Description

Technical Field

[0001] The invention belongs to the technical field of pressure converters, in particular to an adjustable pressure converter. Background Art

[0002] In the current industrial automation and pressure monitoring field, pressure transducers are key components that connect process control and measurement systems. Their performance directly affects the accuracy and reliability of the entire system. Although there are many types of pressure transducers on the market, they still face several problems and limitations, especially in terms of adaptability and sealing. These deficiencies have become the main factors restricting their widespread application.

[0003] Traditional pressure converters are often designed for specific sizes or types of pipes, and are difficult to flexibly adapt to diverse installation environments and changing pipe specifications. This requires users to re-customize or purchase new converters when replacing or upgrading equipment, increasing costs and time burdens. This in turn leads to a cumbersome installation process for pressure converters, requiring professional tools and skills, and difficult disassembly and assembly during maintenance, especially in small or inaccessible spaces. These problems are particularly prominent and reduce work efficiency.

[0004] After searching, the existing Chinese patent publication number: CN214040468U is a pressure transmitter, including a support component, a protection component and a transmitter body, the support component includes a first cover, a first sleeve, a second sleeve and a second cover, and the protection component includes a first filter, a ball plug, a retaining ring, a spring and a second filter. The pressure transmitter measures the medium pressure. When the medium hydraulic pressure is too large, the retaining ring drives the ball plug to fit the inner wall of the lower end of the second sleeve to seal, and the pressure transmitter is isolated and protected by a multi-stage hydraulic stroke sealing protection.

[0041] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present invention. However, it is apparent to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0042] Unless otherwise defined, the up, down, left, right, front, back, inside and outside directions involved in this document are based on the up, down, left, right, front, back, inside and outside directions in the figures shown in the present invention, and are explained here together.

[0044] In this embodiment, the pressure converter assembly 1 includes a converter body 2 and a connecting neck tube 22 installed at the bottom. The bottom end of the connecting neck tube 22 is connected to a connecting end 3. The bottom end of the connecting end 3 is connected to a sealing rubber bellows 9. The bottom end of the sealing rubber bellows 9 is provided with a sealing connecting tube 10 for sealing and embedding into an external pipeline. The lower part of the inner cavity of the sealing connecting tube 10 is adapted with a sealing rubber ring 24. The sealing rubber ring 24 is connected to the external pipeline interface. The converter is made of stainless steel material. The converter body 2 is designed to be streamlined, which is convenient for installation in various industrial equipment and reduces fluid resistance. The bottom of the sealing connecting tube 10 adopts a threaded connection method to ensure the sealing and stability with the external pipeline. The sealing rubber bellows 9 and the sealing rubber ring 24 are made of high temperature resistant and oil resistant synthetic rubber to ensure long-term use without leakage under high pressure environment. The sealing connecting tube 10 is connected to the external pipeline, and the sealing rubber ring 24 serves as an intermediate seal to ensure the sealing performance of the connection. The converter body 2 and the connecting neck tube 22 are responsible for receiving and converting the pressure signal from the external pipeline, realizing the accurate measurement and transmission of the pressure, and ensuring the measurement accuracy and response speed of the system. The connecting end 3 connects the converter with the external pipeline, cooperates with the sealing rubber bellows 9 and the sealing connecting tube 10 to ensure the sealing of the pressure transmission path, prevent leakage, and improve the safety of use. The combination of the connecting neck tube 22, the sealing rubber bellows 9 and the sealing connecting tube 10 forms a complete sealing system. The cooperation of the sealing rubber bellows 9 and the sealing connecting tube 10 not only ensures the sealed connection with the external pipeline, but also can absorb certain pipeline vibrations, reduce pressure fluctuations, and improve measurement stability.

[0045] In this embodiment, the adjustable support frame assembly 11 includes a support clamping plate 4 clamped on the side of the connecting neck tube 22, a support vertical plate 5 longitudinally connected to the rear end of the support clamping plate 4, and a horizontal U-shaped clamping plate 6 fixed to the bottom end of the support vertical plate 5. The support clamping plate 4 and the support vertical plate 5 are manufactured by a casting process and have good corrosion resistance after surface treatment. The U-shaped clamping plate 6 is designed in a horizontal shape, which is convenient for clamping on the external pipe required to be installed on the pressure converter. Through the clamping of the U-shaped clamping plate 6, it can provide a stable support for the debugging of the entire pressure converter.

[0046] In this embodiment, the adjustable flexion and extension connection assembly 12 includes an electric guide rail 17 fixedly mounted on the inner wall of the supporting vertical plate 5, a guide rail slide 18 slidably adapted to the electric guide rail 17, a pen-shaped cylinder 19 mounted on the surface of the guide rail slide 18, and a fixed ring 20 fixed to the free end of the pen-shaped cylinder 19. The electric guide rail 17 is driven by a servo motor to accurately control the movement of the guide rail slide 18. The pen-shaped cylinder 19 provides the necessary thrust to ensure the stability and response speed of the entire system. The fixed collar 20 uses wear-resistant material to enhance the connection strength with the sealing connecting pipe 10. Through the coordinated operation of the electric guide rail 17, the guide rail slide 18, the pen-shaped cylinder 19 and the fixed collar 20, the pressure converter is accurately positioned and adjusted in the X-axis and Z-axis directions, thereby enhancing the adaptability to changes in the pipeline position. The electric guide rail 17 drives the guide rail slide 18 to move along the Z-axis, while the pen-shaped cylinder 19 pushes the fixed collar 20 to move along the X-axis. This three-dimensional motion system enables the pressure converter to flexibly adjust its position according to actual needs, thereby improving the flexibility of installation and the scope of application.

The light rod end of the locking bolt 8 is interference-fitted with a threaded through hole 34, and the threaded through hole 34 is embedded in the bottom surface of the movable clamping plate 7. When the locking bolt 8 is tightened, the movable clamping plate 7 is driven to lift and clamp on the external pipe in the U-shaped clamping plate 6. The cooperation between the movable clamping plate 7 and the locking bolt 8 in the U-shaped clamping plate 6 realizes the adjustable clamping of the external pipe, ensuring the adaptability of pipes with different diameters.

[0051] In this embodiment, a magnet block 29 is bonded to the free end of the plug-in connecting rod 27, a magnet sheet that is magnetically attracted to the magnet block 29 is bonded to the inner wall of the plug-in hole 26, and a limiting convex head 30 is provided on the outer wall on both sides of each plug-in connecting rod 27, and a limiting groove 31 is provided on the inner wall of the plug-in hole 26 for the limiting convex head 30 to limit and engage, and the outer wall of the tail end of the support clamping plate 4 is integrally connected with an extended hollow rectangular ear plate 15, and the top end of the support vertical plate 5 passes through the extended hollow rectangular ear plate 15 and the extended hollow rectangular ear plate 15 is connected to the support vertical plate 5 through the adjusting bolt 25. The use of the limiting convex head 30 and the limiting groove 31 ensures the correct installation position of the detachable parts such as the plug-in connecting rod 27, avoids excessive insertion or falling off, and improves the safety and stability of the system.

[0052] In this embodiment, a junction box 21 is provided on the lower outer wall of the supporting vertical plate 5, the electric guide rail 17 drives the guide rail slide 18 and the pen-shaped cylinder 19 to move along the Z axis, the pen-shaped cylinder 19 drives the fixed ring 20 and the sealing connecting pipe 10 to move along the X axis, and the sealing rubber bellows 9 and the sealing connecting pipe 10 are adjusted and adapted to be installed on the external pipeline.

[0053] In this embodiment, when the locking bolt 8 drives the movable clamp plate 7 to move longitudinally, the outer wall of one side of the movable clamp plate 7 is in longitudinal sliding friction contact with the inner wall of the U-shaped clamp plate 6, and the bottom surface of the U-shaped clamp plate 6 is provided with a threaded through hole 33 adapted to be connected with the locking bolt 8.

[0054] In this embodiment, a handle 28 is fixedly connected to the outer wall of the detachable clamping head 13 .

[0055] In this embodiment, the junction box 21 has a PLC for controlling the opening and closing of each electronic device, and the PLC model can be selected according to actual needs. The junction box 21 centrally manages all electrical connections, which facilitates the inspection and maintenance of the electrical system.

[0056] Working principle:

[0057] In actual applications, when the pressure of the external pipeline changes, the pressure converter assembly 1 transmits the pressure to the inside of the converter through the sealing rubber bellows 9 and the sealing connecting pipe 10, and converts it into an electrical signal output. The user can adjust the electric guide rail 17 to drive the movement of the pen-shaped cylinder 19 through the control system to achieve adaptation to pipelines of different diameters and accurate pressure measurement. The adjustment of the locking bolt 8 can control the tightness of the movable clamp 7 to adapt to external pipelines of different sizes and ensure a good clamping effect. In addition, the design of the support buffer spring 32 increases the system's ability to absorb shocks and vibrations, and improves the overall stability and service life;

[0058] The adjustable flexion-extension connection assembly 12 is the key to achieve dynamic adjustment. The electric guide rail 17 drives the guide rail slide 19 to slide along the predetermined track through precise motor control, thereby driving the pen-shaped cylinder 19 and the fixed collar 20 to move along the X-axis, achieving rapid adaptation to pipelines at different positions. At the same time, the assembly can also adjust the position of the measuring point as needed to adapt to changes in the pressure distribution inside the pipeline. The movable clamping plate 7 can slide up and down in the U-shaped clamping plate 6 through the rotation of the locking bolt 8 to achieve the tightening or release of the external pipeline and adapt to pipeline interfaces of different diameters;

[0059] The arc-shaped elastic plastic clamping rod 16 is located on both sides of the adapter clamping notch 14 inside the supporting clamping plate 4. By utilizing its elastic characteristics and the supporting buffer spring 32 on the back, it provides appropriate clamping force when the sealing connecting pipe 10 is installed, ensuring the tight connection and sealing of the pipeline interface, and maintaining a good connection state even in a vibrating environment. The cooperation between the detachable clamping head 13 and the plug-in connecting rod 27, through the magnetic attraction of the magnet block 29 and the magnet sheet, and the precise positioning of the limiting protrusion 30 and the limiting groove 31, facilitates rapid installation and removal, and simplifies the daily maintenance and replacement process.
