- 商品名称: D381X-16Q沟槽涡轮信号蝶阀
- 商品编号: 1100456446320594944
若弹性座封闸阀埋设较深,操作机构及显示盘离地面距离≥1.5m时,应设有加长杆设施,且固定稳牢,以便人们从地面上观察及操作。也就是说,管网中的阀门启闭操作,不宜下井作业。
3.1弹性座封闸阀操作时的启闭方向,一律应顺时针关闭。
3.2由于管网中的气动阀,经常是人工启闭,启闭转数不宜过多,就是大口径阀门亦应在200-600转内。
3.3为了便于一个人的启闭操作,在管道工压状况下,最大启闭力矩宜为240N-m。
3.4暗杆闸阀启闭操作端应为方榫,且尺寸标准化,并面向地面,以便人们从地面上可直接操作。带轮盘的阀门不适用于地下管网。
3.5暗杆闸阀启闭程度的显示盘
①暗杆闸阀启闭程度的刻度线,应铸造在变速箱盖上或转换方向后的显示盘的外壳上,一律面向地面,刻度线刷上荧光粉,以示醒目;
②指示盘针的材质在管理较好的情况下可用不锈钢板,否则为刷漆的钢板,切勿使用铝皮制作;
③指示盘针醒目,固定牢靠,一旦启闭调节准确后,应以铆钉锁定。
3.6若弹性座封闸阀埋设较深,操作机构及显示盘离地面距离≥1.5m时,应设有加长杆设施,且固定稳牢,以便人们从地面上观察及操作。也就是说,管网中的阀门启闭操作,不宜下井作业。
