具体实施方式
下面将详细描述本申请的各个方面的特征和示例性实施例。下面的详细描述中公开了许多具体细节，以便全面理解本申请。但是，对于本领域技术人员来说，很明显的是，本申请可以在不需要这些具体细节中的一些细节的情况下实施。下面对实施例的描述仅仅是为了通过示出本申请的示 例来提供对本申请的更好的理解。本申请决不限于下面所提出的任何具体配置和算法，而是在不脱离本申请的精神的前提下覆盖了元素、部件和算法的任何修改、替换和改进。在附图和下面的描述中，没有示出公知的结构和技术，以便避免对本申请造成不必要的模糊。
为了更好地理解本申请，下面结合图1至图4对本申请实施例提供的管道整流装置及管道进行详细描述。
图1是本申请实施例提供的一种管道整流装置的结构示意图，图2是本申请实施例提供的另一种管道整流装置的结构示意图。
请一并参阅图1和图2，本申请实施例提供了一种管道整流装置1，与管道的轴向呈预定角度设置于管道中。管道整流装置1包括基板11，基板11包括整流区111，整流区111设置有贯穿基板11的多个整流孔12，整流孔12沿流体的流动方向延伸。
可选地，基板11的形状为圆形、椭圆形、多边形或者不规则形状等，根据管道的横截面形状而定。基板11的材料为金属，例如钛合金或者不锈钢等，以满足流体流经基板11时的冲击强度要求。
管道整流装置1与管道的轴向呈预定角度设置，即基板11与管道的轴向呈预定角度设置。基板11上的整流孔12沿流体的流动方向延伸，以减小流体流经基板11的整流孔12时的压力损失。
当管道中的流体例如湍流经过管道整流装置1时，流体会被基板11上的多个整流孔12分成多股较小的流体，流经各个整流孔12后再汇合到一起。由于原来管道内的湍流流体被切割破坏，流体内部的小旋涡被打散，通过基板11后，各细小流体将以近似平行于管道的轴向方向流出。这样，大幅降低流体的湍流现象，将流体最大限度地整流为接近理想流体的层流流体，便于准确地测量流体流速，或者监测流体中是否有颗粒物质及颗粒物质的含量等相关参数。
本申请实施例提供的一种管道整流装置1，通过在基板11的整流区111设置贯穿基板11的多个整流孔12，可以将管道中的流体整流为接近理想流体的层流流体，便于后续精准测量管道中流体的相关参数。
进一步地，本申请实施例提供的管道整流装置1与管道的轴向之间的 预定角度可以为90°，即基板11垂直于管道的轴向设置，或者说，基板11垂直于流体的流动方向设置，使得整流孔12以垂直角度贯穿基板11，以使整流孔12沿流体的流动方向延伸，降低了基板11上的整流孔12的工艺制作难度。
进一步地，基板11的整流区111设置的多个整流孔12在整流区111呈阵列排布。整流区111的形状可以与基板11的形状类似，例如圆形、椭圆形、多边形或者不规则形状等，以提高流体的整流面积。
可选地，如图1所示，多个整流孔12可以在行方向对齐排布，也可以在列方向上对齐排布，还可以在行方向和列方向上对齐排布。由此管道中的湍流流体经过基板11上的多个整流孔12时，将被均匀切割为多条平行的小细流。
可选地，如图2所示，多个整流孔12可以在行方向交错排布，也可以在列方向上交错排布，还可以在行方向和列方向上交错排布。由此管道中的湍流流体经过基板11上的多个整流孔12时，将被均匀切割为更加琐碎的多条平行的小细流。
另外，整流孔12的形状呈圆形、矩形、椭圆形、多边形中的任一者。例如，图1所示的整流孔12的形状为矩形，图2所示的整流孔12的形状为圆形。
流体流经基板11时，为了提高流体的切割率，整流孔12的数量越多越好，相应地，相邻的整流孔12之间的中心距越小越好。但同时，基板11的结构强度需要能够抵抗流体的冲击力，故相邻的整流孔12之间的中心距需要提供足够的结构强度。为了平衡结构强度与切割率，相邻的整流孔12之间的中心距为L1，整流孔12的最大外径尺寸为L2，则L1/L2＝1.1～1.5。
可选地，相邻的整流孔12之间的中心距为L1与整流孔12的最大外径尺寸为L2的比值为：L1/L2＝1.2。例如整流孔12的形状为正方形，边长为2mm，相邻的两个整流孔12之间的中心距为2.4mm，即相邻的两个整流孔12邻近的边缘之间的距离为0.4mm，既能保证提高基板11提供足够的抵抗流体冲击力的结构强度，又能最大限度地提高流体的切割率。
另外，整流区111的形状与管道的横截面形状相同，便于流体在管道 与管道整流装置1之间顺利过渡。例如，管道的横截面为圆形，则整流区111呈圆形，如图1、图2中的圆形虚线所示。如管道的横截面为矩形，则整流区111呈矩形。
进一步地，为了最大限度地利用管道整流装置1的切割流体的功能，整流区111的面积小于或者等于管道的横截面面积。
由于流体流过管道整流装置1时会有压力损失，降低了流体的流动速率。为了使压力损失尽可能地小，例如小于5％，可选地，多个整流孔12的横截面面积之和为S1，整流区111的面积为S0，则S1/S0≥90％。
为了进一步降低流体流过管道整流装置1时的压力损失，基板11的厚度小于或者等于3mm。
另外，基板11还包括围绕整流区111的固定区112，管道整流装置1通过固定区112固定于管道中，结构简单、安装方便、成本低。
图3是本申请实施例提供的一种管道的剖面结构示意图，图4是图3所示的区域A的局部放大结构示意图。
请一并参阅图3和图4，本申请实施例还提供了一种管道，包括第一管段2、第二管段3和如前所述的管道整流装置1。
管道整流装置1设置于第一管段2与第二管段3之间，第一管段2内的流体流经基板11的整流区111后，以层流流体进入第二管段3。
进一步地，第一管段2沿自身轴向一端具有第一法兰盘21，第二管段3沿自身轴向一端具有第二法兰盘31，第一管段2和第二管段3通过第一法兰盘21与第二法兰盘31的配合相互连接，管道整流装置1通过基板11的固定区112固定于第一法兰盘21与第二法兰盘31之间。
参阅图4，可选地，第一法兰盘21或者第二法兰盘31中的任一者设置有容纳基板11的固定区112的第一凹槽C1，且第一凹槽C1的深度尺寸小于或者等于基板11的厚度尺寸，以便于将基板11的固定区112紧固于第一法兰盘21与第二法兰盘31之间。如图4所示，第二法兰盘31上设置有容纳基板11的固定区112的第一凹槽C1，第一法兰盘21盖合于第一凹槽C1，以将基板11压合于第一凹槽C1。
可选地，第一法兰盘21或者第二法兰盘31中的任一者还设置有容纳 另一者的第二凹槽C2，以便于将第一法兰盘21容纳于第二法兰盘31的第二凹槽C2中，或者将第二法兰盘31容纳于第一法兰盘21的第二凹槽C2中。如图4所示，第二法兰盘31上还设置有容纳第一法兰盘21的第二凹槽C2，第二凹槽C2的底面与第一法兰盘21接触。
可选地，第一法兰盘21与第二法兰盘31之间通过焊接连接为一体，以将第一管段2和第二管段3连接为一体的管道，其中第二凹槽C2的底面为焊接面。
可选地，第一法兰盘21或者第二法兰盘31中的任一者均不设置第二凹槽C2，直接将第一法兰盘21与第二法兰盘31焊接为一体的管道即可。
如果管道的材质为金属，则第一法兰盘21与第二法兰盘31之间通过金属焊料焊接为一个整体的管道。如果管道的材质为塑料，则第一法兰盘21与第二法兰盘31之间通过热铆焊接为一个整体的管道。管道整流装置1的基板11被压装于第一法兰盘21或者第二法兰盘31中的任一者的第一凹槽C1内，固定牢靠。
由此，第一管段2内原本杂乱无章的湍流流体被管道整流装置1的整流区111整流后，分为多个细小地平行的层流流体流入第二管段3内，从而可以更精准地测量管道中流体的相关参数。例如，管道整流装置1可以筛选出流体中的颗粒物质，从而获得颗粒物质的含量；通过测量任一个细小的层流流体的速率可以获得管道中所有流体的速率，提高了测量精度。
