Description

用于流量计的测量配件
技术领域
本发明涉及一种用于流量计的测量配件，所述测量配件用于基于声波检测液态或气态介质的流量。
背景技术
基于(超)声波测量技术的流量计是已知的。脉冲状(超)声波信号借助于(超)声波变换器产生以及沿流动方向和逆着流动方向通过介质传输。分析处理声波信号沿两个传输方向的传输时间之差以用于确定介质的流量。这种基于超声波的流量计根据传输时间差原理工作。
存在不同的设计方案。一方面已知了作为真正意义上的流量计且仅仅确定介质流量的装置。另一方面，也存在例如形式为热量计和冷量计的能量计算器，其中将根据上述原理确定的流量与至少一个额外的温度测量值结合起来，以便由此确定通过介质输入的(热或冷)能量。这种能量计算器在此也可以理解为专用设计的流量计。
声波信号可以在不同的传输路径上通过待检测的介质传输。在一些设计方案中，声波信号倾斜地穿过介质，然而也可以穿过那些其中存在用于声波信号的偏转或反射位置的介质，从而整体上得到例如U形或W形的声波信号传输路径。然而也已知了具有较复杂的声波信号－传输路径的设计方案。例如在EP 1 337 810 B1中描述了一种流量计，其中给出一种通过待检测的介质的、声波信号的大致螺旋状的传输路径，以便尽可能地得到介质的完整的流量轮廓。
还已知超声波流量计的其它设计方案，其具有能更换的测量插件。在EP 0 890826 B1中描述了一种塑料制的盆状的测量插件，具有插入在特殊袋部中的反射片。此外，在EP 1 978 337 B1和在EP 2 278 281 A1中描述了超声波流量计，所述超声波流量计包含具有测量管和两个反射器支架的测量插件，其中尤其是由塑料制成的测量插件被轴向地推入相应的超声波流量计的分开的壳体中。
虽然已经已知了多个基于超声波的流量计，然而仍存在在这种设备的使用性、操纵－/运行安全性、测量精度和/或制造成本方面对改进的解决方案的需求。
发明内容
本发明的任务在于，给出一种用于前述类型的流量计的测量配件，所述测量配件相对于已知的设计方案得到进一步改进。
为了完成该任务，给出一种对应于权利要求1所述特征的测量配件。根据本发明的测量配件包括设计为塑料部件的基本上为管状的主部件，所述主部件具有：与介质的流动方向基本上平行的中心纵轴；设计为管状主部件的一体的/构成整体的组成部分的且布置在内部的真正的测量段；以及用于两个声波变换器的、存在于主部件的外侧上的两个变换器接触面，其中沿流动方向观察，两个变换器接触面中的一个布置在两个变换器接触面中的另一个之前，测量段至少部分地在位于中心纵轴上的两个变换器投影位置之间延伸，所述变换器投影位置分别通过两个相关变换器接触面在中心纵轴上的竖直投影得到。此外，根据本发明的测量配件还包括从外部插入管状主部件的两个支架接纳开口中的、伸入到管状主部件的内部的且分别设计为塑料部件的两个反射器支架，其中支架接纳开口中的每个分别配属于变换器接触面中的一个。反射器支架中的每个分别包括具有上部件外周的支架上部件以及一支架下部件，该支架下部件的形式为伸出上部件外周的且在安装状态中贴靠在包围相关的支架接纳开口的开口边缘上的安装凸缘。在管状主部件的壁部的外侧上存在两个分别包围支架接纳开口的安装底座，其中在相应的安装底座的区域中包围相应的支架接纳开口的开口边缘具有基本上平坦的边缘面，反射器支架之一的安装凸缘尤其是贴靠在该边缘面上。相应的反射器支架的安装凸缘设有朝向支架上部件的方向突出的安装接片，开口边缘在相应的安装底座的区域中设有包围相应的支架接纳开口的且与安装接片对应的安装槽。
已经已知，如此设计的测量配件能特别价廉地制造，其中同时得到高的耐压性。在此，测量配件尤其可以由塑料注塑分部件组成。测量段一件式在内部形成在管状主部件上或者设计为管状主部件的一体的组成部分。由此减少了单个组件的数量，这对制造成本是有利的。管状主部件尤其也可以理解为流量计的壳体。其在运行状态中插入待检测的介质流经其中的管道中。为了连接至管道，管状主部件尤其还具有入口管接头和出口管接头，其中两个管接头优选分别配设有螺纹。
两个变换器接触面的投影分别垂直于中心纵轴，即尤其沿相对于中心纵轴的径向，通过变换器接触面得到两个位于中心纵轴上的变换器投影位置。变换器接触面尤其设计为用于相应一个(超)声波变换器的接触面，其中管状主部件的壁部在变换器接触面的区域中尤其是不开口的，即例如不具有用于插入(超)声波变换器的穿通开口。管状主部件的壁部至少在变换器接触面的区域中优选是能透过声音的或者声音可透过的。该壁部区域优选设计用于，传输来自和到达位于变换器接触面上的(超)声波变换器的声波信号，或者使所述声波信号通过。
两个反射器支架插入其中的支架接纳开口尤其是完全穿过管状主部件的管壁部的开口，即尤其是穿通开口。
具有突出的安装凸缘的反射器支架的结构有利于把反射器支架安装到管状主部件上且随后有助于在这些组件之间的长期良好的且尤其是紧密的结合。
相对于具有安装底座(该安装底座具有基本上平坦的边缘面)的管状主部件的结构来说，边缘面的平坦的面几何形状尤其可以通过安装槽中断，然而这在此也仍然应该属于概念“基本上平坦的边缘面”的范围内，恰恰与此外给出的管状主部件的尤其是圆柱形的外部几何形状不同。平坦的边缘面也便于把反射器支架安装到管状主部件上以及有助于在这些组件之间的长期良好的且尤其是紧密的结合。
一方面通过在相应的安装凸缘上的安装接片以及在相应的安装底座上的与此对应的安装槽得到了插入的反射器支架在管状主部件中的良好的固定。另一方面，安装槽阻止了，在固定两个组件时在必要时使用的粘合剂或者在固定两个组件时借助于焊接工艺在必要时熔融的材料与在运行期间在管状主部件内部被引导的介质接触。粘合剂或熔融材料可以被收集在安装槽中，从而阻止了介质可能被污染的情况。尤其当介质是水、尤其是饮用水，而测量配件应用在其中的流量计是水量计时，这是重要的。
根据本发明的流量计的有利的设计方案由权利要求1的从属权利要求所述的特征得到。
在一有利的设计方案中，反射器支架牢固地且尤其是不可拆卸地与管状主部件连接。反射器支架优选还相对于介质通过支架接纳开口的流出而与管状主部件紧密地连接。这有利于测量配件的高的耐压性。此外，这在测量配件的作用良好性以及操纵可靠性方面是有利的。
根据另一个有利的设计方案，反射器支架和管状主部件被彼此焊接或粘合。由此实现了反射器支架特别好地处于支架接纳开口中以及也实现了特别持久的牢固且紧密的连接。
根据另一个有利的设计方案，支架接纳开口中的每个分别基本上与变换器接触面之一对置。这种彼此对置的布置尤其涉及中心纵轴或者包含中心纵轴的平面。在此，涉及一种具有尤其也是简单的声波路径的、构造简单的结构。然而，原则上也可以设想支架接纳开口的和所属的变换器接触面的其它几何形状的布置，例如相对彼此倾斜错开的布置。
根据另一个有利的设计方案，管状主部件和反射器支架分别设计为由塑料制成的注塑件。因此，这些组件可以简单且价廉地制造。此外，管状主部件(包括内部内置的测量段)可以简单地脱模/模制，也就是说从注塑模型去除。该随后才插入的反射器支架并不会表现为在脱模时的阻碍。管状主部件的几何形状、尤其是其内部几何形状优选极其好地适合于价廉的注塑制造。这同样也适用于反射器支架。
根据另一个有利的设计方案，反射器支架中的每个分别具有注入的或——尤其是随后、例如在完成了反射器支架的制造之后——插入的反射元件或尤其是固有的反射面。由此实现了从声波变换器发射的声波信号的偏转。相应地，反射元件同样可以称为偏转元件以及反射面称为偏转面。例如，反射元件可以是金属反射器或者是陶瓷反射器。固有反射面尤其可以由此实现，即反射器支架连同该反射面由金属纤维增强的塑料制成，例如喷射而成。根据另一个有利的设计方案，反射器支架中的每个分别可以具有尤其是闭合的、具有另一种声学特性的区域作为支架材料，另外的反射器支架由该支架材料制成，以便通过这种方式得到期望的反射性能。该具有另一种声学特性的区域例如可以是闭合的气泡。
根据另一个有利的设计方案，每个反射器支架设有定位辅助件。该定位辅助件尤其是例如形式为几何元件、优选形式为安置在相应的反射器支架的安装凸缘上的定位凸起的机械定位辅助件。在包围支架接纳开口的开口边缘上尤其存在一对应于定位凸起的定位凹部或定位凹槽。通过定位辅助件可以阻止反射器支架的错误安装。则反射器支架可以有利地仅利用正确的定向插入支架接纳开口中。
根据另一个有利的设计方案，测量段至少也由管状主部件的在内部变窄的分部段形成，其中在变窄的分部段的区域中，在管状主部件上在外部布置有相对于中心纵轴沿径向向外延伸的增强肋，以替代封闭壁部形式的圆柱形的外部几何形状。由此可以减小壁部所需的材料量。除了节省成本之外还使得重量更轻，同时机械稳定性并未减小或并未显著减小。
根据另一个有利的设计方案，为了连接至管道系统，在管状主部件上存在入口管接头和出口管接头，所述入口管接头和出口管接头分别配设有外螺纹，其中在管状主部件上在外部仅存在唯一一个工具法兰，用于在制造与管道系统的入口侧和出口侧的螺纹连接期间，借助于工具固定管状主部件。通过这些措施同样可以节省材料且得到成本和重量减小。
根据另一个有利的设计方案，支架接纳开口分别具有未被占用的开口面，其面积相对于管状主部件的额定－管道横截面处于20％至50％之间的范围内。管状主部件的额定－管道横截面尤其根据在管状主部件的入口管接头和/或出口管接头处得到的管道内直径确定。额定－管道横截面尤其等于管道系统的额定－管道横截面，为了安装，测量配件在管道系统中被确定且在管道系统中在运行期间引导或运输液态或气态介质。在支架接纳开口的开口面积的所述大小比例中，一方面支架接纳开口可以通过插入的反射器支架气密地(也就是说，尤其是在运行期间相对于液态或气态介质的排出密封地)闭合。另一方面，反射器支架以及尤其是其反射元件或反射面大到足够检测在运行期间入射的声波信号的至少一大部分，并且以期望的方式偏转。对气密的闭合来说，期望尽可能小的开口面积，而对声波检测和偏转来说，尽可能大的面积是优选的。上述尺寸说明在此表现为这两个矛盾的布置之间的可看出的良好的妥协。
附图说明
由如下根据附图对实施例的描述得到本发明的其它特征、优点和细节。附图示出：

图2以剖视图II－II示出根据图1的测量配件；
图3以透视图示出根据图1和2的测量配件；以及
图4以透视图示出根据图1至3的在安装至测量配件中之前的反射器支架之一。
具体实施方式
在图1至4中彼此对应的部件具有相同的附图标记。在下文中具体阐述的实施例的细节本身也可以表示一发明或者是发明主题的一部分。
图1至3中示出用于基于(超)声波的流量计的测量配件1的实施例。测量配件1包括基本上为管状的主部件2以及两个反射器支架3和4，所述反射器支架插入管状主部件2中且与管状主部件不可拆松地连接。为其设置了测量配件1的流量计用于检测在运行期间流经管状主部件2的液态或气态介质的流量。该介质沿流动方向5经过管状主部件2，所述流动方向定向为基本上平行于管状主部件2的中心纵轴6。管状主部件2包括测量段7作为一体的组成部分，该测量段布置在管状主部件2的内部作为变窄的分部段。
管状主部件2在其壁部16的外侧上具有两个变换器接触面8和9，在按照规定的插入期间在基于声波的流量计中相应一个在图1至3中并未一起绘出的(超)声波变换器贴靠在所述变换器接触面上。变换器接触面8和9分别通过密封槽包围。与变换器接触面9相邻地设有穿通开口9a用于接纳温度探测器。沿流动方向5观察，变换器接触面8布置在变换器接触面9之前。此外，测量段7位于两个变换器投影位置10和11之间，所述变换器投影位置分别通过相应的变换器接触面8或9在中心纵轴6上的相对于中心纵轴6垂直的投影12或13得到。
相应一个包含在管状主部件2中的支架接纳开口14或15配属于变换器接触面8和9中的每个。支架接纳开口14和15分别设计为穿通开口，所述穿通开口完全穿过管状主部件2的壁部16。在这两个支架接纳开口14和15中插入反射器支架3和4。即变换器接触面8和9同样分别属于反射器支架3和4之一。在示出的实施例中，支架接纳开口14和15中的一个以及反射器支架3和4中的一个相对于中心纵轴6都与每个变换器接触面8或9对置。
反射器支架3和4中的每个在安装状态中朝向相关的变换器接触面8或9的正面上具有形式为金属或陶瓷片的随后被插入的反射元件17或18。反射元件17和18相对于中心纵轴6倾斜地定向，尤其是倾斜了45度，以便朝向测量段7的方向或者朝向相关的变换器接触面8或9的方向使声波信号偏转。在另一个未示出的实施例中，可以取代分开的反射元件17和18而存在相应一个固有的反射面作为相关的反射器支架3或4的组成部分，以便实现声波信号的偏转。
两个反射器支架3和4结构相同。图4中以透视图示例性示出未插入反射元件17的反射器支架3。该反射器支架包括支架上部件19和支架下部件20作为一件式彼此连接的组成部分。支架下部件20设计为安装凸缘，该安装凸缘在支架上部件19的外周上侧向伸出，且具有朝向支架上部件19的方向伸出以及完全包围支架上部件19的安装接片21。此外，在支架下部件20的安装凸缘上布置了形式为尤其朝向支架上部件19的方向略微伸出的定位凸起22的定位辅助件。支架下部件20的安装凸缘具有矩形或正方形的外轮廓，相反支架上部件19至少在其正面上具有基本上圆形的外轮廓。像从图1和3能看出的那样，支架上部件19设计为空心的。空腔23从在安装状态中处于外部的侧面(＝在图4中被遮盖的底面)朝向支架上部件19的设有反射元件17的正面的方向延伸。空腔23用于节省材料和减小重量。
作为反射器支架3和4的安装凸缘的对应件，在管状主部件2的外侧上存在安装底座24和25，所述安装底座如此包围支架接纳开口14和15，使得相关的支架接纳开口14和15的开口边缘具有平坦的边缘面。安装底座24和25具有矩形或正方形的外部轮廓，所述外部轮廓对应于反射器支架3和4的支架下部件20的安装凸缘的外部轮廓。此外，安装底座24和25配备了包围相应的支架接纳开口14和15的安装槽26。存在于两个支架接纳开口14和15处的管状主部件2上的安装槽26对应于反射器支架3和4的安装接片21。在插入状态中，反射器支架3和4的支架下部件20的安装凸缘抵靠在包围具有平坦边缘面的支架接纳开口14和15的安装底座24和25上。在此，安装接片21接合在安装槽26中。定位凸起22同样接合在存在于安装底座24和25上的对应的定位凹部27中，由此保证了，相应的反射器支架3或4以正确的安装位置插入。反射器支架3和4以其相应的支架上部件19伸出至管状主部件2的内部中。
在该示出的实施例中，管状主部件2和反射器支架3和4分别是塑料注塑件。例如，使用聚邻苯二甲酰胺(PPA)、聚苯硫醚(PPS)或者聚芳砜，例如聚亚苯基砜(PPSU)作为塑料材料。可选地，也可以向该塑料材料混入金属纤维用于增强，尤其在反射器支架3和4中，即用于有利地调节或增强反射性。尤其可以涉及金属纤维增强的塑料材料。此外，塑料材料尤其可以设计为部分结晶的或无定形的形式。管状主部件2和反射器支架3和4的几何形状极其适合用于注塑制造。这些构件在其注塑制造之后尤其可以容易地且在没有附加措施的情况下从注塑模具去除或取下。
在其注塑制造之后，将这些组件组合且牢固地彼此连接。在插入的反射器支架3和4和管状主部件2之间尤其存在焊接连接或粘合连接。这种连接是不可拆松的且相对于在运行期间在测量配件1的内部中被引导的介质的排出是紧密的/密封的。两个反射器支架3和4的支架下部件20分别气密地封闭支架接纳开口14和15。支架接纳开口14和15分别具有未被占用的开口面AF，在示出的实施例中，其面积相对于管状主部件2的额定－管道横截面AN占约26％。在此在入口侧的区域中基于管状主部件2的内直径D1计算出额定－管道横截面AN。
安装槽26具有略大于安装接片21的接片长度的槽深度，从而在插入状态中保留小的槽空腔28。该槽空腔28用于接纳(多余的)塑料或者用于接纳为了建立焊接连接而熔融的材料。由此阻止了，粘合材料或者熔融材料到达管状主部件2的内部中并在那里在运行期间会与介质接触。因此可靠地避免了污染介质。
管状主部件2在其外侧上在分部段的区域(其在内部变窄且形成测量段7)中不具有封闭壁部形式的圆柱形的外部几何形状。相反仅存在个别的增强肋29，所述增强肋径向向外延伸。与未示出的、其中在该分部段中壁部由实心材料制成的备选实施方案相比，增强肋29保证了在材料消耗和重量较小时类似的机械稳定性。
为了连接至管道系统，管状主部件2具有入口管接头30和出口管接头31，所述管接头分别具有外螺纹。为了能够在制造与管道系统的螺纹连接期间把管状主部件2保持在期望位置中，在管状主部件2的外侧上一件式安置了径向伸出的工具法兰32。就工具法兰32来说仅存在唯一的这种工具法兰。在示出的实施例中，该工具法兰布置为与入口管接头30相邻。然而备选地，其也可以定位在另外的位置处。放弃在其它情况下在出口管接头31处常见的第二工具法兰带来了材料节省和重量减轻。
总之，测量配件1仅由很少的单个组件组成，该单个组件还可以极好地制造为成本有利的塑料注塑件。此外有利的是，把测量段7内置到管状主部件2中，由此省去了在其它情况下常见的分开的测量段－构件。测量配件1的特征还在于小的重量和低的材料消耗。在此，测量配件1是极其价廉物美的构件。
