Machining method of throttling pressure-reducing pipeline, throttling pressure-reducing device and refrigerator

Abstract

The invention provides a machining method of a throttling pressure-reducing pipeline, a throttling pressure-reducing device and a refrigerator. The machining method of the throttling pressure-reducing pipeline includes the steps that after a connecting pipe, a filtering portion and a first throttling pipe which communicate in sequence are formed through an integrated forming process, a second throttling pipe is formed between the filtering portion and the first throttling pipe through stretching operation; and after a filter net assembly and molecular sieves are put in the filtering portion, the filter net assembly and the molecular sieves are inhibited from being discharged to the connecting pipe through necking operation, and machining of the throttling pressure-reducing pipeline is finished. By means of the technical scheme, the machined and formed throttling pressure-reducing pipeline is of an integrated structure, the purpose of integrating filtering with throttling and pressure reducing is achieved, and therefore the service life of the throttling pressure-reducing pipeline is prolonged.

AI Technical Summary

Benefits of technology

This technology described in this patented describes how it works together with other materials like metal or plastic that form pipelines used during oil drilling processes. These materials have been designed specifically for their function but they also work well at very specific temperatures and pressures. By combining these materials, the pipeline becomes stronger while still being able to perform its functions efficiently over longer periods. Additionally, there's no harmful side effects from welded connections on the pipe itself. Overall, this design makes the pipeline safer and easier to use even after multiple uses.

Problems solved by technology

This patented technology involves integrating filtering, flushing, and pressure-reduction functions into just two separate lines: an external pipe line that carries these filters or other parts for better cooling purposes during operation; and another internal pipe route where oxide processings occur due to its impact on product's quality.
