Electrode assembly for electromagnetic flowmeter and electromagnetic flowmeter

Abstract

This utility model relates to an electrode assembly of an electromagnetic flowmeter and the electromagnetic flowmeter itself, comprising: a base having a through-zone for fluid passage; a sealing plate, which is movably and sealed to the base, with its two sides facing the through-zone and the outer side of the base, respectively; and a spring assembly connected between the base and the sealing plate. Compared to the prior art, in this utility model, during assembly, when the fluid flows within the pipe cavity, the fluid's own pressure can exert an outward squeezing effect on the sealing plate, thereby pressing the sealing plate against the pressure plate and increasing the sealing effect between the sealing plate and the pressure plate, thus improving the overall sealing effect of the electrode rod mounted on the base.

Description

Technical Field

[0001] This utility model belongs to the technical field of flow detection equipment, specifically an electrode assembly and an electromagnetic flow meter. Background Technology

[0002] Electromagnetic flow meters are commonly used flow measurement instruments, widely applied in industrial production, water treatment, petrochemicals, and other fields. They measure fluid flow by utilizing the induced electromotive force generated when a conductive liquid passes through a magnetic field, based on Faraday's law of electromagnetic induction. This measurement process mainly involves the cooperation of two parts: the main body, equipped with a permanent magnet or excitation element to provide the magnetic field; and the electrode assembly, which is mounted on the main body and extends into the pipe cavity to contact the fluid. To allow for regular cleaning and maintenance of the electrode assembly, it must be detachably mounted on the main body, preventing it from being integrally encapsulated with the main body.

[0003] The problem that is currently faced is that, due to structural design reasons, when the electrode assembly is inserted into the main body, it is easy to cause poor sealing due to insufficient contact, which makes it easy to cause fluid leakage. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] In view of the following technical problems in the existing technology: when assembling the electrode assembly and the main body, inadequate contact between the two can easily lead to poor sealing and fluid leakage. To solve this technical problem, this utility model provides the following technical solution:

[0006] An electromagnetic flowmeter, comprising:

[0007] The base has a through zone for fluid to pass through;

[0008] A sealing plate is movably connected to the base in a sealed manner, with its two sides facing the through area and the outside of the base, respectively.

[0009] A spring assembly is connected between the base and the sealing plate.

[0010] As a preferred technical solution for an electromagnetic flowmeter, the edge of the sealing plate is connected to the base via a first sealing gasket.

[0011] As a preferred technical solution for an electromagnetic flowmeter, a raised edge is constructed at the edge of the first sealing gasket, and the raised edge is embedded in the base and the sealing plate.

[0012] As a preferred technical solution for an electromagnetic flowmeter, the sealing plate is slidably connected to the base.

[0013] As a preferred technical solution for an electromagnetic flowmeter, a slider is constructed on the sealing plate, and a guide groove is constructed on the base, which slides in cooperation with the slider.

[0014] As a preferred technical solution for an electromagnetic flowmeter, one end of the spring assembly is connected to the slider.

[0015] As a preferred technical solution for an electromagnetic flowmeter, the spring assembly is located within the guide groove.

[0016] An electrode assembly for an electromagnetic flowmeter includes:

[0017] The electrode rod moves through the sealing plate;

[0018] The pressure plate is integrally formed with the electrode rod and is located around the electrode rod;

[0019] The second sealing gasket is fitted onto one side of the pressure plate and is used to contact the sealing plate.

[0020] The electrode rod and the base are fixedly connected by a fixing component.

[0021] As a preferred technical solution for the electrode assembly of an electromagnetic flowmeter, the fixing member is connected to the electrode rod and threadedly engaged with the base.

[0022] In a preferred embodiment of the electrode assembly of an electromagnetic flowmeter, the fixing member is rotatably engaged with the tail of the electrode rod.

[0023] The beneficial effects of the electrode assembly and electromagnetic flowmeter provided by this utility model are as follows: Compared with the prior art, when the flowmeter is assembled, the fluid in the pipe cavity is flowing, and the pressure of the fluid itself can exert an outward squeezing effect on the sealing plate, thereby pressing the sealing plate onto the pressure plate to increase the sealing effect between the sealing plate and the pressure plate, thereby increasing the sealing effect of the entire electrode rod installed on the base.

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0034] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0035] Reference Figure 2-5 One embodiment of this utility model provides an electromagnetic flowmeter, which includes:

[0036] Base 1, which is a shell-like structure, needs to have a through area 101 for fluid to pass through. For example, base 1 can be in the shape of a pipe joint. When it is installed on the pipeline, its two ends of the pipe structure can be connected to the pipeline.

[0037] The sealing plate 3 is intercepted and disposed on the wall shell of the base 1 and is connected to the base 1 in a sealed manner. The two sides of the sealing plate 3 face the through area 101 and the outside of the base 1, respectively.

[0038] Spring assembly 4 is connected between the base 1 and the sealing plate 3, so that the sealing plate 3 is in a fixed position on the base 1 when it is in normal state;

[0039] Based on the above, the electrode assembly corresponding to the flowmeter described in this utility model needs to be equipped with a contact surface. When the electrode assembly is fixedly installed on the base 1, its end passes through the sealing plate 3. The contact surface on the electrode assembly will push the sealing plate 3, causing it to contact the sealing plate 3. Under the action of the spring assembly 4, the sealing plate 3 has a tendency to return to the fixed position, causing it to abut against the contact surface, thereby increasing the contact effect between it and the electrode assembly. During the flow measurement process, the pressure formed by the fluid passing through the pipeline will be applied to the sealing plate 3, thereby further increasing the contact force of the sealing plate 3 on the contact surface, so as to increase the tightness of the fit between the two, thereby increasing the sealing effect. That is, the greater the fluid pressure, the more fully the fit, and the better the sealing effect.

[0040] Furthermore, refer to Figure 3 and Figure 5 Regarding the sealing connection between the sealing plate 3 and the base 1, the edge of the sealing plate 3 is connected to the base 1 by a first sealing gasket 5. The flexibility of the first sealing gasket 5 allows the sealing plate 3 and the base 1 to form a relatively movable relationship, while maintaining a sufficient sealing effect between them. In order to increase the firmness of the connection between the first sealing gasket 5, the base 1, and the sealing plate 3, a protruding edge 501 can be constructed at the edge of the first sealing gasket 5. The protruding edge 501 can be directly embedded in the base 1 and the sealing plate 3.

[0041] Furthermore, the sealing plate 3 and the base 1 can be slidably connected, which allows for linear guidance of the movement of the sealing plate 3 on the base 1, thus enabling it to more fully conform to the electrode assembly when it moves; regarding the configuration of the sliding relationship, preferably, refer to Figure 2-5 For example, a slider 301 can be constructed on the sealing plate 3, and a guide groove 102 can be constructed on the base 1, so that a sliding fit is formed between the guide groove 102 and the slider 301, thereby maintaining the stable movement of the sealing plate 3.

[0042] Furthermore, referring to Figures 2-5, when the spring assembly 4 is connected to the sealing plate 3, one end of it can be directly connected to the slider 301. The number of spring assemblies 4 is consistent with the number of combinations formed between the slider 301 and the guide groove 102. When the spring assembly 4 is connected to the slider 301, its force on the sealing plate 3 and its position for guiding the direction of the sealing plate 3 are at the same point, thereby better maintaining the stability of the sealing plate 3 during its movement.

[0043] Furthermore, refer to Figure 3 The spring assembly 4 can be directly arranged in the guide groove 102, which can protect the spring assembly 4 and prevent the spring assembly 4 from deviating.

[0044] Furthermore, this embodiment also provides an electrode assembly for an electromagnetic flowmeter, which includes the following parts:

[0045] Electrode rod 2, which moves through the sealing plate 3;

[0046] The pressure plate 6 is integrally formed with the electrode rod 2 and is located around the electrode rod 2. The pressure plate 6 serves as a contact surface and is used to cooperate with the sealing plate 3.

[0047] The second sealing gasket 7 is fitted onto one side of the pressure plate 6 and is used to contact the sealing plate 3. Through the action of the second sealing gasket 7, the sealing effect between the pressure plate 6 and the sealing plate 3 will be better.

[0048] Regarding the function of the fastener 8, specifically, the process of maintaining a fixed connection and making the electrode rod 2 and the base 1 detachable is achieved through the fastener 8.

[0049] When the electrode assembly is installed on the flow meter, it is fixed to the base 1 by the fastener 8. The end of the electrode rod 2 passes through the middle of the sealing plate 3 and extends into the through area 101, thereby contacting the fluid. The sealing plate 3 is tightly attached to the second sealing gasket 7 under the action of fluid pressure, thereby fully maintaining the sealing effect between the electrode assembly and the sealing plate 7.

[0050] Furthermore, refer to Figure 1-5The fixing member 8 is connected to the electrode rod 2 and has a threaded connection with the base 1, so it can be fixed to the base 1 by rotation, so that the electrode rod 2 can be installed on the base 1, making the disassembly and assembly process simple and convenient. In order to prevent the electrode rod 2 from rotating synchronously during the rotation of the fixing member 8, the fixing member 8 and the electrode rod 2 can be set to a rotational fit relationship. So when the pressure plate 6 on the electrode rod 2 has already contacted the sealing plate 3, the electrode rod 2 will not be synchronously driven during the process of tightening the fixing member 8.

[0051] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
