Description

流体混合机构 技术领域
本发明涉及流体混合技术领域，特别是涉及一种流体混合机构。
背景技术
传统的流体混合机构包括混合管。混合管设有两个以上进料通道，进料通道通过入料管连接至储料设备。储料设备中所储存的流体通过进料通道进入到混合管中进行混合。然而，流体混合机构用于制作凝结性的混合胶液或混合浆液过程中，混合胶液或混合浆液若因为混合管的两端压力差而逆流至进料通道及入料管中时，将会在入料管或进料通道中出现凝固堵塞的不良现象。
发明内容
基于此，有必要克服现有技术的缺陷，提供一种流体混合机构，它能够避免混合后的流体出现逆流现象。
其技术方案如下：一种流体混合机构，包括：接头组件，所述接头组件具有两个以上流体通道，所述流体通道的一端用于通入待混合流体；单向阀，所述单向阀为两个以上，所述单向阀与所述流体通道相应设置，所述单向阀设置在所述流体通道中；及混合管，所述混合管与所述流体通道的另一端相连通。
上述的流体混合机构，待混合流体进入到接头组件的流体通道中后，由于流体通道设有单向阀，如此待混合流体只能单向流通至混合管中进行混合，不会出现逆流现象。用于制作凝结性的混合胶液或混合浆液过程中，便能够避免混合胶液或混合浆液逆流至进料通道或入料管中而导致的凝固堵塞的不良现象。
在其中一个实施例中，所述接头组件包括安装块与盖板，所述安装块设有两个以上第一槽体与两个以上第一流体通道，所述第一槽体、所述第一流体通道与所述单向阀相应设置，所述第一流体通道一端与所述第一槽体相连通构成 所述流体通道，所述第一流体通道另一端与所述混合管相连通；所述单向阀装设在所述第一槽体中；所述盖板盖设在所述安装块上，所述盖板设有两个以上进料口，所述进料口与所述第一槽体相应设置，所述进料口与所述第一槽体相连通。如此，待混合流体通过进料口进入到单向阀中，通过单向阀进入到第一流体通道中。
在其中一个实施例中，各个所述第一流体通道的内径比与各个所述待混合流体的体积比相应设置。例如：待混合流体为三种，体积配比为20：5：1，那么第一流体通道相应为三个，且内径比例关系为20：5：1。如此，第一流体通道中各个待混合流体的流速相同的情况下，体积配比满足预设要求，这样便于将两种以上流体较好地混合。
在其中一个实施例中，所述接头组件还包括用于插入至所述混合管的插嘴，所述插嘴与所述安装块远离所述第一槽体的一侧相连，所述插嘴设有两个以上第二流体通道，所述第二流体通道与所述第一流体通道相应设置，所述第二流体通道一端与所述第一流体通道相连通，所述第二流体通道另一端与所述混合管相连通；所述第一流体通道相对于所述混合管的轴心方向倾斜设置，且所述第一流体通道与所述第二流体通道相连的一端比所述第一流体通道另一端更靠近所述混合管的轴心。如此，插嘴能够便于将各个第一流体通道中的待混合流体通过第二流体通道汇聚至混合管中，从而提高待混合流体的混合效果。
在其中一个实施例中，所述盖板设有两个以上第二槽体，所述第二槽体与所述进料口相应设置，所述单向阀一部分装设在所述第一槽体中，所述单向阀另一部分装设在所述第二槽体中。如此，各个进料口进入的待混合物料能够相应进入到各个单向阀中，在安装块中不会发生混合现象。
在其中一个实施例中，所述单向阀包括阀体，所述阀体的其中一端面设有绕所述第一流体通道的进口端设置的第一安装槽，所述第一安装槽中设有第一密封圈；所述阀体的另一端面设有绕所述进料口设置的第二安装槽，所述第二安装槽中设有第二密封圈。如此，能够保证待混合物料从进料口进入到单向阀，并从单向阀流出至第一流体通道中，使安装块具有较好的密封性。
在其中一个实施例中，所述单向阀还包括阀芯、弹簧及第三密封圈，所述阀体设有第三流体通道，所述第三流体通道的侧壁具有绕其周向设置的第一凸缘；所述阀芯装设在所述第三流体通道内、并能够沿着所述第三流体通道移动，所述阀芯的一端外侧壁设置有第二凸缘，所述阀芯的另一端外侧壁具有绕其周向设置的第三安装槽；所述弹簧套设在所述阀芯上、并位于所述第三流体通道内部，所述弹簧位于所述第一凸缘与所述第二凸缘之间；所述第三密封圈可拆卸装设在所述第三安装槽中，所述第三密封圈用于与所述第一凸缘背向所述第二凸缘的侧面抵触配合。正常情况下，弹簧处于压缩状态，在弹簧的弹力作用下，阀芯上的第三密封圈抵触第一凸缘背向所述第二凸缘的侧面，单向阀为不流通状态；当阀体的第三流体通道中装设有弹簧的一端的流体压力大于第三流体通道另一端时，流体将推动阀芯移动，阀芯上的第一密封圈将与第一凸缘分离，此时阀体内的第三流体通道单向流通；若阀体的第三流体通道中装设有弹簧的一端的流体压力小于第三流体通道另一端时，阀芯上的第三密封圈将始终抵触第一凸缘背向所述第二凸缘的侧面，单向阀为不流通状态。由于第三密封圈可拆卸地装设在第三安装槽中，如此当需要对单向阀进行维护操作时，先将第三密封圈拆掉，便能将阀芯从第三流体通道中抽出，阀芯的拆装操作较为方便，便于进行维护，无需整体更换，能够大大降低使用成本。
在其中一个实施例中，所述阀芯远离所述第一凸缘的端面向内延伸形成有第一流体孔，所述阀芯的侧壁上设有第二流体孔，所述第二流体孔与所述第一流体孔相连通，当所述第一密封圈抵触所述第二凸缘的侧面时，所述第二流体孔与所述第三流体通道靠近所述第一密封圈的一端不连通；当所述第一密封圈与所述第二凸缘的侧面相分离时，所述第二流体孔与所述第三流体通道靠近所述第一密封圈的一端相连通。如此，流体通过阀芯的第一流体孔、第二流体孔进入后，当流体压力较大时，能够推动阀芯使阀芯的第一密封圈与第一凸缘分离，经过第二流体孔流出。单向阀对流体的压力感应较为灵敏，可以相应缩短阀体、阀芯的长度，减小单向阀的尺寸。
在其中一个实施例中，所述第二流体孔为两个以上，所述第二流体孔等间 隔设置在所述阀芯的侧壁上。如此，流体从阀芯的多个第二流体孔同步流出，阀芯受力较为均衡，流体的流动效果较好。

具体实施方式
为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图对本发明的具体实施方式做详细的说明。在下面的描述中阐述了很多具体细节以便于充分理解本发明。但是本发明能够以很多不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本发明内涵的情况下做类似改进，因此本发明不受下面公开的具体实施例的限制。
在本发明的描述中，需要理解的是，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。在本发明的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。
在本发明的描述中，需要理解的是，当一个元件被认为是“连接”另一个元件，可以是直接连接到另一个元件或者可能同时存在中间元件。相反，当元件为称作“直接”与另一元件连接时，不存在中间元件。
如图1及图2所示，一种流体混合机构，包括接头组件10、单向阀20及混合管30。所述接头组件10具有两个以上流体通道。所述流体通道的一端用于通入待混合流体。所述单向阀20为两个以上，所述单向阀20与所述流体通道相应设置，所述单向阀20设置在所述流体通道中。所述混合管30与所述流体通道的另一端相连通。
上述的流体混合机构，待混合流体进入到接头组件10的流体通道中后，由于流体通道设有单向阀20，如此待混合流体只能单向流通至混合管30中进行混合，不会出现逆流现象。用于制作凝结性的混合胶液或混合浆液过程中，便能够避免混合胶液或混合浆液逆流至进料通道或入料管中而导致的凝固堵塞的不良现象。
本实施例中，请再参阅图1至图3，所述接头组件10包括安装块11与盖板12。所述安装块11设有两个以上第一槽体111与两个以上第一流体通道112。 所述第一槽体111、所述第一流体通道112与所述单向阀20相应设置。所述第一流体通道112一端与所述第一槽体111相连通构成所述流体通道，所述第一流体通道112另一端与所述混合管30相连通。所述单向阀20装设在所述第一槽体111中。所述盖板12盖设在所述安装块11上，所述盖板12设有两个以上进料口121。所述进料口121与所述第一槽体111相应设置，所述进料口121与所述第一槽体111相连通。如此，待混合流体通过进料口121进入到单向阀20中，通过单向阀20进入到第一流体通道112中。
此外，请参阅图4，各个所述第一流体通道112的内径比与各个所述待混合流体的体积比相应设置。例如：待混合流体为三种，体积配比为20：5：1，那么第一流体通道112相应为三个，且内径比例关系为20：5：1。如此，第一流体通道112中各个待混合流体的流速相同的情况下，体积配比满足预设要求，这样便于将两种以上流体较好地混合。
进一步地，所述接头组件10还包括用于插入至所述混合管30的插嘴13。所述插嘴13与所述安装块11远离所述第一槽体111的一侧相连，所述插嘴13设有两个以上第二流体通道131。所述第二流体通道131与所述第一流体通道112相应设置，所述第二流体通道131一端与所述第一流体通道112相连通，所述第二流体通道131另一端与所述混合管30相连通。所述第一流体通道112相对于所述混合管30的轴心方向倾斜设置，且所述第一流体通道112与所述第二流体通道131相连的一端比所述第一流体通道112另一端更靠近所述混合管30的轴心。如此，插嘴13能够便于将各个第一流体通道112中的待混合流体通过第二流体通道131汇聚至混合管30中，从而提高待混合流体的混合效果。
进一步地，请参阅图5至图7，所述盖板12设有两个以上第二槽体122。所述第二槽体122与所述进料口121相应设置。所述单向阀20一部分装设在所述第一槽体111中，所述单向阀20另一部分装设在所述第二槽体122中。如此，各个进料口121进入的待混合物料能够相应进入到各个单向阀20中，在安装块11中不会发生混合现象。
更进一步地，请参阅图7至图11，所述单向阀20包括阀体21。所述阀体21的其中一端面设有绕所述第一流体通道112的进口端设置的第一安装槽213。所述第一安装槽213中设有第一密封圈24。所述阀体21的另一端面设有绕所述进料口121设置的第二安装槽214。所述第二安装槽214中设有第二密封圈25。如此，能够保证待混合物料从进料口121进入到单向阀20，并从单向阀20流出至第一流体通道112中，使安装块11具有较好的密封性。
此外，所述单向阀20还包括阀芯22、弹簧23及第三密封圈26。所述阀体21设有第三流体通道211。所述第三流体通道211的侧壁具有绕其周向设置的第一凸缘212。所述阀芯22装设在所述第三流体通道211内、并能够沿着所述第三流体通道211移动，所述阀芯22的一端外侧壁设置有第二凸缘221，所述阀芯22的另一端外侧壁具有绕其周向设置的第三安装槽222。所述弹簧23套设在所述阀芯22上、并位于所述第三流体通道211内部，所述弹簧23位于所述第一凸缘212与所述第二凸缘221之间。所述第三密封圈26可拆卸地装设在所述第三安装槽222中，所述第三密封圈26用于与所述第一凸缘212背向所述第二凸缘221的侧面抵触配合。正常情况下，弹簧23处于压缩状态，在弹簧23的弹力作用下，阀芯22上的第三密封圈26抵触第一凸缘212背向所述第二凸缘221的侧面，单向阀20为不流通状态；当阀体21的第三流体通道211中装设有弹簧23的一端的流体压力大于第三流体通道211另一端时，流体将推动阀芯22移动，阀芯22上的第一密封圈24将与第一凸缘212分离(如图11所示)，此时阀体21内的第三流体通道211单向流通；若阀体21的第三流体通道211中装设有弹簧23的一端的流体压力小于第三流体通道211另一端时，阀芯22上的第三密封圈26将始终抵触第一凸缘212背向所述第二凸缘221的侧面，单向阀20为不流通状态。由于第三密封圈26可拆卸地装设在第三安装槽222中，如此当需要对单向阀20进行维护操作时，先将第三密封圈26拆掉，便能将阀芯22从第三流体通道211中抽出，阀芯22的拆装操作较为方便，便于进行维护，无需整体更换，能够大大降低使用成本。
另外，所述阀芯22远离所述第一凸缘212的端面向内延伸形成有第一流 体孔223，所述阀芯22的侧壁上设有第二流体孔224。所述第二流体孔224与所述第一流体孔223相连通，当所述第一密封圈24抵触所述第二凸缘221的侧面时，所述第二流体孔224与所述第三流体通道211靠近所述第一密封圈24的一端不连通；当所述第一密封圈24与所述第二凸缘221的侧面相分离时，所述第二流体孔224与所述第三流体通道211靠近所述第一密封圈24的一端相连通。如此，流体通过阀芯22的第一流体孔223、第二流体孔224进入后，当流体压力较大时，能够推动阀芯22使阀芯22的第一密封圈24与第一凸缘212分离，经过第二流体孔224流出。单向阀20对流体的压力感应较为灵敏，可以相应缩短阀体21、阀芯22的长度，减小单向阀20的尺寸。
进一步地，所述第二流体孔224为两个以上。所述第二流体孔224等间隔设置在所述阀芯22的侧壁上。如此，流体从阀芯22的多个第二流体孔224同步流出，阀芯22受力较为均衡，流体的流动效果较好。
进一步地，所述第一凸缘212背向所述第二凸缘221的侧面为朝向所述第二凸缘221倾斜设置的倾斜面2121。所述第一密封圈24为O型密封圈。所述弹簧23一端与所述第一凸缘212相抵触，所述弹簧23另一端与所述第二凸缘221相抵触。如此，第三密封圈26能够便于与第一凸缘212的侧面相抵触，密封性能较好。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
