Description

Technical Field

[0001] The utility model relates to the technical field of protective equipment, in particular to a steel-plastic insulating joint press-fitting tool. Background Art

[0002] Steel-plastic insulated joints play an important role in sealing and preventing electrochemical corrosion in long-distance pipelines. In terms of structure, they are mainly composed of short sections, steel flanges, steel fixing rings, seals, insulating plates, insulating sleeves and filling insulating materials, so as to form a complete closed system. In terms of the type of seals, there are mainly three types of sealing structures: O-ring seals, U-ring seals and "O-shaped + U-shaped" composite seals. Although the sealing structures are different, they all have the same sealing principle. The sealing principle is: the sealing ring will produce elastic deformation under the action of the preload force applied by the outside world to achieve the required sealing force to ensure that the medium in the pipeline does not leak out. Steel-plastic insulated joints are also indispensable and important pipeline accessories in gas transmission and distribution and oil pipeline systems. They are mainly used in gas transmission and distribution systems and gas pressure regulating stations. Their function is to insulate and isolate the sections of the gas transmission and distribution pipelines, the gas pressure regulating stations and the transmission and distribution pipelines, protect them from electrochemical corrosion, extend their service life, and can also be directly buried for use;

[0003] Steel-plastic insulating joints not only have a wide range of applications, but also have very good effects and are very popular among users. The steel-plastic insulating joints currently on the market are difficult to fix and press fit the required pipes in gas transmission and distribution and oil pipeline systems, making them very inconvenient to use.
