Seven characteristics of stainless steel spheres
Stainless steel balls are usually steel balls produced by stainless steel casting technology. Currently, common materials for stainless steel balls include 201, 302, 304, 316, 316L, 420, and 440C.
1. Convenient maintenance of Chengdu plastic extruder bearings. The ball valve structure is simple, and the stainless steel ball seal ring is generally movable, making it very easy to disassemble and replace the ball valve.
2. Close and reliable bearings for Chengdu plastic extruders. Currently, the sealing surface of ball valves in the bearing section of Chengdu plastic extruders is generally made of plastic with good sealing properties. Stainless steel spheres have also been widely used in ultrafiltration devices.
3. The stainless steel sphere is easy to operate in practice, with fast opening and closing. It only needs to be rotated 90 ° from opening to closing, which is conducive to remote control.
When opened or fully closed, the sealing surfaces of the ball and valve block are isolated from the medium. When the material is rooted in the bearing of the Chengdu plastic extruder shaft, the stainless steel ball of the bearing of the Chengdu plastic extruder is not easy to cause corrosion of the valve sealing surface.
5. The application field of Chengdu plastic extruder bearings is wide, with pipe diameters ranging from a few millimeters to several meters, and can be used with high vacuum pumps and no working pressure.
6. The liquid has low frictional resistance, and its resistance coefficient is the same as that of pipes of the same size.
7. The stainless steel sphere has a simple structure, small size, and light weight.
