Description

Technical Field

[0001] This utility model relates to the field of electromagnetic flowmeter technology, specifically to a flange-type electromagnetic flowmeter capable of monitoring end-face leakage. Background Technology

[0002] Electromagnetic flow meters are commonly used measuring devices in industrial production and numerous fluid metering fields to accurately obtain fluid flow data. Traditional flange-type electromagnetic flow meters typically consist of a measuring conduit, measuring electrodes, an excitation coil, a magnetic circuit system, a housing, and a converter. They measure fluid flow through the principle of electromagnetic induction and are widely used in industries such as chemical engineering, water treatment, and food processing.

[0003] However, traditional flange-type electromagnetic flowmeters have a significant problem in practical use. Since the flange and connecting pipe are connected by bolts and other components, after long-term operation, factors such as fluid impact, temperature changes, and vibration can easily cause end-face leakage at the joint between the flange and the connecting pipe. Once leakage occurs, it not only wastes fluid and increases production costs but also may pollute the surrounding environment. If the leaked fluid is corrosive or toxic, it may even cause safety accidents. Traditional flange-type electromagnetic flowmeters lack end-face leakage monitoring capabilities, making it difficult to detect leaks in a timely manner and hindering timely repairs, causing numerous inconveniences and potential risks to production. Therefore, this paper proposes a flange-type electromagnetic flowmeter solution capable of monitoring end-face leakage. Utility Model Content

[0004] The purpose of this utility model is to provide a technical solution for a flange-type electromagnetic flowmeter capable of monitoring end-face leakage, thereby addressing the shortcomings mentioned in the background art. To overcome the drawbacks and defects described in the background art, this technical solution includes the following: a flowmeter with inlet and outlet ports connected to the left and right sides of its bottom; and an end-face leakage monitoring component is wrapped around the outer surface of each inlet and outlet port. The inlet and outlet ports include a flow meter interface fixedly connected to the flow meter port, and a flange fixed on the port of the flow meter interface away from the flow meter. A connecting pipe is connected to the outside of the flange, and multiple screws pass through the connecting pipe and the flange. Nuts are screwed onto the outer thread section of each screw.

[0005] The end-face leakage monitoring component includes two plastic collars, a nano-sponge ring embedded in the inner surface of the plastic collars, and multiple absorbent cotton rods fixed to the outer surface of the nano-sponge rings and arranged in a ring array. The outer ends of the absorbent cotton rods are all fixed with wood fiber blocks.

[0006] As a preferred embodiment of this utility model, the flow meter consists of a measuring conduit, measuring electrodes, an excitation coil, a magnetic circuit system, a housing, and a converter.

[0007] As a preferred embodiment of this utility model: a ring groove is formed on the inner surface of the plastic collar for the nano sponge ring to be embedded.

[0008] As a preferred embodiment of this utility model: the outer surface of the nano-sponge ring is fixedly connected to the inner surface of the annular groove inside the outer plastic sleeve, and the remaining segments of the nano-sponge ring are inserted into the annular groove inside the inner plastic sleeve for coupling.

[0009] As a preferred embodiment of this utility model: grooves are formed on the outer surface of the wood fiber block, and the inside of the grooves is filled with moisture-sensitive ink. The moisture-sensitive ink changes color after sensing liquid to indicate end-face leakage.

[0010] As a preferred embodiment of this utility model, multiple arc-shaped magnets are embedded and fixed on the end faces of the plastic collar and the through hole that are in close contact with each other.

[0011] As a preferred embodiment of this utility model, the outer ring of the plastic collar has multiple through holes for the absorbent cotton stick to pass through.

[0012] As a preferred embodiment of this utility model: the nano sponge ring is located at the gap where the flange and the connecting pipe meet, and the nano sponge ring wraps around the gap.

[0017] To provide a clearer explanation and illustration of the technical solution and implementation of this utility model, several preferred specific embodiments for implementing the technical solution of this utility model are described below. The following description is merely exemplary and not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these drawings, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically illustrate the concept and principle of the embodiments of this disclosure and do not necessarily show the specific dimensions and proportions of the various embodiments of this disclosure. The technical solution of this utility model will be clearly and completely described below in conjunction with embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model.

[0018] Example 1: A flange-type electromagnetic flowmeter capable of monitoring end-face leakage includes a flowmeter 1, which comprises a measuring conduit, measuring electrodes, an excitation coil, a magnetic circuit system, a housing, and a converter. Inlet and outlet ports 2 are connected to the left and right ports at the bottom of the flowmeter 1. Each inlet and outlet port 2 includes a flowmeter interface 2-1 fixedly connected to the port of the flowmeter 1, and a flange 2-2 fixed to the port of the flowmeter interface 2-1 away from the flowmeter 1. A connecting pipe 2-3 is connected to the outside of the flange 2-2. Multiple screws 2-4 pass through the connecting pipe 2-3 and the flange 2-2, and nuts 2-5 are screwed onto the outer threaded sections of each screw 2-4. The outer surface of the inlet / outlet port 2 is covered with an end-face leakage monitoring component 3. The end-face leakage monitoring component 3 includes two plastic collars 3-1. An annular groove is formed on the inner surface of the plastic collar 3-1, and a nano-sponge ring 3-5 is embedded in the annular groove. The outer surface of the nano-sponge ring 3-5 is fixedly connected to the inner surface of the annular groove inside the outer plastic collar 3-1. The remaining segments of the nano-sponge ring 3-5 are inserted into the annular groove inside the inner plastic collar 3-1 for coupling. The nano-sponge ring 3-5 is located at the gap where the flange 2-2 and the connecting pipe 2-3 meet, covering the gap. Multiple through holes 3-4 are formed on the outer ring of the plastic collar 3-1. Multiple absorbent cotton rods 3-2, fixed to the outer surface of the nano-sponge ring 3-5 and arranged in a circular array, pass through the through holes 3-4. A wood fiber block 3-3 is fixed to the outer end of each absorbent cotton rod 3-2. A groove is formed on the outer surface of each wood fiber block 3-3, and the inside of the groove is filled with moisture-sensitive ink. Multiple arc-shaped magnets are embedded and fixed on the end faces of the plastic collar 3-1 and the through hole 3-4 that are close to each other, for fixing the two plastic collars 3-1. When liquid leaks from the gap between the flange 2-2 and the connecting pipe 2-3, the nano sponge ring 3-5 absorbs the liquid, and the liquid is conducted to the wood fiber block 3-3 through the absorbent cotton swab 3-2. The moisture-sensitive ink changes color after sensing the liquid, indicating a leak at the end face.

[0019] Example 2: A flange-type electromagnetic flowmeter capable of monitoring end-face leakage. The flowmeter 1 also consists of a measuring conduit, measuring electrodes, an excitation coil, a magnetic circuit system, a housing, and a converter. The structure of the inlet and outlet ports 2 connected to the left and right ends at the bottom remains unchanged. The flowmeter interface 2-1 is fixed to the port of the flowmeter 1. The flange 2-2 is fixed to the side of the flowmeter interface 2-1 away from the flowmeter 1. The connecting pipe 2-3 is connected to the flange 2-2 via a screw 2-4 and a nut 2-5. In the end-face leakage monitoring component 3, the annular groove on the inner side of the plastic collar 3-1 is used to embed a nano-sponge ring 3-5. The nano-sponge ring 3-5 is fixed and coupled to the plastic collar 3-1 in the aforementioned manner and is located at the joint between the flange 2-2 and the connecting pipe 2-3. A through hole 3-4 is formed on the plastic collar 3-1. A liquid-absorbing cotton swab 3-2 passes through the through hole 3-4 and is fixed to the outer surface of the nano-sponge ring 3-5. A groove is formed on the wood fiber block 3-3 at the outer end of the liquid-absorbing cotton swab 3-2 and filled with moisture-sensitive ink. The difference lies in the fact that the plastic collar 3-1 and the through hole 3-4 have more and denser arc-shaped magnets embedded on their contact surfaces, which can more firmly fix the two plastic collars 3-1. During the use of the flow meter, if leakage occurs at the end face, the nano-sponge ring 3-5 absorbs the leaking liquid, which is then conducted through the absorbent cotton swab 3-2 to change the color of the moisture-sensitive ink, thereby realizing the monitoring of end face leakage.

[0020] Example 3: A flange-type electromagnetic flowmeter capable of monitoring end-face leakage. The flowmeter 1 still consists of a measuring conduit, measuring electrodes, an excitation coil, a magnetic circuit system, a housing, and a converter. The connection method of the inlet and outlet ports 2 remains unchanged. The flowmeter interface 2-1 connects to the flowmeter 1 port, and the flange 2-2 is connected to the other side of the flowmeter interface 2-1. The connecting pipe 2-3 is connected to the flange 2-2 via a screw 2-4 and a nut 2-5. In the end-face leakage monitoring component 3, a nano-sponge ring 3-5 is embedded in the annular groove on the inner side of the plastic collar 3-1. The fixing and coupling method of the nano-sponge ring 3-5 is the same as before, and it is located at the joint gap between the flange 2-2 and the connecting pipe 2-3. The plastic collar 3-1 has a through hole 3-4, and the absorbent cotton swab 3-2 passes through the through hole 3-4 and is fixed to the outer surface of the nano-sponge ring 3-5. The wood fiber block 3-3 at the outer end of the absorbent cotton swab 3-2 has a groove filled with moisture-sensitive ink. In this embodiment, the arc-shaped magnets embedded on the contact surfaces of the plastic collar 3-1 and the through hole 3-4 are semi-circular in shape, and the arc-shaped magnets have stronger magnetism, which can better attract and fix the two plastic collars 3-1. When leakage occurs at the end face, the nano-sponge ring 3-5 absorbs the liquid, and the moisture-sensitive ink changes color through the liquid-absorbing cotton swab 3-2, thereby achieving the purpose of monitoring the leakage at the end face.

[0021] Based on the above description, the workflow of this technical solution is explained as follows: Flowmeter 1 relies on the coordinated operation of its measuring conduit, measuring electrode, excitation coil, magnetic circuit system, housing, and converter to measure fluid flow rate; this is the basic function of flowmeter 1. When fluid passes through flowmeter 1, it enters and exits through the inlet / outlet ports 2 located at the bottom left and right. The flowmeter interface 2-1 in the inlet / outlet ports 2 is fixedly connected to the port of flowmeter 1. Flange 2-2 is fixed to the port of flowmeter interface 2-1 on the side away from flowmeter 1. Connecting pipe 2-3 is connected to flange 2-2 through multiple threaded rods 2-4 and nuts 2-5 screwed onto the outer threaded section of the threaded rods 2-4, thus connecting the pipeline to flowmeter 1 to transport fluid. During the operation of flowmeter 1, if end-face leakage occurs at the joint between flange 2-2 and connecting pipe 2-3, the end-face leakage monitoring component 3, which is wrapped around the outer surface of inlet / outlet ports 2, begins to function. The nano-sponge ring 3-5 in the end face leakage monitoring component 3 is located at the gap between the flange 2-2 and the connecting pipe 2-3 and wraps around the gap. The leaked liquid will be absorbed by the nano-sponge ring 3-5. Since multiple absorbent cotton rods 3-2 arranged in a ring array are fixed on the outer surface of the nano-sponge ring 3-5, and the absorbent cotton rods 3-2 pass through the through hole 3-4 opened on the outer ring of the plastic sleeve 3-1, the absorbed liquid will be conducted through the absorbent cotton rods 3-2. A wood fiber block 3-3 is fixed to the outer end of the absorbent cotton rod 3-2. The groove opened on the outer surface of the wood fiber block 3-3 is filled with moisture-sensitive ink. When the liquid is conducted to the wood fiber block 3-3, the moisture-sensitive ink will change color after sensing the liquid. By observing whether the moisture-sensitive ink changes color, it can be known whether there is an end face leakage. Meanwhile, multiple arc-shaped magnets are embedded and fixed on the end faces of the plastic collar 3-1 and the through hole 3-4 that are close to each other, which can make the two plastic collars 3-1 attract and fix each other, ensuring that the end face leakage monitoring component 3 can be stably wrapped around the outer ring of the inlet and outlet liquid port 2 for monitoring.

[0022] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
