Description

Technical Field

[0001] This utility model relates to the field of air venting of radiators in heating facilities, and particularly to an air venting device for radiators in heating facilities. Background Technology

[0002] The air vent (air valve) of a radiator is a key component of the heating system. Its main function is to remove accumulated air, ensure normal circulation of hot water, and improve heat dissipation efficiency.

[0003] The existing air venting devices for radiators in heating systems require users to use a key or screwdriver to turn the knob counterclockwise to open the vent. Air is then expelled through the small hole under pressure, accompanied by a flow of water. Once the water flow stabilizes (without air bubbles), the valve is immediately turned clockwise to close the vent. However, in actual use, during manual air venting, a small amount of liquid sprays out from the radiator, and since there is only one vent, this liquid splashes directly onto the floor, walls, or furniture, requiring additional cleaning work. This increases the workload and time required for the air venting process.

[0004] Therefore, it is necessary to propose a venting device for radiators in heating systems to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a venting device for radiators in heating facilities to solve the problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a venting device for a radiator in a heating facility, comprising an automatic venting valve, an outlet pipe fixedly connected to the outlet end of the automatic venting valve, a U-shaped air pipe fixedly connected to the end of the outlet pipe away from the outlet end of the automatic venting valve, a leakage pipe fixedly connected to the bottom end of the U-shaped air pipe, and the U-shaped air pipe and the leakage pipe being internally interconnected, a quick-connect mechanism being provided at the bottom end of the leakage pipe, and a liquid collection mechanism being provided at the bottom of the quick-connect mechanism; The quick-connect mechanism includes a cylindrical sleeve, a slanted locking block, an L-shaped pull plate, and a spring. The end of the leaking pipe away from the U-shaped air pipe is fixedly connected to the cylindrical sleeve. The slanted locking block is slidably connected inside the cylindrical sleeve. The slanted locking block has an inclined surface on the side near the axis of the cylindrical sleeve. The side of the slanted locking block away from the inclined surface is fixedly connected to the L-shaped pull plate. Springs are fixedly connected to both the slanted locking block and the cylindrical sleeve. A liquid collection mechanism is provided at the end of the cylindrical sleeve away from the leaking pipe. The liquid collection mechanism includes a liquid inlet tank, a connecting groove tube, and a limiting strip. The connecting groove tube is inserted into the inner wall of the cylindrical sleeve. The liquid inlet tank is fixedly connected to the side of the connecting groove tube away from the cylindrical sleeve, and the limiting strip is fixedly connected to the side of the connecting groove tube close to the cylindrical sleeve.

[0007] Preferably, the cylindrical sleeve has a first through groove that radially extends from the connecting groove tube, and the inclined block is slidably connected in the first through groove.

[0008] Preferably, the inclined surface structure of the inclined card block is disposed on the side near the connecting groove tube, and the connecting groove tube is provided with a second through groove near the side of the inclined card block, and the inclined card block is partially inserted into the second through groove.

[0009] Preferably, the inclined surface structure of the inclined block is close to the side of the connecting groove tube, and the connecting groove tube is provided with a second through groove close to the side of the inclined block, and the inclined block is partially inserted into the second through groove.

[0010] Preferably, the leakage pipe, cylindrical sleeve, connecting groove pipe, and inlet tank are all arranged on the same axis, and the interiors of the leakage pipe, cylindrical sleeve, connecting groove pipe, and inlet tank are all interconnected. A return pipe is fixedly connected to the side of the inlet tank away from the connecting groove pipe, and a one-way valve is fixedly connected to the end of the return pipe away from the inlet tank.

[0011] The technical effects and advantages of this utility model are as follows: During use, this utility model prevents liquid from spraying out through a U-shaped tube, thus avoiding liquid spraying out during the venting process. The sprayed liquid gathers at the bottom of the U-shaped tube and flows into the liquid inlet tank through the drain pipe, preventing the liquid from splashing directly onto the ground, walls, or furniture, thereby eliminating the need for additional cleaning work. This reduces the tediousness and time required for workers during the venting operation. When it is necessary to clean the liquid inlet tank, simply pull the L-shaped pull plate to disengage the inclined locking block from the connecting groove tube, and the liquid inlet tank can be removed. The collected liquid is safely returned to the system through the design of the return pipe and one-way valve, reducing water waste and heat loss. Attached Figure Description

[0017] This utility model provides, for example Figures 1-4 The device shown is an air venting device for a radiator in a heating system. It includes an automatic air venting valve 1, with an air outlet pipe 2 fixedly connected to the outlet end of the valve 1. This valve 1 is used to vent accumulated air from the radiator, preventing air resistance from affecting the heating effect. The specific composition and working principle of the automatic air venting valve 1 are existing technologies and will not be described in detail here. Specifically, in the initial state (no air) of the radiator or pipes, the radiator or pipes are filled with water. A float rises due to the buoyancy of the water, and the vent is blocked by the float, remaining closed to prevent leakage. When air enters, it gradually accumulates in the valve body due to its low density, causing the water level to drop. The float then descends with the water level, automatically opening the vent and venting the air. After the air is vented, water re-enters the valve body, the float rises, and the vent automatically closes. Therefore, the entire process requires no manual intervention, achieving fully automatic air venting. A U-shaped air pipe 3 is fixedly connected to one end of the air outlet pipe 2 away from the air outlet end of the automatic air release valve 1. Its U-shaped structure prevents the small amount of liquid carried out during the air release process from being sprayed out. A drain pipe 4 is fixedly connected to the bottom end of the U-shaped air pipe 3 to collect and discharge the small amount of liquid carried out during the air release process. The U-shaped air pipe 3 and the drain pipe 4 are internally interconnected. A quick-connect mechanism 5 is provided at the bottom end of the drain pipe 4 to facilitate quick disassembly and assembly of the liquid collection mechanism 6 for cleaning. A liquid collection mechanism 6 is provided at the bottom of the quick-connect mechanism 5 for temporary storage and centralized treatment of the discharged liquid.

[0018] The quick-connect mechanism 5 includes a cylindrical sleeve 51, a slanted locking block 52, an L-shaped pull plate 53, and a spring 54. The end of the leakage pipe 4 away from the U-shaped air pipe 3 is fixedly connected to the cylindrical sleeve 51, serving as the main connection body. The slanted locking block 52 is slidably connected inside the cylindrical sleeve 51 to achieve quick locking and unlocking functions. The slanted locking block 52 has a slanted surface on the side near the axis of the cylindrical sleeve 51, and an L-shaped pull plate 53 is fixedly connected on the side of the slanted locking block 52 away from the slanted surface, providing a manual operation interface. Springs 54 are fixedly connected to the opposite surfaces of the slanted locking block 52 and the cylindrical sleeve 51 to provide a reset spring force to maintain the locked state. A liquid collection mechanism 6 is provided at the end of the cylindrical sleeve 51 away from the leakage pipe 4. The liquid collection mechanism 6 includes an inlet tank 61, a connecting groove pipe 62, and a limiting strip 63. The connecting groove pipe 62 is inserted into the inner wall of the cylindrical sleeve 51 to form a sealed connection channel. The inlet tank 61 is fixedly connected to the side of the connecting groove pipe 62 away from the cylindrical sleeve 51 for collecting and storing liquid. The limiting strip 63 is fixedly connected to the side of the connecting groove pipe 62 near the cylindrical sleeve 51 to ensure the correct installation direction.

[0019] During use, when air accumulates inside the radiator, the automatic air release valve 1 opens, and the gas is discharged sequentially through the air outlet pipe 2 and the U-shaped air pipe 3. The small amount of liquid carried out accumulates at the bottom of the U-shaped air pipe 3 and flows into the liquid collection mechanism 6 through the leakage pipe 4. When cleaning is required, manually pull the L-shaped pull plate 53 to disengage the inclined locking block 52 from the connecting groove pipe 62, and the liquid collection mechanism 6 can be removed.

[0020] The cylindrical sleeve 51 has a first through groove that is radially through the connecting groove tube 62, providing a sliding track for the inclined block 52; and the inclined block 52 is slidably connected in the first through groove to ensure that the inclined block 52 moves along a predetermined trajectory.

[0021] During use, when installing the liquid collection mechanism 6, the inclined locking block 52 slides in the first through groove to ensure accurate and reliable locking action.

[0022] The inclined surface structure of the inclined locking block 52 is set on the side near the connecting groove tube 62 to realize the self-locking function; and the connecting groove tube 62 has a second through groove on the side near the inclined locking block 52 to accommodate the locking end of the inclined locking block 52; and the inclined locking block 52 is partially inserted into the second through groove to form a mechanical interlock.

[0023] During use, when installing, the inclined surface of the inclined block 52 automatically slides into the second through groove after contacting the connecting groove tube 62; when disassembling, the L-shaped pull plate 53 must be pulled first to make the inclined block 52 exit the second through groove.

[0024] The cylindrical sleeve 51 has a third through groove inside, near the end of the liquid inlet tank 61, for positioning the limiting strip 63; and the limiting strip 63 is inserted into the third through groove to ensure that the liquid collection mechanism 6 is installed in the correct direction.

[0025] During use, when installing the liquid collection mechanism 6, the limit strip 63 must be aligned with the third through groove to be fully inserted to prevent incorrect installation.

[0026] The leakage pipe 4, cylindrical sleeve 51, connecting groove pipe 62, and inlet tank 61 are all set on the same axis to ensure smooth liquid flow. The leakage pipe 4, cylindrical sleeve 51, connecting groove pipe 62, and inlet tank 61 are all interconnected to form a complete liquid discharge channel. A return pipe 7 is fixedly connected to the side of the inlet tank 61 away from the connecting groove pipe 62. The return pipe 7 is connected to the bottom of the inlet tank 61 to provide a path for the collected liquid to return to the heating system. A one-way valve 8 is fixedly connected to the end of the return pipe 7 away from the inlet tank 61. It is installed on the return pipe 7 and one end is connected to the system return water pipe. It only allows the liquid to flow from the inlet tank back to the return water pipe of the heating system to prevent hot water from flowing back into the cooled liquid collection mechanism 6 or even spraying out from the exhaust port.

[0027] During use, the liquid flows from the leak pipe 4 through the cylindrical sleeve 51 and the connecting groove pipe 62 into the liquid inlet tank 61 in sequence, and the whole process is unobstructed.

[0028] Furthermore, during the aforementioned usage process, the U-shaped tube prevents liquid from spraying out, and the U-shaped structure avoids liquid spraying out during the venting process. The sprayed liquid accumulates at the bottom of the U-shaped air tube 3 and flows into the liquid inlet tank 61 through the drain pipe 4, preventing the liquid from splashing directly onto the ground, walls, or furniture, thus eliminating the need for additional cleaning work. This reduces the tediousness and time required for workers during the venting operation. When it is necessary to clean the liquid inlet tank 61, simply pull the L-shaped pull plate 53 manually to disengage the inclined locking block 52 from the connecting groove pipe 62, and the liquid inlet tank 61 can be removed.
