What is the marine sea valve device?

All partners who know about the ship will know the marine sea valve. On most ships, there are many cast marine valves. The positions of these sea valves are different, and the sizes are also very different. And in most warships, the sea valve is generally regarded as an important device. First, it is used as a cooling device. When the ship needs to run, whether it is a steam turbine or a diesel engine, it needs to burn a lot of fuel and release a lot of heat. In order to avoid damage to the ship, a complete cooling system must be equipped.

Take the steam turbine as an example. Although most of the heat generated by the boiler is used for work, the temperature of the steam after use is still very high. And the boiler water is recycled. On the one hand, it is impossible for the ship to carry too much water because of traveling at sea; on the other hand, the temperature of boiler water may cause damage to the ship. So the cooling system becomes very important.

The general cooling system will be equipped with a large-scale condenser, which needs to continuously add low-temperature seawater, so that the steam can be cooled down and recycled as boiler water. So how do we need to get seawater? Since we need more seawater, it is obviously impossible to transport it manually.

In addition, war boats are generally large in size, and it is unlikely to be equipped with special personnel to condense. The risk of this is also very large, and it is easy to cause the ship to sink. If the whole condensing system cannot be effectively circulated, the power system of the ship will also be affected. So the sea valve came into being. It is generally necessary to determine the specific position of the sea valve according to the position of the condenser. Some sea valves are mainly installed at higher places, while others are installed at lower places.

In fact, the main function of the sea valve is to condense. But can also be used for some other applications. For example, after the warship is damaged, it needs to enter the dock for repair. At this time, it needs to use the sea valve. It can be used as a spare valve to make repair easier and convenient.

There are many sea valves for general ships, especially for large war boats, which can even reach dozens or even hundreds. This design is mainly to meet the needs of ships.
