Description

球形封头
技术领域
本实用新型涉及一种球形封头,属于封头技术领域。
背景技术
封头是石油化工、原子能到食品制药诸多行业压力容器设备中不可缺少的重要部件;封头是压力容器上的端盖,是压力容器的一个主要承压部件;封头的品质直接关系到压力容器的长期安全可靠运行;而常规的封头结构单一,无法满足各类压力容器和锅炉的需求。
发明内容
本实用新型的目的在于克服上述不足,提供一种适用范围广的球形封头。
本实用新型的目的是这样实现的:一种球形封头,所述球形封头包含有封头本体,所述封头本体的横截面为半环状结构。
与现有技术相比,本实用新型的有益效果是:
本实用新型将封头的横截面设置成半环状结构,从而使得其能够与压力容器或者锅炉贴合更为紧密,从而提高了封头的使用范围,增加了压力容器或锅炉的安全性能。
附图说明
图1为本实用新型球形封头的剖视图。
其中:
封头本体1。
具体实施方式
参见图1,本实用新型涉及的一种球形封头,所述球形封头包含有封头本体1,所述封头本体1的横截面为半环状结构。
