进口蒸汽柱塞阀.doc

进口蒸汽柱塞阀生的是给环境带来的巨大压力，给人体健康和自然资源带来的严重危害。中国政府已经认识到了环境的退化问题，正在努力向更加均衡的发展模式迈进，提出了“科学发展观”和“和谐社会”的理念，并将理念付诸于行动。制定了国家经济和社会的发展规划，在其中突出了环境管理的内容；构建了完善的现代化的环境、制度、政策体系；加强了环境机构建设，将环境和自然资源管理置于优先发展的战略地位。上述努力使得中国在环境保护各领域，如大气环境质量、水资源管理和水污染控制、固体废弃物的处置与回收、自然保护等方面取得了令人瞩目的成绩。主要表现在：中国的大气环境质量得到了改善，“九五”期间制定的固定源的二氧化硫、烟尘和粉尘的排放目标达到并且超额完成，“十五”计划中提出的固定源烟尘排放（削减10%）和工业粉尘排放（削减20%）的目标基本实现；进一步深化了水环境领域的改革，水资源管理和水污染控制机制不断完善，尤其是运用经济手段管理水环境的作用得到加强；危险和医疗废物处理能力得到加强，达到并超过了“九五”和“十五”计划制定的回收、废弃原料再利用和垃圾填埋安全处置目标；一、结构及特点： 工洲牌不锈钢柱塞阀是由阀体、阀盖、阀杆、柱塞、孔架、密环、手轮等零件组成（如图）。当手轮旋转时，通过阀杆带动柱塞在孔架中间上下往复运动来完成阀门的开启与关闭功能。在阀门中柱塞与密封环间采用过盈配合，通过调节压盖中法兰螺栓，使密封环压缩所产品生的侧向力与阀体中孔面及柱塞外圆密封，从而保证了阀门的密封性，杜绝了内泄漏、同时阀门开启矩小、能实现阀门的迅速开启和关闭。由于密封环采用回弹性强、耐磨性高的无毒新型密封材料，具有经受长期高温、高压而不丧失弹性，所以密封性能可靠，经久耐用。二、安装和维修：工洲公司生产的柱塞阀出厂前均按ZBJ16006进行试验、验收、使用时只需将外表及孔腔清洗干净，不必拆洗和更换。本柱塞阀可在任意位置安装，介质流动方向见阀体一箭头所示。经过一段时间的使用密封环如有磨损及渗漏必须先将阀门关闭后，再将中法兰螺栓均匀地略加旋紧以至不渗漏即可同时更换时应防止柱塞和新装密封环裂痕和碰伤。在短时间内，冷热交替温差较大的管道中，柱塞阀不能使用。三、柱塞阀的阀体材料：铸钢铸铁不铁钢含钼不铁钢WCBHT200CF8（304）CF8M（316）四、柱塞阀的密封圈材料：上密封圈材料下密封圈材料四氟乙烯加柔性石墨（PTFE）四氟乙烯加柔性石墨（PTFE）五、不锈钢柱塞阀的主要结构尺寸:1.6MPa

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
