閘閥的啟閉件是閘板，閘板的運動方向與流體方向相垂直。閥門依靠閥桿帶動閘板做升降運動，從而實現(xiàn)管道的開啟與關(guān)閉。當(dāng)閘板完全升起時，閥體內(nèi)部介質(zhì)通道呈直線貫通，介質(zhì)幾乎可以無阻礙地流過。這種直通式流道設(shè)計賦予閘閥非常顯著的優(yōu)勢——流動阻力小，流體壓力損失出彩低。在需要保持管道系統(tǒng)壓力穩(wěn)定的場景中，這一特性尤為珍貴。

The opening and closing component of a gate valve is the gate, and the direction of movement of the gate is perpendicular to the direction of the fluid. The valve relies on the stem to drive the gate to move up and down, thereby achieving the opening and closing of the pipeline. When the gate is fully raised, the internal medium channel of the valve body is connected in a straight line, and the medium can flow almost unobstructed. This straight through flow channel design gives gate valves the most significant advantage - low flow resistance and extremely low fluid pressure loss. This feature is particularly valuable in scenarios where it is necessary to maintain stable pressure in pipeline systems.

良工閘閥在產(chǎn)品結(jié)構(gòu)上形成了豐富的技術(shù)路線。按閘板形式可分為楔式閘閥和平行式閘閥兩大類。楔式閘閥的閘板呈楔形，關(guān)閉時依靠楔緊力實現(xiàn)密封，結(jié)構(gòu)簡單、密封可靠。平行式雙閘板閘閥則采用兩片閘板中間帶有撐開機(jī)構(gòu)的設(shè)計，閘板向閥座的壓緊力由介質(zhì)壓力自動控制。良工核二級平行式雙閘板閘閥采用了全行程準(zhǔn)確導(dǎo)向設(shè)計和中腔雙重密封結(jié)構(gòu)，閘板全行程運動均有準(zhǔn)確導(dǎo)向，確保啟閉動作的平穩(wěn)可靠。

Lianggong gate valve has formed a rich technical route in product structure. According to the form of the gate, it can be divided into two categories: wedge gate valves and parallel gate valves. The gate of the wedge gate valve is wedge-shaped, and when closed, it relies on the clamping force to achieve sealing. The structure is simple and the sealing is reliable. The parallel double gate valve adopts a design with a spreading mechanism in the middle of two gate plates, and the clamping force of the gate plate to the valve seat is automatically controlled by the medium pressure. The Lianggong Nuclear Second Stage Parallel Double Gate Valve adopts a full stroke precise guidance design and a double sealing structure in the middle chamber. The full stroke movement of the gate is precisely guided, ensuring smooth and reliable opening and closing actions.

在工業(yè)管道的萬千閥門中，閘閥是非常為基礎(chǔ)也非常為常見的品類之一。它如同管道系統(tǒng)的“開關(guān)”，承擔(dān)著切斷和接通介質(zhì)流通的核心任務(wù)。良工閥門作為擁有七十余年閥門制造經(jīng)驗的老牌企業(yè)，在閘閥領(lǐng)域積累了深厚的技術(shù)底蘊，產(chǎn)品覆蓋通用工業(yè)、核電、石油化工等多個出眾領(lǐng)域

Among the thousands of valves in industrial pipelines, gate valves are one of the most basic and common categories. It is like a "switch" in a pipeline system, responsible for the core task of cutting off and connecting the flow of media. As a well-established enterprise with over 70 years of valve manufacturing experience, Lianggong Valve has accumulated profound technical expertise in the field of gate valves, with products covering multiple high-end fields such as general industry, nuclear power, and petrochemicals
