閥門起源于中國，它早在公元兩千多年前就出現了。我國古代就在輸水 管道上使用了竹管和木塞閥，以后又在灌溉渠道上使用水閘，在冶煉用的風箱上使用板式止回閥，隨著 鍋爐的使用，1681年又出現了杠桿重錘式安全閥。在井鹽開采方面使用竹管和板式止回閥提取鹽水隨著 冶煉技術和水力機械的發展，在歐洲出現了銅制和鉛制旋塞閥。

　　Valves originated in China and appeared over two thousand years ago. In ancient China, bamboo pipes and wooden plug valves were used in water pipelines. Later, water gates were used in irrigation channels, and plate check valves were used in wind boxes for smelting. With the use of boilers, lever heavy hammer safety valves appeared in 1681. With the development of smelting technology and hydraulic machinery, copper and lead plug valves have emerged in Europe for extracting saltwater using bamboo pipes and plate check valves in well salt mining.

　　公元前 1800年，古埃及人為了防止尼羅河泛濫而修建大規模水利時，也曾采用過類似的木制旋塞 來控制水流的分配。這些都是閥門的雛形。工業用閥門的大量應用，是從瓦特發明蒸汽機以后才開始的 。二十世紀初出現了鑄鋼、鑄鐵、鍛鋼和鍛焊結構閥門。

　　In 1800 BC, when the ancient Egyptians built large-scale water conservancy projects to prevent flooding of the Nile River, they also used similar wooden plugs to control the distribution of water flow. These are the prototypes of valves. The widespread application of industrial valves began after Watt invented the steam engine. At the beginning of the 20th century, cast steel, cast iron, forged steel, and forged welded structural valves emerged.

　　隨后歐洲因為冶煉技術和水利機械的發展，對閥門的要求也逐漸提高，于是發明出了銅制和鋁制的旋塞閥，閥門才進入金屬制。1769年瓦特發明了蒸汽機使閥門正式進入了機械工業領域，蒸汽機上大量采用旋塞閥、安全閥、止回閥和氣動蝶閥。18世紀到19世紀，蒸汽機在采礦業、冶煉、紡織、機械制造等行業的迅速推廣，對閥門數量以及質量日益增加，于是出現了滑閥。相繼出現的帶螺紋閥桿的截止閥和帶梯形螺紋閥桿的楔式閘閥，是閥門發展中的一次重大突破，這兩類閥門的出現不僅滿足了當時各個行業對閥門壓力及溫度不斷提高的要求，而且初步滿足了對流量調節的要求。

　　Subsequently, due to the development of smelting technology and water conservancy machinery, Europe's requirements for valves gradually increased, so copper and aluminum plug valves were invented, and valves entered the metal industry. In 1769, Watt invented the steam engine, which officially introduced valves into the mechanical industry. Plug valves, safety valves, check valves, and pneumatic butterfly valves were widely used in steam engines. In the 18th and 19th centuries, the rapid promotion of steam engines in industries such as mining, smelting, textiles, and machinery manufacturing led to an increasing number and quality of valves, resulting in the emergence of slide valves. The successive emergence of globe valves with threaded valve stems and wedge gate valves with trapezoidal threaded valve stems was a major breakthrough in valve development. The emergence of these two types of valves not only met the increasing requirements for valve pressure and temperature in various industries at that time, but also initially met the requirements for flow regulation.

　　此后，電力、石油、化工、造船行業的興起，各種高中壓的閥門得到了迅速發展。世界大戰后，由于各種特殊材料，包括聚合材料、潤滑材料、不銹鋼和鈷基硬質合金的發展，古老的旋塞閥和蝶閥獲得了新的應用，根據旋塞閥演變的球閥和隔膜閥得到迅速發展。截止閥、閘閥和其他閥門品種增加，質量提高。使得閥門制造業逐漸成為機械工業的一個重要部門。

　　Subsequently, with the rise of the power, petroleum, chemical, and shipbuilding industries, various high and medium pressure valves have rapidly developed. After World War II, due to the development of various special materials, including polymer materials, lubricating materials, stainless steel, and cobalt based hard alloys, ancient plug valves and butterfly valves gained new applications, and ball valves and diaphragm valves evolved rapidly based on plug valves. The variety and quality of globe valves, gate valves, and other valves have increased. The valve manufacturing industry has gradually become an important sector of the machinery industry.
