Skirt structure of pressure vessel

The utility model discloses a skirt structure of a pressure vessel, which relates to the technical field of pressure vessels, the pressure vessel comprises an end socket, the diameter of the skirt is smaller than the length of the long axis of the end socket, so that the included angle theta between the skirt and the end socket is larger than or equal to 60 degrees. The welding space can be enlarged, and the welding seam quality is guaranteed; when the equipment bears temperature and pressure circulation, a good anti-fatigue effect is achieved; and meanwhile, when the equipment works in a high-temperature and transverse wind vibration environment, the equipment has relatively high bearing and stability. 本实用新型公开了一种压力容器的裙座结构，涉及压力容器技术领域，压力容器包括封头，裙座直径小于封头长轴长度，以使裙座与封头之间夹角θ≥60°。本实用新型能够增大焊接空间，保证焊缝质量；当设备承受温度和压力循环时，有良好的抗疲劳效果；同时能够使设备在高温和横向风振环境中工作时，有较高的承载和稳定性。
