Pipe-electric separation type ultrasonic water meter and heat meter Technical Field
[0001] This invention belongs to the field of electronic instruments and meters, and specifically relates to a tube-electric separation type ultrasonic water meter and heat meter. Background Technology
[0002] Currently, electronic instruments used in various places, especially ultrasonic water meters and heat meters for fluid measurement, have many defects due to their complex structure. Moreover, the complex production process leads to high production costs.
[0003] This invention provides a solution for a pipe-electric separation ultrasonic water meter and heat meter, which not only simplifies the production of ultrasonic water meters and heat meters but also reduces production costs. Summary of the Invention
[0004] The invention is implemented as follows: One or more pairs of elliptical through holes are made on one surface of a circular or rectangular hollow pipe segment assembly. An inlet pipe and an outlet pipe are connected to both ends of the pipe segment assembly (flanges can also be connected to both ends of the pipe segment). Alternatively, a valve pipe and a generator pipe can be connected between the pipe segment assembly and the inlet and outlet pipes. A V-shaped ultrasonic transducer fixing assembly is installed at the upper end of the pipe segment assembly with the elliptical through holes. This V-shaped ultrasonic transducer fixing assembly is an ultrasonic transducer made of metal or non-metal. The ultrasonic transducer mounting base consists of two inner tubes forming a V-shape with an angle of α, into which two ultrasonic transducers are housed. A pair of ultrasonic transducers are installed within this base, and side sealing rings are mounted on the transducers. Ultrasonic transducer fixing adhesive is applied to the tail of each transducer. A soft sealing gasket of the same shape and size as the tube section is placed between them. Screws are used to secure the V-shaped ultrasonic transducer mounting assembly to the tube section assembly, compressing the soft sealing gasket to create a complete seal. A sealed electronic box assembly is then fixed on top. This electronic box assembly comprises an electronic box body, a valve control actuator made of a micro motor and gears, a main control circuit board made of computer and communication chips, a generator coil, a grooved sealing ring, a wedge-shaped sealing top cover, and an electronic box top cover.
[0005] When this invention is installed in the pipeline requiring measurement, as fluid flows through it, an ultrasonic transducer traveling with the water flow emits an ultrasonic beam. This ultrasonic beam is reflected off the inner wall opposite the pipe section assembly and then onto another ultrasonic transducer at an angle to it. This transducer converts the ultrasonic beam into an electrical signal. Conversely, this transducer emits an ultrasonic beam in the opposite direction, which is also reflected off the inner wall opposite the pipe section assembly and then onto another ultrasonic transducer at an angle to it, also converting the ultrasonic beam into an electrical signal. A computer chip analyzes these two ultrasonic beams, calculates the time difference during their propagation, and uses this time difference to calculate the velocity of the fluid flowing through the invention, thus determining the velocity of the fluid passing through it.
[0006] In this invention, a valve ball or a generator impeller assembly can be connected to the pipe section assembly, so that there is no need to power the circuit board with a dedicated battery, but the power can be generated by the flow of the fluid medium; the fluid medium in the pipe section can also be opened or closed by the rotation of the valve ball, and the size of the fluid medium can be controlled by a fixed value.
[0007] In the production of this invention, the pipe section assembly, the V-shaped ultrasonic transducer fixing assembly, the soft sealing ring, and the electronic box assembly can be manufactured separately and independently. Then, they can be connected by simple screws to form an ultrasonic water meter and a heat meter, which greatly simplifies the production of this invention and reduces its production cost.

[0020] The invention is implemented as follows: one or more pairs of elliptical through holes are made on one surface of a circular hollow pipe segment or a rectangular hollow pipe segment assembly (6). An inlet pipe (1) and an outlet pipe (25) are connected to both ends of the pipe segment assembly (6) (flanges can also be connected to both ends of the pipe segment). At the same time, a valve pipe and a generator pipe can be connected between the pipe segment assembly (6) and the inlet pipe (1) and the outlet pipe (25). A V-shaped ultrasonic transducer fixing assembly is installed at the upper end of the pipe segment assembly (6) with the elliptical through holes. The V-shaped ultrasonic transducer fixing assembly is an ultrasonic transducer fixing base made of metal or non-metal. (16) The ultrasonic transducer base (16) is a part in which two inner tubes that can be installed into ultrasonic transducers (17) are made into a V-shaped angle with an angle of a. A pair of ultrasonic transducers (17) are installed inside, and a side sealing ring is installed on the ultrasonic transducer (17). An ultrasonic transducer fixing adhesive (18) is installed at the tail of the ultrasonic transducer (17). A soft sealing gasket (15) of the same shape and size as the pipe section is placed between them. The V-shaped ultrasonic transducer fixing assembly is fixed to the pipe section assembly (6) with screws and the soft sealing gasket (15) between them is compressed to make it a complete seal. Then a sealed electronic box assembly is fixed on top. The electronic box assembly consists of an electronic box body (24), a micro motor (9), a valve control actuator made of gears, a main control circuit board (19) made of computer chips and communication chips, a generator coil (22), a grooved sealing ring (21), a wedge-shaped sealing top cover (13), and an electronic box top cover (12).
[0021] When this invention is installed in the pipeline to be measured, when a fluid medium flows through the invention, the ultrasonic transducer (17) following the water flow emits a beam of ultrasonic waves. Upon encountering the inner wall opposite the pipe section assembly (6), the ultrasonic waves are reflected to another ultrasonic transducer (17) at an angle to it. This ultrasonic transducer (17) converts the ultrasonic waves into an electrical signal. Conversely, this ultrasonic transducer (17) emits a beam of ultrasonic waves in the opposite direction. This beam of ultrasonic waves also reflects to another ultrasonic transducer (17) at an angle to it upon encountering the inner wall opposite the pipe section assembly (6). This ultrasonic transducer (17) also converts the ultrasonic waves into an electrical signal. The computer chip analyzes these two ultrasonic beams and calculates the time difference during their propagation. Using this time difference, the velocity of the fluid medium flowing through the invention can be calculated, thus determining the velocity of the fluid medium flowing through the invention.
[0022] In this invention, a valve ball (3) or a generator impeller assembly can be connected to the pipe section assembly (6), so that there is no need to carry a dedicated battery to power its circuit board, but the power can be generated by the flow of fluid medium; the fluid medium in the pipe section can also be opened or closed by the rotation of the valve ball (3) and the size of the fluid medium can be controlled.
[0023] In the production of this invention, the pipe section assembly, the V-shaped ultrasonic transducer fixing assembly, the soft sealing ring (15) and the electronic box assembly can be produced separately and independently. Then, they can be connected by simple screws (20) to become ultrasonic water meters and heat meters, which greatly simplifies the production of this invention. At the same time, its production cost is also reduced.
