Abstract
The invention discloses a waterproof hammer structure of an injection pipeline of a ship cabin, which relates to the field of ship construction and comprises a suction pipeline, a reverse U-shaped bent pipe and a ventilation valve, wherein the suction pipeline is connected to a water source and supported on a main deck; the inverted U-shaped elbow is further connected to an injection pipe in the cabin through a flange, and the injection pipe in the cabin vertically extends downwards into the liquid cabin. The invention solves the water hammer phenomenon which can occur when the injection pipe of the liquid cabin is injected into the liquid cabin.
Description
Technical Field
The invention relates to the field of ship construction, in particular to a waterproof hammer structure of a ship cabin injection pipeline.
Background
The ship is provided with liquid tanks according to the needs, and part of the liquid tanks need to be filled with liquid media from the deck through pipelines. Liquid medium from the suction pipe is discharged into the cabin through the injection pipe in the cabin through the pump, when the pump is started, liquid is discharged into the cabin in the moment due to pressure discharge of the pump, and because the injection pipe is a vertical pipeline, the liquid is subjected to gravity action to cause a vacuum pipeline section to appear in the part of pipelines in the moment, and the liquid in the pipeline flows back and generates huge backflow pressure to form a water hammer along with atmospheric pressure through the air head of the cabin and the atmospheric pressure in the cabin to press the liquid in the cabin to the vacuum pipeline section. The water hammer causes pipeline vibration by a light person and damages a pump and a pipeline by a heavy person, thereby affecting the operation safety of the ship.
Disclosure of Invention
The invention aims to provide a water hammer prevention structure for an injection pipeline of a ship cabin, so as to prevent the water hammer phenomenon from occurring when an injection pipe of a liquid cabin is injected.
In order to achieve the purpose, the invention adopts the following technical scheme:
a waterproof hammer structure for an injection pipeline of a ship cabin comprises a suction pipeline which is connected with a water source and supported on a main deck, wherein a pump is connected in series on the suction pipeline, one end of the suction pipeline, which is far away from the water source, is connected with an inverted U-shaped bent pipe through a deck check valve, and the top end of the inverted U-shaped bent pipe is communicated with a vent valve; the inverted U-shaped elbow is further connected to an injection pipe in the cabin through a flange, and the injection pipe in the cabin vertically extends downwards into the liquid cabin.
The intracabin injection pipe is formed by connecting a shorter horizontal pipe and a longer vertical pipe.
A horizontal tube is connected to the flange.
The vertical pipe vertically extends downwards into the liquid tank.
The horizontal pipe is connected with a first pipe clamp, and the first pipe clamp is supported and arranged on a first support fixed on the main deck.
And the vertical pipe is connected with a second pipe clamp, and the second pipe clamp is supported and arranged on a second support fixed on the inner wall of the cabin.
And a third pipe clamp is connected to the suction pipeline, and the third pipe clamp is supported and arranged on a third support fixed on the main deck.
Compared with the prior art, the ventilation valve has the advantages that when a vacuum pipe section is generated, external air can be introduced into the pipeline, and the vacuum pipe section is eliminated. The U-shaped bent pipe can increase resistance and reduce water hammer pressure. The deck check valve can prevent the damage of water hammer to the power source pump.

Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1, the water hammer preventing structure for the injection pipeline of the ship cabin comprises a suction pipeline 6 connected to a water source and supported on a main deck, wherein a pump 5 is connected in series on the suction pipeline 6, one end of the suction pipeline 6, which is far away from the water source, is connected to an inverted U-shaped elbow 2 through a deck check valve 4, and the top end of the inverted U-shaped elbow 2 is communicated with a vent valve 1; the inverted U-shaped elbow 2 is further connected to an injection pipe 3 in the tank through a flange 8, and the injection pipe 3 in the tank vertically extends downwards into the liquid tank.
The cabin injection pipe 3 is formed by connecting a shorter horizontal pipe and a longer vertical pipe.
The horizontal pipe is connected to said flange 8.
The vertical pipe vertically extends downwards into the liquid tank.
The horizontal pipe is connected with a first pipe clamp 9, and the first pipe clamp 9 is supported and arranged on a first support 10 fixed on the main deck.
And the vertical pipe is connected with a second pipe clamp, and the second pipe clamp is supported and arranged on a second support fixed on the inner wall of the cabin.
And a third pipe clamp is connected to the suction pipeline 6, and the third pipe clamp is supported and arranged on a third support fixed on the main deck.
When the invention is used, liquid medium from a suction pipeline 6 is discharged into a cabin B through a deck check valve 4, an inverted U-shaped bent pipe 2 and an injection pipe 3 in the cabin through a pump 5, the liquid is discharged into the cabin B instantaneously due to the pressure discharge of the pump 5 when the pump 5 is started, the vacuum pipeline section of the part of pipeline can be instantaneously generated due to the action of gravity as the injection pipe 3 in the cabin is mainly a vertical pipeline, the liquid enters gas and the liquid in the cabin with the atmospheric pressure C to the vacuum pipeline section through an air head 7 of the cabin, and the liquid in the pipeline flows back and generates huge backflow pressure to form a water hammer in the traditional structure. In the present invention, when a vacuum pipe section is generated, the vent valve 1 introduces external gas into the pipe to eliminate the vacuum pipe section. And the inverted U-shaped bent pipe 2 can increase resistance and reduce water hammer pressure. The deck check valve 4 will prevent damage to the power source pump 5 from water hammer.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical solutions and the inventive concepts of the present invention within the technical scope of the present invention.
