本申请提出一种软水阀。
在本申请实施例中,如图1至图4所示,该软水阀包括阀体10、多路阀20、吸盐注水阀30及驱动机构40,所述吸盐注水阀30包括第一阀杆31,所述驱动机构40包括安装座41及凸轮42,所述第一阀杆31伸出所述阀体10的一端与所述凸轮42传动配合,所述安装座41上设有滑接结构411,所述第一阀杆31的外端与所述滑接结构411沿纵向方向可滑动配合,且所述第一阀杆31的外端在横向方向上与所述滑接结构411限位配合;所述纵向方向与所述第一阀杆31的长度方向一致,所述横向方向垂直于所述纵向方向及所述凸轮42的轴向方向。
在本实施例中,第一阀杆31的外端即为第一阀杆31伸出阀体10的一端,第一阀杆31的外端与凸轮42的传动配合,既可以是在凸轮42上设置偏心的环形槽而在第一阀杆31上设置于该环形槽滑动配合的凸起,也可以是在凸轮42上设置偏心的凸起而在第一阀杆31上设置于该凸起滑动配合的条形槽。多路阀20用以实现阀体10内不同水路的切换,吸盐注水阀30用以配合多路阀20在软水阀吸盐或注水的过程中开启注水或结束注水。具体地,第一阀杆31伸入阀体10的一端与注水活塞连接,第一阀杆31做直线往复运动而带动注水活塞在注水开启位或注水闭合位停留。与凸轮42和第一阀杆31之间的配合相似,安装座41上的滑接结构411可以为槽道,而第一阀杆31可直接与该槽道配合,也可通过凸设凸起与该槽道配合;与之相反,若滑接结构411为凸起,则第一阀杆31可开设与该凸起配合的槽道。
可以理解的是,在凸轮42的旋转运动转换为第一阀杆31的直线运动时,除了产生将第一阀杆31往外拉出阀体10或将第一阀杆31压入阀体10的力之外,还会产生使第一阀杆31沿横向方向摆动的力。在现有技术的软水阀结构中,这种摆动力直接被传递至第一阀杆31与阀体10之间的滑动副。而在本申请中,滑接结构411与第一阀杆31在横向方向的限位配合可以抵消这种摆动力,大大地减小了传递至第一阀杆31与阀体10配合的部位的摆动力。
本申请软水阀通过在安装座41上设置与第一阀杆31在纵向方向可滑动配合并在横向方向限位配合的滑接结构411,以形成双重导向结构,由此,凸轮42的的旋转运动转换为第一阀杆31的直线运动时,滑接结构411可以在横向方向上限制第一阀杆31摆动,并分担了第一阀杆31沿横向方向作用于阀体10上的压应力,进而一方面可以减小第一阀杆31与阀体10之间滑动副结构磨损,松动的风险,另一方面使得第一阀杆31的运动更为平稳。
进一步地,如图7和图8所示,所述滑接结构411具有在横向方向上相对的两导轨面412,所述第一阀杆31的外端伸入两所述导轨面412之间并分别与两所述导轨面412沿所述纵向方向可滑动配合。在本实施例中,两导轨面412之间形成滑道,第一阀杆31可直接通过外周面与该滑道滑动配合,也可成形有用于与该滑道配合的滑动配合结构。
需要说明的是,若与第一阀杆31配合的两限位面在横向方向上相背,即该滑接结构411为凸起,则需在第一阀杆31上直接或间接开设与该凸起配合的滑道,且该滑道需要在纵向方向上延伸一定长度以满足第一阀杆31的运动距离,若滑道较窄,则凸起的厚度相应地较小,容易损坏;若滑道较宽,则会减弱第一阀杆31本身的结构强度或使第一阀杆31的结构更复杂而不紧凑。因此,与该方案相比,具有在横向方向上相对的两导轨面412的滑接结构411与第一阀杆31的配合更加简单紧凑,且强度更高。
进一步地,如图5和图6所示,所述第一阀杆31的外端成形有与所述滑接结构411可滑动配合的滑动配合部311,所述滑动配合部311具有凸出于所述第一阀杆31的外周面并分别与两所述导轨面412可滑动配合的两滑接面312。在本实施例中,两滑接面312的面积可选小于两导轨面412,以减小滑动摩擦力,进而减少对第一阀杆31运动的阻碍。通过在第一阀杆31的外端设置滑动配合部311,减少了第一阀杆31与两导轨面412的整体接触面积,从而减少摩擦阻力;同时还保证滑动配合部311与两导轨面412的有效接触面积,保持滑接结构411与滑动配合部311限位配合的稳定性。
进一步地,如图6和图8所示,所述滑动配合部311还具有连接两所述滑接面312并朝向所述凸轮42的传动面313,所述传动面313上凸设有传动轴314,所述凸轮42设有与所述传动轴314适配的传动槽421。在本实施例中,传动槽421即为偏心的环形槽,传动轴314与传动槽421配合以将凸轮42的旋转运动转换为第一阀杆31沿纵向方向的直线运动。通过将传动轴314设置在第一阀杆31的滑动配合部311上,有效利用了滑动配合部311,使得第一阀杆31的整体结构更加简单紧凑;同时第一阀杆31用于滑动配合的结构与用于在横向方向上限位配合的结构设置在相邻位置,能最大程度地限制第一阀杆31在横向方向上的摆动,一方面使得第一阀杆31的运动更加平稳,另一方面进一步减少了传递至第一阀杆31与阀体10配合部位的压应力。
进一步地,如图4、图7及图8所示,所述安装座41包括第一安装板413,所述第一安装板413朝向所述凸轮42的一面凹设有在所述纵向方向延伸的滑槽414,两所述导轨面412分别位于所述滑槽414的两相对内壁面上,所述滑动配合部311与所述滑槽414可滑动配合。
在本实施例中,滑槽414延伸至贯通第一安装板413邻近阀体10的侧边,两导轨面412位于滑槽414横向方向上相对的两内壁面上,可以理解的是,滑槽414在纵向方向上的延伸长度应满足第一阀杆31的外端离阀体10最远的极限位置。在实际应用中,安装座41还包括与第一安装板413相对的盖板,第一安装板413用于与盖板共同限制出供凸轮42安装的第一安装腔(图未示)。通过直接在第一安装板413上开设滑槽414,使得滑接结构411更加简单紧凑,生产加工更加简便。
进一步地,如图4所示,所述滑槽414包括与所述凸轮42相对的底壁415,所述底壁415开设有沿所述纵向方向延伸的观察孔416,且所述底壁415在所述观察孔416的所述横向方向上的至少一侧设有指示刻度417。在本实施例中,观察孔416用于供用户观察滑动配合部311的实时位置,从而了解位于阀体10内的注水活塞的实际位置。指示刻度417用于方便用户更直观地了解位于阀体10内的注水活塞的实际位置。指示刻度417可选凸设于底壁415背向凸轮42的一面,并可选设置于观察孔416横向方向上的两侧,以使指示刻度417更加明显,便于观察。
进一步地,所述传动面313与所述第一阀杆31朝向所述凸轮42的一侧平齐并邻近所述凸轮42,所述滑接面312朝远离所述凸轮42的方向延伸。
在本实施例中,在理想状态下,传动面313应无限接近凸轮42并保持与第一阀杆31朝向凸轮42的一侧平齐,以使第一阀杆31也相应地能无限接近凸轮42,由此能有效减少第一阀杆31与凸轮42的传动力矩,减少传动过程中的动力损失。当第一阀杆31距离凸轮42较近时,由于滑动配合部311需要与开设于第一安装板413上的滑槽414配合,若第一安装板413也随之靠近凸轮42,则第一安装板413上的固定结构会对凸轮42的转动造成阻碍,因此第一安装板413应与凸轮42保持一定距离;而滑接面312需要与导轨面412保持足够接触面积,因此滑接面312应朝靠近第一安装板413的方向,具体而言是靠近滑槽414的方向延伸并凸出于第一阀杆31朝向第一安装板413的一侧,以与导轨面412有效配合。
进一步地,如图6所示,所述第一阀杆31包括杆部315,所述滑动配合部311包括呈中空设置并设于所述杆部315末端的滑块316,所述杆部315的末端伸入滑块316的内腔并与所述滑块316连接,所述滑块316朝向所述底壁415的一面开设有与所述观察孔416对应的透孔317。在本实施例中,若滑块316在纵向方向上的尺寸大于观察孔416,则当第一阀杆31运动幅度过小时,通过观察孔416无法准确判断注水活塞的具体位置,因此呈中空设置的滑块316及开设于滑块316上的透孔317能使用户观察到位于滑块316内的杆部315的末端,以使通过杆部315的末端的位置判断出的注水活塞的位置更加真实有效。
进一步地,如图5所示,所述多路阀20包括第二阀杆21,所述驱动机构40还包括主动轮44及传动轮43,所述主动轮44与所述第二阀杆21的外端传动配合,所述传动轮43传动连接所述主动轮44与凸轮42,以使所述第一阀杆31与第二阀杆21形成联动运动。在本实施例中,主动轮44与第二阀杆21传动配合,以将主动轮44的旋转运动转换为第二阀杆21的直线运动,而主动轮44与凸轮42联动运动,进而使第一阀杆31与第二阀杆21联动运动,实现了在软水阀吸盐或注释的过程中多路阀20与吸盐注水阀30在阀体10内相应位置的密切配合。在实际应用中,驱动机构40还包括用于提供动力源的减速机组,减速机组的输出轴与主动轮44传动连接,并通过传动轮43带动凸轮42,以使主动轮44与凸轮42共用一个动力源。
本申请还提出一种软水机,该软水机包括一种软水阀,该软水阀的具体结构参照上述实施例,由于本软水机采用了上述所有实施例的全部技术方案,因此至少具有上述实施例的技术方案所带来的所有技术效果,在此不再一一赘述。
本申请提出一种软水阀。
在本申请实施例中,如图9至图14所示,该软水阀包括:
阀体10,具有过水通道11及连通于所述过水通道11一端的过水口12,所述阀体10上开设有贯穿所述过水通道11的侧壁并邻近所述过水口12的插接口13;
过水接头20,插接于所述过水口12,所述过水接头20两端贯通并与所述过水通道11连通;以及
固定件30,插接于所述插接口13内,并卡接于所述过水接头20的位于所述过水通道11内的部分,以至少在所述过水接头20的轴向上限位所述过水接头20。
在本实施例中,过水通道11通常包括进水通道111及出水通道112,进水通道111用于供未处理的水进入软水阀进行离子交换,出水通道112用于供水质改善后的水流出软水阀以供用户使用。过水接头20用以连接外接管路与过水通道11,过水接头20插接于过水口12,外接管路的水通过过水接头20从过水口12进出过水通道11。插接口13贯穿过水通道11的侧壁,用以供固定件30插接。固定件30从插接口13沿垂直于过水通道11轴向的方向伸入过水通道11内并卡接于过水接头20,以至少使过水接头20在其轴向上限位固定。
需要说明的是,过水接头20在固定件30远离过水口12的一侧的部位应与过水通道11的侧壁密封配合,具体地,过水接头20在过水通道11内的末端的外周壁开设有沿周向延伸的密封槽,密封槽内设置有密封圈,以防止过水通道11与过水接头20的配合处漏水。固定件30相对于密封圈及密封槽更靠近过水口12,以有效密封过水接头20与过水通道11。可以理解的是,固定件30还可在周向上限位过水接头20,以避免过水接头20转动对密封圈造成磨损。
本申请软水阀在过水通道11的侧壁开设邻近过水口12的插接口13,并通过插接于插接口13的固定件30对插接于过水口12的过水接头20限位卡接,使过水接头20固定连接于过水口12;即通过插接口13与固定件30来实现过水接头20与阀体10的过水口12的固定连接,从而使得过水接头20与阀体10的连接结构更加简单,生产加工更加方便。
进一步地,如图9至图14所示,所述固定件30包括插针31,所述插针31通过所述插接口13伸入所述过水通道11,并卡接于所述过水接头20的外周壁。在本实施例中,插针31沿垂直于过水通道11轴向的方向延伸,插接口13与插针31可滑动配合。插针31与过水接头20的外周壁可通过相适配的卡接结构卡接,举例而言,插针31上设置卡勾,过水接头20的外周壁设置对应的卡环;或者插针31上设置嵌槽,过水接头20的外周壁设置对应的嵌台;还可由插针31本身与过水接头20上的卡接结构卡接;只需满足插针31与过水接头20的外周壁卡接即可。插针31的一端可抵接于插接口13的边缘,以对过水接头20形成相应的卡接力。通过插针31来卡接过水接头20,使得固定件30的结构更加简单,从而插接口13的形状也更加简单,更便于软水阀的生产加工。
进一步地,如图9至图14所示,所述固定件30还包括位于所述插接口13外侧的连接板32,所述插针31连接于所述连接板32一侧边,所述插针31的数量为两个并沿所述连接板32的侧边间隔设置,两所述插针31分别卡接于所述过水接头20的外周壁上两相背离的部位。在本实施例中,插针31的厚度可选与连接板32的厚度相同。连接板32沿垂直于轴向的方向延伸并抵接于阀体10,插接口13的数量与插针31对应。两插针31分别卡接于过水接头20的外周壁两相背离的位置,以进一步提高对过水接头20卡接的稳固性,同时还能将过水接头20夹固于两插针31之间,以从周向上限位过水接头20,避免过水接头20转动。
进一步地,如图9和图10所示,所述过水接头20的外周壁开设有卡槽21,所述插针31卡接于所述卡槽21。在本实施例中,卡槽21可选沿过水接头20的周向延伸,以使过水接头20不需要通过旋转定位便可使插针31卡接于卡槽21,使得插针31与过水接头20之间的卡接更加简单方便。插针31自身卡接于卡槽21,使得固定件30的结构更加简单,便于加工。在实际应用中,连接板32与插针31连接的侧边可选设置成与所抵接的阀体10部位相适应的形状,以使软水阀的整体结构更加紧凑。
进一步地,如图9至图14所示,所述连接板32的两端分别凸出于两所述插针31的外侧边。在本实施例中,连接板32的两端分别凸出于邻近的插针31的边缘,以形成抓柄,便于安装与拆卸过水接头20的过程中对固定件30的抓取。
进一步地,如图9和图10所示,所述阀体10上还开设有贯穿所述过水通道11的侧壁的卡接口14,所述卡接口14远离所述插接口13,所述插针31的自由端卡接于所述卡接口14。在本实施例中,卡接口14可选位于插接口13的垂直于轴向的方向上,以使插针31的穿插方向更加简单合理。插针31的自由端卡接于卡接口14,插针31的固定端卡接于插接口13,增加了插针31与阀体10的接触面积,使得过水接头20及阀体10对插针31的作用力更加分散,从而提高了插针31的稳定性,同时也使对过水接头20的卡接更加稳固。
进一步地,如图9至图12所示,所述阀体10还凸设有邻近所述插接口13的凸台15,所述凸台15开设有卡孔151,所述连接板32凸设有与所述卡孔151适配的卡凸321。在本实施例中,凸台15可选凸设于插接口13与过水口12之间,以对固定件30形成有效保护,防止固定件30在软水阀使用过程中被碰损。凸台15可选沿连接板32的长度方向延伸并与连接板32相对。固定件30对过水接头20卡接到位后,连接板32上的卡凸321卡接于凸台15的卡孔151,以实现固定件30与阀体10的连接,从而使固定件30对过水接头20的卡接更加稳固。卡凸321的数量可选为两个并沿连接板32的长度方向间隔设置,卡孔151的数量及位置与卡凸321相对应,以提高固定件30与阀体10连接的稳定性。
进一步地,如图13和图14所示,所述连接板32朝向或背离所述凸台15的部位均凸设有所述卡凸321。在本实施例中,连接板32的两相背面均凸设有卡凸321,从而在装配固定件30时不需要过多翻转是卡凸321对准卡孔151,从而使得软水阀在整体装配过程中更加简单方便,提高了装配效率。
本申请还提出一种水处理设备,该水处理设备包括离子交换罐及一种软水阀,该软水阀的具体结构参照上述实施例,由于本水处理设备采用了上述所有实施例的全部技术方案,因此至少具有上述实施例的技术方案所带来的所有技术效果,在此不再一一赘述。其中所述软水阀安装于所述离子交换罐以使所述阀体10的内腔与所述离子交换罐的内腔连通。
本申请提出一种软水阀活塞组件。
在本申请实施例中,如图15和图16所示,该软水阀活塞组件包括活塞体10、活塞杆20、连接件30及紧固件40,所述活塞体10呈一体设置,所述软水阀活塞组件具有沿所述活塞杆20伸缩方向延伸并呈两端贯通的过水通道,所述连接件30设置在所述活塞杆20上,所述连接件30与所述活塞杆20在所述伸缩方向限位配合,所述紧固件40与所述活塞体10配合以在所述伸缩方向上限位所述连接件30。
需要说明的是,活塞杆可以是除上述实施例中第一阀杆之外的其它杆结构,也可以包括上述实施例中的第一阀杆。
在本实施例中,活塞体10可通过一体注塑成型,用于在伸缩运动过程中实现对软水阀中多路阀的不同水路的切换。举例而言,活塞体10的外周壁开设有沿活塞体10的周向延伸的环形过水槽,在关闭某一水路的位置,活塞体10的外周壁完全堵接于该水路的过水口,从而使水流无法通过;在开启某一水路的位置,过水槽与该水路的过水口连通,从而使水流能通过过水槽流动。
活塞杆20用于带动活塞体10作伸缩运动,具体地,活塞杆20的内端,即位于软水阀内的一端与活塞体10连接,外端与驱动机构连接,通过驱动机构驱动活塞杆20,进而带动活塞体10做伸缩运动,从而实现对多路阀水路的自动切换。连接件30可与活塞杆20固定连接,也可为可拆卸连接,只需满足在伸缩方向限位配合,以使连接件30随活塞杆20一起作伸缩运动。紧固件40与活塞体10配合,紧固件40具有在伸缩方向上与连接件30抵接的限位面,以与活塞体10共同限位连接件30。过水通道可用于与软水阀的排水流道连通,以使软水阀产生的废水能通过过水通道排出,提高了对活塞体10的利用率。
本申请软水阀活塞组件通过使活塞体10一体设置,并使紧固件40与活塞体10配合以限位设置在活塞杆20上的连接件30,由于连接件30与活塞杆20在伸缩方向限位配合,因此紧固件40与连接件30共同构成活塞杆20与活塞体10之间的连接结构,从而活塞杆20能带动活塞体10进行伸缩运动。相比现有技术,本申请软水阀活塞组件零件更少,结构更简单,从而安装更为简便,生产加工成本更低。
进一步地,如图15和图16所示,所述连接件30与所述活塞杆20可拆卸连接,且所述连接件30设于所述活塞杆20的内端。在本实施例中,连接件30可选设于活塞杆20的尾端,以减小活塞杆20的长度,从而减小对空间的占用及对驱动机构动力源的损耗。连接件30与活塞杆20可拆卸连接,便于软水阀活塞组件整体的拆装。
进一步地,如图15和图16所示,所述活塞杆20的外周面开设有过孔21,所述连接件30为长条状并穿置于所述过孔21。在本实施例中,过孔21开设于活塞杆20内端的尾部并贯穿活塞杆20的外周壁,连接件30穿置于过孔21,且连接件30的两端均凸出于活塞杆20的外周壁,由此实现活塞杆20与连接件30的可拆卸连接。
进一步地,如图15和图16所示,所述活塞体10具有沿所述活塞杆20伸缩方向延伸并呈两端贯通的内腔11,所述内腔11的内壁面具有台阶面111,所述紧固件40呈环状设置并嵌设于所述内腔11,所述紧固件40的内环面与所述活塞杆20的外周面之间形成的环形空间与所述内腔11连通,所述连接件30夹置于所述台阶面111与紧固件40之间。
在本实施例中,软水阀活塞组件的过水通道成形于活塞体10的内腔11,活塞体10一端的内壁面沿周向凹设形成沉槽,台阶面111成形于沉槽的侧壁面。紧固件40嵌设于沉槽中,紧固件40环设于活塞杆20的外围,紧固件40的限位面与台阶面111相对,活塞杆20的内端伸入活塞体10的内腔11,使连接件30的两端夹置于台阶面111与紧固件40的限位面之间。可以理解的是,连接件30的长度应小于活塞体10的内腔11的宽度,同时也应满足使沉槽的内壁面能对连接件30沿自身长度方向的运动形成限位。紧固件40的内环面与活塞杆20的外周面之间形成的环形空间与内腔11连通形成过水通道。
当软水阀的驱动组件驱动活塞杆20进行伸入软水阀内的运动时,连接件30随活塞杆20一起运动,推力通过与连接件30抵接的台阶面111从连接件30传递至活塞体10,从而推动活塞体10朝相同方向运动。相反地,当软水阀的驱动组件驱动活塞杆20进行缩出软水阀的运动时,拉力通过紧固件40的限位面传递至紧固件40,而紧固件40又与活塞体10配合,从而拉力通过紧固件40传递至活塞体10,带动活塞体10朝相同方向运动。
进一步地,如图15和图16所示,所述紧固件40与所述活塞体10可拆卸配合。在本实施例中,紧固件40沿伸缩方向具有一定长度,以增加紧固件40与活塞体10的配合面积,使紧固件40与活塞体10的配合更稳固。紧固件40与活塞体10可拆卸配合,便于组装及拆卸更换。具体地,紧固件40的外周面可设置外螺纹,活塞体10的内周面可设置内螺纹,以使紧固件40与活塞体10形成螺纹配合。
进一步地,如图15所示,所述紧固件40背离所述台阶面111的端面上开设有卡接缺口41。在本实施例中,卡接缺口41可选为两个并在紧固件40的周向上相对。在组装或拆卸紧固件40时,通过拆装工具卡接于卡接缺口41,使得对紧固件40的拆装更加方便。
进一步地,如图15所示,所述紧固件40朝向所述台阶面111的一面开设有限位缺口42,所述连接件30卡接于所述限位缺口42。在本实施例中,限位缺口42的数量可选为两个并在紧固件40的周向上相对,连接件30的两端分别卡接于两限位缺口42,以使紧固件40与连接件30之间的限位连接更加稳固。

在本实施例中,水处理设备还包括离子交换罐80及盐箱,离子交换罐80具有交换口81,离子交换罐80的内腔装有离子交换滤料,如软化树脂。在软化产水的过程中,离子交换罐80内的离子交换滤料可将原水中的钙离子、镁离子置换成钠离子以产生软化水;在再生过程中,通过盐箱中的钠离子将离子交换罐80的钙离子及镁离子置换出来以实现循环再利用。离子交换罐80的交换口81通常朝上设置,离子交换滤料位于离子交换罐80的底部。软水阀10的安装头11朝下安装于离子交换罐80的交换口81,以使软水阀10的阀腔与离子交换罐80的内腔连通。软水阀10还包括位于其阀腔内的阀芯组件,用以将自外接管路进入阀腔的水导向离子交换罐80以实现软化产水、吸盐正洗、吸盐反洗等工况,水经离子交换罐80交换离子实现水质软化后,再留回软水阀10的阀腔并进一步流出阀腔供用户使用。
安装头11的内部成形有进水通道121及出水通道131,阀腔内的水从出水通道131流出软水流向离子交换罐80进行离子交换,再从离子交换罐80通过进水通道121流回软水阀10并进一步流出阀腔供用户使用。可以理解的是,进水通道121与出水通道131相互隔绝,以防止原水与软水在进出软水阀10的过程中相互串流。本实施例中,出水通道131环设于进水通道121的外围,中心管20用以连接进水通道121与离子交换罐80,以使软水从离子交换罐80流向进水通道121;同时中心管20还用以隔绝进水通道121与出水通道131,原水从出水通道131流经中心管20的外围进入交换罐,软水经中心管20的管腔流向进水通道121。

在装配过程中心管20与软水阀10的过程中,通过连接座30便可实现简单方便的装配,提高了水处理设备整体的装配效率。此外,若中心管20与安装头11之间的装配出现异常错位的情况,由于中心管20与安装头11之间有连接座30在承受装配错位产生的作用力,因此装配异常的中心管20与软水阀10更易于拆卸,且不会对中心管20与软水阀10造成损坏,即不会使软水阀10直接报废,只需更换连接座30即可,由此降低了软水阀10在装配过程中的损坏风险,从而降低了不良品比例,减少了不良品造成的生产成本。
本申请连接组件通过连接座30来连接软水阀10与中心管20,使得软水阀10不需要二次加工便可与中心管20连接,简化了软水阀10的整体结构;此外,连接组件还使得软水阀10与中心管20的连接更加简单方便,从而提高了水处理设备的装配效率。
进一步地,如图30至图37所示,所述安装头11包括第一环形筒12,所述第一环形筒12围合形成进水通道121;所述连接座30包括第一连接筒31,所述第一连接筒31插接于所述第一环形筒12,所述中心管20插接于所述第一连接筒31,以与所述进水通道121连通。在本实施例中,中心管20通过第一连接筒31与进水通道121连通,从而第一环形筒12不需要加工成形用于与中心管20固定连接的结构便可简单方便地与中心管20固定相接并连通。第一连接筒31的外壁可选与第一环形筒12的内壁密封配合,中心管20的外壁可选与第一环形筒12的内壁密封配合,以使中心管20与进水通道121密封连通,防止软水流失或原水串流至进水通道121。
进一步地,如图31至图36所示,所述第一连接筒31的外周壁成形有外台阶311、内周壁成形有与所述外台阶311对应的内台阶312,所述第一环形筒12抵接于所述外台阶311,所述中心管20抵接于所述内台阶312。在本实施例中,第一连接筒31位于过水通道内的部分与外露于过水通道的部分形成外台阶311及内台阶312,外台阶311的台阶面朝上,第一环形筒12的下端面抵接于外台阶311的台阶面;内台阶312的台阶面朝下,中心管20的上端面抵接于内台阶312的台阶面;由此,分别实现了第一环形筒12与第一连接筒31的定位抵接,及中心管20与第一连接筒31的定位抵接,从而使得第一连接筒31与第一环形筒12及中心管20的安装更加简单方便。
进一步地,如图30至图36所示,所述第一连接筒31位于所述进水通道121内一端的外周壁开设有沿周向延伸的第一密封槽313,所述连接组件还包括设置于所述第一密封槽313的第一密封圈40。在本实施例中,第一密封槽313开设于第一连接筒31的外周壁,第一密封圈40设置于第一密封槽313,从而不需要对第一环形筒12进行加工便可实现第一连接筒31与第一环形筒12的密封配合。在装配连接座30时只需将第一密封圈40套设于第一密封槽313后在插接于第一环形筒12即可,提高了连接组件的密封性能,从而提高了水处理设备整体的密封性能。
进一步地,如图30至图36所示,所述第一连接筒31远离所述第一环形筒12一端的内壁凹设有沿周向延伸的第二密封槽314,所述连接组件还包括设置于所述第二密封槽314的第二密封圈50。在本实施例中,第二密封槽314开设于第一连接筒31的内周壁,第二密封圈50设置于第二密封槽314,从而不需要对中心管20进行加工便可实现第一连接筒31与中心管20的密封配合,从而实现了中心管20与过水通道的密封连通,提高了连接组件的密封性能,从而提高了水处理设备整体的密封性能。
进一步地,如图30至图36所示,所述第一连接筒31包括沿其轴向依次邻接的插接筒32及套接筒33,所述插接筒32插接于所述第一环形筒12,所述套接筒33连接于所述插接筒32的外壁并环设于所述中心管20的外围,所述套接筒33与所述中心管20之间形成环形的安装空间;所述连接组件还包括固定件60,所述固定件60设置于所述安装空间,以固定所述第二密封圈50。
在本实施例中,插接筒32的上端插接于第一环形筒12,套接筒33上端的内壁连接于插接筒32下端的外壁,套接筒33的直径大于插接筒32,中心管20插接于插接筒32,以使套接筒33的内壁与中心管20的外壁之间形成安装空间。
在上述实施例中,在装配中心管20时,会先将第二密封圈50嵌设于第二密封槽314后,再使中心管20穿过第二密封圈50,但受限于第一连接筒31本身的壁厚,第二密封槽314的深度较小,不利于第二密封圈50的稳固安装,中心管20在穿过第二密封圈50时中心管20与第二密封圈50配合产生的摩擦力会导致第二密封圈50从第二密封槽314脱落或错位,从而无法实现稳定密封。因此,本实施例可选使第二密封槽314邻近并贯穿插接筒32的下端敞口,使得第二密封槽314与环形空间相连通,从而使第二密封圈50的下表面朝向安装空间,在通过固定于安装空间的固定件60朝上抵接于第二密封圈50的下表面,以将第二密封圈50压固于第二密封槽314。由此,使得第二密封圈50的安装更加简单、可靠,同时提高了中心管20与插接筒32之间的密封性能,从而提高了水处理设备整体的密封性能。
进一步地,如图33至图36所示,所述固定件60两端贯通并环设于所述安装空间,所述固定件60的外周壁凸设有卡扣61,所述套接筒33开设有与所述卡扣61适配的卡孔331。在本实施例中,固定件60沿安装空间的周向延伸,以增加与第二密封圈50的接触面积,使得第二密封圈50的安装更加稳固。中心管20穿过固定件60及第二密封圈50后插接于插接筒32。卡扣61的限位面朝下并卡接于卡孔331的下边缘,以对第二密封圈50形成朝上的支撑压固力。卡扣61的数量为多个并沿固定件60的周向间隔设置,卡孔331数量及形状与卡扣61相对应,以使固定件60与套接筒33的连接更加稳固。
进一步地,如图30至图36所示,所述安装头11还包括环设于所述第一环形筒12外围的第二环形筒13,所述第一环形筒12与第二环形筒13之间形成出水通道131;所述连接座30包括沿其周向邻接于所述套接筒33的第二连接筒34,所述第二连接筒34的内壁与所述套接筒33的外壁之间形成环形的过水流道35,所述过水流道35与所述出水通道131连通,所述水处理设备还包括环设于所述中心管20外围并与所述出水通道131连通的上布水器70,所述上布水器70插接于所述第二连接筒34。
在本实施例中,第二环形筒13的下端凸出于第一环形筒12,第二连接筒34外露于安装头11,且第二环形筒13的下端壁抵接于第二连接筒34的上端壁,由此使第二连接筒34与第二环形筒13形成定位抵接。过水流道35与出水通道131连通,上布水器70与过水流道35连通,上布水器70用以均衡单位截面积的过水量,以使原水更分散地流进离子交换罐80,以增加原水与离子交换罐80内交换滤料的接触面积,从而提高离子交换的效率,以提高软水的产水效率及产水质量。上布水器70的内壁与中心管20的外壁之间形成布水空间,原水从出水通道131依次经过水流道35及布水空间流入离子交换罐80进行离子交换形成软水,软水再通过中心管20流向进水通道121。
上布水器70插接于第二连接筒34,即上布水器70插接于连接座30,由此,上布水器70不需要直接与第二环形筒13接触安装,即第二环形筒13不需要加工成形用以固定上布水器70的结构,从而简化了软水阀10的整体结构,也使上布水器70与软水阀10之间的安装更加简单方便。此外,若上布水器70与连接座30,或连接座30与安装头11之间的装配出现异常错位的情况,由于上布水器70与安装头11之间有连接座30在承受装配错位产生的作用力,因此装配异常的上布水器70与软水阀10更易于拆卸调整,且不会对上布水器70与软水阀10造成损坏,即不会使软水阀10直接报废,只需更换连接座30即可,由此降低了软水阀10在装配过程中的损坏风险,从而降低了不良品比例,减少了不良品造成的生产成本。
进一步地,如图30至图33所示,所述连接座30的内壁凸设有第一卡凸37,所述第一卡凸37的限位面朝向所述软水阀10,所述上布水器70的外壁凸设有沿周向延伸的第一凸缘71,所述第一凸缘71搭接于所述第一卡凸37的限位面。在本实施例中,第一卡凸37的限位面朝上抵接于第一凸缘71的下表面,第一卡凸37的数量可选为多个并沿周向间隔设置,以使上布水器70与连接座30的安装更加稳固。
进一步地,如图30至图33所示,所述上布水器70的外壁在所述第一凸缘71远离所述软水阀10的一侧还凸设有沿周向延伸的第二凸缘72,所述连接座30的内壁凸设有与所述第二凸缘72适配的第二卡凸38。在本实施例中,第二凸缘72凸设于第一凸缘71的下侧,第二卡凸38凸设于第一卡凸37的下侧,第二卡凸38的限位面朝上抵接于第二凸缘72的下表面,第二卡凸38的数量可选为多个并沿周向间隔设置,以使上布水器70与连接座30的安装更加稳固。
进一步地,如图30所示,所述第一卡凸37的数量为多个并沿周向间隔设置,所述第二卡凸38的数量为多个并沿周向间隔设置,多个所述第一卡凸37及第二卡凸38沿所述连接座30的轴向交错设置。在本实施例中,第一卡凸37及第二卡凸38交错设置,可方便第一凸缘71及第二凸缘72的卡接或拆卸,同时还便于对第一卡凸37及第二卡凸38的加工成型。在实际应用中,第一卡凸37及第二卡凸38分别成形有倾斜朝下的第一导向斜面及第二导向斜面,以方便第一凸缘71及第二凸缘72分别朝上延伸第一导向斜面及第二导向斜面滑动至卡接于第一卡凸37及第二卡凸38的限位面,使得上布水器70的安装更加简单方便。
进一步地,如图30至图33所示,所述连接座30还包括连接所述第二连接筒34内壁与所述套接筒33外壁的连接筋36,所述连接筋36的数量为多个并沿所述过水流道35的周向间隔设置。在本实施例中,连接筋36用以连接套接筒33及第二连接筒34,即用以连接第一连接筒31及第二连接筒34,以及校直并稳定流经过水流道35的水流。当软水阀10在高水压的环境下工作时,由于过水流道35本身的过水面积较小,高压水流流经过水流道35时容易紊乱导致水流不通畅,降低水处理设备产水的稳定性。多个连接筋36沿过水流道35的周向间隔设置,能对流经该处的水流形成有效引导及分流,从而使得流经过水流道35的水流更加有序稳定,提高了水处理设备的整体稳定性。
进一步地,如图31所示,所述连接筋36的宽度自邻近所述第一连接筒31一端朝邻近所述第二连接筒34一端递增。在本实施例中,连接筋36包括连接于第一连接筒31的引流部361、连接于第二连接筒34的导流部363以及连接引流部361与导流部363的分流部362,引流部361用以将流动方向混乱的水引导至沿轴向流动;分流部362用以将流经其的水流分隔,使经引流部361引导后的大股的紊乱水流分隔为小股的稳定水流,以更稳定地流过过水流道35;导流部363的宽度自上朝下递增以形成两相背离的导流斜面,用以使经分流部362分流后的小股水流更快地汇流形成稳定的大股水流流经过水流道35,从而提高流出过水流道35的水流的流速与流量。可以理解的是,引流部361与第一连接筒31及分流部362,导流部363与第二连接筒34及分流部362均通过光滑的曲面过渡连接,以提高对水流的校直稳定效果。
进一步地,如图30所示,所述第二连接筒34邻近所述第一连接筒31一端的内壁凸设有凸筋341,所述连接筋36连接于所述凸筋341。凸筋341凸设于第二连接筒34的上端并沿周向间断延伸,以方便第一卡凸37及第二卡凸38的拔模成型。凸筋341用以加强连接筋36与第二连接通道连接强度,以提高连接座30整体的结构强度。此外,第一凸缘71的上表面抵接于凸筋341的下表面,以将第一凸缘71限位于凸筋341与第一卡凸37之间,进一步限位上布水器70。在实际应用中,第一连接筒31的下端还凸设有加强筋332,连接筋36连接于加强筋332,以加强连接筋36与第一连接筒31的连接强度,提高连接座30整体的结构强度。
进一步地,所述第一连接筒31、第二连接筒34及连接筋36一体设置。在本实施例中,第一连接筒31、第二连接筒34及连接筋36一体设置,以方便对连接座30一体注塑成型,从而减少加工工序,降低生产成本。
