Description

Technical Field

[0001] This utility model relates to the field of fluid measurement equipment technology, specifically to a support housing for fixing and protecting flow meters. It is applicable to various types of liquid and gas flow meters, such as differential pressure flow meters, rotor flow meters, electromagnetic flow meters, and ultrasonic flow meters, and can be widely used in industries such as petroleum, chemical, water treatment, and energy that require fluid flow measurement. Background Technology

[0002] A flow meter is an instrument that indicates the measured flow rate and / or the total fluid volume within a selected time interval. Simply put, it is an instrument used to measure the flow rate of fluid in pipes or open channels. Based on different measurement principles, flow meters can be classified into differential pressure flow meters, rotor flow meters, throttling flow meters, slot flow meters, volumetric flow meters, electromagnetic flow meters, ultrasonic flow meters, etc.; according to the measured medium, they can also be classified into liquid flow meters and gas flow meters.

[0003] In practical applications, flow meters typically need to be connected to the pipe being measured and fixed by a support structure. However, existing flow meter support structures have significant shortcomings: Firstly, the flow meter and pipe are often rigidly connected. When there are external collisions, equipment vibrations, or water flow impacts within the pipe, the vibration and impact forces are directly transmitted to the connection between the pipe and the flow meter. Long-term use can easily lead to pipe cracks, loose connections, and other damage, affecting not only the flow meter's measurement accuracy but also potentially causing fluid leaks and posing safety hazards. Secondly, the components that limit the flow meter at both ends in existing support structures are mostly fixed structures, and their spacing cannot be adjusted according to the flow meter's length, diameter, or other specifications. When it is necessary to replace a flow meter of different specifications, a new, compatible support structure must be installed, increasing usage costs and reducing installation and maintenance flexibility, failing to meet diverse application needs. Utility Model Content

[0004] The purpose of this utility model is to provide a support housing for a flow meter to solve the problems of easy damage to the existing flow meter and pipeline hard connection and the non-adjustable spacing of the support structure.

[0005] The flow meter support housing includes a left limit seat and a right limit seat for fixing the flow meter, and also includes a spacing adjustment assembly disposed at the bottom of the left limit seat and the right limit seat. The bottom of the spacing adjustment assembly is provided with front-back and left-right shock absorption components.

[0006] Both the left and right limit seats have adjustable clamping assemblies on their inner sides. These assemblies include silicone elastic buffer pads fixed to the inner wall of the limit seats and telescopic limit baffles movably connected via adjusting bolts. The side walls of both the left and right limit seats have oblong adjusting holes, through which the adjusting bolts are threadedly connected to the telescopic limit baffles. The silicone elastic buffer pads are made of oil-resistant and aging-resistant silicone rubber, which increases friction with the outer wall of the flowmeter, improving clamping stability, and also acts as a buffer during vibration, preventing hard contact damage to the flowmeter.

[0007] The spacing adjustment assembly includes a support fixed to the top of the front, rear, left, and right shock absorbers. The support has a groove, and a spacing adjustment mechanism is installed inside the groove. The spacing adjustment mechanism includes a U-shaped support fixed inside the groove, with a screw rod connected to both ends of the U-shaped support via bearings, and a pair of guide rods for guidance. A geared motor is fixed to the right side wall of the support, and the rotor of the geared motor is fixedly connected to the screw rod. Left and right sliding cylinders are respectively sleeved on the left and right ends of the guide rods, and left and right threaded cylinders are respectively screwed to the left and right ends of the screw rods. A left T-block is fixed between the two left sliding cylinders and the left threaded cylinder, and a right T-block is fixed between the two right sliding cylinders and the right threaded cylinder. The top of the left T-block is fixedly connected to the bottom of the left limit seat, and the top of the right T-block is fixedly connected to the bottom of the right limit seat. The threads at the left and right ends of the screw are in opposite directions. The left and right threaded cylinders are screwed onto the threads at the left and right ends of the screw in different directions, ensuring that when the screw rotates, the left and right threaded cylinders can drive the left and right T-blocks to move in opposite directions along the guide rod.

[0008] The front, rear, left, and right shock absorption components include a mounting plate with oblong mounting holes for easy fixing of the support housing in different positions. Left and right swivel seats are movably mounted on the mounting plate, with springs installed at the bottom of both ends of each swivel seat. Rigid guide sleeves are fitted around the outside of the springs, with one end fixedly connected to the bottom of the swivel seat and the other end slidingly against the top of the mounting plate. The rigid guide sleeves prevent lateral displacement during spring extension and contraction, ensuring stability in the shock absorption direction. Front and rear swivel seats are movably mounted on the left and right swivel seats, with torsion springs mounted on their shafts. Torsion spring preload nuts are threaded to both ends of the shafts, with the torsion springs abutting against the preload nuts and the side walls of the front and rear swivel seats respectively. Adjusting the preload nuts changes the initial preload of the torsion springs, adapting to vibration environments of varying intensities. Polytetrafluoroethylene (PTFE) wear-resistant gaskets are provided on the contact surfaces of the left and right swivel seats and the front and rear swivel seats. PTFE has excellent wear resistance and a low coefficient of friction, reducing frictional loss during relative rotation and extending service life.

[0009] Spacing Adjustment Principle: When adjusting the spacing between the left and right limit seats according to the flowmeter length, start the geared motor (using a 42-stepper motor for high control precision) on the right side wall of the support. The rotor of the geared motor drives the screw to rotate around the bearing. Since the threads at the left and right ends of the screw are opposite in direction, and the left and right threaded cylinders are screwed into the threads at the left and right ends of the screw respectively, the rotation of the screw drives the left and right threaded cylinders to move in opposite or opposite directions along the screw axis. Simultaneously, the left sliding cylinder on the guide rod moves synchronously with the left threaded cylinder, and the right sliding cylinder moves synchronously with the right threaded cylinder. The guide rod acts as a guide, preventing the left and right T-blocks from rotating during movement. The left and right T-blocks then drive the left and right limit seats at the top to move synchronously until the spacing between the two limit seats matches the flowmeter length. Turning off the geared motor completes the spacing adjustment.

[0010] Adjustable clamping principle: Based on the flowmeter's diameter, first loosen the adjusting bolt. Since the adjusting bolt passes through the oblong adjusting hole, it can push the telescopic limit baffle to move along the length of the oblong adjusting hole inside the left or right limit seat. When the telescopic limit baffle contacts the outer wall of the flowmeter, the silicone elastic buffer pad is compressed and tightly adheres to the outer wall of the flowmeter. At this time, tighten the adjusting bolt to fix the telescopic limit baffle in its current position, thus clamping and fixing the flowmeter. If it is necessary to disassemble or replace the flowmeter, simply loosen the adjusting bolt and move the telescopic limit baffle; the operation is convenient.

[0011] Front-back and lateral vibration damping principle: When the support housing is subjected to lateral vibration (such as equipment vibration or external impact), the left and right rotating seats will displace relative to the mounting plate in the lateral direction. At this time, the springs at the bottom of both ends of the left and right rotating seats will be compressed or stretched accordingly. The elastic force of the springs will offset part of the vibration energy, reducing the impact of vibration on the flow meter and pipeline. The rigid guide sleeve moves synchronously with the left and right rotating seats, and its bottom slides against the top of the mounting plate to prevent the spring from bending laterally and ensure stable lateral vibration damping. When subjected to front-back vibration (such as vibration caused by fluid impact in the pipeline), the front and rear rotating seats will rotate around their axis relative to the left and right rotating seats in the front-back direction. The torsion spring on the axis will deform, and the elastic force of the torsion spring will offset part of the front-back vibration energy, achieving front-back vibration damping. If the vibration intensity of the operating environment changes, the initial compression of the torsion spring can be adjusted by rotating the torsion spring preload nuts at both ends of the axis to change the preload of the torsion spring and achieve the best vibration damping effect.

[0012] Compared with the prior art, the beneficial effects of this utility model are: Solving the problem of easy damage to hard links: The front, rear and left, right shock absorption components achieve shock absorption in both left and right and front and rear directions through springs and torsion springs. They can effectively absorb the energy generated by external collisions, equipment vibrations and water flow impacts, reduce the transmission of vibration to flow meters and pipelines, avoid damage such as pipeline cracks and loose interfaces, extend the service life of flow meters and pipelines, and ensure measurement accuracy and safety of use.

[0013] Enhanced support flexibility: The spacing adjustment component adjusts the spacing between the left and right limit seats via a geared motor-driven screw, adapting to flow meters of different lengths; the adjustable clamping component adapts to flow meters of different diameters via a movable telescopic limit baffle, eliminating the need to replace the support structure, reducing operating costs, and improving installation and maintenance flexibility.

[0014] Enhanced clamping stability and protection: The silicone elastic buffer pads in the adjustable clamping assembly not only increase the friction with the outer wall of the flow meter, improving clamping stability, but also prevent damage to the flow meter caused by hard contact; the PTFE wear-resistant pads reduce frictional losses between the front and rear rotors and the left and right rotors, extending the service life of the shock absorption assembly.

[0015] Easy to install and highly adaptable: The waist-shaped mounting holes on the mounting plate make it easy to fix the support housing in different positions to adapt to different installation environments; the torsion spring preload nut can adjust the torsion spring preload to adapt to vibration environments of different intensities, making it highly practical.

[0017] 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.

[0018] Example 1 like Figure 1 As shown; A support housing for a flow meter includes a left limiting seat 1 and a right limiting seat 2 for fixing the flow meter.

[0019] This implementation plan addresses the technical problems existing in the prior art, such as the significant shortcomings of the existing flow meter support structure disclosed in the background section above: On the one hand, the flow meter and the pipeline are mostly rigidly connected. When there is external collision, equipment vibration, or water flow impact in the pipeline, the vibration and impact force will be directly transmitted to the connection between the pipeline and the flow meter. Long-term use can easily lead to damage problems such as cracks in the pipeline and loosening of the interface, which not only affects the measurement accuracy of the flow meter but may also cause fluid leakage, posing a safety hazard. On the other hand, the components that limit the flow meter at both ends in the existing support structure are mostly fixed structures, and their spacing cannot be adjusted according to the length, diameter, and other specifications of the flow meter. When it is necessary to replace the flow meter with a different specification, a matching support structure must be replaced, which not only increases the cost of use but also reduces the flexibility of installation and maintenance, failing to meet diverse usage needs. In practical terms, this problem is obviously a real and difficult-to-solve issue. Therefore, to solve this technical problem, a support housing for the flow meter is provided.

[0020] like Figure 1-6 As shown in the figure; This embodiment provides a support housing for a flow meter, the structure of which is as follows: Figures 1 to 4As shown, it includes a left limit seat 1, a right limit seat 2, a spacing adjustment component 3, and a front-to-back and left-to-right shock absorption component 4. The left limit seat 1 and the right limit seat 2 are used to fix the flow meter. The spacing adjustment component 3 is set at the bottom of the left limit seat 1 and the right limit seat 2. The front-to-back and left-to-right shock absorption component 4 is set at the bottom of the spacing adjustment component 3.

The silicone elastic buffer pad 11 is fixed to the inner wall of the limit seat by adhesive. The side walls of the left limit seat 1 and the right limit seat 2 are provided with waist-shaped adjustment holes 14. The adjusting bolt 12 passes through the waist-shaped adjustment hole 14 and is threadedly connected to the telescopic limit baffle 13. The telescopic limit baffle 13 is made of stainless steel with a thickness of 3mm to ensure structural strength.

[0022] The spacing adjustment assembly 3 includes a support 31, a groove 32, and a spacing adjustment mechanism 33. The support 31 is fixed to the top of the front, rear, left, and right shock-absorbing assemblies 4 by bolts. The groove 32 on the support 31 has a depth of 50mm and a width that matches the U-shaped support 331. The U-shaped support 331 in the spacing adjustment mechanism 33 is fixed inside the groove 32 by welding. The bearings at both ends of the U-shaped support 331 are 6202 deep groove ball bearings. The screw 332 is made of 45# steel with a diameter of 12mm. The guide rod 333 is an 8mm diameter optical shaft that is interference-fitted with the U-shaped support 331. The geared motor is model 42BYGH4818 and is fixed to the right side wall of the support 31 by a motor bracket. Its rotor is fixedly connected to the screw 332 by a coupling. The inner diameters of the left slide cylinder 334 and the right slide cylinder 335 are clearance-fitted with the outer diameter of the guide rod 333. The internal threads of the left threaded cylinder 336 and the right threaded cylinder 337 are respectively adapted to the external threads at the left and right ends of the screw 332. The left T-block 338 and the right T-block 339 are made of aluminum alloy and are fixedly connected to the left slide cylinder 334, the left threaded cylinder 336, the right slide cylinder 335, and the right threaded cylinder 337 respectively by welding. The tops of the left T-block 338 and the right T-block 339 are fixedly connected to the bottoms of the left limit seat 1 and the right limit seat 2 respectively by bolts.

[0023] The front-rear and left-right shock absorption assembly 4 includes a mounting plate 41, left and right rotating seats 42, a spring 43, a front-rear rotating seat 44, and a torsion spring 45. The mounting plate 41 is made of Q235 steel plate with a thickness of 8mm, and its waist-shaped mounting hole is 50mm long and 12mm wide. The left and right rotating seats 42 are movably connected to the guide rails on the mounting plate 41 via sliders. The spring 43 is a cylindrical helical compression spring with a wire diameter of 3mm, an outer diameter of 20mm, and a free length of 40mm.

The torsion spring 45 is a cylindrical torsion spring with a wire diameter of 2mm and a middle diameter of 15mm. The torsion spring preload nut is an M8 hexagonal nut. The PTFE wear-resistant gasket is 1mm thick and is glued to the contact surface of the left and right rotating seats 42 and the front-rear rotating seat 44.

[0024] Installation and usage process Support housing fixing: Use expansion bolts to fix the entire support housing to the bracket or ground at the flow meter installation position through the waist-shaped mounting holes on the mounting plate 41. Adjust the fixing position of the mounting plate 41 according to the actual installation requirements to ensure the stability of the support housing.

[0025] Spacing adjustment: Based on the length of the flow meter to be installed, start the geared motor. The geared motor drives the screw 332 to rotate. The left threaded cylinder 336 and the right threaded cylinder 337 move in opposite directions along the screw 332, driving the left T-block 338, the right T-block 339, and the left limit seat 1 and the right limit seat 2 to move synchronously. When the spacing between the left limit seat 1 and the right limit seat 2 is consistent with the length of the flow meter, turn off the geared motor to complete the spacing adjustment.

[0026] Flowmeter clamping: Place the flowmeter between the left limit seat 1 and the right limit seat 2, loosen the adjusting bolt 12, push the telescopic limit baffle 13 so that the telescopic limit baffle 13 contacts the outer wall of the flowmeter. At this time, the silicone elastic buffer pad 11 is compressed and tightly adheres to the flowmeter. Tighten the adjusting bolt 12 to fix the telescopic limit baffle 13, thus completing the clamping and fixing of the flowmeter.

[0027] Vibration damping adjustment: Depending on the vibration intensity of the environment, rotate the torsion spring preload nuts at both ends of the front and rear swivels 44 to adjust the initial preload of the torsion spring 45, so that the vibration damping effect in the front and rear directions can be optimized; the vibration damping in the left and right directions is automatically achieved by the spring 43, without the need for additional adjustment.

[0028] Maintenance and Replacement: When the flow meter needs to be replaced, loosen the adjusting bolt 12, move the telescopic limit baffle 13, take out the old flow meter, put in the new flow meter, and repeat step 3; if the length specification of the new flow meter has changed, repeat step 2 to adjust the spacing before clamping and fixing.
