中亞天然氣項(xiàng)目首批

氣液聯(lián)動(dòng)全焊接球閥交付

良固閥門(mén)持續(xù)拓展全球能源工程市場(chǎng)

近日，良固閥門(mén)集團(tuán)出口中亞天然氣長(zhǎng)輸管線(xiàn)項(xiàng)目的氣液聯(lián)動(dòng)全焊接球閥完成生產(chǎn)并進(jìn)入分批發(fā)運(yùn)階段。

該批產(chǎn)品用于天然氣干線(xiàn)截?cái)嗯c站場(chǎng)控制系統(tǒng)，首批口徑覆蓋DN1000–DN1200

(40″-48″)， Class 600壓力等級(jí)設(shè)計(jì)，服務(wù)于區(qū)域能源輸送主干網(wǎng)絡(luò)中的關(guān)鍵節(jié)點(diǎn)。

該項(xiàng)目所對(duì)應(yīng)的管線(xiàn)系統(tǒng)運(yùn)行環(huán)境復(fù)雜，線(xiàn)路需跨越荒漠及戈壁地帶，長(zhǎng)期處于高壓輸送與顯著晝夜溫差變化的工況條件下，對(duì)閥門(mén)的結(jié)構(gòu)穩(wěn)定性、密封可靠性及長(zhǎng)期運(yùn)行一致性提出了持續(xù)性要求。

Recently, the first batch of fully welded ball valves for a Central Asia natural gas transmission project has completed manufacturing and entered staged shipment.

The valves will be used in main gas transmission pipelines and station control systems, covering sizes from DN1000 to DN1200 (40″-48″), designed for Class 600 pressure rating, serving critical nodes of regional energy transmission networks. The project serves a key regional energy transportation network.

The pipeline system operates in harsh environments, crossing desert and plateau regions, with long-distance transmission, high pressure, and large temperature differences between day and night. This places strict requirements on valve structural stability, sealing reliability, and long-term operational consistency.

面向長(zhǎng)輸干線(xiàn)的結(jié)構(gòu)設(shè)計(jì)與工程適配Engineering Design for Long-Distance Transmission

產(chǎn)品的整體式全焊接閥體結(jié)構(gòu)，適用于地下直埋及長(zhǎng)周期免維護(hù)運(yùn)行工況。

相較于分體式結(jié)構(gòu)，全焊接設(shè)計(jì)在長(zhǎng)輸管線(xiàn)應(yīng)用中可減少潛在連接界面，從結(jié)構(gòu)層面提升整體密封連續(xù)性與外部環(huán)境適應(yīng)能力，更符合天然氣主干線(xiàn)對(duì)長(zhǎng)期安全運(yùn)行的工程要求。

針對(duì)高壓輸送系統(tǒng)，閥門(mén)在球體加工、閥座密封結(jié)構(gòu)及配合面精度控制方面進(jìn)行了系統(tǒng)化工藝管理，以保證在Class 600壓力工況下的穩(wěn)定密封表現(xiàn)與動(dòng)作一致性。

These fully welded ball valves adopt an integral welded body design, suitable for direct buried pipelines and long-term maintenance-free operation.

Compared with split-body structures, the fully welded design reduces potential leakage paths and improves structural integrity, making it more suitable for natural gas trunk line applications requiring long service life and high safety levels.

For high-pressure service conditions, the valve design includes optimized ball machining, sealing structure, and precision control of mating surfaces to ensure stable sealing performance under Class 600 pressure rating conditions.

執(zhí)行系統(tǒng)與遠(yuǎn)程控制能力集成Actuation and Control System Integration

本批產(chǎn)品配套氣液聯(lián)動(dòng)執(zhí)行機(jī)構(gòu)，用于長(zhǎng)距離管線(xiàn)系統(tǒng)的遠(yuǎn)程啟閉與聯(lián)鎖控制需求。

該類(lèi)執(zhí)行系統(tǒng)通常應(yīng)用于站場(chǎng)集中控制或無(wú)人值守管段，通過(guò)氣液驅(qū)動(dòng)方式實(shí)現(xiàn)大扭矩輸出與穩(wěn)定動(dòng)作控制，滿(mǎn)足天然氣長(zhǎng)輸系統(tǒng)在緊急切斷與遠(yuǎn)程調(diào)度場(chǎng)景下的響應(yīng)要求。

閥門(mén)本體與執(zhí)行機(jī)構(gòu)在出廠(chǎng)前完成整閥聯(lián)調(diào)與動(dòng)作測(cè)試，確保機(jī)械結(jié)構(gòu)與控制系統(tǒng)在統(tǒng)一工況條件下的匹配性與可靠性。

Each valve is equipped with a pneumatic-hydraulic actuator system, designed for remote operation and interlocking control in long-distance pipeline networks.

This system is widely used in unmanned or centralized control stations, providing high torque output and stable actuation performance for emergency shut-off and remote pipeline management.

Each valve undergoes full assembly testing and actuator calibration before shipment to ensure mechanical and control system compatibility under real operating conditions.
