In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application.
The embodiment of the application discloses a variable throat diameter flowmeter.
Referring to fig. 1 and 2, the variable throat flowmeter includes:
the flowmeter comprises a flowmeter main body 101, a limiting fixed block 102 and a replaceable inner core 103;
an inner runner mounting hole, an anti-rotation positioning hole and a limiting fixing internal thread are formed in the flowmeter body 101;
the replaceable inner core 103 is provided with inner Venturi pipes with different throat diameters and an anti-rotation positioning pin 201;
the outer surface of the limiting fixing block 102 is provided with a limiting fixing external thread matched with the flowmeter main body 101;
the replaceable inner core 103 is inserted into an inner flow passage mounting hole of the flowmeter body 101, the anti-rotation positioning pin 201 is matched with the anti-rotation positioning hole, the limiting fixing block 102 is matched with the limiting fixing inner thread of the flowmeter body 101 through a limiting fixing outer thread, and the inner end face of the limiting fixing block 102 abuts against the replaceable inner core 103.
The implementation principle of the embodiment is as follows:
the variable throat flowmeter comprises a flowmeter body 101, a limiting fixing block 102 and a replaceable inner core 103, wherein an inner runner mounting hole, an anti-rotation positioning hole and a limiting fixing inner thread are formed in the flowmeter body 101, the replaceable inner core 103 is provided with inner venturi pipes with different throat diameters and an anti-rotation positioning pin 201, and a limiting fixing outer thread matched with the flowmeter body 101 is arranged on the outer surface of the limiting fixing block 102;
when the throat diameter changeable flowmeter works, the replaceable inner core 103 which meets the flow range is selected to be inserted into the flow channel mounting hole in the flowmeter body 101, and the anti-rotation positioning pin 201 is matched with the anti-rotation positioning hole to prevent the replaceable inner core 103 from changing in position during installation or use;
the limiting fixing block 102 is matched with the limiting fixing internal thread of the flowmeter main body 101 through the limiting fixing external thread, and the inner end face of the limiting fixing block 102 abuts against the replaceable inner core 103 to realize limiting and fixing of the replaceable inner core;
due to the use of the replaceable inner core 103 of the inner Venturi tube with different throat diameters, the requirement that the replaceable inner core 103 of the inner Venturi tube with the corresponding throat diameter is replaced under different flow ranges of the flowmeter can be met, and the flowmeter main body 101 does not need to be replaced.
In combination with the above-described embodiments, preferably, the inner end surface of the limit fixing block 102 is provided with an O-ring groove, and the O-ring groove is provided with an O-ring 104, so that the medium leakage can be prevented.
In combination with the above-described embodiment, preferably, the flowmeter body 101 is further provided with a photon probe 105, the internal venturi conduits capable of replacing different throat diameters of the inner core 103 include a throat section, an inner diameter changing section and an inner diameter unchanging section, a photon probe through hole 202 is arranged at a position of the throat section corresponding to the photon probe 105, a photon source groove 203 is arranged at a position of the throat section corresponding to the photon probe through hole 202, and a plurality of groups of energy level groups of photon sources 106 are arranged in the photon source groove 203. Because the multiple groups of energy level groups of the light quantum sources 106 are arranged in the light quantum source grooves 203 of the replaceable inner core 103, and are embedded, and the light quantum probe through holes 202 are arranged, the light quantum probes 105 can correspond to the light quantum sources 106, and the multiphase flow detection of the medium flowing through the throat section can be realized.
The multi-energy-level group photon source takes the four groups of energy-level group photon sources as the example of the Ba-133 exempt-level isotope photon source, and generates single photons of the four groups of energy-level groups with energies of 31keV, 81keV, 160keV and 356 keV. The known Ba-133 photon source, with a radioactivity of 25 microcentrites, can emit nearly one million single photons per second of an energy group of 31keV, 81keV, 160keV and 356keV, and the phase fraction measurement of the mixed-phase fluid is done by measuring the energy of each photon, depending on the photoelectric cross-section of the material and the photon sub-group of energies of 31keV and 81keV and the compton cross-section of the material and the photon sub-group of energies of 160keV and 356 keV. A photon, photon for short, is a fundamental particle for transmitting electromagnetic interactions, and is a canonical boson. Photons are carriers of electromagnetic radiation, whereas in quantum-field theory photons are considered as mediators of electromagnetic interactions. The stationary mass of a photon is zero compared to most elementary particles, which means that its propagation speed in vacuum is the speed of light. Like other quanta, photons have a wave-particle duality: photons can show the properties of refraction, interference, diffraction and the like of classical waves; and the particle nature of photons can be represented by the photoelectric effect, compton scattering and electron pair effect. Photons can only transmit quantized energy, are lattice particles, and are mass-energy phase states of ring quantum particles. The amount of energy of a photon is proportional to the frequency of the light, and the higher the frequency, the higher the energy. When a photon is absorbed by an atom, there is an electron that gains sufficient energy to transit from the inner orbital to the outer orbital, and the atom with the electron transition changes from the ground state to an excited state, i.e., the photoelectric effect.
In connection with the above-described embodiments, it is preferable that the outer surface of the replaceable inner core 103 is provided with two O-ring grooves 204, the two O-ring grooves 204 are disposed at two sides of the through hole 202 of the optical quantum probe, and the O-ring 104 is disposed in each of the two O-ring grooves 204, so as to prevent the medium from leaking.
In connection with the above-described embodiment, it is preferable that the internal diameter of the limit fixing block 102 is the same as the internal diameter of the section with the constant internal diameter of the replaceable core 103, so that the limit fixing block 102 can perform limit fixing on the replaceable core 103 without affecting the flow rate of the medium flowing from the limit fixing block 102 to the replaceable core 103.
In conclusion, compared with the flowmeter main body of the conventional flowmeter, the variable throat diameter flowmeter can meet the requirements of the flowmeter on different flow ranges only by replacing the replaceable inner cores of the inner Venturi tubes with different throat diameters without replacing the flowmeter main body.
The foregoing is a preferred embodiment of the present application and is not intended to limit the scope of the application in any way, and any features disclosed in this specification (including the abstract and drawings) may be replaced by alternative features serving equivalent or similar purposes, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.
