Title:
SEALING METHOD FOR REFRIGERATION PIPELINE, AND REFRIGERATION PIPELINE
Document Type and Number:
WIPO Patent Application WO/2023/040291
Kind Code:
A1
Abstract:
A sealing method for a refrigeration pipeline, and a refrigeration pipeline. The sealing method for a refrigeration pipeline comprises: S602: covering a butt joint of a first pipeline (110) with a sealing device (130), wherein the sealing device (130) at least has a sealant storage cavity (131), and the sealant storage cavity (131) is used for covering the butt joint of the first pipeline (110); S604: injecting a sealant into the sealing device (130) through an opening (133) of the sealant storage cavity (131); S606: moving the sealing device (130) in a direction away from the butt joint to expose the butt joint; S608: sleeving a second pipeline (120) on the butt joint; and S610: moving the sealing device (130) in the direction of the butt joint, so that the sealing device (130) covers the butt joint between the second pipeline (120) and the first pipeline (110), and injecting the sealant into the sealing device (130) through the opening (133) of the sealant storage cavity (131) again. The sealant fills the space between the first pipeline (110) and the second pipeline (120), and the sealant fills the space between the sealing device (130) and the first pipeline (110) and between the sealing device (130) and the second pipeline (120); therefore, double sealing protection of the butt joint between the first pipeline (110) and the second pipeline (120) is achieved, and the sealing effect is good. The refrigeration pipeline is sealed by means of the sealing device (130) and the sealant, thereby solving the technical problems of the current flame-brazing sealing being unsafe, etc.
