Description

Technical Field

[0001] This utility model belongs to the field of vortex flow meter technology, specifically a vortex flow meter with an anti-vibration structure. Background Technology

[0002] A vortex flow meter is an instrument that uses the Karman vortex street principle to measure the volumetric flow rate of fluids (gas, liquid, steam). It features no moving parts, high pressure and high temperature resistance, and a wide range. It is widely used in industries such as petroleum, chemical, and energy. The two ends of the vortex flow meter are usually connected to the pipeline. The vortex flow meter is installed between the pipelines to detect the flow rate of gas, liquid, or steam in the pipeline.

[0003] In the existing technology, vortex flow meters are often used in scenarios where pipeline vibration is frequent (such as pump stations and compressor outlets). Therefore, during the use of vortex flow meters, they will vibrate with the vibration of the pipeline, which will affect the accuracy of the measurement results of the vortex flow meter and may even cause damage to it. Summary of the Invention

[0004] The purpose of this invention is to provide a vortex flowmeter with an anti-vibration structure, which plays an anti-vibration role during use, improves the accuracy of measurement results, and prevents the invention from being damaged by collision.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A vortex flowmeter with an anti-vibration structure is provided, comprising a flowmeter body, a support base, and a clamping plate. Two support bases are provided, symmetrically arranged on the lower surface of the flowmeter body. The inner walls of the two support bases are in contact with the outer wall of the flowmeter body. Mounting brackets are installed on the outer walls of the two support bases. Dampers are fixedly connected to both sides of the lower surface of the support base. The telescopic ends of the dampers are fixedly connected inside the mounting brackets. A first shock-absorbing pad is fixedly connected to the inner wall of the mounting bracket. The telescopic ends of the dampers are fixedly connected inside the first shock-absorbing pad. A first spring is sleeved on the outer wall of the dampers. A shock-absorbing plate is fixedly connected to the inner wall of the mounting bracket and is positioned directly below the support base. A second shock-absorbing pad is fixedly connected inside the mounting bracket and is positioned on both sides of the upper surface of the support base. Bolts are fixedly connected to both sides of the upper surface of the support base, and nuts are threaded onto the outer walls of the bolts.

[0006] Optionally, one end of the spring is fixedly connected to the inside of the support base, the other end of the spring is fixedly connected to the inside of the mounting bracket, and the bolt is slidably connected to the inside of the shock-absorbing pad and the mounting bracket.

[0007] Optionally, two clamping plates are provided, each clamping plate is disposed on the upper surface of the two support seats, and the inner walls of the two clamping plates are in contact with the outer wall of the flow meter body.

[0008] Optionally, a first locking block is slidably connected inside the clamping plate and is slidably connected inside the support base; a second locking block is slidably connected inside the clamping plate and is slidably connected inside the support base.

[0009] Optionally, a sliding pin is fixedly connected to the outer wall of the first clamping block, and the sliding pin is limited to slide inside the clamping plate. A sliding pin is fixedly connected to the outer wall of the second clamping block, and the sliding pin is limited to slide inside the clamping plate.

[0010] Optionally, a second spring is sleeved on the outer wall of the sliding pin one, one end of the second spring is fixedly connected to the inside of the clamping plate, and the other end of the second spring is fixedly connected to the inside of the sliding pin one.

[0011] Optionally, a spring three is sleeved on the outer wall of the sliding pin two, one end of the spring three is fixedly connected to the inside of the clamping plate, and the other end of the spring three is fixedly connected to the inside of the sliding pin two.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model installs the flow meter body between pipes to detect the flow rate of gas, liquid, or steam in the pipes. When the pipe vibrates, the flow meter body vibrates accordingly, causing the support base to swing up and down, which in turn causes the damper to extend and retract. Combined with the automatic reset action of the spring and the damper, the support base is reset. During the up-and-down swing of the support base with the flow meter body, the lower surface of the support base contacts the damping plate, which assists in the reset of the support base. When the support base swings upward, the damping pad 2 cushions the support base, assisting in its automatic reset. The bolts and nuts can adjust the distance of the cushioning reset, thus providing a cushioning reset effect for the flow meter body, reducing the vibration of the flow meter body, improving the accuracy of the measurement results, and preventing damage to this utility model due to collisions.

[0014] 2. This utility model uses clamping plates symmetrically placed on the upper surface of the support base to clamp and fix the flow meter body. While placing the clamping plates on the upper surface of the support base, pressing the first and second locking blocks causes them to slide towards the center of the clamping plates, allowing them to be inserted into the support base. At this time, the lower surface of the clamping plate is in contact with the upper surface of the support base. Releasing the first and second locking blocks causes the second and third springs to automatically reset and lock them into the support base for limiting and fixing the clamping plates and the support base. This design effectively clamps the flow meter body and facilitates the disassembly and assembly of the support base and mounting bracket. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] The present invention will now be described. A vortex flowmeter with an anti-vibration structure includes a flowmeter body 1, a support base 2, and a clamping plate 11. The support base 2 and the clamping plate 11 are used to clamp and fix the flowmeter body 1. Two support bases 2 are provided, symmetrically arranged on the lower surface of the flowmeter body 1. The inner walls of the two support bases 2 are in contact with the outer wall of the flowmeter body 1. Mounting brackets 3 are installed on the outer walls of the two support bases 2. Dampers 4 are fixedly connected to both sides of the lower surface of the support base 2. The telescopic ends of the dampers 4 are fixedly connected to the inside of the mounting brackets 3. A shock-absorbing pad 5 is fixedly connected to the inner wall of the mounting brackets 3. The shock-absorbing pad 5 is used to protect the dampers 4 during the downward telescopic movement, preventing the dampers 4 from being damaged by impacts due to up-and-down shaking. It can also provide auxiliary buffering and reset for the dampers 4. The telescopic ends of the dampers 4 are fixedly connected to the inside of the shock-absorbing pad 5. A spring 6 is sleeved on the outer wall of the dampers 4. The spring 6 is used to buffer and self-dampate the dampers 4. The mounting bracket 3 has a shock-absorbing plate 7 fixedly connected to its inner wall. The shock-absorbing plate 7 is located directly below the support base 2. The shock-absorbing plate 7 protects the lower surface of the support base 2 to prevent the support base 2 from impacting the mounting bracket 3 when it moves downward. It also buffers the support base 2 and automatically resets it. The mounting bracket 3 has a shock-absorbing pad 8 fixedly connected inside. The shock-absorbing pad 8 is located on both sides of the upper surface of the support base 2. The shock-absorbing pad 8 can buffer and dampen the support base 2 when it moves upward, preventing the support base 2 from being impacted when it moves upward. The upper surface of the support base 2 is fixedly connected to both sides of the support base 2. The outer wall of the bolt 9 is threaded with a nut 10. By adjusting the position of the nut 10, the up and down sway and buffer distance of the support base 2 can be limited. One end of the spring 6 is fixedly connected to the inside of the support base 2, and the other end of the spring 6 is fixedly connected to the inside of the mounting bracket 3. The bolt 9 is slidably connected to the inside of the shock-absorbing pad 8 and the mounting bracket 3.

[0026] The present invention provides a vortex flowmeter with an anti-vibration structure. Compared with the prior art, by setting a buffer structure, the flowmeter body 1 is prevented from vibrating violently with the vibration of the pipeline during use, thereby improving the accuracy of the measurement results and preventing the present invention from being damaged by collision.

[0027] Please refer to another embodiment of this utility model as well. Figures 1 to 4Two clamping plates 11 are provided, each set on the upper surface of one of the two support bases 2. The inner walls of the two clamping plates 11 are in contact with the outer wall of the flowmeter body 1. A locking block 12 is slidably connected inside the clamping plate 11 and is slidably connected inside the support base 2, limiting its sliding within the clamping plate 11 and the support base 2. A locking block 15 is slidably connected inside the clamping plate 11 and is slidably connected inside the support base 2, limiting its sliding within the clamping plate 11 and the support base 2. A sliding pin 13 is fixedly connected to the outer wall of the locking block 12, limiting its sliding within the clamping plate 11. The outer wall of the second locking block 15 is fixedly connected to the second sliding pin 16, which limits the sliding within the clamping plate 11. The outer wall of the first sliding pin 13 is fitted with the second spring 14, one end of which is fixedly connected to the inside of the clamping plate 11, and the other end of which is fixedly connected to the inside of the first sliding pin 13. The second spring 14 automatically resets the first sliding pin 13 and the first locking block 12. The outer wall of the second sliding pin 16 is fitted with the third spring 17, one end of which is fixedly connected to the inside of the clamping plate 11, and the other end of which is fixedly connected to the inside of the second sliding pin 16. The third spring 17 automatically resets the second sliding pin 16 and the second locking block 15.

[0028] Working principle: In use, first install the flow meter body 1 between the pipes, then attach the support base 2 and the mounting bracket 3 to the lower surface of the flow meter body 1. Place the two clamping plates 11 symmetrically with the two support bases 2, and make the inner wall of the clamping plates 11 fit against the outer wall of the flow meter body 1. After aligning the clamping plates 11 with the support bases 2, press the first clamping block 12 and the second clamping block 15 to slide the first clamping block 12 and the second clamping block 15 towards the middle of the clamping plate 11. Then move the first clamping block 12 and the second clamping block 15 further. After spring 15 is inserted into the support base 2, it is released. Upon release, the elasticity of springs 14 and 17 causes locking blocks 12 and 15 to automatically reset and engage inside the support base 2 for limiting. This limits and fixes the clamping plate 11 and the support base 2, clamping them to the outer wall of the flowmeter body 1, completing the installation between the clamping plate 11, the support base 2, and the mounting bracket 3. Then, a support platform is placed at the bottom of the mounting bracket 3, with the support platform in contact with the ground. The mounting bracket 3 and the support platform... The flowmeter body 1 is fixed in place by screws or other structures. During use, the flowmeter body 1 will vibrate synchronously due to the vibration of the pipeline, causing it to sway up and down. This, in turn, causes the support base 2 to slide up and down, allowing the damper 4 to extend and retract, automatically resetting the support base 2. Simultaneously, the damper 4 will compress the spring 6, which also automatically resets the support base 2. When the support base 2 sways upward, the shock-absorbing pad 8 will cushion the support base 2, assisting in its automatic reset. The shock-absorbing pad 5 will cushion the damper 4's main body during downward movement, preventing damage from impact. Furthermore, when adjusting the buffer distance of the support base 2, the height can be adjusted by rotating the nut 10, changing the distance between the nut 10 and the mounting bracket 3. This limits the buffer distance of the support base 2, preventing excessive swaying of the support base 2 from causing severe shaking of the flowmeter body 1 and affecting the accuracy of the measurement results.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
