Abstract

本实用新型公开了一种金属硬密封球阀,包括阀体(5),阀体(5)内部设有球体(8),阀体(5)两端设有阀盖(4),阀盖(4)与球体(8)之间设有阀座(11),球体(8)与阀座(11)的密封结合面处均设有通过超音速喷涂而形成的高强度硬质金属碳化钨层。本实用新型的有益效果:提高了密封性能,降低了加工难度,适合于高温、高压、含粉尘等苛刻的工作环境。

Description

金属硬密封球阀
技术领域
本实用新型涉及阀门,尤其涉及一种金属密封球阀。 
背景技术
当今国内外球阀通常由阀体、阀盖、阀座、阀座密封圈、阀杆、球体、弹簧、O形密封圈、驱动装置等部件组成,均存在着下列三大缺点:一是阀座与阀盖的密封采用橡胶O形密封圈密封,受橡胶材料的影响,使用温度范围只能控制在-29℃~120℃内;二是球体表面和阀座密封面的表面精度要求高,特别是吻合度要求高,尤其是硬密封球阀,精加工难度大;三是受介质腐蚀和温度影响,弹簧、O形圈和阀座密封圈很容易变形失效而使阀门产生内漏而报废。 
实用新型内容
针对现有的阀门的缺点,本实用新型提供一种新型的金属密封球阀。 
为了实现上述目的,本实用新型所采取的措施: 
一种金属密封球阀,包括阀体,阀体内部设有球体,阀体两端设有阀盖,阀盖与球体之间设有阀座,球体与阀座的密封结合面处均设有通过超音速喷涂而形成的高强度硬质金属碳化钨层。 
本实用新型的有益效果:提高了密封性能,降低了加工难度,适合于高温、高压、含粉尘等苛刻的工作环境。 
附图说明
图1本实用新型的结构示意图。 
具体实施方式
一种金属密封球阀,包括阀体5,阀体5内部设有球体8,阀体5两端设有阀盖4,阀盖4与球体8之间设有阀座11,球体8与阀座11的密封结合面处均设有通过超音速喷涂而形成的高强度硬质金属碳化钨层,以提高密封副的耐磨性能。本实用新型的有益效果:提高了密封性能,降低了加工难度,适合于高温、高压、含粉尘等苛刻的工作环境。 
本领域内普通的技术人员的简单修改和替换都是本实用新型的保护范围之内。
