Description

回流调节阀装置及净水系统 技术领域
本发明涉及水净化技术领域，尤其涉及一种回流调节阀装置及净水系统。
 背景技术
在净水系统中，滤膜件内的浓水侧的浓水经过换向阀分成两路，一路作为废水而排出，另一路与自来水混合后重新供入滤膜件以重新参与制备直饮水。
为使自来水与浓水混合的设备实现集约化的目的，现有技术中，利用三通连接自来水管与回水管路，来自自来水管的自来水与来自回水管路的浓水进入到三通，然后从三通的出水端口流出而供入滤膜件。
然而，使自来水与浓水在三通内混合却存在混合过程冲击较大且混合不均匀的缺陷，为此，专利号为202022735312.0的中国专利提供了一种净水系统的阀装置，如该专利申请文件的附图说明中的图1所示，该阀装置通过在阀体10的阀腔中设置阀芯311、弹簧312、阀芯321、阀芯33、阻尼部件41、阻尼部件42有效缓解了自来水和浓水的在混合过程中的冲击，且通过设置具有混水腔的混水部件60而使得自来水与浓水能够获得充分均匀混合。
然而，该阀装置中阀芯33和阀芯321的位置基于进入阀体内自来水与进入阀体内浓水的压力差决定，而该压力差不稳定，尤其是因为自来水的压力不稳定而导致压力差不稳定，这导致阀芯33和阀芯321的位置不稳定，进而导致进入阀体内以用于进行混合的浓水和自来水的流量不稳定，而浓水流量的不稳定会使阀装置出现较差的使用效果，例如，影响换向阀对浓水的分配比例（所需重新利用的浓水与作为废水的浓水的分配比例），再例如，当自来水的压力较大时，阀芯33所控制的开度变小，进入阀体内的浓水的流量变小，阀装置与换向阀之间的节流压力变大，这影响滤膜件中的浓水侧的浓水流速，使滤膜件内部极差化严重，且浓水的利用率降低。
为解决上述问题，专利号为202110758883.2的中国专利提供一种混水阀装置及净水系统，该装置能够主动控制浓水的流量，并基于对浓水流量的控制在一定程度上影响自来水的流量，进而在一定程度能够控制自来水与浓水的混合比例。
然而，上述的混水阀装置调节自来水与浓水的混合比例的效果仍不佳，受到自来水压力及压力波动影响很大，例如，若来自自来水管的自来水的压力增大，如该专利的说明书附图的图1所示的第一阀芯势必朝开度增大的方向移动，而这种移动无法被及时阻止，进而导致自来水的流量增大，另外，不但使自来水的流量增大，并且由于电机所驱动的第二阀芯并不能及时的响应自来水的流量的增大而使浓水的流量相应增大，进而导致自来水与浓水的混合比例平衡被打破，另外，自来水的压力的变化还会导致滤膜件的内的压力变化，不利于滤膜件的制水、使用寿命，且增加了对水质的监控困难。

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。
本发明的实施例提供了一种回流调节阀装置，该回流调节阀装置用于调节自来水与重新参与制水的浓水的混合比例，并用于将自来水和浓水进行混合，经由该回流调节阀装置混合后的混合水直接或者借由增压泵供入净水系统中的滤膜件的浓水侧的进入端以用于制水。
如图1至图5所示，该回流调节阀装置包括：第一调节阀10、第二调节阀20以及混水部件30；第一调节阀10内部围成自来水流道，自来水在经过第一调节阀10的内部的自来水流道过程中，第一调节阀10通过限定自来水流道的通流截面而控制自来水的流量；第二调节阀20内部围成浓水流道，用于重新参与制水的浓水在经过第二调节阀20的内部的浓水流道过程中，第二调节阀20通过限定浓水流道的通流截面而控制浓水的流量。被控制流量后的自来水与浓水进入到混水部件30中进行混合。
在本发明中，如图2并结合图1所示，第一调节阀10包括第一阀体11和第一阀芯131机构13；第一阀体11大致呈柱状，第一阀体11内形成有第一阀腔，在第一阀腔中形成有阀座133，且在第一阀腔中装设有活塞座135，阀座133与活塞座135轴向间隔排布；阀座133与活塞座135之间限定出过流腔122，阀座133与第一阀体11的其中一端之间限定出缓冲腔121，活塞座135与第一阀体11的另一端之间限定出压力腔123；第一阀体11具有自来水进水口111、自来水出水口112，自来水进水口111形成于第一阀体11靠近缓冲腔121的端部，自来水出水口112与过流腔122对应且与过流腔122连通；阀座133上开设有阀孔132，该阀孔132用于使缓冲腔121与过流腔122连通，该阀孔132的孔壁形成有锥面1321，活塞座135上开设有轴向贯通的活塞腔1351。
第一阀芯131机构13包括第一阀芯131、活塞134、活塞杆、缓冲阀芯137、第一弹簧136、第二弹簧138。第一阀芯131伸入至阀孔132中，活塞134位于活塞座135的活塞腔1351中，活塞杆连接第一阀芯131与活塞134，这使得第一阀芯131与活塞134同步联动，第一弹簧136用于朝阀孔132方向阀芯推抵活塞134，这使得第一阀芯131对阀孔132具有关闭趋势；缓冲腔121中设置有多个第一分水格栅14，该第一分水格栅14周向布置以围成一个孔洞，缓冲阀芯137位于孔洞中以朝向自来水进水口111，第二弹簧138用于朝自来水进水口111方向推抵缓冲阀芯137。如此，从自来水进水口111进入第一阀体11的自来水迫使缓冲阀芯137打开，该缓冲阀芯137以及第一分水格栅14在一定程度上缓冲自来水的压力波动，进入到缓冲腔121的自来水使得第一阀芯131轴向朝第一弹簧136方向移动，进而使得第一阀芯131与阀孔132的锥面1321共同限定阀孔132的开度，此处为影响自来水流道的通流截面的位置，在第一弹簧136的作用下，第一阀芯131与阀孔132限定了自来水流道的通流截面，进而控制着自来水的流量，进入过流腔122并被限定流量后的自来水经过自来水出水口112流入到混水部件30中。
如图1所示，第二调节阀20包括：第二阀体21和第二阀芯机构23；第二阀体21与第一阀体11彼此的独立设置，且第二阀芯机构23仅用于限定浓水流道的通流截面，即仅用于控制浓水的流量，而不与第一阀芯131机构13进行机械连接以及力和运动的相互作用。第二阀芯机构23与第一阀芯131机构13彼此独立的控制自来水的流量和浓水的流量。
混水部件30内形成柱状腔31，混水部件30具有自来水入水通道321、浓水入水通道322以及混合水出水口323；第一调节阀10的第一阀体11的自来水出水口112（被控制流量后的自来水）连接至自来水入水通道321，第二调节阀20的第二阀体21的浓水出水口212（被控制流量后的浓水）连接至浓水入水通道322；自来水入水通道321以及浓水入水通道322均切向的延伸至柱状腔31。
本发明的关键在于：活塞座135与第一阀体11的端部限定出了上述的压力腔123，并且在柱状腔31与压力腔123之间建立连通柱状腔31边部区域与压力腔123的压力反馈通道113。当来自自来水管的自来水的压力增大时，经过第一调节阀10而进入柱状腔31的自来水的流速增加，这使得混合水在柱状腔31内作圆周运行的速度增加，由于混合水做圆周运动，柱状腔31的中部区域的水压小于边部区域的水压，且随着水流速度的增大，边缘区域的水压增加程度大，该增大的水也借由压力反馈通道113传递至压力腔123以及活塞腔1351，进而使得该压力推抵活塞134以带动第一阀芯131朝阀孔132开度较小方向的移动，进而抑制因压力提高而带来的自来水流量的增加以及混合水压力的增大。
本发明通过在第一调节阀10中构造压力腔123，并通过在压力腔123与柱状腔31的边部区域之间建立压力反馈通道113，进而依靠自来水自身压力反馈而及时的抑制自来水的流量增大和压力波动，不但能够有效维持自来水与浓水的混合比例平衡，还能够降低压力波动，且对滤膜件的制水、使用寿命以及对水质的监控均有利。
 本发明的实施方式
如图1和图2所示，在一些优选实施例中，在压力腔123内设置有多个第二分水格栅15，多个第二分水格栅15周向排布，该第二分隔格栅支撑于压力腔123以至少用于限制活塞座135窜动，使活塞座135始终处于装配位。
在一些优选实施例中，如图3、4并结合图1所示，第二调节阀20的第二阀体21内具有第二阀腔，第二调节阀20的第二阀芯机构23包括：固定盘231、转动盘232、伺服电机234以及转杆233。固定盘231设置于第二阀腔内并将第二阀腔分隔成第一子腔室221和第二子腔室222；第二阀体21的浓水进水口211位于靠近第一子腔室221的端部，第二阀体21的浓水出水口212与第二子腔室222对应并与第二子腔室222贯通；转动盘232位于第二子腔室222内并贴靠固定盘231。
在固定盘231上开设多个导流孔2311（或者在转动盘232上开设多个导流孔2311），多个导流孔2311的截面大小顺序变化，转动盘232上形成有镂空部2321（或者在固定盘231上形成镂空部2321），通过转动转动盘232而使镂空部2321与不同截面的导流孔2311相对（此处为影响浓水流道的通流截面的位置），以使得第一子腔室221与第二子腔室222通过镂空部2321所对应的导流孔2311连通。如此，浓水经过浓水进水口211进入到第一子腔室221，并通过镂空部2321所对应的导流孔2311进入到第二子腔室222，借由使不同的导流孔2311连通第一子腔室221与第二子腔室222而限定浓水流道的通流截面，进而限定浓水的流量，进入第二子腔室222的浓水通过浓水出水口212进入到混水部件30中以与亦进入到混水部件30中的自来水在柱状腔31内作圆周运动以实施混合，所混合后的混合水借由净水系统中的增压泵而进入到滤膜件的浓水侧的进水端以进行制水。
在一些优选实施例中，如图5并结合图1所示，混水部件30中的柱状腔31内设置有第一分隔板33和第二分隔板34，第一分隔板33将柱状腔31分成第一子柱状腔311和第二子柱状腔312，自来水入水通道321以及浓水入水通道322均切向的延伸至第一子柱状腔311并与第一子柱状腔311连通，压力反馈通道113连接至第一子柱状腔311的边部区域，如此，压力腔123内的压力由第一子柱状腔311的边部区域的压力反馈。第一分隔板33的中部具有开口331，第二分隔板34设置于第二子柱状腔312中，该第二分隔板34的边部具有开口341，进入到第一柱状腔31并获得混合的混合水经过第一分隔板33的中部的开口331而进入到第二子柱状腔312，并从第二分隔板34的边部的开口341流出，以最终从形成于柱状腔31远端的混合水出水口323流出。在本实施例中，通过将柱状腔31分隔成第一子柱状腔311和第二子柱状腔312，进而使得压力腔123的压力仅由第一子柱状腔311的边部区域反馈，而进入到第二子柱状腔312内的混合水较少的受到第一子柱状腔311内的压力波动的影响，即，第二子柱状腔312内的混合水的压力波动很小，进而使得滤膜件的浓水侧内的压力波动很小。
本发明还公开了一种净水系统，包括上述的回流调节阀装置。
