Description

球面硬密封蝶阀
技术领域
本实用新型涉及一种蝶阀,尤其涉及一种球面硬密封蝶阀。
背景技术
目前,蝶阀是一个广泛应用的流体输送的组件,随着经济的发展,特别是煤化工产业和装备制造业的发展。在气--固。液--固二相流中,对阀门提出新的要求:高温、高压、耐磨、耐腐蚀、耐冲刷、抗热循坏和零泄漏等。
现有技术中的蝶阀很难满足上述要求。
发明内容
本实用新型的目的是提供一种密封性好、操作方便灵活、使用寿命长、适应性强的球面硬密封蝶阀。
本实用新型的目的是通过以下技术方案实现的:
本实用新型的球面硬密封蝶阀,包括阀体,所述阀体内设有阀座、蝶板,所述蝶板通过阀杆安装在所述阀体上,所述蝶板与阀座之间的密封面为球形面,且为硬密封结构。
由上述本实用新型提供的技术方案可以看出,本实用新型实施例提供的球面硬密封蝶阀,包括阀体,所述阀体内设有阀座、蝶板,所述蝶板通过阀杆安装在所述阀体上,所述蝶板与阀座之间的密封面为球形面,且为硬密封结构。密封性好、操作方便灵活、使用寿命长,能适应高温、高压、耐磨、耐腐蚀、耐冲刷、抗热循坏和零泄漏等要求。
附图说明
图1为本实用新型实施例提供的球面硬密封蝶阀的侧面剖视结构示意图;
图2为本实用新型实施例提供的球面硬密封蝶阀的正面结构示意图。
图中:1、阀杆,2、阀体,3、阀杆,4、蝶板,5、阀座,6、阀杆的回转中心,7、球形面的中心。
具体实施方式
下面将对本实用新型实施例作进一步地详细描述。
本实用新型的球面硬密封蝶阀,其较佳的具体实施方式是:
包括阀体,所述阀体内设有阀座、蝶板,所述蝶板通过阀杆安装在所述阀体上,所述蝶板与阀座之间的密封面为球形面,且为硬密封结构。
所述阀杆的回转中心向一侧偏离所述球形面的中心。
所述蝶板为整体结构,所述阀座为无簧阀座,所述阀体为铸锻结构。
本实用新型的球面硬密封蝶阀主体采用铸锻结构,具有强制密封,密封面采用偏心式球面,可实现双向密封零泄漏。密封面之间无摩擦,起闭方便,而且,密封面的磨损有自动补偿功能。具有结构合理、重量轻、操作方便灵活、使用寿命长等特点,可以在现场操作亦可远距离程序控制、启闭速度快、耐磨、启闭灵活、使用寿命长等特点。它的结构特点是:蝶板为整体设计,蝶板密封面为球状体,阀体密封件阀座为无簧座阀座,两密封面之间存在一定的硬度差,使开启力矩更小,且蝶板具有偏心,使蝶板具有一定的补偿功能。
以上所述,仅为本实用新型较佳的具体实施方式,但本实用新型的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本实用新型披露的技术范围内,可轻易想到的变化或替换,都应涵盖在本实用新型的保护范围之内。因此,本实用新型的保护范围应该以权利要求书的保护范围为准。
