Description

Title of Invention:坐便器陶瓷压力阀芯进水阀
#細或
[1] 本发明涉及卫生间坐便器水箱用的进水阀， 尤其是涉及一种结构改良的坐便器 陶瓷压力阀芯进水阀。
背景技术
[2] 目前， 坐便器使用的进水阀， 主要有活塞式、 背压式、 陶瓷阀芯式等止水方式
[3] 但是， 当前市场上大多数为活塞式和背压式进水阀， 由于活塞式和背压式进水 阀的进水、 止水部分的零件均釆用橡胶等塑料材料制成， 因此普遍存在着容易 老化变形、 使用寿命短、 压力不同吋 （高压、 低压） 进水和止水异常、 慢渗漏 、 进水噪音过大、 水位控制精度低等诸多缺陷， 以上诸多缺陷导致了进水阀在 工作中的各种失效或故障， 从而造成了珍贵水资源的大量浪费。
[4] 近年来， 市场上也出现了陶瓷阀芯式的进水阀， 由于陶瓷阀芯需要动陶瓷阀芯 和定陶瓷阀芯紧密贴紧方能止水，摩擦阻力增加，开启和关闭吋阻力偏大而造成浮 桶偏大。
[5] 也有的陶瓷阀芯式的进水阀， 只利用水对动陶瓷阀芯的压力， 使动陶瓷阀芯和 定陶瓷阀芯产生自吸合， 达到动陶瓷阀芯和定陶瓷阀芯紧密贴紧而止水。 可是 ， 这样仅靠水压来达到动陶瓷阀芯和定陶瓷阀芯的吸合不可靠， 因为各个地区 管路中的自来水水压不同， 而且同一地区管路中的自来水水压也是变化的， 如 果管路中水压较低， 那么动陶瓷阀芯和静陶瓷阀芯之间的压紧力就很小， 不足 以克服阀芯的中心轴以及浮筒等零件由于机械配合和自身重力而产生的摩擦阻 力， 从而就有产生密封不可靠的可能。 另外， 各个地区管路中的水质不尽相同 ， 如果水中混有杂质， 很容易夹杂在动陶瓷阀芯和定陶瓷阀芯之间， 而破坏它 们的紧密贴紧状态， 出现止水异常 （渗漏、 不止水） 和进水阀损坏的结果。
[6] 有鉴于此， 现有的坐便器用进水阀都存在很多不足， 本发明人针对上述缺陷对 现有进水阀结构进行改良， 本案由此产生。 [7] 本发明的目的在于提供一种坐便器陶瓷压力阀芯进水阀， 确实达到进水和止水 功效。
[8] 为了实现上述目的， 本发明的解决方案是：
[9] 坐便器陶瓷压力阀芯进水阀， 包括本体、 中心管、 下套管、 浮筒组件、 抬杆、 陶瓷压力阀芯和防虹吸胶垫； 本体具有进水口、 阀腔和出水口； 中心管的上端 接在本体的进水口上， 下端接至外界水源； 下套管套在中心管外， 且上端接在 本体上， 下套管与中心管之间形成出水通道与本体的出水口相连， 下套管的下 部开有与进水箱相连的阀体出水孔； 陶瓷压力阀芯安装在本体的阀腔中靠近进 水口的位置， 陶瓷压力阀芯包含压力件、 动陶瓷片和静陶瓷片， 动陶瓷片和静 陶瓷片在压力件作用下紧贴在一起， 动陶瓷片上安装有转轴， 转轴的一端从本 体穿出， 通过抬杆与浮筒组件连接， 浮筒组件经由抬杆和转轴带动动陶瓷片转 动， 控制陶瓷压力阀芯的开或关；
[10] 防虹吸胶垫安装在本体的阀腔中靠近出水口的位置； 各构件之间还设有保证水 密性的密封件。
[11] 所述压力件为弹簧， 设置在动陶瓷片和静陶瓷片的一侧， 在弹力作用下， 使动 陶瓷片和静陶瓷片紧贴在一起。
[12] 所述压力件为以同性磁极相对的一对磁铁， 设置在动陶瓷片和静陶瓷片的一侧 ， 在磁铁的斥力作用下， 使动陶瓷片和静陶瓷片紧贴在一起。
[13] 所述静陶瓷片的中心位置开有供转轴穿过的通孔， 通孔周围以中心对称均匀分 布若干梯形出水口； 动陶瓷片在和静陶瓷片紧贴的一侧面中心位置设有供转轴 固定的盲孔， 盲孔周围以中心对称均匀分布若干类似梯形的缺口；
[14] 压力件设置在动陶瓷片的另一侧面； 转轴的里端穿过通孔固定在盲孔上； 通过 转动转轴， 带动动陶瓷片相对静陶瓷片转动， 使缺口与出水口对齐吋进水， 而 缺口与出水口完全错开吋止水。
[15] 所述本体上还具有补水口， 补水口位于防虹吸胶垫安装位置和出水口之间。
[16] 所述本体在阀腔靠近进水口的位置设有一个定位架， 定位架上开有通水孔， 陶 瓷压力阀芯安装在定位架中。 [17] 所述本体的阀腔对应陶瓷压力阀芯的安装位置开有安装口， 在安装口上设有定 位盖和定位螺母， 陶瓷压力阀芯由安装口置入阀腔中。
[18] 所述本体的阀腔对应防虹吸胶垫的安装位置也开有安装口， 在安装口上设有上 盖和带螺纹的顶盖， 防虹吸胶垫由安装口置入阀腔中。
[19] 釆用上述结构后， 本发明工作吋， 水源由中心管的下端进入， 向上流经中心管
、 本体的进水口、 陶瓷压力阀芯， 进入阀腔内， 顶起防虹吸胶垫， 再流经本体 的出水口和出水通道， 最后， 由阀体出水孔流进坐便器水箱内， 实现进水。
[20] 本发明因为釆用陶瓷压力阀芯， 借助压力作用使动陶瓷片和定陶瓷片紧密吸合
， 所以， 不受水压等影响， 皆可确保进水和止水效果。

[35] 如图 1至图 5所示， 是本发明的较佳实施例一。 坐便器陶瓷压力阀芯进水阀， 包 括本体 11、 中心管 28、 下套管 25、 浮筒组件 17、 抬杆 30、 陶瓷压力阀芯 14和防 虹吸胶垫 15。 [36] 本体 11具有进水口 18、 阀腔 19和出水口 20。 此实施例的本体 11上还具有补水口 16, 补水口 16位于防虹吸胶垫 15安装位置和出水口 20之间。 为了便于安装陶瓷 压力阀芯 14和防虹吸胶垫 15， 此实施例本体 11的阀腔 19上对应陶瓷压力阀芯 14 的安装位置开有一个安装口 21， 在安装口 21上设有定位盖 2和定位螺母 1， 本体 1 1的阀腔 19对应防虹吸胶垫 15的安装位置也开有一个安装口 22， 在安装口 22上设 有上盖 13和带螺纹的顶盖 12， 本体 11在阀腔 18靠近进水口 18的位置还设有一个 定位架 10， 定位架 10上开有通水孔。
[37] 中心管 28的上端接在本体 11的进水口 18上， 下端接至外界水源。
[38] 下套管 25套在中心管 28外， 且上端接在本体 11上。 下套管 25与中心管 28之间形 成出水通道 4与本体 11的出水口 20相连通。 下套管 25的下部开有与进水箱相连的 阀体出水孔 3。
[39] 陶瓷压力阀芯 14由安装口 21置入阀腔 19中， 安装在本体 11的阀腔 19中靠近进水 口 18的位置， 并借助定位架 10、 定位盖 2和定位螺母 1安装定位。 陶瓷压力阀芯 1 4包含压力件 （此实施例一为一对磁铁 9) 、 动陶瓷片 8和静陶瓷片 6。 静陶瓷片 6 的具体结构如图 9至图 12所示， 中心位置开有通孔 61， 通孔 61周围以中心对称均 匀分布若干梯形出水口 62。 动陶瓷片 8的具体结构如图 6至图 8所示， 在和静陶瓷 片 6紧贴的一侧面中心位置设有盲孔 81， 盲孔 81周围以中心对称均匀分布若干类 似梯形的缺口 82。 如此结构的动陶瓷片 8和静陶瓷片 6， 使得模具简单， 易于加 工， 而且， 动陶瓷片 8和静陶瓷片 6的相对位置稳定， 进水和止水动作更准确。 一对磁铁 9以同性磁极相对， 设置在动陶瓷片 8的另一侧， 在磁铁 9同性相斥的作 用力下， 使动陶瓷片 8和静陶瓷片 6紧贴在一起。
[40] 转轴 5安装在动陶瓷片 8上， 转轴 5的里端穿过通孔 61固定在盲孔 81上， 转轴 5的 外端从本体 11穿出， 通过抬杆 30与浮筒组件 17连接。 受浮筒组件 17起伏带动， 由抬杆 30和转轴 5传动于动陶瓷片 8转动， 使动陶瓷片 8相对静陶瓷片 6转动， 当 缺口 82与出水口 62对齐吋陶瓷压力阀芯 14开启进水， 而当缺口 82与出水口 62完 全错开吋陶瓷压力阀芯 14关闭止水。
[41] 防虹吸胶垫 15由安装口 22置入阀腔 19中， 安装在本体 11的阀腔 19中靠近出水口 20的位置， 并借助上盖 13和顶盖 12安装定位。 [42] 以上各构件之间还根据需要设有密封件， 保证水密性， 此为常用件， 图中未逐 一标号。
[43] 本发明使用吋， 是借助螺母、 法兰密封圏以及胶垫等固定安装在坐便器水箱内
[44] 工作吋， 配合图 4所示， 箭头所指为水流方向， 水源由中心管 28的下端进入， 向上流经中心管 28至本体 11的进水口 18， 若浮桶组件 17下伏， 由抬杆 30和转轴 5 带动使陶瓷压力阀芯 14开启进水， 水经陶瓷压力阀芯 14进入阀腔 19内， 顶起防 虹吸胶垫 15， 一部分由补水口 16流出进行补水， 另一部分再流经本体 11的出水 口 21和出水通道 4， 最后， 由阀体出水孔 3流进坐便器水箱内， 实现进水。 当水 位达到设定高度吋， 浮桶组件 17上浮， 由抬杆 30和转轴 5带动使陶瓷压力阀芯 14 关闭止水， 坐便器水箱停止进水。
[45] 再如图 13、 图 14所示， 是本发明的较佳实施例二。 此实施例的结构与实施例一 大致相同， 二者的区别仅在于： 此实施例压力件为弹簧 90， 釆用弹簧 90代替一 对同性磁极相对的磁铁 9， 同样达到将动陶瓷片 8和静陶瓷片 6压紧贴合在一起的 作用， 进水阀的功效和工作原理不变， 故不赞述。
