Description
Technical Field
The utility model relates to a control device, in particular to a marine quick-closing valve control device.
Background
In order to ensure the safety of the ship, the specification requires that the oil supply valve of the oil tank is closed when the ship is in fire, so that the fire condition is prevented from further greatly influencing the ship body. In case of a cabin fire, the crew cannot access the cabin and shut off the oil valve for safety reasons. In order to ensure timely shut-off of the oil valve, in general the vessel will be designed with a remote valve closing system, i.e. a personnel remote control in a safe position will close the hatch rapidly. The engine room and the operation position of the traditional ship are arranged at the stern, and a crew can quickly close the oil supply valve at the engine room inlet in time. However, for special ships, such as semi-submersible, the cabin is arranged at the stern, the crew resides at the bow, and if the traditional manual closing mode is adopted, the quick-closing valve control box and the gas cylinder are required to be arranged at the bow of the ship body. In general, since the length of the ship is about 200 meters, if the ship is designed according to the conventional design concept and method, the following defects exist:
1. because the valve is pneumatically controlled, the valve cannot be closed quickly because of the long distance of the ship.
2. Because the distance of the pipelines to be laid is longer, the gas consumption in the pipelines is increased, and the very huge gas cylinder capacity support is needed.
3. The valve control pipe generally adopts 10 x 1 pipeline, and overlength is arranged and is once slightly damaged, will lead to the valve unable to close, and the security risk is high.
4. The large volume gas cylinders and longer piping arrangement will increase material consumption and construction costs.
There is a need for a marine quick-closing valve control device that can support the quick-closing valve control box and the gas cylinder to be disposed in a safe area nearest to the nacelle, thereby reducing the layout cost while achieving quick-closing of the oil tank valve.

The traditional manual oil valve closing mode needs to arrange a quick-closing valve control box and a gas cylinder at the bow of the ship. The operator needs to go to the quick-closing valve control box as soon as possible and manually control the ball valve and cause the quick-closing valve control box to close the gas supply to the oil tank valve located at the stern of the ship. Since the length of the vessel 30 is typically around 200 meters, the length of the air supply piping for transporting compressed air will be too long. On the one hand, because the transmission distance of compressed air is longer, the valve can not be closed rapidly, and the ship can not be protected timely, and simultaneously the gas consumption in the pipeline is increased, and very huge gas cylinder capacity support is needed. On the other hand, the gas supply pipeline serving as the valve control pipe generally adopts a pipeline of 10 x 1, and once the valve cannot be closed due to slight damage caused by overlong arrangement, the safety risk is high.

The three-way air supply pipe is provided with two pipelines at one side of the air distributor, so that only one pipeline is closed in maintenance work for the three-way air supply pipe, and the working of the device is not influenced. The volume of the gas cylinder is preferably 180L, the working pressure of the gas cylinder is preferably 3MPa, the working medium is preferably compressed air, and the output air pressure of the gas cylinder after decompression by the decompression valve is 0.7MPa.
