Description

一种弯管型科氏流量计节点板 技术领域
本发明涉及节点板，具体的涉及一种应用于弯管型科氏流量计的节点板。
背景技术
在科氏质量流量计中，节点板将整个流量管分成多个区域，在两个节点板之间定义一个测量区域，利用这个测量区域的振动来感应流量，节点板处的振动最小，从而形成一个节点。为了保证测量的稳定性，振动应该限制内部，振动不通过外部零件如外壳和连接零件(如法兰)向外界传递。
已有的设计中，节点板的形状基本上都采用对称的方案，但是，对于弯管型的科氏流量计，如果我们对节点板处的振动进行分析，可以看出节点板处的振动变形相对于节点板的横轴并不对称，振动不对称会导致内部不平衡，振动会向外传播，相应的，外界的振动也会向内传播，影响测量性能。
鉴于此，本发明给出了一种应用于弯管型科氏流量计的节点板，用来补偿非对称的振动。
发明内容
本发明提供了一种弯管型科氏流量计节点板，其特征在于，所述节点板包括板体，所述板体包括至少两个贯穿孔，所述贯穿孔用于置放所述科氏流量计的弯管；
所述节点板的形状相对于由所述管穿孔的中心连线形成的轴不对称。
优选的，所述节点板还包括第一翻边，所述第一翻边竖直位于所述板体的第一侧。
优选的，所述第一翻边的宽度大于或等于所述板体的厚度。
优选的，第一翻边的高度大于所述板体的厚度。
优选的，所述节点板还包括第二翻边，所述第二翻边竖直位于所述板体的与所述第一侧相对的第二侧，所述第一翻边与所述第二翻边均位于所述板 体的顶部。
优选的，所述第二翻边的宽度小于所述第一翻边的宽度，和/或所述第二翻边的高度小于所述第一翻边的高度。
优选的，所述节点板还包括第三翻边和第四翻边，所述第三翻边竖直位于所述板体的第三侧，所述第四翻边竖直位于所述板体的第四侧，所述第三侧与所述第四侧相对，所述第三翻边与所述第四翻边均位于所述板体的顶部。
优选的，所述节点板第一侧的厚度大于与所述第一侧相对的第二侧的厚度。
优选的，所述节点板第一侧与所述管穿孔的中心连线的距离大于所述节点板第二侧与所述管穿孔的中心连线的距离，所述第一侧与所述第二侧相对。
本发明带来的效果如下：利用不对称设计的节点板产生的反向不对称的机械参数，对节点板处的非对称振动进行补偿，将振动尽量限制在测量区域内，从而外界条件不影响有用的振动信号，最终使得流量计的测量结果稳定性提高。

具体实施方式
使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
本发明实施例中提供的一种弯管型科氏流量计节点板，可应用于双弯管或者多弯管的科氏流量计，附图仅作为双弯管型科氏流量计节点板的示例， 多弯管型科氏流量计节点板为双弯管型科氏流量计节点板的简单扩展。如图1所示，双弯管型科氏流量计的弯曲角度α大于30度小于150度。节点板(NodePlate)A1、B1、C1、D1形状相同，如图2所示，包括板体，所述板体包括两个贯穿孔，所述贯穿孔用于置放所述科氏流量计的弯管，如图1所示，使用时，两个弯管穿过两个对应的贯穿孔，当节点板应用于多弯管型科氏流量计时，贯穿孔为多个，分别置放对应的科氏流量计的弯管。
节点板的形状相对于由所述管穿孔的中心连线形成的轴不对称。节点板的形状指的是立体形状，形状不对称可以由多种形式，参见下方的示例。
在一个示例中，所述节点板还包括第一翻边，所述第一翻边竖直位于所述板体的第一侧。第一翻边可以由节点板直接向上翻折一体成型，但当板体的厚度过大时(比如应用在大口径的流量计)，不宜折弯加工，因此第一翻边也可以是单独的元件通过焊接等方式与板体连接在一起。所述第一翻边的宽度Ws大于或等于所述板体的厚度H。如果第一翻边采用板体直接折弯后实现的方式，第一翻边的宽度通常等于板体的厚度。第一翻边的高度Hs至少大于1mm，通常大于节点板厚度H。由于振动变形不对称是由机械参数(MCK，质量、阻尼或刚度)的不对称造成的，用不对称设计的节点板会产生反向不对称的机械参数，进行补偿。通过第一翻边的设计，使得节点板的第一侧的刚度大于与第一侧相对的第二侧，从而对节点板处的不对称振动进行补偿。
在一个示例中，参见图3、图4，所述节点板还包括第二翻边，所述第二翻边竖直位于所述板体的与所述第一侧相对的第二侧，所述第一翻边与所述第二翻边均位于所述板体的顶部。所述第二翻边的宽度小于所述第一翻边的宽度，和/或所述第二翻边的高度小于所述第一翻边的高度，也就是说，需要保证第一翻边和第二翻边的尺寸不同，从而使得节点板的第一侧的刚度大于与第一侧相对的第二侧。通过在两侧均设置翻边，可以提高节点板整体的刚度。
在一个示例中，参见图5、图6，所述节点板还包括第三翻边和第四翻边，所述第三翻边竖直位于所述板体的第三侧，所述第四翻边竖直位于所述板体的第四侧，所述第三侧与所述第四侧相对，所述第三翻边与所述第四翻边也同样均位于所述板体的顶部。第三翻边和第四翻边的高度和宽度可以相同也可以不同。通过第三翻边和第三翻边的设计，使得板体的四个边缘均设 置翻边，增加了整体的刚度。
在一个示例中，参见图7，根据节点板不对称的原则，采用楔块方案的节点板同样适用本发明。节点板第一侧的厚度大于与所述第一侧相对的第二侧的厚度，即Hs>H。本方案可单独成立，也可以结合上述示例共同成立。
在一个示例中，内部空间允许的情况下，通过改变X轴单侧的尺寸或特征也可达到节点板不对称的目的，参见图8，所述节点板第一侧与所述管穿孔的中心连线X轴的距离Ws大于所述节点板第二侧与所述管穿孔的中心连线X轴的距离W，所述第一侧与所述第二侧相对。参见图9，也可以采用X轴两侧不同的特征实现节点板不对称。
对于本领域技术人员而言，显然本发明不限于上述示范性实施例的细节，而且在不背离本发明的精神或基本特征的情况下，能够以其他的具体形式实现本发明。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的，本发明的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本发明内。不应将权利要求中的任何附图标记视为限制所涉及的权利要求。
