Description

一种既大量注出又微量注出色浆的控制阀 技术领域
本发明涉及涂料调色技术领域，具体涉及一种既大量注出又微量注出色浆的控制阀。
背景技术
在调色技术领域，利用往复式泵注出定量色浆是一项关键技术，目前常见的往复式容积泵有活塞泵、柱塞泵、折叠泵等。以活塞泵为例，其一般组成为：缸体，活塞杆、活塞、出浆口。调色对色浆的量有严格的要求，要求泵在注出大量色浆(如大于15毫升)时色浆注出量的误差不能超过一定的百分比(如小于1％)，对于在注出微量色浆(如小于0.5毫升)时色浆注出量的误差同样不能超过一定的百分比(如小于12％)；为了达到这个目的，可以使用两台调色机一台是大泵组成的调色机主要负责注出大量色浆，另一台是小泵组成的调色机负责注出微量色浆；或在同一个泵中一个大截面缸体的大泵并联用一个小截面缸体的小泵，并排设置一对注出大量和注出微量两个泵出系统，上述两种方法都存在所占空间较大，结构复杂，成本高的问题，因此，可以采用在活塞杆下方固定连接一个小活塞杆，同时在缸体内设置一个与小往复杆配合的小缸体，小缸体上设小出浆口，通过大活塞杆和小活塞杆的往复运动实现大量注出或微量注出色浆的目的(以活塞泵为例而不限于活塞泵)。然而对一般色浆注出泵适用的三通换向阀，应用到这种既大量注出又能微量注出色浆的泵不能满足使用要求；专利CN201310045508.9公开的换向阀虽然可以有效解决出浆口处色浆干结现象以及出浆管路内色浆沉积的问题，提高注出色浆精度，然而同样不能满足这种既大量注出又能微量注出色浆的泵的使用要求。

所述色浆桶进出口分支为两个位于阀芯侧方的色浆桶进出口I和色浆桶进出口III后，又分支为两个位于阀芯侧方的色浆桶进出口III和色浆桶进出口Ⅳ，色浆桶进出口III和色浆桶进出口Ⅳ与径向通道II、径向通道III对应；①当径向通道I与色浆桶通道进出口II连通时，径向通道III连通色浆桶分支进出口III，径向通道II连通色浆桶分支进出口Ⅳ，小泵进出口连通色浆桶抽吸色浆；②当径向通道I与色浆桶通道进出口I连通时，径向通道III连通色浆桶分支进出口Ⅳ，径向通道II连通色浆桶分支进出口III，大泵进出口与小泵进出口连通色浆桶抽吸色浆。

如图2a、图2b是容积变化的空间I为折叠泵的折叠体1a的示意图，其中折叠体1a为大泵体，图2a为小往复杆3即小往复件未进入小泵体(即小缸体4)时的大泵工作状态，图2b为小往复杆3进入小缸体4时的小泵工作状态；其工作原理同图1a、图1b一样，折叠体1a等同大泵体1、大往复杆2及与其连接的大往复板2c构成大往复件。其它零件为小往复件3、小泵体4、大泵进出口5、小泵进出口6、导向柱2d，此实施方式也是小泵体4与折叠体1a不同轴的实施方式。
如图2c所示，所述大往复式容积泵为大折叠泵，大往复杆2及与其连接的大往复板2c构成大往复件，大往复杆2推动大往复板2c沿导向柱2d往复运动，大折叠泵体1a底座上设大泵进出口5，大折叠泵体1a(即大泵体)内套设小折叠泵体4a，小折叠泵体4a底座上设小泵进出口6，所述小往复件为大往复板2c对应小折叠泵体4a的部分板面。
如图3、图4所示，为带有本发明控制阀的既大量注出又微量注出色浆的色浆泵的整体结构示意图，为活塞泵，包括大缸体1(即大泵体)、大往复式杆2为活塞杆，活塞杆通过活塞2b实现抽吸或压出，大往复式杆2与活塞2b构成大往复件，活塞2b向缸内伸出小往复杆3，大缸体1和大往复件构成的往复式泵称为大泵，大缸体1底座内设另一个缸体，称为小缸体4(即小泵体)，可直接在大缸体1上挖孔或设管作为小缸体4，大缸体1和小缸体4同轴设置，如图3所示；大往复杆2伸入缸体的一端连接另一个往复杆，称为小往复杆3(即小往复件)，小缸体4可与小往复杆3配合，构成小泵；小缸体4设小泵进出口6，大缸体1设大泵进出口5。小往复杆3伸入小缸体4的长度大于等于大往复杆2行程，此时小往复杆3一直在小缸体4内；小往复杆3伸入小缸体4的长度也可小于大往复杆2行程，如图4所示，此时小往复杆3可脱离小缸体4。大泵进出口5和小泵进出口6配置控制阀，控制阀控制大泵进出口5和小泵进出口6连通色浆桶或者注出。图3、图4为小缸体4与大缸体1同轴设置的实施方式，这样更容易制作和实现。
一种既大量注出又微量注出色浆的控制阀，包括阀体和阀体内设置的阀芯，阀体上设置大泵进出口5、小泵进出口6、色浆桶进出口8和色浆注出口9；在阀芯上设通道，通过旋转阀芯，使得大泵进出口、小泵进出口连通色浆桶或者注出，至少包括下述三个连通结构：
①、大泵进出口连通色浆桶、小泵进出口连通色浆桶、大泵进出口和小泵进出口均连通 色浆桶，前述三种方式单独或者组合；
②、大泵进出口单独注出或者大泵进出口和小泵进出口共同注出，或者大泵进出口连通色浆注出口注出或者大泵进出口和小泵进出口共同连通色浆注出口注出；

如图7a所示为转动阀内的色浆通道图，当径向通道II7c对准色浆注出口9时，圆弧槽7a与色浆桶进出口I8a连通，即大泵进出口色浆通过圆弧槽7a、色浆桶进出口I8a、第一分支通道8y回流至色浆桶，小泵进出口6连通轴心通道7e，轴心通道7e连通径向通道II7c，由径向通道II7c通过色浆注出口9注出微量色浆，其它通道关闭。
如图7b所示，当径向通道III7d对准色浆注出口9时，径向通道I7b与大泵进出口5连通，即大泵进出口5与小泵进出口6同时通过轴心通道7e与径向通道III7d连通，径向通道III7d注出大量色浆，其它通道关闭。
如图7c所示，当径向通道I7b与色浆桶分支进出口II8b连通时，小泵进出口6通过轴心通道7e、径向通道I7b、色浆桶分支进出口II8b连通色浆桶抽吸色浆。
如图7d所示，当径向通道I7b与色浆桶分支进出口I8a连通时，大泵进出口5通过圆弧槽通道7a、色浆桶分支进出口II8b、第二分支通道8x连通色浆桶进出口8，小泵进出口6通过轴心通道7e、径向通道I7b、色浆桶分支进出口I8a、第一分支通道8y同时连通色浆桶进出口8抽吸色浆，以上是假设没有色浆桶分支进出口III8c和色浆桶分支进出口IV8d。
如图6a、6b所示，色浆桶进出口8分支为两个位于阀芯侧方的色浆桶进出口I8a和色浆桶进出口III8b后，又分支为两个位于阀芯侧方的色浆桶分支进出口III8c和色浆桶分支进出口Ⅳ8d，色浆桶分支进出口III8c和色浆桶分支进出口Ⅳ8d与径向通道II7c、径向通道III7d一一对应；①如图7c所示，当径向通道I7b与色浆桶通道进出口II8b连通时，径向通道III7d连通色浆桶分支进出口III8c，径向通道II7c连通色浆桶分支进出口Ⅳ8d，小泵进出口6连通色浆桶抽吸色浆；②如图7d所示，当径向通道I7b与色浆桶通道进出口I8a连通 时，径向通道III7d连通色浆桶分支进出口Ⅳ8d，径向通道II7c连通色浆桶分支进出口III8c，大泵进出口5与小泵进出口6连通色浆桶抽吸色浆。
如图8a、8b、9a、9b所示，为控制阀的另一种结构示意图，控制阀包括阀体II和阀芯II，阀体II上设大泵进出口5和小泵进出口6、色浆桶进出口8和色浆注出口9，其中，色浆桶进出口8通过第一分支通道8y连通色浆桶分支进出口I8a，色浆桶进出口8通过第二分支通道8x连通色浆桶分支进出口II8b，色浆桶进出口8设第三分支通道8z；阀芯II设轴心通道7f、径向通道I7b、径向通道II7c、径向通道III7d分别与轴心通道7f连通，阀芯II表面设圆弧槽通道7a，圆弧槽通道7a、径向通道I7b与大泵进出口5对应，轴心通道7f与小泵进出口6对应部位轴向间隔90°设径向小泵通道I7i、径向小泵通道II7j、径向小泵通道III7k和轴向小泵通道7h：
①图10a当径向通道I7b与色浆桶分支进出口II8b连通时，大泵进出口5与圆弧槽通道7a并与色浆桶通道分支进出口I8a连通，通过第一分支通道8y连通色浆桶进出口8；小泵进出口6通过轴向小泵通道7h、第三分支通道8z与色浆桶进出口8连通，抽吸色浆，其它通道关闭；
②图10b当径向通道III7d对准色浆注出口9时，大泵进出口5通过径向通道I7b与轴心通道7f连通；小泵进出口6通过径向小泵通道III7k与轴心通道7f连通；即大泵进出口5与小泵进出口6同时通过轴心通道7f与径向通道III7d连通，径向通道III7d注出大量色浆，其它通道关闭；
③图10c当径向通道II7c对准色浆注出口9时，圆弧槽7a与色浆桶进出口II8b连通，即大泵进出口5色浆通过第二分支通道8x回流；小泵进出口6通过径向小泵通道I7i连通轴心通道7f，轴心通道7f连通径向通道II7c，由径向通道II7c注出微量色浆，色浆穿过色浆注出口9注出，其它通道关闭。以上是假设没有色浆桶分支进出口III8c和色浆桶分支进出口IV8d。
如图8a、8b，色浆桶进出口8分支为两个位于阀芯侧方的色浆桶进出口I8a和色浆桶进出口II8b后，又分支为两个位于阀芯侧方的色浆桶进出口III8c和色浆桶进出口Ⅳ8d，色浆桶进出口III8c和色浆桶进出口Ⅳ8d与径向通道II7c、径向通道III7d对应；①如图10a所示，当径向通道I7b与色浆桶通道进出口II8b连通时，径向通道III7d连通色浆桶分支进出口III8c，径向通道II7c连通色浆桶分支进出口Ⅳ8d，抽吸色浆；
②如图10d所示，当径向通道I7b与色浆桶通道分支进出口I8a连通时，径向通道II7c与色浆桶分支进出口III8c连通，径向通道III7d与色浆桶进出口Ⅳ8d连通，小泵进出口6与色浆桶连通，大泵进出口封闭，除了抽吸少量色浆外，可以通过抽放色浆清洗径向通道II7c和径向通道III7d出口处的色浆。
图11是本发明控制阀整体结构示意图。如图11、13a、13b所示，大缸体1底座102上设注出口9和色浆桶通道8，底座102轴芯设转轴103，大缸体1内设旋转阀芯IV 101；如图12a、12b所示，旋转阀芯IV101轴芯设小缸体4，小缸体4沿径向伸出小泵进出口6，小缸体4外侧设大泵进出口5，小缸体4沿径向伸出另一个进出口，该进出口与另一个大泵进出口连通构成合并进出口56，这样转动阀芯101，①如图14a，合并进出口56与色浆桶通道8对准，抽吸色浆，色浆100流入缸体内；②如图14b，小泵进出口6对准注出口9，注出微量色浆，大泵进出口5与色浆桶进出口8连通，大泵进出口5回流至色浆桶；③如图14c，大泵进出口5对准注出口9或者合并进出口56对准注出口9，打出大量色浆。
本发明的大往复件的驱动包含手动驱动、步进电机驱动、伺服电机驱动。本发明中控制阀位置的转换包含手工或步进电机或同步电机或带有转位控制的减速电机实现的转换。改变控制阀的方向位置，可实现吸入色浆，微量注出色浆、大量注出色浆、排除空气、清洗泵体的目的，并保证了色浆注出精度和效率。
本发明提供的控制阀不限于以上所述的柱塞泵、活塞泵或折叠泵，也可用于任何具有两个注出系统的泵体，如专利WO2014139135A公开的并排布置的双量筒泵。
