Description

隔膜阀 技术领域
本发明涉及一种流体用阀， 尤指一种可被运用于各种结构的流体用阀的 结构创新， 本发明主要是于本体的结合环围一体成型包覆有一个或一个以上 的金属环； 再于上盖或接头的结合环围一体成型包覆一个或一个以上的金属 环， 如此， 当本体与上盖或接头结合后， 得以让流体用阀得承受更大流体压 力， 提高流体用阀的使用寿命， 并可以被广泛运用于各式的使用场所。 背景技术
按市售的流体用阔， 如图 1所示， 是以膈膜岡解释习知结构， 其包含： 本体 1， 于本体 1的内部设一体成型的流体流通孔 10， 及位于流体流通孔 10的 中央并设置有凸缘 1 1 , 利用该凸缘 11与阀片搭配运作以启闭阀门， 决定流体 流通与否。 又位于本体 1的两侧并设 ί接部 12， 于#接部 12设环围 120， 利用 该环围 120与衔接的管件结合。 再位于本体 1的中央并设上盖 2的结合环围 14 , 该结合环围 14的内侧设孔 140。
上盖 2 , 于上盖 2下方设阀片 20， 前述阀片 20的中央与阀杆 21连设， 且阀 片 20设环围 200， 如此得利用固设组件 22将上盖 2的结合环围 23、 阔片 20的环 围 200及前述本体 1的结合环围 14结合为一体，且为让膈膜阀得承受较大压力， 乃于上盖 2的结合环围 23上方设有孤形金属片 24，弧形金属片 24具有适当的穿 孔 240得以为前述固设组件 22穿过而栓固，再由操作阀杆 21以启闭阀片 20 , 即 可令阀片 20与前述流体流通孔 10的凸缘 11搭配运作， 决定流体流通与否。
惟各式习知流体用阀或阀的结构共同缺点为： 前述习知流体用阀上盖 2 所设的金属片 24为弧形状， 且须由多片组成， 金属片 24并无法与上盖结合成 一体结构， 如前述， 流体压力会攻击膈膜阀较脆弱的位置， 而阀片 20与本体 1 的结合位置就是被攻击之处，使得习知膈膜阀因为无法承受流体压力而破损， 让流体外泄， 且前述金属片 24暴露于外侧， 如果本流体用阀被运用于酸、 碱 性流体或环境时， 金属片 24易受酸、 碱性流体攻击快速锈蚀， 降低膈膜阀的 使用寿命与限制可运用的场所。
为此， 本发明者， 积数十年相关流体用阀的设计、 研发与制造经验， 特 针对前揭习知者的缺点， 加以研究而发明本案。 发明的公开
