GN743.7油位指示器油鏡觀液窗oil&sp;sight油標(biāo)視鏡觀察窗
&sp;
材料&sp;
銅&sp;
-&sp;A型：帶高科技聚合體（聚砜）反差屏。&sp;
-&sp;B型：無(wú)反差屏。&sp;
觀測(cè)窗&sp;
浮法玻璃。
O型密封環(huán)&sp;
R合成橡膠。&sp;
連續(xù)工作溫度&sp;
100°。
特征及應(yīng)用&sp;
由于GN743.7型油位指示器具有圓錐螺紋，因此可以進(jìn)行金屬密封。當(dāng)擰緊圓錐形陽(yáng)螺紋R時(shí)，適當(dāng)?shù)膱A柱形陰螺紋Rp會(huì)將其鎖緊。&sp;
在基準(zhǔn)面上，R-陽(yáng)螺紋的直徑與Rp-陰螺紋相同，因此可以手動(dòng)擰緊。使用工具擰緊可以增加嚙合強(qiáng)度并密封螺旋接頭。另外，通常采用密封膠（麻繩或特氟綸帶）進(jìn)行密封。R-螺紋“表面粗糙”，旋緊時(shí)密封膠不會(huì)移動(dòng)。GN743.7型油位指示器可以用于加壓油罐上。如有需要，可提供壓力和真空試壓數(shù)據(jù)。&sp;
