Abstract
The invention discloses an anode polarization and coloration treatment method of an aluminum alloy extinguisher valve body. The aluminum alloy extinguisher valve body is composed of a valve body, a press-type valve core hole, a nozzle, a grip fixing hole, a nozzle internal thread, a seal ring, a grip fixing bracket, an internal thread and an external thread. The valve body is made of a 6061 aluminum alloy. The 6061 aluminum alloy comprises the following chemical components: 0.8-1.2% of Mg, 0.4-0.8% of Si, 0.15-0.4% of Cu, 0.7% of Fe, 0.15% of Mn, 0.25% of Zn, 0.04-0.35% of Cr, 0.15% of Ti and the balance of aluminum. Compared with the copper valve body, the aluminum alloy extinguisher valve body has lower cost; the surface-polarized oxidation film can well avoid the corrosion of the extinguishing agent, thereby greatly prolonging the service life of the extinguisher; and the aluminum alloy extinguisher valve body has the advantages of simple production technique, light weight, long storage life and high reliability.
