Description

Technical Field

[0001] This invention relates to the field of water heaters, and in particular to a flow regulating valve. Background Technology

[0002] In daily life, for water heater users, fluctuations in water pressure, changes in water flow, temperature, pipe conditions, and different water demand can all lead to fluctuations in flow and changes in water pressure. Fluctuations in water flow or excessive pressure can bring a bad user experience. For example, fluctuations in water flow can cause the water outlet of the water heater to be sometimes cold and sometimes hot, while excessive water pressure may cause parts to crack or the back end to freeze and crack due to low temperature, but water can still be supplied. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art, which can lead to a poor user experience due to fluctuations in water flow or excessive pressure, and to provide a flow stabilizing valve.

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

[0005] A flow regulating valve, characterized in that it comprises:

[0006] Valve chamber, through which water flows;

[0007] A flow stabilizer fan is disposed inside the valve cavity and can rotate about an extension line in any direction other than the water flow direction to adjust the size of the projected area of ​​the flow stabilizer fan on the cross section of the valve cavity along the water flow direction.

[0008] The rotation angle of the flow stabilizer fan gradually increases from the minimum angle to the maximum angle as the water flow speed increases. When the flow stabilizer fan is at its minimum angle, the projected area is the smallest, and when the flow stabilizer fan is at its maximum angle, the projected area is the largest.

[0009] In this solution, the aforementioned structure is used. The flow stabilizer fan is installed inside the valve chamber and gradually rotates under the impact of water flow, increasing its projected cross-sectional area in the water flow direction to block the water flow. The faster the water flow velocity and the stronger the impact, the larger the rotation angle of the flow stabilizer fan and the stronger the blocking area, thereby reducing the impact force of the water flow and achieving a flow stabilization effect. The rotation angle of the flow stabilizer fan is between the minimum and maximum angles. At the minimum angle, the cross-sectional area of ​​the flow stabilizer fan along the water flow direction is controlled to ensure the stability of the normal water flow. At the maximum angle, the flow stabilizer fan is fully open, maximizing its cross-sectional area along the water flow direction and achieving the maximum blocking effect. In use, the flow stabilizer fan can dynamically adjust its rotation angle according to the water flow, achieving real-time adaptive dynamic flow stabilization without the need for additional structures such as control structures, resulting in a better user experience.

[0010] Preferably, the flow control valve is held at the minimum angle by a maintaining mechanism. More preferably, the maintaining mechanism is an elastic element.

[0011] In this design, using the aforementioned structure, the flow stabilizer fan needs to tend to move towards its minimum position under external force to counteract the impact of the water flow. When the water flow force reaches a certain level, the flow stabilizer fan can overcome this tendency and rotate. This tendency is provided by a maintaining mechanism, which continuously provides a force opposite to the water flow direction to the flow stabilizer fan, allowing it to maintain its minimum angle. An elastic element is chosen for the maintaining mechanism. Based on the characteristics of elastic elements, the greater the force applied, the greater their self-restoring force. This characteristic means that the greater the water flow, the greater the rotation angle of the flow stabilizer fan. The elastic element, further compressed by the fan's rotation, exerts a greater restoring force, which balances the impact of the water flow, allowing the flow stabilizer fan to maintain a specific angle.

[0012] Preferably, the flow regulator further includes:

[0013] A valve seat is disposed within the valve cavity, dividing the valve cavity into a first cavity and a second cavity. The valve seat also includes a through hole through which the first cavity and the second cavity are connected.

[0014] A flow stabilizer plug passes through the through hole. The first end of the flow stabilizer plug along the water flow direction is fixed to the flow stabilizer fan in the first cavity. When the flow stabilizer fan is at its maximum angle, the flow stabilizer plug can move from the first position to the second position along the water flow direction under the action of the water flow.

[0015] In the first position, the through hole is open; in the second position, the flow stabilizer plug closes the through hole.

[0016] In this solution, the above structure is adopted. The flow stabilizing valve is also equipped with a valve seat and a flow stabilizing plug. The flow stabilizing plug can be pushed by the water flow impacting the flow stabilizing fan when the flow stabilizing fan has rotated to its maximum angle, and close the valve seat. This achieves the protection of the water circuit by cutting off the water flow when the water flow is too rapid, the water flow rate is too large, the water pressure is too high, and the flow stabilizing fan has reached its maximum angle and can no longer stabilize the flow.

[0017] Preferably, the flow regulator further includes an elastic reset member that abuts against the flow regulator in the direction of the first end of the flow regulator and holds it in the first position.

[0018] In this solution, the above-mentioned structure is adopted. The flow stabilizer is reset by the elastic reset component and a pre-tightening force is applied to keep it in the first position. This makes the water flow more stable. When the force is less than the pre-tightening force, the flow stabilizer will not move and will not interfere with the water flow, thus ensuring normal water use for users.

[0019] Preferably, the elastic reset member is disposed in the second cavity and abuts against the second end of the flow stabilizer;

[0020] The second end of the flow stabilizer extends toward the valve cavity wall to form a convex edge. When the flow stabilizer is in the first position, the convex edge abuts against the side of the through hole of the valve seat facing the second cavity and restricts the flow stabilizer from moving toward the first cavity.

[0021] In this solution, the above-mentioned structure is adopted, and the elastic reset member is set in the second cavity. It is used to push the flow stabilizer to move to the first position when the water flow is not large and the water pressure is low. At the same time, the convex edge limits the flow stabilizer to prevent it from falling out of the through hole.

[0022] Preferably, the second cavity is further provided with an elastic element mounting seat, the elastic element mounting seat is provided with an annular groove, and one end of the elastic reset element is engaged in the annular groove and abuts against the elastic element mounting seat.

[0023] In this solution, the above structure is used, and the elastic reset component can be better fixed through the annular groove.

[0024] Preferably, the inner wall of the valve cavity of the flow stabilizing valve is further provided with a sliding groove arranged along the water flow direction, and the rotating shaft of the flow stabilizing fan is arranged in the sliding groove.

[0025] In this solution, the above structure is adopted. The rotating shaft of the flow stabilizer fan is fixed in the slide groove to achieve synchronous movement with the flow stabilizer plug. The slide groove guides and limits its movement, making the flow stabilizer fan more secure.

[0026] Preferably, the flow stabilizer is hollow inside, the first end of the flow stabilizer is circumferentially provided with a water inlet, the second end of the flow stabilizer is provided with a water outlet, and the flow stabilizer is hollow inside and connected to the water inlet and the water outlet;

[0027] In the first position, the water inlet protrudes from the valve seat;

[0028] In the second position, the inlet is closed by the valve seat.

[0029] In this scheme, the above-mentioned structure is adopted. The flow stabilizer is a hollow structure with an opening at each end for water flow. The inlet located in the first chamber is open in the first position to allow water flow, while it is closed by the valve seat in the second position to cut off the water flow.

[0030] Preferably, the valve cavity is further provided with a limiting post, which is located on the side of the flow stabilizer fan in the opposite direction to the water flow direction. The limiting post is located on the rotation path of the flow stabilizer fan and limits the flow stabilizer fan to the minimum angle.

[0031] In this solution, the aforementioned structure, by setting a limiting post to block the flow stabilizer fan, prevents the fan from rotating too small an angle under reset action, thus avoiding loss of flow stabilization effect. The limiting post can limit its rotation, keeping it at a minimum angle under low voltage conditions, thereby improving the flow stabilization effect.

[0032] Preferably, there are two current-regulating fans, which are symmetrically arranged along the axis of rotation.

[0033] In this solution, the above structure provides better current stabilization.

[0034] The significant advantages of this invention are as follows: This invention provides a flow-stabilizing fan installed within a valve cavity. Under the impact of water flow, it gradually rotates, increasing its projected cross-sectional area in the water flow direction to block the flow. The faster the water flow and the stronger the impact, the larger the rotation angle of the flow-stabilizing fan, and the stronger the blocking area, thereby reducing the impact force of the water flow and achieving a flow-stabilizing effect. The rotation angle of the flow-stabilizing fan is between its minimum and maximum angle. At the minimum angle, the cross-sectional area of ​​the flow-stabilizing fan along the water flow direction is controlled to ensure stable normal water flow. At the maximum angle, the flow-stabilizing fan is fully open, maximizing its cross-sectional area along the water flow direction and achieving the maximum blocking effect. In use, the flow-stabilizing fan can dynamically adjust its rotation angle according to the water flow, achieving real-time adaptive dynamic flow stabilization without the need for additional structures such as control mechanisms, resulting in a better user experience.

[0054] Valve chamber 5 Detailed Implementation

[0055] 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 described herein.

[0056] like Figures 1 to 5 As shown, this embodiment provides a flow stabilizing valve, which includes a valve cavity 5 and a flow stabilizing fan 1. The valve cavity 5 is used for water flow. The flow stabilizing fan 1 is disposed in the valve cavity 5 and can rotate about the extension line of any direction other than the water flow direction as an axis to adjust the size of the projected area of ​​the flow stabilizing fan 1 on the cross section of the valve cavity 5 along the water flow direction. The rotation angle of the flow stabilizing fan 1 gradually rotates from the minimum angle to the maximum angle as the water flow speed increases. When the flow stabilizing fan 1 is at the minimum angle, the projected area is the smallest, and when the flow stabilizing fan 1 is at the maximum angle, the projected area is the largest.

[0057] In this embodiment, the flow stabilizing valve is a cavity that is open at both ends, and the flow stabilizing fan 1 is disposed in the cavity, which can rotate in the direction of water flow and block the water flow.

[0058] The flow stabilizer fan 1 is installed inside the valve chamber 5 and gradually rotates under the impact of water flow, increasing its projected cross-sectional area in the direction of water flow to block the flow. The faster the water flow and the stronger the impact, the larger the rotation angle of the flow stabilizer fan 1, and the stronger the blocking area, thereby reducing the impact force of the water flow and achieving a flow stabilization effect. The rotation angle of the flow stabilizer fan 1 is between the minimum and maximum angles. At the minimum angle, the cross-sectional area of ​​the flow stabilizer fan 1 along the direction of water flow is controlled to ensure the stability of normal water flow. At the maximum angle, the flow stabilizer fan 1 is fully open, maximizing its cross-sectional area along the direction of water flow and achieving the maximum blocking effect. In use, the flow stabilizer fan 1 can dynamically adjust its rotation angle according to the water flow, achieving real-time adaptive dynamic flow stabilization without the need for additional structures such as control structures, resulting in a better user experience.

[0059] in, Figure 1 This is a schematic diagram of the flow stabilizer 1 in its minimum angle state. At this time, the flow stabilizer 2 is in the first position, and the flow stabilizer valve is in the open state.

[0060] in, Figure 2 This is a schematic diagram of the flow stabilizer fan 1 at its maximum angle. At this point, the flow stabilizer plug 2 is in the first position, and the flow stabilizer valve is in the open state. In this embodiment, the maximum angle of flow stabilization is 90 degrees to the direction of water flow.

[0061] in, Figure 3 This is a schematic diagram of the flow stabilizer fan 1 at its maximum angle. At this point, the flow stabilizer plug 2 is in the second position, and the flow stabilizer valve is closed.

[0062] like Figures 1 to 3 , Figure 5 As shown, the flow control valve is held at its minimum angle by the maintaining mechanism 12. Preferably, the maintaining mechanism 12 is an elastic element.

[0063] In this embodiment, the flow stabilizer fan 1 is mounted on a rotating shaft 11, and the maintaining mechanism 12 is a spring. The spring is mounted on the rotating shaft 11, with its end extending to abut against the side of the flow stabilizer fan 1 opposite to the water flow direction. When the flow stabilizer fan 1 rotates, it causes the end of the spring to twist, generating a counterforce. Since this embodiment has two oppositely arranged flow stabilizers 1, the two ends of the spring in the maintaining mechanism 12 extend to both sides of the two flow stabilizers and are fixed in grooves on the surface of the flow stabilizers. When the two flow stabilizers 1 rotate in an opening motion, the corresponding forces at both ends of the spring rotate, causing the spring to twist and generate a restoring force.

[0064] In this embodiment, the flow stabilizer fan 1 needs to have a tendency to move towards its minimum position under the action of external force in order to counteract the impact force of the water flow. When the water flow force reaches a certain level, the flow stabilizer fan 1 can overcome this tendency and rotate. This tendency is provided by the maintaining mechanism 12, which continuously provides a force to the flow stabilizer fan 1 in the opposite direction to the water flow, so that the flow stabilizer fan 1 can maintain its minimum angle. The maintaining mechanism 12 is made of an elastic element. According to the characteristics of the elastic element, the greater the force it receives, the greater its self-restoring force. This characteristic means that the greater the water flow, the greater the rotation angle of the flow stabilizer fan 1. The elastic element's restoring force after being further compressed by the rotation of the flow stabilizer fan 1 is greater and balances the impact force of the water flow, so that the flow stabilizer fan 1 can maintain a specific angle.

[0065] In other embodiments, the maintaining mechanism 12 may also employ other technical means, such as magnetism, to continuously provide restoring force and adapt the magnitude of the restoring force to the movement of the constant flow fan 1. Its principle is consistent with the elastic element of this embodiment.

[0066] like Figures 1 to 3As shown, the flow stabilizing valve also includes a valve seat 3 and a flow stabilizing plug 2. The valve seat 3 is disposed in the valve cavity 5 and divides the valve cavity 5 into a first cavity and a second cavity. The valve seat 3 also includes a through hole 31, through which the first cavity and the second cavity are connected. The flow stabilizing plug 2 passes through the through hole 31. The first end of the flow stabilizing plug 2 along the water flow direction is fixed to the flow stabilizing fan 1 in the first cavity. When the flow stabilizing fan 1 is at its maximum angle, the flow stabilizing plug 2 can move from the first position to the second position along the water flow direction under the action of the water flow. In the first position, the through hole 31 is open, and in the second position, the flow stabilizing plug 2 closes the through hole 31.

[0067] In this embodiment, the valve seat 3 is disposed perpendicular to the water flow direction within the valve cavity 5 and perpendicular to the water flow direction within the valve cavity 5. The flow stabilizer 2 is fitted into and fixed within the through hole 31 of the valve seat 3. The flow stabilizer 2 is configured to move only when the flow stabilizer fan 1 is at its maximum angle, its contact area with the water flow is at its maximum, and the water flow impact force is at its maximum.

[0068] In this embodiment, the flow stabilizing valve is also provided with a valve seat 3 and a flow stabilizing plug 2. The flow stabilizing plug 2 can be pushed by the water flow impacting the flow stabilizing fan 1 when the flow stabilizing fan 1 has rotated to its maximum angle, and close the valve seat 3. This achieves the water flow cut-off and water circuit protection when the water flow is too rapid, the water flow rate is too large, the water pressure is too large, and the flow stabilizing fan 1 has reached its maximum angle and can no longer stabilize the flow.

[0069] like Figures 1 to 5 As shown, the flow regulator also includes an elastic reset member 4, which abuts against the flow regulator 2 at the first end and keeps it in the first position.

[0070] In this embodiment, the preload of the elastic element is the same as the force required for the water flow to push the flow stabilizer fan 1 to its maximum angle.

[0071] In this embodiment, the flow stabilizer 2 is reset by the elastic reset member 4 and a pre-tightening force is applied to keep it in the first position, which makes the water flow more stable. When the force is less than the pre-tightening force, the flow stabilizer 2 does not move and thus does not interfere with the water flow, ensuring normal water use for the user.

[0072] like Figures 1 to 3 As shown, the elastic reset member 4 is disposed in the second cavity and abuts against the second end of the flow stabilizer 2;

[0073] The second end of the flow stabilizer 2 extends toward the wall of the valve cavity 5 to form a protrusion 22. When the flow stabilizer 2 is in the first position, the protrusion 22 abuts against the side of the through hole 31 of the valve seat 3 facing the second cavity and restricts the flow stabilizer 2 from moving toward the first cavity.

[0074] In this embodiment, the elastic reset member 4 is disposed in the second cavity and is used to push the flow stabilizer 2 to move to the first position when the water flow is small and the water pressure is low. At the same time, the convex edge 22 limits the flow stabilizer 2 to prevent it from coming out of the through hole 31.

[0075] like Figures 1 to 5 As shown, the second cavity is also provided with an elastic element mounting seat 41, and the elastic element mounting seat 41 is provided with an annular groove 411. One end of the elastic reset member 4 is stuck in the annular groove 411 and abuts against the elastic element mounting seat 41.

[0076] In this embodiment, the elastic reset member 4 can be better fixed through the annular groove 411.

[0077] like Figure 5 As shown, the inner wall of the valve chamber 5 of the flow stabilizing valve is also provided with a sliding groove 13 arranged along the water flow direction, and the rotating shaft 11 of the flow stabilizing fan 1 is arranged in the sliding groove 13.

[0078] In this embodiment, the rotating shaft 11 of the flow stabilizer fan 1 is fixed in the slide groove 13 to achieve synchronous movement with the flow stabilizer plug 2. The slide groove 13 guides and limits its movement, making the fixation effect of the flow stabilizer fan 1 better.

[0079] like Figure 5 As shown, the flow stabilizer 2 is hollow inside. The first end of the flow stabilizer 2 is circumferentially provided with an inlet 21, and the second end of the flow stabilizer 2 is provided with an outlet. The flow stabilizer 2 is hollow inside and connects the inlet 21 and the outlet.

[0080] In the first position, the inlet 21 protrudes from the valve seat 3;

[0081] In the second position, the inlet 21 is closed by the valve seat 3.

[0082] In this embodiment, the flow stabilizer 2 is a hollow structure with an opening at each end for water flow. The inlet 21 located in the first cavity is open in the first position to allow water flow, while it is closed by the valve seat 3 in the second position to cut off the water flow.

[0083] like Figures 1 to 3 As shown, a limiting post 14 is also provided in the valve cavity 5. The limiting post 14 is located on the side of the flow stabilizer fan 1 in the opposite direction to the water flow direction. The limiting post 14 is set on the rotation path of the flow stabilizer fan 1 and limits the flow stabilizer fan 1 to the minimum angle.

[0084] In this embodiment, by setting a limiting post 14 to block the flow stabilizer fan 1, the angle of rotation of the flow stabilizer fan 1 under the reset action can be prevented from being too small, thus causing it to lose its flow stabilization effect. The limiting post 14 can limit its rotation, keeping it at the minimum angle under low voltage conditions, thereby improving the flow stabilization effect.

[0085] like Figures 1 to 3 As shown, there are two constant current fans 1, which are symmetrically arranged along the rotating shaft 11.

[0086] In other embodiments, only one or more may be set.

[0087] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
