Basic Functions of Marine Valves

Marine valves, as crucial components in underwater pipelines and ship systems, undertake the key tasks of controlling fluid medium pressure, flow rate, and flow direction. These valves find wide application in marine oil and gas engineering, ship navigation systems, and deep-sea submersibles. Below are the basic functions of marine valves and their English translation.

1. Control of Fluid Medium Flow

The most basic function of marine valves is to connect or disconnect the flow of media within pipelines. They achieve this through the movement of closure members (such as gate plates, valve discs, etc.) to control fluid media. This function is vital for maintaining the normal operation of pipeline systems.

2. Adjustment of Pressure and Flow Rate

Marine valves also possess the ability to adjust the pressure and flow rate of fluid media. For instance, by modifying the valve's opening degree, the fluid pressure within the pipeline can be precisely controlled, ensuring stable system operation. Simultaneously, valves can regulate the media's flow rate according to practical needs, fulfilling various process requirements.

3. Prevention of Reverse Flow

In certain circumstances, to prevent reverse flow of fluid media, marine valves are designed with one-way flow capability. These valves permit media flow only in a specific direction; if the fluid flows in reverse, the valve automatically closes, thereby protecting the system from damage.

4. Safety Protection

Marine valves also play a significant role in safety protection in ships and marine engineering. For example, in emergency situations, by rapidly closing the valve, the flow path of hazardous media can be cut off, preventing accidents from escalating. Additionally, valves can automatically open or close under specific conditions, ensuring the safe operation of the system.

In summary, as essential equipment in marine engineering and ship systems, marine valves perform basic functions such as controlling fluid medium flow, adjusting pressure and flow rate, preventing reverse flow, and providing safety protection. The fulfillment of these functions offers robust support for the safe and stable operation of marine engineering and ships.
