| titleOfInvention | A kind of manufacturing process of heat exchanger quick joint with good sealing performance |
| abstract | The invention discloses a manufacturing process of a quick joint for a heat exchanger with good sealing performance. In the manufacturing process, one end of two threaded sleeves is first welded to the two ends of a bent pipe by a spot welding machine, and then a sealing ring is welded. It is inserted into the gap between the threaded sleeve and the two sides of the elbow, and then the shape of the elbow is changed into a bell mouth shape through a flaring machine, and the O-ring is squeezed between the elbow and the inner threaded joint to form a seal. Then put the bushing into the bell mouth, press the surface of the straight copper pipe to form a ring groove, put it into the male threaded joint, and then put in the circlip, and finally combine the copper pipe straight pipe kit with the U-shaped elbow kit. The invention has a reasonable process, the O-shaped sealing ring increases the sealing between the threaded cap and the elbow, the bushing increases the sealing between the copper tube and the copper tube, and also increases the sealing between the threaded cap and the socket nut. The tightness is good, and the manufacturing process is simple and fast, so as to provide a heat exchanger quick joint with good tightness. |
