Description
本发明涉及一种多路阀,属于石油、化工等油气集输***领域。
多路阀是原油开采设备中的重要部件,多路阀上具有多个油口(或称为来液口),多个油口均连接有用于输送油液的管线(包括计量管线、来液管线以及集输管线)。申请号为201520080459.7的中国专利提供了一种多路阀,该多路阀的上阀体沿其周向布置有多个油口,对应的计量管线和来液管线需要沿上阀体的周向布置以便与油口连接。然而,计量管线和更多的来液管线这种周向布置的方式使得多路阀的平面空间占用较大,管线布置比较繁琐;而且还会使得阀体腔承压空间增大,意味着阀体壁厚增大,阀体总重量增加,这些都是不利的因素。
为解决上述问题,公开号为CN107191627A的中国专利公开了一种多路阀,该多路阀的左右两个阀体相对布局的结构,使多路阀由原来单一平面变成空间两个平面,实现了层间空间布局,使连接的单井数双倍于现有单层多路阀的单井数量,也就是说,若利用该专利所公开的多路阀连接与现有技术中的多路阀相同数量的管线,该专利的多路阀具有所占空间更小、重量更轻的优点。
然而,该专利所公开的多路阀却存在以下缺陷:
上述的多路阀仅设置一个阀芯,多路阀的多个来液口仅通过一个阀芯控制来与多路阀的计量口选择性地连通,当来液口数量增多时,由于来液口周向布置,使得多个来液口所在圆的直径增大,而该多个来液口通常形成在竖直的平面上,使得整个多路阀在竖直方向上的尺寸增大,这势必增大多路阀在竖直方向上所占用的空间。

为使本领域技术人员更好的理解本发明的技术方案,下面结合附图和具体实施方式对本发明作详细说明。
如图1和图2所示,本发明实施例公开的一种多路阀,该多路阀用于连接输送油液的管线。该多路阀包括阀体10以及两个阀芯。阀体10内部形成有阀腔14,且阀体10具有计量口16、集输口17以及多个来液口15,来液口15和集输口17均与阀体10内的阀腔14贯通。其中,计量口16用于测量油液的流量,集输口17用于汇集从来液口15进入阀腔14内的油液。两个阀芯均伸入至阀腔14中,其中,使多个来液口15分成两组,两组来液口15均分别周向布置,两个阀芯分别对应控制两组来液口15,也就是,其中一个阀芯通过转动选择性地使对应的一组来液口15中的任意一个来液口15与计量口16连通;另一个阀芯通过转动选择性地使对应的另一组来液口中的任意一个来液口15与计量口16连通。
容易理解:每组周向布置的来液口15所确定的圆的圆心位于所对应的阀芯的转动中心线上。
本发明使来液口分成周向布置的两组并分别利用两个阀芯控制来液口15与计量口16通断的优点在于:
1、多个来液口15分成周向布置的两组相比于只通过一组进行周向布置,所分成的两组的每组所在的圆的直径减小,当每组来液口15所确定的平面为竖直平面时,可减小阀体10在竖直方向上的尺寸,从而能够在连接相同数量管线条件下,使得多路阀所占用的竖直空间较小(或者说多路阀的厚度尺寸较小)。
2、可通过转动其中任意一个阀芯使得所有来液口15中的任意一个来液口15与计量口16导通,从而能够测量经过该来液口15的油液的流量。
3、通过两个阀芯控制来液口15与计量口16的通断,使得测量油液流量的方式更加灵活。
4、通过两个阀芯控制来液口,使得阀体连接的单井数量成倍增加,在高压大尺寸要求多井的有限空间中应用,其更具有优越性。
5、方便布置阀芯,使得两个阀芯在各自分别通过转动而使来液口15与计量口16连通时不会发生干涉现象。
在本发明中,两个阀芯的布置方式可以有多种,例如,可以使其中一个阀芯从阀体10的左侧伸入至阀腔14中,其中另一个阀芯从阀体10的上端伸入至阀腔14中;再例如,可以使其中一个阀芯从阀体10的右侧伸入至阀腔14中,其中另一个阀芯从阀体10的上端伸入至阀芯中;再例如,可使两个阀芯同时从阀体10的上端、左侧、右侧以及下端同时伸入至阀腔14中。
在本发明的一个优选实施例中,两个阀芯的布置方式为:使两个阀芯分别从阀体10的左、右两侧伸入至阀腔14中,对应地,使阀腔14形成两个左、右相对的腔壁,且两个来液口15分别形成在两个腔壁上,并分别绕对应的阀芯周向布置,两个阀芯通过转动分别控制两个腔壁上的两组来液口15与计量口16的通断。在本实施例中,两个阀芯与两组来液口15的控制的对应关系可以有两种:一种是使从左侧伸入阀腔14中的阀芯用于控制右腔壁上的一组来液口15与计量口16的通断,使从右侧伸入至阀腔14中的阀芯用于控制左腔壁上的一组来液口15与计量口16的通断;另一种是使从左侧伸入阀腔14中的阀芯用于控制左腔壁上的一组来液口15与计量口16的通断,使从右侧伸入至阀腔14中的阀芯用于控制右腔壁上的一组来液口15与计量口16的通断(附图1所展示的是该种情况)。在本实施例中,两个阀芯同轴设置(当然,两个也可以不同轴)。
上述的阀芯可通过多种方式控制两组来液口15与集输口17的通断,例如,阀芯伸入阀腔14的部分通过封堵的方式只允许一个来液口15与阀腔14连通,从而油液经过未封堵的来液口15进入阀腔14,然后再进入集输口17。
在本发明的一个优选实施例中,利用开设在阀芯上的通道,使得每组来液通道中的一个来液口15与计量口16连通,而经过其余来液口15的油液进入阀腔14后由集输通道汇集,并进入集输管线。具体地,阀芯位于阀腔14内的部分形成有导液通道23,导液通道23的两端分别为对接端231和选通端232;两个导液通道23的对接端231均分别与计量口16对接,两个导液通道23的选通端232用于与来液口15选择性地对接而连通。如此,当需要计量经过某一来液口15的油液的流量时,通过转动阀芯而使导液通道23的选通端232与该来液口15对接,对接端231与计量口16对接,从而使来液 口15与计量口16导通,经过其余来液口15的油液进入阀腔14后由集输口17汇集然后进入集输管线。
应该理解:在阀芯转动过程中,对接端231与计量口16需始终处于对接状态,为能够达到对接端231与计量口16需始终处于对接状态的目的,可使对接端231处的阀芯设置形成插套,对接端231形成在插套的端部,且使插套的轴线与阀芯的转动轴线同轴,并使插套***计量口16中,如此,当阀芯转动时,插套绕自身的轴线转动而不会整体相对计量口16发生线性运动,从而使对接端231与计量口16始终处于对接状态。当然,使对接端231与计量口16需始终处于对接状态的结构和方式还有多种,在此不再一一赘述。
为方便制造、装配和维修,阀体10设置成分体结构,具体地,如图1和图6所示,本实施例的阀体10包括左阀体11、右阀体12以及中阀体13,左阀体11、右阀体12以可拆卸的方式装设于中阀体13的两侧,左阀体11、中阀体13以及右阀体12共同围成阀腔14。其中,两组来液口15分别开设在左阀体11和右阀体12上;两个阀芯分别为左阀芯21和右阀芯22,左阀芯21穿过左阀体11后伸入至阀腔14中,右阀芯22穿过右阀体12伸入至阀腔14中,且左阀芯21用于控制开设在左阀体11上的来液口15与计量口16的通断,右阀体12用于控制开设在右阀体12上的来液口15与计量口16的通断。优选地,计量口16伸入至阀腔14中并形成朝向相反的两个端口;左阀芯21上的左导液通道的左对接端与计量口16朝向左阀体11的端口对接,右阀芯22上的右导液通道的右对接端与计量口16朝向右阀体12的端口对接。
为方便安装用于驱动阀芯转动的外部动力机构(例如,驱动电机)并同时为提高阀芯的刚度(阀芯因伸出阀体外一段而会使得自身刚度减小),在本发明的一个优选实施例中,如图1和图2,并结合图6和图7所示,在左阀体11和右阀体12的外侧均架设法兰盘30,左阀芯21位于左阀体11外的部分以及右阀芯22位于右阀体12外的部分分别穿设两个法兰盘30。如此,两个外部动力机构可通过紧固件分别固定在两个法兰盘30上,阀芯穿设法兰盘30与外部动力机构的输出轴连接,外部动力机构提供扭力以驱动阀芯转动,从而使导液通道23的选通端232与来液口15选择性对接。在本实施例中,阀芯穿设法兰盘30的一段上形成有轴肩;轴肩处装设有推力轴承33;推力 轴承33由套设于阀芯上的顶盖32的头部推抵以使推力轴承33与轴肩紧抵,顶盖32的尾部与法兰盘30形成有调整间隙。
本发明在阀体10外架设法兰盘30的优势在于:一方面,外部动力机构可直接通过法兰盘30安装在阀体10上,从而方便外部动力机构快速装配于多路阀上;阀芯穿设法兰盘并由推力轴承支撑,从而提高了阀芯的刚度;再一方面,将具有支撑及承载的推力轴承布局到阀体外,从而减少了装设于阀体中的轴承的数量,使阀体内无复杂的运动结构,便于维护,运行无故障周期延长。
优选地,在法兰盘30上还通过紧固件装设有过渡盘31,外部动力机构通过紧固件装设于过渡盘31上。
为能够保证在阀芯转动时,导液通道23的对接端231与计量口16的端口始终保持对接状态,并尽量减小计量口16对阀芯转动的阻力,在本发明的一个优选实施例中,计量口16的两个端口内分别装设滑动轴承40,导液通道23的对接端231伸入至滑动轴承40中,且滑动轴承40与对接端231之间设置有密封圈以防止油液从对接端231与端口之间流出。如此,密封圈有效防止了对接处漏油,滑动轴承40能够保持阀芯转动更加顺利。
本发明所提供的多路阀在多处位置需要密封设置:
1、在阀芯穿设阀体10的位置需要密封。
具体地,如图1和图4所示,左阀体11和右阀体12分别对应开设有左安装孔和右安装孔,左阀芯21穿设左安装孔以伸入至阀腔14中,右阀芯22穿设右安装孔以伸入至阀腔14中;左阀芯21与左安装孔之间以及右阀芯22与右安装孔之间均装设有密封组件;密封组件包括外套52、内套51以及密封填料53;外套52的第一端设置有挡环,内套51的第一端自外套52的第二端伸入至外套52中;密封填料53设置于挡环与内套51的第二端之间。密封组件的装配方式为:使两个安装孔(左安装孔和右安装孔)分别对应于两个阀芯(左阀芯21和右阀芯22)之间均形成环状空隙,使密封组件中的外套52和内套51的第一端自阀体10外伸入至环状空隙中,并使外套52的外壁与安装孔的孔壁贴合,使内套51的内孔壁以及密封填料53包覆阀芯,从而实现阀芯与阀体10之间的密封。在本实施例中,密封组件为装配式组件,密封组件可在阀体10外完成自身的整体装配,如此,当处于使用状态的密封 组件中的密封填料在即将失效时,可通过整体更换密封组件来节约更换的时间,提高了更换效率,降低了设备的维护成本。
2、导流通道的选通端232与来液口15的对接处需要密封。
具体地,如图1和图5所示,在左导液通道的左选通端和右导液通道的右选通端分别设置有阀座环61,阀座环61内侧的导液通道23的内壁上形成环形的第一台阶面,阀座环61与第一台阶面之间设置内六方螺母64,其外周开设有外螺纹,内六方螺母64包括外径不等的圆柱状的两部分,外径较大的一端抵在第一台阶面上,外径较小的一端朝向阀座环61,外径较小的圆柱状部分外套设有在内六方螺母64的作用下变形产生轴向力的弹簧63,弹簧63与阀座环61之间设置在弹簧63的作用下顶推阀座环61的推力环62,弹簧63可以选用波形或碟形弹簧63,推力环62和弹簧63的设置,使得阀座环61一直保持紧密的贴合来液口15,实现了结合密封。同时,阀座环61与导液通道23之间设置密封圈,用于密封阀座环61与导液通道23。
以上实施例仅为本发明的示例性实施例,不用于限制本发明,本发明的保护范围由权利要求书限定。本领域技术人员可以在本发明的实质和保护范围内,对本发明做出各种修改或等同替换,这种修改或等同替换也应视为落在本发明的保护范围内。
