Description

Technical Field

[0001] The invention relates to the technical field, and in particular to a cut-off unit of a marine quick-closing valve and a ship thereof. Background Art

[0002] In ship design, the quick-closing valve system of the main engine and generator fuel pipeline is crucial to engine room fire prevention. The system is operated by a pneumatically controlled three-way ball valve: when it is open, the control air is connected to keep the quick-closing valve open, and when it is closed, the pressure is released to trigger the quick-closing valve to cut off the oil. To avoid operational delays during a fire, the three-way ball valve is usually installed near the control room (5 meters away from the engine body), but this also increases the risk of accidental oil cut-off and shutdown caused by crew members accidentally touching it.

[0003] The existing technology prevents misoperation by adding protective devices (such as protective covers or locks), but there are obvious defects: the design lacks standardization: the appearance and structure of the protective devices are not uniform, which is easy to be omitted in the design, and the subsequent additions are costly due to space limitations; poor installation adaptability: the control room environment is complex, and non-standard protective devices often conflict with surrounding equipment, forcing them to be simplified or even cancelled; there is a contradiction between protection and efficiency: traditional devices (such as fixed covers) require unlocking steps, delaying emergency operations, and simple locks are prone to loosening and failure.

[0030] like Figure 1 As shown, a shut-off unit of a marine quick-closing valve according to a preferred embodiment of the present invention comprises a box body 1, which is arranged in a rectangular parallelepiped or cylindrical shape, and the interior of the box body 1 is hollowly arranged to form a receiving cavity, and the box body 1 comprises a switchable door for opening the internal receiving cavity; a horizontally arranged air main pipe 2 is arranged in the receiving cavity, and the air main pipe 2 runs through the box body 1, and the two ends of the air main pipe 2 are fixed to the box body 1 by detachable fixing members 10, and the air main pipe is detachably designed by the detachable fixing members 10, which facilitates the installation and removal of the air main pipe 2 and improves the internal accessories. The air main pipe 2 is connected to the air bottle on the outside to provide compressed air to the inside to maintain the opening of the quick-closing valve; the side of the air main pipe 2 is connected to the air branch pipe 3, and the air branch pipe 3 is vertically connected to the air main pipe 2 to send the compressed air out of the air main pipe 2; the end of the air branch pipe 3 facing away from the air main pipe 2 is connected to a three-way ball valve 4, and the three-way ball valve 4 is connected to a quick-closing valve control pipe 9, and the end of the quick-closing valve control pipe 9 is connected to the quick-closing valve of the generator; a control device 5, which is arranged on the three-way ball valve 4 to control the opening or closing of the three-way ball valve 4.

[0031] In the present application, the box body 1 is used as the shell of the cut-off unit of the marine quick-closing valve, and the air main pipe 2, the air branch pipe 3 and the three-way ball valve 4 are protected in the internal accommodating chamber, and the two ends of the air branch pipe 3 are respectively connected to the air main pipe 2 and the three-way ball valve 4. When in use, the compressed air from the control air bottle first enters the air main pipe 2, and then passes through different air branches 3 to the quick-closing valves of the main engine or each generator, so that the quick-closing valve is in an open state and the oil supply is normal. When it is necessary to close the oil circuit, the three-way ball valve 4 is cut off by the control unit, so that the compressed air and the quick-closing valve are disconnected, the supply of compressed air is cut off, and the quick-closing valve is closed to realize the cut-off of the oil circuit; the three-way ball valve 4, the air branch pipe 3, the air main pipe 2 and the protective device are designed as one, forming a modular product, which not only saves space, but also is easy to install and operate, and the cost is also reduced, solving the practical problem that the protection type of the quick-closing valve cut-off device of the main engine and the generator of the ship is uncertain and easy to design omissions.

[0032] In some embodiments of the present invention, the control device 5 includes a handle, which is connected to the valve core of the three-way valve. The handle is used as a physical control device 5. The valve core of the three-way valve can be rotated by directly turning the handle, thereby disconnecting the compressed air supply to the quick-closing valve, so that the quick-closing valve cuts off the oil supply to the generator, thereby ensuring the safety of the oil-electric system in a timely manner. Specifically, the handle is provided with a nameplate using the initials of English words for easy use in an international environment.

[0033] In some embodiments of the present invention, the control device 5 is electrically connected to a controller, which is electrically connected to an external computer.

[0036] In some embodiments of the present invention, one end of the air main pipe 2 extends to the outside of the box 1 and is connected to a control flange 7. The control flange 7 is arranged between the air main pipe and the air bottle to control the flow rate of compressed air from the air bottle into the air main pipe 2. The operator can dynamically adjust the control flange 7 according to the starting conditions of different generators to adjust the compressed air flow required by different numbers of quick-closing valves.

[0037] In some embodiments of the present invention, the air main pipe 2 is connected to multiple air branch pipes 3, and the multiple air branch pipes 3 are respectively connected to different generators, so that one air main pipe 2 can provide compressed air to the quick-closing valves of multiple generators; the air branch pipes 3 are arranged in parallel on one side of the air main pipe 2, and the distances between adjacent air branch pipes 3 are equal, which optimizes the space utilization in the box 1 and provides sufficient handle rotation space for each three-way ball valve 4.

[0038] In some embodiments of the present invention, the three-way ball valve 4 is further connected to an air discharge pipe 8, the other end of which is connected to the atmosphere, and the air discharge pipe 8 is used to discharge the compressed air in the quick-closing valve control pipe 9 between the three-way ball valve 4 and the quick-closing valve to achieve the cutting operation of the pneumatic quick-closing valve. After the valve core is rotated, the air discharge pipe 8 of the three-way ball valve 4 and the quick-closing valve control pipe 9 are opened, so that the quick-closing valve control pipe 9 is connected to the atmosphere to release pressure, and the quick-closing valve is closed to achieve the cutting of the oil circuit.

When in use, the compressed air from the control air bottle first enters the air main pipe 2, and then passes through different air branches 3 to the quick-closing valve of the main engine or each generator, so that the quick-closing valve is in an open state and the oil supply is normal. When the oil circuit needs to be closed, the three-way ball valve 4 is cut off by the control unit, so that the compressed air and the quick-closing valve are disconnected, the compressed air supply is cut off, the quick-closing valve is closed, and the oil circuit is cut off; the three-way ball valve 4, the air branch pipe 3, the air main pipe 2 and the protection device are designed as one body to form a modular product, which not only saves space, but also is easy to install and operate, and the cost is also reduced, solving the practical problem that the protection type of the quick-closing valve cutting device of the ship's main engine and generator is uncertain and easy to design omissions. A ship includes a cut-off unit of a marine quick-closing valve according to any of the above embodiments.

[0040] The working process of the present invention is as follows: the compressed air from the control air bottle first enters the air main pipe 2, and then passes through different air branches 3 to the quick-closing valves of the main engine or each generator, so that the quick-closing valve is in an open state and the oil supply is normal.
