Description

高温蝶阀用轴承组合件
技术领域
本发明涉及一种高温蝶阀用轴承组合件。
背景技术
高温阀门不是一直处于工艺参数的温度下工作的，偶尔也在常温下工作，例如调试时，有的工艺系统就是要求阀门温度变化的情况下工作，甚至有的工艺流程是冷热交变，这时阀杆与轴承的配合间隙成为阀门失效的主要因素。
发明内容
本发明的目的在于提供一种结构合理，能方便、及时调整，始终保持阀门正常工作的高温蝶阀用轴承组合件。
本发明的技术解决方案是：
一种高温蝶阀用轴承组合件，包括轴承壳、阀杆，其特征是：在轴承壳内设置至少有二瓣组成的分体式轴承，分体式轴承与轴承壳锥面配合，在轴承壳内、分体式轴承下方设置抵压在轴承壳内部台阶上的套筒，在分体式轴承上设置弹簧，弹簧上设置与轴承壳螺纹连接的可调弹簧座；在弹簧座上设置工具孔。
所述弹簧为波形弹簧、碟形弹簧或圆柱形弹簧。
套筒的热膨胀系数大于分体式轴承及轴承壳的热膨胀系数。
分体式轴承为二瓣、三瓣或四瓣形式。
本发明结构合理，分体式轴承在弹簧力的作用下始终与阀杆保持合理间隙，通过调整弹簧座，进而方便调整弹簧力。
附图说明
下面结合附图和实施例对本发明作进一步说明。
图1是本发明一个实施例的结构示意图。
具体实施方式
一种高温蝶阀用轴承组合件，包括轴承壳1、阀杆2，在轴承壳内设置至少有二瓣组成的分体式轴承3，分体式轴承与轴承壳锥面配合，在轴承壳内、分体式轴承下方设置抵压在轴承壳内部台阶上的套筒4，在分体式轴承上设置弹簧5，弹簧上设置与轴承壳螺纹连接的可调弹簧座6；在弹簧座上设置工具孔7，用于插入工具旋转弹簧座。
所述弹簧为波形弹簧、碟形弹簧或圆柱形弹簧。
套筒的热膨胀系数大于分体式轴承及轴承壳的热膨胀系数。
分体式轴承为二瓣、三瓣或四瓣等形式。
