[0002] A flow meter is a device used to measure the rate or total amount of fluid flowing through a pipe or tube; they are important in many industrial and commercial applications, from monitoring processes to ensuring systems are operating correctly.

[0003] Flow meters are usually used to measure media (liquid or steam). In cold climates, the application temperature of the flow meter will decrease, affecting the measurement performance of the flow meter. In the prior art, an antifreeze box is added to the outside of the flow meter to achieve the effect of insulation. However, for colder working conditions, there is still a hidden danger of freezing, which affects the normal application of the flow meter. When the medium transported in the flange pipe is warm, the temperature of the medium cannot be utilized. When maintaining the flow meter, the antifreeze box is not convenient to disassemble, resulting in a long maintenance time. Therefore, in order to solve the above problems, an adaptive antifreeze flow meter is proposed. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1-2 , the utility model provides an embodiment: an adaptive antifreeze flowmeter, comprising a flange pipe 1, a flow meter 4 is penetrated through the outer wall of the flange pipe 1, an output pipe 2 is fixedly connected to the outer wall of the flange pipe 1, an input pipe 5 is fixedly connected to one end of the output pipe 2, a solenoid valve 1 3 is arranged inside the output pipe 2, a solenoid valve 2 6 is arranged inside the input pipe 5, a first antifreeze box 7 and a second antifreeze box 8 are arranged on the outer wall of the flowmeter 4, a temperature sensor 9 is fixedly connected inside the first antifreeze box 7, and a dehumidification component is arranged inside the first antifreeze box 7 and the second antifreeze box 8;

[0030] Specifically, when heat preservation is required, the solenoid valve 1 3 and the solenoid valve 2 6 at the output pipe 2 and the input pipe 5 are opened to allow the medium to flow through the output pipe 2 and the input pipe 5, and the first antifreeze box 7 and the second antifreeze box 8 are heated. When measuring the medium flow in the flange pipe 1, the detection end of the flow meter 4 is inserted into the flange pipe 1 to accurately measure the medium. In this process, the first antifreeze box 7 and the second antifreeze box 8 play a key role. They jointly provide heat preservation and antifreeze protection for the output pipe 2, the flow meter 4 and the input pipe 5 to ensure that the measurement process is not affected by the ambient temperature. However, we must pay attention to an important issue. Due to the excessively high temperature of the medium, the first antifreeze box 7 and the second antifreeze box 8 may be The temperature inside the freezer 8 rises. If the temperature is too high, the flow meter 4 may be damaged. In order to prevent this from happening, we install a temperature sensor 9 inside the first antifreeze box 7. The temperature sensor 9 will monitor the internal temperature in real time. Once it finds that the temperature is too high, it will take immediate action. Specifically, when the temperature sensor 9 detects that the internal temperature is too high, it will close the solenoid valve 1 3 and the solenoid valve 2 6 to stop the passage of the medium. This can effectively prevent the high temperature from damaging the flow meter 4. When the temperature sensor 9 detects that the internal temperature has dropped to a safe range, it will reopen the solenoid valve 1 3 and the solenoid valve 2 6 to allow the medium to continue to pass so that flow measurement can be performed.

[0031] Reference Figure 2 The dehumidification component includes a dehumidifier 10 and a moisture-proof layer 11. The inner walls of the first antifreeze box 7 and the second antifreeze box 8 are fixedly connected with the moisture-proof layer 11, and one side of the dehumidifier 10 is fixedly connected to the inside of the second antifreeze box 8;

[0032] Specifically, since the external air is too humid, the temperature inside the first antifreeze box 7 and the second antifreeze box 8 is relatively high, which will cause condensation water to be generated inside them. In order to avoid this situation, a moisture-proof layer 11 is arranged between the first antifreeze box 7 and the second antifreeze box 8. This moisture-proof layer can effectively reduce the adhesion of condensation water, thereby protecting the equipment from the influence of moisture. In order to further reduce the generation of condensation water, a dehumidifier 10 is also used inside the second antifreeze box 8. This dehumidifier 10 can effectively reduce the air humidity inside the first antifreeze box 7 and the second antifreeze box 8, thereby further reducing the possibility of condensation water generation inside. In general, by using the moisture-proof layer 11 and the dehumidifier 10, the first antifreeze box 7 and the second antifreeze box 8 can be effectively protected from the influence of moisture, thereby ensuring the normal operation of the equipment. This design is very important for equipment used in a humid environment, and it can effectively extend the service life of the equipment.

[0033] Reference Figure 3, both sides of the outer wall of the second antifreeze box 8 are fixedly connected with connecting blocks 12, and a card slot 13 is opened inside the connecting block 12, and both sides of the first antifreeze box 7 are fixedly connected with mounting blocks 14, and the mounting blocks 14 are fixedly connected with limiting columns 15 inside. The outer wall of the limiting column 15 is symmetrically arranged and slidably connected with a support plate 16, and the top of the support plate 16 is rotatably connected with a connecting rod 17, and one end of the connecting rod 17 is rotatably connected with a card block 18, and the top of the card block 18 is rotatably connected with a limiting rod 19, and the outer wall of the card block 18 is embedded in the card slot 13, and the outer wall of the limiting column 15 is provided with a spring 20, and both ends of the spring 20 are fixedly connected between the support plates 16;

[0034] Specifically, the first antifreeze box 7 and the second antifreeze box 8 are tightly connected together through a series of mechanical structures to ensure their sealing and stability. However, sometimes we need to open the first antifreeze box 7 and the second antifreeze box 8 to perform some operations, such as checking the operation of the equipment or performing maintenance. To open the first antifreeze box 7 and the second antifreeze box 8, the user only needs to gently pinch the support plates 16 on both sides of the first antifreeze box 7 with both hands. This action will drive a series of connecting rods 17 and card blocks 18 through the support plates 16 to separate the card blocks 18 from the card slots 13. At this time, the connection between the first antifreeze box 7 and the second antifreeze box 8 is unlocked, and the user can easily separate the two parts. In addition, the process of reinstalling the first antifreeze box 7 and the second antifreeze box 8 is also very simple. The user only needs to buckle the two parts together again, so that the card block 18 is smoothly inserted into the card slot 13 in the connecting block 12, and the support plate 16 is unfolded and locked by the tension of the spring 20. In this way, the antifreeze box has restored its sealing and stability and can continue to provide good protection for the equipment.

[0035] Working principle: The temperature sensor 9, flow meter 4, solenoid valve 1 3 and solenoid valve 2 6 are electrically connected to an external integrator through wires, and the integrator displays flow information and coordinates working conditions;

[0036] When using the adaptive antifreeze flowmeter, the medium with temperature (liquid or steam) will flow through the flange pipe 1, and part of the medium will be led out through the output pipe 2 and returned to the inside of the flange pipe 1 through the input pipe 5. The temperature in the medium is transferred to the first antifreeze box 7 and the second antifreeze box 8 to insulate the flow meter 4. The temperature sensor 9 measures the temperature inside the first antifreeze box 7. When the temperature is high, the solenoid valve 1 3 and the solenoid valve 2 6 will be gradually closed to reduce the amount of medium passing through until it is closed. When the temperature sensor 9 measures the internal temperature drop, the solenoid valve 1 3 and the solenoid valve 2 6 will be reopened to measure the flow of the medium. Since the external air is too low, the internal temperature of the first antifreeze box 7 and the second antifreeze box 8 is high, which will produce condensed water inside. Therefore, the first antifreeze box 7 and the second antifreeze box 8 by a moisture-proof layer 11 to reduce the adhesion of condensed water, and the dehumidifier 10 is used inside the second antifreeze box 8 to reduce the air humidity inside the first antifreeze box 7 and the second antifreeze box 8, thereby reducing the effect of condensed water generated inside. When the first antifreeze box 7 and the second antifreeze box 8 need to be opened, it is only necessary to pinch the support plates 16 on both sides of the first antifreeze box 7, and drive the connecting rod 17 through the support plate 16 to push the card block 18 to support it, and at the same time, the card block 18 is closed and separated from the card slot 13, and then the first antifreeze box 7 and the second antifreeze box 8 are separated. When reinstalling the first antifreeze box 7 and the second antifreeze box 8, it is only necessary to buckle them again, so that the card block 18 is inserted into the connecting block 12 and locked through the card slot 13, and the support plate 16 is expanded and engaged through the card block 18 through the tension of the spring 20.
