Description

Technical Field

[0001] The present invention relates to a throttling structure, specifically to the assembly connection of a throttling structure. Background Art

[0002] The pipeline is equivalent to the blood vessels of an engine, enabling the connection between various engine components, accessories, between components and accessories, and between the engine and the aircraft, transporting their respective specified fluid media, and realizing functions such as engine operation, control, and manipulation. In an engine, the air pipeline is used to transport air media, mainly responsible for guiding the air flow to achieve functions such as bleeding and cooling bleed air. Since the pipe diameter is usually large, and in some functions, the pipe diameter can reach about 4 inches, a quick-release flange structure is often used to replace the conventional pipe joint as the connection method, thereby improving the assembly performance to a certain extent.

[0003] Generally, the air pipeline will be connected to a valve to achieve the purpose of quickly adjusting the air flow. However, the adjustment ability of the valve is often limited. Therefore, in actual use, the variation range of the air flow will be restricted within the adjustable range of the valve.

[0004] For example, in some usage cases, the space for installing a valve in a large-diameter air pipeline is limited, and the adjustable range of a single valve cannot meet the adjustment needs of the air flow. Therefore, after connecting the valve, an additional throttling structure needs to be added to adjust the flow cross-section to increase the adjustment range. At the same time, in order to quickly change this adjustment range within a certain range, it is often necessary to quickly, conveniently, and safely replace different throttling structures in actual use.

[0005] While meeting the usage requirements, it is also necessary not to limit the spatial pipe shape of the pipelines connected at both ends, so that the throttling structure is not limited to being applied to straight pipelines. This is somewhat difficult for conventional throttling structures. As Figure 1 shown in the common spatial pipeline pipe type, the spatial pipeline 100 generally includes a first end 101 and a second end 102. Generally, when installing, either end of the spatial pipeline 100 is first fixed to other components. For example, the first end 101 is first fixedly connected to a certain engine component. At this time, the angle and position of the second end 102 at the other end are fixed. Therefore, in the above situation, an ordinary throttling structure needs to be connected in cooperation with a specific pipe type such as a straight pipe, and cannot be freely connected to pipelines of any pipe type.

[0006] In addition, when replacing the throttling structure, it is often necessary to simultaneously remove the pipelines connected at both ends, and sometimes even remove multiple sections of pipelines to vacate enough assembly space, which increases the extra workload for the disassembly and assembly of the throttling structure. Summary of the Invention

[0007] An object of the present invention is to provide a throttling structure to achieve the free rotational installation of the throttling structure with pipelines of various shapes.

[0008] The throttling structure for achieving the above object includes a throttling element and a pair of throttling connectors. The throttling connectors include a first end portion which is arranged as a clamp connection structure; the throttling element is arranged between the pair of throttling connectors and is connected to the second end portion of the throttling connectors to form the throttling structure; wherein, the throttling connectors and the throttling element are of a rotary body structure, enabling the throttling structure to be connected to a pipeline at any angle.

[0009] In one or more embodiments, the clamp connection structure includes a first mounting flange, and a clamp is clamped on the outer peripheral surface of the first mounting flange.

[0018] Another object of the present invention is to provide a throttling pipeline, including a pipeline and the above throttling structure. The pipeline provides a connection end, and the throttling structure can be detachably connected to the connection end rotatably freely.

[0019] In one or more embodiments, the clamp connection structure includes a first mounting flange, and the connection end is a flange mating portion mating with the first mounting flange.

[0020] In one or more embodiments, the clamp connection structure includes a rolling wave structure, and the connection end is a mating end that cooperates with the rolling wave structure.

[0021] The above-mentioned throttling structure is connected to the pipeline and the throttling member respectively through the throttling connector. The detachable setting of the throttling member and the throttling connector enables the throttling member to be quickly replaced, thereby realizing rapid and effective adjustment of the air flow range; and the throttling member and the throttling connector are a rotating body structure. When the throttling connector is fixedly connected to the throttling member, it can be freely rotated and installed on the pipeline without being restricted by the pipeline space pipe shape and angle, and has good versatility and easy operation.

[0054] 200 Throttle structure Detailed implementation manners

[0055] The present invention will be further described below in conjunction with specific embodiments and the accompanying drawings. More details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can obviously be implemented in many other ways different from this description. Those skilled in the art can make similar generalizations and deductions according to the actual application situation without departing from the connotation of the present invention. Therefore, the protection scope of the present invention should not be limited by the content of this specific embodiment. It should be noted that these and subsequent other drawings are only examples, and they are not drawn under the condition of equal proportions, and should not be used to limit the actual required protection scope of the present invention.

[0056] As Figure 2 shown, the throttle structure 200 is used for throttling of the pipeline 20, and includes a throttle part 60 and a pair of throttle connecting pieces 70. The throttle part 60 is arranged between the pair of throttle connecting pieces 70.

[0057] The throttle connection member 70 includes a first end portion 40 for connecting with the pipeline 20. The first end portion 40 is arranged as a clamp connection structure and is connected with the pipeline 20 through the clamp connection structure, so that the angle and shape of one end of the pipeline 20 do not need to be considered, and it has good versatility. Moreover, the clamp structure is simple in form and compact in structure, effectively saving the installation space.

[0058] Since the throttle member 60 is arranged between a pair of throttle connection members 70, the throttle member 60 is connected with the second end portion 50 of the throttle connection member 70, and a pair of throttle connection members 70 and the throttle member 60 form the throttle structure 200. The throttle connection member 70 and the throttle member 60 are arranged as rotary body structures, which can enable the second end portion 50 of the throttle connection member 70 to be connected with the pipeline 20 at any angle. That is to say, the throttle connection member 70 and the throttle member 60 are both rotary body structures by themselves, and can still achieve fixed connection with each other after rotating at any angle and form the throttle structure 200.

[0059] Since the throttle connection member 70 and the throttle member 60 are rotary body structures and are fixed to the pipeline 20 by using a clamp structure, when the throttle structure 200 is connected with the pipeline 20, it can also be matched with the pipeline 20 at any angle, that is, the second end portion 50 connected with the pipeline 20 can also be matched with the pipeline 20 at any angle, and the limitation of the pipe type of the pipeline 20 does not need to be considered, and it is applicable to pipeline structures of any pipe type, making the throttle structure 200 have universality.

[0060] The above throttle structure 200 can be installed by freely rotating 360 degrees without restricting the spatial pipe type of the connected pipeline 20, without considering the positioning problem of the connection hole between the pipeline 20 and the throttle member in the traditional installation method, without considering the pipeline space pipe type and angle, so as to achieve the purpose of quickly, conveniently and safely adjusting the air flow, and has good versatility. The clamp 30 is preferably a quick-release clamp, and the quick-release clamp is a standard part commonly used in industry, which has good versatility, saves installation time, and also takes into account the convenience of assembly.

[0061] Continue to refer to Figures 2 to 5 As shown, the second end portion 50 of the throttle connection member 70 includes an installation connection hole 53, and the throttle member 60 includes a corresponding connection hole 61 corresponding to the installation connection hole 53. The throttle member 60 and the throttle connection member 70 are fixed by a connecting member passing through a pair of installation connection holes 53 and the corresponding connection holes 61 respectively. For example, both the installation connection hole 53 and the corresponding connection hole 61 are screw holes, and the throttle member 60 and a pair of throttle connection members 70 are fixedly connected by a bolt (not shown in the figure) passing through the installation connection hole 53 and the corresponding connection hole 61. By sequentially connecting the installation connection hole 53 - the corresponding connection hole 61 - the installation connection hole 53 with bolts, the quick disassembly connection between the throttle member 60 and the throttle connection member 70 can be realized. The number of parts is small, the structure form is simple, and it has operability.

[0062] On the basis of the above embodiments, in order to enhance the tight connection between the throttle member 60 and the throttle connection member 70, the second end portion 50 of the throttle connection member 70 further includes a sealing groove 55 for installing a throttle sealing ring 57 to ensure the airtightness between the throttle connection member 70 and the throttle member 60. In actual operation, the airtightness of the throttle structure is generally required to maintain pressure for 5 minutes under a pressure of 1 MPa without leakage of the throttle structure, which meets the requirements.

[0063] The throttle sealing ring 57 is preferably a rubber sealing ring or a metal sealing ring: if it is used in a non-high-temperature environment, the throttle sealing ring 57 is selected as an O-shaped rubber sealing ring; if it is used in a high-temperature environment, the throttle sealing ring 57 is selected as a metal sealing ring. Through the above settings, the requirements of the throttle structure in different temperature working environments can be met, so that the throttle structure 200 is applicable to both high- and low-temperature working conditions and ensures the safety of the throttling process.

[0064] In order to enable the throttle connection member 70 and the throttle member 60 to be freely connected to each other at any angle, in one embodiment of the throttle connection member 70, the mounting connection holes 53 are located on a pair of flange plates at the second end portion 50, and a plurality of mounting connection holes 53 are evenly arranged circumferentially on the flange plates. Correspondingly, the throttle member 60 provides a flange plate with a plurality of corresponding connection holes 61 corresponding to the flange plate with the mounting connection holes 53.

[0065] By arranging the mounting connection holes 53 and the corresponding connection holes 61 on the flange plates, it is satisfied that the end portions of the throttle connection member 70 and the throttle member 60 are of a rotary body structure. When connecting, the throttle connection member 70 and the throttle member 60 can be connected at any angle without considering the angle fixed at one end or the specific pipe type of the pipeline, which improves the flexibility and convenience of installation. At the same time, the appropriate connection holes and the number of connection members can be selected according to the connection strength between the two to ensure the connection strength between the throttle connection member 70 and the throttle member 60.

[0066] In another embodiment of the throttle connection member 70, referring to Figure 3 As shown, the mounting connection holes 53 are located on a plurality of symmetrically distributed lugs 51 extending from the second end portion 50. Correspondingly, the throttle member 60 provides corresponding lugs corresponding to the lugs 51 with the mounting connection holes 53, and the corresponding connection holes 61 are arranged on the corresponding lugs. By arranging the mounting connection holes 53 and the corresponding connection holes 61 on a plurality of symmetrically distributed lugs at the second end portion 50 and the throttle member 60, it is satisfied that the throttle connection member 70 and the throttle member 60 are of a rotary body structure, and the throttle connection member 70 and the throttle member 60 can also be connected at any angle to form the throttle structure 200, so that no additional positioning consideration is required and it is applicable to various pipelines.

[0067] The distribution pattern of the installation connection holes 53 includes, but is not limited to, the above embodiments. In other embodiments, as long as the installation connection holes 53 and the corresponding connection holes 61 satisfy any structure in which they can face each other at any angle and allow a connecting member to pass through, and can achieve the purpose of fixing the throttle connecting member 70 and the throttle member 60, they can be applied to the present disclosure without exceeding the scope of the present disclosure.

[0068] Based on the above embodiments, the throttle member 60 includes a plurality of throttle members with different throttle apertures, and any throttle member can be replaceably connected to the throttle connecting member 70 to quickly adjust the flow rate range. When it is necessary to change the adjustment range of the flow rate in the pipe, remove the connecting member that connects the throttle connecting member 70 and the throttle member 60, and reassemble a new throttle member 60 with a different throttle aperture between a pair of throttle connecting members 70, then the throttle flow rate of the pipeline can be adjusted according to actual requirements.

[0069] Furthermore, by setting the throttle member 60 as a standard part that meets the installation dimensions, when replacing, it is not necessary to remove the connected pipeline, and only the throttle member 60 needs to be replaced to adjust the throttle flow rate range, which is fast, convenient, saves working hours, and has good operability.

[0070] Continue to refer to Figures 2 to 6 , the first end 40 of the throttle connecting member 70 and the pipeline 20 are quickly connected through a clamp connection structure. Referring to one embodiment Figure 6 shown, the clamp connection structure includes a first mounting flange 41, and a clamp 30 is clamped on the outer peripheral surface 43 of the first mounting flange 41. Correspondingly, the pipeline 20 provides a connection end 21, and the connection end 21 is a flange mating portion that mates with the first mounting flange 41. As Figure 6 shown, during installation, the flange 44 of the first mounting flange 41 extends into the interior of the flange mating portion of the pipeline 20, and the inner peripheral surface 33 of the clamp 30 is simultaneously in contact with the outer peripheral surfaces of the first mounting flange 41 and the flange mating portion, so as to be clamped on the throttle connecting member 70 and the pipeline 20, and fix the pipeline 20 and the throttle connecting member 70.

[0071] By connecting the pipeline 20 and the throttle structure 200 through a clamp, the pipeline 20 and the throttle structure 200 can be quickly separated, and the throttle structure 200 can rotate 360° around its own axis. Therefore, the connected pipeline 20 does not need to be a straight pipe type, and at the same time, no additional positioning design and operation are required, and the installation of the throttle structure can be quickly completed.

[0072] Preferably, a first sealing ring 32 is provided between the outer peripheral surface 43 of the first mounting flange 41 and the outer peripheral surface of the connection end 21 and the clamp 30. The first sealing ring 32 ensures the connection airtightness between the throttle structure 200 and the pipeline 20, avoids gas leakage, and improves the safety of throttling.

[0073] Another embodiment of the first end portion 40 is referred to Figure 7 As shown, the clamp connection structure includes a rolling wave structure 46. The pipeline 20 includes a mating end portion 23 that mates with the rolling wave structure 46. The clamp 30 is clamped on the outer peripheral surface at the engagement portion between the mating end portion 23 and the rolling wave structure 46. By setting the first end portion 40 as the rolling wave structure 46, the corrugations of the rolling wave structure 46 can better ensure the airtight connection with the pipeline 20. While meeting the working requirements, it also further ensures the safety of the throttling structure, taking into account reliability and assembly.

[0074] An embodiment of the throttling connector 70 is as Figure 3 shown. The first end portion 40 and the second end portion 50 form an integral structure. For example, both the first end portion 40 and the second end portion 50 are flange structures. The two flange structures are connected into an integral throttling connector 70 by using a high-temperature fusion process.

[0075] By setting the throttling connector 70 as an integral structure, the relative positions of the two ends during installation can be ensured when connecting the pipelines. At the same time, the throttling connector 70 also has better airtightness, ensuring the safety of the throttling process. At the same time, the throttling connector 70 also needs to undergo flaw detection to further ensure the overall airtightness of the throttling connector 70 and avoid leakage problems.

[0076] Another embodiment of the throttling connector 70 is as Figure 7 shown. A metal bellows structure 45 is added between the first end portion 40 and the second end portion 50 for assembly position compensation, such as compensating for the positional accuracy during the assembly of large-diameter pipelines. The length between the first end portion 40 and the second end portion 50 can be increased or shortened through the metal bellows structure 45, enabling the throttling connector 70 to adjust its own length according to the actual installation environment, improving the installation flexibility of the throttling connector 70, and making the throttling structure 200 applicable to the installation of various pipelines, having versatility.

[0077] Based on the above embodiments, when the diameter of the pipeline 20 is relatively large, mounting edges can be added to both the first end portion 40 and the second end portion 50 of the throttling connector 70, providing the possibility of support for large-diameter pipeline components.

[0078] Combined with the above introduction of the throttling structure 200, a throttling pipeline can also be understood. The throttling pipeline includes the pipeline 20 and the above-mentioned throttling structure 200. The pipeline 20 provides a connection end 21, and the throttling structure 200 can be detachably connected to the connection end 21 rotatably. The above throttling pipeline separates the pipeline from the throttling structure, reducing the restriction on the pipe type while also achieving the rapid assembly of the throttling structure in the throttling pipeline.

[0079] The connection process of the throttling pipeline will be described below with reference to the accompanying drawings.

[0080] (1) Select to fixedly connect the first end 40 and the second end 50 into a throttle connector 70 through a high-temperature fusion process according to the actual working environment, or connect the first end 40 and the second end 50 into a throttle connector 70 through a metal bellows structure 45. And prepare a pair of throttle connectors 70.

[0081] (2) According to the pipeline throttling requirement, select a throttle member 60 with an appropriate throttle aperture, and select an appropriate throttle sealing ring 57 according to the temperature requirement, and connect a pair of throttle connectors 70 to the throttle member 60 respectively to form a throttle structure 200.

[0082] (3) Connect the two ends of the throttle structure 200 to two pipelines 20 with connection ends 21 respectively through clamps 30 to complete the assembly.

[0083] (4) By disassembling and assembling the clamp 30 and the connector connecting the throttle member 60 and the throttle connector 70, the required throttle member 60 can be quickly replaced to meet the requirement of flow regulation.

[0084] The above throttle pipeline realizes the quick replacement of the throttle structure in the throttle pipeline through a pair of throttle connectors, and does not need to consider the specific pipe type of the pipeline, can be freely connected to pipelines of any pipe type, and at the same time does not need to remove multiple pipelines to vacate enough assembly space, realizing convenient and safe replacement of different throttle structures in actual use and improving the actual installation efficiency.

[0085] Although the present invention is disclosed above with preferred embodiments, it is not used to limit the present invention. Any person skilled in the art can make possible changes and modifications without departing from the spirit and scope of the present invention. Therefore, any modification, equivalent change and decoration made to the above embodiments according to the technical essence of the present invention without departing from the technical solution of the present invention all fall within the protection scope defined by the claims of the present invention.
