Description

Technical Field

[0001] This utility model relates to the field of instrumentation technology, specifically to a support tube connection structure for an ultrasonic flow meter. Background Technology

[0002] To achieve the "dual carbon goals," the country is making great efforts to control carbon emissions and increase carbon absorption. Both of these aspects require the measurement of carbon emissions, making the measurement methods, accuracy, and suitable instruments very important.

[0003] Currently, most flow meters on the market use a probe inserted into the chimney to transmit basic data. However, this method requires the probe to be extended to create a "cantilever" structure. When the probe reaches a considerable length, the high velocity of the flue gas causes the flow meter to vibrate at high frequencies, resulting in insufficient support at the base of the flow meter. This leads to a decrease in fatigue life and ultimately damage to the flow meter, rendering it unusable for extended periods. Utility Model Content

[0004] This utility model provides a support tube connection structure for an ultrasonic flow meter, which has the beneficial effect of improving the installation strength of the flow meter. It solves the problem mentioned in the background art that when the insertion rod reaches a long length, the entire flow meter will have high-frequency vibration of up and down swinging under the action of high flue gas velocity, resulting in insufficient support strength for the root of the flow meter, thus leading to a decrease in fatigue life, and ultimately causing the flow meter to be damaged and unable to be used for a long time.

[0005] This utility model provides the following technical solution: a support tube connection structure for an ultrasonic flow meter, including a plug rod for fixing the ultrasonic flow meter, a connecting component provided on the outer wall of the plug rod, and a sealing element provided at the connection position between the connecting component and the plug rod.

The support steel pipe is made of stainless steel, and the second support block is made of stainless steel.

[0007] As an optional solution of the support pipe connection structure for an ultrasonic flow meter described in this utility model, a boss is provided on one side of the second support block, a first through hole is opened in the flange, the boss is inserted into the first through hole, and the first through hole and the boss are welded together.

[0008] As an optional solution for the support pipe connection structure for an ultrasonic flow meter described in this utility model, a clamp is welded to one side of the second support block.

[0009] As an optional solution of the support tube connection structure for an ultrasonic flow meter described in this utility model, the sealing element is disposed between the first support block and the insertion rod, the sealing element includes a bushing, the first support block has a second through hole, and the bushing is fitted between the second through hole and the insertion rod.

[0010] As an optional solution for the support pipe connection structure for an ultrasonic flow meter described in this utility model, the bushing cross-section is T-shaped, and the outer ring of the bushing is fitted to the inner wall of the support steel pipe.

[0011] As an optional solution for the support pipe connection structure for an ultrasonic flow meter described in this utility model, an annular groove is provided on one side of the flange, a sealing ring is installed in the annular groove, and an arc-shaped through groove is provided inside the flange.

[0012] This utility model has the following beneficial effects: This is a support pipe connection structure for ultrasonic flow meters. By sequentially setting a flange, a first support block, and a second support block, the first support block is welded to the inner wall of the support steel pipe, the second support block is welded to the inner wall of the flange, and the flange is connected to one end of the support steel pipe. This effectively increases the contact area between the support pipe and the insertion rod, which solves the rigidity problem of the flange point cantilever support and alleviates the damage to the product caused by high-frequency vibration under airflow. This is a support pipe connection structure for ultrasonic flow meters. By setting a bushing, the bushing is connected between the support steel pipe and the insertion rod, which increases the toughness and provides support, protecting the insertion rod from metal wear by the support block and screws during vibration.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0020] Please see Figures 2 to 5 This utility model discloses a support pipe connection structure for an ultrasonic flow meter. The support pipe connection structure for an ultrasonic flow meter includes an insertion rod 2 for fixing the ultrasonic flow meter. The outer wall of the insertion rod 2 is provided with a connection component. The connection component includes a support steel pipe 3. A first support block 6 and a second support block 8 are respectively provided at both ends of the support steel pipe 3. The support steel pipe 3 is made of stainless steel.

[0021] In this embodiment, a support pipe connection structure for an ultrasonic flow meter is provided, including a connection assembly connected to the insertion rod 2, specifically including a support steel pipe 3 and a first support block 6 and a second support block 8 connected to both ends of the support steel pipe 3. In actual use, the outer diameter of the support steel pipe 3 is determined by the size of the sampling port opened on the surface of the chimney, and the support steel pipe 3 is preferably made of corrosion-resistant 316 stainless steel. At the same time, the length of the support steel pipe 3 is greater than the thickness of the chimney pipe wall, so that the entire support steel pipe 3 is inserted into the sampling port and fits snugly against the sampling port, thereby enhancing the support strength of the entire ultrasonic flow meter.

[0022] The second support block 8 has a boss 12 on one side, and a first through hole 11 is opened in the flange 4. The boss 12 is inserted into the first through hole 11, and the first through hole 11 and the boss 12 are welded together. The second support block 8 is made of stainless steel.

[0023] Specifically, the second support block 8 is preferably made of 316 stainless steel. By providing a boss 12 on one side of the second support block 8, which is inserted into the first through hole 11, the second support block 8 is welded to the flange 4 as a whole, thereby increasing the connection strength between the flange 4 and the support steel pipe 3 and enhancing the stability of the connection assembly.

[0024] An annular groove is provided on one side of flange 4, and a sealing ring 5 is installed in the annular groove. An arc-shaped through groove 14 is also provided inside flange 4.

[0025] It should be noted that, in order to accommodate situations where the bolt hole distribution is inconsistent on site, an arc-shaped through groove 14 is provided inside the flange 4, which is more adaptable. The groove for installing the sealing ring 5 adopts an anti-detachment design for easy installation.

[0026] A clamp 9 is welded to one side of the second support block 8. The clamp 9 is preferably made of 316 stainless steel and is locked by screws and insert rods 2. In order to prevent loosening during use, the opening of the clamp 9 and the clamp 9 are welded together with the second support block 8 to further enhance the stability of the connection component.

[0027] A sealing element is provided at the connection position between the connecting component and the insertion rod 2. The sealing element is located between the first support block 6 and the insertion rod 2. The sealing element includes a bushing 7. A second through hole 13 is opened in the first support block 6. The bushing 7 is fitted between the second through hole 13 and the insertion rod 2. The bushing 7 has a T-shaped cross section, and the outer ring of the bushing 7 is fitted with the inner wall of the support steel pipe 3.

[0028] In this embodiment, a second through hole 13 is provided in the first support block 6, and the bushing 7 is set as a T-shaped structure to increase the connection area between the first support block 6 and the bushing 7. First, the first support block 6 and the bushing 7 are fixed with screws and then inserted into the support steel pipe 3. They are then welded flush with one end of the support steel pipe 3. At the same time, the screws used to fix the bushing 7 are welded together with the first support block 6 to prevent the screws from loosening due to vibration.

[0029] It should be noted that the first support block 6 can increase the rigidity of the steel pipe against vibration, and the bushing 7 is made of polytetrafluoroethylene. The toughness and wear resistance of this material are used to protect the insertion rod 2 and prevent the metal from being damaged by the up-and-down vibration under high flow rate. At the same time, it also plays the role of floating support and reduces the hard friction between the support steel pipe 3 and the chimney sampling port.
