Description

Technical Field

[0001] This utility model relates to the field of vortex flow meter technology, specifically to an ultra-low temperature vortex flow meter. Background Technology

[0002] Traditional vortex flowmeters are prone to measurement accuracy fluctuations due to sudden drops in medium temperature under low-temperature conditions, and lack an active heating and regulation mechanism, making them unsuitable for complex and variable low-temperature environments. Furthermore, conventional insulation structures suffer from high thermal inertia and poor temperature uniformity, failing to achieve efficient thermal management. Therefore, this invention proposes an intelligent protective insulation system integrating vortex thermal control and electromagnetic drive regulation. A vortex cooler achieves dynamic distribution of hot and cold flow, combined with an antifreeze circulation heating design to solve the problem of heat compensation in low-temperature environments; an electromagnetically driven regulating valve achieves precise control of the hot-end output, overcoming the limitations of slow response and low reliability of traditional mechanical regulation. This system aims to construct a multi-layered thermal protection system to ensure stable operation and accurate measurement of the vortex flowmeter in ultra-low temperature environments. Therefore, this invention was developed after in-depth research into the aforementioned problems. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0019] Example

[0020] like Figure 1-3 As shown, an ultra-low temperature vortex flow meter includes: a vortex flow valve body 1 and a protective heat insulation structure, wherein the protective heat insulation structure is installed on the vortex flow valve body 1. The protective heat insulation structure includes: a heat insulation box 2, a heat insulation inner box 3, antifreeze 4, multiple U-shaped heat dissipation pipes 5, multiple heat dissipation rings 6, multiple unidirectional drainage pipes 7, multiple heating components, a pair of air pumps 8, a pair of circulation diversion pipes 9, and a pair of temperature sensors.

[0021] Specifically, the inner casing 3 of the heat insulation kit is fitted onto the vortex flow valve body, the outer casing 2 of the heat insulation kit is fitted onto the outer side of the inner casing 3, the antifreeze 4 is placed inside the inner casing 3, multiple U-shaped heat dissipation pipes 5 are evenly inserted into the inner casing 3, multiple heat dissipation rings 6 are respectively installed on the outer side of the multiple U-shaped heat dissipation pipes 5, multiple one-way drainage pipes 7 are evenly inserted into the inner casing 2, multiple heating components are respectively connected to the multiple U-shaped heat dissipation pipes 5, and multiple heating components are evenly inserted into the inner casing 2, a pair of vacuum pumps 8 are installed inside the inner casing 2, a pair of circulation diversion pipes 9 are connected to the pair of vacuum pumps 8, and a pair of circulation diversion pipes 9 are connected to the multiple heating components, and a pair of temperature sensors are respectively installed inside the inner casing 2 and the inner casing 3.

[0022] It should be noted that, as described above, a pair of air pumps 8 operate to inflate the circulation diversion pipe 9, which in turn inflates multiple heating components. The heating components heat the gas, which is then directed to the inside of the U-shaped heat dissipation pipe 5. Multiple heat dissipation rings 6 on the U-shaped heat dissipation pipe 5 direct the heat from the air shaft to the antifreeze 4 in the inner box 3 of the insulation kit, thereby heating the antifreeze 4. The high-temperature antifreeze 4 then heats the eddy flow valve. A pair of temperature sensors control the temperature of the insulation kit box 2 and the inside of the inner box 3 of the insulation kit.

[0023] like Figure 1-3 As shown, the heating assembly includes: a T-shaped drain tube 10, a swirl starter 11, a cold end output tube 12, and a hot end output tube 13;

[0024] Specifically, the cold end output pipe 12 and the hot end output pipe 13 are respectively inserted into the T-shaped drain pipe 10. The cold end output pipe 12 is connected to the heat insulation box 2, the hot end output pipe 13 is connected to the U-shaped heat dissipation pipe 5, and the swivel starter 11 is installed on the inside of the T-shaped drain pipe 10.

[0025] It should be noted that, in the above, the T-shaped drain pipe 10 is filled with air through the circulation diversion pipe 9, and the vortex generator 11 is filled with air through the T-shaped drain pipe 10, thus forming a simple vortex cooler {high pressure compressed air enters the vortex tube nozzle through the tangential inlet, expands and accelerates, and then enters the vortex chamber at supersonic speed along the tangential direction to form a high-speed rotating vortex. The vortex moves spirally inside the tube, and a velocity gradient is generated between the inner and outer layers of gas due to the conservation of angular momentum. The inner layer, cold airflow, occurs as gas near the axial center converges towards the center due to centrifugal force, undergoing adiabatic expansion, resulting in a decrease in internal energy and a sharp drop in temperature (down to -46℃). The outer layer, hot airflow, occurs as gas near the tube wall, where viscous friction and a decrease in radial velocity cause some kinetic energy to be converted into heat, resulting in a significant increase in temperature (up to 127℃). Cooling mode: The cold airflow is guided through a central orifice plate and discharged from one end, directly used for localized cooling (e.g., tool cooling, electronic component heat dissipation). Heating mode: The hot airflow is controlled by a regulating valve, enabling precise heating of specific areas (e.g., assisting in heat sealing processes). This allows the gas discharged from the hot end output pipe 13 to be heated to about 100 degrees Celsius. The preheated gas is then guided through the U-shaped heat dissipation pipe 5 to the space between the heat insulation box 2 and the inner heat insulation box 3 for secondary circulation heating. By energizing the telescopic electromagnet on the inner side of the telescopic concave movable side, the telescopic magnet is magnetically repelled. The telescopic magnet drives the convex telescopic block on it, causing the convex telescopic slider 17 to stably extend and retract horizontally inside the concave telescopic slide. The convex telescopic slider 17 drives the rack on it, which in turn drives the gear 15 meshing with it to rotate. The gear 15 then drives the regulating valve 14 inside the hot end output pipe 13, thereby adjusting the heating effect.

[0026] As a preferred embodiment, furthermore, each of the multiple hot-end output pipes 13 is provided with a regulating valve 14.

[0027] As a preferred embodiment, furthermore, each of the plurality of regulating valves 14 is provided with a set of gears 15, and the inner side of the heat insulation box 2 is provided with a pair of telescopic concave slides 16, and the inner side of each pair of telescopic concave slides 16 is provided with a convex telescopic slider 17.

[0028] As a preferred embodiment, furthermore, each of the pair of convex telescopic sliders 17 is provided with a rack, and the pair of racks respectively mesh with the plurality of the sleeve gears 15.

[0029] As a preferred embodiment, a telescopic electromagnet is provided on the inner side of the pair of telescopic concave slides 16, and a telescopic magnet is provided on the pair of convex telescopic sliders 17.
