Description

Technical Field

[0001] This utility model relates to the field of fluid flow measurement technology, specifically to an anti-reverse orifice plate lifting auxiliary device for a flange pressure tapping device. Background Technology

[0002] A flange pressure tap is a device used to measure the pressure or flow rate of fluid in a pipeline. Based on the principle of throttling, when fluid flows through the orifice plate in the pipeline, the flow stream locally contracts at the throttling point, increasing the flow velocity and decreasing the static pressure, creating a pressure drop (pressure difference) before and after the throttling point. The flow rate is measured by measuring this pressure difference, and the flange pressure tap is the component used to obtain this pressure difference. During use, the orifice plate needs to be periodically removed for a comprehensive inspection to check for manufacturing defects, improper installation, etc. Simultaneously, the orifice plate can be sent to a professional institution for calibration to ensure that its dimensional accuracy, throttling coefficient, and other parameters meet standard requirements, thus guaranteeing the accuracy and reliability of flow measurement.

[0003] A search revealed that Chinese Patent Publication No. CN218496171U discloses a flange pressure tapping flow measurement device, comprising a first flange and a second flange. Both the first and second flanges have a central hole in their center, and grooves are formed on adjacent sides of both flanges, with a standard orifice plate body held within each groove. This invention includes a first flange, a second flange, and a standard orifice plate body. The first and second flanges are rotatably connected on one side by a hinge. The standard orifice plate body is fitted inside the first and second flanges. The inner wall of the groove on the adjacent side of the first and second flanges for fixing the standard orifice plate body has two concentric annular grooves, each containing a sealing ring to improve the sealing performance of the connection between the standard orifice plate body and the first and second flanges. Furthermore, the second and first flanges, on the side away from the hinge, share a quick-clamping structure, allowing for rapid assembly of the first and second flanges.

[0004] However, this device also has the following drawbacks:

[0005] Existing technology requires disassembling the entire device when removing the orifice plate body, which is quite troublesome. Especially after the flange pressure tapping device is installed and fixed to the pipeline on both sides, the difficulty of disassembly and assembly is further increased. This device does not solve this problem. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Please see Figures 1-5 This utility model provides a technical solution:

[0028] An anti-reverse orifice plate lifting auxiliary device for a flange pressure tapping device includes a first flange 1 and a second flange 2. The inner sides of the first flange 1 and the second flange 2 are provided with mounting grooves 3, and the top of the mounting grooves 3 is provided with openings. Multiple sets of mounting holes 4 are provided on the sides and bottom of the first flange 1 and the second flange 2. The top of the first flange 1 is provided with a first pressure tapping hole 15, and the top of the second flange 2 is provided with a second pressure tapping hole 16.

[0029] By setting the first flange 1 and the second flange 2, it is easy to fix the orifice plate body 5 and also easy to connect with external pipelines. By setting the mounting groove 3, it is easy to limit the orifice plate body 5. By setting the opening at the top of the mounting groove 3, it is easy to remove the orifice plate body 5. By setting the first pressure tapping hole 15 and the second pressure tapping hole 16, the pressure on both sides of the orifice plate body 5 can be collected, thereby making it easy to determine the fluid flow rate.

[0030] It also includes an orifice plate body 5, which is disposed between the first flange 1 and the second flange 2. The orifice plate body 5 is slidably installed between two sets of mounting grooves 3. A first sealing ring 10 is provided between the first flange 1 and the orifice plate body 5, and the first sealing ring 10 is bonded to one side of the orifice plate body 5. A second sealing ring 11 is provided between the second flange 2 and the orifice plate body 5, and the second sealing ring 11 is bonded to the other side of the orifice plate body 5. Multiple sets of through holes 17 are opened on the surface of the orifice plate body 5. The opening of one side of the through hole 17 is larger than the opening of the other side. The fixing block 8 is fixedly connected to the top of the other side of the orifice plate body 5.

[0031] By creating through holes 17 on the surface of the orifice plate body 5, and making the opening on one side of the through hole 17 larger than the opening on the other side, a pressure difference can be formed on both sides of the orifice plate body 5 when the fluid passes through it. The fluid flow rate can be calculated from the pressure difference. By setting a first sealing ring 10 and a second sealing ring 11 on both sides of the orifice plate body 5, the sealing performance of the device can be improved, thereby preventing fluid leakage and further ensuring the accuracy of the measurement. By setting a fixing block 8 on the top of the orifice plate body 5, the two sides of the orifice plate body 5 can be distinguished, preventing the orifice plate body 5 from being reversed during installation, thereby ensuring the accuracy of the measurement data.

[0032] It also includes a lifting assembly, which includes a lifting block 6, which is slidably installed in the adjusting groove 7. The lifting block 6 abuts against the bottom of the fixed block 8. One side of the lifting block 6 is threadedly connected to the threaded rod 9. The adjusting groove 7 is opened on the inner side above the second flange 2. An mounting plate 12 is fixedly installed on one side of the top of the adjusting groove 7. The bottom of the threaded rod 9 is rotatably connected to the bottom of the adjusting groove 7. The threaded rod 9 and the mounting plate 12 are rotatably engaged. A fixed seat 13 is fixedly installed on the top of the threaded rod 9. A rotating rod 14 is fixedly installed on the top of the fixed seat 13.

[0033] By setting the rotating rod 14 and the fixed seat 13, it is easy to drive the threaded rod 9 to rotate. The rotating threaded rod 9 can make the lifting block 6 move upward, thereby driving the fixed block 8 and the orifice plate body 5 to move upward, making it easy for the operator to take out the orifice plate body 5. Moreover, it is not necessary to disassemble the first flange 1 and the second flange 2, which greatly improves the efficiency of taking out the orifice plate body 5 and reduces the difficulty of the work.

[0034] In practical use, move the device to the designated position, align the first flange 1 and the second flange 2 with the flanges of the pipes on both sides, and then use bolts to pass through the pipe flange, the first flange 1, the second flange 2 and the other pipe flange in sequence, ensuring that the lifting block 6 is at the bottom. Then move the orifice plate body 5, align the fixing block 8 on one side of the orifice plate body 5 with the adjusting groove 7 and insert the orifice plate body 5 downward into the bottom of the mounting groove 3. Then tighten the bolts in sequence to clamp the orifice plate body 5 in the mounting groove 3. When it is necessary to remove the orifice plate body 5, use external tools to loosen the bolts in sequence to loosen the orifice plate body 5. Then use the rotating rod 14 to rotate the fixing seat 13. The fixing seat 13 drives the threaded rod 9 to rotate, causing the lifting block 6 to move upward. The lifting block 6 abuts against the bottom of the fixing block 8 and drives it to rise together. The fixing block 8 drives the orifice plate body 5 to move upward, making it easy for the operator to remove.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
