Abstract
Description
Technical Field
[0001] The invention relates to the technical field of thermal control instrument installation, in particular to a thermal control instrument installation structure. Background Art
[0002] Thermal control instruments are precision devices specially designed to measure and control the temperature in industrial processes. Their working principle is based on different temperature sensing technologies, such as resistance temperature detectors (RTDs), thermocouples, etc. These sensors can convert temperature changes into electrical signals, which are then processed and displayed by the electronic circuits inside the instrument. As an indispensable temperature monitoring tool in the industrial field, thermal control instruments are widely used for temperature detection in various pipeline systems. This type of instrument is usually fixed to the pipeline by flange connection, and the flange structure ensures that it is in close contact with the part to be measured to accurately obtain temperature data.
[0003] However, the traditional flange connection method limits the installation flexibility of thermal control instruments, especially when facing inclined pipeline detection points. When the pipeline is not installed horizontally or vertically but at a certain tilt angle, the thermal control instrument using standard flange connection will also present a corresponding tilt posture. This physical tilt not only increases the difficulty for operators to read instrument data, but may also affect the accuracy of measurement results. In addition, due to the lack of an effective angle adjustment mechanism, the application of traditional thermal control instruments in special locations is greatly limited, especially for situations where side installation is required, and existing designs often fail to meet actual needs.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.
[0033] Example 1
[0034] Reference Figure 1 , which is the first embodiment of the present invention, and provides a thermal control instrument installation structure, including a unit to be detected 100, including a detection tube 101, and a detection end 102 arranged on one side of the detection tube 101;
[0035] The mounting unit 200 includes a flange ring 201 disposed on the detection end 102, and a limit plate 202 clamped and disposed on the inner side of the flange ring 201;
[0036] The thermal control instrument 300 is inside the axis limiting plate 202 of the thermal control instrument 300 .
[0037] It should be noted that, in this embodiment, the unit to be detected 100 is a conveying pipeline, wherein the detection tube 101 is the detected section, and a port protrudes outward at one end of the detection tube 101, namely the detection end 102, and the detection end 102 can be connected to the thermal control instrument 300 through a flange connection. The installation unit 200 can fix the thermal control instrument 300 on the detection end 102. The thermal control instrument 300 is a thermistor thermometer, which has a semiconductor material with a negative temperature coefficient in its tube, and its resistance value decreases rapidly as the temperature increases. By measuring the change in resistance value, the temperature can be determined.
[0038] Preferably, the installation unit 200 in this example can make the thermal control instrument 300 flange-connected to the detection end 102, and can also realize the axis limit at the center of the installation unit 200 to achieve fixed-point deflection. Among them, the flange ring 201 is fixed to the flange interface of the detection end 102 by bolts. Ensure the sealing and pressure resistance of the inner side of the detection end 102 to prevent medium leakage or external contaminants from entering. The limit plate 202 is tightly limited at the interface of the detection end 102 by the clamping action of the flange ring 201.
[0039] Preferably, the limit plate 202 in this embodiment has the function of limiting the axis of the thermal control instrument 300, which can limit the thermal control instrument 300 at the center of the limit plate 202, allowing it to deflect and adapt to the side-mounted detection tube 101, making it easier for staff to read the numbers.
[0040] Preferably, the limit plate 202 can be of axial hinged type. A hinge hole is provided at the center of the limit plate 202, and the diameter of the hinge hole is slightly larger than the diameter of the hinge column end of the metal rod peripheral of the thermal control instrument 300 to ensure that the hinge column end can be smoothly inserted into the hinge hole. A hinge column end is provided at the end of the metal rod of the thermal control instrument 300, and the shape and size of the hinge column end match the hinge hole on the limit plate 202 to ensure a stable connection between the two. When the thermal control instrument 300 is fixed to the detection end 102 by the flange ring 201, the hinge column end at the end of the metal rod is inserted into the hinge hole of the limit plate 202, so that the thermal control instrument 300 can achieve fixed-point deflection at the center of the limit plate 202.
[0041] Preferably, the limit plate 202 is a spherical hinged type. A spherical groove is provided on the limit plate 202, and the shape and size of the groove match the ball head at the end of the metal rod of the thermal control instrument 300. A ball head is provided at the end of the metal rod of the thermal control instrument 300, and the ball head can rotate freely in the spherical groove of the limit plate 202 to ensure the deflection of the thermal control instrument 300 in multiple directions. When the thermal control instrument 300 is fixed to the detection end 102 through the flange ring 201, the ball head at the end of the metal rod is embedded in the spherical groove of the limit plate 202, so that the thermal control instrument 300 can achieve multi-directional deflection at the center of the limit plate 202.
[0042] Preferably, the limit plate 202 is a magnetic limit plate. The limit plate 202 is embedded with a plurality of small magnets, which are evenly distributed along the circumference of the limit plate 202. The number and position of the magnets can be adjusted according to actual needs to ensure sufficient adsorption force. The end of the metal rod of the thermal control instrument 300 is made of magnetic material, such as iron or nickel alloy. These materials can be adsorbed by the magnet on the limit plate 202 to ensure the stable installation of the thermal control instrument 300. The limit plate 202 is fixed to the detection end 102 through the flange ring 201 to ensure that the interface between the limit plate 202 and the detection end 102 fits tightly. Align the end of the metal rod of the thermal control instrument 300 with the magnet area on the limit plate 202, and slowly approach the limit plate 202 so that the magnetic material is adsorbed by the magnet. By manually rotating the metal rod of the thermal control instrument 300, the angle of the thermal control instrument 300 can be freely adjusted on the limit plate 202.
[0043] In summary, the thermal control instrument installation structure provided in this embodiment can not only ensure the stable installation of the thermal control instrument 300 on the detection end 102, but also realize the axis limit and fixed-point deflection of the thermal control instrument 300 through the arrangement of the flange ring 201 and the limit plate 202. This design greatly improves the applicability and reliability of the thermal control instrument 300 in different installation positions and angles, and provides a more flexible and efficient solution for temperature monitoring in industrial production.
[0044] Example 2
[0045] Reference Figure 1 to Figure 6 , which is the second embodiment of the present invention, is different from the first embodiment in that the thermal control instrument 300 includes a metal rod 301, an instrument 302 arranged at the end of the metal rod 301, and a rotating member 303 clamped on the peripheral side of the metal rod 301.
[0046] It should be noted that if Figure 2 As shown, the metal rod 301 is used as a temperature detection end, which is inserted into the inner side of the detection tube 101 through the detection end 102 and directly contacts the measured medium. The metal rod 301 contains semiconductor materials with negative temperature coefficients, and its resistance value changes with temperature. By measuring the change in resistance value, the temperature can be accurately determined.
[0047] Preferably, the rotating member 303 is designed as a sphere and is clamped on the circumference of the metal rod 301. A spherical groove matching the rotating member 303 is provided on the limit plate 202. When the thermal control instrument 300 is fixed on the detection end 102 through the flange ring 201, the rotating member 303 is embedded in the spherical groove of the limit plate 202 to achieve fixed-point rotation.
[0048] Through the spherical design of the rotating member 303, the thermal control instrument 300 can freely adjust the angle in multiple directions to meet the needs of different installation positions, especially on the inclined or side-mounted detection tube 101, so that the staff can read the data more easily.
[0049] Furthermore, the limiting plate 202 includes a fixing portion 202a clamped with the flange ring 201, and a limiting portion 202b protruding from the bottom of the fixing portion 202a.
[0050] It should be noted that if Figure 3 As shown, the limit plate 202 is disc-shaped and is divided into two parts, the upper end of which is a fixing part 202a for clamping with the flange ring 201. The limit plate 202 can be limited as a whole on the inner side of the flange ring 201 to ensure good sealing between the thermal control instrument 300 and the detection end 102.
[0051] Furthermore, the fixing portion 202a includes a clamping groove 202a-1 disposed on its circumferential side, a rotation groove 202a-2 disposed on its end, and positioning members 202a-3 disposed on both sides of the rotation groove 202a-2.
[0052] Further, the flange ring 201 includes a key block 201a disposed on the inner side thereof;
[0053] The key block 201a is fixedly engaged with the card slot 202a-1.
[0054] It should be noted that if Figure 4 As shown, rectangular slots 202a-1 are provided on both sides of the fixing portion 202a, which do not penetrate the bottom from the upper end surface, and rectangular key blocks 201a matching the slots 202a-1 are welded on the inner side of the flange ring 201 on the outer side. The flange ring 201 is embedded in the upper end of the slot 202a-1 through the key blocks 201a on both sides, thereby fixing and clamping the limiting plate 202. A rubber gasket can be installed at the bottom of the limiting plate 202 to increase the sealing of the connection.
[0055] Preferably, at the end face axis of the fixed portion 202a, a rotation groove 202a-2 is provided through the plate body of the limiting plate 202, and the rotation groove 202a-2 is a circular groove, providing a deflection space for the inner metal rod 301 to deflect. Secondly, positioning members 202a-3 are provided inside the plate body on both sides of the rotation groove 202a-2 at the axis of the fixed portion 202a, and the positioning members 202a-3 can play a role in fixing the rotating member 303 inside the limiting portion 202b.
[0056] Furthermore, the rotating member 303 includes two groups of hemispherical bodies 303a clamped on the circumference of the metal rod 301, and a connecting rod 303b arranged on one side of the hemispherical body 303a.
[0057] Furthermore, the limiting portion 202b includes a balloon bag 202b-1 disposed at the bottom thereof;
[0058] The balloon bag 202b-1 has a movable limiting hemispherical body 303a.
[0059] It should be noted that if Figure 3 As shown, the rotating member 303 is composed of a hemispherical body 303a symmetrical on both sides, and two groups of connecting rods 303b fixing the hemispherical body 303a. A circular hole with the same width as the metal rod 301 is provided inside the hemispherical body 303a, and an anti-slip sheet can be provided inside the hemispherical body 303a to prevent the rotating member 303 from sliding down on the metal rod 301 after being clamped. Through holes are provided on both sides of the hemispherical body 303a to facilitate the connecting rod 303b to pass through and fix it on the metal rod 301.
[0060] Better, such as Figure 4As shown, the bottom of the fixing part 202a is a limiting part 202b, which can better contain the hemispherical body 303a clamped therein. The limiting part 202b is composed of a balloon bag 202b-1 at the bottom thereof, and the balloon bag 202b-1 has a hemispherical shape inside, and a circular groove is penetrated by the rotating groove 202a-2 on the front side thereof, so that the metal rod 301 can deflect from the front side normally. In addition, the balloon bag 202b-1 is an elastic petal-shaped structure, which is convenient for the metal rod 301 to be installed therein from the bottom.
[0061] Furthermore, the positioning member 202a-3 includes a positioning rod 202a-31 and a driving rod 202a-32 disposed on one side of the positioning rod 202a-31.
[0062] Furthermore, the fixing portion 202a further includes a threaded hole 202a-4 for limiting the driving rod 202a-32, and a movable hole 202a-5 opened on the inner side thereof;
[0063] The upper end of the driving rod 202a-32 is a threaded column Y, which matches with the threaded hole 202a-4.
[0064] Further, the ends of the positioning rod 202a-31 and the driving rod 202a-32 are both ball ends N;
[0065] The other end of the positioning rod 202a-31 is a tip M, and can fix the hemispherical body 303a.
[0066] It should be noted that the positioning member 202a-3 plays a role in positioning and fixing the hemispherical body 303a inside the balloon bag 202b-1. The positioning member 202a-3 is composed of a positioning rod 202a-31 and a driving rod 202a-32. A movable hole 202a-5 is provided on the inner side of the disk of the fixed part 202a from both sides of the disk body, and the movable groove 202a-5 is convenient for inserting and installing the positioning rod 202a-31 from both sides of the disk body of the fixed part 202a. Two threaded holes 202a-4 that can limit the driving rod 202a-32 are provided on the upper end surface of the fixed part 202a. The position of the threaded hole 202a-4 is just above the movable hole 202a-5, which is convenient for the driving rod 202a-32 to limit the positioning rod 202a-31 to act on the hemispherical body 303a.
[0067] Preferably, the upper end of the driving rod 202a-32 is a threaded column Y, and cooperates with the threaded hole 202a-4, so that the driving rod 202a-32 can be screwed into the threaded hole 202a-4 by the rotational force. The ends of the positioning rod 202a-31 and the driving rod 202a-32 are both ball ends N, and the ball ends N of both are directly in contact with each other. Under the rotational force of the driving rod 202a-32 acting on the threaded hole 202a-4, the ball end N of the positioning rod 202a-31 is lowered and squeezed, so that it moves toward the axis of the fixed part 202a. Secondly, the tip M of the positioning rod 202a-31 will directly act on the hemisphere 303a, and the tip M directly touches the hemisphere 3030a to achieve the effect of point positioning, preventing the thermal control instrument 300 from accidentally touching and deflecting when in use.
[0068] When in use, insert the metal rod 301 of the thermal control instrument 300 from the fixed part 202a at the end of the limit plate 202 into the rotating groove 202a-2, so that it is completely extended out of the outside of the limit plate 202b. Ensure that the contact surface between the metal rod 301 and the rotating groove 202a-2 is smooth and there is no jamming. Clamp the hemisphere 303a to the outside of the metal rod 301 through the connecting rod 303b. Ensure that the connection between the hemisphere 303a and the metal rod 301 is firm and not loose. Then clamp the hemisphere 303a from the bottom of the balloon bag 202b-1, so that the hemisphere 303a fits tightly with the spherical groove of the limit plate 202, and the preliminary limit of the metal rod 301 is achieved. Then, the limit plate 202 is fixed to the card slot 202a-1 through the key block 201a and limited to the inner side of the flange ring 201; then, the flange ring 201 is threadedly connected to the detection end 102 to ensure that the interface between the flange ring 201 and the detection end 102 fits tightly to prevent medium leakage.
[0069] Adjust the position of the thermal control instrument 300: Figure 6 As shown, the metal rod 301 can be deflected in the rotation slot 202a-2 under the action of the force F'. The specific steps are as follows:
[0070] Starting from the initial position a, by using an appropriate tool or manually applying a force F', the metal rod 301 is deflected along the direction of the rotation groove 202a-2, and the metal rod 301 can be rotated from position a to position b. Continue to apply the force F' until the metal rod 301 is completely rotated to position c. During this process, ensure that the contact surface between the metal rod 301 and the rotation groove 202a-2 is always smooth without any jamming.
[0071] Conversely, by applying a force F, the metal rod 301 can be moved from position c to position b and finally to position a.
[0072] After adjusting the required angle, use a tool or manually rotate the drive rod 202a-32 to rotate it in the threaded hole 202a-4 and move downward. Under the rotational force of the drive rod 202a-32 acting on the threaded hole 202a-4, it descends and squeezes the ball end N of the positioning rod 202a-31. When the ball end N of the positioning rod 202a-31 is squeezed, the positioning rod 202a-31 will move inward along the preset path, so that it moves toward the axis of the fixed part 202a. Secondly, the tip M of the positioning rod 202a-31 will directly act on the hemisphere 303a, and the tip M will directly touch the hemisphere 303a to achieve the effect of point positioning. Prevent the thermal control instrument 300 from accidentally touching and deflecting during use, and ensure that no deviation occurs during operation.
[0073] In summary, the device significantly improves the stability and reliability of the system by optimizing the installation and adjustment method of the thermal control instrument 300. By clamping the hemisphere 303a to the outside of the metal rod 301 through the connecting rod 303b, and clamping the hemisphere 303a from the bottom of the balloon bag 202b-1, the initial limit of the metal rod 301 is achieved. By applying forces F' and F, the metal rod 301 can deflect freely in the rotating groove 202a-2, from position a to position b, and then to position c, and vice versa. This multi-position adjustment function enables the thermal control instrument 300 to adapt to different working conditions and enhances the flexibility of the system. The modular design is adopted between the components for easy disassembly and replacement. Regularly check the status of the thermal control instrument 300 and the limit plate 202, and replace damaged parts in time to ensure the long-term stable operation of the system and simplify maintenance and repair work.
