Description

Technical Field

[0001] The utility model belongs to the field of civil aircraft test and flight test, and specifically relates to a sensor nozzle and pipeline component. Background Art

[0002] In the development process of civil aircraft, a large number of tests are usually required to verify the functions and performance of various aircraft systems. When conducting flight tests such as fuel, inerting, and environmental control systems, it is often necessary to install sensors on the fuel or air supply pipelines to measure the fluid temperature, pressure, flow and other parameters inside the pipelines. In order to install sensors on the pipelines, it is necessary to have a nozzle on the pipeline that can cooperate with the sensor installation interface so that the sensor can sense the fluid parameters inside the pipeline through the nozzle.

[0003] At present, it is common practice to modify the design of the pipeline and weld the sensor nozzle on the pipeline. The pipeline with the sensor nozzle welded needs to be disassembled after the aircraft completes the flight test and the original pipeline installation is restored. However, different flight test subjects have different requirements for test parameters. The type and model of sensors may need to be replaced during the test of the same flight test subject. For pipelines with bends, the modification space is limited and the measurement parameter requirements may be more. In these scenarios, new pipelines are often the only option to meet different test requirements. The modified pipelines with welded sensor nozzles have a low reuse rate, the cost of multiple modifications is high, and the implementation cycle is long, which sometimes seriously affects the project progress.

[0004] In order to solve the problem of low reuse rate of pipelines welded with sensor nozzles, a sensor base has been proposed. This base can be detachably matched with the opening added to the pipeline without being welded to the pipeline, and is sealed with a sealing ring. However, in this design, the sealing form between the sealing ring and the pipeline is a single-layer sealing form in which the sealing ring fits the cylindrical surface of the pipeline opening, which has high requirements on the size of the pipeline opening. If the size of the pipeline opening is too large, the sealing effect is not good; if the size of the pipeline opening is too small, the sealing ring is easily cut by the pipe wall. In addition, for pipelines whose internal fluid is flammable liquid or hazardous gas, the reliability of the single-layer sealing form is insufficient.

[0005] Therefore, how to design a detachable pipeline modification form that can be reliably sealed, adapt to multiple interfaces, and switch quickly has become a technical problem that needs to be solved urgently. Utility Model Content

[0006] In order to solve the problem of insufficient sealing of the existing detachable sensor interface, the utility model designs a sensor nozzle and pipeline assembly, which uses a detachable double-sealed pipeline sensor nozzle and pipeline to achieve reliable sealing. In addition, the sensor nozzle and pipeline assembly of the utility model can also replace the sensor nozzle to meet the installation requirements of sensors with different interfaces without replacing the modified pipeline, so that the modified pipeline can be reused, reducing costs and increasing efficiency.

[0007] Specifically, a sensor nozzle and pipeline assembly includes a pipeline and a sensor nozzle, wherein the pipeline is provided with a pipeline opening leading to the interior, and the sensor nozzle includes: a nozzle part, wherein the nozzle opening of the nozzle part is aligned with the pipeline opening of the pipeline, thereby communicating with the interior of the pipeline, and is used for allowing the sensor to pass through the nozzle opening and the pipeline opening and be inserted into the interior of the pipeline; a main body part, which is used to detachably mount the sensor nozzle to the pipeline; and a boss, which extends through the pipeline opening to the interior of the pipeline, wherein the sensor nozzle and pipeline assembly also includes a first seal and a second seal, the first seal is arranged around the boss, and the second seal is arranged around the pipeline.

[0008] In a preferred embodiment of the utility model, the first sealing member is arranged between the outer surface of the pipeline and the inner surface of the main body, so that the first sealing member can be directly clamped between the sensor nozzle and the pipeline to achieve a sealing effect without requiring the size of the pipeline opening.

[0009] In a preferred embodiment of the utility model, the pipeline has a sealing groove formed around the outer surface of the pipeline, and the second sealing member is installed in the sealing groove. The second sealing member provides a second seal, which can more effectively prevent leakage of dangerous fluids such as fuel.

[0010] In one embodiment, a sealing groove is formed around the pipeline on both sides of the pipeline opening.

[0011] The main body includes a first ring, a second ring, a pin and a fastener, wherein the first ring and the second ring are rotatably connected by the pin, and the sensor nozzle is detachably mounted to the pipeline by the fastener. Therefore, the sensor nozzle can be conveniently mounted or dismounted by only engaging or unscrewing the first ring and the second ring by the pin.

[0012] In an embodiment of the present invention, the fastener is a clamp, which is tightened or loosened around the outer surface of the main body portion to install the sensor nozzle to the pipeline or remove the sensor nozzle from the pipeline. The clamp can fasten the sensor nozzle more stably.

[0013] The first ring and the second ring are provided with clamp grooves, and the clamp is installed in the clamp grooves to prevent the clamp from slipping.

[0014] Advantageously, the nozzle portion is integrally formed with the body portion to reduce the number of assembly components of the sensor nozzle.

[0015] Also advantageously, the boss is integrally formed with the body portion to reduce the number of assembly parts of the sensor nozzle.

[0016] The first sealing member and the second sealing member are O-rings, and the sealing between the sensor nozzle and the pipeline can be achieved through a simple O-ring structure.

[0017] Additional features and advantages of the described sensor nozzle and tubing assembly will be set forth in the detailed description that follows, and will be apparent to those skilled in the art from the following description or will be recognized by those skilled in the art from practicing the embodiments described herein, including the following detailed description and accompanying figure illustrations.

[0043] The terms "outer surface" and "inner surface" used in this article are described when the component has a hollow cylindrical shape, wherein the "outer surface" refers to the outer surface of the cylindrical component excluding its two ends; the "inner surface" refers to the surface of the hollow opening of the cylindrical component.

[0044] For easy understanding, in the following description, the same or detailed parts or elements are denoted by the same reference numerals.

[0045] It should be understood that “first” and “second” used herein may be interchanged without affecting the description of the embodiments.

[0046] A sensor nozzle and pipeline assembly according to an embodiment of the utility model includes a pipeline 1 and a sensor nozzle 2 . Figure 1 A schematic diagram of a sensor nozzle and a pipeline 1 of a pipeline assembly according to an embodiment of the utility model is shown. Figure 2 A schematic diagram of a sensor nozzle 2 of a sensor nozzle and a pipeline assembly according to an embodiment of the present utility model is shown. Figure 3 Shows Figure 2 A cross-sectional view of the sensor nozzle taken along line AA, and Figure 4A partial cross-sectional view of a sensor nozzle and a pipeline assembly according to an embodiment of the utility model is shown.

[0047] See below Figure 1 and Figure 4 To describe the pipe 1 of the sensor nozzle and pipe assembly.

[0048] like Figure 1 and Figure 4 As shown, in this embodiment, the pipeline 1 is generally hollow cylindrical, and a pipeline opening 11 leading to the interior is opened thereon. The pipeline opening 11 is generally circular and opened at a desired detection location for at least a portion of a sensor (not shown) to enter. Since the modification to the pipeline 1 is minor (i.e., other parts of the pipeline are not modified except for opening the pipeline opening 11 on the pipeline 1), the fluid flow field in the pipeline 1 is slightly affected, thereby ensuring the detection accuracy and reducing the time and cost of modifying the pipeline 1.

[0049] It should be understood that although in the present invention, the pipeline 1 is applied to the aviation field, specifically to test flight aircraft, the application fields of the pipeline 1 may also involve fuel systems, climate systems, environmental control systems, etc. in the automotive field or the ship field.

[0050] It should also be understood that, although in this embodiment, the pipeline 1 is substantially in the shape of a hollow cylinder, and the pipeline opening 11 is substantially circular, the embodiments of the present utility model are merely exemplary and not restrictive. Moreover, in other embodiments, the pipeline 1 may also be substantially in the shape of a hollow square cylinder or other arbitrary polygonal prism, and in other embodiments, the opening 11 may also be substantially in the shape of a triangle or other arbitrary polygon as desired.

[0051] See below Figure 2-4 The sensor nozzle 2 of the sensor nozzle and pipe assembly is described below.

[0052] As shown in the figure, in this embodiment, the sensor nozzle 2 includes a nozzle portion 21 and a main body portion 22. The nozzle opening 211 of the nozzle portion 21 is aligned with the pipeline opening 11 on the pipeline 1, so as to communicate with the interior of the pipeline 1, and is used for a sensor (not shown) to be inserted into the interior of the pipeline through the nozzle opening 211 and the pipeline opening 11 to detect the fluid inside the pipeline 1.

[0053] In the embodiment of the utility model, when assembled together, the shape of the mouthpiece part 21 is designed to at least partially extend away from the main body part 22, and the mouthpiece opening 211 of the mouthpiece part 21 is shaped into a circle (i.e., having a circular cross-section) that matches the pipe opening 11 of the pipe 1, so that the sensor can be conveniently installed on the mouthpiece part 21 and pass through the mouthpiece opening 211 and the pipe opening 11. Therefore, a variety of sensors can be adapted by the shape of the mouthpiece part 21 to facilitate the installation of the sensor.

[0054] It should be understood that, although in the embodiment of the present invention, the nozzle portion 21 is formed into a substantially hollow cylindrical shape, the present invention is not limited thereto. For example, when the pipeline opening 11 of the pipeline 1 is formed into a substantially triangular or other arbitrary polygonal shape as described above, the nozzle portion 21 may also be formed into a substantially triangular or other arbitrary polygonal shape in matching with the pipeline opening 11.

[0055] Preferably, refer to Figure 2-4 The sensor nozzle 2 includes a boss 23, which extends through the pipeline opening 11 to the interior of the pipeline 1. Figure 4 Note that the nozzle opening 211 of the nozzle portion 21 extends through the boss 23 to lead to the interior of the pipeline 1. The presence of the boss 23 prevents the sensor nozzle 2 from rotating around the pipeline 1 axially or sliding on the pipeline 1.

[0056] exist Figure 3 It can be seen from the figure that the mouthpiece 21 is located above the main body 22, while the boss 23 is located below the main body 22. In other words, the mouthpiece 21 and the boss 23 are separated by the main body 22. Figure 4 It can be seen that the size (i.e., the outer diameter) of the pipeline opening 11 is larger than the size of the boss 23, so that when the sensor nozzle 2 is installed in the pipeline 1, the boss 23 can extend through the pipeline opening 11 to the inside of the pipeline 1, while the nozzle part 21 is blocked by the main body part 22 and does not enter the inside of the pipeline 1, so as to facilitate the installation of the sensor outside the pipeline 1. Therefore, the nozzle part 21 and even the entire sensor nozzle 2 are fixed at the pipeline opening 11 through the cooperation between the boss 23 and the pipeline opening 11, which helps to achieve the reliability of the installation of the sensor nozzle 2.

[0057] Continue to refer to the attached Figure 2-4 The main body 22 of the sensor nozzle 2 is used to detachably mount the sensor nozzle 2 to the pipeline 1. Thus, different types of sensor nozzles 2 can be easily replaced to meet different parameter measurement requirements.

[0058] like Figure 2 and 4As shown, in the embodiment of the present utility model, the main body 22 of the sensor nozzle 2 is also hollow cylindrical, and includes a first ring 221, a second ring 222, a pin 223 and a fastener 224 ( Figure 4 ). The first ring 221 and the second ring 222 are rotatably connected by the pin 223, and the sensor nozzle 2 is fastened to the pipeline 1 by the fastener 224. Thus, the sensor nozzle 2 can be detachably mounted relative to the pipeline 1 by the simple hinge between the first ring 221 and the second ring 222 and the fastener 224, which helps to reduce the manufacturing cost of the sensor nozzle 2 and realize the rapid assembly and disassembly of the sensor nozzle 2 relative to the pipeline 1.

[0059] Specifically, both the first ring 221 and the second ring 222 are formed into a substantially semicircular shape, although other shapes are also possible, for example, the first ring 221 can be formed into a two-thirds circle and the second ring 222 can be formed into a one-third circle. During assembly, the first ring 221 and the second ring 222 are rotatably connected to each other at one end side by the engagement of the pin 223.

[0060] In this embodiment, the nozzle portion 21 is formed integrally with the main body portion 22. Specifically, the nozzle portion 21 is formed integrally with the first ring 221 of the main body portion 22. Further, the boss 23 is formed integrally with the main body portion 22. Specifically, the boss 23 is formed integrally with the first ring 221 of the main body portion 22. Thus, the number of assembly parts of the sensor nozzle 2 can be reduced, which is conducive to further reducing the manufacturing cost of the sensor nozzle 2.

[0061] In this embodiment, the fastener 224 is a clamp that is tightened or loosened around the outer surface of the main body 22 to install the sensor nozzle 2 to the pipeline or remove the sensor nozzle from the pipeline. Figure 4 As shown, a clamp can be provided on each side of the nozzle portion 21 to balance the force, thereby making it easier to fasten the sensor nozzle 2. When disassembling, the sensor nozzle 2 can be easily removed by simply loosening the clamp. Preferably, a clamp groove (not shown, covered by the fastener 224) is provided on the first ring 221 and the second ring 222 to install the fastener 224 in the form of a clamp in the clamp groove, thereby preventing the clamp from sliding laterally.

[0062] As an addition or alternative to this embodiment, the fasteners in the main body 22 can also be in the form of threaded fasteners, etc. For example, in the case of threaded fasteners, through holes aligned with each other can be formed at the position where the first ring 221 and the second ring 222 are joined, that is, at the position opposite to the pin 223. During assembly, bolts are inserted into the two through holes, and the first ring 221 and the second ring 222 are threadedly engaged with each other through nuts.

[0063] It should be understood that, although the above description is given of the case where the main body 22 has the first ring 221 and the second ring 222, this is merely exemplary and not restrictive. In other embodiments, the main body 22 may also be formed by more than three rings according to the specific shape of the pipeline.

[0064] Reference Figure 4 In a preferred embodiment of the utility model, a first seal 3 and a second seal 4 are further included. The first seal 3 is arranged around the boss 23. More specifically, the first seal 3 is arranged between the outer surface of the pipeline 1 and the inner surface of the main body 22, which is different from the seal of the prior art that is installed between the boss 23 and the pipeline opening 11, so that once the sensor nozzle 2 is installed, the first seal 3 can be clamped between the sensor nozzle 2 and the pipeline 1 to achieve a sealing effect without requiring the size of the pipeline opening. The second seal 4 is arranged around the pipeline 1. More specifically, in this embodiment, the pipeline 1 has a sealing groove 12 formed around the outer surface of the pipeline 1, and the second seal 4 is installed in the sealing groove 12. Further preferably, the sealing groove 12 is formed around the pipeline 1 at both sides of the pipeline opening 11 to form two sealing grooves 12. Correspondingly, there are also two second seals 4 to seal at both sides of the pipeline opening 11. Of course, three or more second seals 4 and three or more sealing grooves 12 can be provided. Even the number of the second sealing members 4 may not correspond to the number of the sealing grooves 12. The above examples are all included in the scope of the present invention.

[0065] It should be understood that, although the embodiment of the present invention shows a sealing groove 12 formed around the outer surface of the pipeline 1 to facilitate fixed installation of the second sealing member 4, this is merely exemplary and not restrictive. In other embodiments, the sealing groove may be provided on the sensor nozzle 2 around the inner surface of the sensor nozzle 2.

[0066] Thus, after the sensor nozzle 2 is installed to the pipeline 1 and fastened with the fastener 224 , the first seal 3 and the second seal 4 are compressed between the sensor nozzle 2 and the pipeline 1 , thereby providing sealing between the sensor nozzle 2 and the pipeline 1 and preventing leakage of the fluid in the pipeline 1 .

[0067] Specifically, in this embodiment, the sealing member is an O-ring. Thus, the sealing between the sensor nozzle 2 and the pipeline 1 can be achieved through a simple O-ring structure, which helps to reduce the manufacturing cost of the sensor nozzle 2. Of course, other types of sealing members are optional.

[0068] In addition, refer to Figure 2 A rubber strip 225 is provided at the end side where the first ring 221 and the second ring 222 are joined to enhance the sealing performance of the main body 22 when it is installed around the pipeline 1 .

[0069] Reference Figure 5 , shows an additional embodiment of the utility model, which shows a recovery connector 5 that replaces the sensor nozzle. The recovery connector 5 is similar to the sensor nozzle described previously, and it also includes a main body portion, and the main body portion includes a first ring 221, a second ring 222, a pin 223, and a fastener (not shown), which have been previously described and will not be repeated below. The difference between the recovery connector 5 is that the recovery connector 5 does not include a nozzle portion, but only includes a boss 23, which extends into the pipeline in a manner similar to that described previously. The recovery connector 5 does not have an opening that connects the pipeline to the external environment.

[0070] The sensor nozzle and pipeline assembly of the utility model has the following technical advantages:

[0071] a) The sensor nozzle and pipeline assembly of the utility model can be widely used in the test and modification of fluid pipelines in fuel systems, inerting systems, environmental control systems, etc., and can be developed in series;

[0072] b) The sensor nozzle and pipeline assembly of the utility model can adapt to various sensor interfaces, and the modification plan is flexible;

[0073] c) Under the premise of meeting the test requirements, the sensor nozzle and pipeline assembly of the utility model can use only one opening for the pipeline, and replace different sensor nozzles to measure multiple parameters, or replace different sensor selections to facilitate troubleshooting. Therefore, the assembly can be used for multiple different test flight subjects without removing the pipeline, thereby saving the time and cost of pipeline modification;

[0074] d) Since the sensor nozzle and pipeline assembly of the utility model make little modification to the pipeline, the influence on the fluid flow field in the pipeline is small, so the test accuracy can be guaranteed;

[0075] e) After completing the test flight, the pipeline opening can be easily closed using the recovery connector and continued to be used, thereby reducing R&D costs;

[0076] f) The sensor nozzle is easy to disassemble and assemble;

[0077] g) The double seal design can more effectively prevent leakage of dangerous fluids such as fuel.

[0078] Although the structure and operation method of the utility model are described above in combination with the preferred embodiments, it should be recognized by those skilled in the art that the above examples are only for illustration and cannot be used as limitations of the utility model. Therefore, the utility model can be modified and varied, and these modifications and variations will fall within the scope defined by the claims attached to this application.
