Problems solved by technology

[0002] The bellows used for air conditioners are generally stainless steel pipes. At present, the stainless steel bellows used for air conditioners on the market adopt the leak-proof technology of collars and gaskets, and are compressed with nuts. The sealing ring is compressed by nuts, so there are defects such as cracks and leakage in stainless steel pipes

Embodiment Construction

[0010] As shown in the figure, the present invention is mainly composed of a bellows 5. The two ends of the bellows 5 are provided with ribs 4, and the ribs 4 are provided with a fixed sealing ring 3 injection-molded at one time. The fixed sealing ring 3 is also provided with a joint nut 2, the joint nut 2 is screwed to the joint 1, and the convex rib 4, the one-time injection-molded fixed sealing ring 3 and the joint 1 are compressed through the joint nut 2 to achieve a tight seal. connection effect.

[0011] The manufacturing process of the present invention is: because the ribs 4 are provided near the two ports of the corrugated pipe 5, the ribs 4 that are located near the two ports of the corrugated pipe 5 are also formed at one time when the corrugated pipe 5 is manufactured. The ribs 4 on the bellows 5 are partially put into the injection molding machine, and the outer periphery of the ribs 4 is poured into a fixed sealing ring 3 .

[0012] The invention is suitable for...

Abstract

The invention discloses a connecting tube of the end of a water system of a central air conditioner and a manufacture process thereof. The connecting tube consists of a stainless steel corrugated tube. Both ends of the corrugated tube are provided with convex ribs; a fixed seal ring of once injection moulding is respectively arranged on the convex ribs; the fixed seal ring of once injection moulding is also provided with a joint nut; the joint nut is rotatably connected with a joint; and the convex ribs, the fixed seal ring of once injection moulding and the joint are compressed by the joint nut, thereby achieving the effect of seal connection. The invention has the manufacture process: due to the fact that the convex ribs are arranged near both end openings of the corrugated tube, the convex ribs arranged near both end openings are also molded at one time while the corrugated tube is manufactured; the convex ribs on the corrugated tube are put in a plastic injection machine; and the fixed seal ring is cast on the peripheries of the convex ribs. The invention is suitable for connecting the ends of water-system air conditioners.

Description

technical field [0001] The invention relates to a terminal connecting pipe of a central air-conditioning water system and a manufacturing process thereof. Background technique [0002] The bellows used for air conditioners are generally stainless steel pipes. At present, the stainless steel bellows used for air conditioners on the market adopt the leak-proof technology of collars and gaskets, and are compressed with nuts. The sealing ring is compressed by nuts, so there are defects such as cracks and leakage in stainless steel pipes. Contents of the invention [0003] The object of the present invention is to provide a central air-conditioning water system terminal connection pipe with good compressive strength and water leakage prevention and its manufacturing process for the above-mentioned defects of the air-conditioning stainless steel pipe. [0004] In order to achieve the above object, the present invention mainly adopts the following technical solutions to complete...
