Description

电动密封蝶阀
技术领域
本发明涉及一种阀门，尤其是涉及一种电动密封蝶阀。
背景技术
阀门是管路流体输送系统中控制部件，它是用来改变通路断面和介质流动方向，具有导流、截止、节流、止回、分流或溢流卸压等功能。用于流体控制的阀门，从最简单的截止阀到极为复杂的自控系统中所用的各种阀门，其品种和规格繁多。阀门可用于控制水、蒸汽、油品、气体、泥浆、各种腐蚀性介质、液态金属和放射性流体等各种类型流体地流动，在一些室内或地下传输管道中都采用电动密封蝶阀，然而控制线路一般采用网线，但是网线过长，导致信号衰减增加，且易受干扰，不利于系统控制信号的传输，而且在远距离操控电动密封蝶阀时，也无法确定阀门关闭或者开启，由于地下传输的管道阀门较多，检修起来也十分的不方便。
发明内容
本发明的主要目的在于提供一种电动密封蝶阀，解决远距离控制电动密封蝶阀的通断和检测电动密封蝶阀是否开启或者关闭。
为解决上述技术问题，本发明所采用的技术方案是：一种电动密封蝶阀，包括阀体、行星轮变速箱、步进电机和控制中心，所述阀体侧面设有支架，支架装有行星轮变速箱和步进电机，阀体上方设有驱动箱，驱动箱内部设有蜗轮蜗杆机构，驱动箱一侧通过行星轮变速箱与步进电机连接，阀体内设有蝶板，蝶板内部的转动轴一端与驱动箱连接，另一端与阀体底部的角度传感器连接；
所述控制中心包括PLC控制器和无线收发模块。
优选方案中，所述控制中心中，信息处理中心将数据通过无线收发模块发送到蝶阀上的无线收发模块，无线收发模块将数据发送到PLC控制器，PLC控制器控制步进电机旋转，角度传感器将蝶板的位置反馈到PLC控制器再通过无线收发模块传输到信息处理中心确保阀门打开或关闭。
优选方案中，所述阀体内壁开有密封圆环槽，密封圆环槽内设有密封胶套，所述蝶板外圆周圈设有开有圆环槽，圆环槽内部设有蝶板密封胶层，蝶板密封胶层突出蝶板外圆表面。
优选方案中，所述密封胶套一面与密封圆环槽贴合，密封胶套另一面突出阀体内表面，密封胶套上设有与蝶板密封胶层相匹配的凹槽。
优选方案中，所述密封胶套和蝶板密封胶层的材质为氟橡胶，或者为硅橡胶。
优选方案中，所述行星轮变速箱的传动比为1:3。
优选方案中，所述驱动箱一侧设有手动转盘。
本发明提供一种电动密封蝶阀，在阀体上设有驱动箱，通过涡轮蜗杆驱动对蝶板进行驱动，蜗杆连接行星轮变速箱，可以对蜗杆进行较大的扭矩输出，行星轮变速箱通过联轴器与步进电机连接，步进电机能够准确的将蝶板转动的转动的位置达到90度，能将电动密封蝶阀开启到最大化，控制中心开启步进电机，使其打开蝶板，蝶板下方的角度传感器将蝶板的位置传输到控制中心，在值班室就能看到阀门是否开启或者关闭，在步进电机开启却没有打开蝶板，此时角度传感器没有角度变化，将生成警报发送到值班室进行维修，在体内壁开有密封圆环槽，密封圆环槽内设有密封胶套，通过密封胶套对阀体进行密封，达到最好的密封效果。
