Description

塞体轴向移动调节开闭动作相位调节流量的旋塞阀 技术领域
本发明涉及旋塞阀技术领域，是一种塞体采用异形通孔，塞体可轴向右移或左移，在塞体匀速转动时可以调节开闭动作相位，在流体压差不变条件下可以调节流体流量的旋塞阀。
背景技术
旋塞阀是通过旋转使塞体上的通道口与阀体上的通道口相同或分开，实现开启或关闭的一种阀门。旋塞阀广泛地应用于油田开采、输送和精练设备中，广泛用于工业中。
旋塞阀是用带通孔的塞体作为开闭件的阀门。塞体随阀杆转动，以实现开闭动作。旋塞阀的重要特性是它易于适应多通道结构，一个阀可以获得一个或多个不同的流道。可以简化管道系统的设计、减少阀门用量及连接配件。
传统旋塞阀由阀体、塞体、带阀杆的手动柄组成，塞体为圆柱体，径向开通孔，阀体为圆管状，径向对开通孔，阀体与塞体密切接触，手动柄在90度范围内往复转动，通过阀杆带动塞体转动，改变塞体通孔相位，塞体通孔与阀体通孔形成开闭件。参见图8。缺点是，在往复转动中，开启点、关闭点、开程相位不能改变。
传统旋塞阀开闭动作的过程参见图9，D-D剖面的塞体相位连续变化图，图9中自左向右依次为第一相位1，第二相位2，第三相位3，第四相位4和第五相位5。从第一相位阀门全关闭开始，塞体顺时针转动30度变为第二相位，阀门开启点。塞体再顺时针转动60度变为第三相位，阀门全开启。然后塞体逆时针转动60度变为第四相位，阀门关闭点。塞体再逆时针转动30度变为第五相位，同第一相位，阀门全关闭。
对于传统旋塞阀，要想调节改变通过阀门的流体流量，有两种方法。一是在开闭周期内分时段改变塞体转速，延长塞体开启时段就可以让更多流体通过。二是改变流体压差，比如在流体上游设置增压装置，使流体上下游之间压差增大，在相同的开程相位内可以让更多流体通过阀门。这两种方法都需要复杂的变速或变压设备装置来支撑，有局限性。
需要一种塞体采用异形通孔、塞体可轴向右移或左移、在塞体匀速转动时可以调节开闭动作相位，在流体压差不变条件下可以调节流体流量的旋塞阀。
发明内容
本发明的目的是提供一种塞体采用异形通孔、塞体可轴向右移或左移、在塞体匀速转动时可以调节开闭动作相位，在流体压差不变条件下可以调节流体流量的旋塞阀。
塞体轴向移动调节开闭动作相位调节流量的旋塞阀，包括：动力盘、轴承、内花键、外花键、阀杆、拨环、拨叉、塞体、阀体。特征在于：塞体、阀杆、拨环、外花键为一体，与动力盘、内花键之间是花键连接。轴承与阀体固定。动力盘、内花键只能转动。塞体、阀杆、拨环、外花键在与动力盘同相转动时，也轴向右移或左移。
所述动力盘为圆盘，被动力源带动转动，左侧为圆柱体，支撑在轴承上，并连接内花键。动力盘在轴承支撑下转动，不轴向移动。
所述塞体为圆柱体，塞体沿轴向设置异形通孔，塞体异形通孔沿塞体径向设置。所述塞体异形通孔指该通孔在不同轴向位置段的圆周向尺寸不同，形状为左窄右宽。塞体通过阀杆与外花键连接，阀杆上设有拨环，拨环位于拨叉的卡槽中，拨环与拨叉采用相对低阻力设置，拨环在拨叉卡槽中转动。当拨叉沿轴向右移或左移时，带动拨环、阀杆、塞体和外花键沿轴向右移或左移。
所述花键连接为现有成熟机械，内花键与外花键可以相对轴向移动滑动，两者转速相同。所述阀杆为圆柱体，所述拨环为圆环体，与阀杆共轴连体。所述拨叉为U形卡槽，左右移动不转动。
所述阀体为圆管状体，阀体内壁与塞体外壁密切接触。阀体设置多组径向通孔，每组阀体通孔都对应相同轴向位置段的塞体异形通孔，形成控制流道开闭动作的开闭件。
本发明有两种结构形式。
本发明结构形式一。阀体沿轴向依次设置六组十二个阀体通孔，每组有一上一下、径向相对的两个阀体通孔。塞体从左到右设置六个塞体异形通孔，六个异形通孔的轴向位置分别对应六组阀体通孔的轴向位置，可以与阀体通孔配合形成六副开闭件，六个塞体异形通孔在阀门全开启时的塞 体相位根据实际需要相互错开相位设置。参见图2。
本发明结构形式一的动力盘在轴承支撑下受动力源带动转动，通过内花键带动外花键转动，因此塞体、阀杆、拨环与动力盘同相位转动。转动中，各塞体异形通孔与各阀体通孔配合形成的各开闭件具有不同的开启点、关闭点、开程的相位。当塞体转动时，控制拨叉轴向右移或左移，带动转动中的拨环、阀杆、塞体右移或左移。与阀体通孔配合形成开闭件的六个塞体异形通孔的轴向位置段和圆周向尺寸发生改变，六副开闭件的开启点、关闭点、开程的相位发生改变，由此调节相位，由此调节流体流量。结构形式一用于上下径向相通的多个流道调节开闭动作相位的开关控制。塞体转动一周，六个上下径向相通的流道各开闭两次。
以图2中左侧第一个塞体异形通孔与左侧第一副阀体通孔形成的第一副开闭件的塞体相位调节效果为例。在塞体匀速转动时拨叉轴向右移或左移所形成的开启点、关闭点、开程相位的两种相位调节效果参见图3与图5，下面是对比说明。
图3A-A剖面的塞体相位连续变化图中示意了连续变化的五种塞体相位，图中自左向右依次为第一相位1，第二相位2，第三相位3，第四相位4和第五相位5。当塞体匀速转动时，拨叉右移。从第一相位阀门全关闭状态开始，塞体顺时针转动30度变为第二相位，阀门开启点。塞体再顺时针转动60度变为第三相位，阀门全开启。塞体再顺时针转动60度变为第四相位，阀门关闭点。塞体再顺时针转动30度变为第五相位，与第一相位同相，阀门全关闭。阀门开程相位总共120度。
图5B-B剖面的塞体相位连续变化图中示意了连续变化的五种塞体相位，图中自左向右依次为第一相位1，第二相位2，第三相位3，第四相位4和第五相位5。当塞体匀速转动时，拨叉左移。从第一相位阀门全关闭状态开始，塞体顺时针转动25度变为第二相位，阀门开启点。塞体再顺时针转动65度变为第三相位，阀门全开启。塞体再顺时针转动65度变为第四相位，阀门关闭点。塞体再顺时针转动25度变为第五相位，与第一相位同相，阀门全关闭。阀门开程相位总共130度。与拨叉右移时的A-A剖面的塞体相位连续变化图相比，在本图拨叉左移时的B-B剖面的塞体相位连续变化图中，开启点相位提前了5度，关闭点相位滞后了5度，开程相位总共延长了10度。这就是第一副开闭件的两种相位调节效果。
在拨叉轴向右移或左移时，其他五个塞体异形通孔与五组阀体通孔形成的另外五副开闭件，其开启点、关闭点、开程的相位的两种相位调节效果与第一副开闭件的两种相位调节效果是同样的。
本发明结构形式二。阀体左侧设置三组六个阀体通孔，三组六个阀体通孔在同一轴向位置沿圆周方向均布设置。阀体右侧设置内侧为360度内空环状凹槽状的供流腔，并设置常开的流体入口使流体随时足量流入供流腔。塞体为带中心空心管的圆柱体，塞体左侧设置一组两个径向相对的塞体异形通孔，可以与阀体通孔配合形成一副多孔开闭件。塞体右侧设置一组两个径向相对的塞体方形通孔，可以与供流腔形成常通的流道使流体随时足量流入塞体中心空心管。参见图4。
本发明结构形式二的动力盘在轴承支撑下受动力源带动转动，通过内花键带动外花键转动，因此塞体、阀杆、拨环与动力盘同相位转动。转动中，塞体异形通孔与各阀体通孔配合形成的开闭件在每一个阀体通孔的开闭动作具有不同的开启点、关闭点、开程的相位。
与结构形式一同理，当本发明结构形式二的塞体转动时，控制拨叉沿轴向右移或左移，带动转动中的拨环、阀杆、塞体右移或左移。与六个阀体通孔配合形成开闭件的两个塞体异形通孔的轴向位置段与圆周向尺寸发生改变，六个阀体通孔的开启点、关闭点、开程的相位发生改变，由此调节相位，由此调节流体流量。结构形式二用于从一个主干流道向六个支路流道分时输送流体且需要调节开闭动作相位的开关控制。主干流道就是流体入口、供流腔、塞体方形通孔、塞体中心空心管，六个支路流道就是六个阀体通孔。塞体转动一周，六个阀体通孔各开闭两次。
本发明塞体采用异形通孔，通过控制拨叉轴向右移或左移，带动塞体异形通孔轴向右移或左移，在塞体匀速转动时可以调节开闭动作相位，在流体不变条件下可以调节流体流量。

具体实施方式
以下结合附图和具体实施例，对本发明做进一步说明。
实施例1：本发明塞体轴向移动调节开闭动作相位调节流量的旋塞阀的结构形式一作为直列三缸活塞式发动机的进气门、排气门。
塞体轴向移动调节开闭动作相位调节流量的旋塞阀结构形式一，包括：动力盘1、轴承2、内花键3、外花键4、阀杆5、拨环6、拨叉7、塞体8、阀体10。
动力盘1为圆盘，左侧为圆柱体，支撑在轴承2上，并连接内花键3。动力盘1在轴承2支撑下转动，不轴向移动。塞体8为圆柱体，塞体8上沿轴向设置六个塞体异形通孔9，塞体异形通孔指该通孔在不同轴向位置段的圆周向尺寸不同，就是通孔尺寸沿轴向变化大小。塞体8通过阀杆5与外花键4连接，阀杆5上设有拨环6，拨环6位于拨叉7的卡槽中，拨环6与拨叉7采用相对低阻力设置，拨环6在拨叉7卡槽中转动。当拨叉7沿轴向右移或左移时，带动拨环6、阀杆5、塞体8和外花键4沿轴向右移或左移。(常有人采用拨杆与拨槽的组合代替拨叉与拨环的组合，作用是一样的。)内花键3与外花键4相对轴向移动滑动，两者转速相同。阀杆5为圆柱体，拨环6为圆环体，与阀杆5共轴连体。拨叉7为U形卡槽，左右移动不转动。阀体10为圆管状体，阀体10内壁与塞体8外壁密切接触。阀 体10设置六组十二个径向通孔11，每组阀体通孔11都对应相同轴向位置段的塞体异形通孔9，形成控制流道开闭动作的开闭件。
阀体10沿轴向依次设置六组十二个阀体通孔11，每组有一上一下、径向相对的两个阀体通孔。塞体8从左到右设置六个塞体异形通孔9，六个塞体异形通孔9的轴向位置分别对应六组阀体通孔11的轴向位置，与阀体通孔11配合形成六副开闭件，六个塞体异形通孔9在阀门全开启时的塞体相位根据实际需要相互错开圆周方向相位设置。在本实施例就是按三缸发动机的各缸进气门排气门开闭动作的需要相互错开圆周方向相位设置。
把本实施例1旋塞阀设置于直列三缸发动机缸盖之中，使塞体8的转动轴线与发动机的直列三缸排列线平行，使阀体10和轴承2与发动机缸盖固定连接。六组阀体通孔11中，左起第一、第三、第五组通孔各置于三缸的进气管道中作为一缸、二缸、三缸的进气门，左起第二、第四、第六组通孔置于三缸的排气管道中作为一缸、二缸、三缸的排气门。按发动机工作时各缸的工作顺序、按各缸进气门排气门所需全开启相位设置各塞体异形通孔9全开启时的圆周方向相位，使各缸需要开启进气门排气门时对应的塞体异形通孔9处于与阀体通孔11配合开启的相位，使各缸需要关闭进气门排气门时对应的塞体异形通孔9处于与阀体通孔11配合关闭的相位。按发动机工作时调节进气门、排气门的开启点、关闭点、开程相位所需设置塞体异形通孔9在各轴向位置段的圆周向尺寸，就是按进气门排气门调节的需要设置异形通孔的一头大一头小的形状，使异形通孔具有进气门排气门所需相位调节变化所对应的形状。设置拨叉7受控制系统控制沿轴向右移或左移。动力盘1通过正时皮带与曲轴正时轮连接，使曲轴每转动四周，动力盘1转动一周，塞体8同相位转动一周，各进气门排气门各开闭两次。
本实施例1的发动机工作时，动力盘1在轴承2支撑下通过带传动受曲轴带动转动。塞体8、阀杆5、拨环6与动力盘1同相位转动。当塞体8转动时，控制拨叉7轴向右移或左移，带动转动中的拨环6、阀杆5、塞体8右移或左移。与阀体通孔11配合形成开闭件的六个塞体异形通孔9的轴向位置段与圆周向尺寸发生改变，六副开闭件的开启点、关闭点、开程的相位发生改变，由此调节相位，由此调节流体流量。在本实施例1中就是调节各缸进气门排气门的开闭动作相位和进气排气流量。
通过右移拨叉7带动塞体8右移，各塞体异形通孔9中左侧较小的圆周向尺寸通孔与相应的阀体通孔11配合，可以形成第一、第三、第五进气门的开启点相位相对延后、关闭点相位相对提前、开程相位相对减短，第二、第四、第六开闭件排气门的开启点相位相对延后、关闭点相位相对提前、开程相位相对缩短。这种发动机进气排气相位的调节变化有利于发动机发挥低速大扭矩性能。参见图2。通过左移拨叉7带动塞体8左移，各塞体异形通孔9中右侧较大的圆周向尺寸通孔与相应的阀体通孔11配合，可以形成第一、第三、第五进气门的开启点相位相对提前、关闭点相位相对延后、开程相位相对加长，第二、第四、第六开闭件排气阀的开启点相位相对提前、关闭点相位相对延后、开程相位相对加长。这种发动机进气排气相位的调节变化有利于发动机发挥高速大功率性能。参见图4。
采用本发明塞体轴向移动调节开闭动作相位调节流量的旋塞阀的结构形式一作为发动机的进气门排气门，适用于不同缸数的发动机。比传统凸轮轴顶杆式的进气门排气门结构简单，自重减轻，节约能耗。在发动机运行时，本实施例1这样的进气门排气门非常容易通过控制拨叉轴向右移或左移来调节进气门排气门的开闭动作相位、调节进气排气流量，相当于现有的发动机的可变正时、可变开程气门系统。
实施例2：本发明塞体轴向移动调节开闭动作相位调节流量的旋塞阀的结构形式二作为从一个主干流道向六个支路流道分配流量的阀门。
塞体轴向移动调节开闭动作相位调节流量的旋塞阀的结构形式二包括：动力盘1、轴承2、内花键3、外花键4、阀杆5、拨环6、拨叉7、塞体8、阀体10。
动力盘1为圆盘，左侧为圆柱体，支撑在轴承2上，并连接内花键3。动力盘1在轴承2支撑下转动，不轴向移动。塞体8为圆柱体，塞体上沿轴向设置一组两个异形通孔9，异形通孔指该通孔在不同轴向位置段的圆周向尺寸不同，就是通孔尺寸沿轴向变化大小。塞体8通过阀杆5与外花键4连接，阀杆4上设有拨环6，拨环6位于拨叉7的卡槽中，拨环6与拨叉7采用相对低阻力设置，拨环6在拨叉7卡槽中转动。当拨叉7沿轴向右移或左移时，带动拨环6、阀杆5、塞体8和外花键4沿轴向右移或左移。(常有人采用拨杆与拨槽的组合代替拨叉与拨环的组合，作用是一样的。)内花键3与外花键4相对轴向移动滑动，两者转速相同。阀杆5为圆柱体，拨 环6为圆环体，与阀杆5共轴连体。拨叉7为U形卡槽，左右移动不转动。阀体10为圆管状体，阀体10内壁与塞体8外壁密切接触。阀体10左侧设置三组六个阀体通孔11，三组六个阀体通孔11在阀体10的同一轴向位置沿圆周方向均布设置。阀体10右侧设置内侧为360度内空环环凹槽状的供流腔14，并设置常开的流体入口13使流体随时足量流入供流腔14。塞体8为中心空心管的圆柱体，塞体8左侧设置一组两个径向相对的塞体异形通孔9，与阀体通孔11配合形成一副多孔开闭件。塞体8右侧设置一组两个径向相对的方形通孔15，与供流腔14形成常通的流道使流体随时足量流入塞体中心空心管12。
本发明结构形式二的动力盘1在轴承2支撑下受动力源带动转动，通过内花键3带动外花键4转动，因此塞体8、阀杆5、拨环6与动力盘1同相位转动。转动中，两个塞体异形通孔9与各阀体通孔11配合形成的开闭件在每一个阀体通孔11的开闭动作具有不同的开启点、关闭点、开程的相位。
当塞体8转动时，控制拨叉7沿轴向右移或左移，带动转动中的拨环6、阀杆5、塞体8右移或左移。与六个阀体通孔11配合形成多孔开闭件的两个塞体异形通孔9的轴向位置段与圆周向尺寸发生改变，六个阀体通孔11的开启点、关闭点、开程的相位发生改变，由此调节相位，由此调节流体流量。本实施例2用于从一个主干流道向六个支路流道分配流量且需要调节开闭动作相位调节流量的阀门。当设置阀体通孔11为其他数量时，就是向其他数量的支路流道分配流量。根据需要，塞体异形通孔9也采用其他数量等设置方式。
本实施例2塞体8采用塞体异形通孔9，通过控制拨叉7轴向右移或左移，带动塞体异形通孔9轴向右移或左移，在塞体8匀速转动时各开闭件开闭动作相位可以调节，在流体压差不变条件下各支路流道的流体流量可以调节。
