Description

一种气动隔膜阀
技术领域
本发明涉及一种气动阀门，尤其涉及一种气动隔膜阀。
背景技术
隔膜阀的结构形式与一般阀门很不相同，它是依靠柔软的橡胶膜或塑料膜来控制流体运动的。常用的隔膜阀材质分为铸铁隔膜阀，铸钢隔膜阀，不锈钢隔膜阀，塑料隔膜阀。
传统的隔膜阀内部设置有密封加强凸径，这样密封凸径在与阀体接触时其凸径内容易形成狭缝滞留区，造成阀体内部污染，为此我们提出一种无死角隔膜阀来解决以上存在的问题。
发明内容
本发明为了解决以上问题提供了一种结构简单、双向流通、内表面清洁、密封性能好、操作简单、生产成本低、使用寿命长的气动隔膜阀。
本发明的技术方案是：所述的隔膜阀包括指示盖、执行器、阀杆、阀盖、阀芯、隔膜、阀体、螺母和螺钉，所述的执行器设置在隔膜阀顶部，所述的执行器上部设置指示盖，所述的阀盖通过连接件设置在执行器下部，所述的阀芯设置在阀盖内，所述的阀芯呈碗状，所述的隔膜设置在阀芯下部，所述的阀杆竖直设置在阀盖内，所述的阀体设置在阀盖下部，所述的阀体与阀盖之间设置隔膜填充，所述的阀体与阀盖通过螺母和螺钉固定连接。
本发明结构简单、双向流通、内表面清洁、密封性能好、操作简单、生产成本低、使用寿命长。
附图说明
图1是本发明的结构示意图。
图中1是指示盖，2是执行器，3是阀杆，4是阀盖，5是阀芯，6是隔膜，7是阀体，8是螺母，9是螺钉。
具体实施方式
一种气动隔膜阀，所述的隔膜阀包括指示盖1、执行器2、阀杆3、阀盖4、阀芯5、隔膜6、阀体7、螺母8和螺钉9，所述的执行器2设置在隔膜阀顶部，所述的执行器2上部设置指示盖1，所述的阀盖4通过连接件设置在执行器2下部，所述的阀芯5设置在阀盖4内，所述的阀芯5呈碗状，所述的隔膜6设置在阀芯5下部，所述的阀杆3竖直设置在阀盖4内，所述的阀体7设置在阀盖4下部，所述的阀体7与阀盖4之间设置隔膜6填充，所述的阀体7与阀盖4通过螺母8和螺钉9固定连接。
以上实施例仅用以说明本发明创造而并非限制本发明创造所描述的技术方案；因此，尽管本说明书参照上述的各个实施例对本发明创造已进行了详细的说明，但是，本领域的普通技术人员应当理解，仍然可以对本发明创造进行修改或等同替换；而一切不脱离本发明创造的精神和范围的技术方案及其改进，其均应涵盖在本发明创造的权利要求范围中。
