閥門的歷史
閥門是隨著流體管路的產(chǎn)生而產(chǎn)生的。人類使用閥門已經(jīng)有近4000年的歷史了。中國(guó)古代從鹽井中吸鹵水制鹽時(shí)，就曾在竹制管路中使用
過(guò)木塞閥。公元前1800年，古埃及人為了防止尼羅河泛濫而修建大規(guī)模水利時(shí)，也曾采用過(guò)類似的木制旋塞來(lái)控制水流的分配。這些都
是閥門的雛形。工業(yè)用閥門的大量應(yīng)用，是從萬(wàn)特發(fā)明蒸汽機(jī)以后才開(kāi)始的。二十世紀(jì)初出現(xiàn)了鑄鐵，鑄鋼，鍛鋼，不銹鋼，鉻鉬鋼，黃
銅等各種材質(zhì)的閥門。應(yīng)用干各個(gè)行業(yè)，各種工況。國(guó)內(nèi)ZUI早引進(jìn)國(guó)外閥門生產(chǎn)技術(shù)的公司不多，后引進(jìn)國(guó)外生產(chǎn)技術(shù)，使得國(guó)內(nèi)閥門生
產(chǎn)技術(shù)的突破，質(zhì)量的提高，壽命的加長(zhǎng)。

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.
