Abstract

一种可替换闸阀的球阀,至少有阀体,阀杆,填料盖和手柄。阀体中部置有两边配着密封圈且带有通孔的球体,其上部有凹槽,与阀杆下端的凸头相配合。有通孔的密封座从阀体一端旋入并使球体与其两边的密封圈紧密接触。阀体端面间距及法兰连接尺寸等于相应闸阀的间距和尺寸。该阀可直接替换闸阀,成本低、性能好、维修损失明显减少。

Description

可替换闸阀的球阀
本实用新型在国际专利分类中,属于阀的范围(F16K),特别是可直接替换闸阀的球阀。
在管路中,有着种类繁多的阀门,闸阀是其中的一类。对于相同通径的阀门中,闸阀阀体两端面的间距,明显偏小。由于闸阀制造与装配较为复杂,特别是结构上存在不可克服的渗漏或损坏,因此应用厂家需经常维修。在换阀时,因上述间距原因,不能用其他阀门替换。
本实用新型的目的是提供一种可替换闸阀的球阀。它制造与装配简单,无渗漏,可直接替换闸阀。
实现上述目的的新方案是:
可替换闸阀的球阀至少包括阀体、阀杆、填料盖和装于阀杆上端的手柄,其特征在于制成一体的阀体的中部,置有左右两边配有密封圈并且带有贯通孔的球体,球体的上部制有凹槽,该凹槽与阀杆下端的凸头相配合;从阀体一端内口旋入并且带有贯通孔的密封座与相应侧的密封圈紧密接触,并使球体与其两边密封圈紧密接触;阀体两端面间距及发兰连接尺寸与相应闸阀的尺寸相同。
按照上述新方案制成的球阀,可直接替换相同通径的闸阀。它制造与装配比较简单,无渗漏,因此具有成本低、性能好,用户维修损失明显减少的优点。
附图为本实用新型中一个实施例的示意图。
下面结合附图,描述实施例。
可替换闸阀的球阀,至少包括阀体1、阀杆7、填料盖6和装于阀杆7上端的手柄9,在制成一体的阀体1的中部,置有左右两边配着密封圈2并且带有贯通孔的球体3,球体3的上部制有凹槽,该凹槽与阀杆7下端的凸头相配合;从阀体1一端内口旋入并且带有贯通孔的密封座4与相应侧的密封圈2紧密接触,并使球体3与其两边的密封圈2紧密接触;阀体1的两端面的间距及发兰连接尺寸与相应通径闸阀的间距、尺寸相同。
为了预防微渗现象,在阀杆7与阀体1之间置有填料环5,并有填料压盖6通过螺栓8压紧密封。为了便于旋入,在密封座4的外口内侧,制有装配凹槽。密封座4的外端面与阀体1发兰面基本相平。
本实用新型不仅可替换闸阀,也可以根据要求替换其他类阀门,替换时必须保证发兰间距及连接尺寸相同。
