Abstract

一种高压平衡蝶阀，包括阀体，阀体内安装有大蝶板，大蝶板上设有支座，阀杆固定安装在支座内，大蝶板上开有通孔，通孔内安装一小蝶板，小蝶板通过一传动机构与阀杆相连，阀杆上设置有齿轮轴段，传动机构包括齿轮、杠杆，齿轮与阀杆的齿轮轴段相啮合，杠杆一端开有U型卡口并与齿轮铰接，另一端与小蝶板铰接，齿轮及杠杆分别安装在齿轮支座及杠杆支座上，杠杆支座将杠杆分为左臂与右臂，左臂的长度小于右臂的长度。本发明的有益效果是：在大蝶板上设置小蝶板，在开启大蝶板的同时可以瞬时开启小蝶板，达到了瞬间平衡蝶板两侧压差的效果，减小了阀门开启时的扭矩。

Description

一种高压平衡蝶阀
技术领域
本发明涉及一种蝶阀，特别涉及一种开启时能够平衡两边压差的蝶阀。
背景技术
现有的蝶阀用于大口径管道时，特别在高压的工况下，管道内的介质对蝶板产生巨大压力，在蝶板开启时，由于蝶板两侧存在压差，阀杆所承受的扭矩很大，所配套的驱动装置需要的扭矩大，使得阀门的结构庞大，导致阀门开启不便。
发明内容
为了克服现有蝶阀的上述缺点，本发明提供一种结构简单且开启蝶板省力的高压平衡蝶阀。
本发明解决其技术问题所采用的技术方案是，一种高压平衡蝶阀，包括阀体，阀体内安装有大蝶板，大蝶板上设有支座，阀杆固定安装在支座内，大蝶板上开有通孔，通孔内安装一小蝶板，小蝶板通过一传动机构与阀杆相连，阀杆上设置有齿轮轴段。
传动机构包括齿轮、杠杆，齿轮与阀杆的齿轮轴段相啮合，杠杆一端开有U型卡口，杠杆的U型卡口一端与齿轮铰接，另一端与小蝶板铰接，齿轮及杠杆分别安装在齿轮支座及杠杆支座上，杠杆支座将杠杆分为左臂与右臂，左臂的长度小于右臂的长度。
本发明的有益效果是：在大蝶板上设置小蝶板，小蝶板通过一传动机构与阀杆连接，传动机构由齿轮和杠杆组成，杠杆的左臂长度小于右臂长度，在开启大蝶板的同时可以瞬时开启小蝶板，达到了瞬间平衡蝶板两侧压差的效果，减小了阀门开启时的扭矩。
附图说明
下面结合附图和实施例对本发明进一步说明。
图1是实施例的主视图；
图2是图1的俯视图。
图中：1.大蝶板；2. 支座；3. 阀杆；4. 销；5.齿轮；6. 杠杆；7. 小蝶板；8. 通孔；9.阀体；10. 杠杆支座；11.齿轮支座；12.齿轮轴段。
具体实施方式
如图1、2所示，一种高压平衡蝶阀，包括阀体9，阀体9内安装有大蝶板1，大蝶板1上设有支座2，阀杆3固定安装在支座2内，大蝶板1上开有通孔8，通孔8内安装一小蝶板7，小蝶板7通过一传动机构与阀杆3相连，阀杆3上设置有齿轮轴段12。
传动机构包括齿轮5、杠杆6，齿轮与阀杆3的齿轮轴段12相啮合，杠杆一端开有U型卡口，杠杆的U型卡口一端通过销4与齿轮5铰接，另一端与小蝶板7铰接，齿轮5及杠杆6分别安装在齿轮支座11及杠杆支座10上，杠杆支座10将杠杆分为左臂与右臂，左臂的长度小于右臂的长度。
开阀时，阀杆3逆时针旋转，带动齿轮5作顺时针转动，齿轮5上设置有销4，销4与杠杆一端的U型卡口铰接，齿轮5上销4的顺时针转动将杠杆6左端下压，由于杠杆6的左臂长度小于右臂长度，在杠杆6左端下压的同时杠杆6的右端快速提起，从而带动小蝶板7瞬时脱离大蝶板1上的通孔8，实现大蝶板1前后压力的瞬时平衡。
