Description

Technical Field

[0001] The present invention relates to the field of water heaters, and in particular to a flow stabilizing valve and a water heater comprising the same. Background Art

[0002] As gas water heaters gain increasing market share, more and more problems are emerging. For example, the water flow in users' homes is unstable. If the water flow entering the water heater fluctuates or the water pressure is too high, it will bring a very bad user experience. For example, water flow fluctuations can cause the water outlet of the water heater to fluctuate between hot and cold. Excessive water pressure can cause components to rupture, causing personal injury and property damage to users. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defects in the prior art that the fluctuation of water flow entering the water heater may cause the water outlet of the water heater to be hot and cold, and that excessive water pressure may cause the components to rupture, and provide a flow stabilizing valve and a water heater containing the same.

[0004] The present invention solves the above technical problems through the following technical solutions:

[0005] A flow stabilizing valve is characterized in that it comprises:

[0006] steady flow shell;

[0007] A flow stabilizing seat, the flow stabilizing seat being located in the flow stabilizing shell and being coaxially arranged with the flow stabilizing shell;

[0008] A flow stabilizing plug, wherein a first end of the flow stabilizing plug along the axial direction of the flow stabilizing shell is provided through the flow stabilizing seat, and a second end of the flow stabilizing plug is provided through the flow stabilizing shell, a flow channel is provided in the flow stabilizing plug along the axial direction, and a liquid outlet is provided at the top of the second end of the flow stabilizing plug in the radial direction, the outlet being connected to the flow channel and exposed to the flow stabilizing shell;

[0009] a transmission component, the transmission component being inserted into the flow stabilizing plug along a transmission direction, with an outer edge of the transmission component abutting against the flow stabilizing seat, and the transmission direction forming an angle greater than 0 degrees and less than or equal to 90 degrees with the axial direction;

[0010] In which, the flow stabilizer seat can leave the initial position under the action of water pressure and move relative to the flow stabilizer shell along the positive direction of the axial direction, drive the transmission component to move in the positive direction of the transmission direction, and drive the flow stabilizer plug to move in the reverse direction of the axial direction relative to the flow stabilizer shell, so that the flow stabilizer shell blocks the liquid outlet and reduces the liquid outlet area of the liquid outlet; after the flow stabilizer seat leaves the initial position, the flow stabilizer seat can move relative to the flow stabilizer shell along the reverse direction of the axial direction under the action of the restoring force, drive the transmission component to move in the reverse direction of the transmission direction, and drive the flow stabilizer plug to move in the positive direction of the axial direction relative to the flow stabilizer shell, so that the flow stabilizer shell leaves the liquid outlet and restores the liquid outlet area of the liquid outlet.

[0011] When the water flow is lower than the steady pressure point, the flow stabilizer seat is in the initial position, that is, when the user has no water demand or the water flow is lower than the steady pressure point, the flow stabilizer seat is in the initial position under the action of the preload force (restoring force). At this time, the liquid (cold water) can flow out from the flow channel in the flow stabilizer plug through the liquid outlet; when the water flow is higher than the steady pressure point, the flow stabilizer seat leaves the initial position under the action of the water pressure and moves axially in the positive direction relative to the flow stabilizer shell, drives the transmission component to move in the transmission direction, and drives the flow stabilizer plug to move axially in the reverse direction relative to the flow stabilizer shell, so that the flow stabilizer shell blocks the liquid outlet and reduces the liquid outlet area of the liquid outlet; after the flow stabilizer seat leaves the initial position, and the water flow is lower than the steady pressure point, the flow stabilizer seat can move axially in the reverse direction relative to the flow stabilizer shell under the action of the restoring force, drives the transmission component to move in the reverse direction along the transmission direction, and drives the flow stabilizer plug to move axially in the positive direction relative to the flow stabilizer shell, so that the flow stabilizer shell leaves the liquid outlet, restores the liquid outlet area of the liquid outlet, and finally returns to the initial position. The coordination of the flow stabilizer, transmission components, flow stabilizer plug, and flow stabilizer housing ensures that the water flow rate does not increase, maintaining the flow rate at the steady flow point. This prevents fluctuations in water flow entering the water heater, which can cause the water outlet to fluctuate, and prevents excessive water pressure from causing component rupture. This flow stabilizer valve utilizes a purely mechanical structure, requiring no energy consumption. It is compact, consumes no power, and has a simple structure, allowing for easy and feasible installation, regardless of installation direction.

[0012] Preferably, the outer periphery of the transmission component has a first inclined surface, and the flow stabilizer seat has a second inclined surface that can be in contact with the first inclined surface. Under the action of water pressure, the second inclined surface of the flow stabilizer seat pushes the first inclined surface to cause the transmission component to move in the positive direction of the transmission direction.

[0013] The outer periphery of the transmission component also has a third inclined surface, which is arranged parallel to the first inclined surface. The flow stabilizer seat also has a fourth inclined surface that can be in contact with the third inclined surface. Under the action of the restoring force, the fourth inclined surface of the flow stabilizer seat pushes the third inclined surface to cause the transmission component to move in the opposite direction of the transmission direction.

[0014] In this technical solution, the second inclined surface of the flow stabilizer seat pushes the first inclined surface of the transmission component to make the transmission component move in the positive direction of the transmission direction, and the fourth inclined surface of the flow stabilizer seat pushes the third inclined surface of the transmission component to make the transmission component move in the reverse direction of the transmission direction, so that the axial movement of the flow stabilizer seat is converted into the movement of the transmission component along the transmission direction; and the surface contact can ensure smoother movement.

[0019] In this technical solution, a specific arrangement of the flow stabilizer is provided through the above arrangement.

[0020] Preferably, the flow stabilizing valve also includes an elastic structural member, one end of which abuts against the bottom wall of the flow stabilizing seat, and the other end abuts against the limit platform on the flow stabilizing plug, and the elastic structural member applies the restoring force to the flow stabilizing seat to make the flow stabilizing seat located in the initial position.

[0021] In this technical solution, an elastic structural member is provided to apply a restoring force to the flow stabilizer seat so that the flow stabilizer seat is located in the initial position or returns to the initial position, that is, the flow stabilizer seat is in the initial position or returns to the initial position under the action of the preload force (restoring force) applied by the elastic structural member.

[0022] Preferably, the elastic structural member is a spring; a boss is provided on a surface of the bottom wall of the flow stabilizing seat facing the elastic structural member, the spring is sleeved outside the flow stabilizing plug, and the spring is sleeved outside the boss.

[0023] In this technical solution, a specific embodiment of an elastic structural member is provided through the above-mentioned arrangement. Furthermore, a boss is provided to limit the spring.

[0024] Preferably, a limit card is provided at the first end of the flow stabilizer bolt, the fixed end of the limit card is connected to the flow stabilizer bolt, and the free end extends in the direction away from the flow stabilizer bolt. When the flow stabilizer seat is in the initial position, the limit card is located in the flow stabilizer seat; when the limit card is exposed from the flow stabilizer seat, the free end of the limit card is clamped on the outer wall surface of the flow stabilizer seat to limit the axial movement of the flow stabilizer seat.

[0025] In the present technical solution, a limit card is provided to limit the axial movement of the flow stabilizing seat, thereby preventing unnecessary losses caused by continued water flow due to a decrease in water pressure after the rupture.

[0026] Preferably, a mounting tube is provided in the flow stabilizing shell, a first mounting hole is provided in the mounting tube and passes through the mounting tube along the axis, and the second end of the flow stabilizing plug is passed through the first mounting hole;

[0078] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0079] like Figures 1 to 7 As shown, this embodiment provides a flow stabilizing valve 1 , which includes: a flow stabilizing shell 10 , a flow stabilizing seat 20 , a flow stabilizing plug 30 and a transmission component 40 .

[0080] The flow stabilizer seat 20 is located within the flow stabilizer shell 10 and is coaxially arranged with the flow stabilizer shell 10. The flow stabilizer plug 30 has a first end 31 extending through the flow stabilizer seat 20 along the axial direction O of the flow stabilizer shell 10, and a second end 32 extending through the flow stabilizer shell 10. A flow channel 60 is defined within the flow stabilizer plug 30 along the axial direction O, and a liquid outlet 33 is radially defined at the top of the second end 32 of the flow stabilizer plug 30, communicating with the flow channel 60 and exposed to the flow stabilizer shell 10. A transmission component 40 extends through the flow stabilizer plug 30 along a transmission direction P, and the outer edge of the transmission component 40 abuts against the flow stabilizer seat 20. The transmission direction P forms an angle α of 90 degrees with the axial direction O (i.e., the transmission direction P is perpendicular to the axial direction O). Among them, the flow stabilizer seat 20 can leave the initial position under the action of water pressure and move relative to the flow stabilizer shell 10 along the positive direction of the axial direction O, drive the transmission component 40 to move along the positive direction of the transmission direction P, and drive the flow stabilizer plug 30 to move relative to the flow stabilizer shell 10 along the reverse direction of the axial direction O, so that the flow stabilizer shell 10 blocks the liquid outlet 33 and reduces the liquid outlet area of the liquid outlet 33; after the flow stabilizer seat 20 leaves the initial position, the flow stabilizer seat 20 can move relative to the flow stabilizer shell 10 along the reverse direction of the axial direction O under the action of the restoring force, drive the transmission component 40 to move along the reverse direction of the transmission direction P, and drive the flow stabilizer plug 30 to move relative to the flow stabilizer shell 10 along the positive direction of the axial direction O, so that the flow stabilizer shell 10 leaves the liquid outlet 33 and restores the liquid outlet area of the liquid outlet 33.

[0081] In this way, when the flow stabilizing seat 20 of the flow stabilizing valve 1 is in the initial position, that is, when the user has no water demand or the water flow is lower than the flow stabilizing point, the flow stabilizing seat 20 is in the initial position under the action of the preload force (restoring force). At this time, the liquid (cold water) can flow out from the flow channel 60 in the flow stabilizing plug 30 through the liquid outlet 33; when the water flow is higher than the pressure stabilizing point, the flow stabilizing seat 20 leaves the initial position under the action of the water pressure and moves forward along the axial direction O relative to the flow stabilizing shell 10, driving the transmission component 40 to move along the transmission direction P, driving the flow stabilizing plug 30 to move axially relative to the flow stabilizing shell 10 O moves in the opposite direction so that the flow stabilizing shell 10 blocks the liquid outlet 33 and reduces the liquid outlet area of the liquid outlet 33; after the flow stabilizing seat 20 leaves the initial position and the water flow rate is lower than the stabilizing pressure point, the flow stabilizing seat 20 can move in the opposite direction of the axial direction O relative to the flow stabilizing shell 10 under the action of the restoring force, driving the transmission component 40 to move in the opposite direction of the transmission direction P, driving the flow stabilizing plug 30 to move in the positive direction of the axial direction O relative to the flow stabilizing shell 10, so that the flow stabilizing shell 10 leaves the liquid outlet 33, restores the liquid outlet area of the liquid outlet 33, and finally returns the flow stabilizing seat 20 to the initial position. The coordination of the flow stabilizing seat 20, the transmission component 40, the flow stabilizing plug 30 and the flow stabilizing shell 10 ensures that the water flow rate will not increase and maintain the flow rate size of the stabilizing point, thereby avoiding the phenomenon of the water outlet of the water heater being hot and cold due to fluctuations in the water flow entering the water heater and the expansion and cracking of components due to excessive water pressure. The flow stabilizing valve 1 adopts a purely mechanical structure and does not require any energy loss; the flow stabilizing valve 1 is small in size, consumes no power, has a simple structure, is easy and feasible to install, and is not restricted by the installation direction.

[0082] It should be noted that the angle α formed between the transmission direction P and the axial direction O can be any angle greater than 0 degrees and less than or equal to 90 degrees, as long as it can ultimately drive the flow stabilizer 30 to move in the opposite direction of the axial direction O relative to the flow stabilizer shell 10. Optimally, the angle α formed between the transmission direction P and the axial direction O is equal to 90 degrees. Under this angle, the movement of the transmission component 40 along the transmission direction P is more convenient, the loss of forces in other directions can be reduced, and the overall structure is more compact. The positive direction of the axial direction O and the reverse direction of the axial direction O are two opposite directions along the axial direction O; the positive direction of the transmission direction P and the reverse direction of the transmission direction P are two opposite directions along the transmission direction P.

[0083] In this embodiment, the flow stabilizer 30 is also arranged along the axial direction O, but this is not limited to this. In other embodiments, the flow stabilizer 30 can be arranged along other directions. In this embodiment, the number of liquid outlets 33 at the top of the second end 32 of the flow stabilizer 30 is four. However, this is not limiting. In other embodiments, the number of liquid outlets 33 can also be other numbers, such as one, two, three, or five. The liquid outlets 33 are radially disposed on the flow stabilizer 30, where radial refers to the radial direction of the flow stabilizer shell 10.

[0084] The four liquid outlets 33 are spaced apart along the circumference of the flow stabilizer 30. Preferably, the intervals between adjacent liquid outlets 33 are the same, so that the liquid can flow out of the liquid outlets 33 more evenly.

[0085] In this embodiment, the outer periphery of the transmission component 40 has a first inclined surface 421, and the flow stabilizer seat 20 has a second inclined surface 221 that can be aligned with the first inclined surface 421. Under the action of water pressure, the second inclined surface 221 of the flow stabilizer seat 20 pushes the first inclined surface 421, causing the transmission component 40 to move in the positive direction of the transmission direction P. The outer periphery of the transmission component 40 also has a third inclined surface 431, which is arranged parallel to the first inclined surface 421. The flow stabilizer seat 20 also has a fourth inclined surface 222 that can be aligned with the third inclined surface 431. Under the action of a restoring force, the fourth inclined surface 222 of the flow stabilizer seat 20 pushes the third inclined surface 431, causing the transmission component 40 to move in the reverse direction of the transmission direction P. In this way, the second inclined surface 221 of the flow stabilizer seat 20 pushes the first inclined surface 421 of the transmission component 40 to move the transmission component 40 along the transmission direction P, and the fourth inclined surface 222 of the flow stabilizer seat 20 pushes the third inclined surface 431 of the transmission component 40 to move the transmission component 40 in the opposite direction of the transmission direction P, so that the movement of the flow stabilizer seat 20 along the axial direction O is converted into the movement of the transmission component 40 along the transmission direction P; and the surface contact can ensure smoother movement. It should be noted that because the third inclined surface 431 is arranged parallel to the first inclined surface 421, the second inclined surface 221 is aligned with the first inclined surface 421, and the fourth inclined surface 222 is aligned with the third inclined surface 431, and thus the second inclined surface 221 is also parallel to the fourth inclined surface 222, by sandwiching the first inclined surface 421 and the third inclined surface 431 of the transmission component 40 between the second inclined surface 221 and the fourth inclined surface 222 of the flow stabilizer seat 20, the movement of the transmission component 40 can be limited, thereby ensuring that the transmission component 40 can move smoothly along the predetermined route. The inclination angles of the first inclined surface 421, the second inclined surface 221, the third inclined surface 431, and the fourth inclined surface 222 can be adjusted according to design requirements.

[0086] It should be noted that the present embodiment achieves displacement conversion in different motion directions by providing a transmission component 40, which is different from conventional technical means in the art. In this technical field, displacement conversion in different directions is generally performed through gears. When displacement conversion in different directions is performed through gears, the area of the liquid outlet 33 is adjusted by at least the pitch of one tooth (a certain spacing adjustment). However, in this embodiment, the displacement conversion in different motion directions of the second inclined surface 221 and the first inclined surface 421 are bonded, and the displacement conversion in different motion directions of the fourth inclined surface 222 and the third inclined surface 431 are bonded (displacement conversion method of different motion directions of inclined surfaces). Compared with the gear conversion method, the area of the liquid outlet 33 is adjusted more smoothly (without spacing adjustment), and has a more excellent technical effect of adjusting the water flow rate.

[0087] Specifically, the transmission component 40 includes a middle portion 41 inserted into the flow stabilizer 30, and a first end portion 42 and a second end portion 43 located at opposite ends of the middle portion 41 along the transmission direction P and both located outside the flow stabilizer 30. The middle portion 41 extends obliquely, and a first inclined surface 421 is provided on the outside of the first end portion 42. The cross-section of the middle portion 41 of the flow stabilizer 30 is rectangular, but is not limited thereto and may also be other shapes such as a circle.

[0088] Furthermore, a third inclined surface 431 is provided on the outer side of the second end portion 43 of the transmission component 40. The third inclined surface 431 is arranged parallel to the first inclined surface 421. The flow stabilizer seat 20 has a fourth inclined surface 222 that can mate with the third inclined surface 431. Thus, the third inclined surface 431 of the transmission component 40 and the fourth inclined surface 222 of the flow stabilizer seat 20 that cooperate therewith limit the movement of the transmission component 40, thereby ensuring that the transmission component 40 can move smoothly along the predetermined route.

[0089] The flow stabilizer seat 20 includes a bottom wall and a side wall arranged around the bottom wall. The bottom wall 21 of the flow stabilizer seat is arranged in a direction perpendicular to the axial direction O, and the side of the bottom wall 21 of the flow stabilizer seat facing the water flow is a pressure surface 211. A through hole 212 is provided on the bottom wall 21 of the flow stabilizer seat, and the first end 31 of the flow stabilizer plug 30 is passed through the through hole 212 on the bottom wall 21 of the flow stabilizer seat. The side wall 22 of the flow stabilizer seat is provided with a second inclined surface 221 at a position corresponding to the first inclined surface 421 of the first end portion 42 of the transmission component 40. The side wall 22 of the flow stabilizer seat is provided with a fourth inclined surface 222 at a position corresponding to the third inclined surface 431 of the first end portion 42 of the transmission component 40. The outer wall surface of the side wall 22 of the flow stabilizer seat abuts against the inner wall surface of the side wall of the flow stabilizer shell 10.

[0090] In this embodiment, the flow stabilizing valve 1 further includes an elastic structural member, one end of which abuts against the bottom wall 21 of the flow stabilizing seat, and the other end abuts against the limit platform 34 on the flow stabilizing plug 30. The elastic structural member applies a restoring force to the flow stabilizing seat 20 to keep the flow stabilizing seat 20 in its initial position. In this way, by providing the elastic structural member to apply a restoring force to the flow stabilizing seat 20 to keep the flow stabilizing seat 20 in its initial position or to return it to its initial position, the flow stabilizing seat 20 is in its initial position or to return to its initial position under the action of the preload force (restoring force) applied by the elastic structural member.

[0091] Specifically, the elastic structural member is a spring 50, but is not limited thereto. The elastic structural member may also be other components capable of providing a restoring force to the flow stabilizer seat 20. A boss 23 is provided on the side of the bottom wall 21 of the flow stabilizer seat facing the elastic structural member. The spring 50 is sleeved around the flow stabilizer plug 30 and is sleeved outside the boss 23. Thus, the boss 23 serves to limit the spring 50.

[0092] A limiter clip 35 is provided at the first end 31 of the flow stabilizer 30. The fixed end 351 of the limiter clip 35 is connected to the flow stabilizer 30, while the free end 352 extends away from the flow stabilizer 30. When the flow stabilizer seat 20 is in its initial position, the limiter clip 35 is located within the flow stabilizer seat 20. When the limiter clip 35 is exposed from the flow stabilizer seat 20, the free end 352 of the limiter clip 35 engages the outer wall of the flow stabilizer seat 20, restricting movement of the flow stabilizer seat 20 along the axial direction O. Thus, by providing the limiter clip 35 to restrict movement of the flow stabilizer seat 20 along the axial direction O, it is possible to prevent water from continuing to flow due to reduced water pressure after a rupture, thereby preventing unnecessary losses. When passing through the through hole 212 in the bottom wall 21 of the flow stabilizer seat, the free end 352 of the limiter clip 35 is subjected to pressure from the inner wall of the through hole 212, causing it to deform and pass through the through hole 212. In this embodiment, there are four limiter clips 35. However, the present invention is not limited thereto. In other embodiments, the number of the limiting cards 35 may be other numbers, such as one, two, three, or five, as long as the flow stabilizer seat 20 can be limited to move along the axial direction O. The limiting cards 35 may be integrally formed with the flow stabilizer plug 30, or may be separately manufactured from the flow stabilizer plug 30 and then fixed to the flow stabilizer plug 30. The limiting cards 35 may be made of metal or plastic.

[0093] In this embodiment, four limit cards 35 are spaced apart along the circumference of the flow stabilizer 30. Preferably, the spacing between adjacent limit cards 35 is the same, so as to apply uniform resistance to the flow stabilizer seat 20.

[0094] The stabilizing shell 10 is provided with a mounting tube 11. A first mounting hole 111 is defined within the mounting tube 11, extending along its axis. The second end 32 of the stabilizing plug 30 is inserted into the first mounting hole 111. A second mounting hole 112 is defined in the mounting tube 11, extending along the transmission direction P. The transmission component 40 is inserted into the second mounting hole 112. This specific structure of the mounting tube 11 provides a simple and compact installation method, reducing the overall space occupied by the structure.

[0095] A guide groove 113 extends outward from the outer edge of the mounting tube 11 along the transmission direction P. The guide groove 113 is provided corresponding to the second mounting hole 112, and a portion of the outer edge of the transmission component 40 abuts against the inner wall of the guide groove 113. Thus, by providing the guide groove 113 for guiding the transmission component 40, the transmission component 40 is prevented from deflecting during movement and also serves to limit the position of the transmission component 40.

[0096] The working process of the flow regulating valve 1 of this embodiment is as follows:

[0097] like Figure 8As shown, when the user has no water demand or the water flow rate is lower than the steady flow point, the flow stabilizing seat 20 is in the initial position under the action of the preload force of the spring 50 (elastic structural member). At this time, the liquid (cold water) can flow out from the flow channel 60 in the flow stabilizing plug 30 through the liquid outlet 33. Figure 8 The arrow in the figure indicates the direction of water flow.

[0098] like Figure 9 As shown, when the water flow rate is higher than the pressure stabilization point, the water pressure pushes the flow stabilization seat 20 to overcome the preload force (restoring force) of the spring 50 and move upward (i.e., move in the positive direction along the axial direction O), thereby pushing the transmission component 40 to move in the positive direction of the transmission direction P, thereby driving the flow stabilization plug 30 to move downward (move in the reverse direction along the axial direction O), and the liquid outlet 33 is slowly blocked by the flow stabilization shell 10, reducing the liquid outlet area (flow area) of the liquid outlet 33, ensuring that the water flow rate will not increase, maintaining the flow rate size at the flow stabilization point, and no flow fluctuation will occur under the action of the spring 50. Figure 9 The arrow in the figure indicates the direction of water flow. After the flow stabilizer seat 20 leaves its initial position and the water flow rate falls below the stabilizing pressure point, the flow stabilizer seat 20 can move downward (i.e., move in the opposite direction of the axial direction O) under the restoring force of the spring 50, thereby pushing the transmission component 40 in the opposite direction of the transmission direction P, thereby driving the flow stabilizer plug 30 upward (moving in the positive direction of the axial direction O), so that the flow stabilizer shell 10 moves away from the liquid outlet 33, restoring the liquid outlet area of the liquid outlet 33, and ultimately returning the flow stabilizer seat 20 to its initial position.

[0099] like Figure 10 As shown, when the water pressure is too high, potentially causing a risk of rupture, the water pressure continues to push the flow stabilizer seat 20 upward (i.e., in the positive direction of the axial direction O). Ultimately, the liquid outlet 33 of the flow stabilizer plug 30 is completely blocked by the flow stabilizer shell 10, preventing the water from flowing out. The free end 352 of the limit card 35 on the flow stabilizer plug 30 is stuck on the flow stabilizer seat 20, preventing the water pressure from decreasing after the rupture, thereby continuing to flow water and causing unnecessary losses. After the limit card 35 is stuck on the flow stabilizer seat 20, external intervention is required to reset the limit card 35.

[0100] This embodiment also provides a water heater, comprising the aforementioned flow stabilizing valve 1. The flow stabilizing valve 1 and the water heater of this embodiment can prevent fluctuations in water flow entering the water heater, which can cause the water outlet to fluctuate, and prevent excessive water pressure from causing component rupture. The flow stabilizing valve of this embodiment utilizes a purely mechanical structure, requiring no energy consumption. The flow stabilizing valve of this embodiment is compact, consumes no power, has a simple structure, and is easily and practically installed, with no restrictions on installation orientation.

Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, and such changes and modifications are intended to fall within the scope of the present invention.
