  (1)闸阀足球比分波胆类阀体的结构和工艺分析:阀体是中空、壁薄的壳体零件,多为三通管状,用于直线管路上。该阀体的进口通道与出口通道同轴,故称直通式(见下图)。两通道端部为圆形法兰,法兰上有均匀分布的螺栓孔,以便与管道上的法兰连接。阀体上端亦有中法兰,用以连接阀盖。

闸阀足球比分波胆阀体密封面不仅具有很高的角度精度的要求,为了保证闸板的正常配合位置,要求两密封面中心的距离(通称为开档宽度)的精度有很高的要求。对于中心线相对称的两个密封面与导向筋的对称度也有—定要求。

2)中、大口径的加工方案:先加工两端法兰,再以端法兰为精基准,依次加工中法兰、导向筋、密封面部位及法兰螺栓孔等。

   以上两密封面的角度加工主要由夹具来保证、为了达到此目的,通常在制造斜胎夹具时采用同—个角度母板。即用与阀体密封面角度完全相同的两块母板,其中一块用作制造加工阀体密封面夹具的母板。将两块母板重叠(等于两倍阀体密封面的斜角),即可作为制造加工闸板密封面夹具的母板。用这种方法制造的夹具加工,可以保证阀体密封面与闸板密封面的角度完全—致。为了保证两密封面的对称性和开裆宽度尺寸精度,需提高阀体全长的制造精度,以便控制半长尺寸,全开档尺寸用专用的开挡量具来控制。

   这种方案的优点是:工艺装备相对比较简单,有利于夹具的标准化和通用化。其缺点是:两密封面加工需要两次装夹完成,而两次装夹的定位基准不统—,因此必然产生定位误差。这种加工方案若没有相应的工艺措施,就很难加工出能满足互换装配要求的阀体,这种方案由于采用的是各自独立的单个夹具,适用于大、中口径阀体的加工,在阀门行业应用比较广泛。

(四)阀芯关闭件的加工

  阀芯关闭件是指在阀门中起关闭作用的运动零件,它用来切断、调节或改变介质的流向。不同的阀类其关闭件的结构、形状都有很大差异,常见的有闸阀的闸板、截止阀的阀瓣、球阀的球体、蝶阀的阀板和旋塞阀的锥塞等。所有的关闭件上都有要与阀体密封面相吻合的精度和光洁度都很高的密封面,其重要程度和加工难度比相同形状的其他机械零件难度较大。其中又以闸阀的楔式闸板的难度尤为复杂,球阀的球体加工比较典型。下边就闸板和球体的加工工艺做代表性的介绍。


(1)XIESHIZHABANDEJIAGONG

1)楔式闸板的结构特点:闸板是外缘带凸块的圆盘,两端面为对称于中心面的倾斜密封面(多为5°),在其上端凸出部位有与阀杆连接的T形槽或螺纹。为使闸板能在阀体中顺利地开启和关闭,在闸板外缘的两侧面上有导向槽或导向筋。

  振动研磨机适合研磨中、小型截止阀止回阀阀瓣的密封平面。该设备的结构简单,工作可靠,可一次同时研磨几十个阀瓣零件,故具有较高的生产效率。由于研磨盘振动频率高、振幅小,工件与研磨盘之间相对运动的方向在不断变化,因而不仅工件研磨后的几何形状精度及光沽度好,研磨盘的磨损也比较均匀。

试验通常是在常温下以公称压力PN的1.1倍进行的。有的阀门密封试验压力有特殊要求的,按技术要求执行。    
闸阀和球阀由于有两个密封副,故需进行双向密封试验。试验时,先将阀门开启,把法兰一端封堵,压力从另一端引入,待压力升高到规定数值时将阀门关闭,然后将封堵端的压力逐渐卸去,并进行检查。另一端也应重复上述试验(见上图)。闸阀的另一种试验方法是在体腔内保持试验压力,从通路两端同时检查阀门的双向密封性。不过有些国外标准不允许这种试法,因为当铸造闸板芯部有穿透性缺陷时,这种试验可能会难以发现。
 截止阀试验时,阀瓣关闭后从入口端引入介质并施加试验压力,在出口端进行检查(见右图)。不过也有高压截止阀是采取上进下出的设计,试验时也要从入口端引入介质并施加试验压力。
  试验止回阀时,压力应从出口端引入,在入口端进行检查。  
密封试验时,手动阀门的关闭力按公称压力与公称通径决定。阀门通常只允许用正常体力关闭,而不得借助于其他辅助器械,过去老标准(JB790-65)规定当手轮直径φ≥φ320毫米时允许用两人关闭。而有些标准规定手动阀门的关闭力不能大于360N。
有驱动装置的阀门,应在使用驱动装置的情况下进行试验,当附带有手动装置时,还应在手动情况下试验其密封性。
阀门的密封试验应在总装后进行,因为试验不仅要检验阀门关闭件的密封性能,还要检验填料及法兰垫片的密封性能。
另外在阀门密封试验合格后,要进行带压开启的动作试验,以考验阀门启闭件在工况带压情况下的开启性能。
 (3)低温密封试验:
   随着现代技术的发展,液氧、液氮、液氢以及液化天然气等得到广泛的应用,从而对低温阀门的需求也愈来愈大。
低温阀门在常温强度试验和密封性试验合格后,再在低温状态下进行密封试验,以检验阀门在低温工况时的密封性能。
低温阀门的密封试验在日本阀门行业常用的有两种方法:浸渍法和保冷法。我国标准JB/T7749《低温阀门技术条件》里推荐的试验方法就是浸渍法,所以这里重点介绍这种方法。
浸渍法:阀门进行低温密封试验的方法和装置如右图所示。试验温度为-196℃,冷却剂为液氮,试验介质用氮气或氦气。
具体的试验操作在相应的技术规范里都有明确的规定。
在规定的压力持续时间内,渗漏量不大于允许数值,即可认为该阀门合格。
   试验温度是采用温度传感器来测定的。传感器贴在4~6个测温点上。阀门内腔各测温点的导线由阀门的填料处引出。
低温试验冷却介质可参照下表选用:

试验温度 ℃

-46

-101

-120

-160

-196

冷却介质

酒精+干冰

乙醚+液氮

酒精+液氮

乙戊烷+液氮

液氮

(4)真空密封试验:
   真空密封试验,是一种灵敏度很高的密封试验方法。航天及核工业用阀及密封性要求极高的阀门一般均进行真空密封试验。真空试验通常在阀门常温强度、密封试验合格后进行。为了保证试验的准确性,被试阀门应具有很高的清洁度和加工精细的密封面。

试验时,先把被测阀门在开启状态下抽至规定的真空度,再关闭被测阀门并使真空泵停泵放气,开始检测,直至测出在规定时间内的增压△P为止,然后计算阀门的漏气数率。                  
下图为真空密封试验的系统图:   

众所周知,所有金属材料在真空中都有放气现象。试验中测得的漏气率是气体渗漏和材料放气两种因素的结果。因此,静态升压法的灵敏度往往受材料放气率和计算准确性的影响。
更精确的真空密封性试验方法是氦质谱检漏。其方法是:将被测阀门用真空泵抽至规定的真空度后,在阀门被测部分外施加含氦的混合气体(氦罩或用氦气喷吹),如有漏隙,氮气便进入阀门的被测部分,系统中的氮质谱检漏仪就可显示出来,据此计算漏气数率。
真空阀门漏率的测试和计算可见JB/T6446《真空阀门》标准,该标准适用于高真空度要求的阀门。而火电厂汽轮机抽汽系统的真空度一般要求不高,其阀门的真空试验规定在要求的真空度下保压若干小时内,以表不升压为准。
(三 )阀门的试验设备:
阀门试验时使用的压力源,主要是由高压和中压泵以及气体压缩机供给的,这些设备可以满足常温时强度和密封试验的需要。高温蒸汽试验时,则用试验锅炉来供给具有一定压力和温度要求的高温蒸汽。
改革开放以来,随着阀门工业的发展和技术水平的提高,阀门行业的试验装备也有了很大的发展。各种机械、液压、机电一体化的试验设备不断得到推广应用,夹压式、翻转式、浸水式、内压平衡式的试验设备不断出现,使得阀门的试压工序从过去装卸盲板、紧固螺栓等繁杂的体力劳动转化为简单的机械操作,检漏的方法和精度也得到了明显的提高。
  
    
第十章 阀门制造工艺的发展方向
  
经过阀门行业几十年的努力,我国阀门制造工艺水平已经有了很大的提高。铸造生产从原始状态的一个人、一把铁锨、一堆土(砂),发展到现在多种铸造工艺、造型材料以及推广、应用树脂砂无箱造型自动生产线。机加工生产也从一个人、一把刀、一个活(工件)发展到推广、应用组合机床、加工流水线、数控机床和加工中心。
在毛坯制造方面,精密铸造和模锻的应用日益广泛,铸造和锻造的机械化水平也有大幅度的提高。不少工厂已采用造型、制芯、落砂、清理机械化。我国一些阀门厂利用精铸、模锻、冲压、滚压和镦头的方法来制造阀体、阀盖、阀杆等零件,大大减少了材料消耗和机械加工工时,取得了良好的效果。扩大无切屑和少切屑加工工艺的应用范围,减少金属切削量,是阀门制造工艺的一个发展趋向。
    密封面的堆焊普遍采用埋弧自动焊、氩弧焊、等离子喷焊等新工艺,推广和应用新型的焊接材料,既提高了生产效率,又保证了焊接质量。
    我国组合机床、自动生产线在计划经济时期应用较为普遍,适应于当时产品分工和专业化集中生产的计划经济模式。但由于专用组合机床和自动线的可调整、可变性、机动性较差,仅局限于加工几个规格批量大的产品,加上工装、刀具的调整时间较长的缺陷,使得设备的利用率不高。国外对批量较小、要求较高的阀门加工,也从专用组合机床逐步发展到使用多品种、可调变的数控机床和加工中心上来。在数控机床和加工中心上使用机械装夹不重磨的硬质合金刀具,硬质合金刀片上还涂敷碳化钛或氮化钛,刀具的寿命提高三倍以上。
   目前大多数阀门厂的生产模式都属于多品种、单件、小批轮番生产。在这种情况下使用专用组合机床、自动生产线等高效专机设备可能是不适宜的。采用数控机床或由普通机床增加数显装置的经济数控机床加工阀门,是提高生产效率和保证加工质量,适应多品种、小批量生产方式的灵活模式。
    为了减少辅助时间,我国阀门工业已部分使用电动、气动和液动的快速夹具。以气液增压机构为动力源的液动夹具,由于结构简单、休积小、成本低而适于推广应用。此外,通用调整夹具、标准夹具及组合夹具等也被广泛采用。
   阀门装配长期以来都是由人工用简单的工具来完成的,是最不易实现机械化和自动化的工序。我国近几年在发展阀门试验台架、清洗机械、装配机械等方面已作了大量工作,减轻了工人的劳动强度,提高了装配质量和效率。国外阀门制造业装配台架、装配生产线、装配自动线的应用较为广泛,机械手和机器人亦有所采用。
涂漆工序是影响阀门外观质量和防锈性能的重要环节。我国不少阀门厂已建立了红外喷漆、静电喷粉(塑)自动线,是阀门涂漆工序的一个新发展。
总之,我国在阀门铸造、锻造、焊接、热处理和机加工方面,虽然取得了长足的进步,但是由于市场竞争、利益驱动、只求眼前利益和短期行为的影响,使我们与国外先进水平仍存在一定的差距。尤其是在装配手段、试验条件、无损检测和基础理论研究方面的差距较大。国际上知名的阀门公司拥有自己的高温高压、低温深冷、真空、寿命、流阻、耐火等试验设备和齐全的无损检测手段。这些方面的改进还有待我国阀门行业的同仁们继续努力,共同提高。
