Description

Technical Field

[0001] This utility model relates to the field of automotive component technology, specifically to an integrated pressure reducing valve bracket. Background Technology

[0002] Pressure reducing valve brackets are mainly used to fix and support pressure reducing valves, ensuring that the pressure reducing valves maintain a stable and reliable working state during fluid pressure regulation. They are generally installed on the longitudinal beams of the engine room on the right side of the engine room.

[0003] However, existing pressure-reducing valve bracket designs are relatively simple, only capable of fixing the pressure-reducing valve in place. In practical applications, components that work in conjunction with the pressure-reducing valve, such as low-pressure filters and gas leak alarm sensors, often require separate mounting structures, resulting in a dispersed layout and large space occupation for the entire fluid control system. This layout not only increases the complexity of equipment installation in the engine room, raising installation costs and maintenance difficulties, but also hinders the efficient use of engine room space, making the layout less compact. Utility Model Content

[0004] The present invention aims to provide an integrated pressure reducing valve bracket to solve the problems of limited functionality and non-compact cabin space layout of existing pressure reducing valve brackets.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an integrated pressure reducing valve bracket, comprising a pressure reducing valve mounting plate, a sensor mounting plate, and a filter mounting plate fixedly connected, wherein the sensor mounting plate is located on the back of the pressure reducing valve mounting plate and is used to install a gas leak alarm sensor, the filter mounting plate is located on the front of the pressure reducing valve mounting plate and is used to install a low-pressure filter, and the pressure reducing valve mounting plate is used to install a pressure reducing valve.

[0006] The pressure reducing valve mounting plate has a "7" shaped structure, including a first mounting surface and a second mounting surface connected by an arc transition. The second mounting surface is located below the first mounting surface and is perpendicular to the first mounting surface. The first mounting surface has at least two bracket mounting holes, and a bracket boss nut is provided at the corresponding position of the bracket mounting holes. The second mounting surface has at least one positioning center hole and at least two pressure reducing valve mounting holes. The pressure reducing valve mounting holes are located below the center hole, and matching pressure reducing valve bolts are provided in the pressure reducing valve mounting holes to fix the pressure reducing valve to the back of the second mounting surface.

[0007] The sensor mounting plate is located on the back of the second mounting surface. The sensor mounting plate is provided with at least one sensor mounting hole and a positioning hole for positioning. The sensor mounting hole is provided with a matching sensor bolt to fix the gas leak alarm sensor under the sensor mounting plate.

[0008] The filter mounting plate is located on the front side of the second mounting surface; the filter mounting plate is provided with at least two filter mounting holes, and filter boss nuts are provided at the corresponding locations of the filter mounting holes; the filter mounting holes are provided with matching filter bolts to fix the low-pressure filter on the front side of the sensor mounting plate;

[0009] The low-pressure filter is connected to the pressure reducing valve via a pressure reducing valve gas hose, which is located on the side away from the sensor mounting plate.

[0010] The principle of this solution is as follows: In practical applications, an integrated pressure reducing valve bracket is formed by the fixed connection of a pressure reducing valve mounting plate, a sensor mounting plate, and a filter mounting plate. During assembly, firstly, positioning is achieved using the corresponding structure on the pressure reducing valve via the center hole. Then, the pressure reducing valve is stably installed on the back of the pressure reducing valve mounting plate by the engagement of the pressure reducing valve bolts and the pressure reducing valve mounting holes. Next, the gas leak alarm sensor is precisely positioned by aligning it with the positioning holes on the sensor mounting plate. Then, the gas leak alarm sensor is securely installed below the sensor mounting plate by the engagement of the sensor bolts and the sensor mounting holes. Afterward, the low-pressure filter is fixedly installed on the front of the filter mounting plate by the engagement of the filter bolts, the filter mounting holes, and the filter boss nuts. Finally, the low-pressure filter is connected to the pressure reducing valve via the pressure reducing valve's gas hose and is located on the side away from the sensor mounting plate, thus completing the assembly of the entire integrated pressure reducing valve bracket.

[0011] Finally, the entire bracket is fixedly installed on the longitudinal beam of the nacelle on the right side of the nacelle by the engagement of bolts with the bracket mounting holes and bracket boss nuts.

[0012] The advantages of this solution are: (1) This solution breaks through the single-function limitation of traditional pressure reducing valve brackets, integrates the installation of pressure reducing valve, gas leak alarm sensor and low pressure filter into one, significantly improves space utilization, reduces the number of installation parts, and reduces assembly complexity and labor costs; at the same time, this integrated design makes the layout of each component compact and reasonable, effectively reduces gas system pipeline connections, reduces leakage risk, enhances system safety and stability, and facilitates unified maintenance and repair in the later stage.

[0013] (2) This solution achieves the integrated installation of multiple functional components by cleverly designing the connection methods of the pressure reducing valve mounting plate, sensor mounting plate, and filter mounting plate, as well as the corresponding positioning, mounting hole positions, and spatial layout of each component. This design not only improves the integration of the overall structure, but also facilitates the independent assembly of each component and the overall assembly, significantly improving the overall assembly efficiency.

[0014] Preferably, as an improvement, the sensor mounting plate has an inverted "7" shape structure, which includes a horizontally distributed connecting part and an outwardly inclined and bent support part, and the connecting part and the support part are connected by an arc-shaped transition.

[0015] Beneficial effects: The inverted "7" shape structure allows for a three-dimensional layout of the sensor mounting plate within a limited space, thereby optimizing the spatial arrangement and improving installation adaptability. The arc-shaped transition design between the connecting part and the supporting part avoids the stress concentration problem caused by right-angle turns, improves the mechanical performance of the overall structure, and enhances the mounting plate's resistance to bending and torsion under stress.

[0016] Preferably, as an improvement, the connecting part is connected to one side of the second mounting surface, the supporting part is in a suspended state, the inclination angle of the supporting part forms an angle of 45-80 degrees with the side of the second mounting surface, and the sensor mounting hole and the positioning hole are located on the supporting part.

[0017] Beneficial effects: The layout and design of the connecting parts and the support parts make full use of the three-dimensional space, avoid interference with other components, and improve the space utilization and layout flexibility of the overall structure. It can be firmly fixed to the pressure reducing valve mounting plate through the connecting parts, and the gas leak alarm sensor can be installed on the sensor mounting plate through the inclined support parts, thereby meeting the installation requirements.

[0018] Preferably, as an improvement, the thickness of the sensor mounting plate is 2mm-3mm, the width of the sensor mounting plate is 20mm-30mm, and the distance between the sensor mounting hole and the positioning hole is 20mm-25mm.

[0019] Beneficial effects: (1) This solution achieves a reasonable balance between structural strength and lightweight. The thickness design ensures that the sensor mounting plate has sufficient rigidity and anti-deformation ability, while avoiding excessive structural weight and meeting the requirements of lightweight design; the width design ensures installation stability and facilitates arrangement in a limited space, improving the overall compactness of the structure.

[0020] (2) The spacing design between the sensor mounting hole and the positioning hole improves versatility and can meet the installation standards of most small sensors. It enhances the adaptability of the sensor mounting plate to different models of sensors and can effectively prevent stress concentration or installation interference caused by excessive hole spacing, ensuring installation accuracy, reliability and installation speed.

[0021] Preferably, as an improvement, the distance between the support and the second mounting surface is 12mm-16mm.

[0022] Beneficial effects: The spacing design between the support and the second mounting surface provides reasonable clearance and avoids structural interference. This spacing ensures that there is sufficient clearance between the sensor or other components mounted on the support and the second mounting surface, effectively avoiding structural collisions or friction caused by assembly errors, vibration, or thermal expansion, and improving the overall system's operational stability.

[0023] Preferably, as an improvement, the spacing between adjacent bracket mounting holes is 25mm-30mm.

[0024] Beneficial effects: The spacing design between the mounting holes of adjacent brackets can effectively prevent stress concentration or installation interference caused by excessively small hole spacing, and provides good adjustment space, which can support the flexible positioning and installation of the entire bracket on nacelles of different sizes and structural forms.

[0025] Preferably, as an improvement, the two sides of the pressure reducing valve mounting plate are bent inward to form a first flange and a second flange, the filter mounting plate is located between the first flange and the second flange, one side of the filter mounting plate contacts the first flange, and the other side of the filter mounting plate contacts the second flange.

[0026] Beneficial effects: The filter mounting plate is embedded within the pressure reducing valve mounting plate, effectively utilizing the installation space and enabling the integrated layout of multiple functional components (pressure reducing valve and filter) within a limited space, thus improving the overall structural compactness. The design of the first and second flanges provides lateral restraint and side support for the filter mounting plate, achieving restraint and stable support for the filter mounting plate and preventing it from shifting or shaking during assembly or operation.

[0027] Preferably, as an improvement, the filter mounting plate has an arched structure, and the distance between the filter mounting plate and the first mounting surface is 35mm-45mm.

[0028] Beneficial effects: (1) The arched structure has good mechanical properties, which can effectively disperse the external force, improve the load-bearing capacity and bending resistance of the filter mounting plate, and avoid deformation or breakage caused by uneven force or vibration, thereby ensuring the stability of filter installation; (2) The spacing design between the filter mounting plate and the first mounting surface provides sufficient installation space for the installation of low-pressure filters.

[0029] Preferably, as an improvement, the height of the filter mounting plate above the first flange and the second flange is 10mm-15mm.

[0030] Beneficial effects: The appropriate height provides installation space for the filter boss nut and facilitates quick and accurate alignment and installation of the low-pressure filter during assembly, avoiding poor connection or sealing failure caused by misalignment. At the same time, it makes the installation position of the low-pressure filter more obvious and accessible, making it convenient for operators to perform daily inspections, filter element replacement or cleaning operations, and significantly improving the maintainability and ease of use of the equipment.

[0031] Preferably, as an improvement, the spacing between adjacent filter mounting holes is 25mm-30mm.

[0032] Beneficial effects: The spacing design between adjacent filter mounting holes allows for quick installation and positioning of low-pressure filters.

[0033] The beneficial effects of this solution are: (1) This solution abandons the traditional design of multiple independent brackets and integrates the pressure reducing valve bracket, gas leak alarm sensor bracket and low pressure filter bracket into a comprehensive installation platform, which reduces the number of installation components, thereby reducing the number of gas pipeline connections and reducing the risk of leakage.

[0034] (2) The design of the integrated pressure reducing valve bracket in this scheme achieves the integration of multiple functional components while taking into account structural strength, assembly efficiency, maintenance convenience and cost. Attached Figure Description

Detailed Implementation

[0043] The following detailed description illustrates the specific implementation method:

[0044] In this embodiment, to illustrate the structure of the integrated pressure reducing valve bracket in detail, the term "integrated pressure reducing valve bracket" will be used uniformly. Figure 4 The side facing forward is defined as the front, and the side opposite it is defined as the back.

[0045] The implementation examples are basically as follows Figure 1 , Figure 2 , Figure 3 As shown: An integrated pressure reducing valve bracket includes a pressure reducing valve mounting plate 1, a sensor mounting plate 2, and a filter mounting plate 3 that are fixedly connected; the sensor mounting plate 2 is located on the back of the pressure reducing valve mounting plate 1, and the filter mounting plate 3 is located on the front of the pressure reducing valve mounting plate 1.

[0046] The bracket can be made of Q235 material, achieving good results, especially in terms of mechanical properties, processing technology, and economy. In this embodiment, the pressure reducing valve mounting plate 1, sensor mounting plate 2, and filter mounting plate 3 are welded together to form an integrated pressure reducing valve bracket.

[0047] Specifically,

[0048] like Figure 4 , Figure 5 As shown, the pressure reducing valve mounting plate 1 is used to install the pressure reducing valve 4. The pressure reducing valve mounting plate 1 has a "7" shaped structure, including a first mounting surface 11 and a second mounting surface 12 connected by an arc. The second mounting surface 12 is located below the first mounting surface 11 and is perpendicular to the first mounting surface 11.

[0049] The first mounting surface 11 is provided with at least two bracket mounting holes 15, and a bracket boss nut 16 is provided at the corresponding position of the bracket mounting hole 15 to achieve a stable connection of the entire bracket. Matching bracket bolts are provided in the bracket mounting hole 15 to fix the bracket in the required position.

[0050] In this embodiment, two bracket mounting holes 15 are provided on the first mounting surface 11. A bracket boss nut 16 corresponding to the bracket mounting holes 15 is installed below the first mounting surface 11. The distance between adjacent bracket mounting holes 15 is 25mm-30mm. This appropriate spacing effectively prevents stress concentration or installation interference caused by excessively small hole spacing, while also providing ample adjustment space to support flexible positioning and installation of the entire bracket on nacelles of different sizes and structural forms. Specifically, in this embodiment, the distance between adjacent bracket mounting holes 15 is 28mm, and the diameter of the bracket mounting holes 15 is 18mm. This size combination balances structural strength and assembly convenience, improving the stability and adaptability of the bracket connection.

[0051] The second mounting surface 12 is provided with at least one central hole 17 for positioning and at least two pressure reducing valve mounting holes 18. The pressure reducing valve mounting holes 18 are located below the central hole 17 and are used to achieve a stable connection of the pressure reducing valve 4. Matching pressure reducing valve bolts are provided in the pressure reducing valve mounting holes 18 to fix the pressure reducing valve to the back of the second mounting surface 12.

[0052] In this embodiment, the second mounting surface 12 is provided with a central hole 17 and two pressure reducing valve mounting holes 18. The pressure reducing valve mounting holes 18 are located below the central hole 17 and are symmetrically distributed on the left and right sides of the central hole 17. The spacing between adjacent pressure reducing valve mounting holes 18 is 40mm-45mm, providing sufficient adjustment space to flexibly position and install different models of pressure reducing valves 4, improving the adaptability and versatility of the structure. Specifically, in this embodiment, the spacing between adjacent pressure reducing valve mounting holes 18 is 41mm, and the diameter of the pressure reducing valve mounting holes 18 is 14mm.

[0053] Furthermore, the two sides of the pressure-reducing valve mounting plate 1 are bent inwards to form a first flange 13 and a second flange 14, thereby improving the structural strength and stability of the pressure-reducing valve mounting plate 1 and preventing deformation due to stress during the operation of the pressure-reducing valve 4. The height of the first flange 13 and the second flange 14 is 10mm-15mm, which effectively meets the load-bearing requirements while ensuring controllable material costs. Specifically, in this embodiment, the height of both the first flange 13 and the second flange 14 is 10mm.

[0054] The sensor mounting plate 2 is used to mount the gas leak alarm sensor 5, and it is located on the back of the second mounting surface 12. Specifically, the sensor mounting plate 2 has an inverted "7" shape, which enables a three-dimensional layout of the sensor mounting plate 2, thereby optimizing the spatial layout and improving installation adaptability. The inverted "7" shape includes a horizontally distributed connecting part 21 and an outwardly inclined and bent support part 22, with an arc-shaped transition connection between the connecting part 21 and the support part 22.

[0055] The connecting part 21 is fixedly connected to one side of the second mounting surface 12, while the support part 22 is suspended. The inclination angle of the support part 22 forms an angle of 45-80 degrees with the side of the second mounting surface 12. This design not only enables the support of the sensor body but also effectively avoids interference with other components, thereby improving the space utilization and layout flexibility of the overall structure. The support part 22 is equipped with at least one sensor mounting hole 23 and at least one positioning hole 24 to facilitate accurate positioning and reliable installation of the sensor. The sensor mounting hole 23 is equipped with a matching sensor bolt to fix the gas leak alarm sensor 5 to the bottom of the sensor mounting plate 2.

[0056] In this embodiment, the thickness of the sensor mounting plate 2 is 2mm-3mm, the width is 20mm-30mm, the distance between the sensor mounting hole 23 and the positioning hole 24 is 20mm-25mm, and the distance between the support part 22 and the second mounting surface 12 is 12mm-16mm.

[0057] Specifically, in this embodiment, the support portion 22 is equipped with a sensor mounting hole 23 and a positioning hole 24. The sensor mounting plate 2 has a thickness of 2mm and a width of 20mm. The distance between the support portion 22 and the second mounting surface 12 is 14mm. The distance between the sensor mounting hole 23 and the positioning hole 24 is 20mm-25mm. The diameter of the positioning hole 24 is 14mm, and the diameter of the sensor mounting hole 23 is 18mm. By rationally designing the structural form and size of the sensor mounting plate 2, a reasonable balance between structural strength and lightweight is achieved. This not only ensures that the sensor mounting plate 2 has sufficient rigidity and resistance to deformation, but also avoids excessive structural weight, meeting the requirements of lightweight design. In addition, while ensuring installation stability, the overall structural compactness is also improved.

[0058] The filter mounting plate 3 is used to install the low-pressure filter 6, and it is located on the front of the second mounting surface 12. The filter mounting plate 3 has an arched structure, which has good mechanical properties, can effectively disperse external forces, improve the load-bearing capacity and bending resistance of the filter mounting plate 3, and avoid deformation or breakage caused by uneven stress or vibration, thereby ensuring the stability of the filter installation.

[0059] Specifically, the filter mounting plate 3 is located between the first flange 13 and the second flange 14. Both sides of the filter mounting plate 3 are in close contact with the first flange 13 and the second flange 14, respectively, achieving lateral restraint and structural support, enhancing the overall assembly stability. Simultaneously, the filter mounting plate 3 protrudes 10mm-15mm above the first flange 13 and the second flange 14, forming a positioning boss that helps improve installation accuracy and provides a degree of protection. Furthermore, the distance between the filter mounting plate 3 and the first mounting surface 11 is 35mm-45mm, providing ample installation space for the low-pressure filter 6, facilitating pipeline layout and subsequent maintenance.

[0060] The filter mounting plate 3 is provided with at least two filter mounting holes 31, and a filter boss nut is provided at the corresponding location of the filter mounting hole 31 to securely fix the low-pressure filter 6. Matching filter bolts are provided in the filter mounting holes 31 to fix the low-pressure filter 6 to the front side of the sensor mounting plate 3. In this embodiment, the filter mounting plate 3 is provided with two filter mounting holes 31, and a filter boss nut corresponding to the filter mounting holes 31 is installed on the back of the filter mounting plate 3. The distance between adjacent filter mounting holes 31 is 25mm-30mm. This spacing design can accommodate various models of low-pressure filters 6, balancing structural strength and assembly convenience.

[0061] Furthermore, the low-pressure filter 6 is connected to the pressure reducing valve 4 via a pressure reducing valve gas hose 7. The pressure reducing valve gas hose 7 is located on the side furthest from the sensor mounting plate 2.

[0062] Specific implementation process:

[0063] like Figure 6 , Figure 7 As shown, during assembly, the center hole 17 is first positioned using the corresponding structure on the pressure reducing valve 4. Then, the pressure reducing valve 4 is stably installed on the pressure reducing valve mounting plate 1 by the cooperation of the pressure reducing valve bolt and the pressure reducing valve mounting hole 18. Next, the gas leak alarm sensor 5 is precisely positioned by aligning it with the positioning hole 24 on the sensor mounting plate 2. Then, the gas leak alarm sensor 5 is firmly installed on the sensor mounting plate 2 by the cooperation of the sensor bolt and the sensor mounting hole 23. After that, the low-pressure filter 6 is fixedly installed on the filter mounting plate 3 by the cooperation of the filter bolt and the filter mounting hole 31 and the filter boss nut. At the same time, the pressure reducing valve 4 and the low-pressure filter 6 are connected by the pressure reducing valve gas hose 7, thus completing the assembly of the entire integrated pressure reducing valve 4 bracket.

[0064] Finally, the integrated pressure reducing valve bracket is fixedly installed on the longitudinal beam of the engine room on the right side of the engine room by the cooperation of the bracket bolts with the bracket mounting hole 15 and the bracket boss nut 16.

[0065] In summary, this solution overcomes the limitations of traditional pressure reducing valve brackets with only one function, integrating the pressure reducing valve 4, gas leak alarm sensor 5, and low-pressure filter 6 into a single bracket structure. This integrated design not only significantly improves space utilization and reduces the number of installation components, but also effectively reduces assembly complexity and cost. Simultaneously, this integrated design makes the layout of each component compact and structurally sound, greatly reducing the number and arrangement of gas system pipeline connections, thereby reducing potential leakage risks, enhancing system safety and operational stability, and facilitating unified maintenance and repair in the future.

[0066] Specifically, this solution achieves a three-dimensional layout and integration through the ingenious design of the connection methods of the pressure reducing valve mounting plate 1, sensor mounting plate 2, and filter mounting plate 3, as well as the corresponding structures (such as "7" type structure and reverse "7" type structure), positioning, mounting hole positions, and spatial layout of each component. This design makes full use of the internal three-dimensional space of the bracket, avoids interference with other components, and improves the overall structure's space utilization and layout flexibility. It not only enhances installation adaptability but also provides a solid foundation for rapid assembly in different application scenarios.

[0067] Therefore, this solution achieves integrated operation of multiple functional components while taking into account structural strength, assembly efficiency, maintenance convenience, and cost.

[0068] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
