Description

一种耐腐蝶阀
技术领域
本发明属于阀门领域，尤其是涉及一种耐腐蝶阀。
背景技术
目前，工业用阀门类型多样，被广泛用于化工、食品、水、电等行业，主要起到流体介质的流量调节与截止作用。由于使用场合的不同，其内流经的介质多种多样，如果要在腐蚀性介质中使用，蝶阀的使用寿命将受到影响，现有的蝶阀设计结构同时存在密封效果不好的问题，从而影响蝶阀的使用。
发明内容
本发明要解决的问题是提供一种结构简单、密封效果好的耐腐蝶阀，尤其适合在传输腐蚀性介质的管道中使用。
为解决上述技术问题，本发明采用的技术方案是：一种耐腐蝶阀，包括手柄、传动轴、阀体、蝶板和过滤网，所述阀体内壁为凹凸形，在所述阀体内壁凹凸形处设有密封圈，所述阀体内设有所述蝶板，所述蝶板上垂直设有过滤网，所述手柄与所述传动轴相连，所述传动轴穿过所述阀体，所述蝶板通过所述传动轴与所述手柄连接，所述蝶板的表层上设有耐腐蚀层。
进一步的，所述传动轴与所述蝶板铸为一体。
进一步的，所述密封圈为硫化橡胶密封圈。
进一步的，所述耐腐蚀层为聚氨酯弹性体。
进一步的，所述蝶板和所述过滤网垂直设置，且所述蝶板与过滤网呈90度。
本发明具有的优点和积极效果是：由于采用上述技术方案，蝶板上的过滤网可以挡住过滤介质中的固体杂质，蝶板的表层和过滤网均为耐腐蚀材料，可以在传输腐蚀性介质的管道中使用，传动轴与蝶板铸为一体，防止传动轴与蝶板出现松动或者断裂，增强蝶阀的使用寿命；具有结构简单、功能多样、蝶阀使用寿命长等优点。

具体实施方式
如图1所示，本发明一种耐腐蝶阀，包括手柄1、传动轴2、阀体3、蝶板4和过滤网5，所述阀体3内壁为凹凸形，在所述阀体3内壁凹凸形处设有密封圈6，所述阀体3内设有所述蝶板4，所述蝶板4上垂直设有过滤网5，且所述蝶板4与过滤网5呈90度，所述手柄1与所述传动轴2相连，所述传动轴2穿过所述阀体3，所述蝶板4通过所述传动轴2与所述手柄1连接，所述蝶板4的表层上设有耐腐蚀层，所述传动轴2与所述蝶板4铸为一体，所述密封圈6为硫化橡胶密封圈，所述耐腐蚀层为聚氨酯弹性体。
本实例的工作过程：当需要打开或者关闭阀门时，用力握住并转动手柄1，手柄1通过传动轴2带动所述蝶板转动，根据需要，来转动手柄1的度数，当达到度数要求后，松开手柄1，蝶板4会固定在阀体3内，蝶板4上的过滤网5可以挡住过滤介质中的固体杂质，蝶板4的表层和过滤网5均为耐腐蚀材料，可以在传输腐蚀性介质的管道中使用，传动轴2与蝶板4铸为一体，防止传动轴2与蝶板4出现松动或者断裂，增强蝶阀的使用寿命。
以上对本发明的一个实施例进行了详细说明，但所述内容仅为本发明的较佳实施例，不能被认为用于限定本发明的实施范围。凡依本发明申请范围所作的均等变化与改进等，均应仍归属于本发明的专利涵盖范围之内。
