衛(wèi)生級(jí)快裝視鏡 Sanitary clam sight glass
用途：視鏡可用于溫度高，腐蝕性強(qiáng)、易中毒、危險(xiǎn)性較大，易結(jié)晶的化工塔器中，以保證其安全生產(chǎn)。
1清潔處理。
在使用前可以用適量酒精棉在其表面輕微擦拭，注意：不要用含有酸性 的液體進(jìn)行清潔，以免腐蝕玻璃外表面。
2要正確選擇墊片。
環(huán)境工作溫度在280度以內(nèi)的場(chǎng)合，用石棉墊或四氟墊即可，當(dāng)環(huán)境工作溫度超出500℃時(shí)，建議選擇石墨墊片。注意：玻璃越厚，所以選擇的墊片厚度也要跟著相應(yīng)增加。
3用力均勻。
安裝時(shí)不可用力過猛、過大，建議均勻用力按對(duì)角線方式鎖緊螺絲。
4定期檢查。
視鏡玻璃在安裝完畢后，還必須做好定期檢查工作，特別是在含有酸、堿的液體環(huán)境中，更是要做好定期檢查玻璃表面受腐蝕程度，以確保一線操作人員的安全。
Sanitary clam 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.
