Description

Technical Field

[0001] The utility model relates to the technical field of pipe fittings, in particular to a highly corrosion-resistant ship pipeline. Background Art

[0002] Pipes are a widely used material, and pipes can have different characteristics depending on the application scenarios. For example, the existing Chinese patent with application number: 202121321819.X discloses a ship air-conditioning ventilation duct, including a ventilation pipe, wherein the ventilation pipe is provided with an air inlet channel and an air outlet channel interconnected with each other, and also includes a pressure regulating device connected to the air outlet channel, the pressure regulating device includes an adjusting plate slidably connected to the air outlet channel, and a reset assembly connected to the side of the adjusting plate away from the air inlet channel, the diameter of the air outlet channel is larger than that of the air inlet channel, and the adjusting plate rests on the end face of the air inlet channel under the action of the reset assembly.

[0003] Although the above technology has a certain degree of noise reduction effect when in use, in actual use, since no corresponding corrosion reduction components are provided, and the corrosiveness of water vapor in the ocean is relatively strong, the service life of the above pipeline is easily shortened due to corrosion by water vapor in the ocean. Therefore, in order to solve the above technical problems, we propose a highly corrosion-resistant ship pipeline. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a highly corrosion-resistant ship pipeline.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A highly corrosion-resistant ship pipeline comprises a first tube body and a second tube body which are connected to each other, wherein the first tube body is hingedly connected with an inner sealing plate on the upper side of one end inside the second tube body, a switch which matches the inner sealing plate is arranged on the side of the inner bottom surface of the second tube body close to the first tube body, an electric cylinder is installed on the end of the inner bottom surface of the second tube body away from the first tube body, the output end of the electric cylinder is connected with the outer sealing plate, and a matching receiving groove is arranged on the end of the second tube body away from the first tube body corresponding to the outer sealing plate.

[0007] Preferably, one end of the first tube body is in an outwardly expanded state and a trumpet-shaped cavity is provided inside the first tube body, and the large end of the trumpet-shaped cavity is located inside the second tube body and fits with the inner sealing plate.

[0008] Preferably, a plurality of spoiler columns are provided inside the trumpet-shaped cavity of the first tube body, and the spoiler columns are arranged in an interlaced manner.

[0009] Preferably, a mounting groove is provided on one side of the second tube body, and an observation window is provided in the mounting groove.

[0010] Preferably, guide cylinders are fixed at four corners inside the second tube body, a guide rod is slidably inserted inside the guide cylinder, and one end of the guide rod is fixed on the plate body of the peripheral sealing plate.

[0011] Preferably, a sealing ring is installed on one side of the plate body of the peripheral sealing plate corresponding to the accommodating groove of the second tube body, and the cross-section of the second tube body is rectangular.

[0012] Preferably, the end surface of the first tube body at one end inside the second tube body is in an inclined state, and the inclined surface faces obliquely upward.

[0013] The utility model provides a highly corrosion-resistant ship pipeline, which has the following beneficial effects:

[0014] 1: In the utility model, after the turbid gas in the ship room enters the first tube body, the turbid gas moves along the first tube body until it enters the second tube body. In this process, the gas pushes the inner sealing plate, that is, the switch starts the electric cylinder at this time, and the output end of the electric cylinder pushes the outer sealing plate to move outward. When there is no need for ventilation in the room, the gas in the first tube body does not flow, so that under the action of gravity, the inner sealing plate is automatically flipped down and reset until the outer sealing plate blocks the end of the second tube body. In summary, during the use of this scheme, the inner sealing plate and the outer sealing plate are set to automatically block the pipeline, so that during the use of the pipeline, it can timely avoid the excessive entry of external corrosive water vapor into the pipeline and cause corrosion to it. That is, the ship pipeline proposed in this scheme has better noise reduction effect than the traditional scheme, and also makes the inner wall of the pipeline have better resistance to ocean water vapor.

[0015] 2: The setting of the trumpet-shaped cavity in the utility model makes it possible for the gas to flow from the first tube body into the second tube body, and the gas flow rate decreases due to the increase in the pipe cross-section, thereby achieving a certain degree of silencing effect, thereby reducing noise; the setting of the spoiler column makes the gas collide and interfere with each other when passing through the trumpet-shaped cavity, thereby further reducing and disrupting the gas flow rate and flow direction, thereby causing the gas to rub against each other and reduce energy, thereby further achieving the effect of reducing noise; the setting of the observation window allows personnel to easily observe the operating status of each component in the second tube body without disassembling the pipeline, so as to facilitate timely maintenance; the setting of the guide rod and the guide cylinder improves the stability of the outer sealing plate when it moves; the setting of the sealing ring makes the sealing between the outer sealing plate and the end of the second tube body better, thereby better isolating the pipeline from corrosion by external water vapor when the air conditioner is not in use.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Example 1

[0025] Reference Figure 1-6 A highly corrosion-resistant ship pipeline comprises a first tube body 1 and a second tube body 2 which are connected to each other. An inner sealing plate 9 is hingedly connected to the upper side of the first tube body 1 located at one end inside the second tube body 2. A matching switch 10 is provided on the side of the inner bottom surface of the second tube body 2 close to the first tube body 1 corresponding to the inner sealing plate 9. An electric cylinder 8 is installed on the end of the inner bottom surface of the second tube body 2 away from the first tube body 1. The output end of the electric cylinder 8 is connected to the outer sealing plate 3. A matching accommodating groove is provided on the end of the second tube body 2 away from the first tube body 1 corresponding to the outer sealing plate 3.

[0026] Example 2

[0027] Reference Figure 1-6 , when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0028] One end of the first tube body 1 is in an outward expansion state and is provided with a trumpet-shaped cavity 12 inside. The large end of the trumpet-shaped cavity 12 is located inside the second tube body 2 and fits with the inner sealing plate 9. The trumpet-shaped cavity 12 is provided so that when the gas flows from the first tube body 1 to the second tube body 2, the gas flow rate decreases due to the increase in the pipe cross-section, thereby achieving a certain degree of silencing effect, thereby reducing noise; the trumpet-shaped cavity 12 of the first tube body 1 is provided with a plurality of interference flow columns 11, and the spoiler columns 11 are arranged in an interlaced manner. The arrangement of the spoiler columns 11 makes the gas collide and interfere with each other when passing through the trumpet-shaped cavity 12, thereby further reducing and disturbing the gas flow rate and flow direction, thereby causing the gas to rub against each other and reduce energy, thereby further achieving the effect of reducing noise; a mounting groove is provided on one side of the second tube body 2, and an observation window 5 is provided in the mounting groove. The arrangement of the observation window 5 allows personnel to conveniently observe the operating status of each component in the second tube body 2 without disassembling the pipeline, so as to facilitate timely maintenance.

[0029] Guide cylinders 7 are fixed at the four corners inside the second tube body 2, and a guide rod 6 is slidably inserted inside the guide cylinder 7. One end of the guide rod 6 is fixed on the plate body of the outer sealing plate 3. The setting of the guide rod 6 and the guide cylinder 7 improves the stability of the outer sealing plate 3 when it moves; a sealing ring 4 is installed on one side of the plate body of the outer sealing plate 3 corresponding to the accommodating groove of the second tube body 2. The cross-section of the second tube body 2 is rectangular. The setting of the sealing ring 4 makes the sealing between the outer sealing plate 3 and the end of the second tube body 2 better, thereby better isolating the corrosion of the pipeline by external water vapor when the air conditioner is not in use; the end face of the first tube body 1 at one end inside the second tube body 2 is in an inclined state, and the inclined surface faces obliquely upward. The setting of this inclined surface makes it possible for the inner sealing plate 9 to fit tightly against the end of the trumpet-shaped cavity 12 when there is no gas flowing in the first tube body 1, thereby facilitating the triggering of the switch 10.

[0030] Principle and advantages of use: During the use of the utility model, the first tube body 1 and the second tube body 2 are connected to each other and installed on the external ship, and the outer wall is wrapped with a protective layer, and the first tube body 1 is the air inlet pipe, and the second tube body 2 is the air outlet pipe. Then, when the turbid gas in the ship room enters the first tube body 1, the turbid gas moves along the first tube body 1 until it enters the second tube body 2. In this process, the gas pushes the inner sealing plate 9, that is, the inner sealing plate 9 flips upward, thereby disengaging from the switch 10, and at this time the switch 10 starts the electric cylinder 8. The output end of the electric cylinder 8 pushes the outer sealing plate 3 to move outward, that is, at this time the second tube body 2 is opened, so that the turbid air is discharged to the outside. When there is no need for ventilation in the room, the gas inside the first tube body 1 does not flow, so that under the action of gravity, the inner sealing plate 9 is automatically flipped downward and reset until the lower end of the inner sealing plate 9 triggers the switch 10. At this time, the output end of the electric cylinder 8 contracts until the outer sealing plate 3 blocks the end of the second tube body 2, thereby preventing the highly corrosive air from the outside from entering the pipe and causing corrosion to it.

[0031] At the same time, in the above process, if the gas flow rate and pressure flowing out of the first tube body 1 are less than the external wind pressure, that is, when the wind in the external ocean directly enters the first tube body 1, the inner sealing plate 9 is automatically flipped downward due to the flow of this wind, thereby controlling the electric cylinder 8 to drive the outer sealing plate 3 to seal the second tube body 2, thereby preventing the pipeline from being subsequently corroded by water vapor; in summary, during the use of this scheme, the pipeline can be automatically sealed by setting the inner sealing plate 9 and the outer sealing plate 3, so that during the use of the pipeline, it can be timely prevented from excessively entering the interior of the pipeline by external corrosive water vapor and causing corrosion to it, that is, the ship pipeline proposed in this scheme has better noise reduction effect than the traditional scheme, and also makes the inner wall of the pipeline have better resistance to ocean water vapor.

[0032] It should be further explained that the setting of the trumpet-shaped cavity 12 makes the gas flow rate decrease due to the increase in the pipe cross-section when the gas flows from the first tube body 1 to the second tube body 2, thereby achieving a certain degree of silencing effect, thereby reducing noise; the setting of the spoiler column 11 makes the gas collide and interfere with each other when passing through the trumpet-shaped cavity 12, thereby further reducing and disrupting the gas flow rate and flow direction, thereby causing the gas to rub against each other and reduce energy, thereby further achieving the effect of reducing noise; the setting of the observation window 5 allows personnel to conveniently observe the operating status of each component in the second tube body 2 without disassembling the pipeline, so as to facilitate timely maintenance; the setting of the guide rod 6 and the guide cylinder 7 improves the stability of the outer sealing plate 3 when it moves; the setting of the sealing ring 4 makes the sealing between the outer sealing plate 3 and the end of the second tube body 2 better, thereby better isolating the pipeline from corrosion by external water vapor when the air conditioner is not in use.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
