AI Technical Summary
Technical Problem
传统无缝钢管连接时，通常在管道上设置法兰，然后在法兰之间设置密封垫，再通过螺栓固定连接，为了方便螺栓安装，密封垫上会开孔，螺栓安装后与密封垫存在缝隙，这会导致压力较高的流体在压力作用下从缝隙处缓慢外泄的问题出现
Benefits of technology
[0012]本实用新型的有益效果在于：本实用新型使用时，将锁紧盘A和锁紧盘B分别套设在钢管A和钢管B上，使锁紧盘A和锁紧盘B分别与法兰A和法兰B抵触连接，将密封圈A和密封圈B分别放入密封槽A和密封槽B与法兰A和法兰B接触连接，将压紧环左右两端分别插入密封槽A和密封槽B，使压紧环左右两端分别与法兰A和法兰B、密封圈A和密封圈B接触连接，将定位柱插入定位孔，使密封垫A与法兰A接触连接，将螺栓插入通孔后锁紧，使螺钉与锁紧盘A和锁紧盘B固定连接，锁紧盘A和锁紧盘B会夹紧法兰A和法兰B，使钢管A和钢管B固定，此时密封垫A夹紧在法兰A与法兰B之间，压紧环会挤压密封圈A和密封圈B，使密封圈A与压紧环和法兰A固定连接，使密封圈B与压紧环和法兰B固定连接；综上所述，本实用新型设置有多道密封结构，并且在安装时螺栓无需穿过密封件，密封件无需开孔，具备了高密封性的有益效果，解决了传统无缝钢管连接时，为了方便螺栓安装，密封垫上会开孔，螺栓安装后与密封垫存在缝隙，导致压力较高的流体在压力作用下从缝隙处缓慢外泄的问题。
