Description

流体系统
本申请要求在2022年08月02日提交中国专利局、申请号为202210920286.X的中国专利申请的优先权,该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及流体输送技术领域,例如涉及流体系统。
背景技术
以流动池为反应腔室,需要设计为其服务的流体系统,用于向流动池中运输样本、试剂、水、清洗剂或具有其它功能的流体,同时还可将流动池中使用过的上述流体运输到废液容器废弃,或运输到其它容器中用于回收再利用。
相关技术中,经典的设计是直接冲刷式的流体系统。这种设计只需要在流动池的入口前设置一段公共管道用于所有种类流体的流入。当流动池使用多种不同的流体时,可以利用阀门或阀门的组合,将连通不同流体的管道分别与公共管道连通,然后使用动力模块驱动流体通过阀门和公共管道进入流动池。
这种设计的第一个问题是流体替换带来的浪费。流体在公共管道和流动池中替换所需的流量与流动空间的内体积成正比,只有最终充满于流动池内的流体才是被有效使用的,而之前用于公共管道和流动池替换所消耗的部分流体就浪费了。第二个问题是流动池对流体使用的限制。在流动池使用的过程中,无法对其他管路进行清洁,从而无法为下一种需要流入流动池的流体做好准备,导致流体输送的灵活性较差。
发明内容
本申请提供流体系统,能够减少流体替换造成的浪费,同时提升灵活性。
本申请提供一种流体系统,包括:
流体容器,所述流体容器设置为存储流体;
控制阀组,包括一级阀组和多个二级阀组,多个所述二级阀组均与所述一级阀组以及所述流体容器连通;
流动池,所述流动池与所述一级阀组的出口通过公共管道连通;
第一动力模块,所述第一动力模块与所述流动池的出口连通,所述第一动 力模块的出口与废液容器和所述流体容器中的至少之一连通;
第二动力模块,所述第二动力模块通过旁通管道与所述一级阀组的旁通口连通,所述第二动力模块的出口与所述废液容器和所述流体容器中的至少之一连通;
所述一级阀组被配置为:将所述多个二级阀组中的一个所述二级阀组与所述公共管道连通,将所述二级阀组的其余的部分或者全部与所述旁通管道连通。
