Detailed Description
The present invention will be further described with reference to the accompanying drawings.
The utility model discloses a divide liquid tee bend for central air conditioning, including straight tube 1 and return bend 2, the material of straight tube 1 and return bend 2 all is copper, and straight tube 1 welds with return bend 2, and the welding mode of straight tube 1 and return bend 2 is brazed, and the solder contains silver-colored welding rod.
As shown in fig. 2, 5 and 6, a skirt joint 101 is formed at an end of the straight pipe 1, the skirt joint 101 is formed by expanding a lower end pipe orifice of the straight pipe 1, the skirt joint 101 is composed of a left fin 1011, a front wall 1012, a right fin 1013 and a rear wall 1014, and the left fin 1011 and the right fin 1013 are mainly drawn outward as seen in fig. 6. As shown in fig. 4 and 7, a neck interface 201 is formed on the tube wall of the elbow 2, the neck interface 201 is composed of a left shoulder 2011, a front face 2012, a right shoulder 2013 and a rear face 2014, and the neck interface 201 is processed by drilling a circular hole on the tube wall of the elbow 2, and then drawing the circular hole outward to form the shape shown in fig. 7. As shown in fig. 1 to 3, the skirt joint 101 is fitted over the neck joint 201, the left raised portion 1011 abuts against the left shoulder 2011, the front wall portion 1012 abuts against the front face portion 2012, the right raised portion 1013 abuts against the right shoulder 2013, and the rear wall portion 1014 abuts against the rear face portion 2014. The brazed weld is along the lower edge of the skirt joint 101. Through comparing with the prior art shown in fig. 8, the utility model discloses a straight tube 1 is avoided to the structure inserts return bend 2 to can reduce the influence to the refrigerant flow, moreover the utility model discloses a skirt joint 101 is great with the area of contact of protruding neck interface 201, and welding back structural strength is higher, avoids receiving exogenic action and making the welding seam fracture when the actual installation is used, can see from fig. 1, because skirt joint 101 cover is outside protruding neck interface 201, so when brazing, be heated molten solder can not flow in return bend 2, thereby more can guarantee the utility model discloses an excellent in use, because the solder can not flow in return bend 2, so the waste of solder reduces by a wide margin, can reduce cost.
