According to the pot cover assembly, the top surface cover and the lining cover are integrally formed, so that the lining cover and the top surface cover can be processed at the same time through one-time processing, use of a pair of molds is reduced, the step of follow-up assembly of the top surface cover and the lining cover is omitted, meanwhile, the number of parts is reduced, the overall processing and manufacturing difficulty of the pot cover assembly is greatly reduced, and the manufacturing cost is saved. The side cover is fixedly clamped with the lining cover and is not connected with the top surface cover, so that a complicated fixing structure does not need to be arranged on the top surface cover, the smoothness of the top surface cover is improved, and the probability that flow marks appear on the top surface cover in the injection molding process can be further reduced.

Chemical strengthening method of flexible glass and chemically strengthened flexible glass
The invention relates to the technical field of glass, in particular to a chemical strengthening method of flexible glass and the chemically strengthened flexible glass. The chemical strengthening method of the flexible glass comprises the following steps: pretreating the flexible glass to obtain pretreated flexible glass; the pretreated flexible glass is preheated, and preheated flexible glass is obtained; the preheated flexible glass is placed in chemical strengthening pure sodium molten salt to be subjected to chemical strengthening treatment and then cooled, and chemically strengthened flexible glass is obtained; the pretreatment comprises the following steps: carrying out ultrasonic treatment on the flexible glass in a sodium hydroxide alkaline solution with the concentration of 4-12mol / L; the flexible glass comprises the following raw materials in percentage by mole: 0-3% of Na2O and 8-10% of Li2O. The strength of the flexible glass can be effectively improved, and damage of stress concentration to the surface of the glass can be overcome; the chemically strengthened flexible glass shows excellent performance in bending strength, drop pen impact, 300,000 times of static bending and the like.

ActiveCN222526560UGuaranteed mechanical strengthGuaranteed StrengthPump componentsPumpsImpellerWeld seam
The embodiment of the utility model discloses a narrow-flow-channel impeller structure and a compressor. The narrow-flow-channel impeller structure comprises a cover disc, blades, a first spigot and a shaft disc. The cover disc and the blades are of an integrated structure, the mechanical strength of the narrow-flow-channel impeller structure is guaranteed, in the manufacturing process of the narrow-flow-channel impeller structure, the whole formed by the cover disc and the blades can be positioned through the first seam allowance and the rotary disc, then a circle of full welding can be formed at the first seam allowance, and a welding groove formed in the shaft disc is combined, so that the narrow-flow-channel impeller structure is manufactured. The blades close to the outlet side can be subjected to slotting welding through the welding grooves. By means of the arrangement, TIG + SMAW welding can be used for completing preparation of the narrow-flow-channel impeller structure, the strength of the narrow-flow-channel impeller structure is guaranteed, sinking weld meat is good, burnthrough and non-fusion are avoided, all blade weld joints are qualified in flaw detection, the appearance quality is good, and the production efficiency is high.
