DETAILED DESCRIPTION

[0028] The above and other technical features and advantages of the present invention are described in more detail below with reference to the accompanying drawings.

[0029] Example 1

[0030] This embodiment provides a technical solution: a sealing ring mechanism with an air guide structure, such as Figure 1 and Figure 2 As shown, it includes a mounting ring 2, a sealing ring 1 and a guide 3.

[0031] The sealing ring 1 is sleeved on the outside of the mounting ring 2. Specifically, the mounting ring 2 includes an annular ring, and the outer surface of the annular ring is provided with an annular groove adapted to the sealing ring 1. The sealing ring 1 is installed in the annular groove to stably connect the sealing ring 1 and the mounting ring 2. The inner walls on both sides of the annular ring have extensions, which extend along the axial direction of the annular ring and are annular structures.

[0032] One end of the guide member 3 is fixed to the inner wall of the mounting ring 2, and the connection between the two can be by welding, welding or threaded connection. The specific connection method is set according to actual needs. The other end of the guide member 3 extends into the pipe 200 and has a guide portion, which faces the upstream direction of the airflow, that is, referring to Figure 1 When the upstream airflow in the pipeline 200 flows down, due to the setting of the guide part, the airflow in the pipeline 200 can be guided to one side of the mounting ring 2, that is, the sensor 100 can fully receive the airflow in the pipeline 200 to improve the monitoring accuracy.

[0033] It should be noted that the overall width of the guide member 3 can be set as needed. For example, when the width of the guide member 3 is smaller than the width of the mounting ring 2, a connecting block needs to be set between the guide member 3 and the inner wall of the mounting ring 2 to ensure that the mounting ring 2 and the guide member 3 can be smoothly connected.

[0034] Example 2

[0035] This embodiment is further optimized based on the first embodiment, and the parts that are the same as the above technical solutions will not be repeated here. Figure 2 As shown, in order to better implement the present invention, the following configuration is particularly adopted:

[0036] The guide member 3 includes a first transverse plate 311 fixed to the inner wall of the mounting ring 2. The end of the first transverse plate 311 away from the mounting ring 2 is connected to an inclined plate 312, and the inclined plate 312 is located in the pipe 200. The inclined direction of the inclined plate 312 is toward the upstream direction of the airflow. The angle between the first transverse plate 311 and the inclined plate 312 is 15°-60°. In the actual production process, the specific angle is produced according to needs.

[0037] When the airflow in the pipe 200 flows to the inclined plate 312, the inclined plate 312 will guide the airflow to one side, changing the direction of the airflow, and then flow to one side of the mounting ring 2 under the obstruction of the first transverse plate 311 to enter the sensor 100.

[0038] It should be noted that the inclined plate 312 can be configured as a semicircular structure, which not only improves the appearance but also rounds the sharp corners of the inclined plate 312 to improve safety. In addition, the first horizontal plate 311 and the inclined plate 312 can be integrally formed, for example, by plastic casting or metal bending, or by welding.

[0039] Example 3

[0040] This embodiment is further optimized based on the second embodiment, and the parts that are the same as the above technical solutions will not be repeated here. Figure 3 As shown, in order to better implement the present invention, the following configuration is particularly adopted:

[0041] Both sides of the first transverse plate 311 and the inclined plate 312 are provided with first protective side plates 313. The setting of the first protective side plates 313 serves to isolate other external airflows and prevent the guided airflow from being dispersed when the airflow is guided along the first transverse plate 311 and the inclined plate 312, so as to ensure smooth and stable flow.

[0042] Example 4

[0043] This embodiment is further optimized based on the second embodiment, and the parts that are the same as the above technical solutions will not be repeated here. Figure 4 As shown, in order to better implement the present invention, the following configuration is particularly adopted:

[0044] The first transverse plate 311 is a telescopic plate that can be retracted to adjust the length of the first transverse plate 311 to adapt to different usage requirements, such as adjusting the flow rate of the guided airflow, or adapting to mounting bases of different lengths to ensure that the inclined plate 312 can smoothly extend into the pipe 200.

[0045] The first horizontal plate 311 includes a flat storage shell 3111 fixed to the inner wall of the mounting ring 2. A telescopic plate portion 3112 is slidably inserted into the inner cavity of one end of the flat storage shell 3111 away from the mounting ring 2. The length of the entire first horizontal plate 311 can be adjusted by adjusting the telescopic plate portion 3112 to extend the length of the inner cavity of the flat storage shell 3111.

[0046] Furthermore, a long waist hole 3113 is provided on at least one side wall of the flat storage shell 3111, and the telescopic plate portion 3112 is threadedly connected with a bolt 3114 that passes through the long waist hole 3113. By tightening the bolt 3114, it is pressed against the flat storage shell 3111, thereby fixing the flat storage shell 3111 and the telescopic plate portion 3112.

[0047] Furthermore, an inclined surface is processed on the upper surface of the end of the flat storage shell 3111 to ensure the smooth connection between the flat storage shell 3111 and the telescopic plate portion 3112 and avoid protrusions that block air flow.

[0048] Example 5

[0049] This embodiment is further optimized based on the first embodiment, and the parts that are the same as the above technical solutions will not be repeated here. Figure 5 As shown, in order to better implement the present invention, the following configuration is particularly adopted:

[0050] The guide member 3 includes a second horizontal plate 331 fixed to the inner wall of the mounting ring 2. The end of the second horizontal plate 331 away from the mounting ring 2 is connected to an arc-shaped plate 332, and the arc-shaped plate 332 faces the upstream direction of the airflow. Compared with the above embodiments, this embodiment has an arc-shaped structure, so that the airflow guiding path is smoother and the airflow turns more smoothly.

[0051] Example 6

[0052] This embodiment is further optimized based on the fifth embodiment, and the same parts as the above technical solutions will not be repeated here. Figure 6 As shown, in order to better implement the present invention, the following configuration is particularly adopted:

[0053] Both sides of the second horizontal plate 331 and the curved plate 332 are provided with second protective side plates 333. The second protective side plates 333 are provided to block other external airflows and prevent the guided airflow from being dispersed when the airflow is guided along the second horizontal plate 331 and the curved plate 332, thereby ensuring smooth and stable flow.

[0054] Example 7

[0055] This embodiment is further optimized based on the first embodiment, and the parts that are the same as the above technical solutions will not be repeated here. Figure 7 As shown, in order to better implement the present invention, the following configuration is particularly adopted:

[0056] The guide member 3 includes a straight arc plate 321 fixed to the inner wall of the mounting ring 2. The end of the straight arc plate 321 away from the mounting ring 2 is connected to a curved arc plate 322, and the curved arc plate 322 faces the upstream direction of the airflow. The cross-sections of the straight arc plate 321 and the curved arc plate 322 are both arc structures.

[0057] Compared with the above embodiments, this embodiment has a simpler structure and avoids dispersion of the guided airflow to ensure smooth and stable flow. It also makes the airflow guiding path smoother and the airflow turning smoother.

[0058] The above description is merely a preferred embodiment of the present invention and is intended to be illustrative rather than restrictive of the present invention. Those skilled in the art will appreciate that many changes, modifications, and even equivalents may be made to the present invention within the spirit and scope of the claims, and all of these changes will fall within the scope of protection of the present invention.
