Abstract
Description
Technical Field
[0001] This application relates to the field of control valve technology, and more specifically to a built-in control valve system for radiator devices. Background Technology
[0002] In traditional heating systems, control valves are typically designed as external components, installed outside the radiators to regulate the heat output of each radiator group. This structure originates from early heating system designs aimed at facilitating manual operation and maintenance by users. However, in modern residential and commercial buildings, this design often presents some inconveniences.
[0003] First, external control valves occupy valuable interior space, especially in compact environments, potentially limiting furniture placement and flexibility in interior layout. Second, the appearance of such external valves may clash with modern interior design styles, affecting the overall aesthetics.
[0004] Another challenge with external control valves lies in their high precision requirements. Because heat regulation demands precise control, external valves need excellent sealing and a sensitive operating mechanism to ensure users can effectively adjust indoor temperatures. However, external environmental factors, such as temperature variations, dust, and mechanical wear, can affect valve performance, leading to reduced control accuracy and impacting comfort and energy efficiency. Utility Model Content
[0005] Therefore, this application provides a built-in control valve system for radiator devices to solve the problems of space occupation, unsightly appearance, and reduced accuracy due to external environmental factors in the prior art.
[0006] To achieve the above objectives, this application provides the following technical solution:
[0007] A built-in control valve is disclosed. The radiator device includes a first radiator and a second radiator sequentially from one end to the other. Both the first and second radiators have horizontal partitions inside, which divide the cavities within the first and second radiators into an upper water chamber and a lower water chamber. A water inlet pipe is connected to the bottom of the first radiator and communicates with the lower water chamber of the first radiator. A drain pipe is connected to the bottom of the second radiator and communicates with the lower water chamber of the second radiator.
[0008] The first and second radiators are equipped with valve bodies, which are inserted through the partition and partially located in the upper water chamber and the other part in the lower water chamber. A valve core is coaxially arranged inside the valve body and can rotate inside the valve body.
[0009] The valve body has an inlet, a first outlet, a second outlet, and a third outlet on its peripheral wall. The line connecting the inlet and the third outlet, and the line connecting the first outlet and the second outlet, are parallel to the axis of the valve body. The valve core has a first through hole and a second through hole spaced apart along its own axial direction on its peripheral wall. The inlet and the first outlet are respectively connected to the lower water chamber and the upper water chamber of the first radiator, and the second outlet and the third outlet are respectively connected to the upper water chamber and the lower water chamber of the second radiator. When the valve core rotates, the first through hole can intermittently connect with the first outlet, and the second through hole can intermittently connect with the second outlet and the third outlet.
[0010] Optionally, multiple inlets, first outlets, second outlets, third outlets, first through holes, and second through holes are provided, and their number and distribution positions are corresponding; during the rotation of the valve core, the first through holes and the first outlets can be aligned one by one, and the second through holes can be aligned one by one with the second outlets and the third outlets respectively, and when the first through hole is aligned with the first outlet, the second through hole is aligned with the second outlet.
[0011] Optionally, the end of the valve core near the second radiator is a semi-cylindrical structure, and the second through hole is opened on the cylindrical surface of the semi-cylindrical structure.
[0012] Optionally, the inlet and the first outlet are offset in the axial direction of the valve body; the length of the valve core is less than the length of the inner cavity of the valve body, the front end of the valve core is open, and the inlet is located between the front end face of the valve core and the front end face of the inner cavity of the valve body.
[0013] Optionally, the rear end face of the valve core abuts against the rear end face of the valve body cavity.
[0014] Optionally, the radiator device further includes a third radiator located behind the second radiator; the rear end of the valve body is provided with a drain port, the rear end of the drain port is connected to the interior of the third radiator, and the front end is connected to the interior of the valve body.
[0015] Optionally, the radiator device further includes a tail radiator, the bottom of which is connected to a connecting pipe, which is connected to a drain pipe.
[0016] Optionally, a connecting rod is fixedly connected to the valve core. The connecting rod passes through the front end of the valve body and the first radiator, and is rotatably connected to the valve body and the first radiator. A rotating handle is fixed to one end of the connecting rod that extends out of the first radiator.
[0017] Optionally, a bearing is provided at the connection position between the connecting rod and the valve body and the first radiator.
[0018] Optionally, a sealing ring is provided between the valve body and the first radiator and the second radiator respectively.
[0019] Compared with the prior art, this application has at least the following beneficial effects:
[0020] 1. The valve body is embedded inside the radiator unit, reducing the space occupied by the entire control valve and improving the overall aesthetics. Furthermore, the control valve is easy to operate; the opening degree of the heating system is adjusted by rotating the valve core to regulate the fit between the first and second through holes and the first, second, and third water outlets. Because the control valve is built-in, it is less affected by external environmental factors, resulting in a longer lifespan and less susceptibility to control accuracy.
[0021] 2. By setting multiple inlets, first outlets, second outlets, third outlets, first through holes, and second through holes, the number of holes can be adjusted when the valve core is rotated, thus making it easier to control the heating opening. Attached Figure Description

Expressions such as "comprising," "including," and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).
[0035] The terms used in this application, such as "upper," "lower," "left," "right," and "middle," are generally used to indicate the general relative positional relationship for the purpose of intuitive understanding by referring to the accompanying drawings, and are not absolute limitations on the positional relationship in the actual product.
[0036] An integrated control valve system for radiator installations, as described above. Figure 1 The heating radiator assembly includes, from one end (water inlet) to the other end (water outlet), a first heating radiator 1, a second heating radiator 2, a third heating radiator 3, and so on, with the last end being the tail heating radiator 4.
[0037] Reference Figures 1-8 The first radiator 1 and the second radiator 2 are both fixedly equipped with horizontal partitions 5. The partitions 5 divide the cavities at the bottom of the first radiator 1 and the second radiator 2 into an upper water cavity 6 and a lower water cavity 7. The lower water cavity 7 is below the upper water cavity 6.
[0038] The bottom of the first radiator 1 is connected to a water inlet pipe 8, which is connected to the drain chamber 7 of the first radiator 1. The bottom of the second radiator 2 is connected to a drain pipe 9, which is connected to the drain chamber 7 of the second radiator 2.
[0039] The first radiator 1 and the second radiator 2 are embedded with the same valve body 10. The valve body 10 is a cylindrical structure and is located in the middle of the partition 5. Part of the valve body 10 is located in the upper water chamber 6, and the other part is located in the lower water chamber 7. A cylindrical valve core 11 is coaxially arranged inside the valve body 10, and the valve core 11 can rotate freely within the valve body 10.
[0040] Specifically, the length of the valve core 11 is less than the length of the inner cavity of the valve body 10, and the rear end face of the valve core 11 abuts against the rear end face of the inner cavity of the valve body 10, so that there is a certain gap between the front end face of the valve core 11 and the front end face of the inner cavity of the valve body 10.
[0041] To connect the water in the upper water chamber 6 and the lower water chamber 7, an inlet 12, a first outlet 13, a second outlet 14, and a third outlet 15 are provided on the peripheral wall of the valve body 10. The lines connecting the inlet 12 and the third outlet 15, and the lines connecting the first outlet 13 and the second outlet 14, are parallel to the axis of the valve body 10, i.e., located on two generatrices of the valve body 10. A first through hole 16 and a second through hole 17 are provided on the peripheral wall of the valve core 11 along its axial direction from front to back.
[0042] Specifically, the inlet 12 and the first outlet 13 are connected to the lower water chamber 7 and the upper water chamber 6 of the first radiator 1, respectively, and the second outlet 14 and the third outlet 15 are connected to the upper water chamber 6 and the lower water chamber 7 of the second radiator 2, respectively. When the valve core 11 rotates, the first through hole 16 can intermittently connect with the first outlet 13, and the second through hole 17 can intermittently connect with the second outlet 14 and the third outlet 15. Furthermore, since the first outlet 13 and the second outlet 14 are located on the same generatrix of the valve body 10, the second through hole 17 connects with the second outlet 14 while the first through hole 16 is connected with the first outlet 13.
[0043] In this embodiment, the front end face of the valve core 11 is open, and the inlet 12 is located between the front end face of the valve core 11 and the front end face of the inner cavity of the valve body 10, so that the first through hole 16 and the first outlet 13 are always axially offset from the inlet 12. Therefore, no matter where the valve core 11 is rotated, the water from the inlet pipe 8 can always enter the lower water chamber 7 of the first radiator 1, then enter the interior of the valve body 10 through the inlet 12, and finally enter the interior of the valve core 11 through the opening on the front end face of the valve core 11.
[0044] When closed, valve core 11 rotates to the position where the second through hole 17 connects with the third outlet 15. Water inside valve body 10 flows directly through the second through hole 17 and the third outlet 15 into the lower water chamber 7 of the second radiator 2, and is then discharged through drain pipe 9. When valve core 11 is rotated to the open position, the first through hole 16 is partially or fully connected to the first outlet 13, and the second through hole 17 is also moved away from the third outlet 15 (at this time, the third outlet 15 is in a blocked state) and partially or fully connected to the second outlet 14. Then, part of the water inside valve body 10 flows into the first radiator 1 through inlet 12 and first outlet 13, and the other part flows into the second radiator 2 through the second through hole 17 and second outlet 14, thus providing heating to the radiator device. The degree of connection between the first through hole 16 and the second through hole 17 and the corresponding outlet is adjusted by rotating valve core 11, thereby adjusting the opening degree of the heating.
[0045] In this embodiment, the rear half of the valve core 11 (i.e., the position near the second radiator 2) is a semi-cylindrical structure, and the rear end of the planar portion is chamfered, so that there is always a certain space between the planar portion of the rear half of the valve core 11 and the inner wall of the valve body 10. At this time, the second through hole 17 is opened on the cylindrical surface of the semi-cylindrical structure, and during the rotation of the valve core 11, the planar portion of the semi-cylindrical structure is always away from the inner wall of the valve body 10.
[0046] Correspondingly, a drain port 18 is provided at the rear end of the valve body 10. The rear end of the drain port 18 is connected to the interior of the third radiator 3, and the front end is connected to the interior of the valve body 10, that is, it is connected to the space formed between the semi-cylindrical structure of the rear half of the valve core 11 and the inner wall of the valve body 10. Thus, when the valve core 11 rotates to a position where the cylindrical surface of the semi-cylindrical structure is away from the third outlet 15, the third outlet 15 is located in the space between the flat part of the semi-cylindrical structure and the inner wall of the valve body 10. At this time, the third radiator 3, the drain port 18, the third outlet 15, the lower water chamber 7 of the second radiator 2, and the drain pipe 9 are in a state of interconnection, so some of the water inside the radiator device can be discharged through the drain pipe 9.
[0047] Furthermore, when the total number of radiators in the heating system exceeds 12, a connecting pipe 19 is added to the bottom of the radiator 4 at the rear end, and the connecting pipe 19 is connected to the drain pipe 9. Then, another part of the water inside the heating system can be discharged through the drain pipe 9 via the connecting pipe 19.
[0048] To facilitate adjustment of the heating opening, multiple inlet 12, first outlet 13, second outlet 14, third outlet 15, first through hole 16, and second through hole 17 are provided, and their number and distribution positions are corresponding. In this embodiment, three of each are provided, and they are evenly spaced along the circumference. During the rotation of the valve core 11, the three first through holes 16 can be aligned with the three first outlets 13 one by one, and the three second through holes 17 can be aligned with the three second outlets 14 and the three third outlets 15 one by one, respectively. When the first through hole 16 is aligned with the first outlet 13, the second through hole 17 is aligned with the second outlet 14.
[0049] To facilitate the rotation of the valve core 11, a horizontal connecting rod 20 is fixedly connected to the valve core 11. The front end of the connecting rod 20 passes through the front end of the valve body 10 and the first radiator 1, and is rotatably connected to the valve body 10 and the first radiator 1. A rotating handle 22 is fixed to the front end of the connecting rod 20. To improve the smoothness of the rotation of the connecting rod 20, bearings are provided at the connection points between the connecting rod 20 and the valve body 10 and the first radiator 1.
[0050] To improve sealing, sealing rings 21 are provided between the valve body 10 and the first radiator 1 and the second radiator 2, respectively.
[0051] The implementation principle of this application embodiment is as follows: ① Valve core 11 closed: Rotate valve core 11 to align and connect the second through hole 17 with the third outlet 15 one by one. The second outlet 14 and the first outlet 13 are both in a blocked state. At this time, the water in the inlet pipe 8 passes through the inlet 12, the lower water chamber 7 of the first radiator 1, the inside of the valve body 10, the inside of the valve core 11, the second through hole 17, the third outlet 15, the lower water chamber 7 of the second radiator 2, and finally is discharged through the drain pipe 9.
[0052] ② Fully open valve core 11: Rotate valve core 11 so that the first through hole 16 aligns with the first outlet 13, and the second through hole 17 aligns with the second outlet 14. At this time, the flat part of the semi-cylindrical structure at the rear end of valve core 11 faces the third outlet 15. Water from inlet pipe 8 flows sequentially through inlet 12, the lower water chamber 7 of the first radiator 1, the inside of valve body 10, and the inside of valve core 11. Part of the water enters the first radiator 1 through the first through hole 16 and the first outlet 13, while the other part enters the second radiator 2 through the second through hole 17 and the second outlet 14. The water circulates within the radiator device, providing maximum heating. Part of the water enters the drain port 18 of the valve body 10 through the third radiator 3, then flows through the space between the semi-cylindrical structure of the valve core 11 and the inner wall of the valve body 10, through the third outlet 15, and finally is discharged through the drain pipe 9; the other part of the water flows through the tail radiator 4 through the connecting pipe 19 to the drain pipe 9 and is discharged.
[0053] ③ Valve core 11 half open: Rotate valve core 11 to align the first through hole 16 with the first outlet 13 and the second through hole 17 with the second outlet 14. The water flow path is the same as when valve core 11 is fully open, except that the water flow into the radiator is reduced, that is, the opening degree of the radiator is reduced.
[0054] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
