Description

Technical Field

[0001] The utility model relates to a flow stabilizing valve and a water heater. Background Art

[0002] In the existing gas water heater water circuit, the water flow rate at the water input end is usually not stable enough, resulting in unstable water flow rate at the output user end, which in turn causes the water temperature to fluctuate, affecting user use. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the defect that the water flow rate at the user end of the gas water heater in the prior art is not stable enough, and to provide a flow stabilizing valve and a water heater.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0005] A flow stabilizing valve, comprising an upper cover and a lower cover, wherein the upper cover is provided with a boss, and the lower cover is provided with a matching hole that matches the boss and penetrates the lower cover, and the flow stabilizing valve further comprises an elastic member, and the elastic member can provide an elastic force for the upper cover to be away from the lower cover;

[0006] When the upper cover overcomes the elastic force provided by the elastic member under the action of the water flow pressure, moves toward the lower cover, and drives the boss to move to the initial position, an initial water flow gap is formed between the inner wall of the matching hole and the outer wall of the boss;

[0007] The flow stabilizing valve further includes a coil and a magnet. The position of the coil corresponds to the position of the magnet. The coil and the magnet cooperate to adjust the size of the initial gap of the water flow.

[0008] The technical solution provides a flow-stabilizing valve, which includes an upper cover and a lower cover, wherein the upper cover is provided with a boss, and the lower cover is provided with a matching hole that matches the boss and penetrates the lower cover. When the flow-stabilizing valve is installed in a waterway, water flows from the upper cover through the inner wall of the matching hole and the outer wall of the boss: when the size between the inner wall of the matching hole and the outer wall of the boss increases, the water flow regulated by the flow-stabilizing valve increases; when the size between the inner wall of the matching hole and the outer wall of the boss decreases, the water flow regulated by the flow-stabilizing valve decreases.

[0009] The flow stabilizing valve further comprises an elastic member, which can provide an elastic force for the upper cover to move away from the lower cover.

[0010] When the upper cover overcomes the elastic force provided by the elastic member under the action of the water flow pressure, moves toward the lower cover, and drives the boss to move to the initial position, an initial water flow gap is formed between the inner wall of the matching hole and the outer wall of the boss. At this time, the elastic force and the water flow pressure are balanced, so that the boss is stable in the initial position.

[0011] The flow stabilizing valve also includes a coil and a magnet. The position of the coil corresponds to the position of the magnet. The coil and the magnet are used together to adjust the size of the initial gap of the water flow: when the water flow rate regulated by the flow stabilizing valve is appropriate, no electromagnetic force is generated between the coil and the magnet; when the water flow rate regulated by the flow stabilizing valve is relatively small, the upper cover moves away from the lower cover under the action of the electromagnetic force, and the size of the initial gap of the water flow is adjusted to a larger size until it stabilizes at a size that makes the water flow rate appropriate; when the water flow rate regulated by the flow stabilizing valve is relatively large, the upper cover moves toward the lower cover under the action of the electromagnetic force, and the size of the initial gap of the water flow is adjusted to a smaller size until it stabilizes at a size that makes the water flow rate appropriate.

[0012] Preferably, when the polarity generated by the end of the coil close to the magnet is opposite to the polarity of the end of the magnet close to the coil, the magnet moves in the direction close to the coil to reduce the size of the initial gap of the water flow, and the magnitude of the suction force generated between the coil and the magnet is positively correlated with the magnitude of the reduction in the size of the initial gap of the water flow;

[0013] When the polarity generated by one end of the coil close to the magnet is the same as the polarity of the end of the magnet close to the coil, the magnet moves away from the coil to increase the size of the initial gap of the water flow, and the magnitude of the repulsive force generated between the coil and the magnet is positively correlated with the magnitude of the increase in the size of the initial gap of the water flow.

[0014] In the present technical solution, through the above arrangement, the electromagnetic force generated between the coil and the magnet can be used to conveniently adjust the size of the initial gap of the water flow with a relatively simple structure.

[0015] Preferably, the outer wall of the boss is inclined, and the cross section of the boss away from the lower cover is larger than the cross section of the boss close to the lower cover.

[0016] In the present technical solution, by setting the outer wall of the boss to be inclined, the cross-section of the boss away from the lower cover is larger than the cross-section of the boss close to the lower cover. When the boss is close to or away from the matching hole, the size change of the initial gap of the water flow is more uniform than other boss structure settings, which can better avoid sudden changes in water flow.

[0017] Preferably, the coil is connected to the lower cover, and the magnet is connected to the upper cover. Alternatively, the coil is connected to the upper cover, and the magnet is connected to the lower cover.

[0018] In the technical solution, through the above arrangement, the electromagnetic force between the coil and the magnet can be used to conveniently adjust the size of the initial gap of the water flow with a relatively simple structure.

[0019] Preferably, the coil disk is arranged at the outer edge of the lower cover, the magnet is arranged at the outer edge of the upper cover, and the outer edge of the lower cover is arranged correspondingly to the outer edge of the upper cover. Alternatively, the coil disk is arranged at the outer edge of the upper cover, the magnet is arranged at the outer edge of the lower cover, and the outer edge of the lower cover is arranged correspondingly to the outer edge of the upper cover.

[0020] In the technical solution, through the above arrangement, the upper cover can be moved by a uniform electromagnetic force with a relatively simple structure, thereby reducing the possibility of deformation of the upper cover due to internal stress.

[0021] Preferably, the elastic member is disposed between the coil and the magnet.

[0022] In the present technical solution, through the above arrangement, the upper cover can be kept balanced by the uniform elastic force, electromagnetic force and water flow pressure with a relatively simple structure, thereby reducing the possibility of deformation of the upper cover due to internal stress.

[0023] Preferably, the lower cover comprises a bracket, the upper cover comprises a stabilizing portion, and the stabilizing portion is connected to the bracket.

[0024] In the technical solution, by arranging the stabilizing portion of the upper cover to be connected to the bracket of the lower cover, it is possible to prevent the upper cover from being offset during movement, thereby affecting the use.

[0025] Preferably, a plurality of the brackets are arranged at intervals along the circumference of the lower cover.

[0026] In the technical solution, by arranging a plurality of brackets at intervals along the circumference of the lower cover, the upper cover can be prevented from being deflected in all directions with a relatively simple structure.

[0027] Preferably, the bracket has a slide groove, and the stabilizing portion is slidably disposed in the slide groove.

[0028] In the technical solution, by arranging the stabilizing portion to be slidably disposed in the slide groove on the bracket, a relatively simple structure can further play a guiding role in the movement process of the upper cover.

[0029] A water heater comprises a flow stabilizing valve as described in any one of the above items, wherein the flow stabilizing valve is arranged in a water path of the water heater.

[0030] The technical solution also provides a water heater, wherein the above-mentioned flow stabilizing valve is arranged in the water path of the water heater, so that the water flow rate output from the water heater to the user end is stable.

[0031] The positive and progressive effects of the utility model are:

[0032] The technical solution provides a flow-stabilizing valve and a water heater, wherein the flow-stabilizing valve is installed in the water circuit of the water heater. The flow-stabilizing valve comprises an upper cover and a lower cover, wherein the upper cover is provided with a boss, and the lower cover is provided with a matching hole that matches the boss and penetrates the lower cover. When the flow-stabilizing valve is installed in the water circuit, the water flows from the upper cover direction through the inner wall of the matching hole and the outer wall of the boss: when the size between the inner wall of the matching hole and the outer wall of the boss increases, the water flow regulated by the flow-stabilizing valve increases; when the size between the inner wall of the matching hole and the outer wall of the boss decreases, the water flow regulated by the flow-stabilizing valve decreases. The flow-stabilizing valve also comprises an elastic member, which can provide an elastic force to the upper cover away from the lower cover. When the upper cover overcomes the elastic force provided by the elastic member under the action of the water flow pressure, moves toward the lower cover, and drives the boss to move to the initial position, an initial water flow gap is formed between the inner wall of the matching hole and the outer wall of the boss. At this time, the elastic force is balanced with the water flow pressure, so that the boss is stable in the initial position. The flow stabilizing valve also includes a coil and a magnet. The position of the coil corresponds to the position of the magnet. The coil and the magnet are used together to adjust the size of the initial gap of the water flow: when the water flow rate regulated by the flow stabilizing valve is appropriate, no electromagnetic force is generated between the coil and the magnet; when the water flow rate regulated by the flow stabilizing valve is relatively small, the upper cover moves away from the lower cover under the action of the electromagnetic force, and the size of the initial gap of the water flow is adjusted to a larger size until it stabilizes at a size that makes the water flow rate appropriate; when the water flow rate regulated by the flow stabilizing valve is relatively large, the upper cover moves toward the lower cover under the action of the electromagnetic force, and the size of the initial gap of the water flow is adjusted to a smaller size until it stabilizes at a size that makes the water flow rate appropriate.

[0049] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0050] like Figure 1-Figure 2 As shown, this embodiment provides a flow stabilizing valve, which includes an upper cover 1 and a lower cover 2. The upper cover 1 is provided with a boss 11, and the lower cover 2 is provided with a matching hole 21 that penetrates the lower cover 2 and matches with the boss 11. The flow stabilizing valve also includes an elastic member 4, which can provide an elastic force to keep the upper cover 1 away from the lower cover 2.

[0051] When the upper cover 1 overcomes the elastic force provided by the elastic member 4 under the action of water flow pressure, moves toward the lower cover 2, and drives the boss 11 to move to the initial position 110, an initial water flow gap 3 is formed between the inner wall of the matching hole 21 and the outer wall of the boss 11.

[0052] The flow stabilizing valve further comprises a coil 5 and a magnet 6. The position of the coil 5 corresponds to the position of the magnet 6. The coil 5 and the magnet 6 cooperate to adjust the size of the initial gap 3 of the water flow.

[0053] In this way, by providing a steady flow valve, when the steady flow valve is installed in the water channel, the water flows from the upper cover 1 through the steady flow hole 13 and enters between the inner wall of the matching hole 21 and the outer wall of the boss 11: when the size between the inner wall of the matching hole 21 and the outer wall of the boss 11 becomes larger, the water flow regulated by the steady flow valve becomes larger; when the size between the inner wall of the matching hole 21 and the outer wall of the boss 11 becomes smaller, the water flow regulated by the steady flow valve becomes smaller.

[0054] The flow stabilizing valve further comprises an elastic member 4 , which can provide an elastic force for the upper cover 1 to move away from the lower cover 2 .

[0055] When the water circuit starts to operate, the upper cover 1 overcomes the elastic force provided by the elastic member 4 under the action of the water flow pressure, moves toward the lower cover 2, and drives the boss 11 to move to the initial position 110, and an initial water flow gap 3 is formed between the inner wall of the matching hole 21 and the outer wall of the boss 11. At this time, the elastic force and the water flow pressure are balanced, so that the boss 11 is stabilized at the initial position 110, and the water flow rate regulated by the flow stabilizing valve is A.

[0056] The water flow rate required by the user end is B, and B is determined according to the water temperature and flow rate used by the user end. This process belongs to the prior art in this field.

[0057] The flow stabilizing valve also includes a coil 5 and a magnet 6. The position of the coil 5 corresponds to the position of the magnet 6. The coil 5 and the magnet 6 cooperate to adjust the size of the initial gap 3 for the water flow: when A=B, no electromagnetic force is generated between the coil 5 and the magnet 6; when A<B, the upper cover 1 moves away from the lower cover 2 under the action of the electromagnetic force, and the size of the initial gap 3 for the water flow is adjusted to a larger size until it stabilizes at a size that makes the water flow rate B; when A>B, the upper cover 1 moves toward the lower cover 2 under the action of the electromagnetic force, and the size of the initial gap 3 for the water flow is adjusted to a smaller size until it stabilizes at a size that makes the water flow rate B.

[0058] When the water flow rate at the subsequent water supply end fluctuates, the coil 5 and the magnet 6 are also adjusted in coordination until the size of the initial gap 3 of the water flow is stabilized and maintained at a size that enables the water flow rate to be B.

[0059] It should be noted that how the coil and the magnet cooperate to adjust the size of the distance between the inner wall of the matching hole and the outer wall of the boss (ie, the water flow gap) also belongs to the prior art in this field.

[0060] In this embodiment, when the polarity generated by the end of the coil 5 close to the magnet 6 is opposite to the polarity of the end of the magnet 6 close to the coil 5, the magnet 6 moves in the direction close to the coil 5 to reduce the size of the initial gap 3 of the water flow, and the magnitude of the suction force generated between the coil 5 and the magnet 6 is positively correlated with the amplitude of reducing the size of the initial gap 3 of the water flow. When the suction force between the coil 5 and the magnet 6 increases, the size of the initial gap 3 of the water flow decreases, and the water flow rate decreases; when the suction force between the coil 5 and the magnet 6 decreases, the size of the initial gap 3 of the water flow increases, and the water flow rate increases; in this case, the maximum value of the size of the initial gap 3 of the water flow corresponds to the maximum value of the water flow rate, and the upper cover 1 is at a position where the elastic force and the water flow pressure are balanced.

[0061] When the polarity generated by the end of the coil 5 close to the magnet 6 is the same as the polarity of the end of the magnet 6 close to the coil 5, the magnet 6 moves away from the coil 5 to increase the size of the initial gap 3 of the water flow, and the magnitude of the repulsive force generated between the coil 5 and the magnet 6 is positively correlated with the amplitude of the increase in the size of the initial gap 3 of the water flow. When the repulsive force between the coil 5 and the magnet 6 increases, the size of the initial gap 3 of the water flow increases, and the water flow rate increases; when the repulsive force between the coil 5 and the magnet 6 decreases, the size of the initial gap 3 of the water flow decreases, and the water flow rate decreases; in this case, the minimum value of the size of the initial gap 3 of the water flow corresponds to the minimum value of the water flow rate, and the upper cover 1 is at a position where the elastic force and the water flow pressure are balanced.

[0062] In this way, by controlling the magnitude and direction of the current in the coil 5 , the magnitude and direction of the electromagnetic force between the coil 5 and the magnet 6 can be adjusted, thereby conveniently adjusting the size of the initial gap 3 of the water flow.

[0063] In this embodiment, the outer wall of the boss 11 is inclined, and the cross section of the boss 11 away from the lower cover 2 is larger than the cross section of the boss 11 close to the lower cover 2 .

[0064] In this way, when the boss 11 approaches or moves away from the matching hole 21, the size change of the initial gap 3 of the water flow is more uniform than that of other boss 11 structural settings, which can better avoid sudden changes in the water flow rate.

[0065] In this embodiment, the coil 5 is connected to the lower cover 2 , and the magnet 6 is connected to the upper cover 1 .

[0066] In this way, the electromagnetic force between the coil 5 and the magnet 6 can conveniently adjust the size of the initial water flow gap 3 with a relatively simple structure. Of course, in other embodiments, the coil 5 can be connected to the upper cover 1 and the magnet 6 can be connected to the lower cover 2.

[0067] In this embodiment, the coil 5 is coiled on the outer edge of the lower cover 2 , the magnet 6 is disposed on the outer edge of the upper cover 1 , and the outer edge of the lower cover 2 and the outer edge of the upper cover 1 are disposed correspondingly.

[0068] In this way, the upper cover 1 can be moved by a uniform electromagnetic force with a relatively simple structure, reducing the possibility of deformation of the upper cover 1 due to internal stress. Of course, in other embodiments, the coil 5 can be arranged at the outer edge of the upper cover 1, and the magnet 6 can be arranged at the outer edge of the lower cover 2, and the outer edge of the lower cover 2 and the outer edge of the upper cover 1 are arranged correspondingly.

[0069] In this embodiment, the elastic member 4 is disposed between the coil 5 and the magnet 6 .

[0070] In this way, the upper cover 1 can be kept balanced by the uniform elastic force, electromagnetic force and water flow pressure with a relatively simple structure, reducing the possibility of deformation of the upper cover 1 due to internal stress. The elastic member 4 in this embodiment is a spring, and the spring coil is arranged on the outer edge of the lower cover 2; in other embodiments, the elastic member 4 can also adopt other structures.

[0071] In this embodiment, the lower cover 2 includes a bracket 22 , and the upper cover 1 includes a stabilizing portion 12 , and the stabilizing portion 12 is connected to the bracket 22 .

[0072] In this way, by arranging the stabilizing portion 12 of the upper cover 1 to be connected to the bracket 22 of the lower cover 2, it is possible to prevent the upper cover 1 from being deviated during the movement process, thereby affecting the use.

[0073] In this embodiment, a plurality of brackets 22 are arranged at intervals along the circumference of the lower cover 2 .

[0074] In this way, the upper cover 1 can be prevented from deflecting in all directions with a relatively simple structure. Furthermore, in this embodiment, a plurality of brackets 22 are arranged equidistantly along the circumference of the lower cover 2, reducing the possibility of deformation of the upper cover 1 due to internal stress generated by uneven force.

[0075] In this embodiment, the bracket 22 has a sliding groove 221 , and the stabilizing portion 12 is slidably disposed in the sliding groove 221 .

[0076] In the present technical solution, by arranging the stabilizing portion 12 to be slidably disposed in the slide groove 221 on the bracket 22 , a relatively simple structure can further play a guiding role in the movement process of the upper cover 1 .

[0077] This embodiment also provides a water heater, which includes a flow stabilizing valve as described in any of the above items, and the flow stabilizing valve is arranged in the water path of the water heater to stabilize the water flow output from the water heater to the user end.

Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
