Description

超声波计量蝶阀
技术领域
本发明涉及阀门及流体计量技术领域，尤其涉及一种超声波计量蝶阀。
背景技术
蝶阀是一种结构简单的调节阀，可用于低压管道介质的开关控制的蝶阀是指关闭件(阀瓣或蝶板)为圆盘，围绕阀轴旋转来达到开启与关闭的一种阀，阀门可用于控制空气、水、蒸汽、各种腐蚀性介质、泥浆、油品、液态金属和放射性介质等各种类型流体的流动。在管道上主要起切断和节流作用。蝶阀启闭件是一个圆盘形的蝶板，在阀体内绕其自身的轴线旋转，从而达到启闭或调节的目的。
目前，大多数蝶阀在流体管路中只用作切断、截止和改变流体的流动方向，然而，随着阀门行业的发展，碟阀的功能越来越难以满足市场的需求。现有管路中阀门和流量计绝大多数是分开安装，并且在安装流量计的管路前后需要空出一定长度的直管段或者采用其他稳流装置，而较短管路上再需同时安装碟阀和流量计时，往往难以实现或对工程提出了较高要求，采用这种安装方式还需要较多的管井用于后期维护，不仅大大增加了工程造价和人工费用，且维护费用也较高。另一方面，已安装碟阀的管路上再需加装流量计时，需要将深埋的管路挖出，断开后增加连接部件，如法兰，以将流量计增加到管路中，施工量大、程难度大且费用高昂。
发明内容
本发明的目的就是要克服现有的大多数蝶阀在流体管路中只用作切断、截止和改变流体的流动方向，管路中阀门和流量计绝大多数是分开安装的问题，提供一种超声波计量蝶阀，它具有阀门的功能，又可测量流体流量且不受流质影响、测量精度高、使用寿命长、结构简单、安装维护方便的特点。
为实现上述目的，本发明所设计的超声波计量蝶阀，包括阀体、设于阀体内的蝶板、带动蝶板转动的阀杆；所述蝶板上嵌设有用于测量流体流量的超声波传感器；所述超声波传感器包括成对的发送传感器和接收传感器，在蝶板上沿周向相对布置；或所述超声波传感器包括成组的发送传感器、接收传感器和反射片，在蝶板上沿周向布置，所述发送传感器发出的超声波经反射片反射至接收传感器。
优选地，所述阀杆的上端设有用于驱动阀杆转动的驱动电机或手柄。
优选地，所述超声波计量蝶阀还包括控制部分和电源部分；所述控制部分包括单片机和驱动电机控制模块；所述单片机内存储有录入的标准流量数据，单片机将发送传感器和接收传感器采集的数据进行处理，并将结果与标准流量数据进行比对，将比对结果反馈给驱动电机控制模块；驱动电机控制模块根据反馈的比对结果控制驱动电机工作。通过控制部分与驱动电机的配合，使得超声波计量蝶阀，不仅可以计量时实的流体流量，还可以根据实时流量来改变开阀的大小，从而自动调节流出流量，适用于对管道的统一管理及远程控制。
优选地，所述阀芯的一端与阀杆下端固定，另一端在背对阀杆的位置固定有固定轴；所述固定轴通过轴承与阀体连接。通过轴承的过渡作用，使得阀芯旋转更容易，开、关阀更省力。
本发明的有益效果是：超声波传感器的发送传感器发射超声波被接收传感器接收，超声波传感器在阀芯转动到开的位置时，测量管路中流体的流量。采用超声波传感器测量流体流量，测量精度不受流质影响，流体通孔内没有其他阻挡物，测量精度高，且结构简单，安装方便，使用寿命长，解决了管路中阀门和流量计分开安装的问题，降低了成本；还可以根据实时流量来改变开阀的大小，从而自动调节流出流量，适用于对管道的统一管理及远程控制。

具体实施方式
以下结合附图和具体实施例对本发明作进一步的详细描述。
实施例1
如图1、2所示，超声波计量蝶阀包括阀体1、设于阀体1内的蝶板2、带动蝶板2转动的阀杆3；蝶板2上嵌设有用于测量流体流量的超声波传感器；超声波传感器包括成对的发送传感器4和接收传感器5，在蝶板2上沿周向相对布置；阀杆3的上端设有用于驱动阀杆3转动的驱动电机(图未示)或手柄7。
超声波计量蝶阀还包括控制部分(图未示)和电源部分(图未示)；控制部分包括单片机和驱动电机控制模块；单片机内存储有录入的标准流量数据，单片机将发送传感器4和接收传感器5采集的数据进行处理，并将结果与标准流量数据进行比对，将比对结果反馈给驱动电机控制模块；驱动电机控制模块根据反馈的比对结果控制驱动电机工作。
阀芯2的一端与阀杆3下端固定，另一端在背对阀杆3的位置固定有固定轴9；固定轴9通过轴承8与阀体1连接。
实施例2
如图3所示，本实施例中超声波计量蝶阀结构基本和实施例1相同，区别在于超声波传感器包括成组的发送传感器4、接收传感器5和反射片6，在蝶板2上沿周向布置，所述发送传感器4发出的超声波经反射片反射至接收传感器5。
本发明的原理如下：
超声波传感器的发送传感器4发射超声波被接收传感器5接收，当阀门处于开启状态时，通过超声波在流体流经时的传播时间、传播途径的声道长度及其他相关常量可测量流体此时流经阀芯处的流量。
由于单片机内存储有录入的标准流量数据，该数据可以是安装前录入，也可以是后期维护管理时录入的更新数据，单片机将发送传感器4和接收传感器5采集的超声波的传播时间等数据进行处理和计算，得出实时流量数据，并将结果与标准流量数据进行比对，将比对结果反馈给驱动电机控制模块；驱动电机控制模块根据反馈的比对结果控制驱动电机工作，从而实现对管道流体流量的自动控制。
