The utility model discloses a new type of sealing device for pipe mouth, which comprises a sealing end seat with no less than two fixed holes at the edge. The middle part of the sealing end seat is a depression structure directed towards the pipe mouth, and a convex surface is formed at the bottom. A rubber sealing column with an integrated structure is arranged around the convex surface, and a threaded structure is arranged around the rubber sealing column. The structure of the utility model is simple, and the weight of the base and the cost of raw materials are not increased while the base is strengthened by the base depression. The use of the rubber sealing column, especially its external thread structure, can greatly increase the sealing effect for the reserved pipe opening, and the rubber sealing column is pushed into the reserved pipe opening under the external force, and the base with its integral structure is used for fixed sealing. The contact with external environment is small, which greatly reduces the probability of oxidation or weathering, and plays a great role in prolonging the service life and improving the sealing effect time.

技术介绍
随着社会的发展,尤其是科学技术的进步,大大促进了社会生产力的飞速发展。尤其是制造业的飞速发展,使得许多领域的多种异形结构部件越来越多,尤其在一些设备管路上体现更为凸显;在前期的设计制造过程中都会预留一些后期设备工艺延续或者配套设备的连接预留管口;诸多的预留管口在未启用之前,需要进行有效的封端;现有的封端多采用如图1所述的结构,即在管路系统8上设置有预留管口10,预留管口10外端口上该有水平面封端盖11,水平面封端盖11边缘通过内穿紧固螺栓9与管路系统8上的预留螺孔紧固,其中水平面封端盖11与预留管口10外端直接设置有密封胶垫12。上述的密封结构,在设备运行初期可以起到一定的封堵作用,但是随着社会运行过程的震动导致的螺栓连接松动,以及密封胶垫12的弹性老化等问题的出现,封堵效果就会表现的越来越差,无法达到预期效果,尤其是对于封端有腐蚀性的液体来说,因为封堵结构松动而腐蚀液体外漏的现象,更是不确定危险性很大。因此,改进管口封堵结构,达到提供封端效果及延长使用寿命,是一个值 ...
