The assembly of valve fittings is the last stage in the manufacturing process. Regarding its assembly, it is necessary to combine the various parts and components of the valve and make it a product according to the premise of delineating the skills. The complete machine is the most basic unit of valve assembly, and several parts make up the valve parts of the valve, such as the valve cover and the flap part.
The assembly quality of the valve fitting has an important influence on the performance of the product. In other words, even if the design is accurate and the parts are qualified, if the assembly is improper, the valves will not reach the required requirements, or even produce leakage. Therefore, it is necessary to use an appropriate assembly process to ensure the final product quality of the valve.
At present, in the process of assembling valve components, there are mainly three methods used, namely: complete exchange method, repair method and matching method. Regardless of which method is used, the valve fittings must be reviewed prior to assembly to prevent unburred and uncleaned parts from entering the final assembly. During the assembly process, the parts must be handled gently to avoid bumps and scratches. http://www.dmgcastings.com/
