Description

Technical Field

[0001] This application relates to the field of heating system equipment technology, and more specifically, to a shut-off valve controller for heating pipes. Background Technology

[0002] Heating is a common heating device in buildings in northern China. It works by sending hot water through heating pipes to the radiators in each household, and then releasing the heat from the hot water through the radiators to raise the temperature in the room.

[0003] In existing technologies, heating companies typically control the total volume and temperature of hot water in the heating pipes based on the outside temperature. This makes it difficult to tailor temperature adjustments to the specific needs of each household, resulting in some users experiencing insufficient indoor temperatures or others feeling excessively hot. As society becomes increasingly technologically advanced, the demand for intelligent heating control is also growing. However, upgrading heating pipes to be intelligent is costly. Therefore, intelligent shut-off valve controllers could be designed to intelligently control the shut-off valves in each household, thereby controlling the amount of hot water entering each home. However, the pipe and valve connections vary across different communities, making it difficult to design a universal controller to manage all these shut-off valves.

[0004] Therefore, it is necessary for the inventors to design a new shut-off valve controller for heating pipes to overcome the above problems. Summary of the Invention

The chip board is fixedly disposed inside the housing and electrically connected to the drive component. The controller also includes a snap-fit ​​component, one end of which is detachably connected to the output shaft of the drive component, and the other end of which is snapped into the valve stem rotation handle of the shut-off valve.

[0031] like Figures 1 to 4 As shown, a shut-off valve controller for a heating pipe 8 includes a housing 1 and a chip board 2. A clamping component for clamping onto the heating pipe 8 is slidably disposed at the bottom of the housing 1. A drive component is fixedly disposed inside the housing 1. The axis of the output shaft of the drive component coincides with the axis of the valve stem 3 of the shut-off valve. The chip board 2 is fixedly disposed inside the housing 1 and electrically connected to the drive component. It also includes a snap-fit ​​component 5. One end of the snap-fit ​​component 5 is detachably connected to the output shaft of the drive component, and the other end is snapped into the valve stem rotation handle 18 of the shut-off valve.

[0032] Specifically, chip board 2 receives the room temperature signal and controls the working state of the drive component based on the temperature signal. The output end of the drive component drives the snap-fit ​​5 to rotate, which in turn drives the valve stem rotation handle 18 to rotate, thereby regulating the hot water flow in the valve. When installing this controller, first select a suitable snap-fit ​​5 according to the type of valve stem rotation handle 18 and install it on the output shaft of the drive component. Then, align the output shaft axis of the drive component with the axis of the valve stem 3. Next, adjust the position of the clamping component so that it clamps onto the pipe at the end of the locking valve and is fixedly connected to the housing 1, thus completing the installation of the entire device. It should be noted that the detachable connection of the snap-fit ​​5 is for selecting the shape of the snap-fit ​​5. For example, for a long, narrow valve stem rotation handle 18, such as... Figure 3As shown, the snap-fit ​​component 5 can be clamped at both ends of the rotating handle in a clamping plate shape, and rotating the clamping plate can achieve the effect of rotating the valve stem and rotating the handle 18; as shown Figure 5 As shown, if the valve stem rotation handle 18 is in the form of a handwheel, the locking member 5 can be designed with multiple inserts. After inserting into the handwheel, rotating the locking member 5 can also achieve the effect of rotating the valve stem and rotating the handle 18. Other forms will not be described in detail here. In addition, the clamping component is set to be adjustable at the bottom of the housing 1 because different locking valves have different lengths, and it is difficult to fix this device to the valve, but it is more convenient to fix it to the pipeline. Therefore, the clamping position of the clamping component is set on the pipeline to accommodate various different heating pipelines 8.

[0033] This embodiment addresses the installation issues on valves and pipes of different specifications by setting the position of the clamping component to be adjustable, and sets the snap-fit ​​5 to be detachably connected to the output shaft of the drive component so that the snap-fit ​​5 can be adapted to the operation mode of the valve stem rotation handle 18 of different locking valves. Thus, this controller can be installed on the pipe valves of various different heating pipe systems 8.

[0034] The clamping assembly includes a base plate 6 and two arc-shaped positioning plates 7. The base plate 6 is fixedly disposed at the bottom of the housing 1. A locking assembly is fixedly disposed between the upper ends of the two arc-shaped positioning plates 7 and the base plate 6. The middle parts of the two arc-shaped positioning plates 7 abut against the outer wall of the heating pipe 8. The bottoms of the two arc-shaped positioning plates 7 are fixedly connected by a fastener. The locking assembly includes a socket 9 and a positioning screw 10. The socket 9 is formed at the upper end of the arc-shaped positioning plates 7 and is arranged in a linear array on the base plate 6. The positioning screw 10 passes through the socket 9 on the two arc-shaped positioning plates 7 and one of the socket 9 on the base plate 6 and is threadedly connected to a nut 11. The opposite sidewalls of the two arc-shaped positioning plates 7 abut against the sidewall of the base plate 6. The fastener is a bolt assembly. Specifically, after adjusting the insertion hole 9 on the arc-shaped positioning plate 7 to be aligned with the insertion hole 9 on the base plate 6, the positioning screw 10 is inserted to lock the position. Then, the middle part of the arc-shaped positioning plate 7 is attached to the outer wall of the pipe, and the upper and lower ends of the arc-shaped positioning plate 7 are locked by the screw nut 11 and bolt assembly, thereby realizing the fixed connection between the two arc-shaped positioning plates 7 and the pipe and the base plate 6.

[0035] The drive assembly includes a motor 12 and a reducer 13 fixedly disposed inside the housing 1. The output shaft of the motor 12 is fixedly connected to the input end of the reducer 13, and the output end of the reducer 13 is detachably connected to the snap-fit ​​member 5. Specifically, the output shaft of the motor 12 drives the snap-fit ​​member 5 to rotate after being reduced in speed by the reducer 13.

[0036] The output shaft of the reducer 13 is fixedly connected to a connecting plate 14. Both the connecting plate 14 and the snap-fit ​​component 5 are provided with multiple locking holes 19. The connecting plate 14 and the snap-fit ​​component 5 are fixedly connected by bolt assemblies that mate with the locking holes 19. Specifically, the snap-fit ​​component 5 and the locking holes 19 on the connecting plate 14 are aligned, and then the two are fixedly connected by bolt assemblies.

[0037] It also includes a power supply assembly 15, which is fixedly disposed within the housing 1 and electrically connected to the chip board 2 and the motor 12. The power supply assembly 15 is located inside the housing 1 on the side near the arc-shaped positioning plate 7, while the motor 12 and the reducer 13 are located on the other side inside the housing 1. Specifically, the power supply assembly 15 supplies power to the chip board 2 and the motor 12, and the arrangement of the power supply assembly 15 on both sides of the drive assembly ensures a balanced density inside the housing 1.

[0038] The chip board 2 is located above the motor 12, the reducer 13, and the power supply assembly 15. A cover plate 16 can also be detachably connected to the top of the housing 1. Specifically, the power supply assembly 15 and other electronic components such as the chip board 2 can be replaced by removing the cover plate 16.

[0039] The housing 1 is also fixedly provided with a power interface 17 that is electrically connected to the power supply assembly 15. Specifically, the power supply assembly 15 can be charged through the power interface 17, or the motor 12 can be directly powered.

[0040] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
