in conclusion, how to ensure the tightness between the pipeline and the inspection well becomes an urgent problem to be solved by researchers in the field.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: how to ensure the tightness of the pipeline and the inspection well;
in order to solve the technical problem, the utility model discloses a following technical scheme:
the utility model relates to a pipeline and inspection shaft sealing connection structure, include: an inspection well; the end part of the pipeline is sleeved with a transition joint and is inserted and connected with a medium flow through hole of the inspection well through the transition joint; annular chambers are arranged on the inner wall and the outer wall of the transition joint; the sealing ring is arranged in the cavity and is abutted against the corresponding medium flow through hole or the outer wall of the pipeline to realize sealing;
in this scheme, the transition joint cover is established at pipeline tip, all is provided with the cavity of placing the sealing washer on transition joint inner wall, the outer wall, and the sealing washer has realized transition joint and pipeline, transition joint and medium circulation hole's sealing connection.
In order to realize that the transition joint can be sleeved at the end part of the pipeline and follows the movement of the pipeline, the utility model adopts the technical scheme that a ring body which is propped against the end part of the pipeline is arranged on the transition joint; the inner diameter of the ring body is larger than the diameter of the inner hole of the pipeline and smaller than the outer diameter of the pipeline;
so, the body can offset with the terminal surface of pipeline, makes transition joint insert to the medium flow through the pipeline through the ring body in can following the pipeline, and annular internal diameter is greater than pipeline hole diameter, sets up like this and does not influence the medium flow through in the pipeline.
In order to better insert the transition joint with the pipeline and the medium circulation hole, the utility model adopts the sealing ring with an inclined sealing inclined plane; the included angle between the sealing inclined plane and the outer wall of the pipeline or the inner wall of the medium circulation hole is a, and a is an acute angle;
be the acute angle design between sealed inclined plane and pipeline or the medium flow through-hole, be convenient for like this the transition joint insert to the medium flow in the hole and be convenient for the pipeline insert to the transition joint, when needs will seal inclined plane, pipeline, medium flow through-hole three and separate, need produce great pulling force, need trun into contained angle a to the obtuse angle promptly, make sealed inclined plane, pipeline, medium flow through-hole three connect inseparabler like this.
Compare and be the flexible piece in traditional crossover sub, the utility model discloses a crossover sub is the injection molding, and the injection molding can be more convenient be connected with pipeline, medium flow hole.
The utility model has the advantages that: the utility model relates to a pipeline and inspection shaft sealing connection structure, the transition joint cover is established at the pipeline tip, all is provided with the cavity of placing the sealing washer on transition joint inner wall, the outer wall, and the sealing washer has realized the sealing connection of transition joint and pipeline, transition joint and medium circulation hole.
