Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of ship equipment, and specifically refers to a ship ballast system pipeline valve body assembly. BACKGROUND

[0002] In global trade, bulk carriers are the main carriers of bulk commodity transportation, and their safe and efficient operation is crucial. The ballast system is a key component of bulk carriers, and plays a decisive role in the stability, draft adjustment and navigation safety of the ship. In the construction of the traditional bulk carrier ballast system, the arrangement of the pipeline valve is always the focus of the industry.

[0003] For a long time, there have been two main ways to arrange the pipeline valves of the traditional bulk carrier ballast system. One is to arrange the pipeline valves in the pipe, which can protect the valves to some extent, but the design and construction of the pipe will increase the complexity and cost of the ship structure, and the space of the pipe is limited, making it difficult to maintain and repair later. For ships without pipe design, the valve can only be designed as a whole immersion type. However, the immersion type design has many serious defects. First of all, the drive device of the valve is immersed in seawater for a long time, and seawater contains a large amount of salt, microorganisms and complex chemicals, which will cause strong corrosion to the metal parts of the drive device. Corrosion not only damages the surface material of the drive device, but also affects the normal operation of the internal precision mechanical structure and electronic components, greatly increasing the probability of damage to the drive device, causing frequent failures, and thus affecting the normal operation of the ballast system, and even threatening the safety of ship navigation. According to relevant statistics, the failure of the drive device due to corrosion accounts for 30% - 40% of the total number of failures in the ballast system with immersion type valves, and the maintenance cost is high, the maintenance period is long, and the operation efficiency of the ship is seriously affected. Secondly, the cost of manufacturing the immersion type valve is relatively high. Due to the need to withstand high pressure, corrosion and complex water flow of seawater, the immersion type valve is made of special alloy or composite material to prolong its service life, which greatly increases the cost of raw materials. At the same time, its manufacturing process is more complex, requiring higher precision and quality control standards, further increasing the manufacturing cost. Moreover, in the aspect of maintenance and repair, since the valve is in the state of underwater immersion, maintenance personnel need to use professional diving equipment or special underwater tools to operate, which not only increases the difficulty and time cost of maintenance, but also puts high demands on the skills and safety of maintenance personnel. Once the valve fails, a large amount of manpower, material resources and financial resources are needed to repair, and the reliability after repair is difficult to guarantee. With the development of the shipping industry, the control of ship operation cost and safety requirements are increasingly high, and the disadvantages of the traditional ballast system valve arrangement method are becoming more and more prominent.
