[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 The utility model provides an embodiment: a gas ultrasonic flow meter rectifier, including a guide tube 1, a rectifier plate 2 is inserted at the left end of the inner wall of the guide tube 1, and a variety of rectifier holes are opened on the rectifier plate 2. The rectifier plate 2 plays a role in smoothing and stabilizing the gas flow. The inner wall of the rectifier plate 2 is provided with an assembly and disassembly component 3. The assembly and disassembly component 3 is convenient for assembling and disassembling the rectifier plate 2, so as to facilitate the replacement of the rectifier plate 2 with different apertures. The inner wall of the guide tube 1 is provided with a rectifier component 4. The rectifier component 4 reduces the resistance and turbulence of the gas flowing in the guide tube 1.

[0031] Reference Figure 2 and Figure 3 The rectifier assembly 4 includes a circular ring 41, a transition section 42 is fixedly connected to the left side of the circular ring 41, and the transition section 42 is prevented from falling off by the fixing effect of the transition section 42. An insert block 43 is fixedly connected to the top of the left side of the circular ring 41, and the insert block 43 is prevented from falling off by the fixing effect of the insert block 43. There are two groups of symmetrically distributed insert blocks 43. A slot 45 is opened on the right side of the guide tube 1, and there are two groups of symmetrically distributed slots 45.

[0032] Reference Figure 3 and Figure 4 The assembly and disassembly component 3 includes a wedge block 33, the back of which is elastically connected to the front inner wall of the rectifier plate 2 through a spring 32. Through the elastic force of the spring 32, the wedge block 33 always maintains a clamping effect with the clamping groove 36 when not affected by external force, thereby limiting the rectifier plate 2. A clamping groove 36 is provided on the left side of the guide tube 1.

[0033] Reference Figure 1 and Figure 2The outer wall of the transition section 42 is plugged into the inner wall of the guide tube 1. By plugging the transition section 42 into the guide tube 1, the transition section 42 can be installed in the guide tube 1. The outer wall of the plug block 43 is plugged into the inner wall of the slot 45. The inner wall of the transition section 42 is streamlined. By setting the transition section 42 to be streamlined, the resistance and turbulence during gas flow can be reduced, making the gas flow more stable and uniform, thereby improving the rectification effect.

[0034] Reference Figure 2 and Figure 3 The inner wall of the right top of the guide tube 1 is threadedly connected with a bolt 44, and the outer wall of the bolt 44 is threadedly connected to the inner wall of the plug block 43. By screwing the bolt 44, the bolt 44 and the plug block 43 are threadedly connected or released, thereby limiting or releasing the limiting effect of the plug block 43.

[0035] Reference Figure 3 and Figure 4 An arc groove 35 is provided at the left end of the inner wall of the guide tube 1, and two groups of arc grooves 35 are symmetrically distributed. An elastic gasket 34 is fixedly connected to the inner wall of the arc groove 35, and two groups of elastic gaskets 34 are symmetrically distributed. The elastic gasket 34 is squeezed by the outer wall of the rectifier plate 2 and the inner wall of the arc groove 35, so that the elastic gasket 34 expands and deforms, thereby sealing the gap between the rectifier plate 2 and the guide tube 1, so that the left side of the rectifier plate 2 is fixedly connected with a handle 31, which makes it convenient for the staff to take the rectifier plate 2.

[0036] Reference Figure 4 One end of the spring 32 is fixedly connected to the front inner wall of the rectifier plate 2, and the other end of the spring 32 is fixedly connected to the back side of the wedge block 33. The fixing effect of the spring 32 keeps the wedge block 33 fixed to prevent the wedge block 33 from falling off. The outer wall of the wedge block 33 is slidably connected to the front inner wall of the rectifier plate 2. The sliding effect of the wedge block 33 allows the wedge block 33 to be engaged or released from the slot 36. The outer wall of the wedge block 33 is engaged with the inner wall of the slot 36. The engagement effect of the wedge block 33 and the slot 36 allows the guide tube 1 to limit the rectifier plate 2.

[0037] Working principle: When the staff needs to use the rectifier for rectification, the staff uses the handle 31 to insert the rectifier plate 2 into the left inner wall of the guide tube 1, so that the wedge block 33 is engaged with the slot 36 under the elastic force of the spring 32, and the rectifier plate 2 is limited at the same time. The elastic gasket 34 is squeezed by the rectifier plate 2 and the arc groove 35, so that the elastic gasket 34 expands and deforms, thereby sealing the gap between the rectifier plate 2 and the guide tube 1, so that the rectifier plate 2 remains fixedly installed on the guide tube 1.

[0038] The staff inserts the transition section 42 into the right inner wall of the guide tube 1, so that the plug block 43 is inserted into the inner wall of the slot 45. The staff tightens the bolt 44 and limits the plug block 43 at the same time, so that the transition section 42 remains fixedly installed inside the guide tube 1, thereby reducing the resistance and turbulence during gas flow and improving the rectification effect of the rectifier.

[0039] When it is necessary to replace the rectifier plate 2 with a different aperture, the staff presses the wedge block 33 so that the wedge block 33 releases the clamping effect with the slot 36 and releases the limiting effect on the rectifier plate 2. The staff uses the handle 31 to take out the rectifier plate 2 to facilitate disassembly and replacement of the rectifier plate 2.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
