Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe technology, specifically to a stainless steel pipe with temperature monitoring function. Background Technology

[0002] In the fields of energy, power, and chemical industry, stainless steel tubes for high-pressure boilers are subjected to high temperature (500-900℃), high pressure (10-30MPa) and complex media corrosion environment for a long time. The distribution of their thermal stress directly affects the safe operation of the equipment.

[0003] Traditional stainless steel pipe temperature monitoring relies on external contact sensors (such as thermocouples) or offline detection, which makes it difficult to obtain real-time temperature field and thermal stress data of the inner wall of the pipe. External sensors have defects such as low installation accuracy and large response delay, and cannot accurately reflect the local overheating of the inner wall. Utility Model Content

[0025] 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.

[0026] Please see Figures 1-4 This utility model discloses a stainless steel pipe with temperature monitoring function, comprising a stainless steel pipe body 1, an alarm 6 provided on the outer wall of the stainless steel pipe body 1, a slot 8 provided on the stainless steel pipe body 1, an annular seat 7 fixed on the outer wall of the stainless steel pipe body 1 at the top of the slot 8, a support rod 10 provided in the slot 8, a temperature sensor 9 inserted into the stainless steel pipe body 1 at the bottom end of the support rod 10, a cylindrical block 11 provided at the top end of the support rod 10, the cylindrical block 11 passing through the annular seat 7 and threadedly connected to the annular seat 7, a circular baffle 12 provided at the top end of the cylindrical block 11, and the lower end of the circular baffle 12 tightly fitting the upper end of the annular seat 7.

[0027] Two annular blocks 2 are provided in symmetrical slots 8 on the outer wall of the stainless steel pipe body 1. An annular groove 3 is provided between the two annular blocks 2. Two arc-shaped clamping plates 4 are symmetrically arranged in the annular groove 3. The two arc-shaped clamping plates 4 are fixed inside the annular groove 3 by screws. A protective cylinder 5 is provided in the middle part of the arc-shaped clamping plate 4. The alarm 6 is fixed at the upper end of the protective cylinder 5, and the temperature sensor 9 is connected to the alarm 6 by an electrical signal.

[0028] The temperature sensor 9 is a platinum thin-film strain sensor.

[0029] The circular baffle 12 and the actuating block 13 are both located inside the protective cylinder 5.

[0030] When the stainless steel pipe body 1 operates in a high-temperature environment, the temperature sensor 9 inserted inside the pipe senses the temperature change of the inner wall in real time and transmits the signal to the alarm 6 on the outer wall. The temperature sensor 9 is fixed to the cylindrical block 11 by the support rod 10. Rotating the top actuating block 13 allows the cylindrical block 11 to be threadedly connected to the annular seat 7, tightly pressing the circular baffle 12 onto the annular seat 7, ensuring stable installation and reliable sealing of the sensor. In the annular groove 3 between the two annular blocks 2, the upper and lower symmetrical arc-shaped clamping plates 4 are fixed by screws, forming a support for the protective cylinder 5. The protective cylinder 5 encloses the circular baffle 12 and the actuating block 13, preventing external impact and corrosion. When the temperature exceeds the preset threshold, the alarm 6 automatically triggers, reminding the operator to handle the situation promptly.

[0031] During assembly, simply insert the temperature sensor 9 along with the support rod 10 into the empty slot 8, rotate the actuating block 13 to screw the cylindrical block 11 into the annular seat 7, until the sealing ring at the lower end of the circular baffle 12 is tightly fitted with the annular seat 7, and the installation is complete. This design facilitates the disassembly and maintenance of the sensor.

[0032] The circular baffle 12, the cylindrical block 11, and the support rod 10 are an integrated structure.

[0033] The integrated structure of the circular baffle 12, the cylindrical block 11 and the support rod 10, combined with the threaded connection of the annular seat 7, makes the sensor installation and operation simple.

[0034] The lower end of the circular baffle 12 is provided with a sealing ring that contacts the annular seat 7.

[0035] The sealing ring at the lower end of the circular baffle 12 ensures the sealing of the slot 8, preventing media leakage or intrusion of external impurities.

[0036] The upper end of the circular baffle 12 is provided with a toggle block 13.

[0037] The toggle block 13 is designed for easy manual rotation, allowing for assembly and disassembly without additional tools, thus improving maintenance efficiency.

[0038] The outer wall of the stainless steel pipe body 1 is provided with a wear-resistant protective coating, and the inner wall of the stainless steel pipe body 1 is provided with an anti-corrosion coating.

[0039] The wear-resistant protective coating on the outer wall of the stainless steel pipe body 1 and the anti-corrosion coating on the inner wall enhance the pipe's resistance to external wear and internal media corrosion, respectively, extending its service life. The arc-shaped clamping plate 4 in the annular groove 3 fixes the protective cylinder 5, enclosing components such as the alarm 6 and the toggle block 13, which can resist external mechanical impact and corrosive environment, ensuring the long-term stable operation of the monitoring system.

[0040] In summary, this stainless steel pipe, through its reasonable structural design and functional integration, achieves real-time monitoring and early warning of the inner wall temperature. It also features convenient installation, strong protection, and high reliability, making it suitable for high-temperature and high-pressure scenarios such as high-pressure boilers and chemical pipelines, and providing effective technical support for the safe operation of industrial equipment.
