在閥門行業(yè)，“良工”是一個有分量的名字。它的分量不來自廣告投放，而來自一個簡單的事實：中國第一座自行設計建造的核電站——秦山核電站，用的是良工閥門。

In the valve industry, "Lianggong" is a weighty name. Its weight does not come from advertising placement, but from a simple fact: China's first self-designed and built nuclear power plant, the Qinshan Nuclear Power Plant, uses Lianggong valves.

1946年建廠，1952年造出國內(nèi)首批高壓鑄鋼閥門。 良工機器廠創(chuàng)建于1946年的上海，1952年成功制造2英寸1500磅級高壓鑄鋼閥門，開創(chuàng)了我國自制高壓鑄鋼閥門的歷史。此后數(shù)十年，良工閥門的發(fā)展軌跡幾乎與中國工業(yè)化的關鍵節(jié)點重合：1960年為吳涇化肥廠設計制造全系列高壓氮肥閥，為大慶油田制造采油樹高壓閥門；1974年起為秦山核電站研制核二、三級閘閥、截止閥等產(chǎn)品。

The factory was established in 1946 and the first batch of high-pressure cast steel valves in China were produced in 1952. Lianggong Machinery Factory was founded in Shanghai in 1946. In 1952, it successfully manufactured 2-inch 1500 pound high-pressure cast steel valves, creating a history of self-made high-pressure cast steel valves in China. In the following decades, the development trajectory of Lianggong Valve almost coincided with the key nodes of China's industrialization: in 1960, it designed and manufactured a full series of high-pressure nitrogen fertilizer valves for Wujing Fertilizer Plant, and manufactured high-pressure valves for oil trees in Daqing Oilfield; Since 1974, we have been developing nuclear second and third stage gate valves, globe valves, and other products for the Qinshan Nuclear Power Plant.

“工”字牌是良工產(chǎn)品的核心標識。 1999年，“工”字牌商標獲評上海市著名商標。市場上打著“良工”旗號的公司不少，但真正傳承了良工技術體系和制造標準的，是持有“工”字牌商標的上海良工閥門廠有限公司。對于采購方來說，認準“工”字牌，是避免買到“同名不同質(zhì)”產(chǎn)品的關鍵。

The "Gong" sign is the core identifier of Lianggong products. In 1999, the "Gong" trademark was awarded as a famous trademark in Shanghai. There are many companies in the market that claim to be "Lianggong", but the one that truly inherits Lianggong's technical system and manufacturing standards is Shanghai Lianggong Valve Factory Co., Ltd., which holds the "Gong" trademark. For the purchaser, identifying the "work" sign is the key to avoiding buying products with the same name but different quality.

良工的產(chǎn)品線覆蓋出彩廣。 從核電、軍工到石化、電力，從閘閥、截止閥到球閥、蝶閥，規(guī)格從DN15到DN600，壓力等級從1.0MPa到70.0MPa。材質(zhì)涵蓋不銹鋼、鑄鋼、鑄鐵、鍛鋼等，驅(qū)動方式支持手動、電動、氣動、齒輪傳動。這種“全品類覆蓋”的能力，使其能夠滿足從民用建筑到國家核心工程的不同層級需求。

Lianggong's product line covers a wide range. From nuclear power and military industry to petrochemicals and electricity, from gate valves and globe valves to ball valves and butterfly valves, specifications range from DN15 to DN600, and pressure levels range from 1.0MPa to 70.0MPa. The materials include stainless steel, cast steel, cast iron, forged steel, etc. The driving mode supports manual, electric, pneumatic, and gear transmission. The ability to cover all categories enables it to meet different levels of needs from civil construction to national key projects.

值得關注的是，良工閥門近年來持續(xù)參與國家標準制定。 2024年，公司參與制定了5項閥門產(chǎn)品國家標準。這意味著，良工的技術經(jīng)驗正在從“企業(yè)標準”上升為“行業(yè)標準”，這對用戶而言是產(chǎn)品質(zhì)量穩(wěn)定性的又一重保障。

It is worth noting that Lianggong Valve has been continuously involved in the formulation of national standards in recent years. In 2024, the company participated in the development of 5 national standards for valve products. This means that Lianggong's technical experience is rising from the "enterprise standard" to the "industry standard", which is another guarantee for the stability of product quality for users.
