卫生级活结快装视镜 sight glass

用途：视镜可用于温度高，腐蚀性强、易中毒、危险性较大，易结晶的化工塔器中，以保证其安全生产。

1清洁处理。

在使用前可以用适量酒精棉在其表面轻微擦拭，注意：不要用含有酸性   的液体进行清洁，以免腐蚀玻璃外表面。

2要正确选择垫片。

环境工作温度在280度以内的场合，用石棉垫或四氟垫即可，当环境工作温度超出500℃时，建议选择石墨垫片。注意：玻璃越厚，所以选择的垫片厚度也要跟着相应增加。

3用力均匀。

安装时不可用力过猛、过大，建议均匀用力按对角线方式锁紧螺丝。

4定期检查。

视镜玻璃在安装完毕后，还必须做好定期检查工作，特别是在含有酸、碱的液体环境中，更是要做好定期检查玻璃表面受腐蚀程度，以确保一线操作人员的安全。

Sight glass

Uses: Mirrors can be used in high temperature, corrosive, easily poisoned, dangerous, easy to crystallize chemical tower in order to ensure its safe production.

1 cleaning process.

Before use, it can be slightly wiped with alcohol cotton on its surface. Caution: Do not use acidic liquid to clean the outer surface of the glass.

2 Select the gasket correctly.

Ambient temperature of 280 degrees or less occasions, asbestos or PTFE pad can be, when the ambient temperature exceeds 500 ℃, the proposed choice of graphite gaskets. Note: The thicker the glass, the thickness of the gasket should be chosen accordingly.

3 force evenly.

Installation can not force too much, too large, it is recommended that the uniform force diagonal locking screw.

4 regular inspection.

Mirror glass after installation is completed, but also must be regularly checked, especially in the liquid environment containing acid and alkali, but also to do a regular inspection of the surface of the glass by the corrosion level to ensure the safety of front-line operators.
