Description

Technical Field

[0001] This utility model relates to the technical field of temperature measurement in chemical pipelines, and in particular to a pipeline temperature measurement device. Background Technology

[0002] Currently, temperature measurement technology for chemical pipelines involves inserting a temperature sensing element into the pipeline. However, there are certain requirements for the insertion depth of the sensing element. Therefore, it is necessary to enlarge the diameter of a section of the pipeline and then measure the temperature using the sensing element in the enlarged section to meet the insertion depth requirements. This measurement method requires connecting the separate main pipeline body and the enlarged section. The current connection method is welding, which is cumbersome, inefficient, requires specialized welding workers, and is difficult to perform in confined spaces. Utility Model Content

While meeting the technical requirements for temperature measurement insertion depth, it is easy to assemble and disassemble, highly efficient, and does not limit the size of the operating area.

[0004] The specific technical solution is as follows:

[0007] In the aforementioned pipe temperature measuring device, the measuring portion of the temperature measuring element extends into the central axis of the expanded diameter pipe.

[0038] Furthermore, as a preferred embodiment, the side wall of the expanded diameter pipe 92 is provided with a mounting hole, the temperature sensing element 93 extends into the expanded diameter pipe 92 through the mounting hole, and a sealing ring is provided between the temperature sensing element 93 and the mounting hole of the expanded diameter pipe 92.

[0041] Based on the above, this utility model also has the following embodiments:

[0042] For further embodiments of this utility model, please refer to... Figures 1 to 5As shown, each clamping structure 94 includes: an inner support 1, a locking head 2, and a locking mechanism 3. The inner support 1 is installed on the inner side of the end of the pipe body 91 or the inner side of the end of the expanded diameter pipe 92, and supports the inner wall of the pipe body 91 or the inner wall of the expanded diameter pipe 92. The locking head 2 is sleeved on the outer side of the pipe body 91 or the outer side of the expanded diameter pipe 92. The locking head 2 is a hollow structure with one end open. One end of the locking mechanism 3 extends between the locking head 2 and the pipe body 91 or the expanded diameter pipe 92. When the locking mechanism 3 is fixedly connected to the locking head 2, it presses the pipe body 91 or the expanded diameter pipe 92 to make the locking mechanism 3 and the pipe body 91 or the expanded diameter pipe 92 seal together. The other end of the locking mechanism 3 is threadedly connected to the connecting sleeve 95.

[0043] In a further embodiment of this utility model, the portion of the locking mechanism 3 extending into the locking head 2 corresponds to the inner support 1.

[0044] In a further embodiment of this utility model, the length of the portion of the locking mechanism 3 extending into the locking head 2 is not greater than the length of the inner support 1.

[0045] In a further embodiment of the present invention, the end of the inner support 1 extends outward to the periphery with a protruding ring 11, which is matched with the end of the pipe body 91 or the expanded diameter pipe 92.

[0046] This utility model uses the locking head 2 and the locking mechanism 3 to clamp the pipe body 91 or the expanded diameter pipe 92 while ensuring sealing. The inner support 1 can prevent the pipe body 91 or the expanded diameter pipe 92 from deforming when clamped, and facilitates disassembly and assembly.

[0047] In a further embodiment of the present invention, the locking mechanism 3 includes: a clamping head 31, which extends between the locking head 2 and the pipe body 91 or the expanded diameter pipe 92. The clamping head 31 is fixedly connected to the locking head 2 and presses the pipe body 91 or the expanded diameter pipe 92 to achieve a sealed fit between the clamping head 31 and the pipe body 91 or the expanded diameter pipe 92.

[0048] In a further embodiment of the present invention, the locking mechanism 3 further includes a wedge assembly 32, which is disposed between the locking head 2 and the pipe body 91 or the expanded diameter pipe 92.

[0049] In a further embodiment of the present invention, the clamping head 31 and the inner wall of the locking head 2 are fixedly connected to each other, so that the wedge clamping assembly 32 is clamped between the pipe body 91 or the expanded diameter pipe 92, and the clamping head 31 is sealed to the pipe body 91 or the expanded diameter pipe 92.

[0050] In a further embodiment of the present invention, the wedge clamping component 32 is operably abutted against the outer wall of the pipe body 91 or the expanded diameter pipe 92, so that the wedge clamping component 32 deforms or displaces, reducing the inner diameter of the wedge clamping component 32, thereby clamping the pipe body 91 or the expanded diameter pipe 92.

[0051] In a further embodiment of the present invention, the wedge clamping component 32 abuts against the other end of the locking head 2 and the clamping head 31.

[0052] In a further embodiment of the present invention, the wedge clamping assembly 32 has a pressing inclined surface 34, and the end of the clamping head 31 has a pressing inclined surface 33. The pressing inclined surface 33 presses against the pressing inclined surface 34 to cause the wedge clamping assembly 32 to deform or displace, thereby reducing the inner diameter of the wedge clamping assembly 32 and clamping the pipe body 91 or the expanded diameter pipe 92.

[0053] In a further embodiment of the present invention, the wedge clamping assembly 32 includes at least two wedge clamping blocks 35, which are disposed between the locking head 3 and the pipe body 91 or the expanded diameter pipe 92 and are distributed circumferentially along the pipe body 91 or the expanded diameter pipe 92. Each wedge clamping block 35 has an inclined surface, and the multiple inclined surfaces form a pressing inclined surface 34.

[0054] In a further embodiment of the present invention, when the clamping head 31 is fixedly connected to the inner wall of the locking head 2, the clamping head 31 presses against multiple wedge blocks 35, and the pressing inclined surface 33 presses against multiple inclined surfaces, so that the two wedge blocks 35 clamp the pipe body 91 or the expanded diameter pipe 92.

[0055] By setting multiple inclined surfaces, the clamping head 31 and the locking head 2 are connected to squeeze the wedge clamping component 32, thereby reducing its inner diameter and improving the connection strength between the wedge clamping component 32 and the pipe body 91 or the expanded diameter pipe 92.

[0056] In a further embodiment of the present invention, the inner wall of the wedge clamping assembly 32 is provided with at least one annular groove 36 along its axial direction.

[0057] In a further embodiment of the present invention, the inner wall of each wedge block 35 is provided with at least one clamping groove along the circumference of the pipe body 91 or the expanded diameter pipe 92, and the clamping grooves of the multiple wedge blocks form an annular groove 36.

[0058] In a further embodiment of this utility model, at least one sealing ring is provided between the clamping head 31 and the pipe body 91 or the expanded diameter pipe 92.

[0059] In a further embodiment of the present invention, the locking head 2 has a relief groove 22, which corresponds to the wedge clamping component 32. The relief groove 22 is designed to prevent the clamping head 31 from interfering with the locking head 2 along the axial direction.

[0060] This utility model connects the pipe body 91 and the expanded diameter pipe 92 through a quick-installation structure. While meeting the technical requirements for temperature measurement insertion depth, it is easy to assemble and disassemble, highly efficient, and does not limit the size of the working area.

[0061] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
