Description

一种阀芯及阀 技术领域
本发明涉及一种阀芯及阀。
背景技术
现有的阀芯，如中国专利公开号为CN106523737A、专利名称为一种快接阀芯的中国发明专利申请，阀体下部侧面设有L型出水口，阀体下部内侧设有两个进水口。由于出水口在侧面而进水口在底部，使得与其配合的壳体在铸造时较为困难，需要有多个砂芯，进而导致模具增加且操作困难，也会导致壳体的重量较大。
发明内容
本发明提供了一种阀芯，其克服了背景技术所存在的不足。本发明解决其技术问题所采用的技术方案之一是：
一种阀芯，它包括阀体、动片、定片和拨杆，所述定片固定装接在阀体内，所述动片活动装接在阀体内，所述拨杆活动装接在阀体且能带动动片同步活动，所述阀体设有两个进水通道且两个进水通道之进口均设在阀体之侧面，所述阀体底部设有出水通道且出水通道之出口设置在阀体底面，所述定片设有两个分别与两个进水通道之进口相连通的第一过水孔以及一个与出水通道相连通的第二过水孔，所述动片设有一调节槽，该调节槽可将两个进水通道与出水通道同时连通或错开或断开连通。
一较佳实施例之中：所述阀体包括第一阀体和与第一阀体相连接的 第二阀体，第一阀体与第二阀体之间形成阀腔，所述进水通道和出水通道均开设有第一阀体且进水通道之进口与出水通道之出口分别设置在第一阀体之侧面和第一阀体之底面，所述定片和动片均位于阀体内，所述拨杆伸入阀腔内且传动连接动片。
一较佳实施例之中：还包括转动座，该转动座与阀腔转动连接，所述拨杆与转动座转动连接且其底端与动片传动连接。
一较佳实施例之中：还包括转动盘，该转动盘位于阀腔内，且其夹置在转动座与动片之间并与动片同步活动。
一较佳实施例之中：所述转动座设有第一轴孔，所述拨杆设有第二轴孔，另设有转轴，该转轴穿过第二轴孔并与第一轴孔相转动配合。
本发明解决其技术问题所采用的技术方案之二是：一种阀，其应用上述任意一项所述的阀芯，该阀包括壳体，所述壳体设有装配腔、与装配腔相连通的两个进水流道和一个出水流道，所述阀芯安装在装配腔内，两个进水流道分别与两个进水通道相连通，该出水流道与出水通道相连通。
本技术方案与背景技术相比，它具有如下优点：
由于两个进水通道的进口设置在阀体的侧面，出水通道的出口设置在阀体的底面，则壳体的设计可以为：装配腔与进水流道、出水流道均呈接通的状态，只要将阀芯装入装配腔内即可实现水路的连通。而装配腔与进水流道、出水流道均相接通，使得壳体在铸造过程中更加简单，只需一个砂芯就可进行铸造，减少模具和人工操作，也能减轻壳体的重 量。

该阀芯的工作原理是：向上拨动拨杆40，可将进水通道11与出水通道12相连通；转动拨杆40，带动转动座50、转动盘60和动片30同步转动，进而改变调节槽31与进水通道11、出水通道12对应的大小以 调节水温及流量。
