Description
Technical field
The present invention relates to pipeline or tube connection piece technical field, especially a kind ofly be used for the adjustable prefastening sealing saddle joint that pipeline or tubing flexibly connect.
Background technique
It is the raw material once injection moulding that plastic inspection well adopts macromolecule resin, and split combines, and adopts with well casing to flexibly connect; Pipeline and well soil associated movement; Uniform settlement has well solved the uneven subsidence that traditional brick well and plastic pipe produced, and effectively prevents surface collapse.Ducts and pipes crisscross for urban sewage, and layout is complicated, and the connection request between main conduit and the bypass line is higher, if sealing is poor, engineering problem such as will cause leaking.Available technology adopting saddle joint connects trunk pipeline and branch road pipeline, the saddle seat of saddle joint and the fixed seal connection of trunk pipeline, and the branch road pipeline is inserted in the cylindrical shell of saddle joint; Belong to and flexibly connect; The end of the cylindrical shell of saddle joint is provided with O-ring seal, and O-ring seal is between cylinder inboard wall and branch road pipeline outer wall, and sealing effect is controlled by the magnitude of interference between the three; Existing structure causes sealing effect relatively poor; Three's size receives the product that different manufacturers produces and size error is bigger, after the three has assembled, does not reach desirable sealing effect.
Summary of the invention
The technical problem that the present invention will solve is: for solving the deficiency of existing technology; A kind of adjustable prefastening sealing saddle joint that pipeline or tubing flexibly connect that is used for is provided; Through the threaded adjusting trim ring from the cylindrical shell lateral inboard crush seal cushion rubber, O-ring seal receive the inclined-plane guiding and to the center extruding, thereby hold the branch road pipeline tightly; Reach the purpose of pretension, improve sealability.
The technical solution adopted for the present invention to solve the technical problems is: a kind ofly be used for the adjustable prefastening sealing saddle joint that pipeline or tubing flexibly connect; Comprise the cylindrical shell that connects bypass line; One end of cylindrical shell has the saddle body that connects the trunk pipeline; Cylinder body outer wall is set with the Saddle cushion that cooperates with the saddle body, and cylinder body outer wall is threaded and is used to compress the nut of Saddle cushion, and the end away from the saddle body on the described cylindrical shell is provided with O-ring seal and the trim ring that is used for fixing O-ring seal; The bi-side of described O-ring seal have at least one to be the inclined-plane of outer ring width less than inner race width; Described barrel port place and trim ring are formed the annular groove of the O-ring seal that holds, and the diameter at barrel port place is greater than cylinder internal diameter, and the port of cylindrical shell has the hypotenuse corresponding with one of them inclined-plane of O-ring seal with the inwall transition position; Trim ring have the screw section that is threaded with the cylindrical shell outer ring and in the cylindrical shell lateral compressed part of side compression O-ring seal, the joint that also has connecting thread portion and compressed part.Hypotenuse on the cylinder inboard wall plays leading role, holds pipeline or the tubing that is sleeved in the O-ring seal tightly thereby O-ring seal is pushed to the center.
Improve guide effect further, the bi-side of described O-ring seal are the inclined-plane, and the O-ring seal sectional shape is the symmetrically arranged isosceles trapezoids in two inclined-planes, and the compressed part of described trim ring is the hypotenuse corresponding with the O-ring seal inclined-plane with the joint of O-ring seal.Hypotenuse on the trim ring and the hypotenuse acting in conjunction on the cylinder inboard wall better make O-ring seal push to the center, improve sealing effect.
For improving the sealing of O-ring seal, the inner ring of described O-ring seal is provided with at least one circle projection.
Concrete, described number of slugs is two, the projection cross section is circular arc.
Be sleeved in the O-ring seal pipeline or tubing and be easy to insert and be difficult to extract for making, the inner ring of described O-ring seal is provided with at least one circle barb-shaped lip limit.
Concrete, described barb-shaped lip limit quantity is two.
The invention has the beneficial effects as follows: of the present invention to be used for the adjustable prefastening sealing saddle joint structure that pipeline or tubing flexibly connects simple; Novel; Be easy to make, the side compression O-ring seal in the cylindrical shell lateral of the position through the threaded adjusting trim ring makes O-ring seal push to the center through hypotenuse on the cylinder inboard wall and/or the hypotenuse on the trim ring; Thereby reach the effect of pretension, improve sealing effect.When dismounting, unscrew trim ring and make O-ring seal lax, so that the dismounting of branch road pipeline.
