Copper bar production capacity in China is mainly distributed in coastal areas As the world's largest producer and consumer of copper processing products, the production and consumption of Copper processing products in China are mainly concentrated in east China and South China.
Three-way valve body has three, one in and two out, (left in, right and under) and the common valve is different from the bottom has an outlet, when the internal valve in different positions, the outlet is different, such as the core in the lower, left and right communication, such as the spool in the upper, the right exit blocked, left and under the mouth.
The earliest production mode in the field of valves, because the casting type does not have enough pressure, the valve produced by this process is easy to produce sand holes, leading to product leakage and a series of problems.
Choose according to the installation structure.The installation structure of pipeline system includes pipe thread, flange, clamp sleeve, welding, hose, etc.Therefore, the installation structure of the valve must be consistent with the installation structure of the pipeline, and the specifications should be in line with the size.
The valve connected by pipe thread is connected with the pipe thread of the pipe end. The internal thread can be a cylindrical pipe thread or a tapered pipe thread, and the external thread must be a tapered pipe thread
