Problems solved by technology

Since the thickness of the screw plug itself is not greater than that of the pipe base material, and its hollow exterior has a screw cap-shaped structure, it determines its characteristics of simple operation and poor plugging quality. On the one hand, the hollow structure is easy to use external force to make it fast. Shrinkage, directly block the foaming opening; on the other hand, even if the hot melt machine is hot-melted, it is only the welding of the plugging and threading part and the section of the foaming opening pipe, and due to human operation and other reasons, it is easy to cause welding defects, welding is not firm, etc. , plus the hollow structure of the plug, the thickness of the plug is smaller than the base material of the pipeline, and quality accidents such as cracking of the plug during the peristalsis of the pipeline may occur from time to time, which brings great hidden dangers to the operation of the pipeline network

Abstract

The invention relates to a hot-melt plug welding positioning press, and belongs to the field of pipeline processing equipment. The hot-melt plug welding positioning press comprises a handle, a pressure rod, a top plate, a support member, a positioning body, a mold, a positioning clamping member, and a bottom plate, wherein the handle, the pressure rod, the positioning body and the mold are sequentially connected from top to bottom, the top plate, the support member, the positioning clamping member and the bottom plate are sequentially connected from top to bottom, and the pressure rod vertically passes through the top plate. A pipeline material injection hole, a pipe fitting material injection hole, a hot-melt sleeve port material injection hole and an exhaust hole are accurately subjectedto hot-melt sealing by pressurization and pressure stabilization during advance positioning and hot-melt sealing, the tensile strength of a repairing part is high, the repairing part is not easy to damage, and a pipeline around the plugging part cannot be damaged during plugging, so that the service life of the plugged pipeline is prolonged.

Description

technical field [0001] The invention relates to the field of pipeline processing equipment, in particular to a hot-melt plug welding positioning press and a working method thereof. Background technique [0002] At present, due to work needs, many fluid transportation pipelines in China need to open holes in the pipelines and heat-melt them afterwards, such as urban central heating insulation pipelines, hot-melt joints at construction sites, insulation pipe fittings, long-distance oil pipelines and Other fluid conveying insulation pipes, etc. In order to ensure the tightness and service life of the pipeline, the sealing of the channel is very important. [0003] There are two main methods of sealing pipes, pipe fittings and hot-melt sleeve joints in today's technology. One is polyethylene plug (with a turnbuckle outside the hollow) to directly seal the injection hole and exhaust hole with external force; the other is One is the polyethylene plug (there is a turnbuckle outsi...
