Anode polarization and coloration treatment method of aluminum alloy extinguisher valve body

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. Compared with the conventional aluminum alloy press forging, the aluminum alloy multiple-ram forging adopted by the invention reduces the production steps, and is capable of greatly enhancing the material utilization ratio, reducing the equipment investment, lowering the energy consumption and greatly enhancing the production efficiency.

Description

[0001] The patent application of the present invention is a divisional application with the application number: 201210440807.8. The filing date of the original application is: November 7, 2012. The name of the invention is: an aluminum alloy fire extinguisher valve body and its manufacturing method. technical field [0002] The invention relates to a material and a manufacturing method of a valve body of a dry powder fire extinguisher. Background technique [0003] Fire extinguishers are an important fire-fighting tool. Whether in public buildings, companies, or households, some fire extinguisher devices will be equipped in case of emergency. However, there are some problems in the current use process. During a certain storage period If the metal of the valve body is corroded, the sealing performance will be gradually lost, which directly affects the shelf life of the fire extinguisher, and also affects the need for emergency fire extinguishing at any time. The valve bodies ...

AI Technical Summary

Problems solved by technology

[0003] Fire extinguishers are an important fire-fighting tool. No matter in public buildings, companies, or homes, some fire extinguisher devices will be equipped in case of emergency. However, there are some problems in the current use process. In a certain storage period If the metal of the valve body is corroded, the sealing performance will be gradually lost, which directly affects the shelf life of the fire extinguisher, and also affects the need for emergency fire extinguishing at any time.

The valve bodies of fire extinguishers on the market are made of copper and iron, which are not only high in cost, but also easily corroded, which brings a lot of inconvenience to users. Compared with aluminum alloy valve bodies, they have low cost, light weight and simple production process. , easy to machine, and can meet the performance requirements of fire extinguishers
