Description

阀门位置转换器
技术领域
本申请涉及一种阀门位置转换器。
背景技术
旋塞阀门通常用于控制在管道和其他流容纳结构中流体的流动，诸如烃类流体。一些旋塞阀门包括在阀座配置和复位配置中的滑套和密封件。滑套被安装到中心旋塞上。当阀门关闭时，滑套和密封件操作以阻碍在进口和出口端口处通过阀门的流体流动。此双重密封作用有利地允许在阀门关闭时阀体的渗出。
当阀门打开时，滑套密封件完全从通过阀门的流体流动移除。当阀门从打开位置转换到关闭位置时，旋塞和附接滑套首先旋转90°。在整个旋转中维持滑套与阀体之间的间隙以减小驱动扭矩并且防止密封磨损。当滑套与进口和出口端口径向对准时，旋塞被降低，从而迫使滑套抵靠着阀体并且密封进口和出口端口。
当阀门从关闭位置转换到打开位置时，上述次序颠倒。首先，旋塞被升高，从而使滑套从阀体中缩回。其后，旋塞和滑套旋转90°以使通过旋塞的流动通道与进口和出口端口对准。因此，旋塞的线性和旋转运动都需要用来打开或关闭阀门。
旋塞阀门装配可以包括切换单元，所述切换单元监视阀门位置并且提供视觉阀门位置指示和/或阀门位置的电信号指示以控制和/或监视以通信方式耦合到切换单元上的装置。
发明内容
本文揭示了用于准确确定阀门是完全打开还是关闭的设备。在一个实施例中，阀门位置转换器包括凸轮管和杆。凸轮管具有圆柱形壁。壁中的第一槽沿着管子的径向弧而设置。壁中的第二槽从第一槽的末端并与第一槽成锐角延伸。杆贯穿壁，并且使凸轮管在第二槽中沿着凸轮管线性移动并且在第一槽中进行弧移动时旋转。
在另一实施例中，阀门装配包括阀门、阀门位置转换器，以及阀门位置指示器。阀门包括线性并且旋转移动以打开和关闭阀门的旋塞。阀门位置转换器安装到阀门上。阀门位置指示器安装到阀门位置转换器上。阀门位置指示器可以旋转来表示基于提供到阀门位置指示器的旋转运动的阀门的位置。阀门位置转换器组合旋塞的线性和旋转运动以产生指示阀门完全打开或关闭的旋转运动,并且将产生的旋转运动提供给阀门位置指示器。
在另一实施例中，阀门运动转换器包括设置在凸轮管中的杆。管子的第一引导特征经设置以将杆的线性运动转换成管子的旋转运动。管子的第二引导特征以一定角度从第一引导特征延伸。第二引导特征经设置以将杆的旋转运动转移到管子上。

符号和命名法：
在以下整个描述和权利要求书中,特定的术语被用来指代特定的系统组件。如所属领域的技术人员将理解，各公司可以利用不同的名称来指代组件。此文档并不意欲区分开在名称不同但并非功能上不同的组件。在以下论述中并且在权利要求书中，术语“包括”以及“包含”以一种开放式方式使用，并且因此应理解为意指“包括但不限于…”。此外，术语“耦合”意指间接或直接连接。因此，如果第一装置耦合到第二装置，那么该连接可能通过直接连接，或通过经过其他装置和连接件的间接连接。
具体实施方式
以下论述针对本发明的各实施例。尽管这些实施例中的一者或多者可以是优选的，但所揭示的实施例不应被理解为，或其他方式限制包括权利要求书的本发明的范围。此外，所属领域的技术人员将理解，以下描述具有广泛的应用，并且任何实施例的论述仅意指该实施例的示例性描述，且并不表示包括权利要求书的本发明的范围限于该实施例。
线性和旋转运动都可能需要用来打开或关闭阀门。不幸的是，耦合到阀门上的切换单元仅可以响应于旋塞旋转，而非同时响应旋塞的线性和旋转运动两者。因此，当同时需要线性和旋转旋塞运动时，此类切换单元不能准确确定阀门是完全打开还是关闭。
出于各种原因，准确确定阀门是完全打开还是关闭是非常重要的。例如，流量校准的执行要求阀门完全关闭。否则，通过阀门的流量会令校准不可靠，因而得出不准确的流体流量测量。
本发明的实施例并入阀门位置转换器，所述转换器允许通过切换单元顾及线性和旋转旋塞运动两者，所述切换单元经配置以仅基于旋塞旋转运动确定阀门位置。因此，使用此类切换单元使各实施例能准确确定阀门位置。
图1示出了根据各实施例而包括阀门位置转换器102的阀门装配100。阀门装配100还包括阀门104、阀门操纵器106，以及切换单元（阀门位置指示器）108。阀门104包括阀体110和旋塞120。在图1中，阀体110的各部分和操纵器106被切开以示出内部特征。阀体110包括进口和出口端口112。旋塞120包括通道118，当端口112与通道118对准时，流体通过所述通道118在进口与出口端口112之间穿过。滑套114固定到旋塞120的相对侧面上。密封件116紧固到每一个滑套114上。滑套114通过密封进口和出口端口112来关闭阀门。
操纵器106耦合到阀体104上并且控制旋塞120的移动。图1中示出的操纵器106的实施例包括手轮122。手轮122转动与轴126啮合的在操纵器106中的齿轮以在阀门104打开或关闭时使旋塞120旋转、升高，及降低。操纵器106的其他实施例可以提供除了手轮122之外的构件以驱动操纵器106，例如，电动马达、液压马达等。
轴124从操纵器106延伸。轴124对应于旋塞120的移动而旋转、延伸，或缩回。因此，轴124的移动反映了旋塞120的移动。当操纵器106使旋塞120旋转时，轴124在与旋塞相同的弧线上旋转。当操纵器垂直移动旋塞120，轴124垂直地位移等价于旋塞120垂直移动的数量。
阀门位置转换器102耦合到操纵器106上。轴124以其旋转和线性运动的形式将旋塞运动输入提供给阀门位置转换器102。阀门位置转换器102还耦合到切换单元108上。在一些实施例中，切换单元108可以为由套普沃克斯（TOPWORX）公司制造的阀门顶部（VALVETOP）旋转位置监视器，或其他阀门位置指示器。阀门位置转换器102将轴124的线性运动转换成驱动切换单元108的旋转运动，并且将轴124的旋转运动的至少一部分转移到切换单元108中。阀门位置转换器102经配置以将旋转弧提供给切换单元108，所述旋转弧对切换单元108指示在打开与关闭的阀门位置之间的完全转换。阀门位置转换器基于轴124的总组合线性和旋转位移产生此旋转弧。因此，仅当轴124（和旋塞120）已经被完全线性并且旋转位移时，阀门位置转换器102才提供旋转以指示在阀门104的打开与关闭位置之间的完全转换。例如，如果切换单元108的输入处需要90°的旋转来指示在阀门104的打开与关闭位置之间的完全转换，那么只有在轴124旋转90°并且轴124被操纵器106完全延伸或缩回（根据打开或关闭的阀门位置所需）时，阀门位置转换器102才会将90°的旋转提供给切换单元108。
图2示出了根据各实施例的阀门位置转换器102的爆炸视图。阀门位置转换器102包括安装托架，所述安装托架包括下部部分202和上部部分204。安装托架的下部部分202通过螺栓或其他附接构件附接到操纵器106上。下部部分202中的开口216使轴124穿过安装托架。安装托架的上部部分204通过螺栓或其他附接构件附接到下部部分202上。
连接器206借助于固定螺钉或其他附接装置紧固到轴124上。穿过连接器206的通道232所形成的尺寸足以将从通道232延伸的杆208固持在连接器206的相对侧面上。杆208可以通过固定螺钉或所述领域公知的其他附接装置紧固在连接器206中。
连接器206设置在凸轮管210的孔径内。连接器206和凸轮管210的孔径所形成的尺寸，足以使连接器206响应于轴124的旋转和线性位移在凸轮管210的孔径内旋转并且纵向移动。
凸轮管210包括一组槽，从连接器206延伸的杆208的端设置在所述槽内。第一槽220沿着凸轮管210的径向弧设置。第二槽222与第一槽220成锐角而设置。第一槽220和第二槽222在每一个槽的一个端处相交。
位置指示器适配器212通过安装托架的上部部分204中的通道224延伸。适配器212的一个部分226形成所需尺寸以安装在凸轮管210的孔径内。适配器212可以通过焊接或所述领域中已知的其他附接方法紧固到凸轮管210上。适配器212的凸缘230通过固定板214固定在安装托架的上部部分204的埋头孔228内。固定板214通过螺栓或其他附接装置紧固到安装托架的上部部分204上。适配器212在通道224和埋头孔228内自由旋转。
现在参考图3A到3C，概述了阀门位置转换器102的操作。当阀门104完全关闭时，杆208定位在位置302处（也即，第二槽222的底部），如图3A中所示。当阀门104开始打开，旋塞120在阀体110内升高，从而导致轴124从操纵器106线性延伸。当杆208在凸轮管210内朝上移动，杆208维持其侧向位置并且凸轮管210逆时针旋转（当从凸轮管210的顶部观察）。当轴124完全延伸时，杆208定位在位置304处（也即，槽220与222的交点），如图3B中所示，并且凸轮管210已经逆时针旋转了一定的量，所述量由槽222的斜率确定。在凸轮管210的一些实施例中，配置槽222从而轴124从位置302到位置304的线性运动使得凸轮管210旋转约45°。在其他实施例中，轴124的线性位移可以引起不同量的凸轮管旋转。
当旋塞120已经完全升高（也即，轴124完全延伸）时，操纵器106开始使旋塞120旋转。在阀门打开期间，旋塞120和轴124沿逆时针方向旋转。当杆208在槽220中侧向移动时，凸轮管210保持静止，直到杆208在位置306处与槽220的端啮合，如图3C中所示。在一些实施例中，槽220的长度等价于由槽222导致的旋转弧。
在杆208与槽220的端啮合之后，在整个剩余的部分旋塞/轴旋转中，凸轮管210与轴124一起旋转。因此，凸轮管210将轴124的旋转运动的终端部分转移到切换单元108，而轴旋转运动的初始部分被忽视。在凸轮管210的一些实施例中，轴124的旋转仅在终端的45°的轴（旋塞）旋转期间被转移到切换单元108中。通过轴124的线性和旋转移动所产生的总的凸轮管旋转，等价于旋转弧，切换单元108需要所述旋转弧来视为阀门完全打开。
当阀门104从完全打开转换到完全关闭位置时，上述操作的顺序基本上颠倒。当阀门104完全打开时，杆208在位置306处定位在槽220的端处。操纵器106通过使旋塞120沿顺时针方向旋转启动阀门104的关闭。当轴124沿顺时针方向旋转，从而在槽220中侧向移动杆208时，凸轮管210保持静止直到杆208达到槽220与222的交点。当杆208达到槽220与222的交点时，在轴旋转的剩余部分中，凸轮管208沿顺时针方向旋转。
当操纵器106已经完全使旋塞120旋转到与进口和出口端口112对准时，操纵器106降低旋塞120以将滑套114移动到密封位置中。当旋塞120降低时，轴124缩回到操纵器106中，从而导致凸轮管210在杆208从位置304移动到位置302时沿顺时针方向旋转。因此，凸轮管210在轴124的旋转的终端部分中并且在轴124的线性缩回中旋转。通过轴124的线性和旋转移动而产生的总的凸轮管旋转等价于旋转弧，切换单元108需要所述旋转弧来认为阀门完全关闭。
图4A到4C示出了根据各实施例的阀门位置转换器102的凸轮管210和适配器212的视图。图4A示出了经接合的凸轮管210和适配器212的前视图。凸轮管210和适配器212包括对准件402，所述对准件指定了用于接合的管210和适配器212的相对定向。图4A还示出了在凸轮管210的相对侧面上的槽220和222。杆208在凸轮管210的两个侧面上通过槽220、222延伸。
图4B示出了经接合的凸轮管210和适配器212的横截面图。在凸轮管210的背部中的槽220、222被示出。适配器212包括空腔404以固持切换单元108的配合部。空腔404的底部包括凹槽406或其他特征，通过所述特征，旋转从适配器212转移到切换单元108中。根据NAMUR标准，空腔404和凹槽406形成所需尺寸以接收由切换单元108提供的轴。适配器212的其他实施例可以支持不同的耦合标准或布置。图4C示出了包括空腔404和凹槽406的适配器212的俯视图。还示出了凹槽相对于对准件402以及槽220、222的定向。
上述论述意指说明本发明的各实施例的原理。对于所属领域的技术人员，一旦完全了解上述揭示，许多变体和修改将变得显而易见。例如，尽管各实施例在本文中描述为包括使杆208穿过凸轮管210的壁的槽，但在一些实施例中，槽可能为凹槽或凸轮管壁中的其他引导特征，并且杆208设置在该引导特征中。此外，所属领域的技术人员将理解，各实施例涵盖线性和旋转旋塞运动的不同次序、不同量的线性位移到旋转的转换，以及将各种量的旋转提供到切换单元中。以下权利要求书旨在解释以包涵所有此类变体和修改。
