Description

Sensor connects mouth and pipeline subassembly

Technical Field

The utility model belongs to the field of civil aircraft test flight, and particularly relates to a sensor nozzle and a pipeline assembly.

Background

During the development of civil aircraft, a great deal of tests are often required to verify the functions and performances of various systems of the aircraft. When carrying out flight tests such as fuel oil, inerting, environmental control systems and the like, a sensor is often required to be additionally arranged on an oil supply or air supply pipeline to measure parameters such as the temperature, the pressure, the flow and the like of fluid in the pipeline. In order to attach the sensor to the pipeline, a nipple is required on the pipeline that mates with the sensor mounting interface so that the sensor can sense a fluid parameter inside the pipeline through the nipple.

At present, it is common practice to modify the pipeline and weld the sensor nipple on the pipeline. The pipeline welded with the sensor connector needs to be disassembled after the aircraft completes the flight test, and the original aircraft pipeline installation machine is restored. However, different flight test subjects have different requirements on test parameters, the types, the models and the like of the sensors may need to be replaced in the test flight process of the same flight test subject, and the requirements on the measured parameters may be more due to limited refittable space for a pipeline with an elbow. In these scenarios, only piping is often made new to meet different test requirements. The refitted pipeline of the welding sensor connector is low in repeated use rate, high in refitting cost for many times, long in implementation period and sometimes seriously affects project progress.

In order to solve the problem of low reuse of the pipe welded with the sensor nipple, a sensor base has been proposed which can be detachably engaged with an increased opening in the pipe without being welded thereto, and sealed with a sealing ring. However, in this design, the sealing form of the sealing ring and the pipeline is a single sealing form of the sealing ring and the cylindrical surface of the opening of the pipeline, and the requirement on the size of the opening of the pipeline is high. If the size of the pipeline opening is bigger, the sealing effect is not good, and if the size of the pipeline opening is smaller, the problem that the sealing ring is cut by the pipe wall easily occurs. Furthermore, the reliability of the form of a single seal is inadequate for pipelines in which the internal fluid is a flammable liquid or a hazardous gas.

Therefore, how to design a detachable pipeline modification form which is reliable in sealing and can adapt to various interfaces and fast switching is a technical problem to be solved.

Disclosure of utility model

In order to solve the problem of insufficient tightness of the conventional detachable sensor interface, the utility model designs a sensor connector and a pipeline assembly, which realize reliable tightness by utilizing a detachable double-sealed pipeline sensor connector and a pipeline. In addition, the sensor connector and the pipeline assembly can be replaced under the condition that the modified pipeline is not replaced, so that the sensor connector is suitable for the sensor mounting requirements of different interfaces, the modified pipeline can be reused, the cost is reduced, and the efficiency is improved.

The sensor tap and the pipeline assembly comprise a pipeline and a sensor tap, wherein the pipeline is provided with a pipeline opening which is communicated to the inside, the sensor tap comprises a tap part, the tap opening of the tap part is aligned with the pipeline opening of the pipeline so as to be communicated with the inside of the pipeline, the sensor tap is used for being inserted into the inside of the pipeline through the tap opening and the pipeline opening, a main body part is used for detachably mounting the sensor tap to the pipeline, and a boss extends into the inside of the pipeline through the pipeline opening, wherein the sensor tap and the pipeline assembly further comprise a first sealing piece and a second sealing piece, the first sealing piece is arranged around the boss, and the second sealing piece is arranged around the pipeline.

In a preferred embodiment of the utility model, the first seal is disposed between an outer surface of the conduit and an inner surface of the body portion. This allows the first seal to be clamped directly between the sensor hub and the tubing to achieve a sealing effect without requiring the size of the tubing opening.

In a preferred embodiment of the utility model, the conduit has a sealing groove formed around an outer surface of the conduit, and the second seal is mounted in the sealing groove. The second seal provides a second reseal to more effectively prevent leakage of dangerous fluids such as fuel.

In one embodiment, seal grooves are formed around the pipe on both sides of the pipe opening.

The body portion 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 nipple is removably mounted to the pipeline by the fastener. Thus, the sensor nipple can be conveniently mounted or dismounted by only engaging or rotating the first ring and the second ring through the pin shaft.

In an embodiment of the utility model, the fastener is a clip that tightens or loosens around the outer surface of the body portion to mount or remove the sensor hub to or from the pipeline. The clip can more stably fasten the sensor tap.

The first ring and the second ring are provided with clamping grooves, and the clamp is installed in the clamping grooves to prevent the clamp from sliding.

Advantageously, the mouthpiece portion is integrally formed with the body portion to reduce the number of assembly components of the sensor mouthpiece.

It is also advantageous that the boss is integrally formed with the body portion to reduce the number of assembly parts of the sensor nozzle.

The first sealing element and the second sealing element are O-shaped sealing rings, and the tightness between the sensor connector and the pipeline can be realized through a simple O-shaped sealing ring structure.

A sensor hub and tubing assembly according to one embodiment of the present utility model includes tubing 1 and sensor hub 2. Fig. 1 shows a schematic view of a pipe 1 of a sensor tap and pipe assembly according to an embodiment of the utility model, fig. 2 shows a schematic view of a sensor tap 2 of a sensor tap and pipe assembly according to an embodiment of the utility model, fig. 3 shows a cross-sectional view of the sensor tap of fig. 2 taken along line A-A, and fig. 4 shows a partial cross-sectional view of the sensor tap and pipe assembly according to an embodiment of the utility model.

The sensor mouthpiece and the tubing 1 of the tubing assembly are described below with reference to fig. 1 and 4.

As shown in fig. 1 and 4, in this embodiment, the pipe 1 is generally hollow cylindrical and has a pipe opening 11 opened therein to the inside, the pipe opening 11 being generally circular and opened at a desired detection site for at least a part of a sensor (not shown) to enter. Since the modification to the pipeline 1 is small (i.e., the other part of the pipeline is not modified except for the pipeline opening 11 formed in the pipeline 1), the influence of the fluid flow field in the pipeline 1 is small, so that the detection accuracy can be ensured, and the modification man-hour and cost of the pipeline 1 can be reduced.

It should be understood that although in the present utility model the pipeline 1 is applied in the field of aviation, in particular in pilot planes, the field of application of the pipeline 1 may also relate to fuel systems, to an estrus system, to a climate control system, etc. in the automotive field or in the marine field.

It should also be understood that while in this embodiment the conduit 1 is generally hollow cylindrical and the conduit opening 11 is generally circular, embodiments of the present utility model are merely exemplary and not limiting. In other embodiments, the pipe 1 may have a substantially hollow square tubular shape or any other polygonal prismatic shape, and in other embodiments, the opening 11 may have a substantially triangular shape or any other polygonal shape, for example, as desired.

The sensor nipple 2 of the sensor nipple and the line assembly is described below with reference to fig. 2-4.

As shown, in this embodiment, the sensor tap 2 includes a tap portion 21 and a main body portion 22. The nipple opening 211 of the nipple portion 21 is aligned with the tube opening 11 on the tube 1 so as to communicate with the interior of the tube 1 for insertion of a sensor (not shown) into the interior of the tube through the nipple opening 211 and the tube opening 11 to detect fluid inside the tube 1.

In an embodiment of the utility model, the shape of the nipple portion 21 is designed to extend at least partially away from the body portion 22 when assembled together, and the nipple opening 211 of the nipple portion 21 is shaped to match the circular shape of the tube opening 11 of the tube 1 (i.e. to have a circular cross section), so that the sensor can be conveniently mounted on the nipple portion 21 and through the nipple opening 211 and the tube opening 11. Thereby, various sensors can be adapted by the shape of the nozzle portion 21 to facilitate the mounting of the sensors.

It should be understood that although in the embodiment of the present utility model, the nozzle portion 21 is formed in a substantially hollow cylindrical shape, the present utility model is not limited thereto. For example, in the case where the pipe opening 11 of the pipe 1 is formed in a substantially triangular shape or any other polygonal shape as described above, the nipple portion 21 may be formed in a substantially triangular shape or any other polygonal shape in cooperation with the pipe opening 11.

Preferably, referring to fig. 2-4, the sensor hub 2 includes a boss 23, which boss 23 extends through the conduit opening 11 to the interior of the conduit 1, as shown in fig. 4. Note that the nipple opening 211 of the nipple portion 21 extends through the boss 23 to open into the interior of the tube 1. The presence of the boss 23 is such that the sensor hub 2 does not rotate axially around the pipeline 1 or slip on the pipeline 1.

In fig. 3 it can be seen that the mouthpiece portion 21 is located above the body portion 22 and the boss 23 is located below the body portion 22, in other words the mouthpiece portion 21 and the boss 23 are separated by the body portion 22. It can be seen in fig. 4 that the size (i.e. the outer diameter) of the pipe opening 11 is larger than the size of the boss 23, so that when the sensor tap 2 is mounted to the pipe 1, the boss 23 can extend through the pipe opening 11 into the inside of the pipe 1, while the tap portion 21 is blocked by the body portion 22 from entering the inside of the pipe 1, so that the sensor is mounted outside the pipe 1. Thereby, the fitting of the boss 23 with the pipe opening 11 fixes the nipple portion 21 and thus the entire sensor nipple 2 at the pipe opening 11, contributing to achieving reliability of the installation of the sensor nipple 2.

With continued reference to fig. 2-4, the body portion 22 of the sensor hub 2 is used to removably mount the sensor hub 2 to the pipeline 1. Thereby, different types of sensor taps 2 can be easily replaced to accommodate different parameter measurement requirements.

As shown in fig. 2 and 4, in an embodiment of the present utility model, the body portion 22 of the sensor nipple 2 is also hollow and cylindrical, including a first ring 221, a second ring 222, a pin 223, and a fastener 224 (fig. 4). The first ring 221 and the second ring 222 are rotatably connected by a pin 223, and the sensor nipple 2 is fastened to the pipe 1 by a fastener 224. The removability of the sensor hub 2 with respect to the line 1 can thereby be achieved by a simple articulation between the first ring 221 and the second ring 222 and the fastening 224, which contributes to a reduction in the manufacturing costs of the sensor hub 2 and a rapid removal of the sensor hub 2 with respect to the line 1.

Specifically, both the first ring 221 and the second ring 222 are formed in a substantially semicircular shape, although other shapes are possible, for example, the first ring 221 may be formed in a two-thirds circular shape and the second ring 222 may be formed in a one-third circular shape. In assembly, the first ring 221 and the second ring 222 are rotatably connected to each other at one end side by the hinge action of the pin 223.

In this embodiment, the nozzle portion 21 is integrally formed with the main body portion 22. Specifically, the nozzle portion 21 is integrally formed with the first ring 221 of the main body portion 22. Further, the boss 23 is integrally formed with the main body portion 22. Specifically, the boss 23 is integrally formed with the first ring 221 of the body portion 22. Thereby, the number of assembly parts of the sensor tap 2 can be reduced, thereby contributing to further reduction in manufacturing cost of the sensor tap 2.

In this embodiment, the fastener 224 is a clip that tightens or loosens around the outer surface of the body portion 22 to mount or remove the sensor hub 2 to or from the pipeline. Preferably, as shown in fig. 4, clips may be provided one on each side of the nozzle portion 21 to facilitate force balancing, and thus the sensor nozzle 2 may be more easily fastened. When the sensor connector 2 is detached, the sensor connector 2 can be detached easily only by loosening the clamp. Preferably, clip grooves (not shown, covered by the fastener 224) are provided on the first ring 221 and the second ring 222 to mount the fastener 224 in the form of a clip in the clip grooves, thereby preventing the clip from sliding laterally.

Additionally or alternatively to this embodiment, the fasteners in the body portion 22 may likewise be in the form of threaded fasteners or the like. For example, in the case of a threaded fastener, through holes respectively formed to be aligned with each other may be formed at positions where the first ring 221 and the second ring 222 are engaged, i.e., positions opposite to the pin 223, and at the time of 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 by nuts.

It should be appreciated that while the case where the body portion 22 has the first ring 221 and the second ring 222 has been described above, this is merely exemplary and not limiting. In other embodiments, the body portion 22 may be formed from more than three rings depending on the particular shape of the conduit.

Referring to fig. 4, in a preferred embodiment of the present utility model, a first seal 3 and a second seal 4 are further included. The first seal 3 is disposed around the boss 23. More specifically, the first seal 3 is provided between the outer surface of the pipe 1 and the inner surface of the main body portion 22, unlike the prior art seal which is mounted between the boss 23 and the pipe opening 11, so that the first seal 3 can be sandwiched between the sensor hub 2 and the pipe 1 to achieve a sealing effect once the sensor hub 2 is mounted, without requiring the size of the pipe opening. A second seal 4 is provided around the pipeline 1. More specifically, in the present embodiment, the pipe 1 has a seal groove 12 formed around the outer surface of the pipe 1, and the second seal 4 is installed in the seal groove 12. Further preferably, seal grooves 12 are formed around the piping 1 at both sides of the piping opening 11 to form two seal grooves 12. Correspondingly there are two second seals 4 to seal at both sides of the pipe opening 11. Of course, three or more second seals 4 and three or more seal grooves 12 may be provided. Even the number of second seals 4 may not correspond to the number of seal grooves 12. The above examples are included within the scope of the present utility model.

It should be understood that while the embodiment of the present utility model is shown with the seal groove 12 formed around the outer surface of the pipe 1 to facilitate fixedly mounting the second seal 4, this is merely exemplary and not limiting. In other embodiments, a seal groove may be provided on the sensor nozzle 2 around the inner surface of the sensor nozzle 2.

Thus, after the sensor hub 2 is mounted to the pipeline 1 and fastened with the fastener 224, the first seal 3 and the second seal 4 are compressed between the sensor hub 2 and the pipeline 1, thereby providing a seal between the sensor hub 2 and the pipeline 1 against leakage of fluid within the pipeline 1.

Specifically, in the present embodiment, the seal is an O-ring seal. Therefore, the tightness between the sensor connector 2 and the pipeline 1 can be realized through a simple O-shaped sealing ring structure, and the manufacturing cost of the sensor connector 2 can be reduced. Of course other types of seals are optional.

Further, referring to fig. 2, a rubber strip 225 is provided at the end side position where the first ring 221 and the second ring 222 are joined to strengthen the sealing of the main body portion 22 when installed around the piping 1.

Referring to fig. 5, an additional embodiment of the present utility model is shown showing a restoring connector 5 in place of a sensor nozzle, the restoring connector 5 being similar to the previously described sensor nozzle, and likewise comprising a body portion including 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 described in detail. The restoring connection 5 differs in that the restoring connection 5 does not comprise a nipple portion, but only a boss 23, which boss 23 extends into the pipeline in a similar manner to that described previously. The restoring connection 5 has no opening for connecting the pipeline to the external environment.

The sensor connector and the pipeline assembly have the following technical advantages:

a) The sensor connector and the pipeline assembly can be widely used for testing and refitting the fluid pipelines of a fuel system, an inerting system, a ring control system and the like, and can be developed in series;

b) The sensor connector and the pipeline of the pipeline assembly can adapt to various different sensor interfaces, and the modification scheme is flexible;

c) On the premise of adapting to test requirements, the sensor connector and the pipeline of the pipeline assembly can only use one opening, and different sensor connectors can be replaced to measure various parameters, or different sensor types can be replaced to remove faults, so that the assembly can be used for a plurality of different test flight subjects without dismantling the pipeline, and the time cost of pipeline modification is saved;

d) The sensor connector and the pipeline assembly have small modification to the pipeline, so that the influence on the fluid flow field in the pipeline is small, and the testing precision can be ensured;

e) After the test flight is finished, the recovery connecting piece can be conveniently used for closing the pipeline opening, and the pipeline opening can be continuously used, so that the research and development cost is reduced;

f) The sensor connector is convenient to assemble and disassemble;

g) The design of the double sealing elements can effectively prevent dangerous fluids such as fuel oil and the like from leaking.

While the structure and method of operation of the present utility model have been described in connection with preferred embodiments, those of ordinary skill in the art will recognize that the above examples are for illustrative purposes only and are not intended to be limiting. Accordingly, the present utility model is susceptible to modification and variation, which are all intended to fall within the scope of the present utility model as defined in the appended claims.
