Description

旋涡流量计
本实用新型为旋涡流量计,属于流量测量仪表,适用液体、气体、饱和蒸汽的流量计量。
目前使用的老式旋涡流量计小流量段偏高,如果小流量向下扩展,计量误差大,安装管路要求的非常严格,流量计的前后直管段要有足够的距离才能正常计量。
本实用新型针对上述问题,设计了一种旋涡流量计,这种流量计壳体(1)的两端口处采用缩径式,缩径角度为1°-10°,能提高流体的流速、扩展流量范围,小流量可扩展到原来的二分之一,解决了小流量向下扩展时计量误差大和安装管路要求严格等问题。
附图为旋涡流量计的结构示意图。
本实用新型是这样实现的(如图):一种旋涡流量计由壳体(1)、旋涡发生体(2)、传感器(3)和流量积算单元(4)组成,壳体(1)的两端口处的缩径角度为1°-10°。
本实用新型具有准确度高,测量范围宽,可靠性高,压力损失小,使用寿命长等优点。
下面结合附图描述一个实施例:壳体(1)铸造加工后,将加工合格的不锈钢旋涡发生体(2)插入壳体(1)内,用电焊焊接成一体,再将传感器(3)装在旋涡发生体(2)上端,用支架固定,流量积算单元(4)与传感器(3)引出端线接通后和壳体(1)用螺钉固定,装配完后喷漆。
