双阀板单轴四连杆偏心蝶阀
技术领域
本发明涉及一种偏心蝶阀，具体的说是一种双阀板单轴四连杆偏心蝶阀，属于蝶阀结构技术领域。
背景技术
现有技术中，一般由两个台阀组成阀组，中间通氮气密封。如台阀采用高性能密封蝶阀会导致成本过高，如采用普通风阀则会泄漏太大，耗费氮气太多，使用成本太高。
本发明是将2台阀组成的阀组简化为一台阀，同时提高了密封性能，阀门成本和用户的使用成本大幅度下降。阀门体积小，重量轻。采用四联杆机构阀门扭矩小，密封性能可靠。该阀主要用于化工或环保行业尾气放散场合。
发明内容
本发明的目的在于克服上述不足之处，从而提供一种双阀板单轴四连杆偏心蝶阀，通过四连杆机构带动阀板运动，避免了运动过程中阀板与阀体干涉，同时提高了密封性能。
按照本发明提供的技术方案，双阀板单轴四连杆偏心蝶阀包括阀体、主阀座、副阀座、主阀板、副阀板、驱动轴、曲柄、牵引板和吊架，其特征是：阀体内横向设有驱动轴，驱动轴的两端伸出阀体并连接轴承座；驱动轴中部固接曲柄，曲柄上端通过第一销轴转动连接牵引板，牵引板后端通过第二销轴转动连接连杆，连杆下端通过第三销轴转动连接吊架，吊架通过螺栓固定在阀体上；牵引板前端通过螺栓连接主阀板，主阀板前端通过多个连接组件连接副阀板；阀体内侧壁从内向外依次焊接主阀座和副阀座，主阀板位于主阀座内侧并能够与主阀座密封配合，副阀板位于副阀座内侧并能够与副阀座密封配合。
进一步的，阀体和驱动轴之间设有填料，填料外侧设有填料压盖将填料压紧。
进一步的，连接组件包括连接螺栓和锁紧螺母，连接螺栓上连接锁紧螺母。
本发明与已有技术相比具有以下优点：
本发明结构简单、紧凑、合理，工作稳定可靠，通过四连杆机构带动阀板运动，避免了运动过程中阀板与阀体干涉，同时提高了密封性能。
附图说明
图1为本发明主视图。
图2为本发明侧视图。
附图标记说明：1-阀体、2-主阀座、3-副阀座、4-主阀板、5-副阀板、6-驱动轴、7-曲柄、8-第一销轴、9-牵引板、10-吊架、11-轴承座、12-填料压盖、13-填料、14-连杆、15-第二销轴、16-第三销轴、17-连接螺栓、18-锁紧螺母。
具体实施方式
下面本发明将结合附图中的实施例作进一步描述：
如图1~2所示，本发明主要包括阀体1、主阀座2、副阀座3、主阀板4、副阀板5、驱动轴6、曲柄7、牵引板9和吊架10。
阀体1内横向设有驱动轴6，驱动轴6的两端伸出阀体1并连接轴承座11。阀体1和驱动轴6之间设有填料13，填料13外侧设有填料压盖12将填料13压紧。
驱动轴6中部固接曲柄7，曲柄7上端通过第一销轴8转动连接牵引板9。牵引板9后端通过第二销轴15转动连接连杆14，连杆14下端通过第三销轴16转动连接吊架10，吊架10通过螺栓固定在阀体1上。
牵引板9前端通过螺栓连接主阀板4，主阀板4前端通过多个连接组件连接副阀板5。阀体1内侧壁从内向外依次焊接主阀座2和副阀座3，主阀板4位于主阀座2内侧并能够与主阀座2密封配合，副阀板5位于副阀座3内侧并能够与副阀座3密封配合。
所述连接组件包括连接螺栓17和锁紧螺母18，连接螺栓17上连接锁紧螺母18，通过锁紧螺母17将连接螺栓17与主阀板4和副阀板5锁紧。
本发明的工作原理是：在工作时，外部驱动机构连接驱动轴，驱动轴转动带动曲柄转动，曲柄又带动牵引板前后运动，牵引板随之带动连接成一体的主阀板和副阀板密封或开启阀体。本发明通过四连杆机构带动阀板运动，避免了运动过程中阀板与阀体干涉，双层阀板结构大大提高了阀体密封性能。
