Description

Technical Field

[0001] This utility model relates to the field of water leakage prevention technology, and in particular to a water leakage prevention device for a heating pipe air vent valve. Background Technology

[0002] Currently, after a building project is completed and enters its first heating cycle, it's common for the automatic air vent valves in the heating pipes to leak water before the venting process is complete. Analysis shows this is mostly due to impurities in the new pipes or water quality, causing blockages in the automatic air vent valves and preventing proper venting. Furthermore, the vent nozzles continue to spray water under pipe pressure. This leakage can damage surrounding building materials and equipment. Even if it occurs during working hours and someone notices it, a ladder is needed to manually close the valve above the pipes. The risk of damage to surrounding building materials and equipment cannot be guaranteed during this period. If this problem occurs at night, outside of working hours, the losses will be even greater.

[0003] To address the aforementioned issues, we propose a leak-proof device for air vent valves in heating pipes. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the background art by proposing a water leakage prevention device for the air vent valve of heating pipes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a water leakage prevention device for a heating pipe air vent valve, comprising an original heating pipe air vent valve, an automatic heating pipe air vent valve fixedly connected to the top of the original heating pipe air vent valve, a steel water collector fixedly connected to the outer side of the original heating pipe air vent valve, a manual valve fixedly installed on the outer wall of the original heating pipe air vent valve, a solenoid valve fixedly installed on the outer wall of the original heating pipe air vent valve, a liquid level sensor signal switch fixedly connected to the left side wall of the steel water collector, a hanging rod fixedly connected to the bottom of the liquid level sensor signal switch, a wall-mounted audible and visual alarm fixedly connected to the bottom of the hanging rod, and a transmission device provided on the outer side of the original heating pipe air vent valve.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-3 A leak-proof device for a heating pipe vent valve includes an original heating pipe vent valve 1, an automatic vent valve 3 fixedly connected to the top of the original heating pipe vent valve 1, a steel water collector 2 fixedly connected to the outside of the original heating pipe vent valve 1, a manual valve 6 fixedly installed on the outer wall of the original heating pipe vent valve 1, a solenoid valve 13 fixedly installed on the outer wall of the original heating pipe vent valve 1, a liquid level sensor signal switch 17 fixedly connected to the left side wall of the steel water collector 2, a hanging rod 4 fixedly connected to the bottom of the liquid level sensor signal switch 17, a wall-mounted audible and visual alarm 5 fixedly connected to the bottom of the hanging rod 4, a transmission device on the outside of the original heating pipe vent valve 1, an opening at the bottom of the steel water collector 2, a manual drain valve 16 fixedly connected to the bottom of the steel water collector 2 below the opening, the manual valve 6 located below the solenoid valve 13, and a sealing ring 14 at the connection between the opening and the manual drain valve 16. After the water flows into the steel water collector 2, the sealing ring 14 can improve the sealing between the steel water collector 2 and the manual drain valve 16, and also prevent the water from flowing to the outside of the steel water collector 2. When the original heating pipe air vent valve 1 fails to work properly and leaks, the water will flow into the steel water collector 2. When the water level reaches a certain height, it will trigger the liquid level sensor signal switch 17, which will then cause the added solenoid valve 13 to start working and close the manual valve 6 through the transmission device. At the same time, the signal source will also trigger the pre-installed wall-mounted audible and visual alarm 5. In this way, when the heating pipe automatic air vent valve 3 fails to complete the air venting work and water spraying occurs, it can ensure that the surrounding decoration materials, instruments and equipment are protected at the source. When the wall-mounted audible and visual alarm 5 is triggered, the staff can find out the fault of the heating pipe automatic air vent valve at the first time. When repairing, the staff can open the manual drain valve 16, and after the water is drained, the repair can be carried out.

[0019] The transmission device includes a support plate 8. A fixing plate 7 is fixedly connected to the outer wall of the original heating pipe exhaust valve 1. The support plate 8 is connected to the fixing plate 7 by two screws 15. The support plate 8 has an arc-shaped opening. The manual valve 6 has a plug hole. A connecting rod 12 is inserted into the plug hole. A motor 9 is fixedly connected to the outer wall of the support plate 8. A connecting plate 10 is fixedly connected to the drive end of the motor 9. The connecting rod 12 contacts the connecting plate 10 through the arc-shaped opening. The connecting plate 10 is connected to the connecting rod 12 by screw 11. The fixing plate 7 is located below the manual valve 6. The two screws 15 are located on the left and right sides of the bottom of the fixing plate 7. After the solenoid valve 13 is started, it will drive the connecting plate 10 to rotate through the motor 9. The connecting plate 10 will drive the connecting rod 12 to move along the arc-shaped opening. The connecting rod 12 will drive the manual valve 6 to rotate, thereby closing the original heating pipe exhaust valve 1.

[0020] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0021] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
