What is the manufacturing process of all welded ball valve?

Release date: August 23, 2019

All welded ball valve What's the manufacturing process like? Understanding all welded ball valve can bring us better benefits.

Forging method: This is a traditional processing method. If we want a complete set of smelting equipment, we need a large workshop and a lot of workers. The investment is relatively large, the production process is also relatively complex, which pollutes the environment. The technical level of workers directly affects the quality of products. The machining allowance is large and the waste is large. If casting defects are found in the processing process, the cost of products will increase and the quality can not be guaranteed.

Casting method: 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 and less chip free processing technique, which belongs to the new branch of pressure processing. It integrates the process characteristics of forging, extrusion, rolling and rolling, and has high material utilization rate, which can save a lot of processing time, and the material strength after spinning can be doubled.

The components of all welded ball valve are introduced as follows: the surface of all welded ball valve is a curved surface, which is called spherical surface. The ball is similar to a circle and has a central center. The circle cut by the plane of the spherical center is called the big circle, and the circle that is not cut through the cross section of the spherical center is called the small circle.

On the sphere, the shortest connecting line length between two points is the length of a inferior arc between the two points of the big circle passing through the two points. The arc length of the sphere is called the spherical distance of the two points.
