在现代工业体系中，阀门被誉为“工业血脉的枢纽”，其性能直接关系到整个系统的安全与稳定。作为中国阀门制造领域的标杆企业，良工阀门集团凭借其深厚的历史底蕴、卓越的技术实力以及广泛的市场应用，成为了高端装备制造业的一张亮丽名片。

In modern industrial systems, valves are known as the "hub of industrial bloodline", and their performance directly affects the safety and stability of the entire system. As a benchmark enterprise in the field of valve manufacturing in China, Lianggong Valve Group has become a shining business card in the high-end equipment manufacturing industry with its profound historical background, outstanding technical strength, and extensive market applications.

良工阀门的历史可以追溯至1946年创建的“良工机器厂”，历经数十载岁月洗礼，于1992年正式组建集团。企业不仅拥有温州总部、丽水等多个现代化生产基地，更在1984年成为我国阀门行业首批获得美国石油协会API认证的企业。从1960年为大型化肥企业开发全系列高压化肥阀，到1972年为我国第一座核电站秦山核电站研制核级阀门，再到2019年通过“华龙一号”核电机组技术评审，良工阀门始终与国家重大工程同频共振，展现了强大的“大国重器”制造能力。

The history of Lianggong Valve can be traced back to the establishment of "Lianggong Machinery Factory" in 1946. After decades of baptism, the group was officially formed in 1992. The enterprise not only has multiple modern production bases such as Wenzhou headquarters and Lishui, but also became one of the first enterprises in China's valve industry to obtain API certification from the American Petroleum Institute in 1984. From developing a full range of high-pressure fertilizer valves for large fertilizer enterprises in 1960, to developing nuclear grade valves for China's first nuclear power plant, Qinshan Nuclear Power Plant, in 1972, and passing the technical review of the "Hualong One" nuclear power unit in 2019, Lianggong Valve has always resonated with major national projects, demonstrating its strong manufacturing capabilities as a "major national heavy equipment".

在核心产品与技术方面，良工阀门的产品线极为丰富，涵盖了闸阀、截止阀、球阀、蝶阀、止回阀及电站阀等。其产品能够适应极其苛刻的工况，公称通径覆盖6mm至3200mm，压力范围从1.0MPa至42MPa，工作温度更是跨越了-196℃至1200℃的极宽区间。在制造工艺上，良工阀门引进了德国技术图纸与设计软件，采用CAD设计及有限元分析，并配备X射线探伤、光谱分析等精密检测手段，确保了阀门在极端环境下的密封性、耐腐蚀性与耐高低温性能。

In terms of core products and technology, Lianggong Valve has an extremely rich product line, covering gate valves, globe valves, ball valves, butterfly valves, check valves, and power station valves. Its products can adapt to extremely harsh working conditions, with nominal diameters ranging from 6mm to 3200mm, pressure ranges from 1.0MPa to 42MPa, and working temperatures spanning a wide range from -196 ℃ to 1200 ℃. In terms of manufacturing process, Lianggong Valve has introduced German technical drawings and design software, using CAD design and finite element analysis, and equipped with precision testing methods such as X-ray inspection and spectral analysis to ensure the sealing, corrosion resistance, and high and low temperature resistance of the valve in extreme environments.

随着工业智能化的发展，良工阀门也在不断进行技术创新与专利研发。例如，企业近期申请的“核一级稳压器气动卸压阀”专利，通过大小阀瓣组合设计大大减小了操作力，提升了抗震性能；而“具有自清理刮屑结构的防堵阀门”专利，则有效解决了介质杂质导致的阀门堵塞问题。这些创新不仅提升了产品的使用寿命，更满足了新能源、环保等新兴领域的严苛需求。

With the development of industrial intelligence, Lianggong Valve is also constantly undergoing technological innovation and patent research and development. For example, the recent application for the patent of "Pneumatic Relief Valve for Nuclear Level One Voltage Regulator" by the enterprise greatly reduces the operating force and improves the seismic performance through the combination design of large and small valve discs; The patent for "anti blocking valve with self-cleaning and scraping structure" effectively solves the problem of valve blockage caused by impurities in the medium. These innovations not only enhance the lifespan of products, but also meet the stringent demands of emerging fields such as new energy and environmental protection.

目前，良工阀门的产品已广泛应用于能源电力、石油化工、城市建设等关键领域。作为中国石油、中国化工集团的供应商，以及核电、军工领域的核心配套企业，良工阀门凭借AAA级银行信用等级和“重合同守信用单位”等荣誉，确立了国产中高端阀门的市场地位。在价格上，良工阀门以优于进口品牌的性价比和媲美国际一流的技术标准，为我国工业流体控制提供了安全、可靠的保障。

At present, Lianggong Valve's products have been widely used in key fields such as energy and power, petrochemicals, and urban construction. As a supplier of China National Petroleum Corporation and China National Chemical Corporation, as well as a core supporting enterprise in the fields of nuclear power and military industry, Lianggong Valve has established its market position in the domestic mid to high end valve industry with its AAA bank credit rating and honors such as "Contract abiding and Creditworthy Unit". In terms of price, Lianggong Valve provides a safe and reliable guarantee for industrial fluid control in China with better cost-effectiveness than imported brands and comparable international first-class technical standards.
