Description

一种可供软水设备吸盐口使用的双向流量计 技术领域
本发明涉及软水处理设备，尤其是一种可供软水设备吸盐口使用的双向流量计。
背景技术
软水处理设备的基本原理是通过树脂和水发生化学反应，置换水中的钙镁离子，起到对水软化的作用。树脂是可以循环利用的，当树脂失效后，可以利用盐水与树脂发生化学反应，让树脂重新具备软水功能。这种利用盐水来使树脂重新具备软水的功能称之为再生。
控制阀将树脂再生一般分为以下几个步骤：反洗，吸盐，正洗和注水。反洗的作用是将树脂由下而上进行反冲，将树脂冲散，为下一步吸盐做准备，让盐水与树脂能够更充分的接触。吸盐作用就是将盐水吸进树脂罐与树脂发生化学反应，让树脂重新具备软水功能。正洗和反洗相反，水流由上而下将树脂压紧，这样在软水过程中水流通过树脂速度会变慢，让树脂软化水的时间更加充分。注水指的是往盐箱里注水进行溶盐，为下次再生时吸盐做准备。每一次再生都需消耗一定量的盐。
软水处理设备一般都是通过控制阀同时控制多路水流，实现树脂再生操作。控制阀上设有多个管路接口，其中一个为吸盐口，在进行吸盐操作时，控制阀将盐箱内的盐液通过吸盐口吸入控制阀内管路，再通过控制阀与树脂罐子相连的管路接口注入树脂罐内，在进行注水时，控制阀内管路流通路径进行相应的切换，清水先通入控制阀内管，再通过控制阀吸盐口注入盐箱。
目前市面上的软水处理设备控制阀的吸盐口都没有配备流量计，主要有两个原因：1、吸盐口的水流速普遍比较小，很难满足流量计叶轮启动的条件；2、一般的叶轮轴为单点固定，受重力向下小角度倾斜，当水流经过，需要水流先将叶轮扶正托起才能开始旋转。
而为了计量注水量，如图1所示，一般是在控制阀的吸盐口加装橡胶垫，橡胶垫中心有一个开孔，可使水流从孔中间经过时保持一定的流速，当流速增加则橡胶垫发生变形，中间开孔变小，使水流变慢。再通过水流通过的时间来计算注水量。此计量方式为模糊计量，偏差较大。
综上所述，目前软水处理设备无法有效的对通过控制阀吸盐口的注水量和吸盐量进行准确计量。

如图4之6所示，所述流量计主体组件6包括流量计外壳6-1，流量计外壳6-1内 腔中部间隔设置两个流量计分流器6-4，流量计分流器6-4包括内圈和外圈，流量计分流器6-4外圈通过过盈配合的方式固定在流量计外壳6-1内腔壁上，流量计分流器6-4外圈与内圈之间通过若干筋条相连，在流量计分流器6-4内圈设有衬套6-6，在两个流量计分流器6-4之间设有叶轮6-7，叶轮6-7圆周上均布有若干叶片6-9，在两个相邻的叶片6-9之间设有磁钢6-8，叶轮6-7中心轴两端穿入衬套6-6内。
叶轮6-7中心轴由不锈钢制成，两端为圆度非常高的球面，叶轮6-7中心轴中间有凹槽，叶轮6-7为塑胶注塑成型件，当注塑成型时，叶轮6-7的内孔部分塑胶镶嵌到叶轮6-7中心轴凹槽内，可使叶轮6-7和和叶轮6-7中心轴之间固定，叶轮6-7不会轴向窜动。
优选的，所述叶轮6-7中心轴与衬套6-6间隙配合，叶轮6-7的中心轴可在衬套6-6内自由旋转，叶轮6-7中心轴两端球面嵌入刚玉6-5的弧形凹槽内，刚玉6-5通过过盈配合的方式固定在衬套6-6内壁。由于刚玉6-5具有硬度高、耐磨性能好的特点，可使叶轮6-7中心轴旋转的摩擦力非常小，可大大提高流量计主体组件6的使用寿命。
当水流通过流量计分流器6-4内圈与外圈之间的环形通道内时，可推动叶片6-9、叶轮6-7旋转，为了减小水流在流量计主体组件6内部的阻力，所述流量计分流器6-4内圈远离叶轮6-7的一侧具有弧形锥面6-12，这样，可使水流在弧形锥面6-12导向作用下分散成一个均匀的环状水流，然后流经叶片6-9，最大限度的减少流量计主体组件6内部水流动能损失。所以整个叶轮6-7体积可以做的非常小，不到现有叶轮的一半。
如图2和10所示，所述霍尔元件组件5包括磁感应探头5-1，磁感应探头5-1设置在流量计外壳6-1与叶轮6-7相对应的位置。
磁钢6-8有金属磁性件，可通过和磁感应探头5-1配合实现计数功能。磁钢6-8质量较大，一般的流量计体积较大，叶轮和轴心的距离也较大，为了保证能被霍尔元件5检测到，只能将磁钢尽量靠近叶轮边缘的位置。而此流量计的叶轮6-7体积较小，叶轮6-7和中心轴的距离也较小，保证了磁钢6-8在磁感应探头5-1的检测范围之内，这样启动叶轮6-7转动的启动力距会比较小，对水流流量要求较小。
如图2、7、8、9所示，所述水管3一端通过快速接头组件4与流量计外壳6-1内腔一端相连，水管3另一端与软水设备的盐箱相连；所述90°弯接头7一端通过快速接头组件4与流量计外壳6-1内腔另一端相连，90°弯接头7另一端与软水设备的控制阀吸盐口相连。
本实施例中，所述快速接头组件4包括快接外壳4-1、导套4-2，快接外壳4-1的尾端设有外螺纹接头4-5，外螺纹接头4-5与流量计外壳6-1内腔两端内螺口配合旋紧，导套4-2套入快接外壳4-1内腔前端，导套4-2外圈的卡耳4-6卡入外壳4-1内腔壁的 卡槽内，导套4-2内壁设有倒扣4-7。导套4-2、卡耳4-6、倒扣4-7为金属材质，三者可通过注塑一体成型金属注射一体成型。图7中示出了水管3与快速接头组件4的连接状态，将水管3端部插入导套4-2并伸至快接外壳4-1内腔，倒扣4-7可防止水管3从导套4-2滑脱，当拉动水管3的力越大，倒扣4-7对水管3的抓力越大，水管3越难脱离。90°弯接头7也采用相同的装配方式与快速接头组件4的导套4-2相连。
为了保证该流量计的密封性，在水管3外圆与快接外壳4-1内腔壁之间、90°弯接头7外圆与快接外壳4-1内腔壁之间均设有水管密封圈4-3，在外螺纹接头4-5外圆设有流量计密封圈4-4。
如图4和7所示，所述快接外壳4-1内腔与外螺纹接头4-5内孔之间设有环形凸起部a4-8，外螺纹接头4-5内孔设有盐路分流器，盐路分流器包括分流套6-3和橡胶垫圈6-2，分流套6-3通过过盈配合的方式固定在外螺纹接头4-5内孔壁上，分流套6-3一端贴紧环形凸起部a4-8，分流套6-3另一端设有环形凸起部b6-10，环形凸起部b6-10与环形凸起部a4-8之间形成环形槽，橡胶垫圈6-2设置在环形槽内，橡胶垫圈6-2外圆与分流套6-3之间、橡胶垫圈6-2两侧与环形凸起部a4-8、环形凸起部b6-10之间均留有间隙。
橡胶垫圈6-2的是橡胶材质，中间有一个圆孔。橡胶垫圈6-2可在环形槽内沿轴向和外径向活动，当有水流经过，橡胶垫圈6-2受推力向叶轮6-7运动，压到环形凸起部b6-10上起到密封作用，使水流只能从中间圆孔经过，可通过橡胶垫圈6-2的孔径控制流量计的最大流速。
如图10和11所示，所述流量计支架8用于支撑流量计外壳6-1。本实施例中，所述流量计外壳6-1底部设有支撑座6-11，支撑座6-11沿纵向开设有支架卡槽，流量计支架8下端固定，流量计支架8上端卡入支架卡槽内，在流量计支架8上沿纵向开设有调节槽8-1，调节槽8-1底部沿水平方向开设有贯穿流量计支架8和支撑座6-11的通孔，螺钉8-2穿入通孔内并通过螺母8-3锁紧。松开螺母8-3后，流量计支架8上端与支撑座6-11沿支架卡槽上下滑动，便于调节支撑流量计外壳6-1的高度。
该流量计的装配步骤如下：
流量计主体部分装配：将刚玉6-5装进衬套6-6，衬套6-6装入流量计分流器6-4内圈，将其中一个流量计分流器6-4塞入流量计外壳6-1内，将叶轮6-7中心轴一端装入流量计分流器6-4内圈衬套6-6中，再将另一个流量计分流器6-4塞入流量计外壳6-1内，并将叶轮6-7中心轴另一端装入流量计分流器6-4内圈衬套6-6中；
快速接头组件4装配：将水管密封圈4-3装入快接外壳4-1内腔，将导套4-2塞入，将流量计密封圈4-4套在外螺纹接头4-5外圆，再将盐路分流器塞入外螺纹接头4-5内 孔，
总装配：将两个快速接头组件4的外螺纹接头4-5与流量计外壳6-1内腔两端端内螺口配合旋紧；再将水管3插入快速接头组件4的导套4-2内，将流量计外壳6-1固定在流量计支架8上，将90°弯接头7插入快速接头组件4的导套4-2内，90°弯接头7通过外接管路连接软水设备控制阀的吸盐口。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
