Accompanying drawing explanation
The principle schematic of emergency fire pump part in Fig. 1 Sea-water fire-fighting system of the present invention.
Fig. 2 emergency fire pump valve control system of the present invention and circuit diagram, in figure, dotted line represents cable, and part solid line represents airline.
Embodiment
Such as Fig. 1, composition graphs 2 illustrates, the ingress at emergency fire pump 3 arranges a pneumatic remote control butterfly valve 4 (pump inlet valve), and is set to normally closed by the state of remote control butterfly valve, also it is exactly keep valve to be closing condition when normal/cruise, emergency fire pump and external dynamic sea is completely cut off and comes. And the switching operation button of remote control butterfly valve is set in the position (wheel house 8 and fire control station 9) that emergency fire pump starts, ensure can open this valve easily when starting emergency fire pump under emergency conditions.
In Fig. 1, label 1 represents main deck, and label 2 represents bow thruster and emergency fire pump room, label 5 is cargo hold (being generally NO.1 cargo hold), and label 6 is the empty cabin of bow, and label 7 represents the switch of remote control butterfly valve, respectively in wheel house and fire control station, label 21 is baseline. In addition in figure, A represents that emergency fire pump 3 is connected to fire chief road.
In addition, in the butterfly valve assembly of pneumatic remote control shown in Fig. 2 16, it is positioned on pneumatic remote control butterfly valve and drives the handwheel 14 setting up an opening and closing valve on head, for manual operation, at this valve of local operation, to make it to meet specification to the requirement of sea-valve. Under normal circumstances, the power resources of remote control butterfly valve are generally hydraulic pressure power pumping plant or primary air bottle, but these two power set are all arranged on cabin, if firing accident occurs in cabin, these two power set all can be in inefficacy state. And emergency fire pump uses when being exactly and to be occurred in cabin under the emergency situation such as firing accident for putting out place's fire such as cabin. If the imported valve of emergency fire pump adopts remote control butterfly valve like this, and power resources are common hydraulic pressure power pumping plant or primary air bottle, will cause cannot opening under emergency conditions, cause emergency fire pump to work. In order to address this problem, the present invention arranges the propulsion source of a little air container 12 as this valve at the boatswain's locker 11 (nacelle exterior) of bow, and the pressurized air in primary air bottle is charged in this little air container (in figure, D represents that compressed air inlet pipeline is connected to cabin primary air bottle) by pipeline and vacuum breaker 13, the capacity of air container at least to be met the air capacity of a switch-valve, this addresses the problem cabin catch fire after butterfly valve there is no the problem of propulsion source. In addition, the air outlet of air container 12 is stating the valve 31 arranging in boatswain's locker and driving described pneumatic remote control butterfly valve.
The switch of remote control Pneumatic butterfly valve is that the switch of magnetic valve 10 carrying out the outlet of Long-distance Control air container by electrical signal completes, in order to ensure to control this remote control butterfly valve in all cases, the power supply of this magnetic valve 10 of remote control is except (power supply is except main distributing board is connected with main distributing board B, also add road emergency source of electric power C (power supply is from emergency switchboard), it is connected with emergency switchboard, so just ensures all to be at the trip switch of normal/cruise and emergent state lower valve the state of electricity.
To sum up, Fig. 1 represents pipeline and the valve principle schematic of emergency fire pump part in container-ship Sea-water fire-fighting system. The imported valve of this graph expression emergency fire pump is remote control Pneumatic butterfly valve, this butterfly valve can carry out telemanipulation at wheel house, fire control station and boatswain's locker, and require, in order to meet specification, the handwheel being provided with local operation on this valve, it is convenient to local operation. The state of this valve is normally closed, the seawater this ensures that thered when normal/cruise in suction box and effective isolation of emergent fire-fighting, avoids seawater and epibiota to the corrosion of emergency fire pump, it is possible to reach the object extending the emergent fire-fighting life-span.
If not taking remote control butterfly valve to be used as the inlet valve of emergency fire pump, so, in order to ensure that emergency fire pump can be opened under emergency conditions immediately, it is set to often open by the state of inlet valve with regard to needing, seawater in so emergent seabed will be full of emergency fire pump under gravity, the impeller of pump is soaked in the seawater, and seawater and epibiota can accelerate the corrosion of impeller and associated components, will cause emergent fire-fighting maintenance in use for some time or replacing.
Fig. 2 represents operated pneumatic valve Controlling System and schematic circuit diagram. This graph expression control process of emergency fire pump inlet valve: the magnetic valve controlling air container outlet by being arranged on the electrical signal of the switchboard of valve remote control, when magnetic valve is opened, the driving head of air-operated drive Pneumatic butterfly valve, opens Pneumatic butterfly valve. Air container is arranged in the boatswain's locker away from cabin, and the power supply of remote control panel connects from main distributing board and emergency switchboard.
If not taking independent air container to drive the method for Pneumatic butterfly valve, so, when cabin catches fire, because the propulsion source in cabin lost efficacy, Pneumatic butterfly valve just cannot be opened, emergency fire pump also just cannot work, finally cause the inefficacy of Sea-water fire-fighting system, in addition, if not connecing from main distributing board and emergency switchboard by the power supply of remote control panel, when cabin can be caused equally to catch fire because of main distributing board power-off cannot Open valve, also just result in the fire that cannot put out in cabin.
The above; it is only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; any it is familiar with those skilled in the art in the technical scope of present disclosure; technical scheme and invention design thereof according to the present invention are equal to replacement or are changed, and all should be encompassed within protection scope of the present invention.
