Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of detection instruments, in particular to a temperature measuring element with a special-shaped shock-resistant structure. Background Art
[0002] When using a temperature measuring element to measure the temperature in a pipeline, generally, the temperature measuring element is directly inserted into the pipeline, and the temperature of the gas or liquid in the pipeline is detected by the temperature measuring element, and then the detected information is sent to the control system. However, since the fixing structure between the sleeve of the temperature measuring element and the pipeline is unstable, it will affect the temperature measurement accuracy. In addition, affected by the temperature measurement object, the probe will collide and rub against the inner wall of the pipeline, which is likely to cause damage to the probe, is not conducive to the long-term use of the temperature measuring element, and will affect the temperature measurement accuracy of the temperature measuring element.
[0003] Therefore, the prior art has defects and needs to be improved. Summary of the Utility Model
[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a temperature measuring element with a special-shaped shock-resistant structure.
[0005] The technical solution of the utility model is as follows: A temperature measuring element with a special-shaped shock-resistant structure is provided, including: a sleeve, and a drum spring sleeved on the sleeve, a clamping sleeve is arranged on the sleeve corresponding to the drum spring, and the clamping sleeve is connected to the front and rear ends of the drum spring.
[0006] Further, the drum spring is in a lantern shape with a larger outer diameter in the middle and smaller outer diameters at both ends.
[0007] Further, an external thread is arranged on the sleeve, an internal thread is arranged on the clamping sleeve corresponding to the external thread, and the clamping sleeve is connected and fixed to the sleeve by a threaded connection method.
[0008] Further, a wire is inserted into the sleeve, the front end of the wire is connected with a temperature measuring probe, and the temperature measuring probe passes out from the end of the sleeve.
[0009] Further, several groups of sleeves are sleeved on the wire, and several drum springs are respectively arranged on each group of sleeves.
[0010] Adopting the above scheme, the utility model arranges the drum spring on the sleeve through the clamping sleeve to fix the drum spring. When the temperature measuring element is inserted into the pipeline, the drum spring can provide a positioning function for the sleeve, so that during the flow of the temperature measurement object in the pipeline, that is, the flowing fluid such as gas or liquid, through the action of the elastic force of the drum spring itself, the sleeve is kept in a relatively stable position, and the stability of the sleeve in the pipeline is improved. Brief Description of the Drawings
[0011] Figure 1 This is a schematic structural diagram of the present utility model. Specific embodiments
[0012] The following will describe the present utility model in detail in conjunction with the accompanying drawings and specific embodiments.
[0013] Please refer to Figure 1 , the present utility model provides a temperature measuring element with a special-shaped shock-resistant structure, including: a sleeve 1 and a bellows 2 sleeved on the sleeve 1. A clamping sleeve 3 is provided on the sleeve 1 corresponding to the bellows 2, and the front and rear ends of the clamping sleeve 3 are connected to the bellows 2. The bellows 2 is arranged on the sleeve 1 through the clamping sleeve 3 to fix the bellows 2. When the temperature measuring element is inserted into the pipeline, the bellows 2 can provide a positioning function for the sleeve 1. Thus, during the flow of the fluid, i.e., the flowing gas or liquid, etc., which is the temperature measuring object in the pipeline, due to the action of the elastic force of the bellows 2 itself, the sleeve 1 is maintained in a relatively stable position, improving the stability of the sleeve 1 in the pipeline. Since pipelines are not all straight sections, a bellows 2 with a certain flexibility is sleeved outside the sleeve 1. When entering the bend of the pipeline, compared with a rigid protective structure, the flexible bellows 2 can bend and turn to a certain extent in the pipeline as the sleeve 1 advances, enabling the temperature measuring element to adapt to the condition requirements of different working places.
[0014] In some embodiments, the bellows 2 is in a lantern shape with a larger outer diameter in the middle and smaller outer diameters at both ends. When the bellows 2 is sleeved on the sleeve 1, the two ends of the bellows 2 are in contact with the sleeve 1, and the part with a larger outer diameter in the middle bulges outward. When the sleeve 1 is inserted into the pipeline, the part with a larger outer diameter in the middle of the bellows 2 is in contact with the inner wall of the pipeline, thus avoiding direct collision between the sleeve 1 and the inner wall of the pipeline, providing more buffer space for the sleeve 1 in the pipeline, and effectively reducing the contact area between the bellows 2 and the sleeve 1 and the pipeline, thereby effectively avoiding the deviation of the detection result caused by heat exchange due to contact.
[0015] In some embodiments, the sleeve 1 is provided with external threads, and the clamping sleeve 3 is provided with internal threads corresponding to the external threads. The clamping sleeve 3 is connected and fixed to the sleeve 1 by means of threaded connection. By threading the external threads on the sleeve 1 and the internal threads of the clamping sleeve 3, the bellows 2 is fixed by the two clamping sleeves 3 on both sides, avoiding the deviation of the bellows 2 and affecting the buffer and guiding effect on the sleeve 1.
[0016] In some embodiments, a wire 4 is inserted into the sleeve 1, and a temperature measuring probe 5 is connected to the front end of the wire 4, and the temperature measuring probe 5 passes out from the end of the sleeve 1. The temperature measuring probe 5 is passed out from the front end of the sleeve 1, so as to facilitate the effective detection of the fluid temperature in the pipeline, and the temperature data detected by the temperature measuring probe 5 is transmitted to the detection system through the wire 4 to realize the detection of the fluid temperature.
[0017] In some embodiments, a plurality of sets of sleeves 1 are sleeved on the wire 4, and a plurality of drum springs 2 are respectively arranged on each set of sleeves 1. When the position where temperature sampling detection is required is deep inside the pipeline, by arranging multiple sets of sleeves 1 and multiple sets of drum springs 2, it can effectively ensure that the wire 4 of the temperature measuring element can be provided with effective buffer protection everywhere by the drum springs 2. In some alternative embodiments, the drum spring 2 is arranged at one end close to the temperature measuring probe 5, so as to provide effective protection for the temperature measuring probe 5 and prevent the temperature measuring probe 5 from colliding with the inner wall of the pipeline, which may affect the temperature measurement accuracy of the temperature measurement object.
[0018] In summary, in the present utility model, the drum spring is arranged on the sleeve through a ferrule to fix the drum spring. When the temperature measuring element is inserted into the pipeline, the drum spring can provide a positioning function for the sleeve, so that during the flow of the temperature measurement object in the pipeline, that is, a fluid such as flowing gas or liquid, due to the action of the elastic force of the drum spring itself, the sleeve is kept in a relatively stable position, improving the stability of the sleeve in the pipeline.
[0019] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
