Description

Technical Field

[0001] This utility model relates to the field of fluid transport equipment technology, specifically to an electric switching valve with dual water 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 electric switching valve with dual water outlets. When controlling the on / off of the two water outlets, there is no need to add an additional solenoid valve, which optimizes the water outlet structure, reduces the configuration cost of the water outlet system using electric valves, and can also control and adjust the water output.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following solution: An electric switching valve with dual water 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 groove one and a water passage groove two connected to the water passage cavity, and the water passage area gradually changes along the circumference of the valve core. The water passage groove one and the water passage groove two are symmetrically arranged. The rotation of the valve core controls the connection or blockage of the water passage between the inlet and the first and second outlets.

[0005] 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. The side wall of the valve core is provided with two water passage grooves with gradually changing water passage areas, one and two. The two water passage grooves are symmetrically arranged and connected to the water passage chamber. The source water from the inlet enters the water passage chamber and is then output through the two water passage grooves.

[0006] The valve core is positioned so that water passage 1 connects to the first outlet, and water passage 2 connects to the second outlet. At this point, the water paths to both outlets are open, allowing water to be supplied to both. As the valve core rotates, the water flow areas of water passage 1 and water passage 2 gradually change, thus adjusting the water flow rate of the first and second outlets until the valve core rotates to close one outlet, maximizing the water flow rate of the other. This solution allows the two outlets on an electric valve to switch or simultaneously supply water as needed through valve core rotation. Furthermore, when controlling the flow of water through two channels, the electric valve eliminates the need for an additional solenoid valve, optimizing the water path structure and reducing the configuration cost of the water system using the electric valve. Moreover, due to the gradually changing water flow areas of water passage 1 and water passage 2, the rotation of the valve core results in different water flow areas connecting water passage 1 and water passage 2 to their corresponding outlets, thus enabling control and adjustment of the water flow rate.

[0007] Optionally, the outer wall of the valve core is provided with a water passage that is connected to the first water passage and the second water passage. When the valve core rotates counterclockwise, the water passage area of ​​the first water passage gradually increases, and vice versa. When the valve core rotates clockwise, the water passage area of ​​the second water passage gradually increases, and vice versa. The outer wall of the valve core opposite to the water passage is the sealing surface. The rotation of the valve core controls the water passage to connect or block the water passage between the inlet and the first outlet and the second outlet.

[0008] Optionally, multiple water inlets are spaced apart along the valve core axis. When the valve core rotates counterclockwise, the depth of the water inlet in the first water tank gradually increases, and vice versa. When the valve core rotates clockwise, the depth of the water inlet in the second water tank gradually increases, and vice versa.

[0009] Optionally, the end of the water passage trough one and water passage trough two that connects to the water passage has the greatest depth, and multiple water passage troughs one and water passage trough two are distributed at intervals along the valve core axis.

[0010] 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, and the side wall of the sleeve is provided with a water passage groove three located between the first mounting hole and the second mounting hole, the water passage groove three is connected to the water inlet and the water passage cavity.

[0011] 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.

[0012] 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.

[0013] 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.

[0014] Optionally, a fifth sealing ring is provided between the lower end of the sleeve and the inner wall of the valve cover.

[0015] 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.

[0016] The beneficial effects of this utility model are: In this invention, the rotation of the valve core allows two outlets on an electric valve to switch or simultaneously discharge water as needed. Furthermore, when controlling the flow of water in two channels, the electric valve eliminates the need for additional solenoid valves, optimizing the water system structure and reducing the configuration cost of water systems using electric valves. Moreover, due to the gradually changing flow areas of the first and second water channels, the rotation of the valve core results in different flow areas connecting the first and second water channels to their corresponding outlets, thus enabling control and adjustment of the water flow rate.

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

[0022] An electric switching valve with dual water 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 19, a first outlet 09, and a second outlet 17. The valve core 03 has a water passage cavity 13 connected to the inlet 19 inside. The side wall of the valve core 03 is provided with a water passage groove 18 and a water passage groove 22 connected to the water passage cavity 13, and the water passage area gradually changes along the circumference of the valve core 03. The water passage groove 18 and the water passage groove 22 are symmetrically arranged. The rotation of the valve core 03 controls the connection or blockage of the water passage between the inlet 19 and the first outlet 09 and the second outlet 17.

[0023] In this plan, such 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 19, 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 19. The side wall of valve core 03 is provided with water passage groove 18 and water passage groove 22 with gradually changing water passage area. The two water passage grooves are symmetrically arranged and connected to water passage chamber 13. The source water from inlet 19 enters water passage chamber 13 and is then output through the two water passage grooves.

[0024] The valve core 03 is positioned where the first water outlet 09 is connected to the first water passage 18, and the second water outlet 17 is connected to the second water outlet 22. At this point, the water paths to both outlets are open, allowing water to be supplied to both. As the valve core 03 rotates, the water passage areas of the first and second water passages 18 and 22 gradually change, thereby adjusting the water flow rate of the first and second outlets 09 until the valve core 03 rotates to close one outlet, maximizing the water flow rate of the other outlet. This solution, through the rotation of the valve core 03, allows the two outlets on an electric valve to switch or simultaneously supply water as needed. Furthermore, when the electric valve controls the flow of water through the two water paths, no additional solenoid valve is required, optimizing the water path structure and reducing the configuration cost of the water system using the electric valve. Furthermore, due to the gradually changing water flow areas of water flow channels 18 and 22, the rotation of valve core 03 causes different water flow areas to be connected between water flow channels 18 and 22 and the corresponding water outlets, thus enabling the control and adjustment of the water flow rate.

[0025] Furthermore, the outer wall of the valve core 03 is provided with a water passage 20 that is connected to the water passage 18 and the water passage 22. When the valve core 03 rotates counterclockwise, the water passage area of ​​the water passage 18 gradually increases, and vice versa. When the valve core 03 rotates clockwise, the water passage area of ​​the water passage 22 gradually increases, and vice versa. The outer wall of the valve core 03 opposite to the water passage 20 is a sealing surface 23. The rotation of the valve core 03 controls the water passage 20 to connect or block the water passage between the inlet 19 and the first outlet 09 and the second outlet 17.

[0026] Furthermore, multiple water inlets 20 are spaced apart along the axis of valve core 03. When valve core 03 rotates counterclockwise, the depth of water in water groove 18 gradually increases, and vice versa. When valve core 03 rotates clockwise, the depth of water in water groove 22 gradually increases, and vice versa.

[0027] Specifically, water passage trough 18 and water passage trough 22 are symmetrically distributed on both sides of water outlet 20. When valve core 03 rotates counterclockwise, the depth of water passage trough 18 gradually increases; when valve core 03 rotates clockwise, the depth of water passage trough 22 gradually increases. Water passage trough 18 and water passage 22 are symmetrically arranged and remain connected to water outlet 20. When valve core 03 is located at... Figure 2When the valve core 03 is in the middle position, the water passage 18 is connected to the first outlet 09, and the water passage 22 is connected to the second outlet 17. Water can flow from both outlets. When the valve core 03 rotates clockwise, the water passage area connected to the first outlet 09 and the water passage 18 decreases, and the water flow decreases. The water passage area connected to the second outlet 17 and the water passage 22 increases, and the water flow increases. Conversely, the water flow from the first outlet 09 increases, and the water flow from the second outlet 17 decreases. When the sealing surface 23 is aligned with the first outlet 09, the water passage of the first outlet 09 is blocked. When the water passage 20 is aligned with the second outlet 17, the water passage of the second outlet 17 is connected. Conversely, when the water passage 20 is aligned with the first outlet 09, the water passage of the first outlet 09 is connected. When the sealing surface 23 is aligned with the second outlet 17, the water passage of the second outlet 17 is blocked.

[0028] Furthermore, the end of the water passage trough 18 and water passage 22 that connects to the water outlet 20 has the greatest depth, and multiple water passage troughs 18 and water passage 22 are distributed at intervals along the axis of valve core 03.

[0029] Specifically, there are two water passage channels 18 and 22 distributed along the vertical axis of valve core 03, which can ensure the water flow rate.

[0030] Furthermore, such as Figure 3 As shown, the top surface of the valve seat 05 is integrally formed with a sleeve 26. The inner cavity of the sleeve 26 is adapted to the size of the valve core 03. The valve core 03 is rotatably disposed in the inner cavity of the sleeve 26. The side wall of the sleeve 26 is provided with a first mounting hole 24 corresponding to the first water outlet 09 and a second mounting hole 25 corresponding to the second water outlet 17. A first sealing ring 07 is embedded in the inner wall of the first mounting hole 24, and a second sealing ring 14 is embedded in the second mounting hole 25. 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 26 is provided with a water passage groove 3 21 located between the first mounting hole 24 and the second mounting hole 25. The water passage groove 3 21 is connected to the water inlet 19 and the water passage cavity 13.

[0031] 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.

[0032] 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.

[0033] Specifically, such as Figure 1 , Figure 2 , Figure 3As shown, sleeve 26 is vertically mounted on the top surface of valve seat 05. Sleeve 26 and valve seat 05 are integrally formed. Sleeve 26 has an internal cavity that matches the size of valve core 03. Valve core 03 is rotatably mounted in this internal cavity. Opposite first mounting holes 24 and second mounting holes 25 are provided on the side wall of sleeve 26. A matching first sealing ring 07 is installed in the first mounting hole 24. A first support ring 11 for supporting the first sealing ring 07 is provided in the first sealing ring 07. A matching second sealing ring 14 is installed in the second mounting hole 25. A second support ring 15 for supporting the second sealing ring 14 is provided in the second sealing ring 14. The first support ring 11 can support the first sealing ring 07 and prevent the first sealing ring 07 from collapsing. Similarly, the second support ring 15 can support the second sealing ring 14 and prevent the second sealing ring 14 from collapsing. The first sealing ring 07 and the second sealing ring 14 can seal the gap between valve cover 08 and sleeve 26.

[0034] 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 first water passage trough 18 is connected to the first water passage hole 10, the source water can be delivered to the first water outlet 09. Similarly, when the second water passage trough 22 is connected to the second water passage hole 16, the source water can be delivered to the second water outlet 17. The source water enters the water passage chamber 13 through the water inlet 19, passes through the third water passage 21, and then passes through the water outlet 20 to be delivered to the first water passage 18 and the second water passage 22. The valve core 03 rotates the sealing surface 23 and the first water passage hole. When 10 is aligned, the water path of the first outlet 09 is blocked, and the water path of the second outlet 17 is connected; when the valve core 03 is rotated to the position where the sealing surface 23 is aligned with the second water passage 16, the water path of the second outlet 17 is blocked, and the water path of the first outlet 09 is connected; when the valve core 03 is rotated to the position where the sealing surface 23 is located between the first water passage 10 and the second water passage 16, the water paths of both the first outlet 09 and the second outlet 17 are connected. At this time, rotating the valve core 03 can change the area of ​​the water path connected between the water passage 18 and the first outlet 09, and between the water passage 22 and the second outlet 17, thereby realizing the adjustment of the water output.

[0035] Furthermore, the bottom wall of the water passage cavity 13 is provided with a support cylinder 27 that is adapted to and connected to the valve cover 08. A third sealing ring 12 is provided between the support cylinder 27 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.

[0036] Specifically, such as Figure 1As shown, the third sealing ring 12 is pressed between the inner top wall of the valve cover 08 and the support cylinder 27 to seal the gap between the support cylinder 27 and the inner wall of the valve cover 08. The support cylinder 27 and the inner top wall of the valve cover 08 are interlocked. The support cylinder 27 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.

[0037] Furthermore, a fifth sealing ring 06 is provided between the lower end of the sleeve 26 and the inner wall of the valve cover 08.

[0038] Specifically, such as Figure 1 As shown, the fifth sealing ring 06 is embedded in the lower end side wall of the sleeve 26. The fifth sealing ring 06 is used to seal the installation gap between the valve cover 08 and the sleeve 26 to prevent water leakage.

[0039] 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.

[0040] 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.

[0041] 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.
