Description

Technical Field

[0001] The invention belongs to the technical field of refueling pipeline manufacturing, and in particular relates to a medium transmission hose and a medium transmission hose. Background Art

[0002] The aircraft fuel filling location is far from the refueling control equipment. During the actual operation, the operators at the two locations need to communicate frequently to confirm the operation information, start and stop the operation timing, etc., which greatly limits the operation efficiency. At the same time, at the end of the refueling operation, the hose docking device is full of oil, and the hose is too heavy during the recovery process. There are problems such as a large number of operation support personnel and high labor intensity, which also seriously affects the operation efficiency. Therefore, in order to achieve efficient aircraft refueling support, there is an urgent need for a lightweight hose that can realize signal transmission to support the aircraft side support and lightweight recovery during the aircraft refueling process.

These two signal transmission methods have been applied to non-suckable flat rubber hoses. However, considering the application in suckable flat rubber hoses, for the method of pre-embedded signal lines, since the wall of the suckable flat hose needs to be continuously compressed and expanded, and the strength of the signal line and the rubber hose is difficult to unify, it is very easy for the rubber to be damaged or the signal line to break, which seriously affects the service life of the hose; for the method of passing the signal line through the inner cavity of the hose, after the excess oil in the hose is sucked out, the part of the suckable flat hose that wraps the signal line will obviously protrude, becoming a relatively weak point in the hose structure, which seriously affects the service life of the hose, and since the position of the signal line relative to the suckable flat hose is uncontrollable each time, it is impossible to strengthen it locally.

[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] The aircraft fuel filling location is far from the refueling control equipment. During the actual operation, the operators at the two locations need to communicate frequently to confirm the operation information, start and stop the operation timing, etc., which greatly limits the operation efficiency. At the same time, at the end of the refueling operation, the hose docking device is full of oil, and the hose is too heavy during the recovery process. There are problems such as a large number of operation support personnel and high labor intensity, which also seriously affects the operation efficiency. Therefore, in order to achieve efficient aircraft refueling support, there is an urgent need for a lightweight hose that can realize signal transmission to support the aircraft side support and lightweight recovery during the aircraft refueling process.

[0024] The lightweighting of the hose can be approached from two perspectives: lightweighting of the hose body itself and removal of excess oil from the hose. Currently, the existing suckable flat rubber hoses basically meet the requirements for lightweighting of hoses. The ways to achieve signal transmission in hoses include pre-embedded signal lines in the hose wall and passing signal lines through the inner cavity of the hose. These two signal transmission methods have been applied to non-suckable flat rubber hoses. However, considering the application in suckable flat rubber hoses, for the method of pre-embedded signal lines, since the wall of the suckable flat hose needs to be continuously compressed and expanded, and the strength of the signal line and the rubber hose is difficult to unify, it is very easy for the rubber to be damaged or the signal line to break, which seriously affects the service life of the hose; for the method of passing the signal line through the inner cavity of the hose, after the excess oil in the hose is sucked out, the part of the suckable flat hose that wraps the signal line will obviously protrude, becoming a relatively weak point in the hose structure, which seriously affects the service life of the hose, and since the position of the signal line relative to the suckable flat hose is uncontrollable each time, it is impossible to strengthen it locally.

[0025] The embodiment of the present invention provides a manufacturing process of a medium transmission hose, which can extend the service life of the hose and reduce the risk of breakage of a signal line.

[0026] The following is combined with the accompanying drawings of the specification Figure 1 to Figure 4 A specific description is given for the media transport hose.

[0027] Figure 2 It is a structural diagram of the hose in an expanded state. At this time, the hose is in an oil transportation condition and is subjected to positive pressure. The overall shape of the hose is quasi-circular, and the dumbbell and free bending parts of the tube wall are stretched open. The signal transmission harness 4 embedded in the middle part of the tube wall will move with the tube wall, but the deformation of the tube wall at this location is small.

[0028] Figure 3 This is a structural schematic diagram of the hose in the flattened state. At this time, the hose is in the residual oil condition in the recovery pipe and is subjected to negative pressure. The overall shape of the hose is dumbbell-shaped, and the walls of the dumbbell parts at both ends are circular. The free bending part is sucked flat to a state where it almost touches the inner wall of the hose, and the middle part still maintains a quasi-circular state.

[0029] The present application provides a manufacturing process for a medium transmission hose, which includes the following steps: manufacturing a tubular inner lining layer 1; inserting a circular fixed core shaft inside the inner lining layer 1, and the outer surface of the fixed core shaft is in contact with the inner surface of the inner lining layer 1; wrapping a reinforcing layer 2 on the outer surface of the inner lining layer 1; laying a signal transmission harness 4 on the outer surface of the reinforcing layer 2; wrapping a protective layer 5 on the outer surface of the signal transmission harness 4; vulcanizing the tubular structure formed by the inner lining layer 1, the reinforcing layer 2, the signal transmission harness 4 and the protective layer 5; detaching the fixed core shaft from the inner lining layer 1; inserting a shaping core shaft inside the inner lining layer 1; and molding and shaping the inner lining layer 1, the reinforcing layer 2, the signal transmission harness 4 and the protective layer 5.

[0030] Specifically, the manufacturing process of the medium transmission hose includes the following steps: making a tubular lining layer 1; inserting a circular fixed core shaft inside the inner lining layer 1, the outer surface of the fixed core shaft fits the inner surface of the inner lining layer 1, and the fixed core shaft is used to support the inner lining layer 1; wrapping a reinforcing layer on the outer surface of the inner lining layer 1 to ensure that when subjected to negative pressure, the hose part with the embedded signal transmission harness can still maintain its structural shape to prevent the signal transmission harness 4 from bending and breaking due to the negative pressure on the hose; laying the signal transmission harness 4 on the outer surface of the reinforcing layer 2 to achieve stable and reliable signal transmission; wrapping a protective layer 5 on the outer surface of the signal transmission harness 4, the protective layer 5 makes the entire medium transmission hose have It has the functions of being resistant to wear, outdoor exposure and petroleum-based fuel; the tubular structure formed by the inner lining layer 1, the reinforcement layer 2, the signal transmission harness 4 and the protective layer 5 is vulcanized to improve the strength and elasticity of the medium transmission hose; the fixed core shaft is separated from the inner lining layer 1, and the shaping core shaft is inserted into the inner lining layer 1, and the inner lining layer 1, the reinforcement layer 2, the signal transmission harness 4 and the protective layer 5 are molded and shaped, so that the medium transmission hose has the shape of the inserted shaping core shaft, so that the medium transmission hose can expand when subjected to positive pressure to realize oil transportation, and can maintain the basic shape of the hose when subjected to negative pressure, so that the medium transmission hose can maintain a stable structure in all working conditions.

[0031] Furthermore, vulcanization of the tubular structure formed by the inner lining layer 1, the reinforcement layer 2, the signal transmission harness 4 and the protective layer 5 has the following advantages: improving strength and elasticity. The vulcanization treatment can transform the molecular structure of the rubber from a linear structure to a three-dimensional mesh structure. This structure enhances the interaction between the molecular chains, thereby significantly improving the strength and elasticity of the rubber. When subjected to external forces, the vulcanized rubber can better resist deformation and fracture. Improve wear resistance and swelling resistance. The cross-linked bonds formed during the vulcanization process limit the movement of rubber molecules, reduce the wear and swelling of the rubber under friction and solvents, and enable the vulcanized rubber to maintain good performance stability during long-term use. Improve heat resistance and chemical stability. The formation of cross-linked bonds limits the thermal motion of the rubber molecular chain and improves the heat resistance of the rubber. At the same time, the cross-linking reaction reduces chemically active groups or atoms, making it difficult to carry out aging reactions and improving the chemical stability of the rubber.

[0032] Optionally, the medium transmission hose is a refueling hose used for refueling an aircraft.

[0033] In some optional embodiments, the step of laying the signal transmission harness 4 on the outer surface of the reinforcement layer 2 includes laying at least two signal transmission harnesses 4 on the outer surface of the reinforcement layer 2, the signal transmission harnesses 4 are arranged circumferentially on the surface of the lining layer 1, and any two signal transmission harnesses 4 are symmetrical about the center line of the lining layer 1. The signal transmission harness 4 includes a plurality of signal transmission lines 41, and there is a preset distance between any two signal transmission lines 41, and each signal transmission line 41 is serpentine.

[0034] Furthermore, any signal transmission harness 4 is bent in a snake-like shape to prevent the signal transmission harness 4 from being broken due to the change in length when the hose is in working state. Two signal transmission harnesses 4 are laid on the outer surface of the reinforcement layer 2. The two signal transmission harnesses 4 are symmetrical about the center line of the lining layer 1. The circular curved part in the middle of the medium transmission hose is reinforced by the reinforcement layer 2 to ensure that when subjected to negative pressure, the hose part embedded with the signal transmission harness 4 can still maintain its structural form, preventing the signal transmission harness 4 from bending due to the negative pressure on the hose and causing breakage. Figure 1 As shown, the signal transmission harness 4 is evenly arranged in a ring shape in the wall of the middle quasi-circular medium transmission hose. The signal transmission harness 4 is arranged between the reinforcement layer 2 and the protective layer 5. The signal transmission harness 4 extends along the length direction of the medium transmission hose and is arranged in an S-shaped snake shape to prevent the signal transmission harness 4 from being broken due to the change in length when the hose is in operation. When oil is transported outward through the medium transmission hose, the medium transmission hose is subjected to positive pressure, the free bending part of the medium transmission hose is stretched, and the entire medium transmission hose expands into a quasi-circular shape. The expansion state of the hose is as shown in FIG. Figure 2 As shown in the figure; when the residual oil in the medium transmission hose is sucked out, the medium transmission hose is subjected to negative pressure, the free bending part of the hose is flattened, and the hose is basically dumbbell-shaped, as shown in the figure. Figure 3 shown.

[0035] like Figure 1 As shown, Figure 1 The schematic diagram of the structure of the medium transmission hose in the initial state, at which time the medium transmission hose is not under pressure, and the overall shape of the medium transmission hose is dumbbell-like, the tube walls of the dumbbell parts at both ends and the middle part are circular, and the tube walls of the rest of the parts are in a free bending state. The medium transmission hose is partially reinforced in the middle circular tube wall by a densely woven fabric reinforcement layer 2, and on the basis of maintaining the basic shape of the initial state and the sucked flat state of this part, a groove is set on the outer surface of the fabric reinforcement layer 2, and the groove is used to embed the signal transmission line 41 to fix the signal transmission line 41, and the depth of the groove matches the diameter of the signal transmission line 41 to ensure that the protective layer 5 of the medium transmission hose after forming can be circumferentially uniform without bulges caused by the embedded signal transmission line 41.

[0036] Figure 2 It is a structural schematic diagram of the medium transmission hose in the expanded state. At this time, the medium transmission hose is in the oil transportation condition and is subjected to positive pressure. The overall shape of the medium transmission hose is quasi-circular, and the dumbbell and free bending parts of the pipe wall are stretched open. The signal transmission line 41 embedded in the middle part of the pipe wall will move with the pipe wall, but the deformation of the pipe wall at this location is small.

[0037] Figure 3 This is a structural schematic diagram of the medium transmission hose in the flattened state. At this time, the medium transmission hose is in the residual oil condition in the recovery pipe and is subjected to negative pressure. The overall shape of the medium transmission hose is dumbbell-shaped, and the walls of the dumbbell parts at both ends are circular. The free bending part is sucked flat to a state where it is almost in contact with the inner wall of the medium transmission hose, and the middle part still maintains a quasi-circular state.

[0038] The present application also provides a medium transmission hose, which is made by any of the processes mentioned above, and includes: a tubular lining layer 1; a reinforcement layer 2, arranged on the outer surface of the tubular lining layer 1, and the inner surface and the outer surface of the lining layer 1; a signal transmission harness 4, laid on the outer surface of the reinforcement layer 2; and a protective layer 5, wrapping the signal transmission harness 4.

[0039] Specifically, the medium transmission hose includes an inner lining layer 1, a reinforcement layer 2, a signal transmission harness 4 and a protective layer 5 which are stacked from the inside to the outside. The manufacturing process of the medium transmission hose includes the following steps: manufacturing a tubular inner lining layer 1; inserting a circular fixed core shaft inside the inner lining layer 1, the outer surface of the fixed core shaft fits with the inner surface of the inner lining layer 1, and the fixed core shaft is used to support the inner lining layer 1; wrapping the reinforcement layer 2 on the outer surface of the inner lining layer 1 to ensure that when subjected to negative pressure, the hose portion with the embedded signal transmission line 41 can still maintain its structural shape, and prevent the signal transmission harness 4 from bending and then breaking due to the negative pressure on the hose. Molding makes the medium transmission hose have the shape of the inserted molding core shaft, so that the medium transmission hose can expand when subjected to positive pressure to achieve oil transportation, and can maintain the basic shape of the hose when subjected to negative pressure, so that the medium transmission hose can maintain a stable structure in all working conditions. The signal transmission harness 4 is laid on the outer surface of the reinforcement layer 2 to achieve stable and reliable signal transmission, the fixed core shaft is detached from the inner lining layer 1, and the shaping core shaft is inserted into the inner lining layer 1 to achieve stable and reliable signal transmission, and the outer surface of the signal transmission harness 4 is wrapped with a protective layer 5. The protective layer 5 makes the entire medium transmission hose resistant to wear, outdoor exposure and petroleum-based fuel. The outer surface of the protective layer 5 is vulcanized to improve strength and elasticity.

[0040] Furthermore, the medium transmission hose is dumbbell-shaped after molding. The dumbbell-shaped hose structure can expand when subjected to positive pressure to achieve oil transportation, and can maintain the basic shape of the hose when subjected to negative pressure, without obvious bending angles, and is suitable for the working conditions of repeatedly recovering residual oil. In addition, by providing a groove in the reinforcement layer 2, and arranging the signal transmission line 41 in the groove, stable and reliable signal transmission is achieved by means of the structure that can maintain a stable state under all working conditions. The inner lining layer 1 and the protective layer 5 are both made of rubber. This rubber hose structure can take into account both signal transmission and residual oil recovery, and can effectively support the aircraft side support and lightweight recovery during the aircraft refueling process, thereby improving the efficiency of aircraft refueling support.

[0041] In some optional embodiments, the material of the lining layer 1 and the protective layer 5 is rubber.

[0042] Specifically, the protective layer 5 is made of rubber. This rubber hose structure can take into account both signal transmission and residual oil recovery, and can effectively support on-board support and lightweight recovery during aircraft refueling, thereby improving aircraft refueling support efficiency.

[0043] In some optional embodiments, the medium transmission hose includes at least two signal transmission harnesses 4, which are arranged circumferentially on the surface of the inner lining layer 1, and any two signal transmission harnesses 4 are symmetrical about the center line of the inner lining layer 1, and the signal transmission harnesses 4 are serpentine. The signal transmission harness 4 includes a plurality of signal transmission lines 41, and there is a preset distance between any two signal transmission lines 41, and each signal transmission line 41 is serpentine.

[0044] In some optional embodiments, the reinforcement layer 2 is provided with a plurality of grooves matching the signal transmission line 41 , one signal transmission line 41 matches one of the grooves, and the signal transmission line 41 is clamped in the groove.

[0045] In some optional embodiments, the reinforcement layer 2 is a densely woven layer.

[0046] In some optional embodiments, the lining layer 1 and the protective layer 5 are rubber layers.

[0047] In some optional embodiments, the tubular structure formed by the inner lining layer 1, the reinforcement layer 2, the signal transmission harness 4 and the protective layer 5 is vulcanized, which has the following advantages: improving strength and elasticity. The vulcanization treatment can transform the molecular structure of the rubber from a linear structure to a three-dimensional mesh structure. This structure enhances the interaction between the molecular chains, thereby significantly improving the strength and elasticity of the rubber. When subjected to external forces, the vulcanized rubber can better resist deformation and fracture. Improve wear resistance and swelling resistance. The cross-linked bonds formed during the vulcanization process limit the movement of rubber molecules, reduce the wear and swelling of the rubber under friction and solvent action, and enable the vulcanized rubber to maintain good performance stability during long-term use. Improve heat resistance and chemical stability. The formation of cross-linked bonds limits the thermal motion of the rubber molecular chain and improves the heat resistance of the rubber. At the same time, the cross-linking reaction reduces the chemically active groups or atoms, making it difficult to carry out the aging reaction and improving the chemical stability of the rubber.

[0048] The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
