实施例一
图 1为本发明实施例一提供的逆水阀的剖面图， 图 2为本发明实施例一 提供的逆水阀座的主视图一， 图 3为本发明实施例一提供的逆水阀座的俯视 图， 图 4为本发明实施例一提供的逆水阀座的主视图二， 图 5为本发明实施 例一提供的逆水阀座的主视图三， 图 6为本发明实施例一提供的逆水阀座的 立体图一， 图 7为本发明实施例一提供的逆水阀座的立体视图二， 图 8为本 发明实施例一提供的逆水阀座的立体图三。 如图 1至图 8所示， 逆水阀可以 包括逆水阀盖 11、 逆水阀杆 12、 密封圈 13、 逆水阀座 14和逆水弹簧 15。
其中， 逆水阀座 14中开设有贯通的过水孔 141和中心孔 142， 逆水阀 座 14的中心孔 142为圆柱形； 逆水阀盖 11遮盖在逆水阀座 14的过水孔 141处， 逆水阀盖与逆水阀座之间设有密封圈 13， 且逆水阀盖 11 的下表 面与密封圈 13的上表面形状匹配设置，密封圈 13的下表面与逆水阀座 14 的上表面形状匹配， 以使逆水阀盖与逆水阀座能够保持贴紧状态。 逆水阀 盖 11中也开设有贯通的中心孔， 该中心孔也为圆柱形； 逆水阀杆 12的一 端穿过逆水阀盖 11 的中心孔， 并与逆水阀盖 11 固定连接， 逆水阀杆 12 的另一端依次穿过密封圈 13和逆水阀座 14 的中心孔 142。 逆水阀盖 11 的中心孔的直径小于逆水阀座 14的中心孔 142， 相应的， 逆水阀杆 12的 直径与上述各中心孔的直径匹配设置， gP : 逆水阀杆 12位于逆水阀盖 11 中的直径小于位于逆水阀座 14中的部分。 逆水阀杆 12伸出逆水阀盖 11 的一端设置有螺紋， 并通过螺母和垫片配合将逆水阀杆 12与逆水阀盖 11 固定连接。 逆水弹簧 15固定在逆水阀座 14和逆水阀杆 12之间， 用于在 逆水阀盖 11受压离开过水孔时通过逆水阀杆 12带动逆水阀盖 11复位至 遮盖过水孔的位置。逆水阀杆 12伸出逆水阀座 14的一端固定连接一螺母，
该螺母与逆水弹簧 15之间留有一段距离， 使得逆水阀杆 12能够在逆水阀 座 14的中心孔 142中沿中心孔 142的轴线方向移动。逆水阀盖 1 1和逆水 阀座 14之间设置的密封圈 13可以为橡胶密封圈， 用于在逆水阀盖 1 1和 逆水阀座 14贴紧时起到密封的作用。
逆水阀座 14中设置有至少两个过水孔 141，且每个过水孔 141的轴线 与逆水阀座 14的中心孔 142的轴线为异面设置的直线， 或过水孔 141的 轴线为绕逆水阀座 14的中心孔 142 的轴线的螺旋线， 以使水流呈螺旋状 射出逆水阀。 各螺旋线的方向一致， 可以为顺时针， 也可以为逆时针。 对 上述过水孔 141的轴线可以作如下定义：在轴线上任意一点（假设为 0点） 有唯一的切线和唯一的切平面， 则在该切平面上， 经过 0点并与该切线垂 直的直线与过水孔 141的内壁有两个交点， 均与 0点的距离相等， 具有上 述特征的线条定义为过水孔 141的轴线。 则对于轴线为直线的过水孔 141 为直孔， 对于轴线为螺旋线的过水孔 141为螺旋状的弯曲形孔。 将逆水阀 座 14远离密封圈 13的表面称为入水表面， 靠近密封圈 13的表面称为出 水表面。 将过水孔 141 中远离密封圈 13的一端为逆水入口， 靠近密封圈 13的一端为逆水出口。 上述逆水阀座 14中过水孔 141 的数量优选设置为 四个， 其孔径的尺寸可根据逆水阀座 14的尺寸设定， 各过水孔 141可以以 逆水阀座 14中心孔 142的轴线呈中心对称排布。
对于上述直孔形的过水孔 141， 其轴线为直线， 且与逆水阀座 14中心孔 142的轴线为异面设置， 各过水孔 141沿逆水阀座 14中心孔 142的轴线呈中 心对称， 可参照图 1和图 2中所示的过水孔 141。 对于上述螺旋状的弯曲形 的过水孔 141， 其轴线绕逆水阀座 14中心孔 142呈螺旋线， 其螺旋半径可以 相等， 各过水孔 141沿逆水阀座 14中心孔 142的轴线呈中心对称， 可参照图 4至图 7中所示的过水孔 141。
以过水孔 141为顺时针方向排布为例， 上述逆水阀的工作过程为： 在 逆水阀关闭状态时， 逆水阀盖 1 1 向下贴紧密封圈 13， 进而贴紧逆水阀座 14 , 将逆水阀座 14的过水孔遮盖， 且逆水弹簧 15处于松弛状态。 当一定 压力的水流从逆水阀的逆水入口进入过水孔 141， 从逆水出口流出， 水流 的冲击力将逆水阀盖 1 1 顶开， 即逆水阀处于打开状态， 且水流沿顺时针 方向从各过水孔 141射出逆水阀座 14， 此时逆水弹簧 15处于压缩状态。
当从逆水阀座 14射出的水流压力降低至小于逆水弹簧 15的张力时， 或者 当逆水阀盖 11受到来自于水流方向相反的外部压力且与逆水弹簧 15的张 力之和大于水流压力时， 逆水弹簧 15张开， 并带动逆水阀盖 11朝向逆水 阀座 14移动， 贴紧逆水阀座 14， 以遮盖逆水阀座 14的过水孔 141。 若将 逆水阀与一空气罐密闭连接， 空气罐设置在逆水阀的上方， 当逆水阀打开 时， 水流从逆水阀的下方进入逆水阀座 14， 并朝向密闭的空气罐中喷射水 流， 则水流从各过水孔 141沿顺时针方向呈螺旋状射入空气罐中， 受到空 气罐内壁的阻挡形成涡流， 也带动空气罐中的气体旋转， 形成气旋。 水流 不断增多， 对空气的压缩力也逐渐加大， 使得空气罐内的压力增大。
本实施例采用的技术方案中逆水阀的过水孔至少两个， 且每个过水孔的 轴线与逆水阀座中心孔 142的轴线为异面设置的直线或过水孔轴线为绕中心 孔 142轴线的螺旋线， 以使水流呈螺旋状射出逆水阀， 改变了现有过水孔垂 直设置或过水孔整体倾斜设置的现状，使喷射出的水流减小逆水阀盖的阻挡， 进而能够解决现有的水泵中对空气罐中的气体压缩力度较小的问题， 实现 提高逆水阀的出水速度和出水量。
在上述技术方案的基础上， 过水孔 141的孔径优选为均匀分布。 对于 轴线为螺旋线的过水孔 141， 其形状还可以设置为： 过水孔 141的螺旋线轴 线在该螺旋线轴线与逆水阀座 14出水表面相交点处的切线与逆水阀座 14出 水表面呈设定角度， 可参照图 5所示的过水孔 141。 对于过水孔 141的轴线 为直线而言， 可以理解为经过过水孔 141 的直线形轴线的中点， 且与该中点 与逆水阀座 14的中心孔 142的轴线所在平面垂直的平面与过水孔 141的直线 形轴线呈设定角度。 该设定角度可以为 30-60度之间的任意角度， 优选为 45度， 能够进一步扩大水流出射的角度， 提高旋流的旋转速度。
各过水孔 141的轴线绕逆水阀座 14中心孔 142的轴线为中心对称， 对于过水孔 141轴线为螺旋线的逆水阀座 14，其螺旋半径可以相等，因此， 可作出多个角度的剖视图， 如图 4和图 5为两个角度得到的剖视图。 当过 水孔 141 的孔径较大时， 在逆水阀座 14的俯视图中可以看到过水孔 141 贯通于逆水阀座 14， 例如图 3 中的 A区域即为从俯视的角度看逆水阀座 14 , 能看到过水孔贯通的区域。
另外， 过水孔与逆水阀座 14的入水表面和出水表面相交得到的形状，
也就是逆水入口和逆水出口的形状可以为如图 6所示的椭圆形或如图 3、 图 7以及图 8所示的形状， 当然也可以由技术人员设定为其它形状。 实施例二

空气罐 3包括罐体 31、 出水管 32和扬水管， 其中， 罐体 31的下端通 过法兰与泵体 2固定连接， 出水管 32可设置于罐体 31上， 现有技术中的 出水管 32与罐体 31顶端的距离为罐体 31高度的三分之二， 而本实施例 提供的出水管 32设置在与罐体 31顶端的距离为罐体 31高度的二分之一 处， 或位于二分之一略向下处， 具体可根据空气罐 31 的直径、 高度、 以 及从逆水阀出射的水流速度和角度经过多次试验和测试来设定， 以使出水 管 32位于水压最大处。 出水管 32的一端可焊接在罐体 31的表面， 另一 端接扬水管， 扬水管作为节能水泵的出水口向上延伸至设定高度， 扬水管 的长度可根据需要设定。 出水管 32也可以与空气罐的罐体 31设置为一体 成型， 以避免出现漏水的现象。
冲击阀 4包括冲击头 41、 冲击套管 42、 冲击盘 43、 冲击弹簧 44、 冲 击导管 45以及冲击支架 46。其中，冲击支架 46固定设置在泵体 2的内部， 具体通过泵体后盖 21固定在泵体后盖 21与泵体 2的连接处， 该冲击支架 46为圆锥形三角支架， 开设有中心孔。 冲击套管 42的一端依次穿过冲击
支架 46的中心孔和冲击盘 43的中心孔， 并与冲击盘 43固定连接。 该冲 击盘 43通过螺母与冲击套管 42固定连接， 且可沿冲击盘 43的中心孔轴 线方向滑移。 冲击套管 42露出于冲击支架 46的另一端设置有冲击头 41， 该冲击头 41的前端为圆锥体， 后端为圆柱体， 冲击头 41的后端插入冲击 套管 42并与其固定连接。 冲击弹簧 44设置在冲击套管 42的内部， 并与 冲击头 41的后端连接，在冲击阀 4打开状态下，冲击弹簧 44为松弛状态， 在冲击阀 4关闭状态下， 冲击弹簧 44为压缩状态， 冲击弹簧 44用于当水 流压力降低时， 由自身的扩张力推动冲击套管 42带动冲击盘 43复位至冲 击阀 4打开状态。冲击套管 42可在冲击支架 46的中心孔中沿冲击支架 46 的轴线方向滑移， 且带动冲击盘 43同步滑移。 冲击导管 45从泵体 2的外 部穿入泵体 2， 穿设在冲击套管 42中， 且与冲击弹簧 44之间留有一定的 距离。 冲击导管 45与泵体 2固定连接， 具体可与泵体后盖 21固定连接。 冲击导管 45通过调节螺母 48固定在泵体后盖 21上， 当调节螺母 48旋松 时， 冲击导管 45可在冲击套管 42中移动， 以调节冲击头 41与泵体 2进 水口的距离， 进而改变水流撞击冲击头 41 后压力的增量。 调节方法为： 首先将调节螺母 48旋松， 然后调节冲击导管 45伸入泵体 2的长度， 调节 好后再拧紧调节螺母 48将冲击导管 45与泵体后盖 21固定。
该流体动力节能水泵的工作过程为： 当进水闸阀打开时， 水流经过进 水管道的不断加速， 以高于水源压力数十倍的压力进入泵体 2， 撞击在冲 击阀 4中的冲击头 41上， 此过程可以称为为第一加力段。 由于冲击头 41 的前端为圆锥形， 水流被冲击头 41 分散成多股水流， 水流得到增压并扩 散流向冲击阀 4的后方， 同时， 冲击套管 42在水流压力的作用下带动冲 击盘 43 向冲击阀 4的后方滑移， 直至到达极限位置， 封闭排水口， 以使 冲击阀 4处于关闭状态， 此时冲击弹簧 44处于压缩状态。 水流不断涌入 泵体 2， 使得泵体 2内的水压逐渐增大， 当大于逆水阀 1的压力极限时， 逆水阀盖 1 1 自动打开， 水流从逆水口进入逆水阀 1， 经过逆水阀 1中的过 水孔 141， 形成设定角度的螺旋状射流射出逆水阀 1， 进入空气罐 3。 射出 的水流受到空气罐 3内壁的阻挡而转变射流方向， 形成涡流， 并带动空气 罐 3中的气体旋转， 形成气旋。 进入空气罐 3的水流不断增多， 将气体压 缩到空气罐 3的顶部， 该过程可称为第二加力段。 当水流从泵体 2进入空
气罐 3后， 泵体 2 内的压力急速下降， 受压后移的冲击盘 43和冲击套管 42在冲击弹簧 44的作用下快速复位。 在复位过程中， 还会有部分水通过 冲击盘 43和泵体后盖 21的间隙从排水口流出， 减小了泵体 2内的压力。 但泵体 2内的压力下降至逆水阀 1关闭的极限压力时， 逆水阀盖 1 1 自动 下落关闭。 之后， 空气罐 3中的涡流急速扩散， 产生反向压力， 该过程可 以称为第三加力段， 水流进入扬水管 32， 排出空气罐 3外， 实现一次扬水 过程。 当逆水阀 1关闭后， 水流继续涌入泵体 2增压， 当泵体 2中的压力 到达逆水阀 1的压力极限时， 逆水阀 1再次打开， 以使水流射入空气罐 3。 水流源源不断流入泵体 2， 冲击阀 4和逆水阀 1反复重复上述动作， 实现 连续扬水。
上述实施例提供的流体动力节能水泵通过采用泵体、 空气罐、 逆水阀 和冲击阀形成三个水流加力段， 并采用上述实施例所提供的逆水阀， 使得 从逆水阀喷射出的水流不受逆水阀盖的阻挡， 直接射出逆水阀， 提高水流出 射速度和出水量， 能够解决现有的水泵中对空气罐中的气体压缩力度较小 的问题， 实现提高水泵扬程高度， 增大水流量。
在上述技术方案的基础上， 冲击阀 4还可以包括冲击后座 47， ， 该冲 击后座 47可以与泵体 2可拆卸地连接。 具体的， 冲击后座 47通过螺栓与 泵体 2连接， 具体可以与泵体后盖 21连接， 当需要对泵体内部的器件进 行维修时， 只打开冲击后座 47即可， 而不需要将泵体后盖 21拆下， 能够 简化维修操作， 提高工作效率。
另外， 泵体 2上还可以设置有操作杆， 操作杆的一端穿设在冲击套管 42中， 与冲击头 41连接， 另一端露出于泵体 2外， 用于手动操作该节能 水泵工作。具体的， 操作杆包括第一连杆 51、第二连杆 52和第三连杆 53， 其中， 第一连杆 51的一端连接至冲击后座 47， 另一端与第二连杆 52的其 中一端连接， 第三连杆 53的一端连接至第二连杆 52的中部， 第三连杆 53 的另一端从冲击导管 45中穿过， 再穿入冲击套管 42中， 与冲击头 41连 接。 操作人员可以通过拉动第二连杆 52带动第三连杆 53推动冲击头 41 移动，进而实现冲击阀 4的打开与关闭，其工作原理与自动运行过程一致。 当冲击套管 42后移压缩冲击弹簧 44使得冲击阀 4关闭， 会出现冲击弹簧 44受压较大， 出现过度压缩， 而不能自动复位的情况， 则需要外力通过拉
动第二连杆 52， 推动冲击盘 43和冲击套管 42移动， 以使冲击弹簧 44松 弛， 冲击阀 4复位至打开状态。
本领域技术人员可根据水源的水位差、进水管道的倾斜角度调节冲击 导管 45的位置， 以使得该节能水泵的扬程达到 10-35米， 出水量为 4-45 吨。
上述节能水泵可采用铸铁、 铸钢、 铝合金或塑钢等多种材料制成， 可 制成多种型号， 可根据水源差和进水管道的倾斜角度来设计不同尺寸的节 能水泵， 例如扬水管的出水口为 1. 5吋、 3吋、 6吋以及其它尺寸的节能 水泵。 单个节能水泵可独立工作， 也可以将多个节能水泵组合工作， 例如 多个节能水泵中扬水管的出水口均与一个管径较粗的出水管路连接， 以使 多个节能水泵流出的水汇入出水管路， 可以在各节能水泵中扬水管的出水 口处设置速度传感器或流量传感器， 用于检测出口水流的速度或流量。 各 传感器连接至控制显示设备， 将检测到的数据传送给控制显示设备， 用于 监测各节能水泵的工作状态。还可以将节能水泵与蓄水池或蓄水塔等设备 配合使用， 更能够拓宽该节能水泵的应用范围。
上述节能水泵不消耗任何资源， 也不会排放任何污染， 仅以水位差作 为动力实现扬水， 可应用在农林业中， 用于浇灌、 喷洒、 滴灌等多种形式； 也可应用在生活中，用于塔供自来水；也可在旅游景点中设计为人造瀑布、 喷泉以及流溪等景观。 多泵组合可向用水量较大的厂矿供水， 以节省电力 资源、 燃料， 进而节约成本。
以燃烧柴油作为驱动力的机械水泵和以电力作为能源的电力水泵为 例， 与上述实施例所提供的节能水泵相比较， 其节能效果可参见表一： 表一 节能水泵与柴油机水泵和电力水泵的节能效果对照表
另外， 从排污量的角度考察节能水泵的优势， 如表二， 在实验过程， 操作人员身穿白色工作服：
再者， 从使用安全性的角度出发， 在柴油机水泵启动时， 需要操作人 员手摇柴油机水泵外壳上设置的飞轮， 飞轮持续转动才能保证柴油机水泵 连续工作。 在启动点火时， 飞轮容易倒转会出现打伤操作人员的手臂的危 险发生， 飞轮高速转动时也很难实现立即停止， 且柴油机水泵经过长时间 工作后， 其排气筒的温度高达 150 ° ， 容易出现烫伤事故， 使用过程较危 险。 对于电力水泵， 其输入电源通常为 220V或 380V , 且电力水泵的运行
过程时刻与水接触， 容易发生漏电进而导致人体触电现象发生， 因此电力 水泵也存在着安全隐患。 而节能水泵的机械结构是封闭在泵体内部， 不会 对操作人员身体造成伤害， 且节能水泵在运行过程中不需要操作人员长期 看守， 具有较高的安全性。
综上所述，上述实施例所提供的流体动力节能水泵能够达到较高的扬 程和出水量， 且不消耗任何燃料， 实现零排放零污染， 有较高的安全性， 其制造成本及维护成本较低。
另外， 专利 ZL 200820135524. 1提出的水泵中逆水阀的过水孔为垂直 设置或过水孔整体倾斜设置， 所喷射的水流冲顶开逆水阀盖的同时也使部 分水流受逆水阀盖阻挡回落直接影响逆水阀的喷射效果， 降低了对空气罐 中的气体压缩力度， 使得水泵的扬程高度在 2米左右， 出水量在 0. 5吨左 右。 与之相比， 上述实施例提供的节能水泵的扬程高度和每小时出水量均 有明显提高， 以 3 吋泵为例， 其扬程能达到 （10-20 ) 米， 出水量能达到 ( 20-30 ) 吨 /小时， 当水源落差大于 0. 8米， 或当进水管道增压较大时， 扬程甚至会达到 26米。 对于出水口大于 3吋的节能水泵， 其扬程能够实 现大于 35米， 出水量大于 45吨。
最后应说明的是： 以上各实施例仅用以说明本发明的技术方案， 而非对 其限制； 尽管参照前述各实施例对本发明进行了详细的说明， 本领域的普通 技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改， 或者对其中部分或者全部技术特征进行等同替换； 而这些修改或者替换， 并 不使相应技术方案的本质脱离本发明各实施例技术方案的范围。
