Technical Field
[0001] The utility model relates to a waterway valve, in particular to a waterway valve driven by water pressure. Background Art
[0002] At present, as an accessory for controlling the opening and closing of pipelines, waterway valves have been widely used in the waterway systems of various water dispensers and water purifiers. There are mainly two common control methods for waterway valves. One is to manually operate the switch by a person, and the other is to control the switch through electric drive in cooperation with electric signals, such as solenoid valves. Manual waterway valves are cheap, but they require manual operation by a person and cannot meet the needs of complex waterway systems in the face of the current intelligent trend; while electric control waterway valves can conveniently achieve various control effects through electric drive, but due to the inclusion of precise circuit structures, the price of electric control waterway valves is much higher than that of ordinary valves, and a corresponding circuit control system also needs to be supported, resulting in extremely high deployment costs.
[0003] Therefore, how to overcome the above-mentioned defects has become an important issue that needs to be solved urgently by those skilled in the art. Content of the Utility Model
[0004] The utility model overcomes the above-mentioned technical deficiencies and provides a waterway valve driven by water pressure.

[0006] A waterway valve driven by water pressure includes a magnetically controlled valve body 1. An inlet 2 connected to the water inlet pipeline and an outlet 3 connected to the water outlet pipeline are provided on the magnetically controlled valve body 1. The magnetically controlled valve body 1 is opened and closed according to the strength of the magnetic force it receives. A magnetically controlled component 4 capable of applying magnetic force to it is connected to the magnetically controlled valve body 1. A control water port 5 connected to the control waterway is provided on the magnetically controlled component 4. The magnetically controlled component 4 controls whether to apply strong magnetic force to the magnetically controlled valve body 1 according to the water pressure input from the control water port 5.
[0007] Preferably, the magnetically controlled component 4 includes a sealing cover 41 and a rolling diaphragm 42 arranged between the sealing cover 41 and the magnetically controlled valve body 1.

The control water port 5 is provided on the sealing cover 41 and communicated with the sealing cavity 43. A magnet 44 is fixed on the outer surface of the rolling diaphragm 42 near the magnetically controlled valve body 1.
[0008] Preferably, a guiding column 11 protrudes from the surface of the magnetically controlled valve body 1. Both the rolling diaphragm 42 and the magnet 44 are sleeved on the guiding column 11. A guiding groove 421 is recessed inward from the end surface of the rolling diaphragm 42 near the magnetically controlled valve body 1 to facilitate sleeving on the guiding column 11.
[0009] Preferably, a return spring 45 is provided between the rolling diaphragm 42 and the magnetically controlled valve body 1, and the return spring 45 is used to push the end of the rolling diaphragm 42 close to the magnetically controlled valve body 1 away from the magnetically controlled valve body 1.
[0010] Preferably, the return spring 45 can also be provided between the magnet 44 and the magnetically controlled valve body 1. In this case, the return spring 45 is used to directly push the magnet 44 away from the magnetically controlled valve body 1.

[0020] The features of the present utility model and other related features will be further described in detail through the following embodiments for the understanding of those skilled in the same industry:
[0021] As Figures 1 to 3 shown, a water pressure-driven waterway valve includes a magnetically controlled valve body 1. An inlet 2 connected to the water inlet pipeline and an outlet 3 connected to the water outlet pipeline are provided on the magnetically controlled valve body 1. The magnetically controlled valve body 1 is switched on and off according to the strength of the magnetic force it receives. A magnetically controlled component 4 capable of applying a magnetic force to it is connected to the magnetically controlled valve body 1. A control water port 5 connected to the control waterway is provided on the magnetically controlled component 4. The magnetically controlled component 4 controls whether to apply a strong magnetic force to the magnetically controlled valve body 1 according to the water pressure input at the control water port 5.
[0022] As described above, the waterway valve in this case includes a magnetically controlled valve body 1 and a magnetically controlled component 4. The magnetically controlled valve body 1 controls the on-off of the waterway between the inlet 2 and the outlet 3 according to the strength of the magnetic force it receives, while the magnetically controlled component 4 can control whether to apply a strong magnetic force to the magnetically controlled valve body 1 according to the magnitude of the water pressure at the control water port 5. When using the waterway valve in this case, after connecting the inlet 2 and the outlet 3 to the positions in the waterway that need to be controlled for on-off, only by connecting the control water port 5 to a specific position in the waterway according to the control requirements, the magnetically controlled valve body 1 can control the on-off between the inlet 2 and the outlet 3 according to the water pressure at this specific position. In this way, the waterway valve can achieve automatic control of the waterway on-off without deploying a control circuit and without using expensive electric control valves, thus greatly reducing the deployment cost and deployment difficulty of the waterway control system.
[0023] Specifically, the magnetically controlled valve body 1 has the same on-off structure as a conventional solenoid valve. The difference between the two is that the magnetically controlled valve body 1 in this case does not have an electromagnetic coil for generating magnetic force by itself and does not need to be powered on for use.
[0024] As Figures 2 to 3 shown, preferably, the magnetically controlled component 4 includes a sealing cover 41 and a rolling diaphragm 42 arranged between the sealing cover 41 and the magnetically controlled valve body 1. The open end of the rolling diaphragm 42 is fitted and sealed with the sealing cover 41 to form a sealing cavity 43. The control water port 5 is provided on the sealing cover 41 and is communicated with the sealing cavity 43. A magnet 44 is fixed on the outer surface of the rolling diaphragm 42 near the magnetically controlled valve body 1.
[0025] As described above, when the input water pressure of the control water inlet 5 increases, the water pressure borne by the sealing cavity 43 also increases. In this way, under the influence of the water pressure, the rolling diaphragm 42 will deform and expand, and at the same time drive the magnet 44 closer to the magnet control valve body 1, so that the magnet 44 can apply a stronger magnetic force to the magnet control valve body 1. When the magnet 44 approaches to a certain extent and the magnetic force received by the magnet control valve body 1 reaches a certain threshold, the magnet control valve body 1 will act to cut off the water path. On the contrary, when the input water pressure of the control water inlet 5 decreases, the water pressure borne by the sealing cavity 43 also decreases. In this way, under the influence of the water pressure, the rolling diaphragm 42 will deform and contract, and at the same time drive the magnet 44 away from the magnet control valve body 1, so that the magnetic force applied by the magnet 44 to the magnet control valve body 1 becomes weaker. When the magnet 44 moves away to a certain extent and the magnetic force received by the magnet control valve body 1 reaches a certain threshold, the magnet control valve body 1 will act to connect the water path. In this way, without setting sensors, control circuits, and power drives in the magnet control component 4 of this case, it can also effectively control whether to apply a strong magnetic force to the magnet control valve body 1 according to the water pressure, and then control the on-off of the water path, which can greatly reduce the deployment cost of the water path control system.
[0026] As Figures 2 to 3 shown, preferably, a guiding column 11 protrudes from the surface of the magnet control valve body 1. Both the rolling diaphragm 42 and the magnet 44 are sleeved on the guiding column 11. The end surface of the rolling diaphragm 42 close to the magnet control valve body 1 is concavely provided with a guiding groove 421 for sleeving on the guiding column 11. In this way, when the rolling diaphragm 42 deforms and the magnet 44 moves, the guiding column 11 can limit the deformation and expansion direction of the rolling diaphragm 42, and at the same time can also limit the moving route of the magnet 44, so as to ensure the accurate alignment among the rolling diaphragm 42, the magnet 44, and the magnet control valve body 1 during the use of the water path valve in this case, and avoid the change of the magnetic force applied by the magnet 44 to the magnet control valve body 1 due to the offset of the magnet 44, which affects the control effect.
[0027] As Figures 2 to 3 shown, preferably, a return spring 45 is provided between the rolling diaphragm 42 and the magnet control valve body 1. The return spring 45 is used to push the end of the rolling diaphragm 42 close to the magnet control valve body 1 away from the magnet control valve body 1.
[0028] In addition, the return spring 45 can also be provided between the magnet 44 and the magnet control valve body 1. At this time, the return spring 45 is used to directly push the magnet 44 away from the magnet control valve body 1.
[0029] As described above, by providing a return spring 45 between the rolling diaphragm 42 and the magnetically controlled valve body 1, or between the magnet 44 and the magnetically controlled valve body 1, it can be effectively ensured that when the rolling diaphragm 42 is not under a large water pressure, the magnet 44 can move away from the magnetically controlled valve body 1 under the elastic force of the return spring 45, thereby ensuring the smooth opening of the magnetically controlled valve body 1. Additionally, due to the provision of the return spring 45, when the rolling diaphragm 42 unfolds, it needs to overcome the elastic force of the return spring 45 synchronously. Thus, by adjusting the elastic coefficient of the magnetically controlled valve body 1, it is possible to accurately control at what water pressure input at the water inlet 5 the magnet 44 applies a strong magnetic force to the magnetically controlled valve body 1, thereby more accurately controlling the operation of the magnetically controlled valve body 1.
[0030] Specifically, the first return spring 43 is also sleeved on the guide post 12.
[0031] As Figures 2 to 3 shown, preferably, the side wall surface of the rolling diaphragm 42 is provided with an annular wave-like fold 422 facilitating the telescopic deformation of the rolling diaphragm 42. In this way, when the water pressure borne by the rolling diaphragm 42 changes, the rolling diaphragm 42 can better achieve deformation through the unfolding and folding of the annular wave-like fold 422, thereby driving the displacement of the magnet 44.
[0032] As Figures 2 to 3 shown, preferably, the magnetically controlled assembly 4 further includes a hollow housing 46. One end of the hollow housing 46 is fixedly connected to the magnetically controlled valve body 1. An annular fixing portion 423 extending outward is provided at the opening edge of the rolling diaphragm 42. The other end of the hollow housing 46 presses the annular fixing portion 423 against the sealing cover 41 to facilitate the sealing of the rolling diaphragm 42. In this way, the rolling diaphragm 42 can be wrapped and protected therein by the hollow housing 46, preventing foreign objects from cutting the side wall of the rolling diaphragm 42 and causing the water path valve to fail. At the same time, through the hollow housing 46, the annular fixing portion 423 can also be pressed against the sealing cover 41 to achieve sealing between the rolling diaphragm 42 and the sealing cover 41, thereby forming a sealed cavity 43.
[0033] As Figures 2 to 3 shown, preferably, a protective cover 47 is further covered on the outer surface of the end of the rolling diaphragm 42 close to the magnetically controlled valve body 1. A receiving groove 471 for placing the magnet 44 is provided on the protective cover 47. In this way, the end face of the rolling diaphragm 42 can be protected by the protective cover 47, preventing foreign objects from cutting the rolling diaphragm 42 and causing the water path valve in this case to fail. At the same time, the magnet 44 can also be more conveniently fixed on the outer surface of the rolling diaphragm 42 through the receiving groove 471 on the protective cover 47.
[0034] As Figures 2 to 3As shown, preferably, a number of limiting buckles 472 for limiting the magnet 44 in the receiving groove 471 are provided at the mouth of the receiving groove 471. In this way, by limiting the magnet 44 in the receiving groove 471 with the limiting buckles 472, it is possible to effectively prevent the magnet 44 from disengaging from the receiving groove 471 during movement, which may cause the waterway valve in this case to fail.
[0035] As described above, the present case protects a waterway valve, and all technical solutions identical or similar to those in the present case should be regarded as falling within the protection scope of the present case.
