加長(zhǎng)視鏡 Lengthen 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?xún)?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(guò)猛、過(guò)大,建議均勻用力按對(duì)角線方式鎖緊螺絲。

Lengthen 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.
