斜轴变孔径球阀
技术领域
本发明属于流体控制阀技术领域,涉及一种斜轴变孔径球阀。
背景技术
在化工行业中使用的放料阀采用普通“O”型直通球阀较为普遍,其球体不能直接紧贴反应釜底面,反应釜底面与球体之间有一段管状通道,容易造成积料,使物料不能完成混合,进而影响反应物质量;有时因温度过低料液会结晶,影响正常放料,给操作和生产带来了很大的不便;当需要调节流量时,普通放料球阀无法实现调节功能。所以,如何解决物料堆积死角、物料低温结晶阀门卡死以及流量可调成为用户普遍关心的问题。
发明内容
本发明针对上述问题,提供一种斜轴变孔径球阀,该球阀结构紧凑、无积料、密封性能好、使用寿命长、无死角、可调节流量且可剪切物料。
按照本发明的技术方案:一种斜轴变孔径球阀,其特征在于:包括阀体,阀体的侧法兰上安装上法兰,上法兰上安装反应釜,阀体内腔中及上法兰的下端分别设置阀座,各个阀座围拢形成的空间设置球体,球体上下两端分别设置一个V型缺口,球体侧部与阀杆扁方连接,阀杆的台阶面上依次套设止推垫、轴承,轴承及止推垫置于阀体的颈部;阀体的填料函中依次装入填料、填料压套,填料压套通过填料压盖压紧固定;阀体的中法兰上固定连接支架,阀杆通过连接轴与气动执行器相连,气动执行器通过第二螺栓固定在支架的法兰上,气动执行器上安装有定位器。
作为本发明的进一步改进,所述上法兰通过开槽沉头螺钉与阀体紧固连接,所述反应釜、上法兰及阀体侧法兰通过第一螺栓、第一螺母紧固连接。
作为本发明的进一步改进,所述填料压盖通过第二螺柱及第二螺母锁紧固定。
作为本发明的进一步改进,所述支架通过第一螺栓紧固连接于阀体中法兰上,气动执行器通过第二螺栓与支架固定连接。
作为本发明的进一步改进,所述上法兰的圆弧形凹槽与反应釜内壁具有相同的同心球半径R。
作为本发明的进一步改进,所述球体在关闭位置时,球体轮廓边缘与反应釜釜底留有一段微小距离δ。
作为本发明的进一步改进,阀体颈部中心与流道中心倾斜成α角,所述的球体扁方连接处与球体通道倾斜成α角。
作为本发明的进一步改进,所述球体球面进出口开V型缺口,V型缺口中心线与球体通道倾斜成β角。
本发明的技术效果在于:1、本发明的球体几乎直接紧贴反应釜底面,不会在阀门进口处积料成死角。
2、本发明的阀杆及气动执行器与阀体流道中心倾斜成α角,不会因反应釜与气动执行器空间干涉而导致阀门无法安装。
3、本发明的球体球面上的V型缺口与阀座之间可形成有效的剪切作用,不会因反应釜釜底物料结晶而打不开阀门。
4、本发明的球体球面上的V型缺口可以通过定位器定量调节反应釜内的物料流量。

具体实施方式
下面结合附图对本发明的具体实施方式作进一步的说明。
如图1~5所示,本发明一种斜轴变孔径球阀,包括阀体7,阀体7的侧法兰上安装上法兰1,上法兰1上安装反应釜23,阀体7内腔中及上法兰1的下端分别设置阀座6,各个阀座6围拢形成的空间设置球体8,球体8上下两端分别设置一个V型缺口,球体8侧部与阀杆9扁方连接,阀杆9的台阶面上依次套设止推垫10、轴承11,轴承11及止推垫10置于阀体7的颈部;阀体7的填料函中依次装入填料12、填料压套13,填料压套13通过填料压盖15压紧固定;阀体7的中法兰上固定连接支架19,阀杆9通过连接轴18与气动执行器21相连,气动执行器21通过第二螺栓20固定在支架19的法兰上,气动执行器21上安装有定位器22。
上法兰1通过开槽沉头螺钉5与阀体7紧固连接,所述反应釜23、上法兰1及阀体7侧法兰通过第一螺栓3、第一螺母4紧固连接。
填料压盖15通过第二螺柱16及第二螺母17锁紧固定。
支架19通过第一螺栓14紧固连接于阀体7中法兰上,气动执行器21通过第二螺栓20与支架19固定连接。
上法兰1的圆弧形凹槽与反应釜23内壁具有相同的同心球半径R。
球体8在关闭位置时,球体8轮廓边缘与反应釜23釜底留有一段微小距离δ。
阀体7颈部中心与流道中心倾斜成α角,所述的球体8扁方连接处与球体8通道倾斜成α角。
球体8球面进出口开V型缺口,V型缺口中心线与球体8通道倾斜成β角。
本发明的工作原理如下:本发明的球体8几乎直接紧贴反应釜23底面,不会在阀门进口处积料成死角;本发明的阀杆9及气动执行器21与阀体7流道中心倾斜成α角,不会因反应釜23与气动执行器21空间干涉而导致阀门无法安装;本发明的阀杆9下部通过扁方与球体8榫槽连接,上部通过连接轴18与气动执行器21相连,定位器22安装在气动执行器21顶部。通过调节定位器22来控制阀门的开度以获得不同的流量需求。
当开启阀门时,球体8球面上的V型缺口与阀座6之间可以对物料进行有效的剪切,防止物料结晶使阀门无法正常开关。当关闭阀门时,由于球体8是浮动结构,物料将球体8推向下游阀座6,使阀门密封更加可靠。
