Specifically, the L-shaped pipeline 3 is connected with the pipeline threaded joint 1 to improve the reliability; the filter screen 2 is convenient to insert into the high-temperature medium pipeline workpiece to prevent the internal particles from entering; the heat dissipation coil 6 cooperates with the main rod 5 to diffuse the heat outward to form the heat dissipation; the mesh reinforcing rib 7 extends to the inside of the first protective cover 9 through the flange mounting disc 8 to form the auxiliary heat dissipation treatment of the pressure instrument 11. In actual use, first, the pipeline threaded joint 1 and the bottom of the filter screen 2 are downwardly inserted into the high-temperature pipeline workpiece, and then the top is connected outside the main rod 5, the pipeline threaded joint 1 is connected with the pressure instrument 11 through the mesh reinforcing rib 7, the heat conduction base 10 and the pressure instrument 11 above, when the heat is transmitted through the pipeline workpiece below, is contacted by the first heat dissipation fin 13 inside the pipeline threaded joint 1, and is secondarily heat dissipated through the second heat dissipation fin 15, reduces the high temperature, and performs the primary heat dissipation, then the heat is gradually conducted to the main rod 5 under the connection, and the heat is continuously intercepted through the auxiliary action of the heat dissipation fin 35 of the middle end, the hole 25 and the inside middle rod 31, the supporting thin strip 24 outside the main rod 5, greatly improves the heat dissipation effect, and finally the heat is finally heat dissipated through the cold heat dissipation fin 32, according to the heat dissipation structure constructed in sequence, the heat conducted to the pressure instrument 11 is minimized. Since the environment temperature of the pressure instrument 11 is relatively low, the condensed water is mainly generated near the cold heat dissipation fin 32 inside the first protective cover 9, wherein the water vapor in the air is condensed into water on the surface of the cold heat dissipation fin 32 with low temperature, the condensed water is guided along the flow guide groove 33 and the limiting hole 34 on the flange mounting disc 8, and finally falls into the recovery disc 4 to be uniformly collected and discharged.

[0022] As shown in Figures 2 to 4 The condensing member includes: The sleeve 12 is arranged outside the main rod 5. The second protective cover 14 is arranged above the sleeve 12. A flow guide pipe 16 is arranged in the sleeve 12.

[0023] The first heat-conducting member comprises: A first heat-dissipating fin 13 is arranged below the sleeve 12. A first groove is formed in the inner side of the top of the sleeve 12 and is adapted to the second protective cover 14. A second heat-dissipating fin 15 is arranged below the second protective cover 14. A second groove is formed in the inner side of the bottom of the sleeve 12 and is adapted to the first heat-dissipating fin 13. Specifically, the sleeve 12 is located inside the recovery tray 4 and has a through groove formed in the center thereof, the first heat-dissipating fin 13 is adapted to the outer side of the main rod 5 at the center, the main rod 5 penetrates the inside of the first heat-dissipating fin 13 and is connected with the pipe threaded joint 1, the four corners of the first heat-dissipating fin 13 and the second heat-dissipating fin 15 are provided with arc corners to facilitate the flow of condensed water downward, and the bottom of the sleeve 12 and the bottom of the second protective cover 14 are provided with guide grooves. In actual operation, when the high-temperature medium in the pipe workpiece flows upward, the heat will first contact the first heat-dissipating fin 13 on the outer side of the main rod 5, the heat is initially reduced by being diffused outward through the first heat-dissipating fin 13, is then conducted to the inside of the second protective cover 14 through the sleeve 12, and is diffused again by contacting the second heat-dissipating fin 15, so that the heat is cooled before entering the connector, the temperature difference is the largest, the heat dissipation is obvious, the subsequent heat conduction is prevented from being more, and the effect of protecting the temperature from being reduced first is achieved. In installation, the first heat-dissipating fin 13 is first sleeved on the outer side of the main rod 5, and then the second heat-dissipating fin 15 is placed in the sleeve 12 in sequence, the second heat-dissipating fin 15 is located above the first heat-dissipating fin 13, at this time, the installation is completed by screwing the second protective cover 14 to the first groove in the upper side of the sleeve 12, and the second protective cover 14 can be rotated for quick disassembly, so that the subsequent disassembly and cleaning are facilitated. When the environment is harsh, the high-temperature propagates upward, and may be accompanied by contaminated particles, the particles contact the lower surface of the recovery tray 4 and are blocked by the recovery tray 4. When the second heat-dissipating fin 15 and the first heat-dissipating fin 13 have condensed water, the water flows to the upper groove of the inner wall of the sleeve 12 along the arc corner, enters the inside of the flow guide pipe 16 through the groove, and then flows into the recovery tray 4 to form collection, so that the condensed water is treated in time; it should be noted that the upper groove of the sleeve 12 is designed to be inclined with one side being higher than the other side and is in contact with the flow guide pipe 16.

[0024] As shown in Figures 6 to 7 The uniform member comprises: A middle rod 31 is arranged in the inside of the main rod 5. The guide rod 27 is provided outside the clamping plate 26; The clamping plate 26 is provided outside the middle rod 31; The dustproof part is provided outside the clamping plate 26 to block the heat dissipation hole; The dustproof part comprises: The reset sheet 28 is provided outside the guide rod 27; The memory alloy spring 29 is provided on the inner wall of the main rod 5; The blocking plate 30 is provided at one end of the memory alloy spring 29 and outside the guide rod 27; The second heat dissipation part comprises: The hole 25 is provided on the outer surface of the main rod 5 and between the memory alloy springs 29; The middle end heat dissipation fin 35 is provided outside the main rod 5.

[0025] Specifically, the guide rod 27 is provided to facilitate faster heat dissipation outside, facilitate the entry of heat into the main rod 5, and facilitate the installation of the clamping plate 26 on the guide rod 27; the middle rod 31 is conducive to the stability of the plurality of guide rods 27; the main rod 5 is used for up-down connection to facilitate the improvement of reliability; the reset sheet 28 facilitates the provision of guidance for the memory alloy spring 29, facilitates the prevention of damage during the long-term extension or shortening of the spring, and facilitates the improvement of stability; the blocking plate 30 is filled in the hole 25 on the outer surface of the main rod 5 by default to ensure the smoothness of the outer side of the main rod 5 and prevent dust from entering the inside of the main rod 5 to cause dirt; the middle end heat dissipation fin 35 is a spiral heat dissipation fin, the spiral shape increases the path and turbulence degree of airflow flowing through, has good heat dissipation effect, and has no sharp right angle, so that the stress distribution is more uniform; the hole 25 facilitates the direct impact on the heat dissipation coil pipe 6 to reduce the dust that may be adhered to the outside of the heat dissipation coil pipe 6; the low-temperature reset of the extruded memory alloy spring 29 retracts to pull the blocking plate 30 to close the hole 25, thereby playing a dustproof role; the blocking plate 30 is opened to open the hole 25 when the temperature is high, thereby playing a hole opening and heat dissipation role.

[0026] In actual application, after the main rod 5 is inserted into the first heat dissipation fin 13, heat enters the main rod 5 through the effect of heat transfer, the heat is accelerated to diffuse through the gaps between the plurality of guide rods 27, and the heat is dissipated outside through the hole 25. In addition, the external middle end heat dissipation fin 35 homogenizes the heat, facilitates the reduction of high temperature through distributed heat dissipation, plays a temperature reduction effect, and facilitates the improvement of heat dissipation effect. If the equipment is not working or the environment is cold, when the temperature is lower than a certain set value, for example, 50℃, the spring retracts to pull the blocking plate 30 to block the hole 25, thereby preventing dust from entering, facilitating the entry of dust and the like into the outer surface of the main rod 5, and playing a supplementary dustproof role. When the temperature rises to the working temperature, for example, more than 80℃, the memory alloy spring 29 is in the elongated state, pushing the blocking plate 30 to open the hole 25, and the hole 25 is opened to enhance heat dissipation, ensuring that the heat can be smoothly dissipated.

[0027] As shown in Figures 3 to 5 , the heat-rattling piece comprises: The telescopic mounting cylinder 20 is arranged inside the recovery disc 4; The temperature sensor 19 is arranged inside the recovery disc 4 and outside the telescopic mounting cylinder 20; The electric telescopic rod 21 is arranged inside the telescopic mounting cylinder 20; The torsion bar 23 is arranged outside the telescopic mounting cylinder 20; The supporting thin bar 24 is arranged outside the torsion bar 23 and inside the recovery disc 4; The pick plate 22 is arranged above the electric telescopic rod 21; Specifically, the telescopic mounting cylinder 20 is provided with a processor outside, which is beneficial to sensing the electric energy of the temperature sensor 19 and facilitating timely driving processing; the temperature sensor 19 is arranged inside the recovery disc 4, which is beneficial to monitoring the heat dissipation efficiency; if the temperature of the middle-end heat dissipation fin 35 is continuously high, it indicates that the heat dissipation may be poor due to dust accumulation, and the processor is triggered to drive the electric telescopic rod 21 to clean the dust; The electric telescopic rod 21 is provided with a motor at the bottom, which converts electric energy into rotary mechanical energy by driving the motor, which is convenient for timely extending the electric telescopic rod 21, which is not described in detail; the end of the pick plate 22 is arc-shaped, which is matched with the shape of the heat dissipation coil pipe 6, so as to ensure sufficient contact and not damage the heat dissipation coil pipe 6 during operation; In actual application, since the heat dissipation coil pipe 6 is arranged outside the main rod 5, dust is easy to accumulate outside for a long time, so when the temperature of the middle-end heat dissipation fin 35 inside the recovery disc 4 is continuously high, the electric signal is fed back to the processor, and the electric telescopic rod 21 is driven upward by the processor, the electric telescopic rod 21 pushes the pick plate 22 to extrude the heat dissipation coil pipe 6 upward, the heat dissipation coil pipe 6 is extruded and forms a shaking, and the dust outside is shaken off to the inside of the recovery disc 4 under the action of the shaking force, so that the device has the purpose of reducing the dust outside the heat dissipation coil pipe 6; the supporting thin bar 24 is used to support the telescopic mounting cylinder 20, so as to prevent unstable situation and improve the reliability.

[0028] As shown in Figures 1 to 2 , Figure 8 , the third heat-rattling piece comprises: The cold heat dissipation fin 32 is arranged inside the first protective cover 9; The flow guide groove 33 is arranged below the first protective cover 9; The limiting hole 34 is arranged inside the flange mounting disc 8; The flange mounting disc 8 is provided with a through hole in the center; The net reinforcing rib 7 is provided with a plurality of gaps in the inside; The threaded pipe 36 is rotatably arranged in the center of the heat-conducting base 10; The heat-conducting base 10 is provided with an internal thread in the center, which is matched with the threaded pipe 36.

[0029] Specifically, the flange mounting disc 8 is provided with a limiting hole 34 on both sides in the inside, which is aligned with the vertical flow guide groove 33; the net reinforcing rib 7 is connected with the cold heat dissipation fin 32, which facilitates the heat transfer to the surrounding of the middle rod 31, improves the stability of the connection with the main rod 5, and dissipates heat in time; the threaded pipe 36 facilitates the installation of the first protective cover 9 at the bottom of the heat-conducting base 10, and facilitates the disassembly or installation; In the actual application process, when the connector main rod 5 conducts heat from the pipeline threaded joint 1 to the position of the cold end heat-conducting base 10, the cold heat dissipation fin 32 dissipates the accumulated heat to the air, thereby completing the heat dissipation of the cold end; when the condensed water is generated, it moves to both sides along the outer edge of the cold heat dissipation fin 32, flows downward through the flow guide groove 33, and then flows in the recovery disc 4 through the flange mounting disc 8, thereby completing the recovery of the condensed water.

[0030] Working principle: The hot end heat dissipation part is the first line of defense for the connector to contact the high-temperature medium, which is located above the pipeline threaded joint 1 and inside the recovery disc 4. Heat interception and initial diffusion: When the heat of the high-temperature medium is conducted upward through the pipeline workpiece, it is first contacted by the first heat dissipation fin 13 located at the front end. These fins have a large surface area, which can quickly absorb heat and diffuse it to the outside air, achieving initial cooling. Secondary heat dissipation and thermal isolation: The remaining heat is conducted to the area of the second protective cover 14 inside the sleeve 12 and is subjected to secondary heat dissipation by the second heat dissipation fin 15. This design takes advantage of the largest temperature difference at the inlet to provide powerful cooling before the heat enters the connector main body, effectively reducing the total amount of heat conducted backward. Physical protection and condensed water flow guide redundancy design: Anti-particle: The recovery disc 4 acts as a physical barrier to block the contaminated particles that rise with the hot air flow, preventing them from entering the core of the connector. Although condensed water is mainly generated at the cold end, the corners of the hot end heat dissipation fin are designed with an arc angle, and the bottom of the sleeve 12 and the second protective cover 14 are also provided with a guide groove. In case condensed water is generated, it can ensure that it flows smoothly into the recovery disc 4 along the flow guide pipe 16, avoiding local liquid accumulation.

[0031] The heat after primary heat dissipation is conducted upward along the main rod 5 and enters the middle end heat dissipation part. This part is the main heat dissipation area and integrates the intelligent dust prevention function. After the heat enters the main rod 5, it is dispersed by the structure composed of the middle rod 31 and the plurality of guide rods 27 inside the main rod 5, accelerating the uniform distribution of heat in the rod body, laying the foundation for rapid heat dissipation; The uniformly distributed heat is dissipated outward through the outer wall of the main rod 5 and the holes 25 in the open state. The middle end heat dissipation fins 35 spirally arranged on the outer wall greatly increase the contact area and turbulence effect with the air, achieving high-efficiency heat dissipation. At the same time, the heat dissipation coil pipe 6 also works cooperatively to further drive the heat outward. High temperature working state > 80℃: When the temperature rises above the working threshold such as 80℃, the memory alloy spring 29 is heated and elongated, generating a pushing force to push the blocking plate 30 to move, thereby opening the holes 25 on the wall of the main rod 5. At this time, the heat dissipation path is unobstructed, giving priority to heat dissipation efficiency, with the characteristics of intelligent self-adaptation.

[0032] Low temperature dormant state < 50℃: When the device stops working, the temperature drops below the low temperature threshold such as 50℃, the memory alloy spring 29 is retracted and reset, pulling the blocking plate 30 back to position, tightly blocking the holes 25. This design perfectly solves the contradiction between high-efficiency heat dissipation and long-term dust prevention, protecting the internal cleanliness of the connector during the non-working period; The residual heat reaching the top of the connector is finally treated in the cold end heat dissipation part, and the condensate water problem caused by heat dissipation is solved; The heat is conducted to the cold heat dissipation fins 32 through the mesh reinforcing ribs 7. The fins are located inside the first protective cover 9, below the pressure instrument 11, and finally dissipate the heat to the air, ensuring that the heat transferred to the installation base of the pressure instrument 11 is minimized, providing the best working temperature environment for it; Because the temperature at the end of the pressure instrument 11 is relatively low, water vapor in the air is easy to condense into water on the surface of the cold heat dissipation fins 32. The condensate water flows along the edge of the fins to the flow guide groove 33 at the bottom of the first protective cover 9, then drips downward through the limiting hole 34 on the flange mounting disc 8, and finally flows into the recovery tray 4. The recovery tray 4 plays a role in concentrating and discharging condensate water, preventing water erosion of parts or other damage caused by dripping; To deal with the problem of dust accumulation on the outside of the heat dissipation coil pipe 6 during long-term use, the connector is equipped with an automatic dust removal system based on temperature feedback; The temperature sensor 19 arranged inside the recovery tray 4 continuously monitors the temperature of the middle end heat dissipation area. When it is found that the temperature is continuously abnormally high, the processor determines that the decrease in heat dissipation efficiency is likely caused by dust accumulation; The processor immediately starts the electric telescopic rod 21, which is pushed out upward. The end of the cantilever plate 22 at the top of the electric telescopic rod 21 is designed in an arc shape to adapt to the shape of the coil pipe and press the heat dissipation coil pipe 6 upward, causing it to vibrate slightly, thereby shaking off the dust attached to its outer surface into the recovery tray 4 below, together with the condensate water, and being discharged from the system.

[0033] The foregoing merely illustrates the principles of the application and application of its more prominent features. Those skilled in the art will appreciate that the application is not limited to the embodiments described and illustrated and that many changes and modifications will occur to them without departing from the spirit and scope of the present application.
