简述阀门的历史

阀门的历史
阀门是随着流体管路的产生而产生的。人类使用阀门已经有近4000年的历史了。中国古代从盐井中吸卤水制盐时，就曾在竹制管路中使用
过木塞阀。公元前1800年，古埃及人为了防止尼罗河泛滥而修建大规模水利时，也曾采用过类似的木制旋塞来控制水流的分配。这些都
是阀门的雏形。工业用阀门的大量应用，是从万特发明蒸汽机以后才开始的。二十世纪初出现了铸铁，铸钢，锻钢，不锈钢，铬钼钢，黄
铜等各种材质的阀门。应用干各个行业，各种工况。国内ZUI早引进国外阀门生产技术的公司不多，后引进国外生产技术，使得国内阀门生
产技术的突破，质量的提高，寿命的加长。

History of Valves

The valve is produced with the flow line. Humans have been using valves for nearly 4,000 years. In ancient China, when brine was siphoned from salt Wells to make salt, it was used in bamboo pipes

Pass the plug valve. Similar wooden cocks were used by the ancient Egyptians in 1800 BC to control the distribution of water when they built a massive water conservancy to keep the Nile from flooding. All of these

It's the prototype of the valve. A large number of industrial valve applications, from the invention of the steam engine Vante only began. In the early 20th century, cast iron, cast steel, forged steel, stainless steel, chrome-molybdenum steel, yellow

Copper and other materials of the valve. Applied to various industries, various working conditions. The earliest introduction of foreign valve production technology companies are not many, after the introduction of foreign production technology, so that the domestic valve

The breakthrough of production technology, the improvement of quality, the extension of life.
