Description

Technical Field

[0001] This invention relates to the field of water heater technology, and in particular to a flow regulator valve and a water heater containing the same. Background Technology

[0002] For water heater users, the water flow in their homes is always unstable. Fluctuations in water flow or excessive pressure can lead to unpleasant experiences. For example, fluctuations in water flow can cause the water outlet of the water heater to be hot or cold, excessive water pressure may cause parts to crack, or low temperatures may cause the back end to freeze and crack, resulting in the water supply continuing. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art, such as the fluctuation of water flow in water pipes caused by excessive water pressure and the risk of other components in the pipes cracking due to excessive water pressure, and to provide a flow stabilizing valve and a water heater containing the same.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A flow regulating valve, the flow regulating valve comprising:

[0006] The housing includes a first cavity and a second cavity. The first cavity is connected to the second cavity via a connecting port. The first cavity has an inlet and an outlet at its two ends, respectively.

[0007] The valve core and the pressure regulator are disposed in the first cavity and the pressure regulator is disposed in the second cavity. Both the valve core and the pressure regulator are movable along a first direction.

[0008] A telescopic part is provided on the valve core, and the telescopic part can move along a second direction so that the pressure regulator pushes the valve core to move or disengages from the valve core;

[0009] The flow stabilizing valve is configured such that: in a first state, the pressure stabilizing member moves along the first direction to push the telescopic part to move along the first direction, and the water inlet is connected to the water outlet; in a second state, the telescopic part moves along the second direction and disengages from the pressure stabilizing member, the water inlet is closed, and the valve core closes the connection port; in a third state, the pressure stabilizing member can push the valve core to move along the first direction, and the water inlet and the water outlet are closed.

[0010] In this solution, when a user uses water, the pressure stabilizer pushes the telescopic part to move along a first direction, causing the valve core to move and allowing water flow through the flow stabilizing valve. When the water pressure at the inlet increases, the valve core continues to move along the first direction, reducing the flow area at the outlet and achieving relative stability in the water flow. When the inlet water pressure reaches a dangerous point, the pressure stabilizer continues to move upward, pushing the telescopic part to move along a second direction. The telescopic part separates from the valve core, and the valve core moves in the opposite direction to the first direction, closing the inlet and the valve core shutting off the connection port. At this point, the flow rate of the flow stabilizing valve is zero. In the third state, the pressure stabilizer returns to its initial position, and the flow rate of the flow stabilizing valve is zero. The flow stabilizing valve can switch between these three states based on fluctuations in the inlet water pressure. The movement of the valve core, driven by the pressure stabilizer, allows for the opening and closing of the connection port, thereby controlling the flow rate through the flow stabilizing valve. The flow stabilizing valve features a compact design, small size, and simple structure, effectively mitigating the effects of fluctuating water pressure and the risk of other components cracking due to excessive water pressure.

[0011] Preferably, the telescopic part includes an adjusting member and a third elastic member, and an opening is provided on the side wall of the valve core;

[0012] The adjusting member is located through the opening such that one end of the adjusting member is disposed inside the valve core and the other end of the adjusting member is disposed outside the valve core. One end of the third elastic member is connected to the inner wall of the valve core and the other end of the third elastic member abuts against the adjusting member.

[0013] In this design, by moving the adjusting element along the second direction at the opening, the valve core and the pressure regulator can be disengaged, thereby achieving flow regulation and control. The third elastic element provides elastic support for the valve core, ensuring its stability and reliability during operation. The design of the adjusting element and the third elastic element makes the entire telescopic structure simpler and more compact, facilitating manufacturing and maintenance.

[0014] Preferably, the inner wall of the housing is provided with a sliding groove and a first inclined surface, the sliding groove and the first inclined surface being disposed between the first cavity and the second cavity, and the adjusting member being slidable along the first inclined surface.

[0015] When the voltage stabilizer moves into the sliding groove, the adjusting member slides along the first inclined surface to disengage from the voltage stabilizer.

[0016] In this design, the sliding groove and the first inclined surface allow the regulating component to slide along the first inclined surface when the pressure stabilizing component moves into the sliding groove, thus disengaging the regulating component from the pressure stabilizing component. This achieves separation of the pressure stabilizing component and the regulating component when the water pressure is too high, enabling the valve to shut off or regulate the flow rate. The sliding of the regulating component along the first inclined surface ensures stable flow rate of the flow stabilizing valve by adjusting the flow area when the water pressure increases but does not reach a dangerous level. The sliding groove and the first inclined surface simplify the valve's housing structure, reducing additional complex components and mechanical structures, lowering manufacturing and maintenance difficulties, and facilitating the disengagement of the regulating component from the pressure stabilizing component.

[0017] Preferably, the valve core further includes a sleeve, both ends of which are connected to the inner wall of the valve core. One end of the adjusting member is disposed inside the sleeve, and the adjusting member is movable along the second direction within the sleeve. The third elastic member is disposed inside the sleeve.

[0018] In this design, the sleeve provides positioning and support, ensuring the position of the regulating component within the sleeve and guaranteeing coordinated and stable operation of the pressure stabilizing and regulating components. The regulating component moves along a second direction within the sleeve, allowing for flow regulation and control by altering its position, thus ensuring relative flow stability. A third elastic element within the sleeve provides elastic support for the regulating component, ensuring its stability and reliability during operation and preventing excessive water pressure from affecting its movement. The combination of the sleeve, regulating component, and third elastic element provides a stable movement and control method, ensuring the accuracy and stability of the flow control valve under various operating conditions. This further improves the performance and reliability of the flow control valve and meets the needs of various flow control applications.

[0019] Preferably, the adjusting member has a second inclined surface and a third plane at one end within the communication space; the second inclined surface and the third plane are respectively located on opposite sides of the adjusting member.

[0020] The second inclined plane allows the adjusting member and the voltage stabilizer to slide relative to each other; the third plane allows the voltage stabilizer to push the adjusting member to move.

[0021] In this scheme, the second inclined surface allows the adjusting member and the pressure stabilizing member to slide relative to each other. The pressure stabilizing member pushes the second inclined surface to move the adjusting member along the second direction, so that the pressure stabilizing member moves from above the adjusting member to below the adjusting member. The working end of the pressure stabilizing member is close to the third plane of the adjusting member, so that the pressure stabilizing member can push the adjusting member to move, thereby pushing the valve core along the first direction, and further regulating the flow rate.

[0022] Preferably, the voltage regulator has a stop provided on the side near the valve core.

[0023] In a first state, the stop pushes the adjusting member to move along a first direction; in a second state, the stop pushes the adjusting member to move along a second direction so that the voltage stabilizer disengages from the adjusting member; in a third state, the stop slides relative to the second inclined plane so that the stop moves to a side closer to the third plane.

[0024] In this design, the stop block pushes the regulating element to move along a first direction. In the first state, the stop block acts as a driving force, causing the regulating element to move along the first direction, which in turn causes the valve core to move along the first direction, adjusting the flow rate. In the second state, the stop block pushes the regulating element to move along a second direction, causing the pressure stabilizing element to disengage from the regulating element. In this state, the stop block's function is to separate the pressure stabilizing element from the regulating element, closing the flow stabilizing valve and reducing the flow rate through it to zero. In the third state, the stop block slides relative to the second inclined plane, moving from above the regulating element to below it, and the pressure stabilizing element moves to the side closer to the third plane. In this state, the stop block's movement in the opposite direction of the first direction brings it closer to the third plane, preparing for the next state of operation. Through the switching of these states and the function of the stop block, the flow stabilizing valve can achieve different operational objectives, including regulating flow rate, closing flow rate, and preparing for the transition to the next state. This design improves the controllability and adaptability of the flow stabilizing valve, enabling it to switch operating states under different water pressure ranges.

[0025] Preferably, the flow regulating valve further includes a first elastic element, one end of which is disposed on the inner wall of the first cavity near the outlet, and the other end of which is connected to the valve core; and / or,

[0026] The flow regulator also includes a second elastic element, one end of which is disposed in the second cavity, and the other end of which abuts against the pressure regulator.

[0027] In this design, the first elastic element provides elastic support and rebound force, ensuring the stability and reliability of the valve core's movement. When the water pressure exceeds the danger point, it provides driving force for the valve core to move in the opposite direction of the first direction. After the water pressure exceeds the danger point, the regulating element and the pressure stabilizing element disengage, and the valve core moves to close the connection port and the inlet, resulting in zero flow through the flow stabilizing valve. The second elastic element has one end located within the second cavity and the other end abutting against the pressure stabilizing element. This configuration provides additional elastic support and stability. When the valve core closes the connection port and the inlet, it provides driving force for the pressure stabilizing element to move in the opposite direction of the first direction, allowing the pressure stabilizing element to return to its initial state. This ensures the accuracy and stability of the pressure stabilizing element's movement in the third state. Through the above-mentioned elastic element configuration, the flow stabilizing valve can achieve better feedback and regulation, improving its performance and accuracy, and making the switching between the three operating states of the pressure stabilizing valve more stable.

[0028] Preferably, the housing is further provided with a pressure port, the pressure port being located at the end away from the pressure stabilizing member and close to the second elastic member; and / or,

[0029] Along the first direction, the length of the valve core is not less than the length of the communication port.

[0030] In this scheme, by setting a pressure port, the pressure at both ends of the pressure stabilizer is unbalanced, which facilitates the water flowing into the flow stabilizing valve to push the pressure stabilizer to move along the first direction. By bringing the pressure port close to one end of the second elastic element, after the valve core closes the flow stabilizing valve's connection port and water inlet, the pressure stabilizer returns to its initial state under the action of the second elastic element. The pressure stabilizer returns to the bottom of the regulating element, providing a basis for the flow stabilizing valve to start its cycle again after closing.

[0031] The length of the valve core is not less than the length of the connection port, which can ensure the flow control accuracy and stability of the flow regulator under different working conditions. When the water pressure is too high, the valve core will close the connection port to prevent leakage caused by size mismatch and improve the stability and reliability of the flow regulator.

[0032] Preferably, the valve core includes at least one first support and a throttling column.

[0033] One end of the first bracket is connected to the inner wall of the valve core, and the other end of the first bracket is connected to the throttling column. A gap is provided between adjacent first brackets, and the throttling column is located at the end near the outlet; and / or,

[0034] The valve core includes at least one second support and a sealing post.

[0035] One end of the second bracket is connected to the inner wall of the valve core, and the other end of the second bracket is connected to the sealing column. A gap is provided between adjacent second brackets, and the sealing column is located at one end near the water inlet.

[0036] In this design, the throttling column is positioned near the outlet. This design restricts fluid flow, regulating the flow rate, and the gap design ensures uniform fluid distribution and stable flow. The sealing column is positioned near the inlet. This design provides a sealing effect, preventing fluid leakage, and the gap design also ensures uniform fluid distribution and stable flow. The flow regulator valve allows for precise flow regulation and control, maintaining fluid stability and uniformity. The throttling and sealing columns provide restriction and containment of fluid flow, thus achieving reliable flow regulation and sealing.

[0037] A water heater, comprising the flow regulating valve as described above.

[0038] In this solution, when a user uses water, the pressure stabilizer pushes the telescopic part to move along a first direction, causing the valve core to move and allowing water flow through the flow stabilizing valve. When the water pressure at the inlet increases, the valve core continues to move along the first direction, reducing the flow area at the outlet and achieving relative stability in the water flow. When the inlet water pressure reaches a dangerous point, the pressure stabilizer continues to move upward, pushing the telescopic part to move along a second direction. The telescopic part separates from the valve core, and the valve core moves in the opposite direction to the first direction, closing the inlet and the valve core shutting off the connection port. At this point, the flow rate of the flow stabilizing valve is zero. In the third state, the pressure stabilizer returns to its initial position, and the flow rate of the flow stabilizing valve is zero. The flow stabilizing valve can switch between these three states based on fluctuations in the inlet water pressure. The movement of the valve core, driven by the pressure stabilizer, allows for the opening and closing of the connection port, thereby controlling the flow rate through the flow stabilizing valve. The flow stabilizing valve features a compact design, small size, and simple structure, effectively mitigating the effects of fluctuating water pressure and the risk of other components cracking due to excessive water pressure.

[0039] Based on common knowledge in the field, the above-mentioned preferred technical solutions can be freely combined to obtain the preferred embodiments of this application.

[0040] The positive and progressive effects of this invention are as follows: When a user uses water, the pressure stabilizer can push the telescopic part to move along a first direction, causing the valve core to move and allowing water flow through the flow stabilizing valve. When the water pressure flowing into the inlet increases, the valve core continues to move along the first direction, reducing the flow area of ​​the outlet and achieving relative stability of the water flow. When the inflow water pressure reaches a dangerous point, the pressure stabilizer continues to move upward, pushing the telescopic part to move along a second direction. The telescopic part separates from the valve core, and the valve core moves in the opposite direction to the first direction, closing the inlet and the valve core shutting off the connection port. At this time, the flow rate of the flow stabilizing valve is zero. In the third state, the pressure stabilizer returns to its initial position, and the flow rate of the flow stabilizing valve is zero. The flow stabilizing valve can switch between three states according to the water pressure fluctuations at the inlet. The movement of the valve core is driven by the pressure stabilizer, enabling the opening and closing of the connection port, thereby controlling the flow rate through the flow stabilizing valve. The flow stabilizing valve has a compact design, small size, and simple structure, which can solve the problems of sudden temperature changes caused by user water pressure fluctuations and the risk of other components cracking due to excessive water pressure.

[0077] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments.

[0078] This embodiment provides a flow stabilizing valve 100, such as Figures 1-7As shown, the flow regulator 100 includes a housing 1, a valve core 2, a pressure regulator 4, and a telescopic part 3. The housing 1 has a first cavity 11 and a second cavity 12. The first cavity 11 is connected to the second cavity 12 through a connecting port 13. The two ends of the first cavity 11 are respectively provided with an inlet 111 and an outlet 112. The valve core 2 is disposed in the first cavity 11, and the pressure regulator 4 is disposed in the second cavity 12. Both the valve core 2 and the pressure regulator 4 are movable along the first direction A. The telescopic part 3 is disposed on the valve core 2. The telescopic part 3 can move along the second direction B so that the pressure regulator 4 pushes the valve core 2 to move or disengages from the valve core 2.

[0079] The flow stabilizing valve 100 is configured such that: in a first state, the pressure stabilizing member 4 moves along the first direction A, pushing the telescopic part 3 to move along the first direction A, and the inlet 111 connects to the outlet 112; in a second state, the telescopic part 3 moves along the second direction B and disengages from the pressure stabilizing member 4, the inlet 111 is closed, and the valve core 2 closes the connecting port 13; in a third state, the pressure stabilizing member 4 can push the valve core 2 to move along the first direction A, and the inlet 111 and outlet 112 are closed.

[0080] In practical use, when the user uses water, the pressure stabilizer 4 can push the telescopic part 3 to move along the first direction A, and the valve core 2 moves, so that the water flow in the flow stabilizing valve 100 can pass through. When the water pressure flowing into the inlet 111 increases, the valve core 2 continues to move along the first direction A, and the flow area of ​​the outlet 112 decreases, so as to achieve relative stability of the water flow. When the inflow water pressure reaches the danger point, the pressure stabilizer 4 continues to move upward, pushing the telescopic part 3 to move along the second direction B. The telescopic part 3 completes the separation from the valve core 2, and the valve core 2 moves in the opposite direction to the first direction A. The inlet 111 is closed and the valve core 2 closes the connecting port 13. At this time, the flow of the flow stabilizing valve 100 is zero. In the third state, the pressure stabilizer 4 returns to the initial position, and the flow of the flow stabilizing valve 100 is zero. The flow regulator 100 can switch between three states according to the water pressure fluctuations at the inlet 111. The movement of the valve core 2 is driven by the pressure stabilizing component 4, which can open and close the connection port 13, thereby controlling the flow rate through the flow regulator 100. The flow regulator 100 has a compact design, small size, and simple structure, which can solve the problem of sudden temperature changes caused by water pressure fluctuations and the risk of other components bursting due to excessive water pressure.

[0081] Specifically, such as Figure 3As shown, the telescopic part 3 includes an adjusting member 31 and a third elastic member 32. An opening 21 is provided on the side wall of the valve core 2. The adjusting member 31 is positioned inside the valve core 2 through the opening 21, while the other end of the adjusting member 31 is positioned outside the valve core 2. One end of the third elastic member 32 is connected to the inner wall of the valve core 2, and the other end of the third elastic member 32 abuts against the adjusting member 31. In addition, the adjusting member 31 is also provided with a protrusion. In the initial state, the protrusion is engaged with the opening 21, and the protrusion can limit the movement direction and movement distance of the adjusting member 31. In the initial state, the third elastic member 32 is in a compressed state. In this embodiment, the third elastic member 32 is a spring, but the third elastic member 32 in this embodiment is not limited to a spring.

[0082] By moving the adjusting member 31 along the second direction B through the opening 21, the valve core 2 and the pressure regulator 4 can be disengaged, thereby achieving flow regulation and control. The third elastic member 32 provides elastic support for the valve core 2. After the adjusting member 31 moves along the second direction B, when the valve core 2 moves in the opposite direction A, the third elastic member 32 provides driving force for the adjusting member 31 to move in the opposite direction B, allowing the adjusting member 31 to return to its initial state and ensuring the stability and reliability of the valve core 2 during operation. The design of the adjusting member 31 and the third elastic member 32 makes the entire telescopic part 3 structure simpler and more compact, facilitating manufacturing and maintenance.

[0083] Specifically, the inner wall of the housing 1 is provided with a sliding groove 14 and a first inclined surface 15. The sliding groove 14 and the first inclined surface 15 are located between the first cavity 11 and the second cavity 12. The adjusting member 31 can slide along the first inclined surface 15. When the voltage stabilizer 4 moves into the sliding groove 14, the adjusting member 31 slides along the first inclined surface 15 so that the adjusting member 31 and the voltage stabilizer 4 are disengaged from each other.

[0084] With the sliding groove 14 and the first inclined surface 15, when the pressure stabilizing component 4 moves into the sliding groove 14, the adjusting component 31 can slide along the first inclined surface 15, thereby disengaging the adjusting component 31 from the pressure stabilizing component 4. This achieves the separation of the pressure stabilizing component 4 from the adjusting component 31 when the water pressure is too high, thus achieving the purpose of shutting off or regulating the flow rate. The sliding of the adjusting component 31 along the first inclined surface 15 ensures the stability of the flow rate of the flow stabilizing valve 100 when the water pressure increases but does not reach the danger point, by adjusting the flow area. The sliding groove 14 and the first inclined surface 15 simplify the structure of the housing 1 of the flow stabilizing valve 100, reduce additional complex components and mechanical structures, lower the difficulty of manufacturing and maintenance, and facilitate the disengagement of the adjusting component 31 from the pressure stabilizing component 4.

[0085] Specifically, such as Figure 4As shown, the valve core 2 also includes a sleeve 22, both ends of which are connected to the inner wall of the valve core 2. One end of the adjusting member 31 is disposed inside the sleeve 22. The adjusting member 31 is movable within the sleeve 22 along the second direction B. The third elastic member 32 is disposed inside the sleeve 22.

[0086] The sleeve 22 provides positioning and support, ensuring the position of the regulating element 31 within the sleeve 22 and guaranteeing the coordinated and stable operation of the pressure stabilizing element 4 and the regulating element 31. The regulating element 31 moves along the second direction B within the sleeve 22, and by changing its position within the sleeve 22, the relative stability of the flow rate can be maintained. The third elastic element 32 provides elastic support for the regulating element 31 within the sleeve 22, ensuring the stability and reliability of the regulating element 31 during operation and preventing excessive water pressure from affecting the movement of the third elastic element 32. The combination of the sleeve 22 of the valve core 2, the regulating element 31, and the third elastic element 32 provides a stable working environment for the movement of the regulating element 31, ensuring the accuracy and stability of the flow stabilizing valve 100 under different operating conditions. This will further improve the performance and reliability of the flow stabilizing valve 100 and meet various flow control requirements.

[0087] Specifically, such as Figure 7 As shown, the regulating member 31 has a second inclined surface 311 and a third plane 312 at one end within the space of the connecting port 13. The second inclined surface 311 and the third plane 312 are respectively located on opposite sides of the regulating member 31. The second inclined surface 311 allows the regulating member 31 and the pressure stabilizing member 4 to slide relative to each other. The third plane 312 allows the pressure stabilizing member 4 to push the regulating member 31 to move. The second inclined surface 311 allows the regulating member 31 and the pressure stabilizing member 4 to slide relative to each other. By pushing the second inclined surface 311, the pressure stabilizing member 4 pushes the regulating member 31 to move along the second direction B, causing the pressure stabilizing member 4 to move from above the regulating member 31 to below the regulating member 31. This causes the working end of the pressure stabilizing member 4 to approach the third plane 312 of the regulating member 31, allowing the flow stabilizing valve 100 to return to its initial state. The pressure stabilizing member 4 can push the regulating member 31 to move, thereby moving the valve core 2 along the first direction A, and further regulating the flow rate.

[0088] Specifically, a stop 41 is provided on the side of the pressure regulator 4 near the valve core 2. The stop 41 is located within the space of the communication port 13. In the first state, the stop 41 pushes the adjusting member 31 to move along the first direction A. In the second state, the stop 41 pushes the adjusting member 31 to move along the second direction B, so that the pressure regulator 4 and the adjusting member 31 disengage from each other. In the third state, the stop 41 slides relative to the second inclined surface 311, and the adjusting member 31 moves along the second direction B. When the stop 41 moves to the bottom of the adjusting member 31, the third elastic member 32 pushes the adjusting member 31 to move in the opposite direction of the second direction B, so that the adjusting member 31 returns to its initial state. Finally, the stop 41 moves to the side near the third plane 312. The stop 41 has rounded corners to reduce wear on the stop 41 during the process of disengaging from the adjusting member 31.

[0089] In the first state, the stop block 41 provides a pushing force, causing the regulating member 31 to move along the first direction A, which in turn causes the valve core 2 to move along the first direction A, adjusting the flow rate. In the second state, the stop block 41 pushes the regulating member 31 to move along the second direction B, causing the pressure stabilizing member 4 to disengage from the regulating member 31. In this state, the function of the stop block 41 is to separate the pressure stabilizing member 4 from the regulating member 31, thereby closing the flow stabilizing valve 100 and making the flow rate through the flow stabilizing valve 100 zero. In the third state, the stop block 41 slides relative to the second inclined plane 311, causing the stop block 41 to move from above the regulating member 31 to below the regulating member 31, and the pressure stabilizing member 4 moves to the side closer to the third plane 312. In this state, the movement of the stop block 41 in the opposite direction of the first direction A brings it closer to the side of the third plane 312, preparing for the operation of the next state. Through the switching of the above states and the function of the stop block 41, the flow stabilizing valve 100 can achieve different operational objectives, including adjusting the flow rate, closing the flow rate, and preparing for the transition to the next state. This design can improve the controllability and adaptability of the flow regulator 100, enabling the flow regulator 100 to switch its working state under different water pressure ranges.

[0090] Specifically, the flow regulator 100 further includes a first elastic element 5, one end of which is disposed on the inner wall of the first cavity 11 near the outlet 112, and the other end of which is connected to the valve core 2. The flow regulator 100 also includes a second elastic element 6, one end of which is disposed in the second cavity 12, and the other end of which abuts against the pressure regulator 4.

[0091] like Figure 5As shown, the first elastic element 5 provides elastic support and rebound force, ensuring the stability and reliability of the valve core 2's movement. When the water pressure exceeds the danger point, it provides driving force for the valve core 2 to move in the opposite direction of the first direction A. After the water pressure exceeds the danger point, the regulating element 31 and the pressure stabilizing element 4 disengage, and the valve core 2 moves to close the connecting port 13 and the inlet 111, resulting in zero flow through the flow stabilizing valve 100. One end of the second elastic element 6 is located inside the second cavity 12, and the other end abuts against the pressure stabilizing element 4. This configuration provides additional elastic support and stability, allowing the pressure stabilizing element 4 to move in the opposite direction of the first direction A after the valve core 2 closes the connecting port 13 and the inlet 111. This restores the pressure stabilizing element 4 to its initial state, ensuring the accuracy and stability of the pressure stabilizing element 4's movement in the third state. Through the above-mentioned elastic element configuration, the flow stabilizing valve 100 can achieve better feedback and regulation, improving its performance and accuracy, and making the switching of the pressure stabilizing valve between the three working states more stable.

[0092] Among them, such as Figure 6 As shown, the housing 1 is also provided with a pressure port 16, which is located at the end away from the pressure stabilizer 4 and close to the second elastic member 6. Along the first direction A, the length of the valve core 2 is not less than the length of the connecting port 13. By setting the pressure port 16, the pressure at both ends of the pressure stabilizer 4 is unbalanced, which facilitates the water flowing into the flow stabilizing valve 100 to push the pressure stabilizer 4 to move along the first direction A. By bringing the pressure port 16 close to the end of the second elastic member 6, after the valve core 2 closes the connecting port 13 and the water inlet 111 of the flow stabilizing valve 100, the pressure stabilizer 4 returns to its initial state under the action of the second elastic member 6. The pressure stabilizer 4 returns to the bottom of the regulating member 31, providing a basis for the flow stabilizing valve 100 to start its cycle operation again after closing.

[0093] The length of valve core 2 is not less than the length of connection port 13, which can ensure the flow control accuracy and stability of flow stabilizing valve 100 under different working conditions. When the water pressure is too high, valve core 2 will close connection port 13 to prevent leakage caused by size mismatch and improve the stability and reliability of flow stabilizing valve 100.

[0094] The valve core 2 includes at least one first bracket 23 and a throttling column 24. One end of the first bracket 23 is connected to the inner wall of the valve core 2, and the other end of the first bracket 23 is connected to the throttling column 24. A gap is provided between adjacent first brackets 23. The throttling column 24 is located at one end near the outlet 112. The valve core 2 also includes at least one second bracket 25 and a sealing column 26. One end of the second bracket 25 is connected to the inner wall of the valve core 2, and the other end of the second bracket 25 is connected to the sealing column 26. A gap is provided between adjacent second brackets 25. The sealing column 26 is located at one end near the inlet 111.

[0095] A throttling column 24 is positioned near the outlet 112. This design restricts fluid flow through the throttling column 24, regulating the flow rate, and the gap design ensures uniform fluid distribution and stable flow. A sealing column 26 is positioned near the inlet 111. This design provides a sealing effect, preventing fluid leakage, and the gap design also ensures uniform fluid distribution and stable flow. The flow regulator 100 enables precise flow regulation and control, maintaining fluid stability and flow uniformity. The throttling column 24 and sealing column 26 provide restriction and sealing of fluid flow, thereby achieving reliable flow regulation and sealing effects.

[0096] This embodiment also provides a water heater, which includes the flow regulator 100 as described above. When the user uses water, the pressure regulator 4 can push the telescopic part 3 to move along the first direction A, and the valve core 2 moves, so that the water flow in the flow regulator 100 can pass through. When the water pressure flowing into the inlet 111 increases, the valve core 2 continues to move along the first direction A, and the flow area of ​​the outlet 112 decreases, so as to achieve relative stability of the water flow. When the inflow water pressure reaches the danger point, the pressure regulator 4 continues to move upward, pushing the telescopic part 3 to move along the second direction B. The telescopic part 3 completes the separation from the valve core 2, and the valve core 2 moves in the opposite direction to the first direction A. The inlet 111 is closed and the valve core 2 closes the connecting port 13. At this time, the flow of the flow regulator 100 is zero. In the third state, the pressure regulator 4 returns to the initial position, and the flow of the flow regulator 100 is zero. The flow regulator 100 can switch between three states according to the water pressure fluctuations at the inlet 111. The movement of the valve core 2 is driven by the pressure stabilizing component 4, which can open and close the connection port 13, thereby controlling the flow rate through the flow regulator 100. The flow regulator 100 has a compact design, small size, and simple structure, which can solve the problem of sudden temperature changes caused by water pressure fluctuations and the risk of other components bursting due to excessive water pressure.

[0097] In practical use, the first elastic element 5, the second elastic element 6, and the third elastic element 32 are in a compressed state, and each component is in its initial position. When the user uses water and turns on the faucet, the pressure at the upper and lower ends of the pressure port 16 becomes unbalanced, and a negative pressure is formed at the upper end of the pressure port 16. At this time, when the water pressure fluctuates below the danger point, the pressure stabilizing element 4 moves upward under the push of the water pressure, overcoming the elastic force of the second elastic element 6. During the movement, the stop 41 on the pressure stabilizing element 4 pushes the adjusting element 31 in contact with it, thereby driving the valve core 2 to move along the first direction A, overcoming the elastic force of the first elastic element 5. The sealing column 26 on the valve core 2 leaves the inlet 111, opening the inlet 111. The water flows through the interior of the valve core 2 and finally flows out from the outlet 112. Since the flow area formed by the throttling column 24 and the outlet 112 gradually decreases during the movement of the valve core 2, the flow rate can be kept stable by reducing the flow area when the pressure increases, and there will be no flow rate change. Figure 4 As shown.

[0098] When the water pressure reaches a dangerous level, the pressure stabilizer 4 continues to move upward, and the stop block 41 pushes the adjusting member 31 onto the first inclined plane 15. Under the action of the stop block 41 and the first inclined plane 15, the adjusting member 31 overcomes the elastic force of the third elastic member 32 and moves along the second direction B. Figure 5 As shown, with the continued pushing of the stop 41, the adjusting rod loses its limit, and under the action of the first elastic element 5, the valve core 2 moves in the opposite direction of the first direction A. The sealing column 26 seals the water inlet 111, and under the action of the third elastic element 32, the adjusting element 31 returns to its original position. At this time, due to the valve core 2, the water in the second cavity 12 cannot enter the first cavity 11 through the connecting port 13, thus achieving a complete seal of the flow stabilizing valve 100. Figure 6 As shown, due to the presence of pressure port 16, pressure stabilizer 4 is unaffected. Under the action of water pressure, pressure stabilizer 4 moves to its limit position and no more water will flow out, ensuring that the back end will not crack due to excessive water pressure or freeze due to low temperature, thus avoiding unnecessary losses.

[0099] When the user turns off the faucet, the pressure at both ends of the pressure port 16 reaches equilibrium. Under the action of the second elastic element 6, the pressure stabilizing element 4 moves in the opposite direction of the first direction A. When it passes the adjusting element 31, due to the second inclined surface 311 on the adjusting element 31, the stop 41 causes it to overcome the elastic force of the third elastic element 32 and move along the second direction B. After the stop 41 passes, the adjusting element 31 returns to its original position under the action of the third elastic element 32, and the final state is as follows. Figure 3 As shown. This structure adopts a purely mechanical structure, requiring no energy consumption; it is small in size, consumes no power, has a simple structure, is easy and feasible to install, and can be installed in any direction. It can solve the problems caused by sudden temperature fluctuations when the water temperature fluctuates and the risk of cracking due to excessive water pressure.
