                            4.阀门的操作机构4.1阀门操作时的启闭方向,一律应顺时针关闭。4.2由于管网中的阀门,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。4.3为了便于一个人的启闭操作,在管道工压状况下,大启闭力矩宜为240N-m。4.4阀门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。4.5阀门启闭程度的显示盘①阀门启闭程度的刻度线,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。4.6若阀门埋设较深,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。
                               5.阀门的性能检测5.1阀门某一规格批量制造时,应委托权威性机构进行以下性能的检测:①阀门在工压状况下的启闭力矩;②在工压状况下,能保证阀门关闭严密的连续启闭次数;③阀门在管道输水状况下的流阻系数的检测。5.2阀门在出厂前应进行以下的检测:①阀门在开启状况下,阀体应承受阀门工压值二倍的内压检测;②阀门的关闭状况下,两侧分别承受1.1倍阀门工压值,无渗漏;但金属密封的蝶阀,渗漏值亦不大于相关要求。
