Valves are essential parts of any piping system used to control the flow and pressure of contents, whether that is oil, gas, liquid, or vapors.We are talkimg about the ball valve here. A ball valve is a quarter-turn rotational motion valve that used a ball-shaped disk to control a flow. If the valve is opened, the holes in the ball stay in line with the body inlet allowing contents to pass. Ball v...

A Ball Valve is a quarter turn valve which can be opened or closed by applying pressure on the hollow and pivoting ball inserted into void opening. It is usually used as a switch that can control and direct the flow of fluids (including air, water, gas, oil etc.). When the hole in the ball is aligned to the flow, it is open and closed when it is perpendicular. Automatic brass ball machine carries ...

Traditional faucets are made of brass. The process flow is as follows: copper ingot→dissolving→casting→cleaning after casting→casting inspection→machining→tolerance inspection→grinding→surface inspection→plating→plating inspection→assembly→pressure test→ Finished product inspection → packaging → delivery. There are a total of 16 processes, and each process is strictly controlled to ensure quality....

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 (...
