Abstract

一种平板薄片式流量控制器，包括一个底座，一平板薄片式弹性调节片设置于底座内，当流体压力达到设定压力值后此弹性调节片的底面与底座之间限定一在流过的流体压力下改变的控制间隙，其特征在于：所述底座中间有一凸起圆台，此圆台中间设置一出水孔，圆台上有一定位面，圆台周边均匀开设控制间隙，当流体压力小于设定值时平板薄片式弹性调节片底面和定位面分离此时控制间隙不受改变；当流体压力大于设定值后平板薄片式弹性调节片底面受压力作用变形到达定位面，随着压力的上升平板薄片式弹性调节片进一步变形控制间隙变小。此平板薄片式流量控制器可以通过改变平板薄片式弹性调节片的硬度、厚度和控制间隙的宽度等变量来控制流量，使得流量在低压时可以很快的达到设定的上限值，并且随着压力的上升，流量可以很好的保持此上限值。

Description

迷宫式弹性体流量控制器 技术领域
本发明涉及一种流量控制器，特别涉及一种采用弹性材质制备且旁通通道采用迷宫式设置的流量控制器。
背景技术
发明人在较早的专利：2013100268398中揭露了一种迷宫式节流器，上述已经揭露的迷宫式节流器中采用迷宫作为旁通通道来控制通过此通道的流体流量，来获得较佳的流量曲线和更小的噪音，发明人已经注意到，采用此方法进行流量控制，随着管道压力的上升，控制间隙无法实现更好的缩小，导致流量曲线随着压力上升仍然有一定的增加。
发明内容
借助本发明的迷宫式弹性体流量控制器，可以解决上述缺点，从而实现即将描述的其它优点。本发明的迷宫式弹性体流量控制器，采用弹性体材质一体成型，包括一个弹性调节环，该弹性调节环与壳体壁之间限定一在流过的流体压力下改变的控制间隙，从而实现对流量的控制。
本发明的目的通过如下技术方案达到：
一种迷宫式弹性体流量控制器，采用弹性体材质一体成型，包括一个弹性调节环，该弹性调节环与壳体壁之间限定一在流过的流体压力下改变的控制间隙，其特征在于：所述迷宫式弹性体流量控制器配置有至少一个或一对进水口，所述迷宫式弹性体流量控制器还配置有至少一个或一对出水口，在所述进水口和出水口之间配置有至少一个或一对迷宫式旁通通道。
所述迷宫式弹性体流量控制器中间为后端封闭的空腔，所述弹性调节环设置在空腔末端。
所述弹性调节环为薄壁结构。
所述设置成薄壁结构的弹性调节环可以随着管道压力的上升克服恢复力膨胀变形。
所述迷宫式旁通通道由若干对横向设置的密封筋及设置于密封筋之间的凸起齿组成。
所述凸起齿之间组成的通道间隙相同。
所述凸起齿可以为三角形、梯形、长方形或类三角形等形状。
所述控制间隙由弹性调节环和壳体壁所限定。
本发明对比已有技术有以下显著优点：
1.采用弹性体材质一体成型，成本低，生产效率高；
2.弹性调节环与壳体壁之间限定一在流过的流体压力下改变的控制间隙，调节环随着管道压力的上升膨胀越大，这是控制间隙就越小，流量稳定；
3.旁通通道为迷宫式设计，加长其通道距离，降低压力。

具体实施方式
现结合附图和具体实施方式对本发明进一步说明。
本发明的基本思路是弹性调节环与壳体壁之间限定一在流过的流体压力下改变的控制间隙，从而实现对流量的控制。
参考图1、2、3、4、5、6所示，不同实施例的迷宫式弹性体流量控制器1，其可安装于在这里未示出的卫生设备的预设的前端位置中，流经于此未示出的卫生设备的管道中的流体先通过所述迷宫式弹性体流量控制器1后在流入此卫生设备的其他部件。
迷宫式弹性体流量控制器1为此用于即使在越来越大的流入流体的压力时也可以将每单位时间内流过的流量控制在一规定的最大值，迷宫式弹性体流量控制器1为此采用弹性体材质一体成型，其包括一个弹性调节环2，该弹性调节环2与壳体壁3之间限定一在流过的流体压力下改变的控制间隙4，图3、5所示迷宫式弹性体流量控制器1中间为末端封闭的空腔10，设置于其末端的调节环2在流入的流体压力下一直变形到成型轮廓，而同时使得控制间隙4变窄。
为迷宫式弹性体流量控制器配置有至少一个或一对进水口5，所述迷宫式 弹性体流量控制器1还配置有至少一个或一对出水口6，在所述进水口和出水口之间配置有至少一个或一对迷宫式旁通通道7，所述旁通通道7由若干对横向设置的密封筋8及设置于密封筋之间的凸起齿9组成，采用迷宫式设计的旁通通道7尽量延长了流经流体的流道距离。
图6所示另一实施例中，当安装此迷宫式弹性体流量控制器1的卫生设备前端或管道中未设置有过滤系统时，此迷宫式弹性体流量控制器1前端可以设置一过滤筛11进行过滤。
本发明的迷宫式弹性体流量控制器的工作方式是：此迷宫式弹性体流量控制器1安装于卫生设备预设的前端位置中通过侧壁密封，当有流体流经此设备是，流体先流入空腔10中，此时弹性调节片2受到流体压力实现变形，控制间隙4产生变化，同时流体通过进水口5后流入迷宫式旁通通道7，再从出水口6流出进入旁通通道7最后流入卫生设备的其他部件。
因此，本发明的迷宫式弹性体流量控制器不仅能够很好的确保即使在越来越大的流入流体的压力时也可以将每单位时间内流过的流量控制在一规定的最大值，并且采用弹性体材质一体成型，可以很好的实现噪音的控制。
尽管结合优选实施方案具体展示和介绍了本发明，但所属领域的技术人员应该明白，在不脱离所附权利要求书所限定的本发明的精神和范围内，在形式上和细节上可以对本发明做出各种变化，均为本发明的保护范围。
