Description

一种新型球阀
技术领域
本发明涉及一种不锈钢球阀。
背景技术
不锈钢球阀由于材料采用不锈钢制成，与普通铜球阀相比，具有耐腐蚀、耐高温、硬度高、安全性能好等优点。但是，目前不锈钢球阀没有像铜球阀那样得到广泛应用，其价格高外，主要是密封性能比较差，造成球阀的使用寿命短。不锈钢球阀的阀体一般是钢管切割下来后用车床加工而成，钢管的厚度决定了球阀阀体与阀杆之间的接触面很小，用于密封的橡胶密封圈会易位，随着球阀使用过程中阀杆的频繁扭转，在此处很容易出现渗漏现象。
发明内容
本发明的目的是克服上述问题，通过改进结构，提供一种密封性能好、使用寿命长的球阀。
为实现上述目的，本发明采用下列技术方案：
一种新型球阀，包括阀体、阀芯、阀杆和手柄，阀体采用不锈钢制成，呈圆筒状，阀芯位于阀体内，手柄位于阀体外侧，阀杆穿过阀体，其内端与阀芯连接，外端与手柄连接，所述的阀体与阀杆之间设有密封座，密封座套在阀杆上，密封座与阀杆的接触处设置密封圈，密封座通过螺纹与阀体连接，所述的密封座上部伸出阀体外。
所述的密封座为圆筒形。
所述的密封座与阀体之间设置垫圈。
所述的阀杆上开有两道环形凹槽，每道环形凹槽中均有O形橡胶密封圈。
本发明的有益效果：通过增设密封座的方法，使它的密封性能有大幅度提高，也延长了球阀的使用寿命。同时，成本低，具有较高的使用价值。
图1是本发明提供的球阀的结构示意图。
具体实施方式
如图1所示，包括阀体1、阀杆3、阀芯2、手柄4和密封座5。阀体1采用不锈钢管制成，外形为圆柱状。球形的阀芯2位于阀体1内，控制本球阀的开关。阀杆3的内端与阀芯2连接，外端与手柄4连接。密封座5套在阀杆3上，并通过螺纹与阀体1连接。本实施例中，密封座5与阀体1之间设置垫圈7，以防止此处渗漏。密封座5与阀杆3有较大的接触面，其上部伸出阀体1。密封座5与阀杆3之间通过O形橡胶密封圈6密封。本实施例中，阀杆3上开有两道环形凹槽30，每道环形凹槽30中均有o形橡胶密封圈6。正是由于密封座5与阀杆3之间有较大的接触面，故可设置两道环形凹槽30，以增强此处的密封性能，克服了普通不锈钢球阀的渗漏现象。
