FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
As shown in figure 1, the sealing device for the socket-type flexible connection concrete prefabricated pipe joint comprises a sealing ring arranged at a pipe joint, wherein the sealing ring comprises a sealing ring body 1 and an annular sealing sheet 2, the sealing ring body 1 is of an annular structure, a plurality of annular sealing bulges 3 are arranged on the inner ring of the sealing ring body 1, the annular sealing sheet 2 is further arranged on one side of the sealing ring body 1, the sealing ring body 1 is used for being sleeved at the end of a pipe socket, and the annular sealing sheet 2 is used for being clamped between the pipe joints.
The sealing ring disclosed by the utility model adopts a special-shaped structure, the width of the sealing ring body 1 is the same as the inserting length of a pipeline, the sealing ring body 1 is in a conical structure with one large end and the other small end, the inner wall of the sealing ring body 1 is a plane, and the outer wall is an inclined plane. One end of the sealing ring body is provided with an annular sealing sheet, the annular sealing sheet 2 is arranged at the smaller end of the sealing ring body, the width of the annular sealing sheet 2 is the same as the thickness of the pipeline interface, the end face of the larger end of the sealing ring body 1 is provided with an annular telescopic groove 4, the annular sealing sheet is arranged at the end part of the pipeline interface, and when the pipeline is spliced, the annular sealing sheet is clamped and fixed so as to fill the pipeline interface gap. The annular telescopic groove 4 can enable the sealing ring body to be extruded and deformed more easily, so that the sealing ring pipeline is ensured to be contacted closely.
In addition, the annular sealing bulges 3 are uniformly distributed on the inner wall of the sealing ring body, and the distance between the annular sealing bulges is 0.3-0.8 cm. The annular sealing bulge can form a multi-sealing structure on the inner wall of the sealing ring, so that the sealing is more reliable.
The present invention is not limited to the above preferred embodiments, but rather, any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the scope of the present invention.
