Technical Problem
[0003]本实用新型的目的在于提供一种软管管壁质量检测装置，以解决现有的胶管检测设备无法对内部存在损伤的问题进行检测的技术问题
Benefits of technology
首先，外力驱动伸缩杆轴向移动时，锁止在杆上的膨胀圈随杆移动并受到固定限位块端面的轴向挤压，迫使膨胀圈产生径向膨胀变形，从而与待检测软管两端内壁形成紧密密封；同时，集成于任意一个伸缩杆内部的空气流道能将供压管路的压力传递至已密封的软管内部空间。实现了对软管两端快速、可靠的内壁密封和内部加压，对软管的气密性和抗压性进行检测，更为有效的鉴别出管壁存在的漏气和破裂风险，达到了无需外部夹具夹持管壁即可建立密闭检测腔室，并能向腔内稳定输送检测压力的技术效果。有利于解决传统软管检测中因外夹密封易损伤管壁、密封不严导致泄露或难以适配不同管径等问题，为无损、高效、通用性强的管壁质量（如耐压、泄露）检测提供了核心结构基础，不仅如此，本实用新型采用加压空气来对软管进行检测，相较于水密封，不容易造成微漏未识别和废水排放的技术问题。
