Description

Technical Field

[0001] The utility model relates to the technical field of pipeline alloy valves, in particular to a pipeline alloy valve with a temperature-sensing antifreeze function. Background Art

[0002] As we all know, pipeline alloy valves are valves used in pipeline systems, usually made of alloy materials, to control the flow and pressure of fluids (liquids, gases, or powders) in pipelines. Pipeline alloy valves have excellent properties such as high temperature resistance, corrosion resistance, and wear resistance, and are suitable for long-term use in harsh environments.

[0003] Utility model patent publication number CN202152873U discloses an antifreeze valve, comprising a valve body and a valve cover. These valve body and valve cover, when flange-connected, form a pressure chamber, the walls of which are lined with a rubber buffer layer. This solution addresses the problem of existing valves cracking due to freezing. By lining the valve's pressure chamber with a rubber buffer layer, the patent reduces the chamber volume by approximately 1 / 3 to 2 / 3, correspondingly reducing the expansion force caused by frozen water. Furthermore, the rubber buffer layer mitigates the expansion force of frozen water, further preventing valve cracking.

[0004] However, the existing pipeline alloy valves still have certain shortcomings: although the existing pipeline alloy valves use components such as lining layers to improve the freezing and pressure resistance of the valve cavity, due to the flow characteristics of the fluid, the fluid will still circulate inside the pipeline, thereby causing the subsequent pipelines and valves to continue to freeze.
