良固铝青铜联动式
三通球阀组
应用于船舶海水过滤系统大型船舶发动机的持续运行，离不开稳定的海水冷却系统。
而在这一系统中，过滤器的连续运行直接关系到整套系统的安全与稳定。
船舶海水过滤系统通常采用双路设计：一路运行，一路备用；或一路维护，另一路持续工作。
那么，两路过滤系统如何实现不停机、不中断、可靠切换？
良固阀门近期交付的 C95800 铝青铜联动式双联三通球阀组，正是为这一需求制造交付。
它专为海水介质、双路冗余和连续运行工况打造，确保双路系统能安全、可靠地切换。
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.
这款产品，“特殊”在哪里？
结构上，这款产品采用上下双三通球阀联动设计。
两只三通球阀通过联动机构同步动作，在不改变系统既定流向的前提下，实现两路过滤通道之间的快速切换。
核心作用不是分流，而是换向：
1-双阀联动，同步切换
上下阀体联动控制，避免多阀独立操作带来的不同步问题，使切换动作更直接、更清晰。
2-贴合双路过滤器工况
适用于一路工作、一路备用的系统设计，也适用于过滤器在线维护时的快速切换需求。
3-提高系统运行确定性
在船舶连续运行场景中，越是关键的切换节点，越需要减少人为不确定性。联动式阀组，本质上就是在降低系统切换风险。
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.
如果说结构解决的是切换问题，那么材质解决的就是寿命与稳定性问题。
这款阀组阀体采用C95800 铝青铜材质。
在船舶及海工领域，这是一类成熟且具有代表性的耐海水材料，尤其适用于高盐、高湿、高腐蚀环境下的海水介质工况。
其主要优势包括：
-优异的抗海水腐蚀能力；
-良好的抗氯离子腐蚀性能；
-较强的抗冲刷能力；
-良好的抗气蚀性能。
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.
