阀门起源于中国，它早在公元两千多年前就出现了。我国古代就在输水 管道上使用了竹管和木塞阀，以后又在灌溉渠道上使用水闸，在冶炼用的风箱上使用板式止回阀，随着 锅炉的使用，1681年又出现了杠杆重锤式安全阀。在井盐开采方面使用竹管和板式止回阀提取盐水随着 冶炼技术和水力机械的发展，在欧洲出现了铜制和铅制旋塞阀。

　　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，是从瓦特发明蒸汽机以后才开始的 。二十世纪初出现了铸钢、铸铁、锻钢和锻焊结构阀门。

　　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.

　　随后欧洲因为冶炼技术和水利机械的发展，对阀门的要求也逐渐提高，于是发明出了铜制和铝制的旋塞阀，阀门才进入金属制。1769年瓦特发明了蒸汽机使阀门正式进入了机械工业领域，蒸汽机上大量采用旋塞阀、安全阀、止回阀和气动蝶阀。18世纪到19世纪，蒸汽机在采矿业、冶炼、纺织、机械制造等行业的迅速推广，对阀门数量以及质量日益增加，于是出现了滑阀。相继出现的带螺纹阀杆的截止阀和带梯形螺纹阀杆的楔式闸阀，是阀门发展中的一次重大突破，这两类阀门的出现不仅满足了当时各个行业对阀门压力及温度不断提高的要求，而且初步满足了对流量调节的要求。

　　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，电力、石油、化工、造船行业的兴起，各种高中压的阀门得到了迅速发展。世界大战后，由于各种特殊材料，包括聚合材料、润滑材料、不锈钢和钴基硬质合金的发展，古老的旋塞阀和蝶阀获得了新的应用，根据旋塞阀演变的球阀和隔膜阀得到迅速发展。截止阀、闸阀和其他阀门品种增加，质量提高。使得阀门制造业逐渐成为机械工业的一个重要部门。

　　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.
