Description

Technical Field

[0001] This utility model relates to the field of liquid level gauge technology, and in particular to a liquid level gauge for factory use that can be quickly disassembled and assembled. Background Technology

[0002] In chemical plant production processes, level gauges are crucial instruments for monitoring the liquid level in equipment such as storage tanks and reaction vessels. Traditional level gauges suffer from problems such as cumbersome disassembly and assembly, poor sealing, and difficult maintenance.

[0003] Magnetic float level gauges are mainly based on the principles of communicating vessels and magnetic coupling to achieve real-time measurement and display of liquid levels. When the liquid level in the measured container rises or falls, the float in the main pipe of the level gauge also rises or falls accordingly. The permanent magnet inside the float transmits the signal to the on-site indicator through magnetic coupling. Existing magnetic level gauges, when installed on the outer wall of the container, have their flange end on the gauge itself connected to the flange end of the pipe on the container. Traditionally, the flange ends are fixed sequentially by multiple sets of bolts, making disassembly and assembly cumbersome and inconvenient. A search of patent numbers reveals the following: 1. CN102706378A, a corrosion-resistant level gauge for chemical applications, has the disadvantage of using an integral welded structure, which, while offering good corrosion resistance, does not allow for quick replacement of sensor components and requires shutdown and liquid drainage for maintenance; 2. CN208366154U, a quick-installation level gauge, has the disadvantage of relying on spring clips for fixation, which can easily loosen in chemical vibration environments, posing a safety hazard; 3. CN105823553A, an intelligent level detection device, has the disadvantage of high integration of electronic components and mechanical structure, requiring replacement of the entire device for partial damage, resulting in high maintenance costs.

[0004] In summary, the existing technologies generally suffer from the following drawbacks: low disassembly and assembly efficiency; poor sealing reliability: traditional gaskets are prone to failure in corrosive media; weak structural adaptability: it is difficult to meet both rapid disassembly and vibration protection requirements; and high maintenance costs: specialized tools are required for replacement.

[0005] Therefore, we propose a liquid level gauge for chemical enterprises that can be quickly disassembled and assembled. Summary of the Invention

[0006] The purpose of this utility model is to provide a quick-assembly and disassembly-friendly liquid level gauge for factory use, which is easy to disassemble and carry. To achieve the above objective, this utility model adopts the following technical solution, which includes a magnetic level gauge, a liquid guide tube, and a delivery outer tube on an external container. A fixed flange is fitted on the outside of the liquid guide tube, and a docking flange is fitted on the outside of the delivery outer tube. Notches are provided at the upper and lower positions of the outer periphery of the fixed flange, and a locking shaft is rotatably connected inside the notches. Mounting grooves are provided at the upper and lower positions of the outer periphery of the docking flange. An external thread is provided on the outer periphery of the locking shaft, and a locking sleeve is threaded to the outside of the locking shaft through the external thread. A dial is installed on the outer periphery of the locking sleeve.

[0007] Preferably, when the fixed flange is installed with the docking flange, after the locking shaft inside the notch is engaged with the mounting groove, the locking sleeve is rotated by the pivot to dock with the docking flange, and the fixed flange and the docking flange are locked in a fixed state.

[0008] Preferably, one end of the mating flange is provided with a slot, and one end of the fixed flange is equipped with a limit plug. The fixed flange and the mating flange are mutually inserted and limited by the slot and the limit plug.

[0009] Preferably, a sealing gasket is provided on the inner side of the liquid guide tube. The sealing gasket itself has deformation characteristics. When the outer delivery tube is inserted into the liquid guide tube, the outer periphery of the outer delivery tube and the sealing gasket are in a mutually fitted and sealed state.

[0010] Preferably, the magnetic potential gauge has an assembly screw groove that penetrates the magnetic potential gauge on its periphery. The cross-section of the assembly screw groove is T-shaped. One end of the liquid guide tube has a connecting thread on its periphery. The periphery of the liquid guide tube is connected to the internal thread of the assembly screw groove through the connecting thread.

[0011] This utility model has the following beneficial effects:

[0012] 1. When installing this device with an external container, the liquid guide tube can be inserted into the external delivery pipe, allowing the fixed flange on the outside of the liquid guide tube and the docking flange on the outside of the delivery pipe to align. Then, the locking shaft inside the notch is rotated and inserted into the mounting groove for alignment. The locking sleeve outside the locking shaft is then rotated by the pivot, and the fixed flange and the docking flange are fixed and limited by the locking sleeve. The fixed flange and the docking flange can be mutually inserted and limited through slots and limit plugs to ensure the stability of the installation and connection between the fixed flange and the docking flange. After the delivery pipe is inserted into the liquid guide tube, it can be sealed with a sealing gasket to ensure a sealing effect. Disassembly is carried out in the same way, thereby achieving the effect of convenient and quick assembly and disassembly of the magnetic level gauge.

[0013] 2. The liquid guide tube and the magnetic level gauge are connected in an assembly manner. When using the magnetic level gauge, the liquid guide tube can be threaded into the assembly screw groove on the periphery of the magnetic level gauge. Disassembly is the same. In this way, the magnetic level gauge and the liquid guide tube can be disassembled and used separately, thus achieving the effect of convenient use, disassembly and transportation.

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 scope of protection of the present utility model.

[0022] Example 1: This utility model includes a magnetic level gauge 1, a liquid guide tube 2, and a delivery outer tube 4 on an external container. A fixed flange 3 is fitted around the liquid guide tube 2, and a docking flange 5 is fitted around the delivery outer tube 4. A sealing gasket 6 is provided on the inner side of the liquid guide tube 2. Notches 7 are provided at the upper and lower outer periphery of the fixed flange 3, and a locking shaft 8 is rotatably connected inside the notches 7. Mounting grooves 9 are provided at the upper and lower outer periphery of the docking flange 5. An external thread 10 is provided on the outer periphery of the locking shaft 8. A locking sleeve 11 is connected to the outer periphery of the locking shaft 8 through the external thread 10. A pivot shaft 12 is installed around the outer periphery of the locking sleeve 11. An assembly screw groove 13 penetrating the magnetic level gauge 1 is provided on the outer periphery of the magnetic level gauge 1. The cross-section of the assembly screw groove 13 is a T-shaped structure. A connecting thread 14 is provided on the outer periphery of one end of the liquid guide tube 2. A slot 15 is provided at one end of the docking flange 5. A limit plug 16 is installed at one end of the fixed flange 3. The fixed flange 3 and the docking flange 5 are mutually inserted and limited by the slot 15 and the limit plug 16.

[0023] Furthermore, when the fixed flange 3 is installed in conjunction with the mating flange 5, after the locking shaft 8 inside the control notch 7 is engaged with the mounting groove 9, the locking sleeve 11 is rotated by the pivot shaft 12 to mate with the mating flange 5, and the fixed flange 3 and the mating flange 5 are in a locked state.

[0024] Furthermore, the sealing gasket 6 itself has deformation characteristics, and when the outer delivery tube 4 is inserted into the liquid guide tube 2, the outer periphery of the outer delivery tube 4 and the sealing gasket 6 are in a mutually fitted and sealed state.

[0025] Furthermore, the outer periphery of the liquid guide tube 2 is connected to the internal thread of the assembly screw groove 13 via the connecting thread 14.

[0026] The working principle of this utility model:

[0027] When the magnetic level gauge 1 is installed with an external container, the liquid guide tube 2 can be inserted into the external delivery tube 4, allowing the fixed flange 3 on the outside of the liquid guide tube 2 and the docking flange 5 on the outside of the delivery tube 4 to align. Then, the locking shaft 8 inside the notch 7 is rotated and inserted into the mounting groove 9 for alignment. Finally, the locking screw sleeve 11 on the outside of the locking shaft 8 is rotated via the pivot 12, thereby securing the fixed flange 3 and the docking flange 5. The fixed flange 3 and the docking flange 5 can be interlocked via the slot 15 and the limiting insert 16. The limit switch ensures the stability of the installation and connection between the fixed flange 3 and the docking flange 5. After the outer conveying pipe 4 is inserted into the liquid guide pipe 2, it can be sealed and fitted by the sealing gasket 6 to ensure the sealing effect. The same applies to disassembly, which facilitates the quick assembly and disassembly of the magnetic level gauge 1. The liquid guide pipe 2 and the magnetic level gauge 1 are connected in an assembly manner. When using the magnetic level gauge 1, the liquid guide pipe 2 can be threaded into the assembly screw groove 13 on the periphery of the magnetic level gauge 1. The same applies to disassembly, so the magnetic level gauge 1 and the liquid guide pipe 2 can be disassembled and assembled separately for subsequent use.
