Description

Technical Field

[0001] This utility model relates to the field of heating pipe technology, and in particular to a heating pipe connection structure with automatic air venting function. Background Technology

[0002] With rapid economic development and continuous improvement in people's living standards, centralized hot water heating in cities has become the main heating method for people in winter. In hot water heating systems, it is necessary to connect heating pipes and radiators.

[0003] In existing technology, common venting devices for heating pipes mainly use float-type automatic venting valves. These devices typically include a valve body, a float, a vent, and a sealing mechanism. Their working principle is as follows: when gas accumulates in the pipe, causing the water level to drop, the float sinks, causing the valve stem to open the vent and release the gas; after the gas is released, the water level rises, causing the float to return to its original position and the vent to close again. Some improved products add a filter screen to the valve body to prevent clogging by impurities and enhance the float's sensitivity through a lever mechanism. However, the vent position and direction of these devices are fixed, and their function relies on the natural accumulation of gas at the highest point in the pipe. Furthermore, the valve body must be strictly vertical during installation to ensure the float operates correctly.

[0004] The structural characteristics of traditional air vent valves result in significant technical bottlenecks. First, the fixed direction of the vent makes it difficult for the device to adapt to changes in pipe installation angles. For example, in inclined or multi-bend pipes, gas may not effectively converge at the vent, reducing venting efficiency and causing airlock. Second, the installation location of existing devices is limited, requiring them to be placed at the highest point of the piping system. This can lead to redundant pipe routing designs in complex heating systems, increasing construction costs and maintenance difficulties. Furthermore, when the piping system requires multi-angle venting due to terrain differences or building structure limitations, the fixed vent cannot meet dynamic adjustment needs, potentially causing localized gas stagnation and affecting the overall system's thermal circulation efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a heating pipe connection structure with automatic exhaust function, aiming to improve the problem that the exhaust port is difficult to adjust in angle in the prior art.

A spring is sleeved on the outside of each of the two locking pins. Two fixing blocks are fixedly connected to the outside of the metal tube. An activated carbon filter screen is slidably connected to the inside of the metal tube.

[0011] 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.

[0012] Reference Figures 1-2This utility model provides an embodiment of a heating pipe connection structure with automatic venting function, comprising a metal pipe 1, which serves as the main channel for heating gas delivery, providing a stable path for gas flow. An vent valve 3 is fixedly connected to the top of the metal pipe 1, automatically venting air or excess gas from the pipe to prevent air blockage from affecting heating efficiency. Air pumps 4 are fixedly connected to both sides of the metal pipe 1, providing power to drive gas flow within the pipe and ensuring heating gas delivery pressure. Rotating components 5 are fixedly connected to the output ends of both air pumps 4, transmitting power from the air pumps 4 to subsequent components for coordinated operation. A ball tube 6 is rotatably connected to the front of the metal pipe 1, providing a basis for adjusting the angle of the air outlet pipe 9 and enhancing structural flexibility. Fixing blocks 7 are fixedly connected to both sides of the ball tube 6, securing the triangular workpiece 8 and ensuring its structural stability during rotation. Two fixed blocks 7 are rotatably connected to triangular workpieces 8 on their outer sides. The rotation of the triangular workpieces 8, in conjunction with the rotating component 5, drives the ball tube 6 to adjust its angle, thereby changing the direction of the air outlet pipe 9. The front of the ball tube 6 is fixedly connected to the air outlet pipe 9, which is the terminal channel for heating output, delivering the processed gas to the designated heating area. Fixed blocks 10 are fixedly connected to both sides of the air outlet pipe 9, connecting the triangular workpieces 8 and the air outlet pipe 9 to ensure effective power transmission. The end of the triangular workpiece 8 furthest from the rotating component 5 is fixedly connected to the fixed block 10. Through this connection, the triangular workpiece 8 can transmit the power of the rotating component 5 to the air outlet pipe 9, enabling rotational adjustment of the air outlet pipe 9. The side of the triangular workpiece 8 furthest from the air outlet pipe 9 is rotatably connected to the inner wall of the rotating component 5. This rotatable connection allows the rotating component 5 to smoothly drive the triangular workpiece 8, thereby precisely adjusting the angle of the air outlet pipe 9.

[0013] Reference Figures 2-3A pull block 11 is slidably connected to the outside of the metal tube 1. The sliding of the pull block 11 moves the locking pin 12, enabling quick loading and unloading of the activated carbon filter screen 15. Two locking pins 12 are fixedly connected to the rear side of the pull block 11. The locking pins 12 can be inserted into the round hole 17 to fix the limiting block 16, ensuring stable installation of the activated carbon filter screen 15. Springs 13 are fitted on the outer sides of both locking pins 12. The elastic force of the springs 13 allows the locking pins 12 to automatically reset, maintaining the fixed state of the limiting block 16 when no external force pulls the pull block 11. Two fixing blocks 14 are fixedly connected to the outside of the metal tube 1. The fixing blocks 14 provide a fixed fulcrum for the springs 13 and limit the sliding range of the pull block 11, ensuring structural stability. An activated carbon filter screen 15 is slidably connected inside the metal tube 1. The activated carbon filter screen 15 filters impurities in the gas, ensuring the quality of the output gas and preventing impurities from accumulating in the pipe and affecting flow. A limiting block 16 is fixedly connected to the top of the activated carbon filter 15. The limiting block 16 restricts the insertion depth of the activated carbon filter 15, preventing it from going too deep into the pipe. Two circular holes 17 are formed inside the limiting block 16. These holes 17 cooperate with the locking post 12 to achieve quick fixing and disassembly of the activated carbon filter 15. A fixing block 3 14 is fixedly connected to the front side of the limiting block 16. This connection ensures that the spring 13 and the locking post 12 can accurately act on the limiting block 16, guaranteeing a secure fixation. One end of the spring 13 is fixedly connected to the rear side of the pull block 11, and the other end is fixedly connected to the front side of the fixing block 3 14. This two-end fixation allows the spring 13 to stably provide restoring force, ensuring the automatic reset function of the locking post 12. The locking post 12 slides through the fixing block 3 14 and is slidably connected to the inner wall of the circular hole 17. This through-hole design allows the locking post 12 to be accurately inserted into the circular hole 17, effectively fixing the limiting block 16. The limiting block 16 is located on the outside of the metal pipe 1. The outer side is designed to allow operators to quickly access and replace the activated carbon filter 15, improving maintenance efficiency. A support frame 2 is fixedly connected to the bottom end of the metal pipe 1. The support frame 2 provides support for the entire device, ensuring the stability of the structure during operation and preventing the pipe from shifting due to external forces.

[0014] Working principle: When the air pump 4 is started, the rotating part 5 drives the triangular workpiece 8 to rotate, and at the same time, the ball tube 6 drives the air outlet pipe 9 to rotate. The exhaust port can be freely adjusted to adapt to different terrains and pipe installations at different angles. The air outlet angle can also be adjusted according to its own needs. When the gas enters from the metal pipe 1, it is filtered by the activated carbon filter screen 15, which ensures the gas quality requirements and prevents impurities from accumulating in the pipe due to long-term operation. By pulling the pull block 11, the locking post 12 and the round hole 17 are released, which allows for quick replacement of the activated carbon filter screen 15 and ensures its good working performance.

[0015] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
