Referring to fig. 1-2, in the ship tank apparatus and the maintenance method thereof according to the present invention, the tank 1 may be a fresh water tank for providing daily water, a ballast system for adjusting ballast conditions, a fuel tank for storing fuel, or a sewage tank for storing sewage, and the general space of the tank 1 is limited, so that the tank 1 is generally fixed at the top of the tank, and the tank 1 is installed at a position close to the wall at the top for reasonable space distribution of the tank, thereby saving a certain space. Generally, the water inlet pipe for supplying water to the tank 1 is to feed water from the side wall or the top of the tank 1, but because the structure of the ship body is complex, the installation space of some tanks 1 is limited, and it is difficult to realize the water feeding mode, and water can only be fed from the bottom of the tank 1.

According to the ship cabin cabinet device and the maintenance method, a hole is formed in the bottom of the cabin cabinet 1, the stop check valve 4 is installed at the hole, and the stop check valve 4 is communicated with the first section of the injection pipe 2. The advantage of installation like this lies in that collocation remote control valve 5 mutually supports with ending check valve 4, and at the water supply in-process, can reduce the water hammer effect according to ending check valve 4 and remote control valve 5's cooperation relation, reduces the impact force of liquid to pumping 6 and first section injection pipe 2 and second section injection pipe 3, has improved pumping 6 and first section injection pipe 2 and second section injection pipe 3's life to a certain extent.

First section injection pipe 2 is located the below of cabin 1, communicate through ending check valve 4 between first section injection pipe 2 and the cabin 1, communicate with second section injection pipe 3 and perpendicular to ground, be equipped with remote control valve 5 in first section injection pipe 2 and the 3 intercommunication departments of second section injection pipe, (the position of remote control valve 5 can be selected according to the length of first section injection pipe 2, if first section injection pipe 2 length is very short, can directly install remote control valve 5 and lean on ground position) first section injection pipe 2 and the 3 intercommunication departments of second section injection pipe are the arc, pump 6 is fixed subaerial, communicate through second section injection pipe 3 and pump 6.

In the water supply process, the remote control valve 5, the stop check valve 4 and the pump 6 are opened in sequence, the drain valve 7 is closed until the liquid capacity of the cabin is sufficient, at the moment, the stop check valve 4, the pump 6 and the remote control valve 5 are closed in sequence, the drain valve 7 is opened, and redundant liquid is discharged from the pipeline; or the pump 6, the remote control valve 5 and the stop check valve 4 are opened in sequence, the drain valve 7 is closed until the liquid capacity of the cabin is sufficient, at the moment, the stop check valve 4, the pump 6 and the remote control valve 5 are closed in sequence, the drain valve 7 is opened, and the redundant liquid is discharged out of the pipeline.

In the maintenance process, when a pipeline between the stop check valve 4 and the remote control valve 5 is broken, the pumping 6 and the stop check valve 4 are closed in sequence, then the relief valve 7 is opened, the liquid in the first section of the injection pipe 2 flows out of the second section of the injection pipe 3, then the liquid is discharged out of the pipeline through the relief valve 7, when the liquid is completely discharged, the pipeline inspection and maintenance are started, and when the maintenance is finished, normal water supply is started; when the pipeline between the remote control valve 5 and the pump 6 is broken, the pump 6, the stop check valve 4 and the remote control valve 5 are closed in sequence, then the relief valve 7 is opened, liquid in the second section of the injection pipe 3 is discharged, the inspection and the maintenance are started, and the normal operation is carried out when the maintenance is finished; when the pump 6 breaks down, the stop check valve 4 and the remote control valve 5 are closed, then the discharge valve 7 is opened, the liquid in the second section of the injection pipe 3 is discharged through the discharge valve 7, then the maintenance is carried out, and the normal work is started after the maintenance is finished.

Referring to fig. 1, tank 1 is a ballast tank, water tank, fuel tank, or sewage tank. The maintenance device which cuts off liquid flowing out from the source can be suitable for various cabins 1, such as a common fresh water cabin 1, a sewage cabin for storing sewage and a fuel oil cabin for storing fuel oil.

Referring to fig. 1, the first section of the injection pipe 2 is perpendicular to the bottom surface of the tank 1, and the distance between the remote control valve 5 and the stop check valve 4 is greater than the distance between the remote control valve 5 and the water inlet 24 of the first section of the injection pipe. Because most cabin cabinets 1 of boats and ships set up the top in the boats and ships cabin, mainly because the cabin space of placing cabin cabinet 1 is more limited, first section filling pipe 2 one end is perpendicular with cabin cabinet 1 ground, and stop check valve 4 sets up on the bulkhead of cabin cabinet 1, can directly cut off liquid on the source, remote control valve 5 sets up the position that is close to cabin ground at first section filling pipe 2 water inlet, can ensure the impact force of the water of reducing to first section filling pipe 2 of certain degree when supplying water like this, thereby the life of pipeline has been improved.

Referring to fig. 1, the tank 1 is a ballast tank, the pump 6 is a ballast pump, the ballast tank is disposed at the bottom of the hull of the ship, and the ballast pump is located outside the hull and is in communication with seawater. The ballast tank is positioned at the bottom of the ship and is connected with seawater, a fresh water tank, a fuel oil tank, a sewage tank and the like of the ship are arranged at the upper layer of the ballast tank, the ballast tank mainly extracts seawater and discharges seawater through a pump 6 and a discharge valve 7 to provide balance force for the ship, and the pump 6 is selected to be correspondingly replaced according to different tanks 1.

Referring to fig. 1, the remote control valve 5 is disposed at the water inlet 24 of the first section of the injection pipe, and the pipeline distance between the stop check valve 4 and the remote control valve 5 is greater than the pipeline distance between the remote control valve 5 and the pump 6. Because the cabin space for placing the cabin cabinet 1 is smaller, when the pipeline is assembled, the lengths of the first section injection pipe 2 and the second section injection pipe 3 can be matched according to the specific space of the cabin, and under the normal condition, the length of the first section injection pipe 2 is often longer than that of the second section injection pipe 3.

Referring to fig. 1, the first section of injection pipe 2 includes a first pipe and a second pipe, the water outlets of the first pipe and the second pipe are connected to the tank 1, and the water inlets of the first pipe and the second pipe are connected to the water outlet of the second section of injection pipe 3. The size and the number of the injection pipes of the first section of injection pipe 2 and the second section of injection pipe 3 can be determined according to the specific size of the cabin 1, and the larger the capacity of the cabin 1 is, the larger the injection pipes should be, the corresponding size and number should be selected, so that certain working efficiency can be improved.

Referring to fig. 2, a first welding flange seat plate 101 is disposed at a communication position of the stop check valve 4 and the tank 1, and a second welding flange seat plate 102 is disposed at a connection position of the stop check valve 4 and the water outlet 23 of the first section of the injection pipe. One end of the stop check valve 4 and the cabin cabinet 1 are welded with each other through a first welding flange seat plate 101 and communicated together, the other end of the stop check valve 4 is communicated with the water outlet end of the first section of the injection pipe 2 through a second welding flange seat plate 102, and a fixing screw is arranged at the communicated position, so that the fixing performance of the stop check valve and the injection pipe is improved.

Referring to fig. 1, when the pipeline between the remote control valve 5 and the stop check valve 4 needs to be repaired, the pump 6 and the stop check valve 4 are closed, and then the relief valve 7 is opened;

after the maintenance is finished, the stop check valve 4 is opened, and then the remote control valve 5 is opened.

Under normal conditions, the drain valve 7 is closed first, then the pump 6 is started, water performs impact motion from the pump 6 towards the direction of the remote control valve 5, when the water passes through the second-stage injection pipe 3 and reaches the remote control valve 5, the remote control valve 5 is opened, the water enters the first channel 21 and the second channel 22 of the first-stage injection pipe 2 along with the opening of the remote control valve 5 and then moves towards the direction of the cabin cabinet 1 along the first channel 21 and the second channel 22, the stop check valve 4 is opened at the moment, the water enters the cabin cabinet 1, when the content of the cabin cabinet 1 is full of water, the stop check valve 4 is closed, the pump 6 is stopped, the drain valve 7 is opened, when the water in the first channel 21 and the second channel 22 all flows into the second-stage injection pipe 3, the remote control valve 5 is closed, the water in the second-stage injection pipe 3 is all discharged through the drain valve 7, and the water supply process is ended. In the water supply process, when the pipeline of the injection pipe between the stop check valve 4 and the remote control valve 5 is broken, the pumping 6 and the stop check valve 4 are firstly closed, the loss of water is reduced, then the discharge valve 7 is opened, the water is completely discharged through the discharge valve 7, at the moment, the pipeline between the stop check valve 4 and the remote control valve 5 is arranged to be checked and maintained, after the maintenance is finished, normal water supply can be continued, the water hammer effect is mainly avoided by opening the stop check valve 4 and then opening the remote control valve 5, the gravity impact of the liquid on the pumping 6 can be reduced, if the first section injection pipe 2 and the second section injection pipe 3 are arranged to be shorter, the remote control valve 5 is arranged to the bottom and is convenient to operate, the mode that the remote control valve 5 is arranged at the tail end of the cabin cabinet 1 can also be adopted, and the cost is saved.

Referring to fig. 1, the remote control valve 5 can be opened or closed manually or by remote control;

when the pump 6 has a fault, the stop check valve 4 is closed, the remote control valve 5 is closed, and the relief valve 7 is opened; or the remote control valve 5 is closed firstly, and the release valve 7 is opened.

Referring to fig. 1, when the pipeline between the remote control valve 5 and the pump 6 needs to be repaired, the check valve 4 is closed, then the remote control valve 5 and the pump 6 are closed, and the relief valve 7 is opened;

after the maintenance is finished, the check valve 4 is opened, then the discharge valve 7 is closed, and the pump 6 and the remote control valve 5 are opened.

In the water supply process, when needing to overhaul the pipeline between remote control valve 5 and the pump 6, close stop check valve 4 earlier, prevent that the water in the cabin 1 from flowing back, then stop pump 6, open bleeder valve 7 when closing remote control valve 5, reduce certain moisture loss, when waiting that moisture is all discharged, then inspect and maintenance work. When the pump 6 suddenly breaks down in the water supply process, the stop check valve 4 or the remote control valve 5 is closed, the remote control valve 5 or the stop check valve 4 is closed, then the discharge valve 7 is opened for water discharge work, and the inspection and the maintenance are carried out after the water discharge work is finished.

The addition of the stop check valve 4 also enables the stability of the ship to be more reliable, the quick overhaul can be realized, the double-valve isolation effect of the stop check valve 4 and the remote control valve 5 is better, the stability is enhanced, meanwhile, the loss of liquid, such as fuel leakage, is also reduced, and the leakage protection effect is good no matter the cleaning of a cabin, the damage of equipment or the loss of fuel per se.

The ship cabin cabinet device and the maintenance method provided by the invention can be used for quickly maintaining the pipeline, and the overall working efficiency is improved.
