The problem of this technological scheme is, two standardized pipeline configurations can not be connected, it only can connect the end of one of them pipeline, and after connecting, still there is the discontinuous position of internal diameter at the position of its interface, easily cause the generation of turbulent flow.
For another example CN201152409Y disclosed " metal framework reinforced plastic composite pipe network ", its specific design scheme comprises: the inner layer sleeve having band boss, in inner layer sleeve, at least excircle is connected with the inner plastic melting of metal skeleton reinforced composite plastic pipeline end, pipe joint is connected with the plastic outer layer of metal skeleton reinforced composite plastic pipeline end and the boss outer peripheral surface melting of inner layer sleeve, pipe joint and inner layer sleeve melting connect as one and form an annular U type joint socket, annular U type joint socket by the plastic outer layer of metal skeleton reinforced composite plastic pipeline termination and inner plastic and the complete melting of pipeline end face coated, multiple tube is connected by pipe joint with multiple tube and forms pipe network.
The problem of this technological scheme is, after its inner layer sleeve (drawing reference numeral 1) is connected with the pipe joint at two ends, the internal diameter of inner layer sleeve is less than the internal diameter of pipe joint, define the rapid shrinking structure of internal diameter of the pipeline, after pipeline is connected, internal diameter is discontinuous, easily causes turbulent flow, increases the pressure of pipe interior, bring higher requirement to the bearing capacity of sealing and pipeline, easily bring pipeline burst and leakage.
For another example CN101248305B disclosed " pipe coupling ", its specific design scheme comprises: the holding element with sharp-pointed pipeline press-in edge, this press-in edge provides the sealing between tube gripping member and pipeline.Another kind of such joint comprises the tube gripping member with fittings body press-in edge, and this press-in edge provides the sealing between tube gripping member and fittings body.
The problem of this technological scheme is, pipeline interface organization is complicated, and inner caliber also exists contracting position suddenly, so also there is the problem of turbulent flow, pressure-bearing and sealing.
So based on foregoing, design a kind of sealing configuration good, the connecting duct joint that tube wall resistance is little, the pipeline making two internal diameters identical docks, and is the technical problems to be solved in the utility model.
