Abstract

本发明涉及蝶阀技术领域，尤其涉及一种双阀板式三偏心蝶阀，包括结构相同的两个蝶阀，两个蝶阀的阀体之间通过箱体连接在一起，在箱体的底部设有泄压阀，两个蝶阀上都安装有电动执行器。本装置结构简单，由电动执行器在远端进行连锁，可同步开启，也可单独开启。在体腔内装有泄放阀，可在单侧开启状态下进行杂质泄放。由一个阀门代替三个阀门的功能，有效降低安装制造成本。

Description

双阀板式三偏心蝶阀
技术领域
本发明涉及蝶阀技术领域，尤其涉及一种双阀板式三偏心蝶阀。
背景技术
目前管路上都安装一个三偏心蝶阀，在管路检修时需要再在管路上增加一个三偏心蝶阀，这样比较耗费时间，工作效率较低。
发明内容
本发明的目的在于克服上述技术的不足，而提供一种双阀板式三偏心蝶阀。
本发明为实现上述目的，采用以下技术方案：
一种双阀板式三偏心蝶阀，其特征在于：包括结构相同的两个蝶阀，两个蝶阀的阀体之间通过箱体连接在一起，在箱体的底部设有泄压阀，两个蝶阀上都安装有电动执行器。
优选地，所述蝶阀包括阀体、下阀轴、阀座、多层次密封圈、阀板压板、阀板、上阀轴；所述下阀轴通过短轴套安装在所述阀体的下部，下阀轴的上部与所述阀板的下部连接，所述多层次密封圈通过所述阀板压板安装在所述阀板上，所述阀座安装在所述阀体上并与所述多层次密封圈配合，所述上阀轴通过填料机构与所述阀体上部连接，所述上阀轴的上部与所述电动执行器连接，所述电动执行器通过支架安装在所述阀体上。
优选地，所述阀体上部设有填料函，所述填料机构置于填料函中，所述填料机构包括填料垫、填料、填料压套以及填料压板，填料压板与所述阀体上部通过螺栓连接，将料垫、填料、填料压套安装在填料函内。
本发明的有益效果是:相对于现有技术，本装置结构简单，由电动执行器在远端进行连锁，可同步开启，也可单独开启。在体腔内装有泄放阀，可在单侧开启状态下进行杂质泄放。由一个阀门代替三个阀门的功能，有效降低安装制造成本。
附图说明
图1为本发明的结构示意图；
图2为两个蝶阀同时开启的结构示意图；
图3为其中一个蝶阀开启另一个蝶阀闭合的结构示意图。
具体实施方式
下面结合附图及较佳实施例详细说明本发明的具体实施方式。如图1-图3所示，一种双阀板式三偏心蝶阀，包括结构相同的两个蝶阀，所述蝶阀包括阀体1、下阀轴2、阀座3、多层次密封圈4、阀板压板5、阀板6、上阀轴7；所述下阀轴通过短轴套安装在所述阀体的下部，下阀轴的上部与所述阀板的下部连接，所述多层次密封圈通过所述阀板压板安装在所述阀板上，所述阀座安装在所述阀体上并与所述多层次密封圈配合，所述上阀轴通过填料机构与所述阀体上部连接，所述上阀轴的上部与所述电动执行器连接，所述电动执行器通过支架8安装在所述阀体上。所述阀体上部设有填料函，所述填料机构置于填料函中，所述填料机构包括填料垫9、填料10、填料压套11以及填料压板12，填料压板与所述阀体上部通过螺栓连接，将料垫、填料、填料压套安装在填料函内。
两个蝶阀的阀体之间通过箱体13连接在一起，在箱体的底部设有泄压阀14，两个蝶阀上都安装有电动执行器15。本装置结构简单，由电动执行器在远端进行连锁，可同步开启，也可单独开启。在体腔内装有泄放阀，可在单侧开启状态下进行杂质泄放。由一个阀门代替三个阀门的功能，有效降低安装制造成本。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
