Abstract
Description
Technical Field
[0001] This utility model relates to the field of transmitter technology, specifically a high-precision pressure level transmitter with temperature regulation. Background Technology
[0002] A level transmitter is an industrial measuring device used to detect and transmit information about the liquid level in a tank or container. It converts the measured liquid level into a continuous signal for automated control systems to receive and process, enabling real-time monitoring, automatic replenishment, or alarm control to prevent risks such as overflow and dry running.
[0003] In existing technologies, during industrial production, it is necessary to use transmitters to monitor pipeline flow and liquid level parameters in real time to ensure production safety. By monitoring flow and liquid level in real time, the system can detect abnormal fluctuations and trigger early warnings in a timely manner. At the same time, based on the monitoring data, production personnel can dynamically adjust equipment operating parameters to achieve precise material delivery and proportioning, thus avoiding waste.
[0004] However, when used in different seasons, due to temperature differences, when liquid flows in the pipeline, such as in winter, the smaller diameter of the pipeline slows down the flow rate of the liquid, which may cause the liquid inside to gradually solidify. After solidification, the volume of the liquid expands, which may block the flow section of the pipeline. If the solidification range expands or the pipeline freezes completely, the pressure inside the pipeline will increase sharply, exceeding the pipeline's tolerance limit and causing the pipeline to rupture. To address this, we propose a high-precision pressure level transmitter with temperature regulation. Utility Model Content
[0005] One of the technical problems this application aims to solve is: to regulate the temperature of the liquid in the transmitter channel so that it can be used according to different seasons.
[0006] To address the aforementioned technical problems, this application provides a high-precision pressure level transmitter with temperature regulation, comprising an adjustment mechanism. A limit mechanism is provided on the bottom side of the adjustment mechanism. The adjustment mechanism includes a connecting pipe, an internal baffle, and a fixed connection between the inside of the connecting pipe and one end of the baffle. A semi-circular plate is provided inside the connecting pipe, and its arc surface is fixedly connected to the inside of the semi-circular plate. A second semi-circular plate is provided on one side of the first semi-circular plate, and one side of the first semi-circular plate rotatably contacts one side of the second semi-circular plate. An outer ring is provided on the arc surface of the second semi-circular plate, and its arc surface is fixedly connected to the inner side of the outer ring. A solution chamber is provided at one end of the connecting pipe, and the end of the connecting pipe is fixedly connected to one end of the solution chamber.
[0007] In some embodiments, the limiting mechanism includes a cavity, an inner surface of which is provided with a spring piece, the inner surface of which is fixedly connected to the bottom end of the spring piece, and a limiting plate is provided at the top end of the spring piece, the top end of which is fixedly connected to the bottom end of the limiting plate.
[0008] In some embodiments, the top protrusion of the limiting plate is rotatably engaged with the recess of the outer ring, and the top of the cavity is fixedly connected to the bottom side of the connecting tube.
[0009] In some embodiments, the outer side of the outer ring is rotatably connected to the inner wall of the connecting tube, and a first wire is provided on the inner wall of the connecting tube, and the inner wall of the connecting tube is fixedly connected to the outer side of the first wire.
[0010] In some embodiments, a heating element is provided at one end of the first wire, and one end of the first wire is fixedly connected to one end of the heating element. The outer side of the heating element is fixedly connected to the inner wall of the baffle.
[0011] In some embodiments, a guide plate is provided at the end of the wire away from the heating element, and the end of the wire away from the heating element is fixedly connected to one side of the guide plate. A plug is provided on the inner side of the guide plate, and the inner side of the guide plate is fixedly connected to one end of the plug.
[0012] In some embodiments, the inner wall of the solution cavity is provided with a jacket, and the upper and lower sides of the solution cavity are respectively provided with an inlet and an outlet, and the upper and lower sides of the solution cavity are respectively fixedly connected to one end of the inlet and the outlet.
[0013] In some embodiments, a liquid pipe is provided at one end of the solution chamber, and the one end of the solution chamber is fixedly connected to the one end of the liquid pipe. A transmitter body is provided at the end of the liquid pipe away from the solution chamber, and the one end of the solution chamber is fixedly connected to the connection end of the transmitter body.
[0014] This utility model has at least the following beneficial effects:
[0015] 1. The liquid flows into the connecting pipe. Since there are multiple baffles in the connecting pipe, the baffles are installed in a staggered manner, and each baffle has a heating element. Therefore, with the staggered installation of the baffles and the temperature of the heating element being raised, the liquid needs to change its flow direction multiple times after contacting the baffle. At the same time, it ensures that the liquid is heated evenly in winter and effectively prevents the liquid from solidifying. A jacket is opened on the inner wall of the solution chamber. By pouring coolant into the jacket, the liquid can absorb heat from the liquid when it passes through the solution chamber in summer. The temperature of the liquid can be adjusted according to different seasons, thereby increasing the flexibility of the transmitter.
[0016] 2. By rotating the outer ring, the second semicircular plate is no longer in a circular alignment with the first semicircular plate, thereby opening the liquid channel. As the rotation angle of the outer ring increases, the liquid channel further enlarges. This effectively controls the liquid flow rate, regulates the liquid flow rate, balances system pressure, and adapts to measurement needs under different working conditions.

[0026] Example 1: Please refer to Figures 1-6This utility model provides a technical solution: a high-precision pressure level transmitter with temperature regulation, including an adjustment mechanism 1, a limit mechanism 2 provided on the bottom side of the adjustment mechanism 1, the adjustment mechanism 1 including a connecting pipe 14, a baffle 18 provided inside the connecting pipe 14, the inside of the connecting pipe 14 being fixedly connected to one end of the baffle 18, a semi-circular plate 110 provided inside the connecting pipe 14, the inside of the connecting pipe 14 being fixedly connected to the arc surface of the semi-circular plate 110, and a... A semicircular plate 112 is provided. One side of a semicircular plate 110 is rotatably in contact with one side of a semicircular plate 112. An outer ring 111 is provided on the arc surface of the semicircular plate 112. The arc surface of the semicircular plate is fixedly connected to the inner side of the outer ring 111. A solution chamber 13 is provided at one end of a connecting pipe 14. One end of the connecting pipe 14 is fixedly connected to one end of the solution chamber 13. The outer side of the outer ring 111 is rotatably connected to the inner wall of the connecting pipe 14. A wire 16 is provided on the inner wall of the connecting pipe 14. The inner wall of the connecting pipe 14 is connected to the wire. A heating element 15 is fixedly connected to the outer side of a wire 16. One end of the wire 16 is fixedly connected to one end of the heating element 15. The outer side of the heating element 15 is fixedly connected to the inner wall of the baffle 18. A flow guide plate 17 is provided at the end of the wire 16 away from the heating element 15. This end is fixedly connected to one side of the flow guide plate 17. A plug 19 is provided on the inner side of the flow guide plate 17. One end of the plug 19 is fixedly connected to the inner side of the flow guide plate 17. The solution... The inner wall of cavity 13 is provided with a jacket 113. The upper and lower sides of the solution cavity 13 are respectively provided with an inlet 114 and an outlet 115. The upper and lower sides of the solution cavity 13 are fixedly connected to one end of the inlet 114 and the outlet 115, respectively. One end of the solution cavity 13 is provided with a liquid pipe 12, and one end of the solution cavity 13 is fixedly connected to one end of the liquid pipe 12. The end of the liquid pipe 12 away from the solution cavity 13 is provided with a transmitter body 11, and one end of the solution cavity 13 is fixedly connected to the connection end of the transmitter body 11.
[0027] In use, this type of high-precision pressure-level transmitter with temperature regulation operates as follows: First, the transmitter body 11 is equipped with a flange, which connects to the liquid channel. Naturally, a liquid pipe 12 is fixedly installed at the center of the flange and passes through it. One end of the liquid pipe 12 connects to a solution chamber 13, and one end of the solution chamber 13 is fixedly connected to a connecting pipe 14. The interior of the connecting pipe 14 is square-shaped. Then, multiple baffles 18 are installed inside the connecting pipe 14 in a staggered manner. Each baffle 18 contains a heating element 15. To prevent the liquid from freezing during flow, especially in winter, a connection is made between the connecting end and the liquid inlet, allowing the liquid to flow into the connecting pipe 14. Inside, a guide plate 17 is designed on the bottom side of the connecting pipe 14. A plug 19 is fixedly connected to the middle of the inner side of the guide plate 17. By connecting the plug 19 to the power supply, the current is introduced into the wire 16 through the guide plate 17, thereby heating the heating element 15 in the baffle 18. In this way, when the liquid flows, with the baffle 18 installed in a staggered manner, the liquid needs to change its flow direction multiple times to fully contact the baffle 18. At the same time, it ensures that the liquid is heated evenly and effectively prevents the liquid from solidifying. Finally, it enters the liquid pipe 12 through the solution chamber 13, and then the liquid pipe 12 guides the liquid into the transmitter body 11, ensuring the accuracy of the pressure and level transmitter measurement. The guide plate 17 used is made of metal conductive material and has an insulating coating on the outside.
[0028] A jacket 113 is provided on the inner wall of the solution chamber 13, and the liquid inlet 114 is provided on the top side of the solution chamber 13. Therefore, by pouring coolant into the jacket 113, when the liquid passes through the solution chamber 13 in summer, the coolant in the jacket 113 absorbs the heat of the liquid and lowers the liquid temperature, avoiding changes in the liquid properties or affecting the measurement accuracy of the pressure and level transmitter due to high temperature. Therefore, the temperature of the liquid can be adjusted according to different seasons, thereby increasing the flexibility of the transmitter.
[0029] A semicircular plate 110 is provided inside the connecting pipe 14. A semicircular plate 2 is provided on one side of the semicircular plate 110, and an outer ring 111 is fixed on the outer side of the arc surface of the semicircular plate 2. By rotating the outer ring 111, the semicircular plate 2 112 is no longer in a circular alignment with the semicircular plate 110, thereby opening the liquid channel. As the rotation angle of the outer ring 111 increases, the liquid channel is further enlarged. This can effectively control the liquid flow rate, regulate the liquid flow, balance the system pressure, and adapt to the measurement needs of different working conditions. For example, the flow rate can be reduced to prolong the heat exchange time when heating in winter, and the flow rate can be increased to improve the heat dissipation efficiency when cooling in summer, while avoiding measurement errors caused by abnormal flow rate.
[0030] Example 2: Please refer to Figures 1-4The limiting mechanism 2 includes a cavity 21, and a spring piece 22 is provided on the inner surface of the cavity 21. The inner surface of the cavity 21 is fixedly connected to the bottom end of the spring piece 22. A limiting plate 23 is provided on the top end of the spring piece 22. The top end of the spring piece 22 is fixedly connected to the bottom end of the limiting plate 23. The protrusion at the top end of the limiting plate 23 is rotatably engaged with the recess of the outer ring 111. The top end of the cavity 21 is fixedly connected to the bottom side of the connecting pipe 14.
[0031] A recess is provided along the circumference of the outer ring 111, and a cavity 21 is fixed on the bottom side of the connecting pipe 14. A spring piece 22 is connected to the inner surface of the cavity 21, and a limiting plate 23 is fixed to the top of the spring piece 22. The protrusion of the limiting plate 23 fits into the recess. In this way, when the outer ring 111 rotates, the limiting plate 23 will move down under the action of the spring piece 22 when the recess aligns with the protrusion. Then, when the recess aligns with the protrusion, the spring piece 22 uses its retractability to push up the limiting plate 23, and rotates and engages with the outer ring 111 in an undulating manner. This allows the outer ring 111 to remain stationary in its original position after rotation, achieving precise positioning and locking of the flow rate adjustment level, preventing the outer ring 111 from rotating on its own due to external forces such as vibration and liquid impact, and ensuring the stability of liquid flow rate control.
[0032] Please see Figures 1-6 The liquid is connected to the liquid inlet via a connecting end. The liquid flows into the connecting pipe 14. A guide plate 17 is designed on the bottom side of the connecting pipe 14, and a plug 19 is fixedly connected to the inner middle of the guide plate 17. The plug 19 is then connected to a power source, allowing current to flow through the guide plate 17 to the conductor 16, thereby heating the heating element 15 in the baffle 18. Because the baffle 18 is installed in a staggered manner, the liquid needs to change its flow direction multiple times to ensure full contact with the baffle 18, ensuring uniform heating and effectively preventing solidification. Finally, the liquid enters the liquid pipe 12 through the solution chamber 13, and then flows through the liquid pipe 1... 2. The liquid is introduced into the transmitter body 11. A jacket 113 is provided on the inner wall of the solution chamber 13, and the liquid inlet 114 is provided on the top side of the solution chamber 13. Therefore, by pouring coolant into the jacket 113, when the liquid passes through the solution chamber 13 in summer, the coolant in the jacket 113 absorbs the heat of the liquid and lowers the liquid temperature. By rotating the outer ring 111, the semicircular plate 112 is no longer in a circular alignment with the semicircular plate 110, thereby opening the liquid channel. As the rotation angle of the outer ring 111 increases, the liquid channel further increases, which can effectively control the liquid flow rate.
[0033] As the outer ring 111 rotates, a cavity 21 is installed on the bottom side of the connecting pipe 14. A spring piece 22 is connected to the inner surface of the cavity 21, and a limiting plate 23 is fixed at the top of the spring piece 22. As the outer ring 111 rotates, the limiting plate 23 will move down when the concave part aligns with the convex part under the action of the spring piece 22. Then, when the concave part aligns with the convex part, the spring piece 22 uses its retractability to push up the limiting plate 23, and rotates and engages with the outer ring 111 in an undulating manner. This allows the outer ring 111 to remain stationary in its original position after rotation.
