Description

Internal resistance-free hot-melting socket connection structure

Technical Field

The utility model relates to a pipe connection spare technical field specifically is a hot melt socket joint connection structure without internal resistance.

Background

Plastics tubular product butt joint hot melt welding, tubular product inner wall welding kneck can form the cyclic annular protrusion structure of hot melt solidification, when the tubular product inner wall has cyclic annular protrusion structure, even if the attaches wall rivers of less flow, also can appear a funnel-shaped rivers that lasts at this position. Because the continuous funnel-shaped water flow completely seals the inner section of the vertical pipe and hinders the smooth air flow in the pipe, the continuous funnel-shaped water flow is called as a funnel-shaped water plug phenomenon, and as the height of the vertical drainage pipe is increased, the drainage capacity is reduced due to the increase of the ventilation resistance of the system; the funnel-shaped water plug is one of the main reasons for the great reduction of the drainage capacity of the system. In riser systems where the "funnel plug" phenomenon also exists, the higher the floor height, the greater the magnitude of the drop in drainage capacity. Through comparison of test results of the Hyuna experiment tower and the Hunan university experiment tower, the drainage capacity is reduced by 60% -65%, and the key problem is that a professional welder is needed to guarantee various technical quality requirements during pipeline welding and installation, but the construction drainage pipe works in the air and machines are not used, so that the quality and the safety of a pipeline system cannot be guaranteed at all when a hot plate is heated and manually butted by workers at the domestic construction site. Therefore, the hot melting socket connection structure without internal resistance is provided.
