Description

一种上装式球阀
技术领域
本实用新型涉及一种球阀，特别是涉及一种上装式球阀。 
背景技术
目前使用在冶金、市政、核电行业的上装式球阀，采用整体上装式结构，阀盖安装于阀体之上。检修时拆下阀盖即可更换密封圈，有效防止了带放射性废液对维修人员的伤害和对环境造成的污染。目前通常使用的上装式球阀一般采用斜楔式球体，球体上端面与阀轴的台阶处装有弹簧，虽具有密封可靠、启闭灵活、维修快捷方便等特点，但只适宜安装在水平管道上使用，不能使用于垂直管道。 
发明内容
为了克服现有上装式球阀只适宜安装在水平管道，不能使用于垂直管道的不足，本实用新型提供一种上装式球阀。 
本实用新型解决其技术问题所采用的技术方案是一种上装式球阀，包括阀体、阀盖、阀座、密封圈、球体，阀盖安装在阀体之上，密封圈装在阀座内，球体装在阀体内，阀体内还装有中间体，中间体左端开口，中间体内依次装有阀座、密封圈、球体，中间体开口端内孔上有螺纹，压环旋入中间体内，压紧阀座，中间体与阀体、压环与阀体、阀座之间通过O形圈密封。 
本实用新型的有益效果是可任意位置安装，密封可靠、启闭灵活、维修快捷方便。 
附图说明
下面结合附图和实施例对本实用新型进一步说明。 
图1是实施例的构造图。 
图中：1.阀体；2.压环；3.阀盖；4.间体；5.阀座；6.密封圈；7.球体；8.O形圈。 
具体实施方式
如图1所示，一种上装式球阀，包括阀体1、阀盖3、阀座5、密封圈6、球体7，阀盖3安装在阀体1之上，密封圈6装在阀座5内，球体7装在阀体1内，阀体1内还装有中间体4，中间体4左端开口，中间体4内依次装有阀座5、密封圈6、球体7，中间体4开口端内孔上有螺纹，压环2旋入中间体4内，压紧阀座5，中间体4与阀体1、压环2与阀体1、阀座5之间通过O形圈8密封。可任意位置安装，密封可靠、启闭灵活、维修快捷方便。 

Claims (1)
