Description

一种过水间隙可调的排渣阀芯 技术领域
本实用新型属于恒温阀芯技术领域，涉及一种排渣阀芯，特别涉及一种过水间隙可调的排渣阀芯。
背景技术
目前市面的温控阀芯柱塞大多设计为整体式结构，在水质含有杂质的地区使用，经常会应为水中具有杂质的问题而导致柱塞卡住，使得温控阀芯无法使用，其往往需要在阀体的进水口上设置有滤网以防止杂质堵塞阀芯，但是滤网难以阻挡细小杂质进入，大颗粒的杂质会在滤网上堆积堵塞淋浴器，导致无法出水。
另外，在阀体使用的过程中，流经于现温控混合阀内的水会窜入调节手轮的螺纹处而导致该螺纹处结垢的情况发生，影响人们的操作手感。
发明内容
本实用新型的目的是针对现有技术中存在的上述问题，提供了一种结构设计合理且过水间隙可调的排渣阀芯。
本实用新型的目的可通过下列技术方案来实现：一种过水间隙可调的排渣阀芯，其特征在于，该排渣阀芯自上而下依次包括有调节手柄、调节手柄座、螺柱、压帽、连接杆、连接套、上柱塞、偏置弹簧一、下柱塞、芯棒、偏置弹簧二、回流挡圈和壳体，所述的上柱塞、下柱塞、偏置弹簧一、连接杆和连接套组合形成柱塞组件，所述的柱塞组件位于壳体与调节手柄座之间，所述的柱塞组件上端面与调节手柄座相对应的下端面之间具有一个可调的过水间隙一，柱塞组件下端面与壳体相对应的内腔面A之间具有一个可调的过水间隙二，所述的螺柱与压帽形成一个内腔，通过转动调节手柄使螺柱上下移动使连接杆提拉或按压柱塞组件，按压时，所述的上柱塞贴合下柱塞，过水间隙一扩大，提拉时，所述的下柱塞贴合上柱塞，过水间隙二扩大。
在上述的一种过水间隙可调的排渣阀芯中，所述螺柱的底部呈凹字型，且该螺柱的底面为一封闭面,所述的偏置弹簧一的一端与该螺柱的底面相抵靠，另一端抵靠于柱塞上。
在上述的一种过水间隙可调的排渣阀芯中，所述的壳体上开设有分别供冷、热水流入的冷进水口和热进水口，所述壳体的底部开设有混合出水口。
在上述的一种过水间隙可调的排渣阀芯中，所述的上柱塞内开设有若干个呈圆周方向分布的过水孔一，所述的下柱塞内开设有若干个呈圆周方向分布的过水孔二。
在上述的一种过水间隙可调的排渣阀芯中，所述的偏置弹簧一位于上柱塞与下柱塞之间，使上柱塞与下柱塞之间形成活动区间，所述的连接套由下往上依次贯穿于下柱塞和上柱塞的中部，所述的连接杆下端部伸入连接套内并与连接套螺纹固连，上端部伸入螺柱与压帽之间的内腔中。
在上述的一种过水间隙可调的排渣阀芯中，所述的调节手柄通过卡簧固定连接在调节手柄座上，手柄座和壳体通过螺纹连接固定。
在上述的一种过水间隙可调的排渣阀芯中，所述的调节手柄与调节手柄座之间设有起耐磨作用的耐磨垫片，所述的壳体与上柱塞之间设有起密封作用的密封件一，所述的壳体与下柱塞之间设有起密封作用的密封件二，所述的调节手柄与调节手柄座的连接处安装有密封件三，所述的调节手柄座上安装有密封件四，所述的壳体上安装有密封件五。
与现有技术相比，本过水间隙可调的排渣阀芯具有以下优点：
1、相比传统温控阀芯柱塞大多设计为整体式结构，在水质含有杂质的地区使用，经常会应为水中具有杂质的问题而导致柱塞卡住，使得温控阀芯无法使用，其往往需要在阀体的进水口上设置有滤网以防止杂质堵塞阀芯，但是滤网难以阻挡细小杂质进入，大颗粒的杂质会在滤网上堆积堵塞淋浴器，导致无法出水，而本排渣阀芯通过组合式的柱塞组件调节最大过水间隙，将杂质排出；
2、通过上柱塞的过水孔一、偏置弹簧一以及下柱塞的过水孔二减缓了水流流速，使之与进水口二的进水充分混合；
3、在阀体使用的过程中，避免了流经于温控混合阀内的水会窜入调节手轮的螺纹处而导致该螺纹处结垢的情况发生，极大的提高了人们的操作手感。
