工作温度&sp;
100°。
特征及应用&sp;
由于GN743.7型油位指示器具有圆锥螺纹，因此可以进行金属密封。当拧紧圆锥形阳螺纹R时，适当的圆柱形阴螺纹Rp会将其锁紧。&sp;
在基准面上，R-阳螺纹的直径与Rp-阴螺纹相同，因此可以手动拧紧。使用工具拧紧可以增加啮合强度并密封螺旋接头。另外，通常采用密封胶（麻绳或特氟纶带）进行密封。R-螺纹“表面粗糙”，旋紧时密封胶不会移动。GN743.7型油位指示器可以用于加压油罐上。如有需要，可提供压力和真空试压数据。&sp;
