柱塞阀结构.doc

柱塞阀结构跨国公司在华“造污”不容忽视据报道，2004年以来，有33家在华知名跨国公司因违法违规排污被各地环保部门曝光，其中包括5家2006年“世界500强”企业。经查实，这些跨国企业存在的主要环境问题是“超标排放污染物废水”。令人担忧的是，被曝光的少数跨国企业已成为当地的污染大户。当初，这些跨国公司进军中国市场时，都标榜自己是全球“最干净、最清洁”的企业，执行的是世界上最严格、最科学的“环保标准”。可时间不长却“蜕变”成了“排污企业”，甚至是“污染大户”，严重污染了中国环境。原因何在？笔者分析，首先是跨国公司缺乏应有的企业责任和社会责任。这些企业在国内或许做得很好，可到了他国却将环保抛在一边，甚至肆无忌惮地排污，这是社会责任的严重缺失。在全球经济一体化的今天，作为一个有责任感的跨国公司，无论在哪个国家办厂都应该牢记和恪守自己的环境责任及义务。其次是我国的环保监察和执法力度薄弱，有的地方对外企违法排污行为网开一面，“睁一只眼、闭一只眼”，不敢依法监管和处罚，害怕管严了“吓跑”了外商。再就是少数跨国企业在产业结构调整中，故意将污染项目和产品转移到中国市场，而我国的环境准入门槛较低，环境标准普遍低于一、产品截止阀的详细资料：产品名称：金属密封柱塞阀柱塞截止阀UJ41H-16C性能规范：公称压力（PN）：1.6Mpa低压气密封试验压力：0.6Mpa强度试验压力（PT）：2.4Mpa适用介质：蒸汽、油品、水UJ41H（Y）-25性能规范：公称压力（PN）：2.5-4Mpa低压气密封试验压力：0.6Mpa强度试验压力（PT）：3.75-6Mpa适用介质：蒸汽、油品、水二、工洲牌金属密封柱塞阀主要连接、结构尺寸：DN(mm)尺寸（mm）UJ41H-16C、Y、P、R1520253240506580100125150200250300350400L130150160180200230290310350400480495622698787914H1701902102502703003403804204505406407408509701100W100100120140160180200240270310340400520640760900D95105115135145160180195215245280335405460520580K657585100110125145160180210240295355410470525D14555657885100120135155185210265320375435485t14141416161618202022242630303436n-4-144-144-184-184-184-184-188-188-188-188-2312-2312-2512-2516-2516-30重量（千克）3545558115152130425590142210290500-DN(mm)尺寸（mm）UJ41H（Y）-25C、P、R1520253240506580100125150200250300350400L130150160180200230290310350400480495622698787914H1701902002302602803003704004205105907108309501080W100100120140160180200240270310340400520540780900D95105115135145160180195230270200375445510570655K657585100110125145160190220250320385450510585D1395057657587109120148175203259312363421473t16161618182022222422303842465258n-4-144-144-184-184-184-184-188-188-238-258-2512-3012-3416-3416-3416-41DN(mm)尺寸（mm）UJ41H-40C、Y、P、R1520253240506580100125150200250300350400L130150160180200230290310350400480533622711838914H1701902102502703003403804204605406407408509801100W100100120140160180200240280310340400520640760900D95105115135145160180195230270300360425485550610K657585100110125145160190220250310370430490550D14555657885100120135160188218278332390448505t16161618182022222428303436404448n-4-144-144-144-184-184-188-188-188-238-258-2512-2512-3016-3016-3416-34重量（千克）3.54.55.5811.515213042.55791150220300550-一、产品密封柱塞阀的详细资料：产品名称：非金属密封柱塞阀产品特点：这类阀门适用于治金、电业、化工、炼油、化肥、纺织、轻工、食品等行业中，压力为16-25kgf/cm2以内，温度为250以下的水、蒸汽、油类等管道上作为介质流动的启闭装置，也可以作为调节流量之用。二、工洲牌UJ41SM柱塞截止阀主要连接、结构尺寸：DN(mm)尺寸（mm）UJ41SM-16C、P、R1520253240506580100125150200250300350400L130150160180200230290310350400480495622698787914H1701902002302602803003704004205105907108309501080W100100120140160180200240270310340400520640760900D95105115135145160180195215245280335405460520580K657585100110125145160180210240295355410470525D14555657885100120135155185210265320375435485t14141416161618202022242630303436n-4-144-144-184-184-184-184-188-188-188-188-2312-2312-2512-2516-2516-30重量（千克）3545558115152130425590142210290500-DN(mm)尺寸（mm）UJ41SM-25C、P、R1520253240506580100125150200250300350400L130150160180200230290310350400480533622711838914H1701902102402402703003504004405105907108309501080W100100110140160180200240270310330400520640760900D95105115135145160180195230270300360425485550610K657585100110125145160190220250310370430490550D14555657885100120135160188218278332390448505t16161618182022222428303436404448n-4-144-144-144-184-184-188-188-188-238-258-2512-2512-3016-3016-3416-34重量（千克）35455581151521304255791150220300550-DN(mm)尺寸（mm）UJ41SM-40C、P、R1520253240506580100125150200250300350400L130150160180200230290310350400480495622698787914H1701902002302602803003704004205105907108309501080W100100120140160180200240270310340400520540780900D95105115135145160180195230270300375445510570655K657585100110125145160190220250320385450510585D1395057657587109120149175203259312363421473t16161618182022222428303842465258n-4-144-144-144-184-184-184-188-188-238-258-2512-3012-3416-3416-3416-41一、产品柱塞阀的详细资料：产品名称：内螺纹连接柱塞阀产品特点：工洲牌内螺纹连接分非金属密封，金属密封两类，此外，外螺纹连接柱塞阀其外形分为Z字形和腰鼓形两大类，其内部结构完全相同，用途一样，主要用在冶金、电业、化工、炼油、食品等行业。压力为16-25kgf/cm2以内，温度为250以下的水、蒸汽、油类等小口径管道上作开启、关闭调节流量用。二、工洲牌内螺纹柱塞阀主要连接、结构尺寸：DN(mm)尺寸（mm）UJ11-UJ11SM-15、25、40C、P、R152025324050L90100120140170200H120140165175195213H1148175205215246268W80100120140160180G1/23/4”1”11/4”11/2”2”L1141618202224S323646556580重量（千克）152.53.55.58.512一、产品柱塞式闸阀的详细资料：产品名称：金属密封柱塞式闸阀二、工洲牌柱塞式闸阀主要连接、结构尺寸：DN(mm)尺寸（mm）UZ41H-16C（Y、P、R）1520253240506580100125150200250300350400L130150160180240250265280300325350400450500550600W100100120140160180200240270310340400520640760900D95105115135145160180195215245280335405460520580K657585100110125145160180210240295355410470525D14555657885100120135155185210265320375435485t14141416161618202022242630303436n-4-144-144-144-184-184-184-188-188-188-188-238-2312-2312-2516-2516-30DN(mm)尺寸（mm）UZ41H-25C（Y、P、R）1520253240506580100125150200250300350400L130150160180240250265280300325350400450500550600W100100120140160180200240280310340400520640760900D95105115135145160180195230270300360425485550610K657585100110125145160190220250310370430490550D14555657885100120135160188218278332390448505t16161618182022222428303436404448n-4-144-144-144-184-184-188-188-188-

工洲牌柱塞式截止阀是由阀体、阀盖、阀杆、柱塞、密封圈、手轮等零七八碎件组成（如图）。当旋转手轮时，通过阀杆带动柱塞，使柱塞顶斜锥面与阀座锥面往复离合，完成阀门的开启和关闭。 在阀门中，柱塞与密封圈间采用过盈配合。通过调节阀盖固定螺栓的压紧，使密封圈被压缩，内圈紧包柱塞外圈紧贴阀腔内壁，这样在密封圈上所产生的径向分力将在于流体的压力，从而保证了密封性，杜绝了外泄漏。 由于密封圈采用回弹性强，而靡性高的无毒新型密封材料，所以密封可靠、经久耐用。阀座与柱塞的锥面密封部位，采用优质耐靡材料，能保证阀门的使用寿命。 本阀门结合柱塞阀的无泄漏优点和截止阀的启闭快特点，成为一个结构新颖、用途广泛的新品种。二、柱塞阀式截止阀的安装及维修： 1、本厂生产的柱塞式截止阀出厂前每只均经过调试，按标准试压，持续三分钟无渗漏使用时只需外表及孔腔清洗干净，不必拆洗和调整更动，基本上可保证在一年内无须检修。 2、本阀门可在管疲乏上任意位置安装。介质流动方向见阀体上箭头所示。 3、经过一段时间的使用如有渗漏必须先交无效分蘖门开启后，再将阀盖上的压紧螺栓均匀地略加旋紧压至不漏即可，不宜盲目将螺栓拧得太紧，造成密封圈压坏，失去密封作用。 4、当密封圈损坏需要更换时应注意防止柱塞和新密封圈表面划痕和碰伤。 三、应用规范：设计与制造柱塞阀、柱塞阀截止阀、GB12235，柱塞闸阀GB12234结构长度国标GB12221、部标JB97、美标ANSI、B16.10法兰结构尺寸JB81-59、HB5010-58、HG20592
