Description

Technical Field

[0001] This utility model relates to the field of ultrasonic heat meter installation technology, specifically a novel valve-controlled ultrasonic heat meter. Background Technology

[0002] Valve-controlled ultrasonic heat meters, as core equipment for individual metering and precise temperature control in heating systems, are widely used in heating pipeline scenarios such as residential and commercial buildings. Their operational stability directly depends on the continuity of data transmission and the integrity of core components. Traditional valve-controlled ultrasonic heat meters have the following shortcomings: (1) The test head, data transmission components, meter body, and control tube of traditional valve-controlled ultrasonic heat meters are mostly integrated fixed structures. Since the components are directly welded or rigidly connected, when local faults such as decreased sensitivity of the test head, short circuit of data line, or poor contact of data connector occur, the faulty component cannot be disassembled separately. The connection between the meter body and the control tube must be completely removed, or even the heating pipeline must be disconnected before maintenance can be carried out. (2) High-temperature fluid in the heating pipeline is prone to seep through the connection gap, which will corrode the surrounding components of the pipeline. At the same time, water vapor in the outdoor humid environment can easily enter the equipment through the data interface and the connection of the mounting plate, directly damaging core components such as test head, data cable, and data connector. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a novel valve-controlled ultrasonic heat meter, which features a detachable structure for easy maintenance and parts replacement, and a targeted sealing design to ensure stable operation. This avoids the problems of cumbersome overall disassembly for maintenance and unstable sealing that can easily damage core components.

[0004] To achieve the goals of a detachable structure for easy maintenance and parts replacement, and a targeted sealing design to ensure stable operation, this utility model provides the following technical solution: A novel valve-controlled ultrasonic heat meter includes a control tube, the top of which is fixedly connected to a mounting base, and the top of the mounting base is fixedly connected to a meter body via a threaded bolt. It also includes: Data interfaces are fixedly connected to both side walls of the meter body, and snap-fit ​​brackets are fixedly connected to both sides of the control tube surface. The data interfaces and snap-fit ​​brackets correspond one-to-one. A mounting plate is snapped onto the surface of the snap-fit ​​bracket, and a test head is fixedly connected to the bottom of the mounting plate. The test head extends into the inner cavity of the control tube. A connecting plate is snapped onto the side wall of the data interface, and a data connector is fixedly connected to the side wall of the connecting plate. The data connector extends into the inner cavity of the data interface and is adapted to the internal terminals of the interface. A data cable is fixedly connected between the data connector and the test head.

[0005] According to some embodiments, the surface of the card holder is provided with a square card slot, and a square sealing ring is fixedly connected to the bottom of the mounting plate, and the square sealing ring can extend into the inner cavity of the square card slot.

[0006] According to some embodiments, the mounting plate surface is threaded with multiple sets of first fixing bolts, and the first fixing bolts can extend into the inner cavity of the snap-fit ​​bracket.

[0007] According to some embodiments, a flange is fixedly connected to the end of the data interface, a circular groove is opened on the surface of the flange, a sealing block is fixedly connected to the side wall of the connecting plate, and the sealing block can extend into the inner cavity of the circular groove.

[0008] According to some embodiments, the side wall of the connecting plate is threaded with multiple sets of second fixing bolts, and the ends of the second fixing bolts pass through the pre-set through holes of the flange and are threadedly engaged with nuts. Beneficial effects

[0009] This utility model provides a novel valve-controlled ultrasonic heat meter, which has the following beneficial effects: (1) The new valve-controlled ultrasonic heat meter has a modular and detachable design for the test head assembly and data transmission assembly. During maintenance, there is no need to disassemble the control tube or meter body as a whole. Only the corresponding fixing bolts need to be unscrewed to remove the mounting plate or connecting plate separately, so as to realize the quick maintenance and replacement of the test head, data connector and data cable. The meter body is detachably connected to the mounting base through the threaded bolts. It can also be easily separated during the overall maintenance, reducing pipeline downtime and reducing maintenance manpower and material costs. (2) In this new type of valve-controlled ultrasonic heat meter, the clamping frame and the mounting plate are sealed by a square sealing ring embedded in a square slot, and the data interface and the connecting plate are sealed by a sealing block embedded in a round groove. The double sealing structure can effectively prevent fluid leakage in the pipeline and external water vapor intrusion, which not only protects the core components such as the test head and data line from corrosion, but also avoids interruption or error in data transmission due to environmental interference, thus ensuring the stability of heat metering and valve control command output.

It also includes: Data interfaces 2 are fixedly connected to both sides of the body 102. A snap-fit ​​bracket 201 is fixedly connected to both sides of the surface of the control tube 1, with each data interface 2 and snap-fit ​​bracket 201 corresponding to the other. A mounting plate 202 is snapped onto the surface of the snap-fit ​​bracket 201. A test head 203 is fixedly connected to the bottom of the mounting plate 202, extending into the inner cavity of the control tube 1. A connecting plate 204 is snapped onto the side wall of the data interface 2, and a data connector 205 is fixedly connected to the side wall of the connecting plate 204. The data connector 205 extends into the inner cavity of the data interface 2 and is adapted to the internal terminals of the interface. A data cable 206 is fixedly connected between the data connector 205 and the test head 203. The surface of the clip bracket 201 is provided with a square slot 3, and the bottom of the mounting plate 202 is fixedly connected with a square sealing ring 301, which can extend into the inner cavity of the square slot 3. The mounting plate 202 has multiple sets of first fixing bolts 302 threadedly connected to its surface, and the first fixing bolts 302 can extend into the inner cavity of the snap-fit ​​bracket 201; A flange 4 is fixedly connected to the end of the data interface 2. A circular groove 401 is opened on the surface of the flange 4. A sealing block 402 is fixedly connected to the side wall of the connecting plate 204, and the sealing block 402 can extend into the inner cavity of the circular groove 401. The connecting plate 204 has multiple sets of second fixing bolts 403 threadedly connected to its side wall, and the ends of the second fixing bolts 403 pass through the pre-set through holes of the flange 4 and are threadedly engaged with nuts. Installation steps: Connect the control pipe 1 to the preset interface of the heating pipe, ensure that the fluid passage inside the control pipe 1 is unobstructed, align the mounting base 101 on the top of the control pipe 1 with the mounting surface on the bottom of the meter body 102, and tighten the threaded bolts in sequence to achieve a detachable connection between the meter body 102 and the control pipe 1. After installation, the data interfaces 2 on both sides of the meter body 102 correspond one-to-one with the snap-fit ​​brackets 201 on both sides of the control pipe 1. Pick up the mounting plate 202 and align the square sealing ring 301 at its bottom with the square slot 3 on the surface of the snap-fit ​​bracket 201. Snap the mounting plate 202 onto the snap-fit ​​bracket 201, ensuring that the square sealing ring 301 is fully embedded in the inner cavity of the square slot 3. Use the first fixing bolt 302 to fix the mounting plate 202 and the snap-fit ​​bracket 201. At this time, the test head 203 has penetrated the side wall of the control tube 1 and extended into the inner cavity for collecting fluid parameters. Pick up the connecting plate 204 and align the sealing block 402 on its side wall with the circular groove 401 of the flange 4 at the end of the data interface 2. Snap the connecting plate 204 onto the side wall of the data interface 2, ensuring that the sealing block 402 is fully embedded in the circular groove 401 to achieve a seal at the data interface 2.

[0014] Operation process: When the fluid in the heating pipeline flows through the inner cavity of the control pipe 1, the test head 203 collects the core parameters of the fluid such as flow rate and temperature in real time. The collected parameters are transmitted to the data connector 205 through the data cable 206 and then transmitted to the meter body 102 through the data interface 2. After processing and calculating the data, the meter body 102 completes the heat metering and valve control command output. The valve control function is implemented based on the native program of the meter body 102 and requires no additional operation. At the same time, during operation, the square sealing ring 301 and the sealing block 402 respectively seal the connection between the mounting plate 202 and the snap bracket 201, and the connection plate 204 and the flange 4 to prevent fluid leakage in the pipeline or external water vapor intrusion and ensure stable data transmission. Meanwhile, when the test head 203 needs to be repaired or replaced: unscrew the first fixing bolt 302, and directly remove the mounting plate 202 upwards to repair or replace the test head 203 without disassembling the control tube 1 or the meter body 102. When the data transmission component needs to be repaired: unscrew the matching nut of the second fixing bolt 403, pull out the second fixing bolt 403, remove the connecting plate 204, and the data connector 205 or data cable 206 can be maintained. The operation is convenient. When the entire meter body 102 needs to be overhauled: unscrew the threaded bolt on the mounting base 101 to separate the meter body 102 from the control tube 1. After the overhaul is completed, reset it in reverse according to the installation steps.
