[0002] A physical booster is a device that uses two liquid pipes of different diameters to change the cross-sectional area of ​​the liquid, thereby pressurizing the liquid in the smaller diameter end. In a physical booster, the two pipes of different diameters are usually connected by welding. Once connected, the form of the device is permanently fixed and lacks flexibility. Utility Model Content

[0003] In view of the technical problems existing in the background art, this application provides a physical booster, including:

[0004] A stepped booster assembly includes at least two pipe fittings, wherein at least two pipe fittings have different diameters. The input end of the larger diameter pipe fitting is plugged with a booster base, and the output end of the smaller diameter pipe fitting is plugged with a booster top plate.

[0005] Connecting components are used to connect pipe fittings of different diameters;

[0006] In the stepped pressurization pipe assembly, the smaller diameter pipe fitting is inserted into the larger diameter pipe fitting, and the connection is detachable through the connecting component.

[0007] In some embodiments, in the stepped pressurization pipe assembly, the end of the smaller diameter pipe fitting inserted into the larger diameter pipe fitting has a mounting flange protruding outward, and the radial dimension of the mounting flange is larger than the inner diameter of the smaller diameter pipe fitting body but smaller than the inner diameter of the larger diameter pipe fitting. The mounting flange is used to cooperate with the connecting assembly to realize the detachable connection of two pipe fittings with different diameters.

[0008] In some embodiments, the stepped booster pipe assembly has a mating flange protruding inward from the pipe fitting with a larger diameter. The inner diameter of the hollow part of the annular protrusion structure extending radially inward from the mating flange is larger than the diameter of the pipe fitting with a smaller diameter in the stepped booster pipe assembly. The mating flange is used to mate with the connecting assembly to achieve a detachable connection between two pipe fittings with different diameters.

[0009] In some embodiments, in the stepped booster pipe assembly, the end of the smaller diameter pipe fitting inserted into the larger diameter pipe fitting has an outwardly protruding mounting flange, and the larger diameter pipe fitting has an inwardly protruding mating flange. The radial dimension of the mounting flange is larger than the inner diameter of the smaller diameter pipe fitting but smaller than the inner diameter of the larger diameter pipe fitting. The inner diameter of the hollow portion in the center of the radially inwardly extending annular protrusion of the mating flange is larger than the diameter of the smaller diameter pipe fitting in the stepped booster pipe assembly. The mating flange and the mounting flange cooperate to complete the detachable connection between the pipe fittings.

[0010] In some embodiments, the connecting assembly includes an axial retaining pin that penetrates and connects to the mounting flange to connect two fittings in the stepped booster assembly.

[0011] In some embodiments, the connecting assembly includes an axial retaining pin that penetrates and connects the mounting flange and the mating flange to connect two pipe fittings in the stepped booster assembly.

[0012] In some embodiments, the connecting assembly includes a radial fixing pin, and correspondingly, in the stepped booster pipe assembly, the smaller diameter fitting has a fixing groove on the pipe body to accommodate the radial fixing pin.

[0013] In some embodiments, the axial fixing pin also penetrates the radial fixing pin in the axial direction.

[0014] In some embodiments, the connecting assembly further includes an axial fixing pin that penetrates the radial fixing pin and fixes the radial fixing pin to the outer wall of the larger diameter pipe in the stepped booster pipe assembly.

[0015] In some embodiments, a sealing area is provided between the mounting flange and the connecting assembly, and the sealing area is filled with sealant.

[0016] This application provides a physical booster, including a stepped booster tube assembly comprising at least two tubes, wherein at least two tubes have different diameters. The input end of the larger diameter tube is fitted with a booster base, and the output end of the smaller diameter tube is fitted with a booster top plate. Specifically, the stepped booster tube assembly includes at least two tubes with different diameters to form a stepped structure, thereby creating a gradually narrowing flow channel through the stepped change from large to small diameter, providing basic physical booster capability. Simultaneously, the input end of the larger diameter tube is fitted with a booster base, which... The inlet end of the large-diameter pipe fitting is sealed to form a closed pressurization chamber, thereby preventing leakage of internal liquid and ensuring the stability of force transmission. The outlet end of the small-diameter pipe fitting is plugged with a pressurization top plate to seal the outlet end of the small-diameter pipe fitting, maintain the high pressure state at the output end, and output the increased pressure to the external environment. The pressurization base, the stepped pressurization pipe assembly, and the pressurization top plate form a hydraulic piston device. In this hydraulic piston device, the larger pressurization base is the pressure input end, and the smaller pressurization top plate is the pressure output end. When a low-pressure fluid acts on the booster base, because the area of ​​the booster base is larger than the booster plate that sits on the smaller diameter pipe, according to Pascal's principle, force equals input pressure multiplied by cross-sectional area. When this force is transmitted to the booster plate through the incompressible fluid, since the area of ​​the booster base is larger than the cross-sectional area of ​​the booster plate, the output pressure of the booster plate will definitely be greater than the input pressure of the booster base without force loss, thus achieving pressure amplification and output. The connecting assembly is used to connect pipes of different diameters, providing mechanical fixation and sealing to ensure a stable connection between nested pipes. It also enables the disassembly and maintenance of the entire device or the replacement of pipes of different sizes, adapting to different boosting requirements. In the stepped booster pipe assembly, smaller diameter pipes are inserted into larger diameter pipes and can be detached via the connecting assembly. Specifically, the smaller diameter pipe fitting is inserted into the larger diameter pipe fitting to form a nested flow channel structure, achieving a continuous transition in pipe diameter. This reduces turbulence and energy loss at abrupt changes in pipe diameter, improving energy conversion efficiency. Furthermore, the detachable connection of the stepped booster pipe assembly via the connecting components allows for easy adjustment of the pipe diameter of each segment within the assembly. For example, in optimizing the boost ratio, a specific pipe segment can be quickly replaced. In contrast, permanent welds formed by socket welding require cutting and removal, which can damage the pipe body, and re-welding requires specialized equipment and processes, resulting in high maintenance costs and time. On the other hand, the detachable structure allows for flexible combination of multiple pipe diameters, enabling the connection of ultra-large inner diameter pipes. Socket welding is typically only used for pipes with diameters below 35 mm. Through the combination of a multi-diameter stepped booster pipe assembly and a socket-type detachable connection utilizing the connecting structure, it can be deduced that this device offers the advantages of easy maintenance and flexible structural configuration.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0033] A physical pressure booster is a device that physically increases pressure, typically installed in a hydraulic system. It uses low-pressure oil to drive a large piston, with the small piston outputting high pressure. It is commonly used in industrial applications where pressure sensitivity is critical. For example, in engineering machinery, it is used in hydraulic jacks and presses; in the transportation of high-pressure fluids, it enables the gradual increase of pressure in pipelines, overcoming resistance losses during long-distance transport; and in precise pressure control, it allows for fine-tuning of the output pressure by adjusting the pipe diameter combination ratio.

[0034] In some implementation schemes, refer to Figure 1A physical booster includes a stepped booster pipe assembly 10 and a connecting component 20. Specifically, the stepped booster pipe assembly 10 includes at least two pipe fittings, wherein at least two pipe fittings have different diameters. The input end of the larger diameter pipe fitting is plugged with a booster base 12, and the output end of the smaller diameter pipe fitting is plugged with a booster top plate 11. Specifically, the stepped booster pipe assembly 10 contains at least two pipe fittings with different diameters to form a stepped structure, thereby forming a gradually narrowing flow channel through the stepped change from a large diameter to a small diameter, providing basic physical boosting capacity. It should be noted that the pipe fitting assembly can contain pipe fittings of the same diameter, or it can include more than two pipe fittings. For example, the stepped pressurization pipe assembly 10 includes two pipe fittings, wherein the first pipe fitting has a diameter of 40 mm and the second pipe fitting has a diameter of 30 mm; for example, the stepped pressurization pipe assembly 10 includes three pipe fittings, wherein the third pipe fitting has a diameter of 40 mm, the fourth pipe fitting has a diameter of 30 mm, and the fifth pipe fitting has a diameter of 20 mm to avoid damage to the small-diameter pipe body due to excessive cross-sectional differences; for example, the stepped pressurization pipe assembly 10 includes three pipe fittings, wherein the sixth and seventh pipe fittings both have a diameter of 40 mm, and the eighth pipe fitting has a diameter of 30 mm, wherein the sixth pipe fitting is used to extend the seventh pipe fitting, thereby facilitating the layout of engineering equipment. Meanwhile, the inlet end of the large-diameter pipe fitting is plugged with a pressure-boosting base 12 to seal the inlet end of the large-diameter pipe fitting, forming a closed pressure-boosting chamber, thereby preventing leakage of internal liquid and ensuring the stability of force transmission; the outlet end of the small-diameter pipe fitting is plugged with a pressure-boosting top plate 11 to seal the outlet end of the small-diameter pipe fitting, maintain the high pressure state at the output end, and output the increased pressure to the external environment; the pressure-boosting base 12, the stepped pressure-boosting pipe assembly 10 and the pressure-boosting top plate 11 form a hydraulic piston device. In this hydraulic piston device, the larger pressure-boosting base 12 is the pressure input end, and the smaller pressure-boosting top plate 11 is the pressure output end. When a low-pressure fluid acts on the booster base 12, since the area of ​​the booster base 12 is definitely larger than the booster plate 11 that is plugged on the small-diameter pipe fitting, according to Pascal's principle, force equals input pressure multiplied by cross-sectional area. When this force is transmitted to the booster plate 11 through the incompressible fluid, since the area of ​​the booster base 12 is larger than the cross-sectional area of ​​the booster plate 11, the output pressure of the booster plate 11 will definitely be greater than the input pressure of the booster base 12 without loss of force, thereby achieving the effect of pressure amplification and output.

[0035] The connecting component 20 is used to connect pipe fittings of different diameters, providing mechanical fixation and sealing to ensure a stable connection between nested pipe fittings. This allows for the disassembly and maintenance of the entire device or the replacement of pipe fittings of different sizes, adapting to different pressurization requirements. It should be noted that the connecting component 20 can be any structure that allows for a detachable connection between a smaller diameter pipe fitting and a larger diameter pipe fitting. For example, the larger diameter pipe fitting has internal threads on its inner wall, and the smaller diameter pipe fitting has external threads on its outer wall, with the two secured by the threads. For example, a flexible rubber outer cylinder is nested inside the pipe fitting, with pre-cut multi-ring fins on the cylinder wall. An injection hole is opened on the side wall of the larger pipe fitting, connecting the annular cavity formed by the gap between the pipe fittings. The outer wall of the smaller pipe fitting has fins, and the larger pipe fitting... The inner wall has an inner convex ring. After insertion, the fins are engaged in the convex ring groove. The small tube is inserted into the large tube. The flexible outer cylinder is compressed to form folds, and the fins open radially. Epoxy resin is injected into the annular cavity through the injection hole to fill the gaps between the fins. After the resin hardens, it interlocks with the fins and is unlocked after heating. For example, the end of the small tube is connected to a three-stage stepped mandrel. The large tube is embedded with a base with an annular groove. The groove path includes an "L"-shaped locking point. The base is equipped with a circumferential spring steel ball, which is engaged in the mandrel groove to provide locking force. During connection, the small tube with the mandrel is inserted into the base until it contacts the limiting flange. The mandrel control part is rotated to make the flange slide into the end of the "L"-shaped locking groove. The steel ball springs into the mandrel groove to complete the mechanical interlock. During disassembly, the mandrel is pressed down to release the steel ball lock, and it can be pulled out by rotating in the opposite direction.

[0036] In the stepped booster pipe assembly 10, smaller diameter fittings are inserted into larger diameter fittings and detachably connected via connecting components 20. Specifically, the insertion of smaller diameter fittings into larger diameter fittings forms a nested flow channel structure, achieving a continuous transition in pipe diameter. This reduces turbulence and energy loss at abrupt changes in pipe diameter, improving energy conversion efficiency. The detachable connection of the stepped booster pipe assembly 10 via connecting components 20 allows for adjustments to the pipe diameter of each segment at any time. For example, in optimizing the boost ratio, a segment can be quickly replaced. Permanent welds formed by socket welding require cutting and removal, which can easily damage the pipe body, and re-welding requires specialized equipment and processes, resulting in high maintenance costs and long time consumption. Furthermore, the detachable structure allows for flexible combination of multiple pipe diameters, enabling the connection of ultra-large inner diameter pipes. Socket welding is typically only used for pipes with diameters below 35 mm. This device uses a stepped pressurization pipe group 10 with multiple pipe diameters and a socket-type detachable connection with a connection structure. It can be deduced that this device has the beneficial effects of easy maintenance and flexible and varied structural forms.

[0037] In some implementations, refer to Figure 2In the stepped pressurization pipe assembly 10, the end of the smaller diameter pipe fitting inserted into the larger diameter pipe fitting protrudes outward with a mounting flange 13. The mounting flange 13 at the insertion end of the smaller diameter pipe fitting is located inside the larger diameter pipe fitting, and the radial dimension of the mounting flange 13 is larger than the body of the smaller diameter pipe fitting but smaller than the inner diameter of the larger diameter pipe fitting, so that it can be confined inside the larger diameter pipe fitting. The mounting flange 13 is used to cooperate with the connecting assembly 20 to realize the detachable connection of two pipe fittings with different diameters. It should be noted that the connecting assembly 20 can include any structure that can realize the detachable connection of two pipe fittings through the mounting flange 13. For example, an inclined connecting piece is welded to the outside of the larger diameter pipe fitting, with connecting flanges at the front and rear ends. The left and right sides of the connecting piece are welded to the support base through triangular support bosses. The front side of the base has a tightening hole for overall installation and fixation. After the mounting flange 13 of the inner pipe is embedded inside the outer pipe, the outer edge of the flange and the inner wall of the connecting piece are pressed into contact by reinforcing ribs. This structure allows the smaller diameter pipe fittings and the larger diameter pipe fittings to form a nested flow channel. At the same time, the fit between the mounting flange 13 and the connecting assembly 20 not only ensures the coaxiality of the two pipe fittings to reduce turbulence loss, but also provides a detachable function to replace different pipe diameter combinations or maintain the internal flow channel, thus optimizing the pressurization efficiency and enhancing the structural adaptability.

[0038] In other embodiments, reference is made to... Figure 3In the stepped booster pipe assembly 10, a mating flange 14 protrudes inward from the larger diameter pipe fitting. It is important to note that the position of the mating flange 14 is related to the depth to which the smaller diameter pipe fitting is inserted into the larger diameter pipe fitting. For example, the mating flange 14 is located in the middle of the inner wall of the larger diameter pipe fitting; alternatively, the mating flange 14 is located 5 cm from the input end of the inner wall of the larger diameter pipe fitting. The inner diameter of the hollow portion of its radially inwardly extending annular protrusion is larger than the outer diameter of the smaller diameter pipe fitting, allowing it to pass smoothly. The mating flange 14 is used to mate with the connecting assembly 20 to achieve two pipes of different diameters. The detachable connection of the pipe fittings is achieved by the mating flange 14 cooperating with the connecting component 20 to realize the detachable connection of two pipe fittings with different diameters, thereby fixing the relative position of the two pipe fittings and forming a sealed nested flow channel. It should be noted that the connecting component 20 can include any form that can cooperate with the mating flange 14 to realize the detachable connection of the two pipes. For example, the connection structure includes a locking ring sleeved on the outside of the pipe fitting with a larger diameter and an elastic buckle fixed on the pipe fitting with a smaller diameter. The upper surface of the mating flange 14 is machined with an annular groove. After the inner pipe is inserted, the elastic buckle is engaged in the annular groove, and the locking ring is rotated to lock the elastic buckle. The flange 14 serves as the load-bearing structure inside the large-diameter pipe fitting, directly bearing the axial thrust generated by the fluid pressure. The thrust is transferred to the wall of the large-diameter pipe fitting through the detachable locking of the connecting assembly 20, preventing the small-diameter pipe fitting from coming off. At the same time, the contact surface between the inner wall of the flange 14 and the outer wall of the small-diameter pipe fitting forms a radial constraint, ensuring the coaxiality of the two pipe fittings, reducing turbulence loss and optimizing pressurization efficiency. The detachable nature of the connecting assembly 20 facilitates the replacement of different pipe diameter combinations or the maintenance of the internal flow channel.

[0039] In other embodiments, reference is made to... Figure 1 In the stepped booster pipe assembly 10, the end of the smaller diameter pipe fitting inserted into the larger diameter pipe fitting protrudes outward with an installation flange 13. The larger diameter pipe fitting protrudes inward with a mating flange 14. The mating flange 14 and the installation flange 13 cooperate to complete the detachable connection between the pipe fittings. The installation flange 13 fits against the wall of the larger diameter pipe to form a radial constraint, ensuring the coaxiality of the two pipe fittings, reducing turbulence loss and optimizing booster efficiency. The mating flange 14, as the load-bearing structure inside the larger diameter pipe fitting, directly bears the axial thrust generated by the fluid pressure. Through the detachable locking of the connecting assembly 20, the thrust is transferred to the wall of the larger diameter pipe fitting, thereby preventing the smaller diameter pipe fitting from directly bearing the axial thrust and coming out. At the same time, the nested structure of the installation flange 13 and the mating flange 14 is sealed by the fastening of the connecting assembly 20 to prevent high-pressure fluid leakage. The detachable feature of the connecting assembly 20 facilitates the replacement of different pipe diameter combinations or maintenance of the internal flow channel, enhancing structural adaptability and maintenance convenience.

[0040] In other embodiments, reference is made to... Figure 4The connecting assembly 20 includes an axial fixing pin 21. The axial fixing pin 21 penetrates and connects to the mounting flange 13 to connect two pipe fittings in the stepped booster pipe assembly 10. The mounting flange 13 provides a through-connection solid structure for the axial fixing pin 21. The axial fixing pin 21 penetrates the preset through hole of the mounting flange 13 through an interference fit or threaded locking method to form radial constraint and axial tension force, preventing small-diameter pipe fittings from coming out under fluid pressure. At the same time, the detachable fixed feature of the axial fixing pin 21 facilitates the replacement of different pipe diameter combinations or maintenance of internal flow channels.

[0041] In other embodiments, reference is made to... Figure 5 The connecting assembly 20 includes an axial fixing pin 21, which penetrates and connects the mounting flange 13 and the mating flange 14 to connect two pipe fittings in the stepped booster pipe assembly 10. The axial fixing pin 21 penetrates the pre-set through holes of the mounting flange 13 and the mating flange 14 along the axial direction of the pipe fitting, directly connecting and locking the mounting flange 13 and the mating flange 14, thereby achieving detachable axial fixing and radial constraint of the two pipe fittings, and applying a fastening force to the end face contact area of ​​the mounting flange 13 and the mating flange 14, thereby enhancing the sealing reliability of the contact surface.

[0042] In other implementations, refer to Figure 6The connecting assembly 20 includes a radial fixing pin 22. In the stepped pressurizing pipe assembly 10, the smaller diameter pipe fitting has a fixing groove 23 on its body to cooperate with the radial fixing pin 22. The radial fixing pin 22 cooperates with the fixing groove 23 on the pipe body of the smaller diameter pipe fitting. The fixing groove 23 is an annular groove or multiple circumferentially distributed notches, located on the exposed part after the smaller diameter pipe fitting is inserted into the larger diameter pipe fitting. Its depth is slightly greater than the diameter of the radial fixing pin 22 to accommodate the pin. The radial fixing pin 22 forms an axial constraint by embedding in the fixing groove 23 to prevent the smaller diameter pipe fitting from falling out of the larger diameter pipe fitting due to fluid impact or vibration, forming a composite locking mechanism to enhance the overall connection rigidity. It should be noted that the radial fixing pin 22 can either penetrate the outer wall of the large-diameter pipe fitting to achieve connection, or it can not penetrate the outer wall of the large-diameter pipe fitting and only lock into the fixing groove 23 to achieve connection. It can also be connected to the outer wall of the large-diameter pipe fitting through other connectors. For example, the radial fixing pin 22 penetrates the outer wall of the large-diameter pipe fitting that is not part of the internal liquid channel and is inserted into the fixing groove 23 to achieve fixation. For example, the radial fixing pin 22 is inserted into the fixing groove 23 and its side wall abuts against the end of the large-diameter pipe fitting to limit its movement, thereby achieving a fixing effect. For example, the radial fixing pin 22 is fixed to the end of the large-diameter pipe fitting by bolts. At the same time, the radial fixing pin 22 is inserted into the fixing groove 23. The bolt tightening force, the bolt's own shear strength, the abutting force of the part of the radial fixing pin 22 in the fixing groove 23, and the radial fixing pin 22's own shear strength work together to resist the relative displacement of the pipe fittings in the stepped pressurization pipe assembly 10.

[0043] In other implementations, refer to Figure 1 The axial fixing pin 21 also penetrates the radial fixing pin 22 in the axial direction. Specifically, the axial fixing pin 21 penetrates the central through hole of the radial fixing pin 22 in the axial direction, so that the radial fixing pin 22 is penetrated and limited by the axial fixing pin 21, thereby connecting the radial fixing pin 22 and the axial fixing pin 21 into one unit. At the same time, the radial fixing pin 22 forms a radial constraint by embedding in the fixing groove 23, directly restricting the circumferential rotation of the pipe fitting with a smaller diameter relative to the pipe fitting with a larger diameter, avoiding relative rotational displacement caused by fluid impact or vibration. In addition, the design of the axial fixing pin 21 penetrating the radial fixing pin 22 makes the radial constraint force of the radial fixing pin 22 and the axial locking force of the axial fixing pin 21 form a composite fixing structure: on the one hand, the axial fixing pin 21 presses the end face of the mounting flange 13 and the mating flange 14 through interference fit or threaded locking, transmitting the axial thrust generated by fluid pressure and achieving sealing; on the other hand, the axial fixing pin 21 locks the axial penetration of the radial fixing pin 22, preventing the radial fixing pin 22 from loosening itself along the pipe fitting axial direction, ensuring its stable engagement in the fixing groove 23.

[0044] In other implementations, refer to Figure 1 The connecting assembly 20 also includes an axial fixing pin 24, which penetrates the radial fixing pin 22 and fixes the radial fixing pin 22 to the outer wall of the larger diameter pipe fitting in the stepped booster pipe assembly 10. By directly penetrating the radial fixing pin 22 and anchoring it to the outer wall of the larger diameter pipe fitting, the axial fixing pin 24 avoids the risk of axial movement of the radial fixing pin 22 caused by high-frequency vibration or fluid impact. The single axial fixing pin 21 only provides axial restraint for the radial fixing pin 22, but cannot completely constrain its slight displacement; while the rigid fixation of the axial fixing pin 24 makes the radial fixing pin 22 and the outer wall of the pipe fitting form an integral structure, which can maintain the engagement stability of the fixing groove 23 and the radial fixing pin 22 even under extreme conditions (such as high pressure pulsation or thermal stress deformation).

[0045] In other implementations, refer to Figure 1 A sealing area 30 is provided between the mounting flange 13 and the connecting assembly 20. The sealing area 30 is filled with sealant. The sealant fills the sealing area 30 between the mounting flange 13 and the axial fixing pin 21, forming an elastic sealing layer to seal the leakage path of high-pressure fluid along the gap between the axial fixing pin 21 and the hole wall of the mounting flange 13 as much as possible. The elastic properties of the sealant (such as silicone or fluororubber) can absorb the micro-vibration energy between the axial fixing pin 21 and the pipe fitting, reducing the risk of loosening of the connecting assembly 20 due to high-frequency vibration. The sealant and the axial fixing pin 21 form a composite locking mechanism: the axial fixing pin 21 provides rigid constraint to resist fluid thrust, while the sealant fills its peripheral gap and penetrates into the micro-pits on the surface of the mounting flange 13, enhancing the adhesion between the pin and the pipe fitting.

[0046] It should be noted that this application is not limited to the above-described embodiments. The above embodiments are merely examples, and any embodiments with the same structure and effect as the technical concept within the scope of this application are included in the technical scope of this application. Furthermore, various modifications that can be conceived by those skilled in the art to the embodiments, and other ways of constructing by combining some of the constituent elements of the embodiments, without departing from the spirit of this application, are also included in the scope of this application.
