Description

环境密封仪器环路适配器
发明领域
本发明涉及一种仪器，例如在工业流体处理装置中测量流体特性的变送器。本发明尤其涉及在存在污染的工业环境中使用于仪表回路的电路连结变送器。
背景技术
工业变送器用来监视如炼油厂、化学加工厂及类似生产过程的操作。工业变送器，例如压力变送器经常用于流体处理装置中，这种装置所处的环境可能会存在液体、灰尘和潮湿及各种工业污染物。在某些环境中，可能存在如酸性或碱性溶液这样的液体。所述液体也可包括来自软管用来清洗固定设备的喷雾。液体可滴到、溅到或喷到工业变送器上及其电连接件上。环境中的灰尘、湿气和液体可污染和侵蚀连接到工业变送器的电连接件。
工业变送器经常配有密封布线盒，连接到密封电导线上以防止环线和电路连接件被污染而损坏。然而，在使用接头型连接器的小型工业变送器的情况下，没有密封线盒来防止接头中裸露的触针受到污染。
有必要将保护性适配器连接到工业变送器接头的触针上，这样就可以防止触针和线路受到污染，而不必增加昂贵的费用和庞大的线盒。
发明内容
应用本发明，环境密封电路适配器可防止触针、接触孔和线路受到液体、湿气和其它污染。
适配器包括一端与接触孔相连的线路，该触孔与工业变送器接头内的触针相适配。适配器还包括一个可旋到接头上的套筒。该套筒有一个朝向圆柱型接头的凸缘。
环境密封弹性件和垫圈被压挤在圆柱型接头和凸缘之间。垫圈有一个垫圈面，当螺纹拧紧时它可以相对凸缘滑动。压挤弹性件，在弹性件和密封面之间就形成了防液体密封。
触针、触孔和线路端部被弹性件有效地环境密封，这样也就防止了环境污染的损坏。

具体实施方式
环境密封仪器电路适配器将工业变送器连接到多路仪表回路中。弹性部件形式的环境密封对位于螺纹外套筒上的凸缘和工业变送器上带有螺纹的接头之间的线路和配件进行密封。止推垫圈用来在凸缘和弹性件之间提供滑动，以便限制螺纹拧紧时弹性件的扭转。当螺纹拧紧时弹性件保持平坦以形成良好的密封防止环境污染。适配器可防止触针、触孔和环线由于液体滴到、溅到或喷到工业变送器上而受到损坏，以及灰尘、湿气和其它污染物的损坏。适配器用来提供任何形式的电路连接使其连接到变送器，如2线环路或数字数据连接。
图1是差动压力变送器100的横断面图。变送器100是工业变送器的一个例子，在其上环境密封适配器(没有在图1中示出)可用于形成到仪器环路的连接。
变送器100包括一个带有外壳104的微型变送器壳102，密封到电路连接器接头106上。变送器壳102包括两个共面的流体入口108，流体入口108包括隔膜110。在变送器100中，密封在管路中的隔离流体112将差动压力从入口108传送到电容差动压力变送器114上。
变送器100包括一个带有圆柱形外壳或接头106的密封的穿通电连接器116以及一个密封的带有电路连接件或触针120的绝缘穿通118。接头106具有外部螺纹107。两个或多个触针120携带环路数据接通变送器100。
线路板122可电路耦合到压力变送器114。线路板122处理来自压力变送器114的数据，并控制触针120上的环路电流以表示入口108上的差动压力。压力可以表示为4-20mA的模拟电流，或可以表示为任何一种已知的数字协议如HART、CAN、foundation Fieldbus、Profibus协议和其它在流体处理控制工业中已知的数字通讯协议。
外壳104优选沿环形焊缝124与接头106焊接在一起，形成一个位于壳102内部的密封腔126。在绝缘穿通118上有一毛细管128，用来在密封管128之前检测泄露，目的是在小型压力变送器100中形成完全密封的密封腔126。
如图1所示的变送器100是一微型的变送器，它不包括在现场与仪器线路相连接的密封线盒。触针120和绝缘穿通118被暴露在变送器100之外，在流体处理厂环境中，易于受到污染物的不良接触，如灰尘、湿气或滴到、溅到或喷到其上的液体。
图2是一个环境密封仪器线路适配器130的横断面图，环境密封仪器线路适配器130被密封到如图1所示变送器100的工业变送器的接头132上。适配器130包括与接头132内部的多个触针相匹配的多个电接触孔134。接头132还包括一毛细管137，用来在密封毛细管137前检查泄露。接头132在138处被焊到密封的工业变送器外壳上(图2中没有示出)。多个电接触孔134与多线路仪表回路142的相应的第一线端140相连接。圆型套筒144旋在接头132上。圆型套筒144有一个凸缘146，它将弹性套150的弹性圈152挤压在接头132的密封表面148上。弹性套150优选围绕环路142塑型。弹性套150包括在凸缘146和密封面148之间的弹性圈152。至少有一个垫圈154位于凸缘146和弹性圈152之间。垫圈154有一个光滑的垫圈面，它可以相对于凸缘146滑动，套筒144在螺纹156上旋紧，就会在弹性圈152和密封面148之间形成环境密封，这时就可以限制弹性圈152的扭转。均匀地压缩弹性圈152可对密封面148形成连续环状密封。
垫圈154可起到止推垫圈的作用。垫圈154均匀地传送挤压力给弹性圈152，但可旋转滑动，以便当套筒144旋进时基本上隔离了弹性圈152上的扭转力。在一个优选的配置中，在凸缘146和弹性圈152之间可使用多个具有光滑的可滑动表面的垫圈154。若需要，垫圈154可以是自调中心的垫圈。
适配器130还包括一个硬质绝缘支柱158，它决定电接触孔134的位置并起到支撑作用。在支柱158根部的第一个O形环160和在套筒144和接头132之间的第二个O形环162提供另外的防潮密封。在某些实施例中，垫圈154和/或O形环162不是独立部件而是与其它部件制造成一体。
图3示出了带有选择线路的环境密封适配器131的横断面图。例如，线路可以是一个RFI/EMI滤波器。适配器131与图2中的适配器130相同，并且类似或相同的部件用相同的参考号表示。在适配器131中，仪表回路142的第一线端140不直接连接电接触孔134，而是通过RFI/EMI滤波器164间接与触孔134相连。经过EMI/RFI滤波器164后，来自仪表回路142的信号通过导线141与电路触针134相连。EMI/RFI滤波器164可包括一个带有电路元件的线路板，它可提供射频干扰(RFI)过滤，也称做电磁干扰(EMI)过滤。这样的RFI/EMI滤波电路的例子在下面图4中有更详细的描述。在RFI/EMI滤波器164周围形成如图所示的弹性套151。在优选的配置中RFI/EMI滤波器164在弹性套151中注模。
图4是一个RFI/EMI滤波器170的电路示意图。滤波器170与仪表回路142相连。滤波器170还与适配器131的触针134相连。滤波器170可以具有低通频率特性或带通频率特性。滤波器170允许来自仪表回路142的低频通讯信号通过适配器上的触针134，但是，滤波器170滤出或阻止高频噪声，使之不能到达适配器上的触针134。信号电流沿虚线172所标明的线路流经整流器194、感应器176、电阻器178、工业变送器、感应器180和仪表回路142。来自仪表回路的噪声(RFI/EMI)通过π节低通滤波器与大地182导通，π节低通滤波器由环路阻抗、感应器176和180、电容器184、186、188和190组成。在优选实施例中，提供独立导体192用于本地串行通讯信号。在变送器的几米之内，本地串行通讯信号可用作短距离的通讯。本地串行通讯信号可用作电路编程变送器，或用作相距很近的变送器之间的本地通讯。电容器194被连接在独立导线192和地182之间以提供EMI/RFI噪声监测。依据在仪表回路中所使用的数据通讯协议的频率，可使用不同类型的RFI/EMI滤波电路。
需要时，可在适配器上提供本地连接器196(以示意图示出)。本地连接器196允许本地指示器的本地连接，如通过整流器194的d’Arsonval计的运动。本地连接器196还允许经过仪表回路连接手持串行通信设备，如Rosemount 275型哈特式发报机，从而使技术人员可以进行检查、服务和诊断。本地连接196在弹性保护罩内可被布置为附加导线。或者，本地连接可沿由McCoy等所发明的美国专利5,710,552所示出的线路安置在密封的T-形适配器中，带有检修接头用于连接电路检查钩。
图5示出了安装在工业变送器202上的适配器200。适配器200与图2所示的适配器130类似，但在图5中，弹性套204向外延伸，包括一个防滴罩206和一个延伸套208。防滴罩206延伸到套筒210的外侧。防滴罩206在适配器200的套筒210的周围上方提供一种“伞”状保护。当液体211从延伸套208流向适配器200时，防滴罩206使液体偏向，如212所示那样滴掉，而不流到适配器200中。延伸套208足够长，可沿回路延伸到弹性套根部，延伸套的长度足可以使其弯曲超过90度。如此可允许滴到延伸套上的液体211沿着延伸套滴落，如214所示。由于延伸套208的未端朝向下方，这样就避免了重力迫使液体进入延伸套208的未端。
图6示出了包括电缆密封232的环境密封适配器230。电缆密封232是一个压缩套筒，挤压压缩套筒以在电缆234的周围形成密封。适配器230与图3所示的适配器相同，但是，适配器230允许本领域内的技术人员将仪表回路电缆234的端部装配到适配器230上。适配器230包括螺旋形压缩端部236、RFI/EMI滤波器，RFI/EMI滤波器包括线路板240和铁氧体套筒感应器242，铁氧体套筒感应器242被装配在穿通导体244外围。利用接合环248，适配器230被安装到接头246上。电缆密封232包括由压紧螺母252压紧的弹性密封250。
图7示出了带有与标准塞绳装置相连接的环形连接器276的环境密封适配器275。
适配器275是一环境密封仪表环路适配器，包括与工业变送器接头282内部的触针280相匹配的触孔278。适配器275还与塞绳装置(未示出)的第一线路端部相连，塞绳装置在环形连接器276处与仪表环路相连。
触孔278布置在硬质塑料绝缘支撑结构292中，用来与工业变送器上接头282内部的触针相匹配。
套筒284通过螺纹286拧紧到接头282上。套筒284有一个凸缘288面对接头282。杯状垫圈298位于凸缘288和端部282之间。杯状垫圈298有一个面向凸缘288的垫圈面300，垫圈面300包括一个密封槽299。
在杯状垫圈298的中心形成一个整体的环形连接器276。环形连接器276具有第二触针277，并通过RFI/EMI滤波器295与触孔278相连接。利用标准塞绳装置，环形连接器276被接入仪表环路中。
防液体弹性密封301被安装在密封槽299中，当套筒284旋到接头282上时用来密封凸缘288。弹性密封可以是一标准的O形环。
图8A和8B示出了用弹性材料模制的弹性防滴罩303。防滴罩303有一可使电缆304通过的中心通道302，并可在306处劈开，使得当电缆304被安装在如308所示的环境密封仪表环路适配器上后，防滴罩很容易在电缆304上滑动。防滴罩303用作适配器308的防液“伞”。防滴罩303径向延伸到适配器308外侧，有一圆锥斜面310和312用来促使水从适配器308之上排走。防滴罩303是图5所示整体防滴罩206的一个替代品。防滴罩303提供了防止湿气进入适配器308的额外手段。
在图2、3、5、6中的环境密封弹性套和图5、8A、8B中的防滴罩优选由弹性材料制成，如山都平热塑性弹性体(Santoprene)或莫诺热塑性橡胶(Monoprene)材料。支柱158、159优选由硬塑料制成，如Valox。
套筒上螺纹优选为1-1/8″-18-UNEF螺纹。图7所示的环形连接器276优选与ANSI B93.55M-1981(R1988)兼容，优选具有按照IEC 61076-2-101的性能特性。特别地，带有M12螺纹的适用于Euronorm EN 60947-5-2的连接器可用作环型连接器276。
利用本发明，通过拨出旧的变送器和插入新的变送器，即可方便地实现变送器的现场更换。并可实现快速、减少人为误操作的连接。连接快速并避免了使用线盒和庞大的接线板。
尽管本发明是参照优选实施例来描述的，但熟练工作者将会认识到，在不离开本发明的实质和范围的情况下可对本发明的形式和细节进行改变。一个实施例所示的特点可以适当地用于另一个实施例。
