Description

Technical Field

[0001] This utility model relates to the field of heat metering technology, and in particular to a steady-flow, scale-resistant ultrasonic heat meter. 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 of the transducer at the inlet and outlet ends, and near the inlet temperature sensor, which are facing away from the water flow direction. Due to the presence of eddies, deposits are more easily adhered, leading to severe scaling. This severe scaling not only alters the inner diameter of the hot water flow pipe but also causes irregularities in its inner diameter, naturally and seriously affecting the metering accuracy of the ultrasonic heat meter.

[0004] Therefore, we propose a steady-flow, scale-inhibiting ultrasonic heat meter. Utility Model Content

[0005] The present invention aims to solve the technical problems existing in the prior art and provide a steady-flow and scale-resistant ultrasonic heat meter.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a flow-stabilizing and scale-inhibiting ultrasonic heat meter, comprising a flow-stabilizing component, a sealing cover movably installed on the right side wall of the flow-stabilizing component, a filter cylinder threadedly connected to the outer right side of the sealing cover, a scale-inhibiting component provided on the inner wall of the filter cylinder, a connecting pipe fixedly installed on the right side wall of the filter cylinder, an ultrasonic heat meter body fixedly installed on the right side wall of the connecting pipe, and a water outlet pipe fixedly installed on the right side wall of the ultrasonic heat meter body. The flow-stabilizing component includes a water inlet bend, and the right side wall of the water inlet bend is movably connected to the left side wall of the sealing cover. The scale-inhibiting component includes a filter metal mesh layer, and the outer wall of the filter metal mesh layer is movably connected to the inner wall of the filter cylinder.

[0007] Preferably, multiple inclined baffles are evenly fixed to the inner wall of the water inlet bend.

[0008] Preferably, a filter sponge layer is fixedly installed on the right side wall of the filter metal mesh layer.

[0009] Preferably, the outer wall of the filter sponge layer is movably connected to the inner wall of the filter cylinder.

[0010] Preferably, an activated carbon adsorption layer is fixedly installed on the right side wall of the filter sponge layer.

[0011] Preferably, the outer wall of the activated carbon adsorption layer is movably connected to the inner wall of the filter cartridge.

[0012] This invention provides a steady-flow, scale-inhibiting ultrasonic heat meter. It has the following beneficial effects:

[0013] 1. This type of flow-stabilizing and scale-inhibiting ultrasonic heat meter, by incorporating a flow-stabilizing component and a scale-inhibiting component, effectively stabilizes the water flow entering the ultrasonic heat meter body and inhibits scale formation. The inlet bend and its inclined baffle design in the flow-stabilizing component slow down the water flow velocity, reduce eddy current generation, and make the water flow more stable, avoiding the problems of sediment adhesion and scale formation caused by eddy currents. The filter metal mesh layer, filter sponge layer, and activated carbon adsorption layer in the scale-inhibiting component can filter and adsorb impurities, particulate matter, and harmful substances in the water step by step, further preventing scale formation and corrosion. This not only improves the metering accuracy of the ultrasonic heat meter but also extends its service life and reduces maintenance costs, resulting in significant economic and social benefits.

[0014] 2. This type of steady flow and scale-inhibiting ultrasonic heat meter, with its sealing cover, allows for easy inspection or replacement of the scale-inhibiting components inside the filter cartridge, effectively preventing water leakage and ensuring the normal operation of the equipment. At the same time, the threaded connection design between the sealing cover and the filter cartridge makes disassembly and installation more convenient, improving the maintenance efficiency of the equipment.

[0025] Example 1: A steady-flow, scale-inhibiting ultrasonic heat meter, such as... Figure 1 As shown, the device includes a flow stabilizing component 10. A sealing cover 11 is movably installed on the right side wall of the flow stabilizing component 10. A filter cylinder 12 is threadedly connected to the right side of the outer wall of the sealing cover 11. A scale inhibitor component 13 is provided on the inner wall of the filter cylinder 12. A connecting pipe 14 is fixedly installed on the right side wall of the filter cylinder 12. An ultrasonic heat meter body 15 is fixedly installed on the right side wall of the connecting pipe 14. A water outlet pipe 16 is fixedly installed on the right side wall of the ultrasonic heat meter body 15. By setting the flow stabilizing component 10 and the scale inhibitor component 13, the water flow entering the ultrasonic heat meter body 15 can be effectively stabilized and scale inhibited. The design of the inlet bend 17 and the inclined baffle 18 on the inner wall of the flow component 10 can slow down the water flow speed, reduce the generation of eddies, and make the water flow more stable, avoiding the problems of sediment adhesion and scaling caused by eddies. The filter metal mesh layer 19, filter sponge layer 20 and activated carbon adsorption layer 21 in the scale inhibition component 13 can filter and adsorb impurities, particulate matter and harmful substances in the water step by step, further preventing scaling and corrosion. This not only improves the metering accuracy of the ultrasonic heat meter, but also extends its service life and reduces maintenance costs, resulting in significant economic and social benefits.

[0026] Example 2: Based on Example 1, as follows Figure 2As shown, the flow stabilizing component 10 includes an inlet bend 17, and the right side wall of the inlet bend 17 is movably connected to the left side wall of the sealing cover 11. Multiple inclined baffles 18 are evenly fixed on the inner wall of the inlet bend 17. By setting the sealing cover 11, it is convenient to inspect or replace the scale inhibitor component 13 inside the filter cartridge 12, effectively preventing water leakage and ensuring the normal operation of the equipment. At the same time, the threaded connection design between the sealing cover 11 and the filter cartridge 12 makes disassembly and installation more convenient and improves the maintenance efficiency of the equipment.

[0027] Example 3: Based on Examples 1 and 2, as follows... Figure 3 As shown, the scale inhibition assembly 13 includes a filter metal mesh layer 19, and the outer wall of the filter metal mesh layer 19 is movably connected to the inner wall of the filter cylinder 12. A filter sponge layer 20 is fixedly installed on the right side wall of the filter metal mesh layer 19, and the outer wall of the filter sponge layer 20 is movably connected to the inner wall of the filter cylinder 12. An activated carbon adsorption layer 21 is fixedly installed on the right side wall of the filter sponge layer 20, and the outer wall of the activated carbon adsorption layer 21 is movably connected to the inner wall of the filter cylinder 12.

[0028] The working principle of this utility model is as follows: When hot water flows through the inlet bend 17, the inclined baffle 18 creates a vortex during the flow. The presence of the vortex reduces the direct impact of the water flow, thus achieving a stable flow effect. Simultaneously, the vortex promotes impurities and particles in the water to move closer to the pipe wall under centrifugal force, facilitating subsequent filtration. The water then enters the filter cylinder 12, first passing through the filter metal mesh layer 19, which blocks larger impurities and particles, protecting subsequent filter layers from clogging. Next, the water passes through the filter sponge layer 20, which has a fine pore structure to further remove tiny particles and suspended solids. Finally, the water passes through the activated carbon adsorption layer 21, which utilizes the adsorption properties of activated carbon to remove organic matter, residual chlorine, and other harmful substances from the water, improving water quality. After treatment by the scale inhibitor component 13, the water becomes cleaner and more stable before entering the ultrasonic heat meter body 15 for heat measurement. Due to the improved stability of the water flow and the enhanced water quality, the metering accuracy of the ultrasonic heat meter body 15 is significantly improved, while errors caused by scaling are reduced. Finally, the metered water flows out from the outlet pipe 16, completing the entire heating metering process. This flow-stabilizing and scale-inhibiting ultrasonic heat meter, through the combined use of flow-stabilizing and scale-inhibiting components, achieves both flow stabilization and scale inhibition for hot water supply, improving the metering accuracy and service life of the ultrasonic heat meter, and has broad application prospects.

[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 claims.
