Description

一种脱硫蝶阀
技术领域
本发明涉及阀门技术领域，特别是涉及一种脱硫蝶阀。
背景技术
现有技术中，脱硫蝶阀是作为开启、关闭和调节流体通道的一种阀门。在使用过程中，脱硫蝶阀必须满足腐蚀，磨损，流速，温度等几点要求，而目前应用于煤炭领域的脱硫蝶阀存在一些缺点，燃烧后的烟气中会出现一定量的氯离子和氯离子，管道中的颗粒物会沉积在阀口处，打开或闭合时增加了蝶板的磨损，从而也降低了密封性能。
发明内容
本发明主要解决的技术问题是提供一种脱硫蝶阀，能够提高耐腐蚀和耐磨性。
为解决上述技术问题，本发明采用的一个技术方案是：提供一种脱硫蝶阀，包括：阀杆、阀体和蝶板，所述蝶板的外围设置有一橡胶环，所述橡胶环的内壁为一倾斜面，所述橡胶环的外壁为齿形结构，所述橡胶环的外壁与阀体紧密贴合，所述阀杆上部与阀体接触部设置有第一密封圈，所述阀杆中部与阀体接触部设置有第二密封圈，所述第一密封圈与第二密封圈之间形成一腔体。
在本发明一个较佳实施例中，所述第一密封圈上设置有出气口。
在本发明一个较佳实施例中，所述第二密封圈的下方内置在橡胶环的外壁方槽内。
本发明的有益效果是：本发明采用蝶板和橡胶环一起转动的方式，减少磨损，改变密封圈的密封方式，且减少粉尘堆积，提高耐腐性。
附图说明
图1是本发明脱硫蝶阀的内部结构示意图；
图2是图1中A处所示的局部放大示意图。
附图中各部件的标记如下：1、阀杆；2、阀体；3、蝶板；4、橡胶环；5、第一密封圈；6、第二密封圈；41、倾斜面；40、方槽；50、出气口。
具体实施方式
下面结合附图对本发明的较佳实施例进行详细阐述，以使本发明的优点和特征能更易于被本领域技术人员理解，从而对本发明的保护范围做出更为清楚明确的界定。
请参阅图1和图2，本发明实施例包括：一种脱硫蝶阀，包括：阀杆1、阀体2和蝶板3，所述蝶板3的外围设置有一橡胶环4，所述橡胶环4的内壁为一倾斜面41，所述橡胶环4的外壁为齿形结构，所述橡胶环4的外壁与阀体2紧密贴合，所述阀杆1上部与阀体2接触部设置有第一密封圈5，所述阀杆1中部与阀体2接触部设置有第二密封圈6，所述第一密封圈5与第二密封圈6之间形成一腔体。
进一步说，所述第一密封圈5上设置有出气口50；所述第二密封圈6的下方内置在橡胶环4的外壁方槽40内。
本发明脱硫蝶阀在闭合时，蝶板3和橡胶环4一起转动，蝶板3和橡胶环4之间没有摩擦，因橡胶环4的外壁齿形结构与阀体2之间的接触面积小，而橡胶环4与阀体1之间略有摩擦，提高了耐磨性，另外因橡胶环4的内壁为一倾斜面，燃烧后的烟气中的颗粒物不会沉积在阀口处，减少了对阀口的腐蚀，提高了耐腐性，当脱硫蝶阀在打开时，橡胶环4与阀体1之间不会产生挤压磨损，闭合时第一密封圈5与第二密封圈6之间形成的气压腔体也随之释放，对密封圈也起到很好的保护作用。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
