Description

Technical Field

[0001] The invention relates to the technical field of metal hoses, and in particular to a shock-absorbing and fatigue-resistant metal hose and a processing technology thereof. Background Art

[0002] Metal hose is a flexible pipe composed of bellows and metal mesh, mainly used to connect fixed pipes and compensate for displacement in the pipe system. It is generally composed of bellows, mesh, joints and other structures. It has the advantages of high flexibility, pressure resistance and easy maintenance. It is widely used in fluid transportation in industrial pipe systems. In some special use environments, such as fluid transportation environments with high pressure and unstable pressure, the bellows in the metal hose will have a great impact, which will not only affect the service life of the metal hose, but also cause great vibration. Therefore, metal hoses with shock absorption and anti-fatigue properties are in great demand in the market.

[0003] For example, a Chinese patent application numbered 201711042422.5 discloses a corrugated metal hose with a shock-absorbing function, comprising an annular metal bellows and joints welded at both ends thereof, wherein the annular metal bellows is provided with an annular metal jacket on the outside of each wave crest, a glass fiber cloth layer is filled between the metal jacket and the annular metal bellows, a metal mesh sleeve is provided on the outside of the annular metal bellows, and the metal mesh sleeve is welded and fixed to the joints at both ends; the invention can achieve a better shock-absorbing effect by putting an annular metal jacket on the wave crest position of the annular metal bellows without hindering the bending of the bellows.

[0004] Similar to the above-mentioned corrugated metal hose with shock-absorbing function, the shock-absorbing effect is achieved mainly by filling some shock-absorbing objects at the wave crest position of the corrugated tube. However, in actual use, the fluid transported by the metal hose often has different characteristics. The effect of shock absorption only by the above-mentioned technology is very limited, and it is not possible to perform corresponding shock absorption according to the characteristics of the fluid transported by the metal tube to improve fatigue resistance. For example, when transporting high-pressure fluid with high pressure and unstable pressure, the metal hose may deform and over-stretch too quickly, which will cause the instantaneous impact force to destroy the elasticity and shock resistance of the metal hose. At this time, the required shock absorption ability is stronger, but ordinary metal tubes do not have the above performance. Therefore, a higher-performance shock-absorbing and fatigue-resistant metal hose is needed to solve the above technical problems. Summary of the invention

[0005] The purpose of the present invention is to provide a shock-absorbing and fatigue-resistant metal hose and a processing technology thereof, so as to solve the problems of poor shock-absorbing and fatigue-resistant performance and poor impact resistance of the existing metal hose.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A shock-absorbing and anti-fatigue metal hose comprises a bellows body, connecting seats are respectively arranged at the openings on both sides of the bellows body, a protective layer is commonly connected between the two connecting seats, and also comprises: an impact-resistant component, the impact-resistant component comprises a stabilizing member arranged on the inner wall of the protective layer, a plurality of stabilizing grooves are opened on the stabilizing member, and the wave crests of the bellows body are located in the corresponding stabilizing grooves; a buffer component, the buffer component comprises two buffer components arranged on the inner side of the protective layer, the buffer component also comprises a transmission pipe arranged in the protective layer, each of the buffer components is provided with a connecting groove, the two ends of the transmission pipe are respectively connected with the corresponding connecting grooves, and the buffer component and the transmission pipe are both filled with fluid.

[0008] Preferably, the input end of the bellows body is fixedly connected to the corresponding buffer component, and the side of the stabilizing component close to the output end is fixedly connected to the buffer component on that side.

[0009] Preferably, a plurality of liquid storage parts are provided on the transmission tube, the liquid storage parts are made of elastic material, and the transmission tube is connected with the liquid storage parts.

[0010] Preferably, the diameter of the transmission tube gradually increases from the input end to the output end.

[0011] Preferably, the fluid is a viscous liquid.

[0012] Preferably, an inner protective tube is provided inside the bellows body, the connecting seat on the input end side is slidably connected to the inner protective tube, and the connecting seat on the output end side is slidably connected to the bellows body.

[0013] Preferably, a reinforcement layer is fixedly provided between the two connection sockets, and the protective layer is located inside the reinforcement layer.

[0014] Preferably, each of the connecting seats is provided with a plurality of mounting holes.

[0015] Preferably, the buffer component is made of elastic material.

[0016] A vibration-absorbing and fatigue-resistant metal hose processing technology comprises the following specific steps:

[0017] S1. The inner protective tube and the bellows body are formed and assembled;

[0018] S2. Then, a stabilizer, a buffer and a protective layer are sequentially arranged on the outside;

[0019] S3. Align and match the transmission pipe with the connecting groove, and add fluid to the buffer and the connecting groove;

[0020] S4. The reinforcing layer is sleeved on the outside of the protective layer, and the connecting seat is respectively connected to the corrugated pipe body, the inner protective pipe and the reinforcing layer.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. By setting the stabilizing groove and the movable stabilizing part, when the bellows body is subjected to a large impact, the bellows body and the inner protective tube can be used to shrink first to resist part of the impact force and vibration. When the impact force of the fluid increases, the bellows body pushes the stabilizing part to move to overcome the increased impact force, thereby achieving the effect of enhancing the impact resistance and fatigue resistance.

[0023] 2. The inner protective tube can prevent the hard impurities contained in the fluid from impacting the bellows body and causing the bellows to rupture from the inside. The reinforcement layer can prevent external collisions from causing mechanical damage to the bellows body. The protective layer can block the garbage in the weaving gap between the metal braided layers of the reinforcement layer and the external air and moisture, thereby preventing the garbage and moisture from polluting and corroding the bellows body, and effectively increasing the overall impact resistance and service life of the bellows body.

[0024] 3. By setting up the buffer, when the bellows body is impacted, the bellows body can overcome the resistance of the fluid to pull the buffer on that side to stretch, and when the input end of the bellows body contacts the buffer, both the fluid and the buffer can play a shock-absorbing and buffering role on the bellows body.

[0025] 4. Through the interaction of the two buffers, one contracts and the other stretches, when the bellows body is impacted, the stroke of the bellows body is increased again, which plays a certain protective role on the bellows body and can increase the fatigue resistance and impact resistance of the bellows body.

[0026] 5. A buffer is provided at the output end of the fluid. On the one hand, the two buffers are connected through the connecting groove, the transmission pipe and the liquid storage part, so that the fluids in the two buffers can move and exchange, so that when the bellows body is subjected to a strong impact, the two buffers interact with each other to offset a part of the impact force; on the other hand, by providing the liquid storage part, after the buffer on the output end side is compressed, the liquid flows into the liquid storage part, so that the liquid storage part expands and contacts with the wave crest on the side of the bellows body close to the input end and performs flexibly resistance, thereby improving the impact resistance of the bellows body and strengthening the shock absorbing effect on the bellows body.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1

[0040] At present, when metal hoses are in use, due to the setting of the internal corrugations of the metal hoses, the fluid will hit the metal hoses when flowing inside the metal hoses, thereby generating a large impact force on the inside of the metal hoses. Long-term exposure to fluid impact will reduce the shock absorption and fatigue resistance of the metal hoses, thereby accelerating the damage of the metal hoses and reducing the service life of the metal hoses.

[0041] Please refer to the attached drawings of the instruction manual. Figures 1 to 6 The first embodiment of the present invention provides a shock-absorbing and anti-fatigue metal hose, including a bellows body 1, connecting seats 2 are respectively arranged at the openings on both sides of the bellows body 1, a protective layer 3 is commonly connected between the two connecting seats 2, and an impact-resistant component 4 is also included. The impact-resistant component 4 includes a stabilizing member 401 arranged on the inner wall of the protective layer 3, and a plurality of stabilizing grooves 402 are opened on the stabilizing member 401. The crest of the bellows body 1 is located in the corresponding stabilizing groove 402. An inner protective tube 101 is arranged inside the bellows body 1, the connecting seat 2 on the input end side is slidably connected to the inner protective tube 101, and the connecting seat 2 on the output end side is slidably connected to the bellows body 1, a reinforcing layer 6 is commonly fixed between the two connecting seats 2, and the protective layer 3 is located in the reinforcing layer 6 to prevent the protective layer 3 from being damaged by the outside, and a plurality of mounting holes 201 are opened on each connecting seat 2.

[0042] In specific use, the bellows body 1 is distinguished and installed by the shapes of the two ends and the connection methods with the connecting seat 2; Figures 2 to 8 As shown, the metal hose is then installed between the corresponding fluid devices through the connecting seat 2 and the mounting hole 201. This technology is prior art and will not be described in detail here.

[0043] When the fluid is input from the input end of the bellows body 1, the fluid flows in the inner protective tube 101. The setting of the inner protective tube 101 can prevent the fluid from directly impacting the bellows body 1 when there are foreign objects in the fluid, thereby avoiding causing internal mechanical damage to the bellows body 1 and protecting the interior of the bellows body 1. The reinforcing layer 6 is a metal braided layer, which can prevent the outer wall of the bellows body 1 from rupture after collision when it is hit from the outside. The protective layer 3 can prevent dust between the gaps woven by the reinforcing layer 6 from directly contacting the outer wall of the bellows body 1 and causing pollution and corrosion to the bellows body 1.

[0044] When the impact force of the fluid in the bellows body 1 and the inner protective tube 101 is large, the impact force of the fluid will push the bellows body 1 and the input end of the inner protective tube 101 to shrink and vibrate. When the bellows body 1 and the inner protective tube 101 shrink, the outer wall of the bellows body 1 contacts the inner wall of the stabilizing groove 402 on the stabilizing member 401, so as to dampen the bellows body 1 and control the vibration of the bellows body 1 within the range covered by the stabilizing groove 402, thereby preventing the bellows body 1 and the inner protective tube 101 from shrinking too quickly or too much, which would reduce the fatigue resistance and expansion and contraction ability of the bellows body 1, thereby ensuring the stable use of the bellows body 1.

[0045] Referring to the drawings of the specification Figure 2 , Figure 5 and Figure 6 It is understood that when the fluid impact force of the bellows body 1 and the inner protective tube 101 increases, the fluid impact force pushes the bellows body 1 and the inner protective tube 101 to contract again. Since the internal fluid impact force is relatively large at this time, after the bellows body 1 and the inner protective tube 101 contract to a certain extent, the outer wall of the bellows body 1 pushes the stabilizer 401 to move in the protective layer 3 through the inner wall of the stabilizing groove 402, thereby increasing the impact resistance and shock absorption capabilities of the bellows body 1 and the inner protective tube 101.

[0046] By providing the stabilizing groove 402 and the movable stabilizing member 401, when the bellows body 1 is subjected to a large impact, the bellows body 1 and the inner protective tube 101 can be firstly used to shrink by utilizing their shrinkage ability to resist a part of the impact force and vibration. When the impact force of the fluid increases, the bellows body 1 overcomes the increased impact force by pushing the stabilizing member 401 to move, thereby achieving the effect of enhancing the impact resistance, and controlling the vibration of the bellows body 1 within the range covered by the stabilizing groove 402, preventing the bellows body 1 and the inner protective tube 101 from shrinking too quickly, and preventing the bellows body 1 and the inner protective tube 101 from shrinking too much, and the bellows body 1 from shrinking too much, which leads to a reduction in the fatigue resistance and expansion and contraction ability of the bellows body 1, thereby ensuring the stable use of the bellows body 1. The inner protective tube 101 provided can prevent the hard impurities contained in the fluid from impacting the bellows body 1 and causing the bellows body 1 to rupture from the inside. The reinforcing layer 6 provided can prevent external collisions and the like from causing mechanical damage to the bellows body 1. The protective layer 3 can block garbage in the weaving gaps between the metal braided layers of the reinforcing layer 6 and external air, moisture, etc., to prevent the bellows body 1 from being polluted and corroded by garbage and moisture, thereby effectively increasing the impact resistance and service life of the bellows body 1.

[0047] Embodiment 2

[0048] In the above-mentioned embodiment 1, although the movable ability of the stabilizer and the stabilizing groove can provide a certain buffering and shock-absorbing ability for the metal hose, in actual use, when the impact force of the fluid is too large, the metal hose may be deformed and over-stretched too quickly, resulting in a decrease in the fatigue resistance and impact resistance of the metal hose, or even its disappearance.

[0049] Referring to the drawings of the specification Figures 1 to 9 It can be seen that the adopted technical solution includes a bellows body 1 and a buffer assembly 5. The buffer assembly 5 includes two buffer parts 501 arranged on the inner side of the protective layer 3. The buffer assembly 5 also includes a transmission tube 502 arranged in the protective layer 3. A connecting groove 503 is opened on each buffer part 501. The two ends of the transmission tube 502 are respectively connected with the corresponding connecting grooves 503. The buffer parts 501 and the transmission tube 502 are filled with fluid 504. The input end of the bellows body 1 is fixedly connected to the corresponding buffer part 501, and the side of the stabilizer 401 close to the output end is fixedly connected to the buffer part 501 on this side. Specifically, the fluid 504 is a viscous liquid, that is, a liquid with a relatively high viscosity, such as glycerin. The diameter of the transmission tube 502 gradually increases from the input end to the output end. A plurality of elliptical liquid storage portions 505 are provided on the transmission tube 502. The liquid storage portions 505 are made of elastic material. The transmission tube 502 is connected to the liquid storage portions 505. Among them, the buffer component 501 is made of elastic material, which can shrink after being squeezed and can stretch and extend after being pulled. After the pressure or tension disappears, it can automatically return to its original state.

[0050] In a specific application process, the buffer 501 is set in a natural state. When the impact force of the fluid on the bellows body 1 and the inner protective tube 101 is large, the impact force causes the bellows body 1 to shrink. The bellows body 1 is fixedly connected to the buffer 501 on the input end side. The bellows body 1 will pull the buffer 501 to stretch and deform. Since the viscosity of the fluid 504 is relatively large, when the bellows body 1 pulls the buffer 501 on the input end side to deform, it is necessary to overcome the viscous resistance of the fluid 504 in order to pull the buffer 501 on this side to deform. The buffer 501 can undergo elastic deformation and can gradually return to its natural state after the impact force of the fluid is reduced or disappears. The material of the buffer 501 and the fluid 504 are prior art and are not described in detail herein.

[0051] After the buffer member 501 on the input end side is deformed, the movement stroke of the bellows body 1 will increase, so that the bellows body 1 can move to a certain extent on the basis of the contraction of the bellows body 1. The bellows body 1 drives the stabilizing member 401 to move through the wave crest and the stabilizing groove 402, thereby reducing the impact of the fluid impact force on the bellows body 1 when the impact force is too large, and increasing the impact resistance and shock absorption capacity of the bellows body 1 from the side, so that when the impact force impacts the bellows body 1, the bellows body 1 always remains within its own impact resistance and fatigue resistance range, thereby ensuring the stability of the bellows body 1 when it is subjected to a large impact.

[0052] When the bellows body 1 is subjected to a greater impact force from the fluid, since a buffer component 501 fixedly connected to the stabilizing component 401 is provided on one side of the output end, and the two buffer components 501 are internally connected through the connecting groove 503 and the transmission tube 502 and the liquid storage portion 505, the transmission tube 502 has explosion-proof capability and can bend and deform to a certain extent, and the liquid storage portion 505 can expand when storing a certain amount of fluid 504. When the buffer component 501 on the input end side is stretched and extended by the bellows body 1, the buffer component 501 on the input end side can overcome a portion of the pulling force by utilizing the resistance of the internal fluid 504.

[0053] When the side of the bellows body 1 close to the input end and in contact with the buffer 501 is impacted and vibrated by the fluid, due to the high viscosity of the fluid 504, the buffer 501 will continue to be subject to the viscous resistance of the fluid 504 during the stretching deformation process. The slow movement of the fluid 504 in the buffer 501 and its own viscous resistance can offset part of the kinetic energy of the vibration of the bellows body 1 close to the input end, thereby delaying the contraction and movement of the bellows body 1. At the same time, when the bellows body 1 moves, the wave crest of the bellows body 1 contacts the side wall of the stabilizing groove 402, and the friction between the stabilizing member 401 and the protective layer 3 can slow down the movement of the bellows body 1.

[0054] And because the side of the stabilizing member 401 close to the output end is fixedly connected to the buffer member 501 on the output end side, the stabilizing member 401 will push the buffer member 501 on the output end side to contract. In the process of the stabilizing member 401 pushing the buffer member 501 on this side to contract, it is necessary to overcome the resistance of the fluid 504 to push the buffer member 501 on this side to contract. In the process of the buffer member 501 on this side contracting, the fluid 504 in the buffer member 501 gradually flows into the transmission tube 502, and when the bellows body 1 is impacted by the fluid, the fluid 504 plays a certain shock-absorbing role, thereby reducing the kinetic energy of the vibration at the end of the bellows body 1.

[0055] In the process of fluid 504 passing through transmission tube 502, since the diameter of transmission tube 502 gradually increases from the input end to the output end, that is, the side of transmission tube 502 close to the output end is thicker, and the side close to the input end is thinner, when the fluid 504 with high viscosity flows from the thick tube to the thin tube, on the one hand, due to the reduction in flow rate, the forward flow of fluid 504 is blocked, which can play a certain buffering role on the squeezed deformation of buffer 501, thereby enhancing the buffering effect of buffer 501, so that buffer 501 has a certain effect on the bellows itself. On the other hand, when the fluid 504 moves into the liquid storage part 505 through the transmission tube 502, the fluid 504 will expand the liquid storage part 505, so that the liquid storage part 505 contacts the wave crest of the bellows body 1 near the input end, and flexibly resists the wave crest. After the liquid storage part 505 expands to a certain extent, the wave crest of the bellows body 1 is in close contact with the liquid storage part 505, thereby reducing the vibration kinetic energy and vibration amplitude of the bellows body 1 and protecting the bellows body 1.

[0056] When the buffer 501 on the output end side is continuously squeezed, the fluid 504 flows into the buffer 501 on the input end side, causing the buffer 501 on this side to stretch, and the buffer 501 on the input end side pushes the bellows body 1 to move toward the output end, increasing the moving stroke of the bellows body 1. Therefore, when the impact force is large, the kinetic energy of the impact is converted into the movement of the bellows body 1 and the kinetic energy of the fluid 504 on the output end side discharged into the liquid storage part 505 and the buffer 501 on the input end side, which has a better buffering effect on the bellows body 1, thereby achieving better shock absorption and impact resistance.

[0057] The transmission tube 502 can bend and deform to a certain extent as the buffer 501 expands and contracts, thereby adapting to the displacement of the connection between the two ends of the transmission tube 502 and the connecting groove 503 when the buffer 501 expands and contracts, without affecting the normal use of the transmission tube 502. Through the action of the two buffers 501, the transmission tube 502 and the liquid storage part 505, the bellows body 1 is contracted to a certain extent, causing the buffer 501 to contract and expand, thereby increasing the movement stroke of the bellows body 1, thereby offsetting part of the impact force of the fluid on the bellows body 1, reducing the damage of the impact force of the fluid to the bellows body 1 and the inner protective tube 101, ensuring the stability and effectiveness of the bellows body 1 and the inner protective tube 101 during use, preventing the bellows body 1 from losing its own impact resistance and shock absorption capabilities due to excessive contraction or stretching, and extending the service life of the bellows body 1 and the application of coping with complex fluid impacts.

[0058] In summary, by setting the buffer 501 on one side of the input end, when the bellows body 1 is impacted, the bellows body 1 can overcome the resistance of the fluid 504 to pull the buffer 501 on this side to stretch, and when the input end of the bellows body 1 contacts the buffer 501, due to the viscous resistance of the fluid 504, the fluid 504 plays a shock absorbing role on the side of the bellows body 1 located at the input end. When the bellows body 1 vibrates, the fluid 504 will be driven to vibrate through the buffer 501. The larger force is required, and the viscosity of the fluid 504 is large, which can greatly reduce the vibration of the bellows body 1 on this side, thereby reducing the vibration and impact caused by the larger impact force on the input end side, protecting the bellows body 1, and when the bellows body 1 pulls the buffer 501 to stretch, the movement stroke of the bellows body 1 is increased, consuming the impact force of the fluid on the bellows body 1, thereby increasing the impact resistance and fatigue resistance of the bellows body 1. At the same time, the buffer 501 is set at the output end of the fluid, and the two buffers 501 are connected. The connecting groove 503, the transmission pipe 502, and the liquid storage part 505 are connected to each other, so that the fluid 504 in the two buffers 501 can move and exchange, so that when the bellows body 1 is subjected to a strong impact, the two buffers 501 interact with each other to offset a part of the impact force. By making the two buffers 501 interact with each other, one contracts and the other stretches, when the bellows body 1 is subjected to an impact, the stroke of the bellows body 1 is increased again, which plays a certain protective role on the bellows body 1 and can increase the bellows body. When the body 1 is impacted, the rapid contraction and movement of the bellows body 1 causes the fatigue resistance and impact resistance of the bellows body 1 to be reduced or even damaged, and the liquid storage part 505 is provided, after the buffer 501 on the output end side is compressed, the liquid flows into the liquid storage part 505, so that the liquid storage part 505 expands and contacts with the wave crest on the side of the bellows body 1 close to the input end and performs flexibly resistance, so that the vibration of the bellows body 1 is transmitted to the fluid 504 inside the liquid storage part 505, which plays a shock-absorbing role on the bellows body 1.
