Detailed Description of the Embodiment

[0030] The following will further describe the present application in detail Figure 1 with reference to the accompanying drawings.

[0031] The embodiment of the present application discloses a device for manually adjusting the magnitude of wind pressure in a pipeline. Refer to Figure 1 , a device for manually adjusting the magnitude of wind pressure in a pipeline includes a first sleeve 1, a second sleeve 2, a third sleeve 3, a first fixing component 4, and a second fixing component 5. The first sleeve 1 and the third sleeve 3 are respectively sleeved on both ends of the second sleeve 2. The first fixing component 4 is used to fix the first sleeve 1 and the second sleeve 2. The second fixing component 5 is used to fix the second sleeve 2 and the third sleeve 3.

[0032] Refer to Figure 1, the inner wall of the second sleeve 2 near one end of the third sleeve 3 is fixed with multiple first blades at equal intervals along the circumferential direction. The first blade is connected to the other first blades at one end away from the inner wall of the second sleeve 2. The cavity between adjacent first blades has the same shape as the first blade. The inner wall of the third sleeve 3 near one end of the second sleeve 2 is fixed with the same number of second blades and opposite positions as the first blades at equal intervals along the circumferential direction, and the second blades have the same shape as the first blades. After the second sleeve 2 and the third sleeve 3 are installed, the first blade fits the second blade. The outer wall of the second sleeve 2 is fixed with multiple evenly distributed scale lines 21. The outer wall of the third sleeve 3 is fixed with an indicator needle 31. When the indicator needle 31 is located at the scale line 21 on one side edge, the second blade is completely opposite to the first blade, which is the maximum wind pressure state; when the indicator needle 31 is located at the scale line 21 on the other side edge, the second blade and the first blade are completely staggered, which is the completely closed state of the pipeline. Rotating the second sleeve 2 can change the position of the first blade in the second sleeve 2, thereby changing the relative position of the first blade and the second blade, and further changing the wind pressure. The wind pressure regulating device has a simple structure and can quickly adjust the wind pressure.

[0033] Reference Figure 1 The outer walls of both ends of the second sleeve 2 are coated with a grease layer, and the specific material of the grease layer is lubricating oil. The grease layer is coated on the outer walls of both ends of the second sleeve 2 to reduce the friction between the second sleeve 2 and the first sleeve 1 and the third sleeve 3, so as to facilitate the rotation of the second sleeve 2. A paddle 22 is fixed on the outside of the second sleeve 2. The staff can drive the second sleeve 2 to rotate by paddle 22, so as to facilitate the rotation of the second sleeve 2, thereby facilitating the change of the wind pressure in the pipeline.

[0034] Reference Figure 1 , a plurality of first bosses 11 distributed in the circumferential direction are integrally formed on the outer side of the first sleeve 1. The first fixing assembly 4 is arranged at the first boss 11. The first fixing assembly 4 includes a first nut 41 and a first bolt 42. The first nut 41 is fixedly connected in the first boss 11 of the first sleeve 1. The first bolt 42 is threadedly connected in the first nut 41, and the first bolt 42 passes through the first sleeve 1 and abuts against the outer wall of the second sleeve 2. After the second sleeve 2 is rotated, rotating the first bolt 42 can fix the second sleeve 2 to the first sleeve 1, so that the second sleeve 2 will not rotate during the gas transportation process, and thus will not change the wind pressure, which is convenient for gas transportation.

[0035] Reference Figure 1 A dynamic pressure collector 6 is provided on the inner surface of the first sleeve 1. A hollow pressure pipe 7 is plugged into the first sleeve 1. The end of the pressure pipe 7 facing away from the dynamic pressure collector 6 is connected to an external pressure monitoring device. The specific wind pressure value in the pipeline can be known through the pressure monitoring device, which is convenient for accurate adjustment of the wind pressure.

[0036] Reference Figure 1, a plurality of second bosses 32 distributed in the circumferential direction are integrally formed on the outer side of the third sleeve 3. The second fixing assembly 5 is arranged at the second boss 32. The second fixing assembly 5 comprises a second nut 51 and a second bolt 52. The second nut 51 is fixedly connected in the second boss 32 of the third sleeve 3. The second bolt 52 is threadedly connected in the second nut 51, and the second bolt 52 passes through the third sleeve 3 and abuts against the outer wall of the second sleeve 2. After the second sleeve 2 is rotated, the second bolt 52 can be rotated to fix the second sleeve 2 and the third sleeve 3, so that the second sleeve 2 will not rotate during the gas transportation process, and thus the wind pressure will not be changed, which is convenient for gas transportation.

[0037] The implementation principle of a device for manually adjusting the wind pressure in a pipeline according to an embodiment of the present application is as follows: the first sleeve 1 and the third sleeve 3 are installed between two adjacent pipelines to achieve the installation of the device. Before adjusting the wind pressure, the first bolt 42 and the second bolt 52 are loosened so that the first bolt 42 and the second bolt 52 are separated from the outer wall of the second sleeve 2. After the first bolt 42 and the second bolt 52 are separated from the outer wall of the second sleeve 2, the paddle 22 is moved to drive the second sleeve 2 to rotate, and the degree of wind pressure adjustment can be judged according to the positional relationship between the indicator needle 31 and the scale line 21. Thus, rapid adjustment of wind pressure is achieved.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
