在現(xiàn)代工業(yè)體系中，閥門被譽(yù)為“工業(yè)血脈的樞紐”，其性能直接關(guān)系到整個(gè)系統(tǒng)的安全與穩(wěn)定。作為中國閥門制造領(lǐng)域的代表企業(yè)，良工閥門集團(tuán)憑借其深厚的歷史底蘊(yùn)、出眾的技術(shù)實(shí)力以及廣泛的市場應(yīng)用，成為了出眾裝備制造業(yè)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(chuàng)建的“良工機(jī)器廠”，歷經(jīng)數(shù)十載歲月洗禮，于1992年正式組建集團(tuán)。企業(yè)不僅擁有溫州總部、麗水等多個(gè)現(xiàn)代化生產(chǎn)基地，更在1984年成為我國閥門行業(yè)首批獲得美國石油協(xié)會(huì)API認(rèn)證的企業(yè)。從1960年為大型化肥企業(yè)開發(fā)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(jí)閥門，再到2019年通過“華龍一號(hào)”核電機(jī)組技術(shù)評(píng)審，良工閥門始終與國家重大工程同頻共振，展現(xiàn)了強(qiáng)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(chǎn)品與技術(shù)方面，良工閥門的產(chǎn)品線出彩為豐富，涵蓋了閘閥、截止閥、球閥、蝶閥、止回閥及電站閥等。其產(chǎn)品能夠適應(yīng)出彩其苛刻的工況，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℃的出彩寬區(qū)間。在制造工藝上，良工閥門引進(jìn)了德國技術(shù)圖紙與設(shè)計(jì)軟件，采用CAD設(shè)計(jì)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，確保了閥門在出彩端環(huán)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(yè)智能化的發(fā)展，良工閥門也在不斷進(jìn)行技術(shù)創(chuàng)新與專利研發(fā)。例如，企業(yè)近期申請的“核一級(jí)穩(wěn)壓器氣動(dòng)卸壓閥”專利，通過大小閥瓣組合設(shè)計(jì)大大減小了操作力，提升了抗震性能；而“具有自清理刮屑結(jié)構(gòu)的防堵閥門”專利，則有效解決了介質(zhì)雜質(zhì)導(dǎo)致的閥門堵塞問題。這些創(chuàng)新不僅提升了產(chǎn)品的使用壽命，更滿足了新能源、環(huán)保等新興領(lǐng)域的嚴(yán)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(chǎn)品已廣泛應(yīng)用于能源電力、石油化工、城市建設(shè)等關(guān)鍵領(lǐng)域。作為中國石油、中國化工集團(tuán)的供應(yīng)商，以及核電、軍工領(lǐng)域的核心配套企業(yè)，良工閥門憑借AAA級(jí)銀行信用等級(jí)和“重合同守信用單位”等榮譽(yù)，確立了國產(chǎn)中出眾閥門的市場地位。在價(jià)格上，良工閥門以優(yōu)于進(jìn)口品牌的性價(jià)比和媲美國際一流的技術(shù)標(biāo)準(zhǔn)，為我國工業(yè)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.
