Description

Technical Field

[0001] This utility model relates to the field of flow meters, and more specifically, to a flow meter with valve control. Background Technology

[0002] In fields such as industrial production, energy management, and environmental monitoring, flow measurement is a crucial link in achieving process control, resource allocation, and safe operation. With the continuous improvement of industrial automation, higher demands are being placed on the functionality, reliability, and convenience of flow meters.

[0003] Traditional valve-controlled flow meters often require complex operations with the aid of tools during installation and are susceptible to loosening due to vibration and fluid impact, leading to increased measurement errors and frequent equipment failures.

[0004] Therefore, it is necessary to redesign a flow meter with valve control to address the above-mentioned problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a flow meter with valve control.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A valve-controlled flow meter includes a pipe and a flow meter. A fixing hole is provided on the outer wall of the pipe. Two fixing blocks are symmetrically installed on the outer wall of the pipe. Each fixing block has an installation groove on one side, and a limiting device is provided in each installation groove. Moving grooves are provided on both sides of each fixing block. A display screen is fixedly installed at one end of the flow meter. A fixing pipe is fixedly connected to the outer wall of the flow meter. A protective sleeve is fixedly installed on the outer wall of the fixing pipe.

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1-5 A valve-controlled flow meter includes a pipe 1 and a flow meter 2. A fixing hole 11 is provided on the outer wall of the pipe 1. Two fixing blocks 4 are symmetrically installed on the outer wall of the pipe 1. Each fixing block 4 has an installation groove 15 on one side, and a limiting device is provided in each installation groove 15. Moving grooves 12 are provided on both sides of each fixing block 4. A display screen 3 is fixedly installed at one end of the flow meter 2. A fixing pipe 5 is fixedly connected to the outer wall of the flow meter 2. A protective sleeve 6 is fixedly installed on the outer wall of the fixing pipe 5. Multiple circumferential openings are provided on the outer wall of the protective sleeve 6. The limiting hole 8 is connected to the output end of the limiting device and the corresponding limiting hole 8. The bottom end of the fixing tube 5 is fixedly connected to the threaded tube 9, and the threaded tube 9 is threaded into the fixing hole 11. The bottom end of the threaded tube 9 is fixedly connected to the sensor body 10. The fixing tube 5 serves as a component connecting the flow meter 2 body and the sensor body 10. Signal transmission wires can be arranged inside to ensure stable transmission of flow signals. The protective sleeve 6 on its outer wall provides mechanical protection and can effectively resist physical damage such as external collisions and scratches, extending the service life of the internal components of the flow meter 2.

[0023] Each limiting device includes a spring 16, which is fixedly connected to the inner wall of the mounting groove 15. One end of the spring 16 is fixedly connected to a limiting rod 14, which is slidably connected in the mounting groove 15 and inserted into the corresponding limiting hole 8. Using the elastic thrust of the spring 16, the limiting rod 14 can be automatically pushed into the limiting hole 8 of the protective sleeve 6 after the flow meter 2 is tightened to the position, thus forming a reliable mechanical lock.

[0024] Two movable blocks 13 are fixedly and symmetrically connected to the outer wall of each limiting rod 14, and the two movable blocks 13 are slidably connected in the two corresponding movable slots 12. When disassembling the flow meter 2, the operator only needs to manually move the movable block 13 to compress the spring 16 and make the limiting rod 14 disengage from the limiting hole 8.

[0025] Each fixed block 4 has a protective plate 17 fixedly installed on both sides. The protective plate 17 is L-shaped. The L-shaped protective plate 17 can effectively block dust, liquid and other impurities from entering the moving groove 12 and the mounting groove 15, prevent foreign objects from causing the moving block 13 and the limit rod 14 to jam, and ensure the normal operation of the limit device.

[0026] Multiple anti-slip blocks 7 are fixedly installed on the outer wall of the protective sleeve 6. The multiple anti-slip blocks 7 adopt an anti-slip texture design, which significantly increases the friction when manually rotating the flow meter 2.

[0027] In use, the flow meter 2 is installed on the pipe 1, and the threaded tube 9 is aligned with the fixing hole 11 on the outer wall of the pipe 1. The flow meter 2 is rotated so that the threaded tube 9 is screwed into the fixing hole 11, and the sensor body 10 is sent into the pipe 1. As the flow meter 2 is tightened, the spring 16 in the mounting groove 15 of the fixing block 4 pushes the limiting rod 14, so that it is inserted into the limiting hole 8 on the outer wall of the protective sleeve 6. At the same time, the moving block 13 slides along the moving groove 12 to complete the circumferential fixation of the flow meter 2 and prevent position displacement due to vibration or fluid impact.

[0028] The sensor body 10 is inserted into the pipe 1 to collect fluid flow data in real time and convert the flow signal into an electrical signal. The electrical signal is transmitted to the signal processing module inside the flow meter 2 via the wires inside the fixed pipe 5. After processing, it is converted into a digital flow value and displayed on the display screen 3. The upper limit value H and the lower limit value L of the flow can be set through the operation interface of the display screen 3 or the external communication interface. The threshold parameters are stored in the microprocessor of the flow meter 2.

[0029] The signal processing module continuously compares real-time flow data with preset thresholds. An audible and visual alarm is emitted via the display screen 3, enabling automatic control of the fluid flow rate.

[0030] The protective sleeve 6 wraps around the fixing tube 5, and the anti-slip block 7 on its outer wall increases friction when the flow meter 2 is manually rotated, making installation and operation convenient. The L-shaped protective plate 17 covers the moving grooves 12 on both sides of the fixing block 4 to prevent dust and liquid from entering the limiting device, and to prevent the moving block 13 and the limiting rod 14 from failing to lock due to foreign objects, thus ensuring the stable operation of the flow meter 2.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
