Description

Technical Field

[0001] This utility model belongs to the field of central control device technology, specifically a central control device for a flow meter. Background Technology

[0002] In industrial sectors such as petrochemicals, municipal water supply, and energy metallurgy, the flow measurement and precise control of fluids (liquids, gases, and steam) are core aspects of ensuring production efficiency, reducing energy consumption, and ensuring process compliance. The central control device for flow meters serves as a key hub connecting the flow meter and the production control system, undertaking the core functions of "data acquisition, logic operation, execution control, and information feedback." By receiving the flow signal (such as pulses or analog signals) from the flow meter, it adjusts valves, baffles, and other actuators in real time to stabilize the flow within a preset range. At the same time, it uploads the operating data to the host computer to support production scheduling and fault diagnosis.

[0003] In industrial fluid metering systems, the mechanical connection between the flow meter and the central control device is the core prerequisite for ensuring stable transmission of flow signals and precise operation of the regulating mechanism. Most of these mechanical connections use flange connections. Flange connections require alignment and calibration to ensure that the flange and flange hole are aligned before the connection port can be connected to the flow meter. The existing alignment method is usually manual docking, which is easily affected by factors such as arm pain and shaking, making the installation work cumbersome and reducing the installation efficiency of the flow meter. Summary of the Invention

[0004] The purpose of this invention is to provide a central control device for flow meters to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions: A central control device for a flow meter includes a central control device body, a connection port fixedly connected to the bottom of the central control device body, a flow meter being fitted to the bottom of the connection port, a flange being provided between the flow meter and the connection port, and limit components being provided on both the connection port and the outer wall of the flow meter. The limiting component includes two sets of movable chambers symmetrically fixedly connected to the outer wall of the connection port. A positioning post is fixedly connected to the bottom of the movable chamber. Positioning holes are opened on the flow meter and the surface of the connection port corresponding to the bottom of the positioning post. The positioning holes are slidably connected to the positioning post. A spring is fixedly connected to the inner wall of the movable chamber. A sliding disc is slidably connected inside the movable chamber. The sliding disc is in contact with one end of the spring. A guide groove is opened on the outer wall of the movable chamber. A brake rod is fixedly connected to the outer wall of the sliding disc in the guide groove.

[0006] Preferably, two sets of limiting grooves are provided on the side wall of the guide groove, and a plug rod is rotatably connected to the side of the sliding disc away from the spring. The plug rod is slidably connected to the movable chamber, and a socket is fixedly connected to the outer wall of the flow meter corresponding to the other end of the plug rod. The plug rod is slidably connected to the socket.

[0007] Preferably, the spring is fixedly connected to the middle position of the inner wall of the movable compartment, and the other end of the spring is attached to the middle of the inner wall of the sliding disk.

[0008] Preferably, the positioning post is cylindrical in shape, and the positioning hole is a through hole adapted to the positioning post.

[0009] Preferably, the connection between the flow meter and the connection port is equipped with a sealing ring, and the two sets of sealing rings fit together.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a flow meter to align the positioning hole onto a positioning post, ensuring alignment between the flow meter and the flange and flange hole in the connection port, as well as the socket and insertion rod. Then, rotating the brake lever causes the sliding disc to rotate within the movable chamber, sliding from the limiting groove into the guide groove. The spring's restoring force then pushes the sliding disc back to its original position within the movable chamber, simultaneously driving the insertion rod into the socket. Rotating the brake lever and the limiting groove again causes the brake lever to enter another set of limiting grooves, thus achieving the positioning of the flow meter and the flange hole and flange in the connection port, facilitating flow meter installation and improving installation efficiency.

Detailed Implementation

[0015] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1-5 As shown, a central control device for a flow meter includes a central control device body 1. A connection port 3 is fixedly connected to the bottom of the central control device body 1. A flow meter 4 is attached to the bottom of the connection port 3. A flange 5 is provided between the flow meter 4 and the connection port 3. Limiting components 6 are provided on the outer walls of both the connection port 3 and the flow meter 4. The limiting components 6 include two sets of movable chambers 61 symmetrically fixedly connected to the outer wall of the connection port 3. A positioning post 62 is fixedly connected to the bottom of each movable chamber 61. Positioning holes 63 are provided on the surfaces of the flow meter 4 and the connection port 3 corresponding to the bottom of the positioning post 62. The positioning holes 63 are slidably connected to the positioning post 62. A spring 64 is fixedly connected to the inner wall of the movable chamber 61. A sliding disc 65 is slidably connected inside the movable chamber 61. The sliding disc 65 is in contact with one end of the spring 64. A guide groove 66 is provided on the outer wall of the movable chamber 61. A brake rod 67 is fixedly connected to the outer wall of the sliding disc 65 in the guide groove 66. Two sets of limiting grooves 68 are provided on the side wall of the guide groove 66. A plug rod 69 is rotatably connected to the side of the sliding disc 65 away from the spring 64. The plug rod 69 is slidably connected to the movable chamber 61. A socket 610 is fixedly connected to the outer wall of the flow meter 4 corresponding to the other end of the plug rod 69. The plug rod 69 is slidably connected to the socket 610.

[0017] In practice, the flow meter 4 drives the positioning hole 63 to fit onto the positioning post 62, aligning the flow meter 4 with the flange 5 and flange hole in the connection port 3, and simultaneously aligning the socket 610 with the insertion rod 69. Then, the brake lever 67 is rotated, causing the brake lever 67 to drive the sliding disc 65 to rotate in the movable chamber 61, and causing the brake lever 67 to slide from the limiting groove 68 and rotate into the guide groove 66. At this time, the restoring force of the spring 64 will push the sliding disc 65 to reset and slide in the movable chamber 61. Then, the sliding disc 65 synchronously drives the insertion rod 69 to be inserted into the socket 610. Next, the brake lever 67 and the limiting groove 68 are rotated, causing the brake lever 67 to rotate into another set of limiting grooves 68, thereby achieving the positioning of the flow meter 4 with the flange hole and flange 5 in the connection port 3, so as to install the flow meter 4 and improve the installation efficiency of the flow meter 4.

[0018] As a technical optimization of this utility model, the spring 64 is fixedly connected to the middle position of the inner wall of the movable chamber 61, and the other end of the spring 64 is attached to the middle of the inner wall of the sliding disk 65.

[0019] In practice, this design ensures that the spring 64 is less likely to shift within the movable chamber 61, thereby guaranteeing that the spring force of the spring 64 is evenly distributed to the sliding disk 65, allowing the sliding disk 65 to slide back and forth stably within the movable chamber 61.

[0020] As a technical optimization of this utility model, the positioning post 62 is designed in a cylindrical shape, and the positioning hole 63 is opened as a through hole adapted to the positioning post 62.

[0021] In practice, this increases the contact area between the positioning post 62 and the positioning hole 63, and reduces the occurrence of the positioning post 62 becoming loose in the positioning hole 63, thereby improving the positioning accuracy of the flow meter 4 and the flange hole of the flange 5.

[0022] As a technical optimization of this utility model, the flow meter 4 and the connection port 3 are respectively equipped with sealing rings, and the two sets of sealing rings fit together.

[0023] In practice, the flow meter 4 can be connected to the connection port 3 through the flange 5, and the two sets of sealing rings in the flow meter 4 and the connection port 3 can be tightly fitted together as the flow meter 4 and the connection port 3 move, thereby improving the sealing performance at the connection between the flow meter 4 and the connection port 3 and preventing fluid leakage in the flow meter 4 or the connection port 3.

[0024] As a technical optimization of this utility model, a microcontroller 2 is fixedly connected to the front end of the central control device body 1, and a flow sensor 7 and a temperature and pressure sensor 8 are symmetrically fixedly connected to the inner wall of the connection port 3, and the flow sensor 7 and the temperature and pressure sensor 8 are electrically connected to the microcontroller 2 respectively.

[0025] In practice, the flow rate, temperature and pressure in the connection port 3 or flow meter 4 are detected by the flow sensor 7 and the temperature and pressure sensor 8. When the detected value exceeds the threshold, the flow sensor 7 and the temperature and pressure sensor 8 will send the data to the microcontroller 2, and then the microcontroller 2 will output it to the sound and light alarm module. At this time, the alarm module will sound an alarm, thereby enabling the central control device body 1 to have an abnormal alarm function.

[0026] As a technical optimization of this utility model, the central control device body 1 is provided with sound and light alarm modules on both sides, and the microcontroller 2 is electrically connected to the sound and light alarm modules.

[0027] In practice, when the microcontroller 2 compares the real-time data collected from the flow sensor 7 and the temperature and pressure sensor 8 with the preset safety threshold, the microcontroller 2 transmits the alarm information to the sound and light alarm module, causing the sound and light alarm module to sound an alarm, thereby enabling the user to react quickly.

[0028] In use, the flow meter 4 first moves the positioning hole 63 onto the positioning post 62, aligning the flow meter 4 with the flange 5 and flange hole in the connection port 3, and simultaneously aligning the socket 610 with the insertion rod 69. Then, the brake lever 67 is rotated, causing the brake lever 67 to rotate the sliding disc 65 within the movable chamber 61, and the brake lever 67 slides from the limiting groove 68 and rotates into the guide groove 66. At this time, the restoring force of the spring 64 pushes the sliding disc 65 to reset and slide within the movable chamber 61. Then, the sliding disc 65 synchronously drives the insertion rod 69 to insert into the socket 610. Next, the brake lever 67 and the limiting groove 68 are rotated, causing the brake lever 67 to rotate into another set of limiting grooves 68, thereby achieving the positioning of the flow meter 4 with the flange hole and flange 5 in the connection port 3.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
