实施该发明的最佳实施例
本发明的最佳实施方式
根据附图对本发明提供的优选实施方式做具体说明。
图3，为本发明提供的压差动力结构的第一种优选实施方式。如图3所示，该压差动力结构包括用于供流体流动的流体管道10以及压差管，压差管包括设于流体管道内一端开口方向与流体流向相对的第一主管20以及设于流体管道内一端开口方向与流体流向相同的第二主管30，第一主管20和第二主管30的轴线与流体管道10的轴线处于同一直线上，第一主管20的另一端开口连通有伸出流体管道外用于与外部管道连接的第一支管40，第二主管的另一端开口连通有伸出流体管道外用于与外部管道连接的第二支管50，第一支管40与第二支管50之间采用管道连通，第一支管40与第二支管50的中心轴线之间的间距为L，0≤L≤200cm，第一主管20中与流体流向相对的开口记为逆流开口端21，第二主管中与流体流向相同的开口记为顺流开口端31，流体管道10内的一部分流体进入第一主管20的逆流开口端21，再从第一支管40流出；而从第二支管50进入的流体再从第二主管30的顺流开口端31流出，将第一主管10的逆流开口端11的端面中心上的压力记为PA，将第二主管20的顺流开口端21的端面中心上的压力记为PB，经过测 量会发现PA明显大于PB。
第一支管40与第一主管20可设置为垂直状态或非垂直状态，同样地，第二支管50与第二主管30也可设置为垂直状态或非垂直状态。作为一种优选实施方式，第一支管40垂直于第一主管20，第二支管50垂直于第二主管30，这样保证流体流通的顺畅性以及加工制造的方便。
第一支管40和第二支管50的中心轴线可以保持平行或交叉，特别是在第一支管40与第二支管50中心轴线的间距为0时，二者的中心轴线处于同一平面上，可以分为平行状态或交叉状态，平行状态中较为特殊的状态为重合状态。图3所示，即为所述第一支管40以及第二支管50的中心轴线处于同一平面上且保持平行；图5和图6所示，即为所述第一支管40以及第二支管50的中心轴线处于同一平面上且保持重合；图7所示，即为所述第一支管40与第二支管50的中心轴线处于同一平面上且相互垂直。
作为一种优选实施方式，如图3所示，两个支管之间采用管道连接为一体，从第一主管20进入流体，再进入第一支管40，第一支管40内的流体直接流入第二支管50，最后从第二主管30中流出。
作为一种优选实施方式，如图4所示，所述第一主管20与第一支管40的连接端采用倾斜隔板60密封，第二主管30与第二支管50的连接端采用倾斜隔板60密封，这样在流体冲击到倾斜隔板60时，可产生冲击力，使得流体更易发生转向。倾斜隔板60与水平面的夹角范围为β，0＜β≤90°，优选β为45°。在在第一支管40与第二支管50中心轴线的间距为0，两个倾斜隔板60重合为一体，这样将第一主管20、第二主管30、第一支管40以及第二支管50连接为一个整体。
第一主管20、第二主管30、第一支管40以及第二支管50四者的直径可相同，也可各不相同。所流体管道10的直径与所述第一主管20的直径比≥2.5；所述流体管道10的直径与所述第二主管30的直径比范围为≥2.5。作为一种较佳的优选实施方式，该第一主管20、第二主管30、第一支管40以及第二支管50的直径保持相同。
如图8至图12，为将本发明提供的第三种优选实施方式应用到胶球清洗装置中。所述端盖式胶球清洗装置包括封头管箱1、进水管2和出水管3，还包括收球滤 网、球水分离器、控制器、阀门和管路等；封头管箱1内设有上管箱101和下管箱102，上管箱101的前端连通出水管2的入口，出水管3内设有收球滤网301，出水管3内还设有压差管甲4，压差管甲4有甲出水口401、甲出球口402、甲入球口403、甲入水口404，中间设有隔板405使得甲出水口仅与甲入水口连通，甲出球口仅与甲入球口连通，甲出水口与出水管的出口在同侧，甲入球口403与收球滤网301连通，甲出球口402和甲入水口404分别于与连通球水分离器6的管路相连；下管箱102的前端连通进水管2的出口，进水管2内设有压差管乙5，压差管乙5有乙入水口501、乙入球口502、乙出球口503、乙出水口504，中间设有隔板505使得乙入水口仅与乙出水口连通，乙入球口仅与乙出球口连通，乙入水口与进水管的入口在同侧，乙出球口与进水管的出口在同侧，乙入球口和乙出水口分别于与连通球水分离器6的管路相连，该球水分离器6连通有控制阀7，球水分离器6上设有发球口602、收球口601和滤网603，发球口602与乙入球口502连通，收球口601与甲出球口402连通；控制阀7上具有进水口701、出水口702，进水口701与乙出水口，504连通用于供高压水流入，出水口702与甲入水口404连通用于供低压水流出。
如图9所示，在进行收球时，球水分离器6中出球口602关闭，控制阀7的进水口701关闭，P1大于P2，在出水管3中，压差ΔP推动水流带着胶球进入甲入球口403，再从甲出球口402进入球水分离器6的收球口601，一部分水流从控制阀7的出水口702进入甲的入水口404内，最后从甲出水口401流入出水管3内；在进行发球时，球水分离器6中入球口601关闭，控制阀7的出水口702关闭，P3大于P4，压差ΔP推动水流从乙入水口501进入，途径乙出水口504，控制阀7的进水口701进入球水分离器6中，带动球水分离器6中的胶球经过发球口602发球，进入乙入球口502，乙出球口503后进入封头管箱内，完成对冷凝器清洗后回到收球管内的收球滤网301中。
值得注意的是，进水管以及出水管即为流体管道，压差管处于该流体管道内，这样利用进水的压差来实现发球和出水的压差来实现收球，这两个压差是利用流体力学原理，在管中心位置流速最高，逆流端口设置收球口，顺流端口设置在收球口的背后顺流方向，两个端口之间的压差ΔP足够大利于收球和发球，该 压差成为收发球的动力。
压差模拟实验对照
在计算机软件Solidworks中进行模拟仿真实验：使用三维几何建模软件Solidwor ks分别进行通管、弯管和压差管的实体建模，并导入Flow Simulation分析模块完成压差仿真分析计算。如图13、图14和图15所示，将通管、弯管及压差管都置于流体管道中，且各管的进水端和出水端都处于流体管道的中心轴线上，压差管中第一支管40与第二支管50通过管道连通；流体管道的管径为D，D＝309mm，压差管、通管以及弯管内各管的直径都为d，d＝70mm，通管、弯管及压差管进水端中心点记为A点，A点的压力为P A，通管、弯管及压差管出水端中心点记为B点，B点的压力为P B，压差管、通管以及弯管中每个管道A点与B点的水平距离为300mm，通管、弯管及压差管上A点与B点的压力差ΔP，Δp＝P A-P B，模拟压差结果如图16和图17所示。
经上述实验可知：在同一水流速度下，压差管两端的压差要明显大于通管两端、弯管两端的压差；而在水流速度逐渐增大的情形下，压差管两端的压差的差值增幅要明显大于通管两端、弯管两端的压差的差值增幅。
综上所述，本发明的技术方案可以充分有效的实现上述发明目的，且本发明的结构及功能原理都已经在实施例中得到充分的验证，能达到预期的功效及目的，在不背离本发明的原理和实质的前提下，可以对发明的实施例做出多种变更或修改。因此，本发明包括一切在专利申请范围中所提到范围内的所有替换内容，任何在本发明申请专利范围内所作的等效变化，皆属本案申请的专利范围之内。
