Abstract

本实用新型涉及一种球阀,包括阀体、阀盖、阀座、阀芯、阀杆和把手,阀体的两侧设置阀盖与阀座,阀体中并列设置两个相互连通的阀芯,阀杆的一端连接把手,另一端与阀芯相配合,阀杆和阀体间设置填料及填料压盖,阀芯和阀座间由密封圈密封。本实用新型克服了一般球阀密封性能差,易出现泄漏现象的缺陷,具有结构简单紧凑,控制方便迅速,通断性能好的优点。

Description

球阀
本实用新型涉及一种球阀。
公知的球阀都由阀体、阀盖、阀座、阀芯、阀杆和把手等构件组成,阀体的两侧设置阀盖及阀座,阀体中设有单一的阀芯,阀芯通过阀杆与把手连接以控制介质的通断。这种普通的球阀,因其固有的结构,存在关闭不严密,泄漏现象严重的缺陷。
本实用新型的目的是克服现有技术的上述缺陷,从而提供一种结构简单紧凑、防泄漏性能良好的球阀。
本实用新型包括阀体、阀盖、阀座、阀芯、阀杆和把手,阀体的两侧设置阀盖及阀座,阀杆的一端连接把手,另一端与阀体中的阀芯相配合,阀杆和阀体间设置填料及填料压盖,阀芯和阀座间由密封圈密封,阀体中并列设置两个阀芯,两阀芯间相互连通。
以下结合附图及实施例进一步阐明本实用新型的具体内容。
附图是本实用新型的结构示意图。
如图所示,本实用新型包括阀体3、阀盖2、阀座4、阀芯8、阀杆9和把手1,阀体3两侧设置阀盖2及阀座4,阀座4在阀盖2的内侧,阀体3中并列设置两个阀芯8,两阀芯8间相互连通,阀芯8和阀座4间由密封圈5密封,阀杆9的一端通过螺母7连接把手1,另一端与阀体3中的阀芯8相配合,阀杆9和阀体3间设有填料10及填料压盖6。从进口进入的介质分别经过两阀芯8的控制后从出口排出。
本实用新型通过上述具体结构,使介质需经两阀芯的控制后才能顺利排出,因此,密封性能大大增强,具有结构简单紧凑、控制方便迅速、通断性能好的优点。
