ASCO防爆電磁閥是把設(shè)備可能點(diǎn)燃爆炸性氣體混合物的部件全部封閉在一個外殼內(nèi),其外殼能夠承受通過外殼任何接合面或結(jié)構(gòu)間隙,滲透到外殼內(nèi)部的可燃性混合物在內(nèi)部爆炸而不損壞,并且不會引起外部由一種、多種氣體或蒸氣形成的爆炸性環(huán)境的點(diǎn)燃,把可能產(chǎn)生火花、電弧和危險溫度的零部件均放入隔爆外殼內(nèi),隔爆外殼使設(shè)備內(nèi)部空間與周圍的環(huán)境隔開。隔爆外殼存在間隙,因電氣設(shè)備呼吸作用和氣體滲透作用,使內(nèi)部可能存在爆炸性氣體混合物。
1、防爆電磁閥工作壽命長。
2、防爆電磁閥工作制式:分長期工作制,反復(fù)短時工作制和短時工作制三種。防爆電磁閥均為長期工作制,即線圈允許長期通電工作。對于長時間閥門開通只有短時關(guān)閉的情況,則宜選用常開電磁閥。用在短時工作制而批量又 很大時,可作特殊訂貨以降低功耗。
3、防爆電磁閥工作頻率:動作頻率要求高時,結(jié)構(gòu)應(yīng)優(yōu)選直動式電磁閥,電源聽優(yōu)選交流。
