Description

浓水调节阀 技术领域
本发明涉及水净化技术领域，尤其涉及一种浓水调节阀。
 背景技术
净水系统（用于将如自来水之类的原始水处理成符合人体饮用标准的饮用水）中会连接有浓水调节阀，该浓水调节阀用于接收来自净水系统的浓水，并将浓水按比例分配以使得一部分浓水重新回到净水系统而参与利用，而使另一部分浓水排放。
现有技术中的浓水调节阀的内部形成有孔系，通过阀芯来控制孔系的开度进而调节浓水的分配比例。
然而，由于进入浓水调节阀中的浓水容易结垢，进而容易阻塞孔系中的孔，尤其容易阻塞孔的端部，如，最小孔径的孔的端部，进而导致浓水调节阀的浓水分配比例的规律发生改变，甚至使整个浓水调节阀发生阻塞，最终会影响净水系统的运行以及饮用水的水质。

为了保持本发明实施例的以下说明清楚且简明，本发明省略了已知功能和已知部件的详细说明。
本发明的实施例公开了一种浓水调节阀，该浓水调节阀连接至净水系统中以用于将从净水系统流出的浓水按比例分配，使得经过浓水调节阀的浓水一部分再次回流净水系统以参与饮用水的制备，而另一部分直接排出。
如图1至3所示，该浓水调节阀包括：阀体10、分隔部件、阀芯40以及驱动机构。
阀体10的内部形成阀腔，阀体10的一端敞口，分隔部件从敞口侧装入阀腔中，该敞口侧借由端盖13封堵。分隔部件将阀腔分成第一腔11（第一腔11位于图1所示的分隔部件的左侧）以及第二腔12（第二腔12位于图1所示的分隔部件的右侧）。
分隔部件上开设有孔系50，该孔系50的两端分别贯通至第一腔11和第二腔12；阀芯40设置于第二腔12中，通过转动阀芯40而改变孔系50的通流截面。
阀体10上与第一腔11对应的轴向位置形成有进水口21和出水口22，进水口21和出水口22均与第一腔11连通；阀体10上与第二腔12对应的轴向位置形成有排水口，该排水口与第二腔12连通。
进水口21用于与净水系统的浓水出水口22连通，出水口22用于与净水系统的浓水回水口连通。如此，从净水系统流出的浓水经由进水口21进入第一腔11中，进入第一腔11中的浓水一分部通过出水口22并经过净水系统的浓水回水口重新回流于净水系统以参与饮用水的制备，而另一部分经过孔系50而进入第二腔12，并经过排水口排出。并且，通过驱动机构驱动阀芯40转动而调节孔系50的通流截面，进而能够调节经过孔系50的浓水的流量，进而能够改变从出水口22排出的浓水与从排水口排出的浓水的比例。
本实施例的关键在于：将第一腔11设置成扁柱状腔，即，第一腔11的内壁围成一个扁圆柱面，重要的是：使进水口21沿切线方向延伸至第一腔11。
第一腔11和进水口21的上述结构特点使得：
浓水借由进水口21进入第一腔11后，浓水以一定的流速在第一腔11内进行旋转流动，这种旋转流动使得浓水在第一腔11内能量（动能）损失小，进而使得第一腔11的内壁以及分隔部件的朝向第一腔11的端面持续的被旋转流动的浓水冲刷，进而能够有效避免浓水在第一腔11的内壁和分隔部件的端面结晶，尤其能够更大程度的避免孔系50的端部结晶。
另外，浓水的旋转流动所产生的切向力对孔系50内部也就有较大的冲洗作用。
另外，浓水因在第一腔11中做旋转流动，进而延长了浓水在第一腔11中的时间，因而充分利用了单位量的浓水对第一腔11内相关表面的冲刷作用。
基于上述可知，本实施例所提供的浓水调节阀的优势在于：
通过使进水口21沿切线方向延伸至第一腔11，进而使孔系50获得持续的很大程度的冲刷，进而能够有效防止孔系50因结晶而阻塞，尤其能够有效防止孔系50中孔口较小处的端部阻塞。
在一些更为优选的实施例中，如图2所示，使出水口22也沿切线方向延伸至第一腔11，但是，使出水口22的朝向与第一腔11内的做旋转流动的浓水的飞离方向相反。如此设置的优势在于：假若进水口21的延伸方向与第一腔11内的做旋转流动的浓水的飞离方向相同或者与飞离方向成一定角度，此时，做旋转流动的浓水在经过出水口22时会受到较大的剪切力，进而导致浓水流动发生紊乱，且造成较大的能量损失。而通过使进水口21的朝向与做旋转流动的浓水的分离方向相反，使得浓水在经过进水口21时受到的阻力（包括剪切力）很小，能量损失很小，这使得浓水在一定程度上持续的在第一腔11中做旋转流动，进一步提高了浓水对第一腔11内的各腔壁的冲刷作用。
在一些更为优选的实施例中，使出水口22的朝向与进水口21的朝向相反。即，进水口21位于图2所示的顶部，而出水口22位于图1所示的底部。这样使得所有进入第一腔11中的浓水均至少通过半个圆弧的流动行程，进而更大程度的减少了浓水的能量损失。
孔系50可以具有多种结构形式，下面列举孔系50的两个具体结构形式：
第一种结构形式（附图中未示出）：孔系50包括贯通分隔部件的多个通孔，该多个通孔周向排布且孔径顺序变化，对应地，阀芯40通过使不同孔径的通孔打开而其余通孔关闭而改变孔系50的通流截面，进而改变从出水口22和排放口23流出的浓水的比例。
第二种结构形式：如图2所示，该孔系50为沿周向延伸且截面渐变的弧形通槽。阀芯40通过使弧形通槽的不同区域段打开而其他区域段关闭而改变孔系50的通流截面，进而改变从出水口22与排放口23流出的浓水的比例。
在一些更为优选的实施例中，进水口21以及出水口22在连通第一腔11的区域段均形成收缩口211。如此设置的优势在于：通过设置收缩口211来增加进入第一腔11中的浓水的流速，进而提高浓水对第一腔11各腔壁的冲刷作用。
分隔部件具有多种结构形成，在一些更为优选的实施例中，分隔部件为套状部件30，该套状部件30在位于第一腔11的一端形成阀盘31；孔系50开设在该阀盘31上；阀芯40装设于套状部件30中，该阀芯40可由陶瓷材料制成；套状部件30借由密封圈与阀体10进行密封设置，且可通过键结构或过盈配合限制套状部件30转动；套状部件30内装设有套用挡圈，该套用挡圈用于限制阀芯40从套状部件30中脱出。将分隔部件的结构设置成套状部件30以及使阀芯40与套状部件30形成上述的装配关系的优势在于：可更大程度的提高装配的紧凑性。
在一些更为优选的实施例中，第二腔12设置成柱状腔，第二腔12与第一腔11之间限定出阶梯结构；套状部件30的外周形成有环形阶梯以用于与阶梯结构配合。如此，方便套状部件30的装配以及定位。
阀盘31朝向第一腔11的表面可以是平面，也可以是中部具有隆起部311的表面。当阀盘31的表面的中部设置有隆起部311时，孔系50布置在隆起部311的径向上的外围。如此，浓水中的大部分沿隆起部311的径向上的外围旋转流动，进而能够提高浓水的流速，对孔系50具有更佳的冲洗作用。
流经孔系50的浓水可以借助多种结构形式流向第二腔12，在一些更为优选的实施例中，如图1至图3所示，阀芯40朝向阀盘31的端面的外缘处开设有一个端槽41；端槽41与第二腔12之间形成有引导通道，该引导通道包括开设于阀芯40的外周面上的环形导流槽42以及开设于套状部件30上的导流通道32。端槽41轴向的延伸以贯通至环形导流槽42；导流通道32的一端贯通至套状部件30的内壁并与环形导流槽42轴向相对，而导流通道32的另一端贯通至套状部件30位于第二腔12的端面。如此，流经孔系50的浓水依次经过端槽41、环形导流槽42以及导流通道32而进入第二腔12，并经排放口23排出。并且，通过转动阀芯40而能够改变端槽41与孔系50的重叠面积，进而改变限定浓水流量的通流截面。
在一些更为优选的实施例中，使端槽41的截面面积大于与端面对应的孔系50的截面面积，这使得流经孔系50的浓水在进入端槽41后流速减缓，这势必降低了浓水对相关部件的冲击，进而能够减小噪音和振动。
在一些更为优选的实施例中，导流通道32靠近第二腔12的一段形成喇叭口。这也使得流经导流通道32的浓水的流速减缓，进而在一定程度上减小噪音和振动。
驱动机构可以通过多种方式驱动阀芯40，例如，驱动机构可以借由伺服电机驱动阀芯40。
在一个优选实施例中，如图1所示，选用旋钮63机构60作为驱动机构。该旋钮63机构60包括轴系和旋钮63。轴系包括挡位柱61和轴杆62。具体地，挡位柱61的头部通过花键而连接至阀芯40，挡位柱61的外周与端盖13之间设置有弹簧顶珠64；轴杆62的头部穿设端盖13而连接至挡位柱61的尾部，轴杆62与端盖13之间设置有两道密封圈；旋钮63连接至轴杆62的尾部。如此，通过旋拧旋钮63而能够驱动阀芯40转动。
