Description

Technical Field

[0001] This utility model relates to the field of fluid transport equipment technology, specifically to an adjustable electric switching valve with one inlet and two outlets. Background Technology

[0002] In fluid transport systems, electric valves are commonly used to control the delivery of fluids. Electric valves generally consist of a valve body, a motor, a valve core, and a valve seat. Current electric valves have only one outlet and can only control a single water circuit. When it is necessary to control the on / off state of two water circuits, two solenoid valves need to be installed. However, this method of adding extra solenoid valves makes the water circuit more complex, and the configuration cost of the water circuit system using electric valves also increases. Utility Model Content

[0003] The purpose of this utility model is to provide an adjustable electric switching valve with one inlet and two outlets. When controlling the on / off of two water circuits, there is no need to add an additional solenoid valve, which optimizes the water circuit structure and reduces the configuration cost of water circuit systems using electric valves. To solve the above-mentioned technical problems, the present invention adopts the following solution: An adjustable electric switching valve with one inlet and two outlets includes a valve seat, a valve cover, and a valve core. The valve core is movably disposed between the valve seat and the valve cover. The valve cover is provided with an inlet, a first outlet, and a second outlet. The valve core has a water passage cavity connected to the inlet. The side wall of the valve core is provided with a water passage channel connected to the water passage cavity, and the water passage area gradually changes along the circumference of the valve core. Rotation of the valve core controls the water passage channel to connect or block the water path between the inlet and the first and second outlets.

[0004] In this design, the valve seat serves as the basic support structure, providing an installation reference and a sealing base surface. The valve sleeve integrates an inlet, a first outlet, and a second outlet, which cooperate with the valve seat to form a fluid channel. The valve core is a movable part that achieves water circuit switching through rotation. The water passage chamber is connected to the inlet, and its side wall is provided with a water passage with a gradually changing water passage area. The water passage is connected to the water passage chamber, and the source water from the inlet enters the water passage chamber and then exits through the water passage. Initially, the valve core is in a position where the water passage is not aligned with either the first or second outlet. At this point, the water flow to both outlets is blocked. When water is needed from the first outlet, the valve core rotates until the water passage aligns with it, creating a passage between the inlet and the first outlet. Water enters the water chamber and water passage through the inlet and exits from the first outlet, while the second outlet remains blocked. When water is needed from the second outlet, the valve core rotates in the opposite direction until the water passage aligns with it. Water enters the water chamber through the inlet and exits from the second outlet, while the first outlet remains blocked. When neither outlet needs to output water, the valve core rotates to the misaligned position, closing both outlets. This solution allows the two outlets on a single electric valve to switch between outputs as needed through the rotation of the valve core. Furthermore, when the electric valve controls the flow of water through two channels, no additional solenoid valve is required, optimizing the water system structure and reducing the configuration cost of water systems using electric valves. Furthermore, due to the gradually changing water flow area of ​​the water passage, the rotation of the valve core results in different water flow areas connected to the outlet, which allows for the control and adjustment of the water output.

[0005] Optionally, the water passage includes a water inlet and a first water groove located on the side wall of the valve core. The water inlet is connected to the first water groove. The water passage area of ​​the first water groove gradually changes along the circumference of the valve core and is located on one side of the water inlet. The rotation of the valve core controls the water inlet to connect or block the water passage between the water inlet and the first and second water outlets.

[0006] Optionally, multiple water inlets are spaced apart along the valve core axis, and the depth of the first water inlet gradually changes along the circumference of the valve core.

[0007] Optionally, the end of the first water passage that connects to the water outlet has the greatest depth.

[0008] Optionally, the top surface of the valve seat is integrally formed with a sleeve, the inner cavity of the sleeve is adapted to the size of the valve core, the valve core is rotatably disposed in the inner cavity of the sleeve, the side wall of the sleeve is provided with a first mounting hole corresponding to the first water outlet and a second mounting hole corresponding to the second water outlet, a first sealing ring is embedded in the inner wall of the first mounting hole, a second sealing ring is embedded in the second mounting hole, the first sealing ring and the second sealing ring are in contact with the side wall of the valve core, the side wall of the sleeve is provided with a second water passage groove located between the first mounting hole and the second mounting hole, the second water passage groove is connected to the water inlet and the water passage cavity.

[0009] Optionally, a first support ring is provided inside the first sealing ring, and the first support ring has a first water passage hole in the middle that is connected to the first water outlet.

[0010] Optionally, a second support ring is provided inside the second sealing ring, and the second support ring has a second water passage hole in the middle that is connected to the second water outlet.

[0011] Optionally, the bottom wall of the water passage cavity is provided with a support cylinder that is adapted to and connected to the valve cover, a third sealing ring is provided between the support cylinder and the inner wall of the valve cover, and a fourth sealing ring is provided between the lower end of the valve core and the valve seat.

[0012] Optionally, a fifth sealing ring is provided between the sleeve and the inner wall of the valve cover.

[0013] Optionally, it also includes a drive motor, the output shaft of which passes through the valve seat and is connected to the lower end of the valve core, and the cross-section of the output shaft is waist-shaped.

[0014] The beneficial effects of this utility model are: In this utility model, the valve sleeve integrates an inlet, a first outlet, and a second outlet, which cooperate with the valve seat to form a fluid channel. The valve core is a movable part, and the water path is switched by rotation. The water passage is connected to the inlet, and its side wall is provided with a water passage with a gradually changing water passage area. The water passage is connected to the water passage, and the source water from the inlet enters the water passage and is then output through the water passage. Initially, the valve core is in a position where the water passage is not aligned with either the first or second outlet. At this point, the water flow to both outlets is blocked. When water is needed from the first outlet, the valve core rotates until the water passage aligns with it, creating a passage between the inlet and the first outlet. Water enters the water chamber and water passage through the inlet and exits from the first outlet, while the second outlet remains blocked. When water is needed from the second outlet, the valve core rotates in the opposite direction until the water passage aligns with it. Water enters the water chamber through the inlet and exits from the second outlet, while the first outlet remains blocked. When neither outlet needs to output water, the valve core rotates to the misaligned position, closing both outlets. This solution allows the two outlets on a single electric valve to switch between outputs as needed through the rotation of the valve core. Furthermore, when the electric valve controls the flow of water through two channels, no additional solenoid valve is required, optimizing the water system structure and reducing the configuration cost of water systems using electric valves. Furthermore, due to the gradually changing water flow area of ​​the water passage, the rotation of the valve core results in different water flow areas connected to the outlet, which allows for the control and adjustment of the water output.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0020] An adjustable electric switching valve with one inlet and two outlets includes a valve seat 05, a valve cover 08, and a valve core 03. The valve core 03 is movably disposed between the valve seat 05 and the valve cover 08. The valve cover 08 is provided with an inlet 18, a first outlet 09, and a second outlet 17. The valve core 03 has a water passage cavity 13 connected to the inlet 18 inside. The side wall of the valve core 03 is provided with a water passage channel connected to the water passage cavity 13, and the water passage area gradually changes along the circumference of the valve core 03. The rotation of the valve core 03 controls the water passage channel to connect or block the water path between the inlet 18 and the first outlet 09 and the second outlet 17.

[0021] In this embodiment, as Figure 1 , Figure 2 , Figure 3 As shown, valve seat 05 serves as the basic support structure, providing an installation reference and sealing base surface. The valve sleeve integrates inlet 18, first outlet 09, and second outlet 17, which cooperate with valve seat 05 to form a fluid channel. Valve core 03 is a movable part that achieves water circuit switching by rotation. Water passage chamber 13 is connected to inlet 18, and its side wall is provided with water passage with gradually changing water passage area. Water passage is connected to water passage chamber 13, and the source water from inlet 18 enters water passage chamber 13 and is then output through water passage. Initially, valve core 03 is in a position where the water passage is not aligned with the first outlet 09 and the second outlet 17. At this time, the water path of both outlets is blocked. When water needs to be discharged from the first outlet 09, valve core 03 rotates until the water passage is aligned with the first outlet 09, forming a passage between the inlet 18 and the first outlet 09. The source water enters the water passage chamber 13 through the water passage from the inlet 18 and is discharged from the first outlet 09. At this time, the second outlet 17 is still blocked. When water needs to be discharged from the second outlet 17, valve core 03 rotates in the opposite direction until the water passage is aligned with the second outlet 17. The source water enters the water passage chamber 13 through the inlet 18 and is discharged from the second outlet 17. At this time, the first outlet 09 is blocked. When neither outlet needs to discharge water, valve core 03 rotates to a non-aligned position, and both outlets are closed. This solution utilizes the rotation of valve core 03 to allow the two outlets on an electric valve to switch water flow as needed. Furthermore, when the electric valve controls the flow of water through two channels, no additional solenoid valve is required, optimizing the water circuit structure and reducing the configuration cost of the water system using the electric valve. Moreover, due to the gradually changing flow area of ​​the water passage, the rotation of valve core 03 results in different flow areas connected to the outlets, thus enabling control and adjustment of the water flow rate.

[0022] Furthermore, the water passage includes a water inlet 21 and a first water groove 20 located on the side wall of the valve core 03. The water inlet 21 is connected to the first water groove 20. The water passage area of ​​the first water groove 20 gradually changes along the circumference of the valve core 03 and is located on one side of the water inlet 21. The rotation of the valve core 03 controls the water inlet 21 to connect or block the water passage between the inlet 18 and the first outlet 09 and the second outlet 17.

[0023] Furthermore, multiple water inlets 21 are spaced apart along the axial direction of the valve core 03, and the depth of the first water inlet 20 gradually changes along the circumference of the valve core 03.

[0024] Furthermore, the end of the first water passage 20 that connects to the water outlet 21 has the greatest depth.

[0025] Specifically, such as Figure 2 and Figure 3 As shown, the first water passage trough 20 is a strip-shaped groove with a certain depth, but it does not penetrate the side wall of the valve core 03 radially upwards. Multiple first water passage troughs 20 can be provided, with the end of the first water passage 20 connected to the water outlet 21 having the greatest depth. Figure 2 As shown, if valve core 03 does not rotate, the water paths of both outlets are blocked. If valve core 03 rotates clockwise, the water inlet 21 first connects to the second outlet 17. At this time, the water path between the inlet 18 and the second outlet 17 is connected, and the source water enters the water passage chamber 13 through the inlet 18 and is then transported to the second outlet 17 through the water inlet 21. If valve core 03 continues to rotate clockwise, the water passage area between the first water passage trough 20 and the second outlet 17 gradually decreases, and the water output gradually decreases. Conversely, if valve core 03 rotates counterclockwise, the end of the first water passage trough 20 furthest from the water inlet 21 first connects to the first outlet 09, which is also the position with the smallest water passage area of ​​the first water passage trough 20. At this time, the output flow rate is the smallest. If valve core 03 continues to rotate counterclockwise, the water passage area connected to the second outlet 17 gradually increases, and the output flow rate also gradually increases.

[0026] It should be noted that the valve core 03 can be rotated either clockwise or counterclockwise to adjust the water flow from the first outlet 09 and the second outlet 17. Alternatively, water can flow from the second outlet 17 when rotated clockwise and from the first outlet 09 when rotated counterclockwise.

[0027] Furthermore, the top surface of the valve seat 05 is integrally formed with a sleeve 24. The inner cavity of the sleeve 24 is adapted to the size of the valve core 03. The valve core 03 is rotatably disposed in the inner cavity of the sleeve 24. The side wall of the sleeve 24 is provided with a first mounting hole 23 corresponding to the first water outlet 09 and a second mounting hole 22 corresponding to the second water outlet 17. A first sealing ring 07 is embedded in the inner wall of the first mounting hole 23, and a second sealing ring 14 is embedded in the second mounting hole 22. The first sealing ring 07 and the second sealing ring 14 are in contact with the side wall of the valve core 03. The side wall of the sleeve 24 is provided with a second water passage groove 19 located between the first mounting hole 23 and the second mounting hole 22. The second water passage groove 19 is connected to the water inlet 18 and the water passage cavity 13.

[0028] Furthermore, a first support ring 11 is provided on the inner side of the first sealing ring 07, and the first support ring 11 has a first water passage hole 10 in the middle that is connected to the first water outlet 09.

[0029] Furthermore, a second support ring 15 is provided on the inner side of the second sealing ring 14, and the second support ring 15 has a second water passage hole 16 in the middle that is connected to the second water outlet 17.

[0030] Specifically, such as Figure 3 As shown, the sleeve 24 is vertically mounted on the top surface of the valve seat 05. The sleeve 24 and the valve seat 05 are integrally formed. The sleeve 24 has an internal cavity that matches the size of the valve core 03. The valve core 03 is rotatably mounted in this internal cavity. Opposite first mounting holes 23 and second mounting holes 22 are provided on the side wall of the sleeve 24. A matching first sealing ring 07 is installed in the first mounting hole 23, and a first support ring 11 for supporting the first sealing ring 07 is provided inside the first sealing ring 07. A matching second sealing ring 14 is installed in the second mounting hole 22, and a first support ring 11 for supporting the first sealing ring 07 is provided inside the second mounting hole 22. The second support ring 15 supports the second sealing ring 14. The first support ring 11 can support the first sealing ring 07 to prevent the first sealing ring 07 from collapsing. The second support ring 15 can support the second sealing ring 14 to prevent the second sealing ring 14 from collapsing. The sides of the first sealing ring 07 and the second sealing ring 14 are in contact with the side wall of the water passage of the valve core 03. In this way, when the water outlet 21 is not connected to the first water outlet 09 and the second water outlet 17, the gap between the valve core 03 and the sleeve 24 can be sealed. The first water passage hole 10 in the middle of the first support ring 11 is connected to the first water outlet 09, and the second water passage hole 16 in the middle of the second support ring 15 is connected to the second water outlet 17. When the water passage 21 is connected to the first water passage hole 10, the source water can be transported to the first water outlet 09. Similarly, when the water passage 21 is connected to the second water passage hole 16, the source water can be transported to the second water outlet 17. The source water enters the water passage cavity 13 from the water inlet 18 through the second water passage groove 19. Furthermore, the bottom wall of the water passage cavity 13 is provided with a support cylinder 25 that is adapted to and connected to the valve cover 08. A third sealing ring 12 is provided between the support cylinder 25 and the inner wall of the valve cover 08, and a fourth sealing ring 04 is provided between the lower end of the valve core 03 and the valve seat 05.

[0031] Specifically, such as Figure 1 As shown, the third sealing ring 12 is pressed between the inner top wall of the valve cover 08 and the support cylinder 25 to seal the gap between the support cylinder 25 and the inner wall of the valve cover 08. The support cylinder 25 and the inner top wall of the valve cover 08 are interlocked. The support cylinder 25 can improve the smoothness of the rotation of the valve core 03 and prevent it from swinging. The fourth sealing ring 04 is used to seal the installation gap between the lower end of the valve core 03 and the valve seat 05 to prevent water from entering the drive motor 01 below.

[0032] Furthermore, a fifth sealing ring 06 is provided between the sleeve 24 and the inner wall of the valve cover 08. Specifically, the fifth sealing ring 06 is embedded in the side wall of the sleeve 24, and the fifth sealing ring 06 is used to seal the installation gap between the valve cover 08 and the sleeve 24 to prevent water leakage.

[0033] Furthermore, it also includes a drive motor 01, the output shaft 02 of the drive motor 01 passes through the valve seat 05 and is connected to the lower end of the valve core 03, and the cross section of the output shaft 02 is waist-shaped.

[0034] Specifically, such as Figure 3 As shown, the output shaft 02 is waist-shaped, which is a conventional setting. Specifically, from the cross-section, the two opposite sides of the output shaft 02 are flat, and the other two opposite sides are curved. The drive motor 01 drives the output shaft 02 to rotate, which in turn drives the valve core 03 to rotate, thereby controlling the two water outlet channels. The drive motor 01 and the valve seat 05 are fixed together by bolts.

[0035] 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.
