Description

旋进旋涡流量计
技术领域
本实用新型涉及旋进旋涡流量计。
背景技术
旋进旋涡流量计已经发展很多年了,主要用于气体领域的测量。以往旋进旋涡流量计的壳体的气体入口处安装发生体,发生体采用的是螺旋式铝发生体,其发生体结构复杂,加工成本高,强度较低,在用于测量介质时其压损较高,上限流量偏低,不能适用于压力较高冲击力大的介质和一些高低温的场所,因此影响了旋进旋涡流量计的应用范围。
发明内容
本实用新型的目的在于:提出一种旋进旋涡流量计,该流量计的发生体加工简单,结构紧固,扩展旋进旋涡流量计的应用范围。
本实用新型的技术解决方案是:该流量计包括壳体和发生体,在壳体的气体入口处安装发生体,其特征在于:该发生体由不锈钢叶片和不锈钢芯体组成,一组不锈钢直叶片安装在不锈钢芯体的圆周面上组成发生体。
本实用新型的旋进旋涡流量计中,直叶片与芯体中心线成35度夹角。
使用时,流体经过不锈钢发生体将产生旋涡,由于发生体采用的是直叶形式,所以产生的旋涡更强劲,使得探头得到的信号强,损失的压损小,有效的提高了量程范围。
本实用新型的不锈钢直叶片发生体加工简单,成本低廉,结构紧固,提高了流量计的上限量程,降低了压力损失,增强了发生体耐冲击的能力,适应高低温恶劣的环境中使用,扩展了旋进旋涡流量计的应用范围。
附图说明
图1为本实用新型结构示意图。
图2为图1的发生体示意图。
图3为图2的芯体示意图。
图中:1 壳体,2 发生体,3 不锈钢叶片,4 不锈钢芯体,
具体实施方式
如图1-3所示,该流量计包括壳体1和发生体2,在壳体1的气体入口处安装发生体2,其特征在于:该发生体2由不锈钢叶片3和不锈钢芯体4组成,一组不锈钢直叶片3安装在不锈钢芯体4的圆周面上组成发生体2。
本实用新型的旋进旋涡流量计中,直叶片3与芯体4中心线成35度夹角。
使用时,流体经过不锈钢发生体2将产生旋涡,由于发生体采用的是直叶形式,所以产生的旋涡更强劲,使得探头得到的信号强,损失的压损小,有效的提高了量程范围。
