Abstract

一种哈氏合金蝶阀，包括哈氏合金制的蝶板和阀杆，蝶板置于阀体中动密封配合，阀杆为两段式，下阀杆上部和蝶板的连接处为圆柱形，上阀杆下部和蝶板的连接处为多棱柱形，蝶板的下端相应设有圆孔，上端则设有多棱柱孔。本实用新型可利用下阀杆作为转动的中心轴，蝶板下端套在下阀杆上，上阀杆则可以驱动蝶板开闭，安装连接方便，定位准确，提高了阀门性能。

Description

哈氏合金蝶阀
技术领域：本实用新型涉及一种蝶阀。
背景技术：在化工、制药等许多工业领域经常要用到哈氏合金制的蝶阀，普通的蝶阀中的阀杆都为单根连接在蝶板侧面，安装到阀体中很不方便，而且蝶板的位置安装精度要求高，使用中磨损较大，密封可靠性降低。
发明内容：针对现有技术的不足，本实用新型提供一种蝶板和阀杆连接准确方便的哈氏合金蝶阀。
本实用新型包括哈氏合金制的蝶板和阀杆，蝶板置于阀体中动密封配合，阀杆为两段式，下阀杆上部和蝶板的连接处为圆柱形，上阀杆下部和蝶板的连接处为多棱柱形，蝶板的下端相应设有圆孔，上端则设有多棱柱孔。
本实用新型可利用下阀杆作为转动的中心轴，蝶板下端套在下阀杆上，上阀杆则可以驱动蝶板开闭，安装连接方便，定位准确，提高了阀门性能。
下面结合附图和实施例进一步说明本实用新型。
附图说明：图1是实施例的主结构示意图；
图2是蝶板的主结构示意图；
图3是图2的俯视图。
实施例：如图所示，蝶板2置于阀体1中动密封配合，阀杆为两段式，下阀杆3上部和蝶板2的连接处为圆柱形，上阀杆4下部和蝶板2的连接处为多棱柱形，蝶板2的下端相应设有圆孔5，上端则设有多棱柱孔6。采用这种结构使蝶板2的安装方便，转动灵活。
本实施例的上阀杆4下部为正六棱柱形，蝶板2的多棱柱孔6相应也为正六棱柱形，这样可以提高上阀杆4和蝶板2的连接强度，转动更加可靠迅速。
