Description

Technical Field

[0001] This utility model relates to a water valve, and more particularly to a compact water valve that is not electrically driven. Background Technology

[0002] Currently, water valves, as accessories for controlling the opening and closing of pipelines, are widely used in the water systems of various water dispensers and water purifiers. Common water valves mainly have two control methods: one is manual operation, and the other is electric drive combined with electrical signal control, such as solenoid valves. Manual water valves have low deployment and maintenance costs, but the need for manual operation makes them unsuitable for complex water systems; while electrically controlled water valves can achieve more complex control effects, their cost is much higher than ordinary valves due to their sophisticated circuit design, and they also require a corresponding circuit control system for use.

[0003] To address the shortcomings of the two common types of valves mentioned above, researchers have developed a valve that can be controlled by water pressure. However, this type of valve currently requires at least three parts: an inlet valve, an outlet valve, and a magnetic control unit. The inlet and outlet valves are connected by a water circuit, while the magnetic control unit also needs to be connected to the control water circuit. Therefore, this type of valve controlled by water pressure often requires a lot of space.

[0004] Therefore, overcoming the defects of valves controlled by water pressure has become an important issue that needs to be addressed by those skilled in the art. Utility Model Content

[0005] This invention overcomes the shortcomings of the above-mentioned technologies and provides a compact, non-electrically driven water valve.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A compact, electrically driven water valve includes a magnetically controlled valve body 1 and a water-controlled magnetic box 2. The magnetically controlled valve body 1 is fixed to the surface of the water-controlled magnetic box 2. The magnetically controlled valve body 1 has a first inlet 11 and a first outlet 12. The magnetically controlled valve body 1 controls the opening / closing of the water passage between the first inlet 11 and the first outlet 12 according to the strength of the magnetic force it receives. The water-controlled magnetic box 2 has a water pressure response chamber 21. The water-controlled magnetic box 2 is used to control whether to apply a strong magnetic force to the magnetically controlled valve body 1 according to the small / large water pressure in the water pressure response chamber 21. The water-controlled magnetic box 2 also has a second inlet 22 and a second outlet 23, both of which are connected to the water pressure response chamber 21. The second inlet 22 is connected to the first outlet 12. The second outlet 23 is used to connect to external water-using equipment and is normally closed. The second outlet 23 is opened after being connected to the external water-using equipment.

[0008] Preferably, the water-controlled magnetic box 2 includes a hollow box body 24, and an annular rolling diaphragm 25 is disposed inside the hollow box body 24. The outer edge of the annular rolling diaphragm 25 is fixed to the inner wall of the hollow box body 24. A movable plate 26 is sealed and fixed at the inner edge of the annular rolling diaphragm 25. The annular rolling diaphragm 25 and the movable plate 26 are used to divide the interior of the hollow box body 24 into two mutually isolated spaces. One of these two mutually isolated spaces is the water pressure response chamber 21, and the other is the reset chamber 27. A first reset spring 28 is provided in the reset chamber 27 and is supported between the movable plate 26 and the inner wall of the hollow box body 24. The first reset spring 28 is used to apply elastic force to the movable plate 26 to provide a tendency for the movable plate 26 to move in the direction of compressing the water pressure response chamber 21. A magnet 29 is also fixed on the movable plate 26. The magnet 29 is used to approach the magnetic control valve body 1 when the movable plate 26 moves in the direction of compressing the water pressure response chamber 21 so as to apply a strong magnetic force to the magnetic control valve body 1.

[0009] Preferably, the hollow box 24 includes a connecting box 241 and a box cover 242. The connecting box 241 has a mounting surface for the magnetic valve body 1 to be attached and fixed thereon and an opening facing away from the mounting surface. The box cover 242 is sealed to the opening. A first slot 243 is formed between the opening and the box cover 242 for the outer edge of the annular rolling diaphragm 25 to be inserted and fixed therein. The annular rolling diaphragm 25 and the movable plate 26 are located between the connecting box 241 and the box cover 242. The water pressure response chamber 21 is located on one side of the connecting box 241 and the reset chamber 27 is located on one side of the box cover 242. The first reset spring 28 abuts between the box cover 242 and the movable plate 26. The box cover 242 is also provided with an exhaust hole 244 communicating with the reset chamber 27. The second water inlet 22 and the second water outlet 23 are both provided on the connecting box 241.

[0010] Preferably, the magnetic valve body 1 is provided with a protruding iron core 13 for sensing the magnitude of the magnetic force, and the hollow box 24 is also provided with a connection port 245 for inserting the iron core 13 into the water pressure response chamber 21. The connection port 245 is sealed to the magnetic valve body 1, and the movable plate 26 is sleeved on the iron core 13 and moves closer to / away from the magnetic valve body 1.

[0011] Preferably, the movable plate 26 includes a sealing member 261 and a guide member 262 fixed together. A second slot 263 is formed between the sealing member 261 and the guide member 262 for the inner edge of the annular rolling diaphragm 25 to be inserted and fixed therein. The guide member 262 is provided with a guide groove 264 sleeved on the iron core part 13. The sealing member 261 is provided with a plug head 265 for blocking the guide groove 264. The plug head 265 is sealed to the guide groove 264. The magnet 29 is fixed between the sealing member 261 and the guide member 262 and isolated from the water channel. The first return spring 28 abuts between the sealing member 261 and the hollow box 24.

[0012] Preferably, the first reset spring 28 is a variable diameter spring whose diameter gradually increases from one end to the other.

[0013] Preferably, a sealing valve core 231 is inserted into the second outlet 23, which can block the second outlet 23 after being moved outward. A second return spring 232 is also provided at the second outlet 23 to drive the sealing valve core 231 to move outward and reset.

[0014] Preferably, the water-controlled magnetic box 2 is also fixed with a baffle 3 for pressing the magnetic valve body 1 against the surface of the water-controlled magnetic box 2.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This design achieves the same on / off control function as existing water valves based on water pressure using a magnetically controlled valve body and a water-controlled magnetic box. The water-controlled magnetic box integrates the functions of the outlet valve and the magnetic control component, significantly reducing the size of the water valve itself and saving more space in the water system. Furthermore, the water valve in this design does not require an additional control circuit. After being connected to external water-using equipment, the valve's on / off function is directly controlled by the water pressure in the outlet circuit. This effectively reduces the complexity of the water circuit in actual use, further reducing the required water circuit configuration. This also allows for space redundancy in the water system for other purposes or directly reduces the overall size of the water system. Attached Figure Description

[0023] The following embodiments further illustrate the features of this utility model and other related features in detail, so as to facilitate understanding by those skilled in the art:

[0024] like Figures 1 to 6 As shown, a compact, electrically driven water valve includes a magnetically controlled valve body 1 and a water-controlled magnetic box 2. The magnetically controlled valve body 1 is fixed to the surface of the water-controlled magnetic box 2. The magnetically controlled valve body 1 has a first inlet 11 and a first outlet 12. The magnetically controlled valve body 1 controls the flow of water between the first inlet 11 and the first outlet 12 according to the strength of the magnetic force it receives. The water-controlled magnetic box 2 has a water pressure response chamber 21. The water-controlled magnetic box 2 is used to control whether to apply a strong magnetic force to the magnetically controlled valve body 1 according to the water pressure in the water pressure response chamber 21. The water-controlled magnetic box 2 also has a second inlet 22 and a second outlet 23, both of which are connected to the water pressure response chamber 21. The second inlet 22 is connected to the first outlet 12. The second outlet 23 is used to connect to external water-using equipment and is normally closed. The second outlet 23 is opened after being connected to the external water-using equipment.

[0025] The water valve in this case includes a magnetically controlled valve body 1 and a water-controlled magnetic box 2, both of which are provided with inlet and outlet ports. The first outlet 12 and the second inlet 22 are connected, with the first inlet 11 serving as the inlet of the entire water valve and the second outlet 23 serving as the outlet. The water-controlled magnetic box 2 has a water pressure response chamber 21, which is connected to the second inlet 22 and the second outlet 23. The water-controlled magnetic box 2 can control whether to apply a stronger magnetic force to the magnetically controlled valve body 1 based on the water pressure in the water pressure response chamber 21. Specifically, when the water pressure in the water pressure response chamber 21 increases to a certain threshold, the water-controlled magnetic box 2 will stop applying a stronger magnetic force to the magnetically controlled valve body 1, and when the water pressure in the water pressure response chamber 21 decreases to a certain threshold, the water-controlled magnetic box 2 will apply a stronger magnetic force to the magnetically controlled valve body 1 again, thereby realizing the control of the magnetically controlled valve body 1 by water pressure. Moreover, the second outlet 23 is normally closed and will only open after it is connected to the external water-using equipment. In this case, when the water valve is not connected to the water-using equipment, the water pressure response chamber 21 will directly bear the inlet water pressure and thus force the magnetic valve body 1 to close, thereby preventing water leakage.

[0026] As described above, this invention achieves the function of controlling the on / off state of existing water valves based on water pressure using the magnetically controlled valve body 1 and the water-controlled magnetic box 2. The water-controlled magnetic box 2 integrates the functions of the outlet valve and the magnetic control component, significantly reducing the size of the water valve itself and saving more space in the water system. Furthermore, the water valve in this invention does not require additional control water circuits. After being connected to external water-using equipment, the valve's on / off state can be directly controlled based on the water pressure of the outlet water circuit. This effectively reduces the complexity of the water circuit when actually using the valve, further reducing the required water circuits. This also allows for space redundancy in the water system for other purposes or directly reduces the overall volume of the water system.

[0027] Specifically, the magnetically controlled valve body 1 has the same on / off structure as a conventional solenoid valve. The difference is that the magnetically controlled valve body 1 is not connected to electricity and does not have an electromagnetic coil for generating magnetic force.

[0028] like Figure 3 , Figure 4 and Figure 6As shown, preferably, the water-controlled magnetic box 2 includes a hollow box body 24. An annular rolling diaphragm 25 is disposed inside the hollow box body 24. The outer edge of the annular rolling diaphragm 25 is fixed to the inner wall of the hollow box body 24. A movable plate 26 is sealed and fixed at the inner edge of the annular rolling diaphragm 25. The annular rolling diaphragm 25 and the movable plate 26 are used to divide the interior of the hollow box body 24 into two mutually isolated spaces. One of these two mutually isolated spaces is the water pressure response chamber 21, and the other is the reset chamber 27. A first reset spring 28 is provided in the reset chamber 27, which is supported between the movable plate 26 and the inner wall of the hollow box body 24. The first reset spring 28 is used to apply elastic force to the movable plate 26, giving the movable plate 26 a tendency to move towards the compressed water pressure response chamber 21. A magnet 29 is also fixed on the movable plate 26. The magnet 29 is used to approach the magnetic control valve body 1 when the movable plate 26 moves towards the compressed water pressure response chamber 21, so as to apply a strong magnetic force to the magnetic control valve body 1.

[0029] As described above, the water-controlled magnetic box 2 of this case includes a hollow box 24. The hollow box 24 is divided into two mutually isolated spaces by an annular rolling diaphragm 25 and a movable plate 26: a water pressure response chamber 21 and a reset chamber 27. The water pressure response chamber 21 is connected to the second inlet 22 and the second outlet 23. The reset chamber 27 is equipped with a first reset spring 28 supported between the movable plate 26 and the inner wall of the hollow box 24. When the water pressure in the water pressure response chamber 21 does not reach a certain threshold, the movable plate 26 cannot overcome the elastic force of the first reset spring 28. Therefore, the movable plate 26 is pushed by the first reset spring 28 towards the magnetic control valve body 1, simultaneously deforming the annular rolling diaphragm 25. This causes the magnet 29 fixed on the movable plate 26 to also approach the magnetic control valve body 1, applying a strong magnetic force to it. When the water pressure in the water pressure response chamber 21 reaches a certain threshold, the movable plate 26 can overcome the elastic force of the first return spring 28 and move away from the magnetic valve body 1. Consequently, the magnet 29 will also move away from the magnetic valve body 1, thus weakening the magnetic force on the magnetic valve body 1. Therefore, under the action of the annular rolling diaphragm 25, the movable plate 26, the first return spring 28, and the magnet 29, the water-controlled magnetic box 2 can control the magnetic valve body 1 according to the water pressure in the water pressure response chamber 21.

[0030] like Figure 3 , Figure 4 and Figure 6As shown, preferably, the hollow box 24 includes a connecting box 241 and a box cover 242. The connecting box 241 has a mounting surface for the magnetic valve body 1 to be attached and fixed thereon and an opening facing away from the mounting surface. The box cover 242 is sealed to the opening. A first slot 243 is also formed between the opening and the box cover 242 for the outer edge of the annular rolling diaphragm 25 to be inserted and fixed therein. The annular rolling diaphragm 25 and the movable plate 26 are located between the connecting box 241 and the box cover 242. The water pressure response chamber 21 is located on one side of the connecting box 241 and the reset chamber 27 is located on one side of the box cover 242. The first reset spring 28 abuts between the box cover 242 and the movable plate 26. The box cover 242 is also provided with an exhaust hole 244 communicating with the reset chamber 27. The second water inlet 22 and the second water outlet 23 are both provided on the connecting box 241.

[0031] As described above, the hollow box 24 in this case includes a connecting box 241 and a lid 242. The second water inlet 22 and the second water outlet 23 are both located on the connecting box 241. A first groove 243 is formed between the opening of the connecting box 241 and the lid 242. This first groove 243 effectively fixes the annular rolling diaphragm 25 to the inner wall of the hollow box 24, creating an effective seal to prevent water leakage at the connection between the connecting box 241 and the lid 242. It also provides a partial sealing basis for isolating the water pressure response chamber 21 and the reset chamber 27. Furthermore, the lid 242 is provided with a vent 244 communicating with the reset chamber 27. Thus, when the movement of the movable plate 26 and the annular rolling diaphragm 25 causes a change in the size of the reset chamber 27, the vent 244 ensures that the air pressure in the reset chamber 27 remains consistent with the external pressure, preventing air from accumulating in the reset chamber 27 and hindering the movement of the movable plate 26.

[0032] like Figure 3 , Figure 4 and Figure 6 As shown, preferably, the magnetic valve body 1 is provided with a protruding iron core 13 for sensing the magnitude of the magnetic force, and the hollow box 24 is also provided with a connection port 245 for inserting the iron core 13 into the water pressure response chamber 21. The connection port 245 is sealed to the magnetic valve body 1, and the movable plate 26 is sleeved on the iron core 13 and moves closer to / away from the magnetic valve body 1.

[0033] As described above, inserting the iron core 13 into the water pressure response chamber 21 via the connection port 245 allows the magnetic valve body 1 to respond more precisely to changes in magnetic force, avoiding the impact of the thickness of the hollow box 24 on the operating accuracy of the magnetic valve body 1. Simultaneously, fitting the movable plate 26 onto the iron core 13 ensures that the movable plate 26 does not deviate in direction during movement, ensuring that the magnetic force of the magnet 29 can be accurately and efficiently applied to the iron core 13.

[0034] like Figure 3, Figure 4 and Figure 6 As shown, preferably, the movable plate 26 includes a sealing member 261 and a guide member 262 fixed together front and rear. A second slot 263 is formed between the sealing member 261 and the guide member 262 for the inner edge of the annular rolling diaphragm 25 to be inserted and fixed therein. The guide member 262 is provided with a guide groove 264 sleeved on the iron core part 13. The sealing member 261 is provided with a plug head 265 for blocking the guide groove 264. The plug head 265 is sealed to the guide groove 264. The magnet 29 is fixed between the sealing member 261 and the guide member 262 and isolated from the water channel. The first return spring 28 abuts between the sealing member 261 and the hollow box body 24.

[0035] As described above, the movable plate 26 in this case includes a sealing member 261 and a guide member 262 fixed together front and rear, with a second groove 263 formed between them. By fixing the inner edge of the annular rolling diaphragm 25 through the second groove 263, the movable plate 26 can be firmly fixed to the inner edge of the annular rolling diaphragm 25, forming an effective seal and providing a partial sealing basis for the mutual isolation between the water pressure response chamber 21 and the reset chamber 27. The guide member 262 is provided with a guide groove 264 for fitting onto the iron core part 13, which can effectively limit the movement direction of the movable plate 26. At the same time, by using the plug head 265 on the sealing member 261 to seal the guide groove 264, water in the water pressure response chamber 21 can be effectively prevented from flowing into the reset chamber 27 through the guide groove 264. In addition, fixing the magnet 29 between the sealing member 261 and the guide member 262 can effectively isolate the magnet 29 from the water channel, preventing the magnet 29 from contaminating the water channel.

[0036] Specifically, the magnet 29 is sleeved on the outer wall of the guide groove 264.

[0037] like Figure 3 , Figure 4 and Figure 6 As shown, preferably, the first return spring 28 is a variable diameter spring whose diameter gradually increases from one end to the other. In this way, when the first return spring 28 is compressed, the first return spring 28 can occupy a smaller height in the axial direction, thereby reducing the space that needs to be reserved for the return cavity 27, and further reducing the volume of the water valve in this case.

[0038] like Figure 3 , Figure 4 and Figure 6As shown, preferably, a sealing valve core 231 is inserted into the second water outlet 23, which can block the second water outlet 23 after being moved outward. A second return spring 232 is also provided at the second water outlet 23 to drive the sealing valve core 231 to move outward and reset. In this way, when the second water outlet 23 is not connected to the external water equipment, the sealing valve core 231 will move outward under the drive of the second return spring 232 to block the second return spring 232. When connected to the external water equipment, the external water equipment can be used to push the sealing valve core 231 inward, so that the sealing valve core 231 can overcome the elastic force of the second return spring 232 and move inward, thereby opening the second water outlet 23.

[0039] like Figure 5 and Figure 6 As shown, preferably, the water-controlled magnetic box 2 is also fixed with a baffle 3 for pressing the magnetic valve body 1 against the surface of the water-controlled magnetic box 2. In this way, the baffle 3 can prevent the magnetic valve body 1 from separating from the water-controlled magnetic box 2, and prevent the magnetic valve body 1 from detaching from the water-controlled magnetic box 2 under the action of strong magnetic force, thus preventing the water valve in this case from failing.

[0040] As stated above, this case protects a compact, non-electrically driven water valve, and all technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
