Description

球阀弹性阀座
技术领域
本实用新型涉及一种球阀弹性阀座,特别适用于铸石球阀,属于球阀弹性阀座技术领域。
背景技术
目前,公知用于铸石球阀的阀座,阀座密封圈角度太大,与球体接触面积大,抱球报的紧,产生的力矩就大,阀座密封圈磨损加剧,而且启闭困难。
发明内容
本实用新型的目的在于解决上述已有技术存在的不足之处,提供一种结构设计合理、操作方便、密封性能好、使用寿命长的球阀弹性阀座。
本实用新型是通过以下技术方案来实现的:
球阀弹性阀座,特殊之处在于为密封圈结构,两端分别设有第一沟槽8,中部设有第二沟槽9,底部设有与球体4形成线密封的凸环10。
本实用新型球阀弹性阀座,结构设计合理,具有启闭省时省力、操作方便、密封性能好、使用寿命长。
附图说明
图1:安装有球阀弹性阀座7的阀体1结构示意图;
图2:本实用新型球阀弹性阀座的结构示意图。
图中:1、阀体,2、流入通道,3、排出通道,4、球体,5、上阀杆,6、下阀杆,7、球阀弹性阀座,8、第一沟槽,9、第二沟槽,10、凸环。
具体实施方式
以下参考附图给出本实用新型的具体实施方式,用来对本实用新型的构成做进一步的说明。
实施例1
本实施例的球阀弹性阀座应用于阀体1,阀体1的两端分别设有流入通道2、排出通道3,阀体1内的球体4两端分别连接有上阀杆5、下阀杆6,阀体1上设有与球体4配合使用的球阀弹性阀座7,球体4与球阀弹性阀座7形成密封结构,球阀弹性阀座7为两端分别设有第一沟槽8、中部设有第二沟槽9、底部设有与球体4形成线密封的凸环10的密封圈,第一沟槽8的作用是使其与第二沟槽9构成较小桥架,有利于阀座部分的弹性变形,在使用中处于阀体进口端的阀座,压力介质进入第二沟槽9、第一沟槽8中,迫使阀座紧贴球体进行密封,凸环10的作用是与球体4形成线密封,接触面积小,开关省时省力。
本实施例的球阀弹性阀座,结构设计合理,具有启闭省时省力、操作方便、密封性能好、使用寿命长。
