詳細(xì)介紹
力士樂電磁閥特點(diǎn):
1、力士樂電磁閥電磁閥和全不銹鋼;對于強(qiáng)腐蝕的介 質(zhì)必須選用隔離膜片式。中
性介質(zhì),也宜選用銅合金為閥殼材料的電磁閥,否則,閥殼中常有銹屑脫落,尤
其是動(dòng)作不頻繁的場合。氨用閥則不能采用銅材。
2、爆炸性環(huán)境:必須選用相應(yīng)防爆等級產(chǎn)品,露天安裝或粉塵多場合應(yīng)選用防
水,防塵品種。
3、電磁閥公稱壓力應(yīng)超過管內(nèi)zui高工作壓力。
力士樂電磁閥技術(shù)參數(shù):
1)根據(jù)介質(zhì)流向要求及管道連接方式選擇閥門通口及型號;
2)根據(jù)流量和閥門Kv值選定公稱通徑,也可選同管道內(nèi)徑;
3)工作壓差:zui低工作壓差在0.04Mpa以上是可選用間接先導(dǎo)式;zui低工作壓差
接近或小于零的必須選用直動(dòng)式或分步直接式。
