Description

Technical Field

[0001] The utility model relates to the technical field of current devices, and more specifically, to a grounding ring of an electromagnetic flowmeter. Background Art

[0002] Electromagnetic flowmeter is a flowmeter that measures flow based on Faraday's law of electromagnetic induction. The electromagnetic flowmeter grounding ring is a component that must be used under certain conditions, especially when the pipeline is non-metallic or has a PTFE lining. Its main function is to ensure accurate measurement and prevent current corrosion of the electrode.

[0003] A common installation method is to open a flange on the electromagnetic flowmeter and design a circular groove on the electromagnetic flowmeter grounding ring so that the grounding ring can be smoothly inserted into the flowmeter sensor tube. Then, use the fixing screw to firmly install the grounding ring on the fixing hole on the side of the electromagnetic flowmeter flange. However, although this installation method is effective, it does have some potential problems. First, because the installation steps are relatively cumbersome and involve multiple links and details, if the installer's technical level is not high or the operation is improper, it is easy to make mistakes in a certain link, so that the grounding ring is not tightly connected, which may cause the potential difference to be unable to be effectively eliminated, thereby affecting the accuracy of the measurement; secondly, the unstable connection may also have an adverse effect on the performance of the electromagnetic flowmeter. Since the electromagnetic flowmeter needs to withstand the pressure and impact of the fluid during operation, if the grounding ring is not firmly connected, it may loosen or fall off after long-term use, thereby affecting the stability and reliability of the entire flowmeter. Therefore, this paper is dedicated to a new electromagnetic flowmeter grounding ring. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 5 As shown, the utility model provides an electromagnetic flowmeter grounding ring, comprising an electromagnetic flowmeter 1 and a grounding ring 2, a fixing plate 3 is fixedly installed on the side of the electromagnetic flowmeter 1, a sleeve 4 is arranged inside the fixing plate 3 and extends out of the two ends of the outside of the fixing plate 3, a threaded rod 5 is movably installed inside the sleeve 4, and a handle 6 is fixedly installed at one end of the threaded rod 5;

[0025] A connecting plate 7 is fixedly mounted on the other end of the threaded rod 1 5. A sleeve 2 8 is arranged inside the connecting plate 7 and extends out of the two ends of the outside of the fixed plate 3. A threaded rod 2 9 is movably mounted inside the sleeve 2 8. A handle 2 10 is fixedly mounted on one end of the threaded rod 2 9, and a pressure plate 11 is fixedly mounted on the other end of the threaded rod 2 9.

[0026] Before use, the grounding ring 2 is placed as a whole inside the electromagnetic flowmeter 1. After that, the staff turns the handle 1 6 to make the threaded rod 1 5 rotate inside the sleeve 1 4, so as to adjust the distance between the connecting plate 7 and the grounding ring 2. When the connecting plate 7 is located in front of the grounding ring 2, the staff turns the pressing plate 11 to make the threaded rod 2 9 rotate inside the sleeve 2 8, so that the handle 2 10 gradually approaches the surface of the grounding ring 2 and finally clings to the surface of the grounding ring 2, so as to fix the grounding ring 2.

[0027] After turning the handle 6 to move the threaded rod 5 forward so that the connecting plate 7 is located in front of the grounding ring 2, turn the pressure plate 11 to make the handle 2 10 at one end of the threaded rod 2 9 close to the surface of the grounding ring 2. Compared with the traditional device, this device presses one end of the grounding ring 2 through the handle 2 10 to make the electromagnetic flowmeter 1 and the grounding ring 2 fit more closely, so that the lining of the electromagnetic flowmeter 1 that is severely worn can be protected when the device is used, avoiding severe wear of the fluid and increasing the service life of the electromagnetic flowmeter.

[0028] Among them, a clamping block 16 is fixedly installed on the side of the grounding ring 2, a circular ring plate 13 is fixedly installed on the bottom of the grounding ring 2, and a rectangular groove 14 is opened on the front of the electromagnetic flowmeter 1;

[0029] A circular groove 15, which is provided inside the rectangular groove 14;

[0030] An annular groove 12, the annular groove 12 is provided on the front side of the electromagnetic flowmeter 1;

[0031] After the electromagnetic flowmeter 1 and the grounding ring 2 are fitted together, the clamping block 16 enters the rectangular groove 14 and approaches the bottom thereof, and then the staff rotates the grounding ring 2 as a whole clockwise, so that the clamping block 16 as a whole rotates inside the circular groove 15, so that the grounding ring 2 as a whole is clamped inside the electromagnetic flowmeter 1;

[0032] After the clamping block 16 enters the rectangular groove 14, the grounding ring 2 is rotated as a whole to make the grounding ring 2 enter the circular groove 15. Compared with the traditional device, this device can usually provide a stable connection through the clamping method of the clamping block 16 and the circular groove 15, ensuring that the electromagnetic flowmeter 1 and the grounding ring 2 are not easy to loosen or separate, and can effectively resist external forces to prevent loosening or falling off due to vibration, impact and other factors, thereby ensuring the reliability of the connection.

[0033] There are two blocks 16 and two rectangular slots 14, and the two blocks 16 and the two rectangular slots 14 are divided into two groups.

[0034] There are two blocks 16 and two rectangular grooves 14 , which are divided into two groups. The two blocks 16 enter the interior of the rectangular groove 14 at the same time and the grounding ring 2 is rotated to make the blocks 16 enter the interior of the circular groove 15 , thereby improving the connectivity between the electromagnetic flowmeter 1 and the grounding ring 2 .

[0035] Among them, the connection between the electromagnetic flowmeter 1 and the fixing plate 3 is provided with reinforcing ribs 17, and the number of the reinforcing ribs 17 is two groups, and the number of each group of reinforcing ribs 17 is three;

[0036] Reinforcing ribs 17 are provided at the connection between the electromagnetic flowmeter 1 and the fixing plate 3, and there are two groups of reinforcing ribs 17, and each group of reinforcing ribs 17 has three reinforcing ribs. When two groups of reinforcing ribs 17 are used, the fixing plate 3 and the electromagnetic flowmeter 1 are more firmly connected, thereby preventing the fixing plate 3 from detaching from the surface of the electromagnetic flowmeter 1.

[0037] The bottoms of the two handles 10 are both provided with a rubber layer, and the two handles 10 are equal in shape and size;

[0038] The bottoms of the two handles 10 are both provided with a rubber layer, and the two handles 10 are equal in shape and size. The use of the rubber layer prevents the surface of the grounding ring 2 from being damaged when the handles 10 are pressed down, thereby preventing problems from occurring during use.

[0039] The inner diameter of the annular groove 12 is equal to the outer diameter of the annular plate 13, and the entire electromagnetic flowmeter 1 and the entire grounding ring 2 are both made of stainless steel;

[0040] The inner diameter of the annular groove 12 is equal to the outer diameter of the annular plate 13. When the annular plate 13 enters the annular groove 12, it will fit more closely. The entire electromagnetic flowmeter 1 and the entire grounding ring 2 are made of stainless steel. Stainless steel has good corrosion resistance and can resist the erosion of many chemical substances. Stainless steel is heat-resistant, high-temperature-resistant and low-temperature-resistant, and thus has excellent physical properties.

[0041] The working principle and use process of this utility model:

[0042] Before use, the grounding ring 2 is placed as a whole inside the electromagnetic flowmeter 1. After that, the staff turns the handle 6 to make the threaded rod 5 rotate inside the sleeve 4, so as to adjust the distance between the connecting plate 7 and the grounding ring 2. When the connecting plate 7 is located in front of the grounding ring 2, the staff turns the pressure plate 11 to make the threaded rod 29 rotate inside the sleeve 28, so that the handle 2 10 gradually approaches the surface of the grounding ring 2 and finally clings to the surface of the grounding ring 2 to fix the grounding ring 2.

[0043] When the electromagnetic flowmeter 1 and the grounding ring 2 are fitted together, the clamping block 16 enters the interior of the rectangular groove 14 and approaches its bottom. Then, the staff rotates the grounding ring 2 as a whole clockwise, so that the clamping block 16 as a whole rotates inside the circular groove 15, thereby making the grounding ring 2 as a whole clamped inside the electromagnetic flowmeter 1.
