Butterfly valve is a frequently used valve in industrial water system. It has become a common valve for pipelines because of its small size and high cost performance. The main products of butterfly valves are wafer soft-sealed butterfly valves and flanged butterfly valves. Although there are fewer types of butterfly valves than gate valves, there are also many differences to adapt to different wor...

Gravity casting refers to the process of injecting molten metal into a mold under the action of the earth's gravity, also known as casting. The generalized gravity casting includes sand casting, metal casting, investment casting, lost foam casting, mud casting, etc.; the narrow gravity casting specifically refers to metal casting. The molten metal is generally poured into the gate manually, and th...

At present, more than 80% of copper in the world is made by fire method, and it is mainly used to process copper sulfide ore. Pyrometallurgy is to melt copper ore (or calcine, agglomerate, etc.) and flux at high temperature, or directly smelt into blister copper, or first smelt into matte (melt mainly composed of copper, iron and sulfur) Then smelt into blister copper. Except for some operations (...

The valve body is one of the main parts of the valve; there are different mechanical manufacturing methods according to the pressure level. For example: casting, forging, etc. The definition of "valve" is a device used to control the direction, pressure, and flow of fluid in a fluid system. A valve is a device that allows the medium (liquid, gas, powder) in the piping and equipment to flow or stop...

1. Structure difference: CNC machining center is controlled by at least three axes, while CNC lathe is controlled by two axes. 2. Tool difference: CNC machining center has a tool magazine, and CNC lathe uses a tool post. There are more classifications of CNC machining center tool holders than CNC lathe tool holders, such as disc type, hat type, chain type, flying saucer type, simultaneous movement...
