Manufacturing process of fully welded ball valve
Forging method: This is a traditional processing method. It requires a complete set of smelting equipment, a relatively large factory building and a lot of workers. The investment is relatively large, and the production process is relatively complex. It pollutes the environment. The technical level of the workers directly affects the quality of the product. The machining allowance of the blank is large and the waste is large. Casting defects are found during the processing, which increases the product cost and the quality cannot be guaranteed.
Casting method: The round steel is cut, heated and forged into a spherical solid blank, and then welded into a spherical blank for processing. The material utilization rate is very high and the material utilization rate is high.
Spinning method: Metal spinning method is an advanced low-chip, chip-free processing technique. It is a new branch of pressure processing. It combines the characteristics of forging, extrusion, rolling and rolling. It has a relatively high material utilization rate and can save money. With a lot of processing time, the material strength after spinning can be doubled.
Fully welded ball valves can be buried directly underground, eliminating the need to build tall valve wells and reducing project costs. At the same time, they can avoid personal injury when operating the valves. They can operate reliably for a long time and can be used in various harsh environments, such as petrochemical, In power stations, steel industries, etc., when using fully welded ball valves, some details must be paid attention to, which can extend the service life of welded ball valves.
