Description

技术领域
本发明涉及一种流体测量装置领域，特别是一种可冗余测量的智 控涡轮流量计。
背景技术
随着新能源的应用， 在城市、 乡镇已经广泛地使用自来水、管道 热水和管道燃气， 特别是天然气这一新能源的应用给用户带来了方 便， 现阶段天然气流量测量仪表的种类较多， 涡轮流量计就是其中的 一种， 由于涡轮流量计的结构紧凑、 重复性好、 范围度宽、 精度高、 元件零点漂移小，抗干扰能力好的特点得到了在天然气流量计量领域 上的广泛的应用。但是， 普通涡轮流量计的缺点也在天然气的计量过 程中日益突出，主要是目前涡轮流量计的叶轮在卡堵时由于不能测量 和计量， 造成计量数据和实际流量发生偏差， 引起贸易纠纷， 目前， 也有通过多加装一块相同仪表的方法来解决， 但这种方法加装复杂、 增加了多处泄漏点、大大提高了设备购置的成本。 因此普通涡轮流量 计存在的问题需要加以解决。
发明内容
本发明的目的是提供一种可冗余测量的智控涡轮流量计，解决涡 轮流量计测控过程中，叶轮卡塞故障时不能连续计量，管线泄漏点多， 检修不及时极易产生贸易纠纷的问题。 为实现上述目的， 本发明采用如下技术方案解决以上技术问题， 一种可冗余测量的智控涡轮流量计， 包括壳体、 叶轮、信号转换器和 调节阀， 叶轮安装在壳体内， 调节阀一体化安装在壳体的一端， 信号 转换器对测控信号进行处理， 还包括两只超声波探头， 分别一体化地 安装固定在壳体上。
两只超声波探头固定安装在叶轮和调节伐之间的壳体上，所述超 声波探头同壳体的轴向成 45度角安装，分别安装在壳体径向的两侧， 并且两只超声波探头的轴向中心线对齐， 保持在壳体轴向同一平面 内。
超声波探头可以螺纹或焊接安装。
超声波探头可以实现对流体的流量进行冗余测量，当涡轮流量计 出现叶轮卡塞故障时，通过通用电路模块对涡轮流量计信号和超声波 探头信号进行比对后， 实现用超声波探头继续计量。
本发明的有益效果是采用一体化的涡轮流量计、调节伐和超声波 探头结构， 实现在涡轮流量计叶轮卡塞故障时也能够连续计量， 减少 贸易结算纠纷， 增加涡轮流量计的检修反应时间， 减少了流量测控管 线的泄漏点。
附图说明
图 1为本发明实施例的结构主视图。
图 2为本发明实施例的结构俯视图。
图 3为本发明实施例的 A向剖面结构示意图。 其中： 1-壳体， 2-定位壳， 3-信号转换器， 4-调节阀， 5、 6-超 声波探头， 7-叶轮。
具体实施方式
下面结合附图详细说明本发明的优选实施例。
本实施例如图 1、 图 2、 图 3所示， 一种可冗余测量的智控涡轮 流量计， 包括壳体 1、 叶轮 7、 信号转换器 3、 调节伐 4和超声波探 头 5、 6。 叶轮 7设置在壳体 1 内， 调节阀 4的阀芯设置在一段加长 的壳体 1内，定位壳 2的一端与阀芯所在的壳体 1一端通过法兰连为 一体， 壳体 1和定位壳 2的另一端也设有法兰以便和管道连接， 调节 伐 4选择为电动调节伐， 也可根据测控需要选择气动或液动调节伐， 超声波探头 5、 6同壳体 1的轴向成 45度角安装， 分别安装在壳体 1 径向的两侧， 并且两只超声波探头 5、 6的轴向中心线对齐， 保持在 壳体 1轴向同一平面内， 超声波探头 5、 6和壳体 1通过螺紋连接， 超声波探头 5、 6自带保护套管， 也可以给超声波探头 5、 6另设保护 套管。
涡轮流量计的流量信号通过信号转换器 3 处理后结合二次仪表 进行智能显示、 远传、 通信和通过调节阀进行测控； 超声波探头 5、 6平时处于通电冗余状态， 当涡轮流量计的叶轮 7因为卡塞出现故障 时，涡轮流量计信号和超声波探头信号通过设置在信号转换器 3中的 比较电路模块进行对比， 使信号转换器 3选择采用超声波探头 5、 6 的测量值， 从而不因涡轮流量计的叶轮 7 卡塞而中断流量测量和累 计， 有利于争取检修时间而又不影响供料， 消除流量计量误差引起的 贸易纠纷， 另外超声波探头 5、 6在壳体 1上一体化的安装结构很好 地减少了流量测量系统的泄漏点。
