良固鋁青銅聯動式

三通球閥組

應用于船舶海水過濾系統

大型船舶發動機的持續運行，離不開穩定的海水冷卻系統。

而在這一系統中，過濾器的連續運行直接關系到整套系統的安全與穩定。

船舶海水過濾系統通常采用雙路設計：一路運行，一路備用；或一路維護，另一路持續工作。

那么，兩路過濾系統如何實現不停機、不中斷、可靠切換？

良固閥門近期交付的 C95800 鋁青銅聯動式雙聯三通球閥組，正是為這一需求制造交付。

它專為海水介質、雙路冗余和連續運行工況打造，確保雙路系統能安全、可靠地切換。

The continuous operation of large ship engines relies on a stable seawater cooling system.

Within this system, the uninterrupted operation of filters directly affects the safety and stability of the entire system.

Ship seawater filtration systems typically use a dual-line configuration: one line in operation while the other is on standby, or one line under maintenance while the other continues working.

So how can the two filtration lines switch reliably without shutdown or interruption?

The C95800 Aluminum Bronze Actuated Dual Three-Way Ball Valve Assembly recently delivered by LIANGGU Valve is designed precisely for this requirement.

It is engineered for seawater service, dual-line redundancy, and continuous operation, ensuring safe and reliable switching between the two lines.

這款產品，“特殊”在哪里？

結構上，這款產品采用上下雙三通球閥聯動設計。

兩只三通球閥通過聯動機構同步動作，在不改變系統既定流向的前提下，實現兩路過濾通道之間的快速切換。

核心作用不是分流，而是換向：

1-雙閥聯動，同步切換

上下閥體聯動控制，避免多閥獨立操作帶來的不同步問題，使切換動作更直接、更清晰。

2-貼合雙路過濾器工況

適用于一路工作、一路備用的系統設計，也適用于過濾器在線維護時的快速切換需求。

3-提高系統運行確定性

在船舶連續運行場景中，越是關鍵的切換節點，越需要減少人為不確定性。聯動式閥組，本質上就是在降低系統切換風險。

Structurally, this product features an actuated dual three-way ball valve design.

The two three-way ball valves operate synchronously through a linkage mechanism, enabling rapid switching between the two filtration lines without altering the system’s predefined flow path.

Its core function is not flow distribution, but directional change:

1-Synchronized dual-valve operation

The upper and lower valve bodies are linked for coordinated control, avoiding desynchronization issues caused by independent valve operation, and making the switching action more direct and precise.

2-Optimized for dual-line filtration systems

Suitable for systems with one line in operation and one on standby, as well as for scenarios requiring rapid switching during online filter maintenance.

3-Enhanced operational certainty

In continuous shipboard operations, the more critical the switching point, the greater the need to minimize human-induced uncertainty. The actuated valve assembly effectively reduces switching risks within the system.

如果說結構解決的是切換問題，那么材質解決的就是壽命與穩定性問題。

這款閥組閥體采用C95800 鋁青銅材質。

在船舶及海工領域，這是一類成熟且具有代表性的耐海水材料，尤其適用于高鹽、高濕、高腐蝕環境下的海水介質工況。

其主要優勢包括：

-優異的抗海水腐蝕能力；

-良好的抗氯離子腐蝕性能；

-較強的抗沖刷能力；

-良好的抗氣蝕性能。

If the design addresses the switching function, the material ensures durability and operational stability.

The valve bodies of this assembly are made of C95800 Aluminum Bronze.

In the shipbuilding and offshore industry, this is a well-established and representative material for seawater service, particularly suited for high-salinity, high-humidity, and highly corrosive seawater conditions.

Its key advantages include:

-Excellent resistance to seawater corrosion；

-Strong resistance to chloride-induced corrosion；

-High erosion resistance；

-Good cavitation resistance.
