Technical Field

[0001] This invention belongs to the field of water supply pipeline technology, and particularly relates to a bidirectional stable water supply connection device. Background Technology

[0002] During pipeline water transportation, the pressure inside the pipeline will fluctuate due to factors such as the layout of the water supply network, fluid characteristics, water supply volume, and sudden changes in flow velocity. Due to the instability of this pressure, it may affect the corresponding secondary water supply equipment in some cases. Furthermore, such sudden pressure changes may damage the pipeline system and cause loosening and leakage at the pipeline connections. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned technical problems by providing a water supply connection device that is simple in structure, easy to install, and can integrate fluctuations within the pipeline to ensure overall pipeline stability.

[0004] In view of this, the present invention provides a bidirectional stable water supply connection device, comprising: Two end connectors, including a connecting pipe and end flanges at both ends of the connecting pipe for connection; The middle balancing component is located between the two end connectors and includes a balancing pipe and balancing flanges located at both ends of the balancing pipe for connection with the end flanges. Two end balance connecting blocks are respectively set at both ends inside the balance pipe and abut against the end flanges of the end connectors; A corrugated bearing pipe connects two end balance connecting blocks, and the end balance connecting blocks are connected to the end connectors at their respective ends through the corrugated bearing pipe; the corrugated bearing pipe includes a corrugated section and receiving flanges at both ends, and the receiving flanges of the corrugated bearing pipe are fixed to the outer end face of the end balance connecting block at its respective end. The central support component, located inside the balance tube, supports the two end balance connecting blocks and resets them when the two end balance connecting blocks shift or float.

[0005] In the above technical solution, the end-balanced connecting block further includes: The balance block has a frustum-shaped outer wall, with the smaller diameter end facing the middle of the balance tube. The central connecting hole is coaxially set in the middle of the balance block, and a groove is formed at the end of the limit corrugated bearing pipe near the large diameter end of the balance block. The outer floating part is spherical and is formed on the outer wall of the large diameter end of the balance block; The internal floating hole is spherical and is formed at the end of the central connecting hole near the large diameter of the balance block. The diameter of the central connecting hole is smaller than that of the connecting pipe; a protruding spherical support block that mates with the inner floating hole is formed on the end flange that abuts against the end balance connecting block; the end balance connecting block is sealed to the end flange through the inner floating hole; the end balance connecting block is sealed to the inner wall of the balance pipe through the outer floating part; when the end balance connecting block fluctuates in the water supply pipeline, it will undergo axial displacement and / or spherical oscillation.

[0006] In the above technical solution, the central support component further includes: Several support petals are evenly distributed circumferentially inside the balance tube, and their two ends abut against the end balance connecting blocks at their respective ends.

One end of the positioning bolt is embedded in the end balance connecting block, and the other end extends out of the end balance connecting block and is fixedly connected to the end of the support petal by fasteners. The retainer is set inside the balance tube and limits the support petals, positioning the middle of several support petals; When fluctuations occur in the water supply pipeline, the end balance connecting block will undergo axial displacement, thereby squeezing the support petal and causing it to deform. At the same time, the end balance connecting block will be reset under the support of the support petal.

[0007] In the above technical solution, the support lobe further includes: Two support plates, in the form of sheet-like structures, are located at both ends of the support petal and abut against the end face of the end balance connecting block at the same end. The support petal is fixedly connected to the positioning bolt through the support plates. The two connecting parts are connected to the support plate at one end, and both extend at an incline toward the middle of the inner wall of the balance tube. The arc-shaped support has an arc-shaped structure with the apex facing the inner wall of the balance tube, and connects the two connecting parts, and deforms when subjected to compression; The positioning groove passes through the connection between the arc-shaped support and the two end connecting parts, and its orthographic projection is a long groove shape; The retainer engages with the positioning groove to position and retain the support piece.

[0008] In the above technical solution, the retaining element further includes: Several retaining rods are provided on each support petal.

Several connecting pieces are integrally formed with the inner side of the outer retaining ring at one end, and connected to the connecting post of the retaining rod at the other end by fasteners.

[0009] Furthermore, the above technical solution also includes: Several floating support components are evenly distributed around the outer edge of the two balance blocks and support the end balance connecting blocks. They are corrected in time when the end balance connecting blocks shift. The floating support components include: The floating support block abuts against the outer wall of the conical surface of the balance block, and will undergo radial displacement after being squeezed against the outer wall of the balance block; The floating support assembly is installed on the wall of the balance pipe to support the floating support block, allowing the floating support block to move radially while preventing axial displacement of the floating support block.

[0010] In the above technical solution, the floating support block further includes: The floating block, when projected orthographically, has a fan-shaped structure. The inner extrusion section is formed on the side wall of the floating block, is conical in shape, and can be pressed against the outer wall of the balance block. The outer cutting section has a conical structure similar to the inner extrusion section, but the taper of the conical surface is smaller than that of the inner extrusion section; Two support springs are symmetrically arranged on both sides of the floating block, with one end abutting against the floating block and the other end abutting against the inner wall of the balance tube. The outer wall of the floating block and the inner wall of the balance tube are both formed with positioning grooves for positioning the support springs; the floating support assembly is connected to the middle of the floating block, that is, it is located between the two support springs.

[0011] In the above technical solution, the floating support further includes: The sealing cap has a connecting hole on the outer wall of the balance tube that communicates with the inside of the balance tube. The connecting hole is located on the outer wall of the balance tube and forms an installation surface. The sealing cap is fixed on the installation surface. The connecting rod has a long groove-shaped limiting hole on the sealing cover. The connecting rod is slidably set on the connecting hole, and one end can extend out of the sealing cover through the limiting hole, while the other end is fixedly connected to the floating block. A floating positioning block is installed on the sealing cover and connected to the end of the connecting rod near the sealing cover, preventing the connecting rod at that end from disengaging from the connecting hole; The floating support is located outside the sealing cover and supports the floating positioning block.

[0012] In the above technical solution, the floating support component further includes: The floating support cylinder has an installation groove formed at the upper end of the sealing cover that connects to the connecting hole, and the floating support cylinder is threadedly connected to the installation groove; A floating plug is installed inside a floating support cylinder and can be lifted by a floating positioning block. The lower outer wall of the floating plug has a sealing cone, and the upper outer wall has several sealing grooves with sealing rings inside the sealing grooves. A floating positioning spring is installed inside the floating support cylinder, with one end abutting against the end of the floating plug; The floating support cylinder has a stepped hole formed by connecting the lower hole and the upper hole. The lower hole is connected to the bottom of the mounting groove. The sealing cone of the floating plug abuts against the connection between the upper hole and the lower hole.

[0013] In the above technical solution, the floating support component further includes: The upper adjusting cap is threaded onto the upper hole of the floating support cylinder and can be adjusted to the depth of screwing into the upper hole. The other end of the floating positioning spring abuts against the end of the upper adjusting cap. The floating positioning rod is inserted into the floating support cylinder through the upper adjusting cap and is fixedly connected to the end of the floating plug inside the floating support cylinder. The part of the floating support rod located outside the upper adjusting cap forms a balance blind hole at the other end, and a balance through hole communicating with the balance blind hole is provided on the side wall of the floating positioning rod located inside the floating support cylinder.

[0014] The beneficial effects of this invention are as follows: 1. The water supply connection device, through the installation of a corrugated bearing pipe, can offset stress and mitigate some pressure fluctuations in the pipeline due to temperature changes or vibration displacement through the elastic deformation of the corrugated pipe. 2. The two end balance connecting blocks are used to achieve bidirectional integration and cancellation. At the same time, when the end balance connecting blocks have axial displacement, they will also compress the corrugated bearing pipe to better ensure the stability of the pressure inside the pipeline.

Detailed Implementation

[0016] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0017] Example 1: This embodiment provides a bidirectional stable water supply connection device, including: Two end connectors, including a connecting pipe 1 and end flanges 2 disposed at both ends of the connecting pipe 1 for connection; The middle balancing component is located between the two end connectors and includes a balancing pipe 3 and balancing flanges 4 located at both ends of the balancing pipe 3 for connection with the end flanges 2. Two end balance connecting blocks 5 are respectively set at both ends inside the balance pipe 3 and abut against the end flange 2 of the end connector; A corrugated bearing pipe 6 connects two end balance connecting blocks 5, and the end balance connecting blocks 5 are connected to the end connector at the corresponding end through the corrugated bearing pipe 6; the corrugated bearing pipe 6 includes a corrugated part and receiving flanges at both ends, and the receiving flanges of the corrugated bearing pipe 6 are fixed to the outer end face of the end balance connecting block 5 at the corresponding end. The central support component, located inside the balance tube 3, supports the two end balance connecting blocks 5 and resets them when the two end balance connecting blocks 5 shift or float.

[0018] In this embodiment, the water supply connection device can be used alone or in series; the device is placed at the connection of the pipeline to mitigate fluctuations generated within the pipeline.

[0019] The connecting device is connected to the connection points of the two pipes through the end flanges 2 on the outer side of the two end connectors. The diameters of the end flanges 2 on the outer side of the two end connectors and the corresponding pipe diameters of the connecting pipes 1 can be equal or unequal. Furthermore, the two end flanges 2 on opposite sides of the two end connectors can be connected to the central balance pipe 3, ensuring the convenience of the overall assembly of the device and the speed of the device construction and installation.

[0020] The balance pipe 3 of the middle balance component serves as the main structure for installing the voltage stabilizing component in the device. It is then connected to the end connectors via the balance flanges 4 at both ends of the balance pipe 3, which facilitates the installation and fixation of the middle balance component.

[0021] The corrugated connector 6 is installed inside the pipeline to offset stress and absorb some pressure fluctuations due to temperature changes or vibration displacement. This prevents the water supply pipeline from rupturing or the connection from loosening. The end connector, the middle balancing component, and the corrugated connector 6 are all made of metal.

[0022] The end-balancing connector 5 is made of sealing materials such as hard rubber or silicone. The end-balancing connector 5, when pressure fluctuations occur in the pipeline, further compensates and integrates these fluctuations through its floating motion, thus ensuring the water supply connection device effectively manages pressure fluctuations within the pipeline. Simultaneously, the two end-balancing connectors 5, positioned opposite each other, enable bidirectional compensation and cancellation. Furthermore, axial displacement of the end-balancing connector 5 compresses the corrugated pipe 6, further stabilizing the pressure within the pipeline. The water supply connection device, through the end-balancing connector 5 and the corrugated pipe 6, seals the water supply at both ends of the pipeline, ensuring a secure seal during pipeline transport.

[0023] The central support assembly is used to support the end balance connecting block 5 and the corrugated bearing pipe 6. When the end balance connecting block and / or the corrugated bearing pipe 6 are displaced or squeezed, they are reset in time, so as to play a good role in the next pressure fluctuation.

[0024] Example 2: This embodiment provides a bidirectional stable water supply connection device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0025] End balance connecting block 5 includes: The balance block 5a has a frustoconical outer wall, with the smaller diameter end facing the middle of the balance tube 3. The central connecting hole 5b is coaxially set in the middle of the balance block 5a, and a groove is formed at the end of the limit corrugated bearing pipe 6 near the large diameter end of the balance block 5a. The outer floating part 5c is spherical and is formed on the outer wall of the large diameter end of the balance block 5a; The inner floating hole 5d is spherical and is formed at the end of the central connecting hole 5b near the large diameter of the balance block 5a. The diameter of the central connecting hole 5b is smaller than that of the connecting pipe 1; a protruding spherical support block 2a that mates with the inner floating hole 5d is formed on the end flange 2 that abuts against the end balance connecting block 5; the end balance connecting block 5 is sealed to the end flange 2 through the inner floating hole 5d; the end balance connecting block 5 is sealed to the inner wall of the balance pipe 3 through the outer floating part 5c; when the end balance connecting block 5 fluctuates in the water supply pipeline, it will undergo axial displacement and / or spherical oscillation.

[0026] In this embodiment, the balance block 5a blocks the port of the connecting pipe 1 at the end of the end flange 2, so that water can only pass through the central connecting hole 5b in the middle of the balance block 5a; while the end of the balance block 5a abuts against the end flange 2, and the diameter of the central connecting hole 5b is smaller than the diameter of the connecting pipe 1, so that the fluctuations generated in the pipe at the end can be transmitted to the balance block 5a, and are offset and combined by the floating or displacement of the balance block 5a at that end.

[0027] The receiving flange of the corrugated receiving pipe 6 is fixed to the countersunk groove at the end of the central connecting hole 5b by bolts and other fasteners.

[0028] The outer floating part 5c is spherical and contacts the inner wall of the balance tube 3, thus ensuring the stability and sealing effect of the connection between the end balance connecting block 5 and the balance tube 3 even when the end balance connecting block 5 experiences axial displacement or spherical oscillation due to pressure fluctuations or vibrations. A sealing groove can be provided on the outer floating part 5c, and a sealing ring can be installed on the sealing groove.

[0029] The inner floating hole 5d and the spherical support block 2a on the end flange 2 can ensure good sealing contact with the connecting pipe 1 when the end balance connecting block 5 swings, and at the same time ensure smooth swing of the end balance connecting block 5, thus better integrating the fluctuations.

[0030] Example 3: This embodiment provides a bidirectional stable water supply connection device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0031] The central support components include: Several support petals 7 are evenly distributed in the circumference of the balance tube 3, and their two ends abut against the end balance connecting block 5 at their respective ends. Several positioning bolts 8 are provided on the end face of each end balance connecting block 5 that abuts against the support petal 7. Several positioning bolts 8 are evenly distributed in a circle. One end of the positioning bolt 8 is embedded in the end balance connecting block 5, and the other end extends out of the end balance connecting block 5 and is fixedly connected to the end of the support petal 7 by fasteners. The retainer is set inside the balance tube 3 and limits the support petals 7, and positions the middle part of several support petals 7; When fluctuations occur in the water supply pipe, the end balance connecting block 5 will undergo axial displacement, thereby squeezing the support petal 7 and causing the support petal 7 to deform. At the same time, the end balance connecting block 5 will be reset under the support of the support petal 7.

[0032] In this embodiment, the support petals 7 are made of elastic metal, such as spring steel sheets. Supported between the two end balance connecting blocks 5 by a plurality of support petals 7, the end balance connecting blocks 5 on either side are better reset after displacement. Simultaneously, the support petals 7 also ensure that the end balance connecting blocks 5 at both ends are sealed against the end flange 2.

[0033] One end of the positioning bolt 8 is integrally formed on the end balance connecting block 5, thereby ensuring the fixing strength of the positioning bolt 8. The support petal 7 at the same end is connected through the positioning bolt 8, thereby ensuring the installation strength of the support petal 7.

[0034] The retaining element can properly position each support petal 7, ensuring that the center of each support petal 7 is always kept at a fixed distance, and preventing excessive displacement or compression of the support petals 7.

[0035] Example 4: This embodiment provides a bidirectional stable water supply connection device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0036] Supporting lobe 7 includes: Two support plates 7a, in the form of plates, are located at both ends of the support petal 7 and abut against the end face of the end balance connecting block 5 at the same end. The support petal 7 is fixedly connected to the positioning bolt 8 through the support plates 7a. The two connecting parts 7b are respectively connected to the support piece 7a at one end, and both extend inclined towards the middle of the inner wall of the balance tube 3. The arc-shaped support 7c has an arc-shaped structure with the apex facing the inner wall of the balance tube 3, and connects the two connecting parts 7b, and deforms when compressed; The positioning groove 7d passes through the connection between the arc-shaped support part 7c and the two end connecting parts 7b, and its orthographic projection is a long groove shape; The retainer engages with the positioning groove 7d to position and retain the support piece 7a.

[0037] In this embodiment, the support piece 7a provides a good fixing point for the installation of the support petal 7, ensuring the structural stability of the support petal 7 after installation. The combined cooperation of the inclined connecting part 7b and the arc-shaped support part 7c gives the support petal 7 a good anti-compression effect, thereby ensuring that the end balance connecting block 5 can play a good floating and displacement effect, and allowing the end balance connecting block 5 to be reset better.

[0038] The positioning groove 7d is designed to cooperate with the retainer. By having the retainer pass through the positioning groove 7d, the extent to which the support petal 7 is compressed is limited, thereby allowing the support petal 7 to provide better support.

[0039] Example 5: This embodiment provides a bidirectional stable water supply connection device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0040] The retainer includes: Several retaining rods 9 are provided on each support petal 7. The middle part of the retaining rod 9 is a long groove structure that slides with the positioning groove 7d, and the two ends are threaded connecting posts. Two outer retainers are set inside the balance tube 3 and fit into the inner wall of the balance tube 3, and each outer retainer is connected to a connecting post at the same end of several retaining rods 9; The outer cage includes: The outer retaining ring 10 has a ring-column structure and slides in fit with the inner wall of the balance tube 3; Several connecting pieces 11 are integrally formed with the inner side of the outer retaining ring 10 at one end, and connected to the connecting post of the retaining rod 9 at the other end by fasteners.

[0041] In this embodiment, the middle part of the retaining rod 9 has a long groove-shaped structure that slides with the positioning groove 7d, allowing the retaining rod 9 to slide axially and vertically on the positioning groove 7d, but preventing the retaining rod 9 from rotating on the positioning groove 7d. The retaining rod 9 supports the support petal 7, preventing the support petal 7 from undergoing excessive deformation.

[0042] The outer retainer supports the retaining rod 9, so that the retaining rod 9 is normally located in the middle of the positioning groove 7d, thereby giving the support petal 7 good support and deformation capabilities.

[0043] The outer retaining ring 10 in the retainer allows the support frame to be stably held in the balance tube 3; while the end of the retaining rod 9 is positioned by the connecting piece 11 so that the retaining rod 9 will not slide on the positioning groove 7d under normal conditions.

[0044] Example 6: This embodiment provides a bidirectional stable water supply connection device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0045] Also includes: Several floating support components are evenly distributed around the outer edge of the two balance blocks 5a and support the end balance connecting block 5. When the end balance connecting block 5 deviates, it is corrected in time. The floating support components include: The floating support block 12 abuts against the outer wall of the conical surface of the balance block 5a, and will undergo radial displacement after being squeezed against the outer wall of the balance block 5a; The floating support assembly is installed on the wall of the balance pipe 3 to support the floating support block 12, allowing the floating support block 12 to move radially while preventing axial displacement of the floating support block 12.

[0046] In this embodiment, the floating support assembly mainly supports the end balance connecting block 5 when it swings and allows it to return to its original position; it also supports the end balance connecting block 5 when it undergoes axial displacement and allows it to return to its original position.

[0047] The floating support block 12 in the floating support assembly acts as a triggering component that contacts the end balance connecting block 5. When the end balance connecting block 5 is subjected to vibration or pressure fluctuations and swings or displaces, it will squeeze the floating support block 12, causing the floating support block 12 to drive the floating support assembly to move, thereby better integrating the fluctuations and allowing the end balance connecting block 5 to reset better.

[0048] Example 7: This embodiment provides a bidirectional stable water supply connection device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0049] Floating support block 12 includes: Floating block 12a has a fan-shaped structure when projected orthogonally. The inner extrusion section 12b is formed on the side wall of the floating block 12a, is conical in shape, and can be pressed against the outer wall of the balance block 5a. The outer cutting part 12c has a conical surface structure similar to that of the inner extrusion part 12b, and the taper of the conical surface is smaller than that of the inner extrusion part 12b. Two support springs 12d are symmetrically arranged on both sides of the floating block 12a, with one end abutting against the floating block 12a and the other end abutting against the inner wall of the balance tube 3. The outer wall of the floating block 12a and the inner wall of the balance tube 3 are both formed with positioning grooves 7d for positioning the support springs 12d; the floating support assembly is connected to the middle of the floating block 12a, that is, it is located between the two support springs 12d.

[0050] In this embodiment, the central angle of the orthographic projection sector of the floating block 12a is between 80 and 100°. The end balance connecting block 5 at one end is supported by three triangularly distributed sector floating support blocks 12, which maintains the stability of the support for the end balance connecting block 5 and better transmits the impact force generated by the fluctuation to the floating support block 12 when the end balance connecting block 5 swings or shifts.

[0051] The inner extrusion part 12b is designed to directly contact the outer wall of the end balance connecting block 5. It is inclined so that when the end balance connecting block 5 is displaced or swayed, it will promptly trigger and extrude the floating block 12a at the corresponding position.

[0052] The outer cutting part 12c can increase the gap between the floating support block 12 and the inner wall of the balance tube 3, ensuring the space for the floating support block 12 to move. Then, the two sides of the floating support block 12 are supported by two support springs 12d, so that the floating support block 12 can move elastically when it is squeezed, so as to better integrate the fluctuation; at the same time, it is convenient for the floating support block 12 to reset.

[0053] The positioning groove 7d prevents the support spring 12d from detaching, ensuring the stability of the structure after the support spring 12d is installed.

[0054] Example 8: This embodiment provides a bidirectional stable water supply connection device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0055] Floating support components include: The sealing cap 13 has a connecting hole on the outer wall of the balance tube 3 that communicates with the inside of the balance tube 3. The connecting hole is located on the outer wall of the balance tube 3 and forms an installation plane. The sealing cap 13 is fixed on the installation plane. The connecting rod 14 and the sealing cover 13 have long groove-shaped limiting holes. The connecting rod 14 is slidably disposed on the connecting hole, and one end can extend out of the sealing cover 13 through the limiting hole, while the other end is fixedly connected to the floating block 12a. A floating positioning block 15 is set on the sealing cover 13 and connected to one end of the connecting rod 14 near the sealing cover 13, and prevents the connecting rod 14 at the same end from disengaging from the communicating hole. A floating support is installed outside the sealing cover 13 and supports the floating positioning block 15.

[0056] In this embodiment, the sealing cap 13 is configured as a floating support to provide an installation position, while also sealing the connecting holes on the outer wall of the balance pipe. The sealing cap 13 can be detachably fixed to the mounting plane of the balance pipe 3 by fasteners such as bolts.

[0057] The connecting rod 14 is used to connect with the floating block 12a, transmit the force generated on the floating block 12a, and convert the irregular force into a force perpendicular to the sealing cover 13. This allows the floating block 12a to move radially away from the end balance connecting block 5 when it is squeezed. At the same time, the sealing cover 13 has a long groove-shaped limiting hole, and the connecting rod 14 is slidably disposed on the connecting hole, thereby preventing the floating block 12a from rotating and thus preventing it from contacting the support end balance connecting block 5.

[0058] The floating positioning block 15 is used to connect with the connecting rod 14, mainly to restrict the connecting rod 14 from the floating block 12a and prevent the floating block 12a from detaching.

[0059] The floating support component is set to buffer and support the floating positioning block 15 when it moves upward, thereby further ensuring the effect of comprehensive fluctuation.

[0060] Example 9: This embodiment provides a bidirectional stable water supply connection device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0061] Floating support components include: The floating support cylinder 16 has an installation groove formed at the upper end of the sealing cover 13 that connects to the communicating hole, and the floating support cylinder 16 is threadedly connected to the installation groove. The floating plug 17 is disposed inside the floating support cylinder 16 and can be lifted by the floating positioning block 15. The lower outer wall of the floating plug 17 forms a sealing cone, and the upper outer wall has several sealing grooves with sealing rings inside the sealing grooves. A floating positioning spring 18 is disposed inside the floating support cylinder 16, with one end abutting against the end of the floating plug 17; The floating support cylinder 16 has a stepped hole formed by connecting the lower hole and the upper hole. The lower hole is connected to the bottom of the mounting groove. The sealing cone of the floating plug 17 abuts against the connection between the upper hole and the lower hole. The mounting groove is provided with several evenly distributed receiving holes that are connected to the inside of the balance tube 3 at the location of the connecting hole.

[0062] In this embodiment, the floating support cylinder 16 is used to form a buffer chamber on the sealing cover 13. The floating plug 17 is set in the buffer chamber. When the connecting rod 14 is moved by the floating block 12a, it will squeeze the floating plug 17 through the floating positioning block 15. The floating plug 17 is supported by the floating positioning spring 18 and performs spring floating buffer, thereby achieving the effect of comprehensive fluctuation.

[0063] A pressure zone is formed on the inner wall of the balance tube 3, between the two end balance connecting blocks 5 and the corrugated receiving tube 6. A pressure gauge is installed outside the balance tube 3 to monitor the pressure zone. During use, a certain amount of pressurized gas can be injected into the pressure zone to form a buffer zone with a certain pressure on the inner wall of the balance tube 3, thereby better integrating vibration and wave. The lower hole in the floating support cylinder 16 is connected to the inside of the balance tube 3. When the connecting rod 14 moves the floating plug 17, the pressurized gas will squeeze the floating plug 17, further moving the floating plug 17 to the port of the upper hole.

[0064] Example 10: This embodiment provides a bidirectional stable water supply connection device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0065] Floating support components also include: The upper adjusting cap 19 is threadedly connected to the upper hole of the floating support cylinder 16 and can be adjusted to the depth of screwing into the upper hole.
