摘　　要：折叠封堵头是油气管道折叠封堵技术的关键设备。文章概述了油气管道不停输封堵换管的一般原理,阐述了折叠封堵技术的优势和主要应用领域,详细介绍了折叠封堵头的结构组成和工作原理。通过对720管径、529管径的现场封堵试验,验证了折叠封堵头的可行性,测定了封堵压力。The folding plugging head is the key equipment to plugging technology. In this paper, the basic principle of plugging technology with pressure conveying for the pipeline was summarized, advantages of the folded plugging technology and its main application fields were expounded, and the structural composition and working principle of the folding plugging head were introduced in detail. Through field plugging tests of DN 720 and DN529 pipes, the feasibility of folding plugging head was verified, and the plugging pressure was determined.
