Description

Technical Field

[0001] This utility model relates to the field of thermocouple temperature measurement technology, and in particular to a thermocouple mounting structure and temperature measuring component. Background Technology

[0002] In thermal hydraulic experiments, temperature is one of the crucial parameters that needs to be measured and controlled. Thermocouples, due to their advantages such as fast response time, wide temperature range, and high measurement accuracy, have become commonly used temperature measuring elements in temperature measurement instruments and are widely applied in industrial production and scientific research experiments.

[0003] Micro-armored thermocouples refer to thermocouples with armor diameters ranging from 0.5 to 3.0 mm. They offer several significant advantages in temperature measurement. Firstly, their smaller size allows for flexible application in confined spaces or situations requiring bending. Secondly, their fast response time enables the measurement of rapidly changing temperatures. Additionally, their high-pressure resistance allows for use in high-pressure environments.

[0004] Currently, micro-armored thermocouples are installed on pipes or containers using a ferrule-type temperature sensing component structure. However, this installation method results in the exposure of part of the thermocouple mounting sleeve and armor wire. Because the armor shell of the micro-armored thermocouple is relatively thin and the mounting sleeve is thin overall, it is very easy for the thermocouple mounting sleeve to bend or the thermocouple armor wire to break when subjected to external mechanical damage.

[0030] Example 1:

[0031] See Figures 1 to 3This utility model discloses a thermocouple mounting structure for mounting and protecting a thermocouple 6. The mounting structure includes a mounting base 1, a clamping member 2, a sealing and positioning member 3, a mounting sleeve 4 for inserting the thermocouple 6, and a protective component 5 covering the outside of the thermocouple 6. The clamping member 2 is detachably connected to the mounting base 1. The sealing and positioning member 3 is located between the mounting base 1 and the clamping member 2, with its opposite ends abutting against the mounting base 1 and the clamping member 2, respectively. The mounting sleeve 4 passes sequentially through the clamping member 2, the sealing and positioning member 3, and the mounting base 1. The first end of the mounting sleeve 4 extends beyond the mounting base 1, and the second end extends beyond the clamping member 2. The outer periphery of the mounting sleeve 4 is in sealing contact with the sealing and positioning member 3. The protective component 5 is detachably connected to the clamping member 2 and has a receiving space 53 along the axial direction of the mounting sleeve 4 for accommodating the thermocouple 6. The mounting base 1 provides a mounting foundation and can be screwed or welded to external components such as fluid pipes 7 or container walls. The mounting base 1 has a clearance hole extending through its entire length for the mounting sleeve 4 to pass through. The clamping member 2 provides clamping force towards the mounting base 1 and can be used to provide a mounting foundation for the protective assembly 5. The sealing positioning member 3 is used to achieve a seal on the overall structure, particularly by blocking the clearance hole to prevent fluid leakage. The clamping member 2, in conjunction with the mounting base 1, compresses the sealing positioning member 3 to achieve a seal on the overall structure and to position the mounting sleeve 4. The mounting sleeve 4 is used to mount the thermocouple 6. The first end of the mounting sleeve 4 extending outside the mounting base 1 is a closed structure to prevent fluid from entering the interior of the mounting sleeve 4 during use.

[0032] In some embodiments, the protective component 5 includes a plurality of protective tubes 51 and a protective cover 52. One protective tube 51 is detachably connected to the clamping member 2, and the protective tube 51 furthest from the clamping member 2 is fixedly connected to the protective cover 52. Various connection configurations are possible, for example: Figure 2 As shown, in the first case, the protective component 5 includes a protective tube 51 and a protective cover 52. The two ends of the protective tube 51 are detachably connected to the clamping member 2 and fixedly connected to the protective cover 52, respectively. For example... Figure 3As shown, in the second case, the protective assembly 5 includes two protective tubes 51 and a protective cap 52. The two ends of one protective tube 51 are detachably connected to the clamping member 2 and detachably connected to the first end of the other protective tube 51, respectively. The second end of the other protective tube 51 is fixedly connected to the protective cap 52. In the third case, the protective assembly 5 includes three or more protective tubes 51 and a protective cap 52, arranged from the clamping member 2 to the protective cap 52. The two ends of the first protective tube 51 are detachably connected to the clamping member 2 and detachably connected to the first end of the second protective tube 51, the second end of the second protective tube 51 is detachably connected to the first end of the third protective tube 51, the second end of the third protective tube 51 is detachably connected to the first end of the fourth protective tube 51, and so on, with the second end of the last protective tube 51 fixedly connected to the protective cap 52. Understandably, the number of protective tubes 51 depends on the length of the thermocouple 6 and can be selected according to actual needs. The protective cap 52 and a single protective tube 51 can be an integral structure.

[0033] In some embodiments, the protective tube 51 is snap-fitted, screwed, or plugged into the clamping member 2, and / or the protective tube 51 is snap-fitted, screwed, or plugged into the protective cover 52. Various connection methods exist, such as the protective tube 51 snap-fitted into the clamping member 2 and the protective tube 51 snap-fitted into the protective cover 52; or the protective tube 51 is screwed into the clamping member 2 and the protective tube 51 is screwed into the protective cover 52; or the protective tube 51 is plugged into the clamping member 2 and snap-fitted into the protective cover 52, and so on. There are many other connection methods, which are not listed here. The specific connection method used between the protective tube 51 and the clamping member 2, and between the protective tube 51 and the protective cover 52, can be selected according to actual needs and is not limited here. It is understood that in some other embodiments, the connection between the protective tube 51 and the clamping member 2, and between the protective tube 51 and the protective cover 52, may also include a hybrid connection mode of snap-fit, screw, or plug-in to strengthen the fixation.

[0034] In some embodiments, the protective tube 51 sequentially includes a first connecting section 511, a main cylinder section 512, and a second connecting section 513. The first connecting section 511 is disposed closer to the clamping member 2 and is detachably connected to the clamping member 2. The second connecting section 513 is disposed closer to the protective cover 52 and is connected and fixed to the protective cover 52 or another protective tube 51. The first connecting section 511 is used to connect to the clamping member 2, achieving overall positioning and fixing of the protective tube 51. The second connecting section 513 is used to connect to the protective cover 52, achieving top coverage, or to connect to another protective tube 51, increasing the overall length of the protective assembly 5. The main cylinder section 512 is the main structure forming the accommodating space 53, accommodating the mounting sleeve 4 and the thermocouple 6 exposed outside the mounting sleeve 4. The specific structure to which the first connecting section 511 and the second connecting section 513 of each protective tube 51 are connected varies, for example: Figure 2 As shown, in the first case, the protective component 5 includes a protective tube 51 and a protective cover 52. The first connecting section 511 is detachably connected to the clamping member 2, and the second connecting section 513 is fixedly connected to the protective cover 52. Figure 3 As shown, in the second case, the protective assembly 5 includes two protective tubes 51 and a protective cover 52. The first connecting segment 511 of one protective tube 51 is detachably connected to the clamping member 2, and the second connecting segment 513 is detachably connected to the first connecting segment 511 of the other protective tube 51. The second connecting segment 513 of the other protective tube 51 is fixedly connected to the protective cover 52. In the third case, the protective assembly 5 includes three or more protective tubes 51 and a protective cover 52, arranged from the clamping member 2 to the protective cover 52. The first connecting segment 511 of the first protective tube 51 is detachably connected to the clamping member 2. The second connecting segment 513 is detachably connected to the first connecting segment 511 of the second protective tube 51. The second protective tube 51 of the second protective tube 51 is detachably connected to the first connecting segment 511 of the third protective tube 51. The second connecting segment 513 of the third protective tube 51 is detachably connected to the first connecting segment 511 of the fourth protective tube 51, and so on. The second connecting segment 513 of the last protective tube 51 is fixedly connected to the protective cover 52. Preferably, in this embodiment, all of the above-mentioned detachable connection methods adopt threaded connection methods.

[0035] In some embodiments, the protective cover 52 includes a top cover 521 and a side wall 522. The side wall 522 is detachably connected to the protective tube 51, and the top cover 521 covers the opening of the protective tube 51. The top cover 521 or the side wall 522 has a through hole for the wire 61 of the thermocouple 6 to pass through, facilitating the connection of the signal cable when installing the thermocouple 6. The through hole can be located on the top cover 521 or the side wall 522. When the through hole is located on the side wall 522, it must avoid overlapping the side wall 522 with the protective tube 51. The side wall 522 has internal threads for screwing and fixing to the protective tube 51. The through hole is not shown in the figure.

[0036] In some embodiments, the clamping member 2 includes a hollow third connecting section 21, a clamping section 22 with a through hole 23, and a hollow fourth connecting section 24, with the clamping section 22 located between the third connecting section 21 and the fourth connecting section 24. The third connecting section 21 is detachably connected to the mounting base 1, the clamping section 22 abuts against the sealing positioning member 3, and the fourth connecting section 24 is detachably connected to the protective tube 51. For example, the third connecting section 21 has an internal thread, the mounting base 1 has a corresponding external thread, and the third connecting section 21 is screwed to the mounting base 1. The fourth connecting section 24 has an external thread, the protective tube 51 has a corresponding internal thread, and the fourth connecting section 24 is screwed to the protective tube 51. The minimum diameter of the through hole 23 is larger than the diameter of the mounting sleeve 4 to avoid the installation of the mounting sleeve 4. The maximum diameter of the through hole 23 is smaller than the maximum diameter of the sealing positioning member 3. Generally, to provide sufficient clamping force, the contact area between the clamping section 22 and the sealing positioning member 3 should be as large as possible, and the diameter of the through hole 23 can be slightly larger than the mounting sleeve 4.

[0037] In some embodiments, the sealing positioning member 3 is a deformable extrusion member and is provided with a deformation groove 31, which is located on the outer periphery of the sealing positioning member 3. The deformation groove 31 is used to release the deformation of the sealing positioning member 3, and the deformation groove 31 can be formed around the outer periphery of the sealing positioning member 3 or in several symmetrical block grooves along the radial direction of the clamping member 2. The sealing positioning member 3 is provided with a central hole for the installation sleeve 4 to be inserted. Under the compression of the clamping member 2 and the mounting base 1, the pressure is directed towards the central hole and squeezes the sealing positioning member 3, so that the sealing positioning member 3 clamps the installation sleeve 4. The contact surface between the sealing positioning member 3 and the mounting base 1 and the clamping member 2 is an arc surface, which can realize the pressure concentration on the block. For example, the sealing positioning member 3 is a spherical sealing gasket, which enhances the clamping force of the sealing positioning member 3. The sealing positioning member 3 can be made of rubber material.

[0038] Example 2:

[0039] See Figure 4 and Figure 5Embodiment 2 of this utility model also discloses a temperature measuring component, including a thermocouple 6 connected to a signal cable and an installation structure for the thermocouple of Embodiment 1. The thermocouple 6 is inserted into the mounting sleeve 4, and part of the thermocouple 6 is exposed outside the mounting sleeve 4 and placed in the receiving space 53 of the protective component 5. Preferably, the thermocouple 6 can be a micro-armored thermocouple 6, and the following description takes a micro-armored thermocouple 6 as an example.

[0040] The thermocouple mounting structure includes a mounting base 1, a clamping member 2, a sealing and positioning member 3, a mounting sleeve 4 for inserting the thermocouple 6, and a protective assembly 5 covering the outside of the thermocouple 6. The clamping member 2 is detachably connected to the mounting base 1. The sealing and positioning member 3 is located between the mounting base 1 and the clamping member 2, with its opposite ends abutting against the mounting base 1 and the clamping member 2, respectively. The mounting sleeve 4 passes through the clamping member 2, the sealing and positioning member 3, and the mounting base 1 in sequence. The first end of the mounting sleeve 4 extends outside the mounting base 1, and the second end of the mounting sleeve 4 extends outside the clamping member 2. The outer periphery of the mounting sleeve 4 is in sealing contact with the sealing and positioning member 3. The protective assembly 5 is detachably connected to the clamping member 2 and has a receiving space 53 along the axial direction of the mounting sleeve 4 for accommodating the thermocouple 6.

[0041] In some embodiments, the thermocouple 6 outputs a signal via a signal cable. The protection assembly 5 has a through hole on its top or side wall, through which the signal cable extends outside the mounting structure. Specifically, the protection assembly 5 includes several protective tubes 51 and a protective cover 52. One protective tube 51 is detachably connected to the clamping member 2, and the protective tube 51 furthest from the clamping member 2 is fixedly connected to the protective cover 52. The protective cover 52 includes a top cover 521 and a side wall 522. The side wall 522 is detachably connected to the protective tube 51, and the top cover 521 covers the opening of the protective tube 51. The top cover 521 or the side wall 522 has a through hole for the wire 61 of the thermocouple 6 to pass through, facilitating the lead-out of the signal cable when installing the thermocouple 6. For example, the side wall 522 has an internal thread for screwing and fixing to the protective tube 51.

[0042] Understandably, the other structures of the thermocouple mounting structure are exactly the same as in Embodiment 1, and will not be described in detail here.

[0043] The implementation process of the temperature measuring component of this utility model is as follows:

[0044] 1) Open a temperature measuring hole 71 on the pipe 7 to ensure that the installation sleeve 4 can be inserted into the pipe 7 through the temperature measuring hole 71 for temperature measurement, and then weld the installation base 1 to the position where the temperature measuring hole 71 is opened.

[0045] 2) Install the mounting sleeve 4 on the mounting base 1 using the sealing positioning component 3 and the clamping component 2, and confirm that the insertion depth of the mounting sleeve 4 is reasonable.

[0046] 3) Insert the armored temperature measuring section of the micro-armored thermocouple 6 into the mounting sleeve 4 of the thermocouple 6, ensuring that the temperature measuring point at the end of the armor of the thermocouple 6 is inserted to the bottom of the mounting sleeve 4.

[0047] 4) Select an appropriate number of protective tubes 51 according to the length of the mounting sleeve 4 of the protruding clamping member 2 and the length of the micro armored thermocouple 6, and assemble them. The last section of protective tube 51 is screwed to the protective cover 52.

[0048] 5) Pass the wire 61 with the thermocouple 6 connector through the through hole of the protective cover 52 and connect it to the quick connector at the end of the micro-armored thermocouple 6. Then screw the protective tube 51 to the clamping part 2 to fix it.

[0049] When installing the protective tube 51 structure of the micro-armored thermocouple 6 for the first time, the medium in the fluid pipeline 7 or container needs to be emptied. After the mounting base 1 is welded, first insert the blind end of the mounting sleeve 4 (the first end of the mounting sleeve 4 extending outside the mounting base 1) into the appropriate temperature measuring position in the pipeline 7 or container. Seal and fix the mounting sleeve 4 to the mounting base 1 by the sealing positioning element 3 and the clamping element 2. Then insert the micro-armored thermocouple 6 into the mounting sleeve 4 (the mounting sleeve 4 is made of stainless steel), ensuring that the temperature measuring point of the micro-armored thermocouple 6 is inserted to the bottom of the mounting sleeve 4. Finally, install the protective tube 51 on the upper part of the exposed micro-armored thermocouple 6 and the mounting sleeve 4. If the exposed armor of the micro-armored thermocouple 6 is long, multiple sections of protective tube 51 can be installed as needed. The micro-armored thermocouple 6 and the protective tube 51 can be replaced online during subsequent operations. The protective tube 51 is screwed to the protective cover 52.

[0050] By implementing this utility model, the following beneficial effects can be achieved:

[0051] The thermocouple mounting structure of this invention features a protective component 5 that completely covers the exposed armor wires of the thermocouple 6 outside the mounting sleeve 4 and part of the mounting sleeve 4 exposed outside the clamping member 2. This prevents the thermocouple 6 and part of the mounting sleeve 4 from being exposed, thus preventing damage to the mounting sleeve 4 and the thermocouple 6, and eliminating the possibility of bending of the mounting sleeve 4 and breakage of the armor wires of the thermocouple 6. The protective component 5 is detachably connected to the clamping member 2 for easy replacement of the thermocouple 6.

[0052] The temperature measuring assembly of this invention uses a thermocouple mounting structure to fix the thermocouple 6, providing a base for temperature measurement. The protective component 5 completely covers the exposed armor threads of the thermocouple 6 outside the mounting sleeve 4 and part of the mounting sleeve 4 exposed outside the clamping member 2, preventing the thermocouple 6 and part of the mounting sleeve 4 from being exposed and thus preventing damage to the mounting sleeve 4 and the thermocouple 6. This eliminates the possibility of bending of the mounting sleeve 4 and breakage of the thermocouple 6 armor threads, maintaining the normal operation of the temperature measuring assembly and extending the service life of the thermocouple 6. When necessary, the protective component 5 and the clamping member 2 can be detachably connected for easy replacement of the thermocouple 6, reducing overall material waste.
