图3是透平减压机组的一个实施例的简化示意图。
在详细描述实施例之前，应该理解的是，本发明不限于本申请中下文或附图中所描述的详细结构或元件排布。本发明可为其它方式实现的实施例。而且，应当理解，本文所使用的措辞及术语仅仅用作描述用途，不应作限定性解释。本文所使用的“包括”、“包含”、“具有”等类似措辞意为包含其后所列出之事项、其等同物及其它附加事项。特别是，当描述“一个某元件”时，本发明并不限定该元件的数量为一个，也可以包括多个。
图1是透平减压动力装置的一个实施例的示意图。所述动力装置包括外壳10，透平12，液压泵14，液体输入管16，液体输出管18以及液压马达20，其中透平12和液压泵14均设置于外壳10内，且透平12与液压泵14驱动连接，这样，进入外壳10的管道气（例如天然气，液化气等）推动透平12旋转，继而驱动液压马达20运转。液体输入管16穿过外壳10并与液压泵14连通，液体输出管18穿过外壳10并与液压泵14连通，液压马达20设置于外壳10外并与液体输出管18连通，液体从液体输入管16进入液压泵14，经液压泵14压缩成高压液体从液体输出管18输出，输出的高压液体驱动液压马达20运转。
外壳10包括管道气入口22以及管道气出口24。管道气入口22与上游管道连接以接收上游来气，管道气出口24与下游管道连接以向下游输出膨胀后的管道气。
在本实施例中，外壳10包括基本呈圆柱形的外壳主体26以及安装至外壳主体26的管道气入口部28。管道气入口部28的一端30（下称管道气入口部连接端30）连接至外壳主体26，而远离外壳主体26的另一端设置上述管道气入口22。管道气入口部连接端30可以可拆卸地方式，例如法兰安装至外壳主体26。管道气入口22的直径小于管道气入口部连接端30的直径。优选的是，管道气入口部28具有呈流线型曲面的内表面32。
在所示的实施例中，透平12设有两级，一级透平包括第一级导向器34和第一级动叶36，二级透平包括第二级导向器38和第二级动叶40。其中，第一级导向器34和第二级导向器38与外壳10（例如，外壳主体26）固定，例如第一级导向器34和第二级导向器38的外圈焊接或以其它方式固定至外壳主体26的内圆表面。第一级动叶36和第二级动叶40固定在一转轴42上以在管道气的推动作用下绕一旋转轴转动。
在其它实施例中，根据实际需要，透平12可以仅设置一级或多于两级。
在所示的实施例中，外壳10内设置一内壳体44，透平12和液压泵14均安装在内壳体44内，从管道气流向看，透平12设置在液压泵14下游，外壳10内表面与内壳体44外表面之间形成流道45。内壳体44在轴向上的至少两个位置相对于外壳10固定。在靠近管道气入口22的一端，液体输入管16和液体输出管18与外壳10焊接固定，同时液体输入管16和液体输出管18与内壳体44内的液压泵14连通，液体输入管16和液体输出管18与内壳体44之间也是固定关系（例如焊接固定），因此，液体输入管16和液体输出管18可作为支撑内壳体44的元件；在靠近管道气出口24的一端，内壳体44被第一级导向器34和/或第二级导向器38支撑。
上述动力装置可以使用在管道气门站（如城市门站）中。在这里，上游来气的压力将被降低。本发明是利用管道气在经过透平膨胀之后降低压力的。为了满足管道传输的管道气压力要求，经透平膨胀降压的管道气的压力需要维持在预定值。根据输气站在整个管道传输中的不同位置，在此所述的预定值是不同的。例如，管道气压力可以从10Mpa降压至4MPa、从4MPa降压至2.5MPa或从2.5MPa降压至1.6MPa，并可在一定范围内浮动。应当理解的是，在一些输气站，经过调压的管道气压力可以维持在其它预定值或预定范围。
在有些情况下，下游用气量是不断变化的，因此会造成经透平膨胀降压的管道气的压力波动。为了维持其压力，如图1所示，可在透平12上游设置一个阀芯46，阀芯46用以根据透平12下游的管道气的压力调节进入透平12的管道气的流量，以此维持调压后的管道气压力在预定值或预定范围内。
阀芯46也设置在外壳10内并正对管道气入口22。阀芯46的外表面与外壳10的内表面32定义输入管道气通道48。为了形成均匀的管道气通道48，阀芯46外表面也形成流线型表面，使阀芯46在与进气方向相反的方向上呈渐缩的锥状。在一些实施例中，输入管道气通道48的截面积与流道45的截面积实质上相同。在一些实施例中，上游管道、输入管道气通道48和流道45的截面积实质上相同。保持相同的截面积，可以尽量防止管道气在进入透平前发生膨胀，从而提高动力装置的运作效率。
在本实施例中，阀芯46可根据透平12下游的管道气压力相对于透平12移动以改变输入管道气通道48的横截面积从而改变输入的管道气流量，以此调节透平12下游的管道气压力。阀芯46的移动可以采用多种方式来实现。在所示的例子中，阀芯46采用可伸缩设计，包括锥状头部50和与锥状头部50连接的圆柱形滑动连接部52。该圆柱形滑动连接部52可与一腔体滑动连接，使锥状头部50靠近或远离管道气入口22，从而减小或增加管道气流量。在所示的实施例中，该腔体是内壳体44或者说为内壳体44的一部分。如果锥状头部50进一步向管道气入口22移动，则可以完全堵住管道气入口22，这将使本发明具有管道气开关功能。
透平12上游和下游可分别设置压力传感器54、56以检测透平12上游和下游的管道气压力，并根据该检测的压力以电动方式驱动阀芯46进行上述用以调节流量的移动。
阀芯46的活动也可以根据下游的压力采用杠杠式机械驱动。
透平12上游和下游还可分别设置温度传感器58、60以检测透平12上游和下游的管道气温度。根据透平12上游和下游的压力差和温度差以及发出的电量可计算管道气的流量，因此本发明可以作为流量计。
图2是透平减压机组的一个实施例的简化示意图。如图2，,所述透平减压机组包括外壳10，透平12，液压泵14，液体输入管16，液体输出管18，液压马达20以及发电机61。其中，外壳10、透平12、液压泵14、液体输入管16、液体输出管18及液压马达20的构造可以与图1的实施例中的相同，发电机61位于外壳10之外并与液压马达20连接，当所述机组运作时，液压泵14驱动液压马达20运作继而驱动发电机61使其发电。
在另一实施例中，本发明提供了一种透平减压机组，所述透平减压机组包括外壳10，透平12，液压泵14，液体输入管16，液体输出管18，液压马达20以及水泵。其中，外壳10、透平12、液压泵14、液体输入管16、液体输出管18及液压马达20的构造可以与图1的实施例中的相同，所述水泵位于外壳10之外并与液压马达20连接，当所述机组运作时，液压泵14驱动液压马达20运作继而驱动所述水泵。
图3是透平减压机组的一个实施例的简化示意图。如图3，所述透平减压机组包括外壳10，透平12，液压泵14，液体输入管16，液体输出管18，液压马达20，抽风机62以及换热器64。其中，外壳10、透平12、液压泵14、液体输入管16、液体输出管18及液压马达20的构造可以与图1的实施例中的相同。抽风机62与液压马达20连接以被液压马达20驱动，抽风机62的输入能源来源于液压马达20的输出动能。换热器64一端与抽风机62连通，另一端与膨胀后的管道气连通。当所述机组运作时，液压泵14驱动液压马达20运作，液压马达20带动抽风机62，抽风机62鼓动的空气进入换热器64与减压膨胀后并进入换热器64的管道气进行逆流式热交换，对减压膨胀后的管道气进行加温。
在管道气传输过程中，温度也是一个需要维持在预定范围内的参数，在一些低温环境下，经常需要对传输中的管道气进行加温。管道气经透平减压后管道气会发生膨胀且温度会大幅降低，不利于管道气的传输。本发明利用抽风机62及换热器64，既可对膨胀后的管道气进行加温，利于管道气的传输，且抽风机62及换热器64的动力能源来源于透平减压动力装置本身，实现能源利用的最大化。
综上所述，本发明提供了一种透平减压动力装置，在燃气管道内设置透平和液压泵，燃气管道内在外壳上焊接一液体管道且液体管道与液压泵连通，因此管道气泄漏的问题得以解决，安全性提高。管道外设置液压马达，将液压泵的液体压力转换成马达输出轴的机械能，液压马达的动能可带动发电机，风机，水泵等，而且将机组设置于燃气管道外，安装方便，成本降低。作为一种特别应用，液压马达带动风机，风机鼓动的空气与减压后的燃气进行逆流式热交换，对减压后的燃气进行加温，有利于燃气的传输。
本文所描述的概念在不偏离其精神和特性的情况下可以实施成其它形式。所公开的具体实施例应被视为例示性而不是限制性的。因此，本发明的范围是由所附的权利要求，而不是根据之前的这些描述进行确定。在权利要求的字面意义及等同范围内的任何改变都应属于这些权利要求的范围。
