Description

Technical Field

[0001] This utility model relates to the field of hot water heating technology, specifically to an integrated temperature measuring sleeve. Background Technology

[0002] Hot water heating is a heating system that transfers heat through the circulation of hot water. Its core principle is to use hot water as a heat carrier to deliver heat energy to the user end to maintain indoor temperature. To ensure that the hot water temperature meets heating requirements, the temperature of the hot water in the heating pipes needs to be measured in real time, and then adjustments should be made promptly based on the measurement results.

[0003] For example, patent document CN219798571U, entitled "A Temperature Measuring Tool for Heating Pipelines," includes a metal thermometer body and a probe. The probe is fixedly connected to the bottom of the metal thermometer body, and a connecting cylinder is fixedly connected to the outer side of the bottom of the metal thermometer body. One end of the probe is provided with bristles, and the other end of the bristles is fixedly connected to a connecting plate. A rotating mechanism is fixedly connected to the top of the connecting plate and is located inside the connecting cylinder. A sealing mechanism is fixedly connected to the bottom of the connecting cylinder, and a pipe is spirally connected to the outer side of the connecting cylinder. The brush removes the unhardened scale adhering to the surface of the probe, which is then washed away with the hot water.

[0004] However, in the process of measuring hot water in the pipes, the metal thermometers mentioned above are prone to temperature measurement errors after long-term use. As a result, the real-time hot water temperature data collected in the pipes will be deviated. This deviation will further lead to errors in the temperature control process, which in turn will have an adverse effect on the heating effect. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an integrated temperature measuring sleeve to solve the technical problem mentioned in the background art where metal thermometers are prone to temperature measurement errors after long-term use, resulting in deviations in the real-time collected hot water temperature data inside the tube.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An integrated temperature measuring sleeve includes a base that is fixedly installed on a heating pipe and a sleeve that can be inserted into the base. One end of the sleeve is fixedly fitted with a thread, which is threaded to the base. A nut is fixedly installed on the top of the sleeve. The nut has two symmetrically arranged through holes, and a temperature transmitter and a thermocouple are respectively inserted into the two through holes.

[0007] Furthermore, the nut is provided with a clamping assembly for clamping the temperature transmitter and the thermocouple.

[0008] Furthermore, the clamping assembly includes two support plates fixedly disposed on the nut, a double-threaded rod rotatably disposed between the two support plates, and a guide rod fixedly disposed between the two support plates. The double-threaded rod is threadedly connected to two symmetrically arranged movable plates. The movable plates are slidably connected to the guide rod. The movable plates are provided with two symmetrically arranged sliding rods, and a clamping plate is fixedly disposed at one end of each sliding rod.

[0009] Furthermore, the slide rod is slidably connected to the corresponding movable plate, and a baffle is fixedly provided at the end of the slide rod away from the clamping plate. A spring is fixedly provided between the baffle and the corresponding movable plate.

[0010] Furthermore, a handle is rotatably provided on one side of one of the support plates, and the handle is coaxially and fixedly connected to the double-threaded rod.

[0011] Furthermore, a sealing ring is fixedly installed inside the base, and the sealing ring abuts against the thread.

[0012] The beneficial effects of this utility model are as follows: Since a nut is fixedly installed at the top of the sleeve, and the nut has two symmetrically arranged through holes, a temperature transmitter and a thermocouple are respectively inserted into the two through holes. Therefore, after long-term use, the temperature transmitter needs to be calibrated. The temperature measuring element of the temperature transmitter and the thermocouple are then inserted into the inside of the sleeve through the through holes to measure the temperature of the hot water in the heating pipe in real time. After obtaining the resistance value by measurement, it is analyzed with the help of a high-precision calibration instrument to obtain the specific temperature value. By comparing and analyzing the two values, errors can be accurately identified, ensuring the accuracy of the water temperature measurement in the pipe. This avoids the adverse effects on the heating effect caused by deviations in the hot water temperature data collected by the temperature transmitter in real time. Attached Figure Description

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0016] Example 1 like Figures 1-4 As shown, the integrated temperature measuring sleeve includes a base 2 fixedly installed on a heating pipe 1 and a sleeve 3 that can be inserted into the base 2. A perforation is formed in the wall of the heating pipe 1. The bottom end of the base 2 passes through the perforation of the heating pipe 1 and is sealed and fixedly connected to the heating pipe 1. The sleeve 3 is inserted into the base 2 and extends into the interior of the heating pipe 1. A thread 4 is fixedly fitted at the top of the sleeve 3, and the thread 4 is threadedly connected to the base 2. A nut 5 is fixedly installed at the top of the sleeve 3, and the nut 5 is fixedly connected to the thread 4, thus facilitating the installation and removal of the sleeve 3. A raised edge is provided circumferentially at the bottom of the base 2, and a sealing ring 8 is fixedly installed at the top of the raised edge. The sealing ring 8 abuts against the thread 4, facilitating the sealing of the heating pipe 1 and preventing water from overflowing from the base 2.

[0017] To address the issue of measurement errors easily occurring in the temperature transmitter 6 over time, leading to malfunctions in temperature control and adversely affecting heating performance, and to facilitate the verification, comparison, and correction of temperature error values ​​measured by the temperature transmitter 6, two symmetrically arranged through holes 51 are provided on the top of the nut 5. These two through holes 51 communicate with the interior of the sleeve 3. A temperature transmitter 6 and a thermocouple 7 are respectively inserted into each of the two through holes 51. The temperature sensing element of the temperature transmitter 6 and the thermocouple 7 extend into the interior of the sleeve 3 to facilitate real-time temperature measurement of the hot water in the heating pipe 1. After measuring the resistance values ​​obtained by the temperature transmitter 6 and the thermocouple 7, a high-precision calibration instrument is used to analyze and derive the specific temperature value. By comparing and analyzing these two values, errors can be accurately identified, ensuring the accuracy of the temperature transmitter 6's measurement of the water temperature in the heating pipe 1. In addition, this method does not require changing the installation method of the original temperature transmitter 6, which not only ensures the original performance, but is also more efficient than the traditional surface temperature measurement method, and is easy to operate and accurate.

[0018] Example 2 like Figure 2 and Figure 4As shown, the nut 5 is equipped with a clamping assembly for clamping the temperature transmitter 6 and the thermocouple 7. The clamping assembly includes two support plates 9 fixedly mounted on the top of the nut 5, a double-threaded rod 10 rotatably mounted between the two support plates 9, and a guide rod 11 fixedly mounted between the two support plates 9. The two support plates 9 are symmetrically arranged about the center line of the nut 5. The two ends of the double-threaded rod 10 rotatably pass through the corresponding support plates 9. The double-threaded rod 10 is threadedly connected to two symmetrically arranged movable plates 12, with the threads on both sides of the double-threaded rod 10 having opposite directions. The movable plates 12 are slidably fitted with the guide rod 11. A handle 13 is rotatably mounted on one side of one of the support plates 9, and the handle 13 is coaxially fixedly connected to the double-threaded rod 10. Two symmetrically arranged sliding rods 14 are slidably mounted on the movable plate 12, and a clamping plate 15 is fixedly mounted on one end of each sliding rod 14. Multiple clamping plates 15 are respectively adapted to the outer periphery of the temperature sensing element of the temperature transmitter 6 and the thermocouple 7.

[0019] After inserting the temperature sensing element and thermocouple 7 of the temperature transmitter 6 into the corresponding through holes 51, the handle 13 is turned. The handle 13 drives the double-ended threaded rod 10 to rotate. The rotation of the double-ended threaded rod 10 drives the two moving plates 12 to move towards each other. The moving plates 12 drive the clamping plate 15 through the slide rod 14 to clamp the temperature sensing element and thermocouple 7 of the temperature transmitter 6, preventing the temperature transmitter 6 and thermocouple 7 from becoming loose when measuring the water temperature, or preventing the staff from accidentally touching the temperature transmitter 6 and thermocouple 7, which would result in the temperature transmitter 6 and thermocouple 7 not being properly inserted, affecting the accuracy of the water temperature measurement.

[0020] To prevent the clamping plate 15 from clamping the temperature sensing element and thermocouple 7 of the temperature transmitter 6 too tightly and causing damage, a sliding rod 14 is slidably mounted on the corresponding moving plate 12. A baffle 16 is fixedly installed at the end of the sliding rod 14 away from the clamping plate 15. A spring 17 is fixedly installed between the baffle 16 and the corresponding moving plate 12, and the spring 17 is sleeved on the outer circumference of the sliding rod 14. Therefore, when the clamping plate 15 comes into contact with the temperature sensing element and thermocouple 7 of the temperature transmitter 6, if the handle 13 is continued to be turned to rotate the double-ended threaded rod 10, thereby driving the two moving plates 12 to move further, the clamping plate 15 will be obstructed, causing the corresponding sliding rod 14 to move synchronously. At this time, the sliding rod 14 stretches the spring 17 through the baffle 16, thus preventing the clamping plate 15 from damaging the temperature sensing element and thermocouple 7 of the temperature transmitter 6 due to excessive clamping.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
