Description

多功能偏心旋转阀
技术领域
本发明涉及阀门机械领域，具体涉及一种偏心阀。
背景技术
目前现有的大多数阀门的阀体和球体的中心是同轴的，无偏心结构。阀门开启和关闭时密封面始终有摩擦，阀门开闭力矩大，阀门使用寿命短。另外阀座背后密封用O型圈或石墨密封，阀门使用范围受到温度限制，密封件也容易老化和破损，影响密封性能。CN203614769Ｕ（专利号ＺＬ201320800190.6）公开了一种偏心旋转的调节阀，其包括阀体，其中，还包括：半球形的阀芯，所述阀芯通过一柔臂偏心的连接于阀杆上；阀座，与所述阀芯匹配地设置于所述阀体内；所述阀芯，偏心的随所述阀杆转动，改变阻塞所述阀座的面积。其降低了闪蒸和空化问题，延长了调节阀的寿命，但是存在阀座和阀体之间有橡胶或石墨的密封圈，缺点1：密封圈容易挤压变形，特别是阀门长时间使用后，容易引起密封失效，阀门泄露。缺点2：密封圈的变形量影响阀座和阀芯的配合尺寸，装配难度增加。本发明阀体4和阀座2之间无密封圈，完全靠两者的金属本体密封，主要是提高配合件的光洁度和加工精度，装配配合尺寸精准,装配一次性成功率提高。
发明内容
为了解决上述技术问题，本发明设计了一种多功能偏心旋转阀，解决了阀
座和阀体密封的问题，扩大阀门的使用范围，提高了效率。
本发明的技术方案如下：
一种多功能偏心旋转阀，阀体和球体采用偏心结构，球体为半球形，阀杆和球体采用花键连接，阀座设在阀体进口处，阀座由螺纹座固定在阀体上，阀杆由上导套和下导套固定在阀体轴孔中，阀杆转动带动球体转动，实现阀门开启和关闭。阀杆由柔性石墨制成的填料密封；填料设在填料压板和填料箱内。填料压板通过第三螺柱与阀体固定连接，连接管件设于填料箱和阀体轴外侧，连接管件的一端通过第一螺柱与阀体固定连接，连接管件的另一端通过第二螺柱与液压执行器固定连接，液压执行器与阀体轴连接，并带动阀体轴旋转。阀座和螺纹座之间纯金属结合密封，无密封件。阀门利用偏心结构，开启时球体和阀座脱离，球体旋转90°到全开位置，关闭阀门时球体逆向旋转90°到阀座位置，实现密封。
更进一步，球体和阀座的密封面喷涂硬质合金层，提高了阀门的使用寿命。
与现有技术方案相比，本发明技术方案有益效果：
1.阀门开闭轻巧，节约了执行机构的成本。
2.阀座和螺纹座之间纯金属密封，无密封件，使用范围和工况不受影响。
3.密封面无摩擦，提高了阀门的使用寿命。
