一种直饮水蝶阀
技术领域
本发明属于阀门，具体涉及一种直饮水蝶阀。
背景技术
随着生活水平的提高，人们对饮用水的要求也越来越高，直饮水是大势所趋。通常输水管道所用软密封蝶阀，阀体和蝶板采用球墨铸铁材质，阀体和蝶板表面均喷涂环氧树脂进行防护，但在阀门使用过程中会产生污染物，如阀体密封面生锈，阀体与阀杆以及蝶板与阀杆的连接处会慢慢的锈蚀等等，锈蚀物经过水的冲刷不断的进入管道，影响水质不能直接饮用。
为了避免阀门在使用过程中对水的污染，满足直饮水的要求，发明了一种直饮水蝶阀。
发明内容
本发明提供一种直饮水蝶阀。有效避免了由于阀门在使用过程中产生污染物，影响水质。
本发明是这样实现的：一种直饮水蝶阀，包括阀体，蝶板，加长轴套以及加长轴套与蝶板孔、加长轴套与阀体孔的密封，定位销及定位销处的密封，蝶板压圈及压圈处的密封，螺钉及螺钉处的密封，紧顶螺钉及紧顶螺钉处的密封。
如上所述的一种直饮水蝶阀，阀体铸件内外表面喷涂环氧树脂，密封面喷焊不锈钢，这样就保证阀门在使用过程中阀体及密封面不会锈蚀，不会影响水质。
如上所述的一种直饮水蝶阀，蝶板表面喷涂环氧树脂，设计成上、下阀杆从两端装入，端部为盲孔结构，阻止水从端部进入。
如上所述的一种直饮水蝶阀，采用加长轴套，轴套直接延伸到蝶板内；在轴套进入蝶板孔口附近设有O型圈；在轴套与阀体孔口附近设有O型圈，实现O型圈与蝶板的环氧层形成密封、O型圈与阀体的环氧层形成密封，阻止水进入，从而防止蝶板与阀体孔内部锈蚀。
如上所述的一种直饮水蝶阀，定位销选用不锈钢材质，在定位销孔口处倒角，设置O型圈，实现O型圈与蝶板定位销孔口处环氧层形成密封，防止水进入，保护螺纹，防止螺纹生锈腐蚀。
如上所述的一种直饮水蝶阀，在压圈采用不锈钢材质，在压圈和蝶板配合的凸台处设有O型圈，使之形成密封；螺钉选用不锈钢材质，螺钉头部下平面设有橡胶垫片，形成密封，防止水的进入，从而防止蝶板上的螺纹孔生锈腐蚀。
如上所述的一种直饮水蝶阀，紧顶螺钉选用不锈钢材质，螺纹上缠绕生胶带，防止水的进入。
本发明的显著效果是：本发明提供了一种直饮水蝶阀，避免了阀门本身在使用过程中产生污染物，对水质产生污染，保证了满足直饮水要求。
