Abstract

苛刻工况用高性能蝶阀，包括阀体、阀杆、蝶板，阀杆穿过阀体与蝶板固定连接，在阀杆上套装填料组件，填料组件通过填料压盖固定密封，填料组件包括方填料，在方填料的上下两端反向设置V形填料A和V形填料B，V形填料A与填料压盖之间设置T形推块A，V形填料B的下端设置T形推块B，T形推块B的下端设置弹簧，弹簧与T形推块B之间设有弹簧座。本发明的有益效果是：在弹簧力的作用下，使得T形推块和V形填料相互卡紧，补偿填料因长期磨损产生的间隙，保证了阀杆处的密封性能。

Description

苛刻工况用高性能蝶阀
所属技术领域
本发明涉及一种阀门，特别是涉及一种蝶阀。
背景技术
目前使用的蝶阀，其阀杆填料密封一般采用填料压盖压紧填料组件，由于上部填料压盖的单向压紧，使上部填料的受力大，密封比压高，而下部填料受力小，出现密封比压不均匀的情况，长时间运行后，会发生填料组件磨损现象，产生间隙，引起阀杆处的泄漏。
发明内容
为了克服现有蝶阀的上述缺点，本发明提供一种阀杆密封能够实现自动补偿、无间隙配合的蝶阀。
本发明解决其技术问题所采用的技术方案是，苛刻工况用高性能蝶阀，包括阀体、阀杆、蝶板，阀杆穿过阀体与蝶板固定连接，在阀杆上套装填料组件，填料组件通过填料压盖固定密封，填料组件包括方填料、V形填料、T形推块、弹簧座和弹簧，在方填料的上下两端反向设置V形填料A和V形填料B，V形填料A与填料压盖之间设置T形推块A，V形填料B的下端设置T形推块B，T形推块B的下端设置弹簧，弹簧与T形推块B之间设有弹簧座。
本发明的有益效果是：在弹簧力的作用下，使得T形推块和V形填料相互卡紧，补偿填料因长期磨损产生的间隙，保证了阀杆处的密封性能。
附图说明
图1是实施例的结构示意图；
图2是图1中A处放大图。
图中：1.阀杆；2.蝶板；3.阀体；4.填料组件；5.填料压盖；6.T形推块A；7.V形填料A，8.方填料；9.V形填料B；10.T形推块B；11.弹簧座；12.弹簧。
具体实施方式
如图1、2所示，苛刻工况用高性能蝶阀，包括阀体3、阀杆1、蝶板2，阀杆1穿过阀体3与蝶板2固定连接，在阀杆1上套装填料组件4，填料组件4通过填料压盖5固定密封，填料组件4包括方填料8，在方填料8的上下两端反向设置V形填料A7和V形填料B9，V形填料A7与填料压盖5之间设置T形推块A6，V形填料B9的下端设置T形推块B10，T形推块B10的下端设置弹簧12，弹簧12与T形推块B10之间设有弹簧座11。
