Description

Technical Field

[0001] This utility model relates to the field of heating pipeline control valve technology, specifically an ultrasonic heat meter with flow regulation function that is simple in structure, has good monitoring effect, small size, and occupies little space. Background Technology

[0002] As is well known, flow and temperature monitoring are required on heating pipelines. Flow is typically achieved using ultrasonic heat meters, while temperature is achieved using temperature sensors. The distance between the ultrasonic heat meter and the control valve on the heating pipeline is generally greater than 10 times the pipe diameter in front and greater than 5 times the pipe diameter behind to ensure accurate monitoring. However, due to space constraints during the installation of heating pipelines, it is impossible to install ultrasonic heat meters and control valves simultaneously. Therefore, ultrasonic heat meters with flow control functions are not available. Existing flow monitoring uses ultrasonic heat meters, whose reflectors are fixed to the inner wall of the pipe using a reflector frame. Because the reflector is disassembled and installed on the reflector frame, fluid impact can easily cause the reflector to detach from the frame. Furthermore, over time, dirt in the fluid can accumulate on the reflector, leading to inaccurate data transmission and affecting monitoring performance. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an ultrasonic heat meter with flow regulation function that is simple in structure, has good monitoring effect, small size, and occupies little space.

[0004] The technical solution adopted by this utility model to solve its technical problem is: An ultrasonic heat meter with flow regulation function is provided, comprising a tube body, characterized in that the tube body includes a first speed-increasing tube body, a front flow transceiver tube body, a second speed-increasing tube body, a rear flow transceiver tube body, and a valve mounting tube body. The diameter of the first speed-increasing tube body is larger than the diameter of the front flow transceiver tube body, the diameter of the front flow transceiver tube body is larger than the diameter of the second speed-increasing tube body, the diameter of the rear flow transceiver tube body is equal to the diameter of the front flow transceiver tube body, and the diameter of the valve mounting tube body is equal to the diameter of the first speed-increasing tube body. The inlet of the first speed-increasing tube body is a liquid inlet, and the outlet of the valve mounting tube body is a liquid outlet. A ball valve and a temperature sensor interface are installed on the valve mounting tube body, and ultrasonic transceiver devices are respectively installed on the front flow transceiver tube body and the rear flow transceiver tube body.

[0005] The present invention provides reflectors on the inner walls of the front and rear flow transceiver tubes. The reflectors are fixed to the inner walls of the front and rear flow transceiver tubes by reflector frames. The reflector frames are plate-shaped structures, and the reflectors are connected to the plate-shaped reflector frames at a 45° angle. The inner walls of the front and rear flow transceiver tubes are symmetrically provided with strip-shaped insertion slots. The two sides of the reflector frames are inserted into the inner walls of the front and rear flow transceiver tubes through the strip-shaped insertion slots, and the reflectors are inserted into the positions corresponding to the ultrasonic transceiver devices.

[0007] The inner diameter of the first speed-increasing tube body described in this utility model is 1.2-1.5 times the diameter of the front flow transceiver tube body and the rear flow transceiver tube body, and the diameter of the front flow transceiver tube body and the rear flow transceiver tube body is 1.5-1.8 times the diameter of the second speed-increasing tube body.

[0008] The reflector and reflector frame described in this utility model are an integral structure. The plate-shaped reflector frame is symmetrically provided with arc-shaped grooves. The circular reflector plate in the arc-shaped groove is rotated 45° to form a reflector. The reflector and reflector frame have high connection strength, which avoids the fluid in the pipeline from impacting the reflector and causing it to detach from the reflector frame.

[0013] The present invention will be further described below with reference to the accompanying drawings: As shown in the attached figure, an ultrasonic heat meter with flow control function is provided with a tube body. The tube body comprises a first speed-increasing tube body 1, a front flow transceiver tube body 2, a second speed-increasing tube body 3, a rear flow transceiver tube body 4, and a valve mounting tube body 5. The diameter of the first speed-increasing tube body 1 is larger than the diameter of the front flow transceiver tube body 2, the diameter of the front flow transceiver tube body 2 is larger than the diameter of the second speed-increasing tube body 3, the diameter of the rear flow transceiver tube body 4 is equal to the diameter of the front flow transceiver tube body 2, and the diameter of the valve mounting tube body 5 is equal to the diameter of the first speed-increasing tube body 1. The inlet of the first speed-increasing tube body 1 is a liquid inlet 6, and the outlet of the valve mounting tube body 5 is a liquid outlet 7. A ball valve 8 and a temperature sensor interface 9 are installed on the valve mounting tube body 5. Ultrasonic transceiver devices 10 are respectively installed on the front flow transceiver tube body 2 and the rear flow transceiver tube body 4.

[0014] Furthermore, a reflector 11 is provided on the inner wall of the front flow transceiver tube 2 and the rear flow transceiver tube 4. The reflector 11 is fixed on the inner wall of the front flow transceiver tube 2 and the rear flow transceiver tube 4 by a reflector frame 12. The reflector frame 12 is a plate-shaped structure. The reflector 11 is connected to the plate-shaped reflector frame 12 at a 45° angle. The inner wall of the front flow transceiver tube 2 and the rear flow transceiver tube 4 is symmetrically provided with strip-shaped insertion slots 13. The two sides of the reflector frame 12 are inserted into the inner wall of the front flow transceiver tube 2 and the rear flow transceiver tube 4 through the strip-shaped insertion slots 13, and the reflector 11 is inserted into the position corresponding to the ultrasonic transceiver device 10.

[0015] Furthermore, the first speed-increasing pipe body 1 is connected to the front flow transceiver pipe body 2, the front flow transceiver pipe body 2 is connected to the second speed-increasing pipe body 3, the second speed-increasing pipe body 3 is connected to the rear flow transceiver pipe body 4, and the rear flow transceiver pipe body 4 is connected to the valve installation pipe body 5 via transition pipe bodies 14, and the inner wall slope of the transition pipe body 14 is an inclined surface.

[0016] Furthermore, the inner diameter of the first speed-increasing tube 1 is 1.2-1.5 times the diameter of the front flow transceiver tube 2 and the rear flow transceiver tube 4, and the diameter of the front flow transceiver tube 2 and the rear flow transceiver tube 4 is 1.5-1.8 times the diameter of the second speed-increasing tube 3.

[0017] Furthermore, the reflector 11 and the reflector frame 12 are an integral structure. The plate-shaped reflector frame 12 is symmetrically provided with arc-shaped grooves 15. The circular reflector plate in the arc-shaped groove 15 is rotated 45° to form the reflector 11. The reflector 11 is integrally connected to the reflector frame 12 via the connecting part 16. The connection strength between the reflector 11 and the reflector frame 12 is high, which avoids the fluid in the pipeline from impacting the reflector 11 and causing it to detach from the reflector frame 12.

[0018] In use, this invention saves space by mounting the control valve and the ultrasonic transceiver 10 on a single pipe body, while ensuring the accuracy of the ultrasonic heat meter's measurement data and enabling temperature monitoring. The ultrasonic heat meter includes the ultrasonic transceiver 10, a reflector 11, and a reflector frame 12. Other structures and connections are the same as in existing technologies and will not be described in detail here. Furthermore, in this design, the reflector 11 and reflector frame 12 are integrally connected. The reflector frame 12 has a plate-like structure, reducing its impact on fluid flow resistance. The reflector frame 12 is fixed to the closed end via a strip-shaped insertion groove 13. The opening of the strip-shaped insertion groove 13 is located at the end of the inclined surface of the transition pipe body 14, facilitating the removal and insertion of the reflector frame 12 and the cleaning of dirt adhering to the reflector frame 12 and the reflector 11. Cleaning is performed while the reflector 12 and reflector 11 are integrated, preventing the reflector 11 from falling off and ensuring the monitoring effect. The reflector 12 and reflector 11 on the inner wall of the front flow transceiver pipe 2 can be directly removed for cleaning or replacement via the side liquid inlet 6. The reflector 12 and reflector 11 on the rear flow transceiver pipe 4 can be cleaned or replaced by removing the valve core of the control valve and removing it via the liquid outlet 7 of the valve installation pipe 5. The valve core of the control valve is then reinstalled for use. The control valve is a ball valve, which reduces the impact of the fluid on the reflector during flow regulation, thus ensuring the accuracy of the ultrasonic heat meter's detection. This invention, due to its structure, has advantages such as simple structure, good monitoring effect, small size, and minimal space occupation.
