Before the present invention finishes, do not see and adopt the pipe joint of the method manufacturing identical in urban Underground pipeline, to use with manufacture method of the present invention, the pipe joint of not seeing the method manufacturing identical with manufacture method of the present invention has sale on market, the pipe joint of also not seeing the method identical with manufacture method of the present invention and adopting this method to make is on the books in the literature.
Summary of the invention
The object of the present invention is to provide the product of a kind of pipe-joint manufacturing method and manufacturing thereof, need not to be subjected to an end dilated diameter of pipeline build the pipeline running-on and cause add the large pipeline manufacture difficulty, cause carrying and difficulty is installed, the puzzlement that causes cost to raise, very easily manufacturing, carrying and mounting pipe joint, realize the connection of pipeline, reduce construction costs.
For achieving the above object, the present invention adopts following technical proposals:
A kind of pipe-joint manufacturing method mainly comprises the steps:
The first step: by Rubber Extruder, make cylindric rubber ring, and it is vulcanized with vulcanizer;
Said rubber ring internal structure is the center line symmetry shape, oriented inside, the center of rubber ring is outstanding is trapezoidal locating piece, the trapezoidal base of said locating piece extends to form flat segments along the rubber ring inwall, and then to rubber ring outer wall and direction of both ends extension, extend to form the sealing lip sidewall along rubber ring inwall direction again, on said sealing lip sidewall, be provided with sealing lip to rubber ring center line and the extension of rubber ring direction of axis line, the sealing lip of the end of rubber ring has with rubber ring and is funnelform inclined-plane, be provided with port slot inner to rubber ring and that cave in the end in the outside of the end of said rubber ring, be provided with the dovetail groove that is the dovetail groove shape to cushion rubber center line and end at said rubber ring outer wall, the diameter of said flat segments is consistent with the external diameter of the pipeline that will connect;
Second step was installed on said rubber ring on the column type mould, and glue crosslinking agent is coated on the said rubber ring equably;
The 3rd step will be wrapped on the said rubber ring through the glass fibre that epoxy resin soaks into, and formed the glass fibre winding layer;
In the 4th step, the short glass fibre of cutting felt and the infiltration of said process epoxy resin is continued to be wrapped on the above-mentioned rubber ring that twines glass fibre, up to reaching desired thickness;
The 5th step, the surface of polyester felt after twining one deck, the skin of above-mentioned the 4th step formation is cut off, and with hairbrush that its brush is flat, form pipe joint;
The 6th step was heating and curing the aforementioned tube joint, and solidification temperature is 40 ℃-90 ℃, and the time is 1 hour;
In the 7th step, the manufacturing of pipe joint is finished in the demoulding.
In technique scheme, in the said first step, the sealing lip that extends at said cushion rubber center line and rubber ring direction of axis line can have the face with the rubber ring transverse cross-section parallel.
In technique scheme,, extend to form the dovetail groove that moves down of dovetail groove at the end direction of the center line of the oriented rubber ring in bottom of the dovetail groove of said rubber ring outer wall and rubber ring in the said first step.
In technique scheme, the hardness of said rubber ring is shore hardness 70-75.
Two pipelines are inserted along the two ends of said pipe joint, until reaching the connection that the said locating piece foundation of pipe joint of the present invention promptly can realize two pipelines.
In technique scheme, said dovetail groove and move down dovetail groove is to combine closelyr in order to allow said rubber ring and infiltration have between the glass fibre winding layer of epoxy resin, prevents horizontal sliding phenomenon.
In technique scheme, said to move down setting up of dovetail groove also be in order to reduce the wall thickness of rubber ring in said flat segments, to make the tubing that is connected tightr with combining of sealing ring.
The more said dovetail groove size of the cavity size of said port slot is bigger, can strengthen the adhesion between rubber ring and the glass fabric winding layer, guarantees that when press-fiting tubing the sealing ring end can not deviate from.
The effect of said sealing ring sealing lip is to keep good seal.When the pipeline on both sides inserts connector of the present invention, said sealing lip is subjected to the brute force extruding of pipeline, produce deformation, can realize the tight connection between the pipeline, when the liquid in the pipeline produces pressure, can press to tube surfaces to the rubber of seal lip, pressure is big more, and pressuring action is also big more.
The effect of said locating piece be the no-go nipple both sides tubing press-fit the position, it is asymmetric to avoid both sides to install.
The setting of said flat segments is the good combination that guarantees pipe joint and tube surfaces, guarantees the location of pipe joint.
The pipe joint product that adopts aforementioned tube joint manufacture method to be produced can be applied to steel pipe, cast iron pipe, plastic tube, pipe of concrete or glass reinforced plastic pipe, comprises that fiberglass yarn-clipping tube, fiberglass and polymer multiple tube, steel wire twine enhancing multiple tube and steel-plastics composite pipe etc.
The present invention has more following effects and good effect:
The invention provides the pipe joint that a kind of pipe-joint manufacturing method and this manufacture method are produced, an end dilated diameter that need not to be subjected at pipeline is built the pipeline running-on, and cause add the large pipeline manufacture difficulty, cause carrying and difficulty is installed, the puzzlement that causes cost to raise, can realize making easily, carrying and mounting pipe joint, realize the connection of pipeline, reduce construction costs.
