下面以固定科氏质量流量计的驱动器为例，说明本发明实施例提供的一种用于流量计部件的固定装置的使用过程。
如图5所示，当流量计部件1为科氏质量流量计的驱动器时，首先将第一固定件6穿过固定支架2上的第一安装槽孔5并插入驱动器内，将驱动器的两侧分别固定安装有固定支架2，然后将第二固定件9穿过平衡块4上的安装孔8和固定支架2上的第二安装槽孔7，将平衡块4固定到固定支架2的外侧，这样完成固定装置的组装，最后通过真空钎焊将固定支架2上的连接弧3固定到科氏质量流量计流量管上，从而完成驱动器的固定安装。此结构能使固定支架2和流量管的连接刚度沿流量管中面对称，避免了流量管工作振动过程中产生不理想的变形，同时提高了科氏质量流量计零点稳定性及整体性能。
由此可见，本发明实施例提供的一种用于流量计部件的固定装置中，固定支架2的一端开设有连接弧3，固定支架2通过连接弧3与流量计的流量管固定连接，且连接弧3关于竖直方向轴对称，即将固定支架2上与连接弧3相对的一端水平放置时，连接弧3被竖直轴线平分后的两段弧对应的圆心角相等，圆心角都为a°，这样当固定支架2通过连接弧3固定到流量计的流量管上时，能够保证固定支架2和流量管的连接刚度沿流量管的中面对称，有效避免了流量管在工作振动时，产生不理想的变形。流量计部件1的两侧分别固定有固定支架2，即流量计部件1通过两个固定支架2上的连接弧3固定到流量计的流量管上。当流量计部件1为科氏质量流量计上的驱动器时，将两个固定支架2分别固定到驱动器的两侧，并且将驱动器通过固定支架2上的连接弧3固定到科氏质量流量计的流量管上，这样完成驱动器的安装固定，此结构能使固定支架2和流量管的连接刚度沿流量管中面对称，避免了流量管工作振动过程中产生不理想的变形，同时提高了科氏质量流量计零点稳定性及整体性能。
上述具体实施方式，并不构成对本发明保护范围的限制。本领域技术人员应该明白的是，取决于设计要求和其他因素，可以发生各种各样的修改、组合、子组合和替代。任何在本发明的精神和原则之内所作的修改、等同替换和改进等，均应包含在本发明保护范围之内。
