Description

Technical Field

[0001] This utility model relates to the field of fluid transport equipment technology, specifically to an electric mixing valve with two inlets and one outlet. Background Technology

[0002] In fluid transport systems, electric valves are commonly used to control the delivery of fluids. An electric valve generally consists of a valve body, a motor, a valve core, and a valve seat. Currently, electric valves only have one inlet and one outlet, and can only supply water to a single water circuit. When it is necessary to supply hot water and cold water to downstream equipment separately, two electric valves need to be installed. However, this method of adding extra electric valves will make the water circuit more complex, and the configuration cost of the water circuit system using electric valves will also increase. Utility Model Content

[0003] The purpose of this utility model is to provide a two-inlet, one-outlet electric mixing valve, which eliminates the need for additional electric valves when supplying water to the equipment via two channels, thus optimizing the water circuit structure and reducing the configuration cost of water circuit systems using electric valves.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following solution: An electric mixing valve with two inlets and one outlet includes a valve seat, a valve body, and a valve core movably disposed between the valve seat and the valve body. The valve body is provided with a first inlet, a second inlet, and an outlet. The valve core is provided with a water passage chamber connected to the outlet. Rotation of the valve core controls the first inlet and the second inlet to supply water to the water passage chamber separately or simultaneously.

[0005] In this design, the valve housing has three openings: a first inlet, a second inlet, and an outlet. The valve core is a rotatable moving part, with its internal water passage chamber connected to the outlet. During the rotation of the valve core, the water passage chamber selectively connects to the first inlet and / or the second inlet.

[0006] Cold and hot water enter the valve body through the first inlet and the second inlet, respectively, and then enter the water passage chamber. Initially, the water passage chamber is connected to both the first and second inlets, or it can be that the water passage chamber is not connected to either the first or the second inlet in the initial state.

[0007] When the control system (such as a thermostat) issues a command, it drives a motor to rotate the valve core. The rotation of the valve core changes the relative position of its openings to the two inlets on the valve body. When the valve core rotates to a certain angle, the first inlet (cold water) connects to the water passage chamber, while the water passage between the second inlet (hot water) and the water passage chamber is blocked. At this time, cold water is output from the outlet. When the valve core rotates to another angle, the second inlet (hot water) connects to the water passage chamber, while the water passage between the first inlet (cold water) and the water passage chamber is blocked. At this time, hot water is output from the outlet. When the valve core is positioned such that both the first and second inlets are connected to the water passage chamber, cold and hot water simultaneously enter the water passage chamber and mix. The mixed water is then output from the outlet, resulting in consistently warm water. This solution achieves two water supply paths with a single electric valve, eliminating the need for additional electric valves, optimizing the water circuit structure, and reducing the configuration cost of water systems using electric valves.

[0008] Optionally, the valve core sidewall is provided with a water inlet that connects to the water passage cavity. The water inlet is arranged along the circumference of the valve core, and multiple water inlets are distributed along the valve core axis. The valve core sidewall area between the two ends of the water inlet is a sealing surface. When the valve core rotates to the point where the sealing surface corresponds to the first water inlet or the second water inlet, the water passage between the first water inlet and / or the second water inlet and the water passage cavity is blocked.

[0014] Optionally, the first inlet and the second inlet are located on one side of the outlet, and the first inlet and the second inlet are perpendicular to the outlet. The lines connecting the two ends of the inlet to the center of the valve core form a V shape.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0023] An electric mixing valve with two inlets and one outlet includes a valve seat 04, a valve housing 07, and a valve core 06 movably disposed between the valve seat 04 and the valve housing 07. The valve housing 07 is provided with a first inlet 11, a second inlet 14, and an outlet 12. The valve core 06 is provided with a water passage chamber 18 that communicates with the outlet 12. The rotation of the valve core 06 controls the first inlet 11 and the second inlet 14 to supply water to the water passage chamber 18, either separately or simultaneously.

[0024] In this embodiment, as Figure 1 , Figure 2 , Figure 3 As shown, the valve housing 07 has three openings: a first inlet 11, a second inlet 14, and an outlet 12. The valve core 06 is a rotatable movable part, and its internal water passage chamber 18 is connected to the outlet 12. During the rotation of the valve core 06, the water passage chamber 18 selectively connects to the first inlet 11 and / or the second inlet 14.

[0025] Taking the first inlet 11 as the cold water inlet and the second inlet 14 as the hot water inlet as an example, the cold and hot water enter the valve body 07 from the first inlet 11 and the second inlet 14 respectively, and then enter the water passage chamber 18. That is, in the initial state, the water passage chamber 18 is connected to both the first inlet 11 and the second inlet 14. Of course, in the initial state, the water passage chamber 18 is not connected to either the first inlet 11 or the second inlet 14.

[0026] When the control system (such as a thermostat) issues a command, it drives a drive motor 01 to rotate the valve core 06. The rotation of the valve core 06 changes the relative position of its opening and the two inlets on the valve housing 07. When the valve core 06 rotates to a certain angle, the first inlet 11 (cold water) is connected to the water passage chamber 18, and the water passage between the second inlet 14 (hot water) and the water passage chamber 18 is blocked. At this time, the outlet 12 outputs cold water. When the valve core 06 rotates to another angle, the second inlet 14 (hot water) is connected to the water passage chamber 18, and the water passage between the first inlet 11 (cold water) and the water passage chamber 18 is blocked. At this time, the outlet 12 outputs hot water. When the valve core 06 is positioned such that both the first inlet 11 and the second inlet 14 are connected to the water passage chamber 18, cold water and hot water simultaneously enter the water passage chamber 18 and mix. The mixed water is output from the outlet 12, thus obtaining warm water at a constant temperature. This solution enables dual water supply through a single electric valve, eliminating the need for additional electric valves, thus optimizing the water circuit structure and reducing the configuration cost of water systems using electric valves.

[0027] Furthermore, the valve core 06 has a water inlet 13 on its side wall that connects to the water passage cavity 18. The water inlet 13 is arranged circumferentially along the valve core 06, and multiple water inlets 13 are distributed along the axis of the valve core 06. The area of ​​the side wall of the valve core 06 between the two ends of the water inlet 13 is a sealing surface 21. When the valve core 06 rotates to the point where the sealing surface 21 corresponds to the first water inlet 11 or the second water inlet 14, the water passage between the first water inlet 11 or the second water inlet 14 and the water passage cavity 18 is blocked.

[0028] Specifically, such as Figure 2 As shown, the valve core 06 is a cylindrical structure. The center of the valve core 06 is a water passage cavity 18, open at the top and closed at the bottom. The side wall of the valve core 06 has circumferentially arranged water passage ports 13 that communicate with the water passage cavity 18. These water passage ports 13 are arc-shaped and multiple are distributed along the axis of the valve core 06 to increase the water flow. The two ends of the water passage ports 13 are not connected. The area on the side wall of the valve core 06 between the two ends of the water passage ports 13 is a sealing surface 21. When the valve core 06 rotates until the sealing surface 21 corresponds to the first water inlet 11, the first water inlet 11 and the water passage cavity 18... The water path between them is blocked. Similarly, when rotated to correspond with the second inlet 14, the water path between the second inlet 14 and the water passage 18 is blocked. Only when the water passage 13 is rotated to correspond with the first inlet 11 or the second inlet 14 can the first inlet 11 or the second inlet 14 be connected to the water passage 18. In this way, by controlling the rotation angle of the valve core 06, two water supply lines can be controlled by one electric valve. It can supply hot water, cold water, or mixed water separately, which reduces the number of electric valves used in the system and optimizes the water path structure.

[0029] Furthermore, a valve sleeve 22 connected to the top surface of the valve seat 04 is fitted on the outer side of the valve core 06. The lower end of the valve core 06 is rotatably connected to the valve seat 04. A first sealing ring 03 is fitted on the lower end of the valve core 06. The first sealing ring 03 is pressed between the valve core 06 and the valve seat 04. A second sealing ring 05 is fitted on the lower end of the valve sleeve 22. The second sealing ring 05 is pressed between the valve sleeve 22 and the valve body 07.

[0030] Specifically, such as Figure 3 As shown, a valve sleeve 22 is integrally formed on the top surface of the valve seat 04. The size of the valve sleeve 22 is adapted to the valve core 06. The valve core 06 is fitted inside the valve sleeve 22. The lower end of the valve core 06 is rotatably connected to the valve seat 04. The valve sleeve 22 can stabilize the rotation of the valve core 06. The first sealing ring 03 is embedded in the groove at the lower end of the valve core 06 to seal the rotation gap between the valve core 06 and the valve seat 04. The second sealing ring 05 is embedded in the groove at the lower end of the valve sleeve 22 to seal the installation gap between the valve body 07 and the valve sleeve 22 to prevent water leakage.

[0031] Furthermore, the valve housing 07 is provided with a vertically upward-facing outlet 12 at the top, and the first inlet 11 and the second inlet 14 are provided on the side wall of the valve housing 07.

[0032] Specifically, such as Figure 3 As shown, the outlet 12 is vertically positioned at the center of the top of the valve housing 07, while the first inlet 11 and the second inlet 14 are distributed on the side wall of the valve housing 07. The outlet 12, the first inlet 11, and the second inlet 14 are all tubular.

[0033] Furthermore, the first inlet 11 and the second inlet 14 are distributed on both sides of the outlet 12. The first inlet 11 and the second inlet 14 are parallel to the outlet 12. The first inlet 11, the second inlet 14 and the two ends of the water passage 13 are all located in the diameter direction of the valve core 06.

[0034] Furthermore, the valve sleeve 22 has a first mounting hole 20 corresponding to the first water inlet 11 and a second mounting hole 19 corresponding to the second water inlet 14 on its side wall.

[0035] Furthermore, a first sealing ring 08 is embedded in the first mounting hole 20, and a first support ring 09 is provided inside the first sealing ring 08 to support the first sealing ring 08. The first support ring 09 has a first water passage hole 10 in the middle that connects to the first water inlet 11. A second sealing ring 17 is embedded in the second mounting hole 19, and a second support ring 16 is provided inside the second sealing ring 17 to support the second sealing ring 17. The second support ring 16 has a second water passage hole 15 in the middle that connects to the second water inlet 14. The center line connecting the first water passage hole 10 and the second water passage hole 15 is located on the diameter of the valve core 06.

[0036] This embodiment describes one arrangement of the water inlet, the first water outlet 12, and the second water outlet 12. Specifically, as follows: Figure 4 , Figure 5 , Figure 6As shown, the first inlet 11 and the second inlet 14 are vertically distributed on both sides of the valve body 07, symmetrically distributed with the inlet axis as the center line. The first inlet 11 and the second inlet 14 are parallel to the outlet 12. The two ends of the through-port 13 are located on the diameter of the valve core 06, that is, the arc length of the through-port 13 is basically the same as the arc length of the sealing surface 21. When the through-port 13 is simultaneously connected to the first inlet 11 and the second inlet 14, that is, when the first through-hole 10 is connected to the through-port 13 and the second through-hole 15 is connected to the through-port 13, the first inlet 11 and the second inlet 14 are connected to the valve body 07. The two ends of the two inlets 14, the first water passage 10, the second water passage 15, and the water passage 13 are on the same diameter. At this time, mixed water can be delivered to the outlet 12 and then output from the outlet 12. When the valve core 06 rotates to the point where the sealing surface 21 is aligned with the first water passage 10 or the second water passage 15, the water passage 13 is connected to the first water passage 10 or the second water passage 15. Only the first inlet 11 delivers cold water to the water passage chamber 18 or only the second inlet 14 delivers hot water to the water passage chamber 18. The outlet 12 can only output cold water or hot water.

[0037] Furthermore, the first inlet 11 and the second inlet 14 are distributed on one side of the outlet 12, and the first inlet 11 and the second inlet 14 are perpendicular to the outlet 12. The two ends of the water inlet 13 are connected to the center of the valve core 06 in a V shape.

[0038] Furthermore, the valve sleeve 22 has a third mounting hole 25 corresponding to the first inlet 11, a fourth mounting hole 23 corresponding to the second inlet 14, and a fifth mounting hole 24 on its side wall. A third sealing ring 28 is embedded in the third mounting hole 25, and a third support ring 27 for supporting the third sealing ring 28 is provided inside the third sealing ring 28. The third support ring 27 has a third water passage hole 26 in the middle that connects to the first inlet 11. A fourth sealing ring 31 is embedded in the fourth mounting hole 23. The inner side of the rubber ring 31 is provided with a fourth support ring 30 for supporting the fourth sealing rubber ring 31. The fourth support ring 30 has a fourth water passage hole 29 in the middle that connects to the second water inlet 14. The fifth sealing rubber ring 34 is embedded in the fifth mounting hole 24. The inner side of the fifth sealing rubber ring 34 is provided with a fifth support ring 33 for supporting the fifth sealing rubber ring 34. The fifth support ring 33 has a fifth water passage hole 32 in the middle. The line connecting the third water passage hole 26, the fourth water passage hole 29, the fifth water passage hole 32 and the center of the valve core 06 cross section forms a Y shape.

[0039] This embodiment presents another distribution of the first inlet 11 and the second inlet 14. Specifically, the first inlet 11 and the second inlet 14 are horizontally distributed on one side of the valve housing 07, parallel and symmetrically distributed. The first inlet 11 and the second inlet 14 are perpendicular to the outlet 12, and the distance between the two inlets is small. The line connecting the third through hole 26, the fourth through hole 29 and the center of the valve core 06 cross section forms a V-shape, and the cross section is a cross section perpendicular to the axis of the valve core 06. The lengths at both ends of the through hole 13 are less than the diameter of the valve core 06 cross section. The third sealing ring 28, the fourth sealing ring 31, and the fifth sealing ring 34 seal the space between the valve core 06 and the valve sleeve 22. The rotation gap also provides three-point support for the valve core 06. When the valve core 06 rotates to the point where the third water passage 26 and the fourth water passage 29 are connected to the water passage 13, the first water inlet 11 and the second water inlet 14 can simultaneously supply water to the water passage chamber 18, and the outlet 12 can output mixed water. After the valve core 06 rotates clockwise by a certain angle, the sealing surface 21 blocks the third water passage 26. At this time, the water passage 13 is connected to the fourth water passage 29, and the second water inlet 14 can supply hot water to the water passage chamber 18. Conversely, after rotating counterclockwise by a certain angle, the sealing surface 21 blocks the fourth water passage 29. At this time, the water passage 13 is connected to the first water inlet 11, and the first water inlet 11 can supply cold water to the water passage chamber 18.

[0040] Furthermore, a drive motor 01 is provided at the lower end of the valve seat 04, and the output shaft 02 of the drive motor 01 passes upward through the valve seat 04 and connects to the lower end of the valve core 06.

[0041] Specifically, such as Figure 1 and 4 As shown, the drive motor 01 is bolted to the bottom of the valve seat 04. The output shaft 02 of the drive motor 01 passes upward through the valve seat 04 and is connected to the lower end of the valve core 06. The cross-section of the output shaft 02 is waist-shaped, which can prevent the output shaft 02 from rotating relative to the lower end of the valve core 06.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of the present utility model and within the spirit and principles of the present utility model shall still fall within the protection scope of the present utility model.
