So, through set up refrigeration piece 15 on the AB dispensing valve, make the utility model discloses a dispensing valve has the refrigeration function to can delay the solidification rate that the AB glued, improve the point and glue the quality. Moreover, the cold conducting piece 14 is preferably made of copper; the use of copper as the cold conductive member 14 has an advantage of good heat conduction effect.
Further, the cooling conducting part 14 has a cylindrical part 141, the upper end of the cylindrical part 141 extends outward to form a first extending part 142, the lower end of the cylindrical part 141 extends outward to form a second extending part 143, and an installation ring is formed between the first extending part 142 and the second extending part 143; the refrigerating piece 15 and the heat dissipation device 16 are both arranged on the installation ring position.
Usually, the first extending portion 142 is provided with a first connecting hole penetrating up and down, and the valve body 10 is provided with a second connecting hole matching with the first connecting hole;
when the connecting device is installed, the first connecting hole corresponds to the second connecting hole and is connected through the connecting piece. The connector may be a bolt.
In practice, the cooling element 15 may be a semiconductor cooling element 15, which has a cold end surface and a hot end surface, and the cold end surface is connected to the cold conducting element 14, and the hot end surface is connected to the heat sink 16.
