Processing machine for inner liner on end face of pipeline flange

Abstract

The invention provides a processing machine for an inner liner on the end face of a pipeline flange. According to the technical scheme, the processing machine is mainly composed of parallel guide rods(1), a connection base (2), a nut (3), a machine base (4), a center shaft (5), a transmission gearwheel (6), a bearing (7), a flat key (8), a connection shaft pinion (9), a vent cover (10), a cuttingmechanism (11), a framework (11-1), a tool apron (11-2), a tool apron guide rod (11-3), a tool apron adjusting screw rod (11-4), an adjusting hand wheel (11-5), a cutting tool (11-6), a jackscrew (11-7), a belt wheel (12), a triangle belt (13), a motor (14), a motor base (15), a manual rocking handle (16), a connection rod (17), a pressing plate (18), the inner liner (19) and a steel flange (20).The processing machine has the beneficial effects that the structural design is reasonable and practical, leakage cannot be generated in long-time use, safe production is ensured, and the remarkableeconomic benefits and social benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of pipeline inner linings, in particular to a processing machine for inner linings of pipeline flange end faces. Background technique [0002] In order to improve the service life of various pipelines, technicians invented the technology of lining pipes and pipe fittings with plastic, so that the inner walls of the original pipes and pipe fittings are covered with anti-corrosion and wear-resistant inner linings, and the conveying medium does not directly contact the original pipes. , the original pipeline is no longer corroded and worn by the conveying medium, thereby improving the service life of the pipeline. In order to achieve the purpose of anti-corrosion and wear-resisting, the plastic pipe that needs to be lined must have continuity in the pipe, and the plastic-lined technology of pipe fittings (elbows, tees, etc.) has been invented, so that the inner wall of the pipe fittings is also anti-corrosion a...

AI Technical Summary

Problems solved by technology

The plastic-lined pipe fittings form a plastic-lined layer through the shape of the mold. The plastic liner formed by heating and turning-out is on the basis of the inner-lined pipe. It turns out that the pipe wall is increasing and the outward thickness is thinning. From the cross-section, a trapezoidal surface is formed. The lining surface of the plastic-lined pipe fittings is uneven due to the uneven heat dissipation temperature of the mold and the plastic shrinkage is inconsistent.

After the connection surface is fastened and installed by bolts, the stress on the lining surface will be uneven. Although there will be no leakage in the short term, the ambient temperature, medium and pressure will change during the long-term use, storage and transportation of the pipeline. The surface is pr
