Description

Technical Field

[0001] The utility model relates to the technical field of liquid flow meters, in particular to a novel liquid flow metering and detecting device. Background Art

[0002] Liquid flowmeter is a precision instrument manufactured based on the Karman vortex principle and used to measure the flow of liquid, gas and steam in sealed pipes. Since the detection element is sealed in the detection body, it is not measured by the medium, and there are no moving parts inside, and no on-site maintenance is required, it is highly respected by the majority of users and is widely used in measurement management and process control in textile printing and dyeing, petroleum, chemical industry, metallurgy and pharmaceuticals, thermal power, papermaking, and fire protection industries.

[0003] Among them, the Chinese patent publication number CN213810054U discloses a liquid flow metering and detection device, which fixes the metering display in the box structure for protection and dust prevention, and the box can be easily opened through the cover body, which is convenient for reading the metering and detection device. The cover body of the liquid flow metering and detection device is provided with a transparent display window, which can conveniently read the metering display outside the box body. Although the box body can protect the metering display, it does not protect the mounting rod. The mounting rod is exposed to the outside and is easily damaged by impact. At the same time, a lot of dust will still adhere to the surface of the box cover after a long time, making the display window unable to be observed. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0021] See also Figure 1-2The utility model provides a technical solution: a new type of liquid flow metering and detection device, including a metering and detection box 3, which is specifically a rectangular structure. A connecting pipe 2 is fixedly connected to the bottom of the metering and detection box 3. A metering display 4 is installed at one end of the connecting pipe 2 located inside the metering and detection box 3. A connecting flange 1 is connected to the other end of the connecting pipe 2. The connecting flange 1 is used for fixed connection with a pipeline. A protective component for protecting the connecting pipe 2 is also provided between the metering and detection box 3 and the connecting flange 1.

[0022] The protective component includes a fixed cover 7, a protective cover 8 and a fixed block 9. Two fixed blocks 9 are provided. The two fixed blocks 9 are fixedly installed on the surface of the connecting flange 1. The fixed block 9 can be installed on the surface of the connecting flange 1 by bolting or welding. The fixed cover 7 is cylindrical in structure. The protective cover 8 is fixedly installed on the bottom of the fixed cover 7. The inner diameters of the fixed cover 7 and the protective cover 8 are both larger than the diameter of the connecting pipe 2 to ensure that they can be covered on the surface of the connecting pipe 2 to complete the protection of the connecting pipe 2. The protective cover 8 is specifically made of flexible rubber material, and the bottom of the protective cover 8 fits with the surface of the connecting flange 1, so that it can play a sealing and protective role on the connecting pipe 2 to a certain extent, and prevent the connecting pipe 2 from being affected by water vapor and causing rust.

[0023] A box cover 5 is hinged on the surface of the metering and detection box 3, and a visual observation window 6 for conveniently observing the metering display 4 is embedded on the surface of the box cover 5. A protective glass is embedded on the surface of the visual observation window 6 to facilitate data observation. A dustproof plate 10 is also hinged on the surface of the box cover 5, and a torsion spring is also sleeved on the hinge axis of the dustproof plate 10. The dustproof plate 10 is specifically a rectangular plate-shaped structure, and a sealing ring is glued and fixed at the position where the dustproof plate 10 and the surface of the box cover 5 are in contact. The sealing ring can ensure that the visual observation window 6 is sealed to prevent dust from entering the interior and causing dust to adhere to the surface of the visual observation window 6.

[0024] Working principle: When in use, during installation, fix the device on the pipeline through the connecting flange 1, then cover the metering detection box 3 on the surface of the metering display 4, and make the fixed cover 7 just fit on the surface of the fixed block 9, then fix the fixed cover 8 to the fixed block through bolts to complete the installation of the metering display 4. When it is necessary to observe the reading of the metering display 4, you only need to open the dustproof plate 10 to observe the reading through the visual observation window 6, and it can avoid the situation where dust adheres to the surface of the visual observation window 6 due to long-term use.
