Abstract
本实用新型提供的输气管线管口封堵密封圈，属于输气管道封堵技术领域。主要解决现有技术管道封堵费工费料且容易渗漏气体的问题，包括密封圈本体，所述密封圈本体的横截面呈U型，且U型开口朝内；密封圈内孔的直径与堵板凸台外圆直径匹配，当压圈将密封圈本体压缩时，其向外挤压变形并紧贴在管道内壁上，从而起到密封封堵作用。
The utility model provides a sealing ring for sealing an opening of a gas transmission pipeline, which belongs to the technical field of gas transmission pipeline sealing. It mainly solves the problems of the prior art that pipeline plugging is labor-intensive and easy to leak gas, including the seal ring body, the cross section of the seal ring body is U-shaped, and the U-shaped opening faces inward; the diameter of the inner hole of the seal ring Matching the diameter of the outer circle of the boss of the blocking plate, when the pressure ring compresses the body of the sealing ring, it will be deformed outwards and tightly attached to the inner wall of the pipe, thus playing a role of sealing and blocking.
Description
技术领域technical field
本实用新型属于输气管道封堵技术领域，具体涉及输气管线管口封堵密封圈。The utility model belongs to the technical field of gas transmission pipeline plugging, in particular to a sealing ring for gas transmission pipeline mouth sealing.
背景技术Background technique
目前，输气管线管口需要封堵时采用橡胶气囊充气堵塞管道，然后用砖、水泥砌墙封堵。此种方式封堵存在的问题：使用砖、水泥砌墙时费工、费料、施工场地开挖空间工作量大；砌墙后气囊不容易取出；封堵后封堵体容易渗漏气体。At present, when the mouth of the gas pipeline needs to be blocked, a rubber air bag is used to inflate the pipe to block the pipeline, and then to block it with bricks and cement. Problems in this way of sealing: when using bricks and cement to build walls, it takes a lot of labor and materials, and the excavation space of the construction site is large; the air bag is not easy to take out after the wall is built; the sealing body is easy to leak gas after sealing.
发明内容Contents of the invention
本实用新型的目的克服现有技术的不足，提供输气管线管口封堵密封圈。The purpose of the utility model is to overcome the deficiencies of the prior art, and to provide a seal ring for sealing the mouth of the gas pipeline.
本实用新型为解决上述技术问题而采取的技术方案是：The technical scheme that the utility model takes for solving the problems of the technologies described above is:
输气管线管口封堵密封圈，包括密封圈本体，所述密封圈本体的横截面呈U型，且U型开口朝内；密封圈内孔的直径与堵板凸台外圆直径匹配，当压圈将密封圈本体压缩时，其向外挤压变形并紧贴在管道内壁上，从而起到密封封堵作用。The sealing ring for the mouth of the gas pipeline includes a sealing ring body, the cross section of the sealing ring body is U-shaped, and the U-shaped opening faces inward; the diameter of the inner hole of the sealing ring matches the outer diameter of the boss of the blocking plate, When the pressure ring compresses the body of the sealing ring, it is extruded and deformed outwards and clings to the inner wall of the pipeline, thus playing a role of sealing and sealing.
所述密封圈本体采用塑性材料制作。The sealing ring body is made of plastic material.
本实用新型与现有技术相比，具有以下有益效果：Compared with the prior art, the utility model has the following beneficial effects:
由于本实用新型采用横截面呈U型的塑性密封圈本体，其在受压变形过程中紧贴管道内壁，从而起到密封封堵作用，封堵后不易渗漏气体。Since the utility model adopts a plastic sealing ring body with a U-shaped cross section, it clings to the inner wall of the pipeline during the compression deformation process, so as to play a role of sealing and sealing, and it is not easy to leak gas after sealing.

图中：1—密封圈本体；1-1—凹槽；1-2—横截面；2—密封圈内孔。In the figure: 1—the body of the sealing ring; 1-1—the groove; 1-2—the cross section; 2—the inner hole of the sealing ring.
具体实施方式Detailed ways
如图1和图2所示，输气管线管口封堵密封圈，包括密封圈本体1，所述密封圈本体1的横截面1-2呈U型，且U型开口朝内；密封圈内孔2的直径与堵板凸台外圆直径匹配，当压圈将密封圈本体1压缩时，凹槽1-1变形向外挤压紧贴在管道内壁上，从而起到密封封堵作用。As shown in Fig. 1 and Fig. 2, the sealing ring of the mouth of the gas transmission pipeline includes a sealing ring body 1, the cross section 1-2 of the sealing ring body 1 is U-shaped, and the U-shaped opening faces inward; the sealing ring The diameter of the inner hole 2 matches the diameter of the outer circle of the boss of the blocking plate. When the pressure ring compresses the sealing ring body 1, the groove 1-1 is deformed and squeezed outwards to cling to the inner wall of the pipe, thus playing a role of sealing and blocking .
所述密封圈本体1采用塑性材料制作。The sealing ring body 1 is made of plastic material.
工作过程：work process:
本实用新型在使用时，在进行输气管线管口封堵时，将密封圈本体1套在堵板上的凸台上，将堵板置于输气管口内，将压圈套于定位圈上，将螺栓拧入螺孔内，堵板和压圈将塑性密封圈本体1向外挤压令密封圈变形挤出并紧紧贴在管道内壁上，从而起到密封封堵作用。When the utility model is in use, when the mouth of the gas transmission pipeline is blocked, the sealing ring body 1 is set on the boss on the blocking plate, the blocking plate is placed in the mouth of the gas transmission pipe, and the pressure ring is placed on the positioning ring. Screw the bolts into the screw holes, and the blocking plate and the pressure ring will squeeze the plastic sealing ring body 1 outward to deform the sealing ring and stick it tightly to the inner wall of the pipeline, thus playing a role of sealing and blocking.
