Description

The invention relates to shipbuilding, in particular to ship seawater systems.

The purpose of the invention is to provide the convenience of servicing the drainage system while verifying its operability by ensuring the supply of seawater to the drainage pump without flooding the compartment being serviced.

Figure 1 presents a diagram of a system located in one compartment; 2 is one of the devices for connecting the piping system}; FIG. 3 is a schematic of the shut-off valve; 4 is a general diagram of a system located in several compartments of a vessel.

The ship system contains pumps 1 for seawater, for example, for cooling the power plant, communicating through valves 2. With a common pressure pipe 3 to which consumers are connected, for example heat exchangers 4, which are connected through valves 5 to the outboard openings 6, and drainage pump (VON) 7, which is connected to the receiving pipeline 8, including the butterfly valve 9, with the hold of the compartment to be serviced and the pipeline 10 through the valve No outboard port 6 with the outboard medium The pipelines 8 and 3 are equipped with nozzles 12 and 13, which oedineny between a nozzle conduit 14. In the valve 13 is placed -15. On pipelines 10 and 14, pressure gauges 16 are installed. A test capacitor 17 is connected to the pipeline 14 at its lowest point with a sensor-detector 18 of water availability (with light or audible indication). A rotary plug 19 is provided for draining the water from the tank 17.

At the entrance of the pipeline 8 can be installed as a rotary valve 9, and a check valve 20 (figure 2).,

To increase reliability, a two-position valve 21 is used as a locking member, which connects the cooling system to the inlet of the bilge pump, the upper 22 and lower 23 flanges of which are connected by threaded fastener 24. The flange 22 is equipped with a casing 25 forming

A flat baffle 27, provided with a bore 28 and end stops 29 extreme positions.

5 When disposing of pumps 1 with nozzles 13 and sump pumps at a considerable distance from one another, including in different compartments, the use of a stationary metal pipeline clogs the compartments and causes inconvenience in their maintenance. In this case, the cutting points 12 and 13 are supplied with plugs 30 and interconnected with each other when checking the drainage pumps for operability through removable flexible hoses 31. The drainage pump 7 is located in one waterproof

The main pipeline 33 is connected with the hold of the adjacent compartment. Pump 1, pipe 3 and heat exchanger 4 are located in the same compartment and patra

25 side 13 of the pipeline 3 is fixed in a waterproof bulkhead 34 of the adjacent compartment. On the bulkheads installed glasses 35 with removable plugs.

The seawater system works as follows,

Under normal operating conditions, the pumps t and heat exchangers 4 are working, the valve 15 is closed, the pipelines 14 and 8 and the pipe 12 are dried, and the VON 7 is ready for operation. In case of violation of the tightness of the valve 15 outboard water flows into. the tank 17 of the stationary pipeline 14 fills it and occurs

  .18 sensor alarm (with light or sonic display). The personal composition restores the tightness of the valve 15, and the water from the tank 17 is discharged through

 plug 19. The system is reset. This provides control over the tightness of the pipeline 14 and eliminates the danger of flooding the room

DP check VON 7 open the valve 15 and start the pump, while the flow rate and pressure regulate the valve with us 5.15 and 11 by gauges 16. In the test mode, pumps 1 and 7 can

the cavity, which communicates with the entrance of VAN 7, 55, jointly work no more than 1 h.

Two-position shut-off valve 21 is equipped with sealing elements 26, between which is located

A flat sliding flap 27 is provided with a bore 28 and, with end stops 29 end positions.:

5 With the location of pumps 1 with nozzles 13 and drainage pumps at a considerable distance from one another, including in different compartments, the use of a stationary metal pipeline clogs the compartments and causes inconvenience in their maintenance. In this case, the nozzles 12 and 13 are supplied with plugs 30 and interconnected during the check of the efficiency of the drainage pumps by means of removable flexible hoses 31. The drainage pump 7 is located in one waterproof

compartment, the sump pump 32 is located in a different compartment and additional

The main pipeline 33 is connected with the hold of the adjacent compartment. Pump 1, pipe 3 and heat exchanger 4 are located in the same compartment and patra

the side 13 of the pipeline 3 is fixed in a waterproof bulkhead 34 of the adjacent compartment. On the bulkheads installed glasses 35 with removable plugs.

The seawater system works as follows,

Under normal operating conditions, the pumps t and heat exchangers 4 are working, the valve 15 is closed, the pipelines 14 and 8 and the pipe 12 are dried, and the VON 7 is ready for operation. When the tightness of the valve 15 is disturbed, the outboard water enters the tank 17 of the stationary pipeline 14, fills it and occurs

actuation of the sensor-alarm 18 (with light or sound indication). The personal composition restores the tightness of the valve 15, and the water from the tank 17 is discharged through

plug 19. The system is reset. This provides control over the tightness of the pipeline 14 and eliminates the danger of flooding the room to be served with the VAN 7.

DP check VON 7 open the valve 15 and start the pump, while the water flow and pressure regulate the valves 5,15 and 11 on the pressure gauge 16. In the test mode, pumps 1 and 7 can

work together usually no more than 1 hour.

When the on-off dump valve 21 is located at the outlet of the bilge pump, the transfer from the readiness mode of KHA 7 to the testing mode is carried out by moving the flat valve 27 to the extreme left position. For this, fasteners 24 are loosened, the flap is moved. 27 and tighten the fasteners. It should be noted that the proposed design due to the hermetic shut-off, the pipeline 8 ensures the stable operation of the drainage pump with intelligence and more receiving pipes.

When the seawater system is located in several compartments, the drainage pumps are checked by removing the plugs from the Pat5 cabin 12 and 13 and the bulkhead cups and connecting them with flexible hoses 31 so that the outlet of the seawater pumps through the discharge pipe 3 is connected to

 About the inlet of the sump pump to be tested.
