Abstract

The invention discloses a straight tube capillary used for refrigeration fittings and a processing method thereof, which comprises at least two sections of tube bodies and a welding seam protection device, which is detachable and tightly held at the welding seam between the welding sections ; The welding seam protection device is equipped with an adjustment connection device, which is used for the fixed connection between two adjacent sections of straight capillary tubes connected as a whole. The method includes: a. material selection; b. welding connection of the pipe body; c. installing the adjusting connection device on the lower end plate; d. manufacturing the upper end plate through integral molding; e. installing the weld seam protection device on the pipe body; f. Connect the straight capillaries firmly. The invention hides the welding seam in the welding seam protection device, protects the welding seam, avoids the phenomenon of welding seam cracking, improves the safety performance of the refrigeration process, and can fix the gap between two adjacent straight tube capillary tubes connected as a whole. The connection makes the two straight tube capillary tubes form a whole, which increases the stability of the straight tube capillary tube during the refrigeration process.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and in particular relates to a straight capillary used for refrigeration fittings and a processing method thereof. Background technique [0002] Refrigeration equipment is a device that combines a refrigerator with a facility that uses cold energy. Refrigeration devices are designed and constructed to effectively use cold energy to refrigerate food or other items; to conduct product performance tests and scientific research tests at low temperatures; to achieve certain cooling processes in industrial production, or to perform air conditioning. When items are cooled or frozen, a certain amount of heat will be released, and the enclosure structure of the refrigeration device will also transfer a certain amount of heat when it is in use. Therefore, in order to maintain the low temperature conditions in the refrigeration device, a refrigerator must be installed to continuously remove the heat,...
