Description

This invention relates to shipbuilding.

From the main auth. 629118 a device is known for leveling an emergency roll of a vessel, comprising tanks located on opposite sides and connected by a flow channel, and a shut-off valve with an actuator, pipes and non-return valves. The shut-off valve actuator is in the form of a piston and a cylinder, with the piston mounted in the cylinder and rigidly connected to the shut-off valve, and the piston cylinder cavity communicates with the onboard tanks through pipes in which the main non-return valves are located.

However, in such a device, after the emergency situation is eliminated, when water from tanks is removed, due to the one-way action of non-return valves, water remains from the piston-cylinder area of the cylinder, which is not. Allows the shut-off valve to return to its original position. In order to remove the diver from the half piston cavity, it is necessary to dismantle the locking device.

The purpose of the invention is to improve the performance of the device.

This is achieved by the fact that the device is equipped with an additional non-return valve and an additional pipe connecting the sub-piston chamber of the cylinder with the overflow channel;

10 valve installed in optional. The diameter of the bore section of the additional non-return valve is made not more than one-tenth of the diameter of the flow-through section of the main non-return valve.

FIG. 1 shows the proposed device, a general view; on. 2 - the same, longitudinal section; on fig.Z -

2C the same, longitudinal section on non-return valves.

The device for leveling the emergency roll of the vessel contains on-board tanks 1 and 2 connected by a channel 25, in which the locking device 4 is located, having a housing 5 and a valve 6, which through a rod 7 is connected to a drive made in the form of a piston 8 at

thirty

cylinder 9. Cylinder 9 is fixed to housing 5 by means of cover 10, with piston cavity 11 communicating with tanks 1, and 2 using pipes 12 and 13 in which main non-return valves 14 and 15 are mounted. In addition, cavity 11 communicates with the channel 3 through an additional non-return valve 16, the flow area of which is not more than one-tenth of the flow section of the valve 15, and an additional nipple 17.

The device works as follows.

When a ship’s side is damaged, outboard water enters, for example, tank 1 and through channel 3 into device 4. Valve b closes channel 3 and water when a certain level is reached in tank 1 through pipe 13 through valve 15 enters cavity 11. In connection so that the flow area of the valve 16 is significantly less than the flow area of the valve 15, an overpressure is created in the cavity 11. As a result, the hygiene 8 rises, opens the channel 3, and the water from the tank 1 enters the tank 2. After the damage has been removed and removed, from tanks 1 and 2 on By the action of the weight of the valve 6, water from the cavity 11 flows through the valve 16 and the nozzle 17 into the channel 3, while the piston 8 is lowered and the valve 6 closes the channel 3. The device is returned to its original position.

The use of the present invention will simplify the operation of the locking device, since it eliminates its disassembly after an emergency.
