Description

Technical Field

[0001] This utility model relates to the field of fluid flow detection technology, and in particular to a flow detection device for processing high-sealing pipeline components. Background Technology

[0002] In the fields of mechanical engineering and fluid transmission, high-sealing pipe fittings are a type of pipe connection and adapter component with excellent leakage protection capabilities. Their core function is to effectively prevent the leakage of liquids, gases, powders, and other fluids from the pipeline under harsh operating conditions such as high pressure, high temperature, corrosion, and vibration, or in scenarios involving the transmission of volatile or toxic media. Simultaneously, they prevent external impurities such as air, moisture, and dust from entering the pipeline system, thereby ensuring the sealing, safety, and operational stability of the fluid transmission process. Conducting targeted sealing performance testing on the manufactured pipe fittings is a crucial step in verifying whether they meet design requirements and ensuring their reliable operation under actual working conditions.

[0003] Currently, some testing devices often lead to abnormal data, gas or liquid leaks during the testing of pipeline components because their sealing performance is lower than that of the pipeline components themselves. To address this, we propose a flow detection device for processing pipeline components with high sealing performance. Utility Model Content

[0004] The purpose of this invention is to provide a flow detection device for processing high-sealing pipe fittings, in order to solve the problem mentioned in the background art that some current detection devices often lead to abnormal data, gas or liquid leakage, etc. during the detection process because their sealing performance is lower than that of the pipe fittings.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flow detection device for processing high-sealing pipe fittings, comprising an electromagnetic flowmeter, which is composed of a sensor, an excitation coil, electrodes, etc. A sealing assembly and a buffer assembly are provided on the outside of the electromagnetic flowmeter. The sealing assembly includes two sets of flanges. A second sealing ring and a compression plate are fixedly connected to both ends of the electromagnetic flowmeter. A wave spring washer and a first sealing ring are fixedly connected to the ends of the second sealing ring and the compression plate away from the electromagnetic flowmeter, respectively. One end of the flange is fixedly connected to one end of the wave spring washer. A protective circular plate is fixedly connected to the end of the flange closest to the electromagnetic flowmeter.

[0006] As a preferred embodiment, the protective circular plate has an extrusion groove inside, the end of the first sealing ring away from the extrusion plate is fixedly connected to the bottom end of the extrusion groove, and the second sealing ring and the wave spring washer are located inside the protective circular plate.

[0007] As a preferred embodiment, the end of the flange furthest from the electromagnetic flowmeter is fixedly connected to multiple sets of circumferentially distributed fixing plates, one end of each fixing plate is fixedly connected to a hydraulic rod, and one end of the hydraulic rod is fixedly connected to the outside of the electromagnetic flowmeter.

[0008] As a preferred embodiment, the buffer assembly includes a base plate and four sets of connecting rods. A U-shaped plate is fixedly connected to the upper end of each connecting rod, and a compression spring and a guide rod are fixedly connected to the lower end of each connecting rod. A sliding plate is fixedly connected to the lower end of the compression spring and the guide rod. Slide grooves are provided on both the left and right sides of the upper end of the base plate.

[0009] As a preferred embodiment, the compression spring is sleeved on the outer circumferential surface of the guide rod, two sets of fixing rods are fixedly connected to the upper end of the base plate, the upper end of the fixing rods is fixedly connected to the outer circumferential surface of the electromagnetic flowmeter, and the slide plate is slidably connected in the slide groove.

[0010] As a preferred embodiment, a bidirectional threaded rod is threadedly connected to the lower part of the inner side of the connecting rod. The rear end of the bidirectional threaded rod is rotatably connected to the inner side wall of the slide groove, and the bidirectional threaded rod is movably connected to the inside of the base plate.

[0011] The technical effects and advantages of this utility model are as follows: The electromagnetic flowmeter forms a double sealing structure with the second sealing ring at both ends, the wave spring washer, and the first sealing ring. The compression groove of the protective circular plate compresses the first sealing ring. The internal motor of the electromagnetic flowmeter detects the flow rate and quality of the liquid and transmits the detected data to the converter, etc., to detect the quality and speed of the liquid flow, thereby improving the sealing performance at the connection and effectively preventing fluid leakage from affecting the detection accuracy. The circumferentially arrayed fixed plates and hydraulic rods work together to provide uniform and stable axial pressure, ensuring that the sealing components and pipeline parts fit tightly, further enhancing the sealing reliability. The base plate is securely connected to the electromagnetic flowmeter via a fixed rod. Four sets of connecting rods, together with a U-shaped plate, form a stable support structure. The compression spring and guide rod work together to effectively buffer the fluid impact and vibration during pipeline testing, improving the stability of the test data. The sliding fit between the slide plate and the groove, as well as the thread adjustment design of the bidirectional threaded rod, allows for flexible adjustment of the connecting rod spacing to adapt to the clamping and positioning requirements of different specifications of pipeline components. The buffer assembly as a whole, through the dual design of elastic buffering and adjustable positioning, reduces the impact of fluid pulsation on the testing accuracy and improves the adaptability of the device to different pipeline components.

[0014] 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.

[0015] Please see the appendix Figure 1 - Appendix Figure 4 A flow detection device for processing high-sealing pipeline components includes an electromagnetic flowmeter 1, which is composed of a sensor, an excitation coil, electrodes, etc. A sealing assembly 2 and a buffer assembly 3 are provided on the outside of the electromagnetic flowmeter 1. The sealing assembly 2 includes two sets of flanges 201. A second sealing ring 207 and a compression plate 205 are fixedly connected to both ends of the electromagnetic flowmeter 1. A wave spring washer 206 and a first sealing ring 204 are fixedly connected to the ends of the second sealing ring 207 and the compression plate 205 away from the electromagnetic flowmeter 1, respectively. One end of the flange 201 is fixedly connected to one end of the wave spring washer 206. A protective circular plate 202 is fixedly connected to the end of the flange 201 near the electromagnetic flowmeter 1. A compression groove 203 is opened inside the protective circular plate 202. The end of the first sealing ring 204 away from the compression plate 205 is fixedly connected to the bottom of the compression groove 203. The second sealing ring 207 and the wave spring washer 206 are located inside the protective circular plate 202.

[0016] The electromagnetic flowmeter 1 consists of a sensor, a converter, an excitation coil, and electrodes. The electromagnetic flowmeter uses the excitation coil and electrodes to detect the kinetic energy and mass of the fluid. The electrodes are used to detect the velocity of the flowing liquid. The converter converts electromagnetic induction into an electrical signal, which is then converted into a digital signal for processing. The processed digital signal is displayed on the screen. This technology is mature and will not be elaborated upon here. The wave spring washer 206 compensates for the deformation of the second sealing ring 207 caused by thermal expansion and contraction, preventing a weakening of the sealing effect due to deformation of the second sealing ring 207. The extrusion plate 205 and the first sealing ring 204 are pressed into the extrusion groove 203 opened in the protective circular plate 202. Since the size of the extrusion groove 203 is the same as the size of the extrusion plate 205, it further enhances the sealing effect in conjunction with the first sealing ring 204. The protective circular plate 202 protects the second sealing ring 207 and the wave spring washer 206 from damage caused by external factors.

[0017] The flange 201 is fixedly connected to a plurality of fixed plates 208 arranged in a circular pattern at the end away from the electromagnetic flowmeter 1. A hydraulic rod 209 is fixedly connected to one end of the fixed plate 208, and one end of the hydraulic rod 209 is fixedly connected to the outside of the electromagnetic flowmeter 1.

[0018] The fixed plate 208 and the hydraulic rod 209 work together to move the flange 201, causing the flange 201 to press against the aforementioned parts, which further increases the sealing effect. This makes the sealing performance of the connection between the electromagnetic flowmeter 1 and the pipeline component stronger than that of the pipeline component being tested, thus avoiding leakage at the connection point due to the lower sealing performance of the connection between the electromagnetic flowmeter 1 and the pipeline component during the testing process.

[0019] Specifically, during assembly, first fix the second sealing ring 207 and the extrusion plate 205 to the left and right ends of the electromagnetic flowmeter 1 respectively. Then connect the wave spring washer 206 to the second sealing ring 207 and the first sealing ring 204 to the extrusion plate 205. Subsequently, fit the second sealing ring 207 and the wave spring washer 206 onto the protective circular plate 202, and embed the first sealing ring 204 into the extrusion groove 203 to complete the assembly of the sealing component 2 with the main body. During testing, start the hydraulic rod 209, which drives the flange 201 to move axially through the fixing plate 208, so that the sealing component 2 and the pipe fitting port are tightly fitted. The hydraulic rod 209 provides stable axial pressure to ensure the sealing fit. The wave spring washer 206 compensates for the thermal expansion and contraction deformation of the second sealing ring 207. The extrusion plate 205 and the extrusion groove 203 work together to enhance the sealing effect of the first sealing ring 204. The protective circular plate 202 protects the internal sealing components, ensuring no leakage during the testing process and ensuring accurate flow and velocity detection data.

[0020] Please see the appendix Figure 5 and attached Figure 6The buffer assembly 3 includes a base plate 301 and four sets of connecting rods 303. A U-shaped plate 302 is fixedly connected to the upper end of the connecting rod 303, and a compression spring 304 and a guide rod 305 are fixedly connected to the lower end of the connecting rod 303. A sliding plate 306 is fixedly connected to the lower end of the compression spring 304 and the guide rod 305. Slide grooves 308 are provided on both the left and right sides of the upper end of the base plate 301.

[0021] The connecting rod 303 and the U-shaped plate 302 work together to clamp the connecting pipe. When the pipe is transporting liquid or gas, it will vibrate. The U-shaped plate 302 will transmit the force of the vibration to the connecting rod 303. The connecting rod 303 squeezes the compression spring 304 and the guide rod 305. The guide rod 305 not only plays a guiding role, but also extends and retracts together with the compression spring 304.

[0022] A compression spring 304 is sleeved on the outer circumferential surface of the guide rod 305. Two sets of fixing rods are fixedly connected to the upper end of the base plate 301. The upper end of the fixing rod is fixedly connected to the outer circumferential surface of the electromagnetic flowmeter 1. The slide plate 306 is slidably connected to the slide groove 308. A bidirectional threaded rod 307 is threadedly connected to the lower part of the inside of the connecting rod 303. The rear end of the bidirectional threaded rod 307 is rotatably connected to the inner side wall of the slide groove 308. The bidirectional threaded rod 307 is movably connected to the inside of the base plate 301.

[0023] The fixed rod connects the electromagnetic flowmeter 1 and the base plate 301. Rotating the bidirectional threaded rod 307 causes the connecting rod 303 and the parts on the connecting rod 303 to slide in the slide groove 308. The size of the slide groove 308 is designed to allow the connecting rod 303 to extend and retract when it is subjected to vibration, without obstructing the connecting rod 303. The two threads of the bidirectional threaded rod 307 are opposite to each other. Since the bidirectional threaded rod 307 moves within the base plate 301, it can not only rotate but also rise and fall with the connecting rod 303.

[0024] Specifically, the base plate 301 is securely connected to the electromagnetic flowmeter 1 via a fixing rod. During assembly, the compression spring 304 is fitted onto the outer circumference of the guide rod 305. The guide rod 305 and the compression spring 304 are then connected to the connecting rod 303 and the sliding plate 306 at their respective ends, and the sliding plate 306 is embedded into the slide groove 308. Finally, the bidirectional threaded rod 307 is threaded through the lower part of the four sets of connecting rods 303 and rotatably connected to the inner wall of the slide groove 308. In use, the bidirectional threaded rod 307 is rotated, and its reverse thread drives the two sets of connecting rods 303 to slide in opposite directions along the slide groove 308. The spacing of the U-shaped plates 302 is adjusted to match the specifications of the pipe fittings. When the pipe fittings vibrate, the U-shaped plates 302 transmit the vibration force to the connecting rods 303. The compression spring 304 elastically expands and contracts to absorb the vibration, the guide rod 305 ensures the stability of expansion and contraction, and the slide groove 308 provides space for the sliding plate 306 to slide, thus achieving the function of buffering and shock absorption.

[0025] The working principle of this utility model is as follows: This utility model is a flow detection device for processing high-sealing pipeline components. First, the sealing assembly 2 fixes the second sealing ring 207 and the compression plate 205 at both ends of the electromagnetic flowmeter 1. After connecting the wave spring washer 206 and the first sealing ring 204, the sealing component is fitted by the protective circular plate 202 and the first sealing ring 204 is embedded in the compression groove 203 to complete the assembly. The buffer assembly 3 connects the electromagnetic flowmeter 1 and the base plate 301 via the fixing rod. The guide rod 305, fitted with the compression spring 304, is connected to the connecting rod 303 and the sliding plate 306. After being embedded in the sliding groove 308, the bidirectional threaded rod 307 passes through the connecting rod 303 to complete the installation. Before testing, the bidirectional threaded rod 307 is rotated to adjust the spacing of the U-shaped plate 302 to adapt to the pipeline specifications. The start-up fluid... The pressure rod 209 pushes the flange 201 axially through the fixed plate 208, so that the sealing assembly 2 fits tightly with the pipeline port. The hydraulic rod 209 provides stable pressure to ensure the initial seal. During the test, the wave spring washer 206 compensates for the thermal expansion and contraction deformation of the second sealing ring 207. The extrusion plate 205 and the extrusion groove 203 work together to strengthen the sealing effect of the first sealing ring 204. The protective circular plate 202 protects the internal seals to prevent leakage. The pipeline vibration is transmitted to the connecting rod 303 through the U-shaped plate 302. The compression spring 304 elastically expands and contracts to absorb the vibration force. The guide rod 305 ensures the stability of expansion and contraction. The sliding plate 306 slides flexibly along the sliding groove 308 to adapt to the displacement and achieve buffering and shock absorption. Finally, the electromagnetic flowmeter 1 accurately detects the flow rate and velocity of the fluid in the pipeline in a leak-free and low-vibration environment.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
