Description

一种球阀
技术领域
本实用新型涉及阀门,具体涉及一种球阀。
背景技术
传统的球阀结构设计简单,往往采用硬密封阀座,即使采用安装软密封圈,也极易脱落;另外,阀座与阀芯的密封结合面易于进入杂质颗粒,从而发生密封面划伤现象,造成密封不严,同时也大大缩短球阀的使用寿命。
发明内容
针对现有的球阀的缺点,本实用新型提供一种新型的球阀。
为了实现上述目的,本实用新型所采取的措施:
一种球阀,包括阀体,阀体内设有阀芯和阀座,在阀座上与阀芯的连接处设有用于放置密封圈的凹槽。
在密封圈结合面的两侧开设有阻隔沟槽。
本实用新型的有益效果:密封性好,安全可靠,使用寿命长,利于推广应用。
附图说明
图1,本实用新型的主视剖面图;
图2,图1K处的放大图。
具体实施方式
一种球阀,包括阀体1,阀体1内设有阀芯2和阀座3,在阀座3上与阀芯2的连接处设有用于放置密封圈4的凹槽5,将软密封圈安装在凹槽中,不易脱落,密封性好,安全可靠。在密封圈4结合面的两侧开设有阻隔沟槽6,可以将进入密封面的较大杂质颗粒挡在阻隔沟槽中,减少密封面的摩擦和划伤,延长球阀的使用寿命。本实用新型的有益效果:密封性好,安全可靠,使用寿命长,利于推广应用。
本领域内普通的技术人员的简单更改和替换都是本实用新型的保护范围之内。
