Description

带有支杆的蝶阀
背景技术
本文公开的主题涉及阀。更具体地,本文公开的主题涉及带有气动致动的蝶阀。
典型的蝶阀由气动致动器控制。致动器包括定位在活塞缸内的活塞。活塞连接到联动组件,该联动组件将活塞在活塞缸内的线性运动转换成轴的旋转运动。该轴进而连接到定位在阀体或其它流动结构中的蝶盘。轴的旋转通过联动组件使蝶盘在阀体内旋转,因此打开或关闭该阀。
在典型的蝶阀中,阀体被连接到气动致动器的致动器本体,致动器中心轴线和阀体中心轴线被布置成共面并且在一些情况下彼此平行。在这种构造中,致动器实际上是从阀体悬臂伸出。如此,致动器在操作中易受振动的影响。致动器能出现振动幅值,这些振动幅值足够高以导致联动系统的约束、损坏或故障并且进而导致蝶阀的故障。
发明内容
在一个实施例中,蝶阀包括具有阀体中心轴线的阀体。阀致动器被可操作地连接到阀体。阀致动器被定位成使得阀致动器的中心轴线与阀体中心轴线不平行。支杆从阀体延伸到致动器壳体从而以与阀体成固定关系地支撑阀致动器。
在另一实施例中,气动致动的蝶阀包括具有阀体中心轴线的阀体和可旋转地定位在阀体内的阀盘。气动致动器被定位成使得气动致动器的中心轴线与阀体中心轴线不平行。致动器包括设置在活塞缸内的活塞,活塞可操作地连接到阀盘。支杆从阀体延伸到致动器壳体从而以与阀体成固定关系地支撑致动器。
这些和其它优点和特征将从下面的结合附图理解的描述而变得更加容易理解。
附图说明
在说明书的结论部分处的权利要求中具体指出并清楚地要求保护了作为本发明的主题。结合附图理解下面的具体描述,能够容易理解本发明的前述的和其它的特征和优点,附图中:
图1是气动致动的蝶阀系统的实施例的截面图;
图2是气动致动的蝶阀系统的实施例的透视图;
图3是蝶阀系统的从阀体延伸到致动器壳体的支杆的透视图;以及
图4是到阀体的支杆附接的另一透视图。
通过参照附图的示例,具体描述解释了本发明的实施例,以及优点和特征。
具体实施方式
图1中示出的是气动操作的蝶阀10的实施例,例如那些用于调节气动控制设备(未示出)的空气流的蝶阀。阀体14延伸穿过流动路径16,阀盘18可旋转地定位在阀体14内,使得阀盘18的旋转减少或增加可允许通过流动路径16的流动。阀盘18被连接到气动致动器20,其驱动阀盘18的旋转。气动致动器20包括致动器壳体22,致动器壳体22在其内具有活塞缸24,并且活塞缸24内可滑动地设置有活塞26。活塞26由轴28通过联动组件51连接到阀盘18,以将活塞26在活塞缸24内的响应于活塞缸24内的气动压力变化的滑动运动转换成阀盘18的旋转运动。
现在参照图2-4,气动致动器20被固定到阀体14以增加气动致动器20的固有频率,由此减少气动致动器20对振动和位移的易受影响性,振动和位移引起联动系统51的故障和/或损坏。参照图2,气动致动器20被相对阀体14定位成使得中心致动器轴线30与中心阀体轴线32不平行。在一些实施例中,如在图2中所示,中心致动器轴线30基本上垂直于(成九十度角)中心阀体轴线32。应该意识到的是,轴线30和32可以其它的角度被布置,使得轴线30和32不平行,例如45度或60度。
除了被固定到附接凸台50以外,为了给气动致动器20提供支撑并防止振动移动,致动器支撑支杆34在阀体14和致动器壳体22之间延伸以连接这两个部件。虽然在图2中示出了一个支撑支杆34,但是应该意识到的是,也可以利用两个或更多的支撑支杆34。在图2的实施例中,支撑支杆34是Y形的,底部36被固定到阀体14而两个臂38(图3)从底部36延伸并被固定到致动器壳体22。在一些实施例中,臂38(图3)在臂38(图3)和致动器壳体22的切点处被固定到致动器壳体22,以增加所提供的支撑总量。臂38(图3)通过螺栓40被固定到致动器壳体22,或者替换地通过其它合适的装置。
现在参照图3和4,支撑支杆34的底部36例如通过螺栓40被固定到阀体14。如所示,在一个实施例中,阀体14和底部36通过两个螺栓40连接。利用两个螺栓40来将底部36固定到阀体14增强了对由气动致动器20的操作所引起的力矩和摇摆运动的阻力。在一些实施例中,底部36被固定到从阀体14的引导体44向外径向延伸的阀体凸缘42。
相对于阀体14(如至少在图2中所示)旋转气动致动器20(图2)并将阀体14通过支撑支杆34固定到致动器壳体22已经被示出为使组件的固有频率增加了一倍。增加的固有频率导致了对振动输入的更低的放大以及气动致动器20(图2)相对于阀体14的减小的位移。减小的相对位移导致了在蝶阀10(图1)的部件上的更低的应力并改善了蝶阀的可靠性和寿命。
虽然仅参照有限数量的实施例具体描述了本发明,但应该容易理解的是本发明并不限于这种所公开的实施例。更确切地说,本发明可被改进以包含任意数量的变型、改变、替换、或等同布置,这些内容虽然目前未被描述,但是与本发明的精神和范围相称。另外,虽然已经描述了本发明的各种实施例,但应该理解的是,本发明的各方面可仅包括所描述实施例中的一些。因此,本发明不应被视为受前面的描述所限制,而是仅由所附权利要求的范围限制。
