Technical Field

[0001] The utility model relates to the technical field of hot forged copper, in particular to a four-way hot forged copper joint. Background Art

[0002] At present, some air conditioners on the market use aluminum alloy four-way valves, but aluminum alloy valves are not resistant to high pressure and low temperature. Although they are affordable and low in price, they are prone to valve body bursting and are extremely easy to oxidize, causing leakage. Some valve bodies will crack and the structural strength is insufficient. In addition, the traditional installation method of the valve body inside the air conditioner is basically to match the shape of the valve body with the corresponding internal structural rib limit design, which has a complex structure, is unstable and unreliable, and is not easy to install.

DETAILED DESCRIPTION

[0022] The following is further described in detail through specific implementation methods:

[0023] like Figure 1-3 As shown, this embodiment shows a four-way hot-forged copper joint 100, including a horizontally arranged main tube 110, a push rod connecting tube 120 arranged on the left side of the main tube 110, a plug connecting tube 130 arranged on the right side of the main tube 110, a liquid outlet connecting tube 140 arranged at the top of the main tube 110, and a liquid inlet connecting tube 150 arranged at the bottom of the main tube 110.

[0024] Among them, the four-way hot-forged copper joint 100 of this embodiment is integrally formed and connected; the push rod connecting tube 120, the main tube 110 and the plug connecting tube 130 are connected in a straight line. Specifically, in this embodiment, the center lines of the three tubes of the push rod connecting tube 120, the main tube 110 and the plug connecting tube 130 are on the same straight line. Further, the center lines of the five tubes of the main tube 110, the push rod connecting tube 120, the plug connecting tube 130, the liquid outlet connecting tube 140 and the liquid inlet connecting tube 150 are on the same plane.

[0025] In this embodiment, the angle between the liquid outlet connecting pipe 140 and the main pipe 110 is 30 degrees. A first reinforcing rib 160 is provided at the acute angle between the two, and a second reinforcing rib 170 is provided at the obtuse angle between the two.

[0026] In this embodiment, the liquid inlet connecting pipe 150 and the main pipe 110 are arranged perpendicular to each other, and a third reinforcing rib 180 and a fourth reinforcing rib 190 are respectively arranged at the angles on the left and right sides of the liquid inlet connecting pipe 150 and the main pipe 110. Figure 2 As shown, the liquid inlet connecting pipe 150 and the main pipe 110 are arranged perpendicular to each other so as to match the internal connection structure.

[0027] Further description, in some embodiments, such as Figure 1-3 As shown, the first reinforcing rib 160 , the third reinforcing rib 180 and the fourth reinforcing rib 190 are arranged in a triangular plate shape as a whole.

[0028] Further description, in some embodiments, such as Figure 1-3 As shown, the second reinforcing rib 170 is arranged in a long strip shape as a whole. To further explain in detail, reinforcing ribs are arranged between each tube body to achieve the purpose of enhancing the overall structural strength.

[0029] Further description, in some embodiments, such as Figure 1-3 As shown, the main body tube 110, the liquid inlet connecting tube 150 and the liquid outlet connecting tube 140 are respectively provided with protruding installation limit blocks 200 on both sides of the front and back; the three installation limit blocks 200 on the same side are not in the same straight line. Figure 3 As shown, the installation limit block 200 includes a circular boss base 210 and a limit convex circle 220 fixedly arranged on the circular boss base 210. Figure 3As shown, installation limit blocks 200 are respectively provided on the front and rear sides of the main tube 110, the liquid inlet connecting tube 150 and the liquid outlet connecting tube 140. When the four-way hot-forged copper joint 100 is actually installed, the four-way hot-forged copper joint 100 is reliably clamped in the shell by matching the installation limit blocks 200. Furthermore, the three installation limit blocks 200 on the same side are not in the same straight line, which further limits the degree of freedom in all directions on the same plane, thereby improving the installation reliability.
