Description

Technical Field

[0001] This utility model relates to the field of heat metering technology, and in particular to an ultrasonic heat meter that is corrosion-resistant and scale-resistant. Background Technology

[0002] With the promotion of national heating metering reform, ultrasonic heat meters have been widely promoted and applied due to their advantages such as high metering accuracy, convenient maintenance, no mechanical parts, and resistance to damage. This type of ultrasonic heat meter includes a hot water flow pipe, an inlet transducer, an outlet transducer, an inlet temperature sensor, and an integrator. The front wall of the hot water flow pipe has inclined mounting holes for the inlet and outlet transducers, which are respectively inserted into these holes. The integrator is mounted on the upper wall of the hot water flow pipe via a bracket and connected to the inlet and outlet transducers. The upper wall of the hot water inlet end of the hot water flow pipe has a mounting hole for the inlet temperature sensor, which is inserted into this hole.

[0003] With prolonged high-temperature use during the heating season, corrosion and scaling on the inner wall of the hot water flow pipe in ultrasonic heat meters become increasingly severe. This is especially true near the pipe wall and orifice edges on the side facing away from the water flow direction, where eddies make it easier for deposits to adhere, leading to severe scaling. This severe scaling not only alters the inner diameter of the hot water flow pipe but also causes irregularities, significantly affecting the metering accuracy of the ultrasonic heat meter. Furthermore, this prolonged scaling also corrodes the inner wall of the hot water flow pipe, impacting the lifespan of the ultrasonic heat meter.

[0004] Therefore, we propose an ultrasonic heat meter that is corrosion-resistant and scale-resistant. Utility Model Content

[0005] The present invention aims to solve the technical problems existing in the prior art and provide an ultrasonic heat meter that is corrosion-resistant and scale-resistant.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an anti-corrosion and anti-scaling ultrasonic heat meter, comprising an ultrasonic heat meter body, a connecting pipe fixedly installed on the left side wall of the ultrasonic heat meter body, a filter box fixedly installed on the left side wall of the connecting pipe, a lifting filter mechanism provided on the inner wall of the filter box, a water inlet pipe fixedly installed on the left side wall of the filter box, and a water outlet pipe fixedly installed on the right side wall of the ultrasonic heat meter body. The lifting filter mechanism includes a mounting frame, and the bottom of the mounting frame is fixedly connected to the top of the filter box.

[0007] Preferably, the inner wall of the mounting bracket is threaded with a threaded rod, and the bottom of the threaded rod is movably connected to the bottom of the inner wall of the filter box.

[0008] Preferably, an adjustment knob is fixedly installed on the top of the threaded rod.

[0009] Preferably, the outer wall of the threaded rod is threadedly connected to a top cover plate at its middle end, and the outer wall of the top cover plate is movably connected to the inner wall of the mounting bracket.

[0012] This invention provides a corrosion-resistant and scale-resistant ultrasonic heat meter. It has the following beneficial effects:

[0013] 1. This corrosion-resistant and scale-resistant ultrasonic heat meter features a lifting and filtering mechanism that filters water entering the body of the ultrasonic heat meter. This effectively prevents impurities from entering the body of the ultrasonic heat meter and causing blockages and corrosion, thus improving the service life and metering accuracy of the ultrasonic heat meter. The lifting and filtering mechanism can be easily controlled by adjusting the knob, threaded rod, and top cover, making it easy to disassemble, replace, and clean the filter screen, ensuring the filtration effect.

[0014] 2. This corrosion-resistant and scale-resistant ultrasonic heat meter, through the setting of a sealing rubber strip, can form a seal between the top cover plate and the filter box, preventing water from seeping out from the gaps and ensuring the airtightness of the filter box.

[0024] Example 1: A corrosion- and scale-resistant ultrasonic heat meter, such as... Figure 1 As shown, the ultrasonic heat meter body 10 includes a connecting pipe 11 fixedly installed on the left side wall of the ultrasonic heat meter body 10, a filter box 12 fixedly installed on the left side wall of the connecting pipe 11, a lifting filter mechanism 13 provided on the inner wall of the filter box 12, a water inlet pipe 14 fixedly installed on the left side wall of the filter box 12, and a water outlet pipe 15 fixedly installed on the right side wall of the ultrasonic heat meter body 10. By setting up the lifting filter mechanism 13, the water entering the ultrasonic heat meter body 10 can be filtered, effectively preventing impurities from entering the ultrasonic heat meter body 10 and causing blockage and corrosion, thus improving the service life and metering accuracy of the ultrasonic heat meter body 10. The lifting filter mechanism 13 can be easily controlled by adjusting the knob 18, the threaded rod 17, and the top cover plate 19, thereby facilitating the disassembly, replacement, and cleaning of the filter screen 21 and ensuring the filtration effect.

[0025] Example 2: Based on Example 1, as follows Figure 2 As shown, the lifting filter mechanism 13 includes a mounting frame 16, the bottom of which is fixedly connected to the top of the filter box 12. A threaded rod 17 is threadedly connected to the inner wall of the mounting frame 16, and the bottom of the threaded rod 17 is movably connected to the bottom of the inner wall of the filter box 12. An adjustment knob 18 is fixedly installed on the top of the threaded rod 17. A top cover plate 19 is threadedly connected to the middle of the outer wall of the threaded rod 17, and the outer wall of the top cover plate 19 is movably connected to the inner wall of the mounting frame 16. Through the sealing rubber strip 20, a seal can be formed between the top cover plate 19 and the filter box 12, preventing water from seeping out from the gaps and ensuring the airtightness of the filter box 12.

[0026] Example 3: Based on Examples 1 and 2, as follows... Figure 2 As shown, a sealing rubber strip 20 is fixedly installed on the bottom outer side of the top cover plate 19, and the bottom of the sealing rubber strip 20 is in movable contact with the top of the filter box 12. A filter screen 21 is fixedly installed at the bottom middle of the top cover plate 19, and the outer wall of the filter screen 21 is movably connected to the inner wall of the filter box 12. The inner wall of the filter screen 21 is movably connected to the outer wall of the threaded rod 17.

[0027] The working principle of this utility model:

[0028] The filter screen 21 can filter impurities in the water, preventing them from entering the interior of the ultrasonic heat meter body 10 and causing blockage. When it is necessary to clean the filter screen 21, the adjustment knob 18 is turned, which drives the threaded rod 17 to rotate. The threaded rod 17 drives the top cover plate 19 to rise on the inner wall of the mounting bracket 16. The top cover plate 19 drives the filter screen 21 to rise on the inner wall of the filter box 12, thereby lifting the filter screen 21 from the filter box 12 for easy cleaning. At the same time, the sealing rubber strip 20 can seal the gap between the top cover plate 19 and the filter box 12 to prevent water leakage and improve the practicality of the device.

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 claims.
