进口法兰球阀德国（莱克）原装进口法兰球阀指的是用法兰连接的不锈钢球阀，靠旋转阀来使阀门畅通或闭塞。不锈钢球阀不易被介质冲蚀，在各行业得到广泛的应用。我们常见的球阀从材质上,可以分为:碳钢球阀,304不锈钢球阀,316球阀和铜球阀等，下面介绍其操作与使用：1)、操作前须确认管路和阀已被冲洗过；2)、阀的操作按执行机构输入信号大小带动阀杆旋转完成：正向旋转1/4圈(900)时，阀关断。反向旋转1/4圈(900)时，阀开启；3)、当执行机构方向指示箭头与管线平行时，阀门为开启状态;指示箭头与管线垂直时，阀门为关闭状态。不锈钢球阀广泛应用于石油、化工、发电、造纸等各部门，以及人们日常生活中。法兰不锈钢球阀使用步骤。译文：Stainlesssteelballvalvereferstothestainlesssteelballvalvewithflangeconnection,byrotatingthevalvetothevalvefloworocclusion.Stainlesssteelballvalveisnoteasytobemediumerosion,hasbeenwidelyusedinvariousindustries.Ourcommonballvalvefromthematerial,canbedividedinto:carbonsteelballvalve,stainlesssteelballvalve304,316ballvalvesandcopperballvalve,thefollowingintroducestheoperationanduseof:1),shallconfirm,pipingandvalvesh***ebeenwashedoffbeforeoperation;2),operationofthevalveactuatoraccordingtothesizeoftheinputsignaltodrivethevalverodtorotate:forwardrotation1/4ring(900),thevalveoff.Counterrotating1/4ring(900),valveopen;3),whentheactuatordirectionarrowparallelwiththepipeline,thevalveisopen;arrowandtheverticalpipe,thevalveisclosed.Stainlesssteelballvalveiswidelyusedinpetroleum,chemical,electricpower,papermakingandotherdepartments,aswellaspeople'sdailylife.)
