在現代工業體系中，閥門被譽為“工業血脈的樞紐”，其性能直接關系到整個系統的安全與穩定。作為中國閥門制造領域的標桿企業，良工閥門集團憑借其深厚的歷史底蘊、卓越的技術實力以及廣泛的市場應用，成為了高端裝備制造業的一張亮麗名片。

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.

良工閥門的歷史可以追溯至1946年創建的“良工機器廠”，歷經數十載歲月洗禮，于1992年正式組建集團。企業不僅擁有溫州總部、麗水等多個現代化生產基地，更在1984年成為我國閥門行業首批獲得美國石油協會API認證的企業。從1960年為大型化肥企業開發全系列高壓化肥閥，到1972年為我國第一座核電站秦山核電站研制核級閥門，再到2019年通過“華龍一號”核電機組技術評審，良工閥門始終與國家重大工程同頻共振，展現了強大的“大國重器”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".

在核心產品與技術方面，良工閥門的產品線極為豐富，涵蓋了閘閥、截止閥、球閥、蝶閥、止回閥及電站閥等。其產品能夠適應極其苛刻的工況，公稱通徑覆蓋6mm至3200mm，壓力范圍從1.0MPa至42MPa，工作溫度更是跨越了-196℃至1200℃的極寬區間。在制造工藝上，良工閥門引進了德國技術圖紙與設計軟件，采用CAD設計及有限元分析，并配備X射線探傷、光譜分析等精密檢測手段，確保了閥門在極端環境下的密封性、耐腐蝕性與耐高低溫性能。

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.

隨著工業智能化的發展，良工閥門也在不斷進行技術創新與專利研發。例如，企業近期申請的“核一級穩壓器氣動卸壓閥”專利，通過大小閥瓣組合設計大大減小了操作力，提升了抗震性能；而“具有自清理刮屑結構的防堵閥門”專利，則有效解決了介質雜質導致的閥門堵塞問題。這些創新不僅提升了產品的使用壽命，更滿足了新能源、環保等新興領域的嚴苛需求。

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，良工閥門的產品已廣泛應用于能源電力、石油化工、城市建設等關鍵領域。作為中國石油、中國化工集團的供應商，以及核電、軍工領域的核心配套企業，良工閥門憑借AAA級銀行信用等級和“重合同守信用單位”等榮譽，確立了國產中高端閥門的市場地位。在價格上，良工閥門以優于進口品牌的性價比和媲美國際一流的技術標準，為我國工業流體控制提供了安全、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.
