Abstract
The utility model relates to a pipe connector which is a flexible connector. A seal gasket is disposed at the identity interface connected with the pipe, binding hoops a and b pressing the seal gasket are disposed on the identity on both sides of the position where the seal gasket disposed, at least two through holes are disposed at the head of the identity interface, binding block is disposed at the through hole position which could make the diameter of the identity interface become small; the structure of the binding block is that flanges are disposed on both sides of the position of the through hole, flanges are connected with the corresponding ones by bolt and nut; the identity is a curved surface body; the identity interface at the position of the binding hoop a and the pipe are disposed with several connection pins. The structure of this model is simple, application range is wide, dismantlement and assemblage is convenient, cost is low and the sealing effect is good, therefore, this model could fit the expansion caused by heat and contraction caused by cold, stress changes, etc. The flexible connector of this pipeline is applicable for connection between metal pipe and metal pipe, plastic pipe and plastic pipe, cement pipe and cement pipe and other pipes of same materials.
Description
Technical field
The utility model relates to pipe coupling, is a kind of pipeline flexible joint.
Background technique
The pipeline of existing public gas (vapour), liquid conveying engineering is generally pipelines such as metal, plastics and cement.Adopt welding, sealing flange Connecting format for metallic conduit; Adopt bonding, sealing flange Connecting format for plastic pipe; Adopt the slush Connecting format for concrete duct.Adopt the metallic conduit or the bonding plastic pipe of welding to be not easy to maintenance; The metallic conduit, the plastic pipe that adopt sealing flange to connect require to make and the installation precision height, therefore, and the expense height; The concrete duct join strength that adopts slush to connect is poor, insecure, easily leaks.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of simple in structure, applied widely, easy accessibility, and cost is low, and good sealing effect can adapt to the pipeline flexible joint of the STRESS VARIATION of expanding with heat and contract with cold.
The technological scheme that solves its technical problem employing is: a kind of pipeline flexible joint, it comprises body, sealing gasket, its special way is: at the body jointing that is connected with pipeline sealing gasket is set, on the body of the both sides of sealing gasket position, be equipped with fastening hoop a and the b that compresses sealing gasket, head end at the body interface is provided with two ports at least, is provided with the fastener that body interface diameter is diminished in the port position.
The structure of described fastener is, is equipped with flange in the both sides of the port position of body interface, and flange is connected by bolts and nuts with corresponding flange.
Described body is a curved surface.
On the body interface of the described fastening hoop a position that compresses sealing gasket and pipeline, be provided with several connecting pins.
Pipeline flexible joint of the present utility model, on the body of the both sides of sealing gasket position, be equipped with fastening hoop a and the b that compresses sealing gasket owing to adopt, head end at the body interface is provided with two ports at least, be provided with the fastening body structure that body interface diameter is diminished in the port position, have simple in structure, applied widely, easy accessibility, cost is low, advantages such as good sealing effect.Because body is curved surface, can adapt to the expand with heat and contract with cold needs of STRESS VARIATION of pipeline.Because be provided with several connecting pins on the body interface of the fastening hoop a position of compressing sealing gasket and pipeline, it is more firm that the pipeline flexible joint is connected with pipeline.Pipeline flexible joint of the present utility model is applicable to being connected between metallic conduit and metallic conduit, plastic pipe and plastic pipe, concrete duct and concrete duct and the unlike material pipeline.
