Description

Technical Field

[0001] This invention relates to the field of water valve technology, and specifically to a self-regulating water-saving valve. Background Technology

[0002] Water-saving valves, as the name suggests, play a role in saving water. Currently, water-saving valves on the market are mainly used in conjunction with plumbing equipment and sanitary ware such as faucets and urinal flush valves. The water-saving rate is about 50% under a water pressure of 0.3MPa. These water-saving valves mostly achieve their water-saving function by controlling the flow rate.

[0003] In daily life, the following phenomena exist regarding the use of faucets: As we all know, the pump pressure of tap water from water plants is basically constant. However, there is a problem due to the time difference in water usage. During peak and off-peak hours, the water flow from a faucet opened to the same position differs. When using the same container to collect water, during peak hours, the pump pressure in the pipes is lower, resulting in a smaller water flow per unit time and eliminating the possibility of splashing. During off-peak hours, because fewer people are using the water, the pump pressure in the pipes is higher, resulting in a larger water flow per unit time. In these situations, opening the faucet to the same position during these times will cause water to overflow and be wasted. People who frequently cook tend to open the faucet more often, so they may habitually open it to the same spot. Therefore, during off-peak hours, this will inevitably cause water to splash and be wasted, preventing water from completely falling into the container.

[0004] Those skilled in the art of water valve research and design have developed a design concept to address the water wastage caused by water splashing when a faucet is opened at the same position as during peak water usage periods. The reason why the water output of a faucet varies at different times is due to inconsistent pump pressure. Therefore, a self-regulating water-saving valve is proposed to solve the above problem by dynamically controlling the incoming water pressure or flow rate within a small fluctuation range based on the pump pressure. Summary of the Invention

[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0006] A self-regulating water-saving valve includes:

[0007] The valve pipe has an inlet end and an outlet end;

[0008] The flow regulating sleeve is coaxially fixed inside the valve pipe, and its inner diameter gradually decreases from the inlet end to the outlet end.

[0009] An actuator rod is disposed inside the valve pipe and passes through the flow regulating sleeve. A cross baffle and a flow regulating block are installed sequentially on the actuator rod along the direction from the water inlet to the water outlet. There are two cross baffles, which are staggered.

[0010] The dynamic adjustment component includes a balancing component and a resistance component, both of which act on the actuator. The balancing component is used to maintain the balance of the actuator, and the resistance component is used to provide motion resistance to the actuator.

[0011] Furthermore, the balancing assembly includes a handle constructed on the periphery of the valve tube, a balancing tube extending into the valve tube at one end of the handle, a first piston block and a second piston block tightly disposed inside the balancing tube, one end of the actuator rod being connected to the first piston block, and a tension spring connecting the second piston block and the handle.

[0012] Furthermore, a headless screw is threaded onto the handle, one end of the tension spring is connected to the second piston block, and the other end is connected to a mounting block, which is rotatably connected to the headless screw.

[0013] Furthermore, the resistance assembly includes a boss constructed on the periphery of the valve tube and a resistance tube constructed inside the valve tube, the boss and the resistance tube being connected, a third piston being tightly disposed inside the resistance tube, a long rod screw being threadedly connected to the boss, a fourth piston being installed at the end of the long rod screw, a resistance spring being connected between the third piston and the resistance tube, and the other end of the actuator rod being connected to the third piston.

[0014] Furthermore, a plug is installed on the actuator rod, a mounting cover is constructed on the valve pipe, an adjusting rod is threadedly connected to the mounting cover, a drive block is rotatably connected to the end of the adjusting rod, and both the plug and the drive block are constructed with inclined surfaces.

[0015] Furthermore, the actuator includes a first linkage rod and a second linkage rod. One end of the first linkage rod is connected to the block, and both ends of the second linkage rod are connected to the third piston and the block, respectively. A transmission rod is rotatably mounted inside the block, and a power rod is rotatably mounted inside the first linkage rod. A support rod is mounted on the first piston block, and the power rod is rotatably connected to the support rod. A turbine is mounted on the power rod, and an impeller is rotatably mounted on the second linkage rod. The power rod and the transmission rod are connected by a first gear set, and the transmission rod and the impeller are connected by a second gear set.

[0016] Furthermore, the transmission ratio of the first gear set is less than [value missing], and the transmission ratio of the second gear set is less than [value missing].

[0017] Furthermore, the transmission ratio of the first gear set is greater than 1, and the transmission ratio of the second gear set is greater than 1.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. This invention reduces the water pressure entering the user's faucet by keeping the flow regulating sleeve at a very low opening degree during off-peak water usage periods, in conjunction with the extremely high flow rate at this time. At the same time, during peak water usage periods, the flow regulating sleeve is opened to a very high degree, in conjunction with the extremely low flow rate at this time. Furthermore, during other time periods, the cross baffle, the balancing component, and the resistance component can all be dynamically adjusted accordingly to avoid water waste caused by splashing, thereby achieving the goal of water conservation.

[0020] 2. In order to adapt to the water pressure conditions in different regions, both the balancing component and the resistance component of this invention can be adjusted. The force of the balancing component and the resistance component against the cross baffle plate can be adjusted in real time according to the actual situation. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] The following is combined Figures 1 to 6 The present invention will be described in detail below.

[0030] Example 1

[0031] In Embodiment 1, this application proposes a self-adjusting water-saving valve, comprising:

[0032] Valve pipe 1 has an inlet end and an outlet end. In this application, valve pipe 1 is equipped with flanges at both ends. Threaded joints can be installed at both ends of valve pipe 1 by means of flange connection. Currently, valves used in water supply pipelines are installed by means of threaded connection. In this application, threaded joints can be installed at the inlet end and the outlet end by means of flange connection. Then, valve pipe 1 is installed between the water supply pipeline and the faucet.

[0033] The flow regulating sleeve 2 is coaxially fixed inside the valve pipe 1, and its inner diameter gradually decreases from the inlet end to the outlet end. Figure 3 Taking the perspective as an example, the internal structure of the flow regulating sleeve 2 is a tapered hole structure;

[0034] The actuator 3 is located inside the valve pipe 1 and passes through the flow regulating sleeve 2. A cross baffle 5 and a flow regulating block 4 are installed sequentially on the actuator 3 from the water inlet to the water outlet. The shape of the flow regulating block 4 is adapted to the cone hole structure. There are two cross baffles 5, which are staggered. The two cross baffles 5 are staggered to form a double obstruction, but do not affect the flow of water. The purpose is to make greater use of the water flow to drive the actuator 3 to move, so as to realize the dynamic position adjustment of the flow regulating block 4 and the flow regulating sleeve 2 on the actuator 3. The cross baffle 5 is slidably connected to the inner wall of the valve pipe 1.

[0035] The dynamic adjustment component 6 includes a balancing component 7 and a resistance component 8, both of which act on the actuator 3. The balancing component 7 is used to maintain the balance of the actuator 3, and the resistance component 8 is used to provide motion resistance to the actuator 3.

[0036] Based on the above disclosure: With the two intersecting cross-shaped baffles 5 of this invention, during the process of water from the water plant being pumped to the inlet pipe and entering the user's internal water circuit via the valve pipe 1, the following situations may occur:

[0037] 1. During the off-peak water usage period, the water flow inside valve pipe 1 is large. The water flow impacts the two cross baffles 5, causing the flow regulating block 4 to move towards the flow regulating sleeve 2. Since the flow regulating sleeve 2 has a conical hole structure for the water flow, and the flow regulating block 4 is truncated cone-shaped, the larger the water flow, the deeper the flow regulating block 4 is inserted into the flow regulating sleeve 2. Thus, the cross-sectional area of ​​the flow is smaller and the flow rate is faster, but the flow rate per unit time is at a relatively moderate value. This is to control the water pressure entering the faucet to a reasonable state to avoid splashing when the faucet is turned on.

[0038] Second, when it is the peak water usage period, the force of the water flow at the inlet acting on the cross baffle 5 gradually decreases. Under the action of the dynamic adjustment component 6, it begins to drive the flow regulating block 4 away from the flow regulating sleeve 2, so that the flow cross-sectional area increases and the flow velocity is slow, but the flow rate per unit time is in a relatively reasonable state, that is, the flow rate per unit time is controlled by two factors: flow velocity and flow cross-sectional area.

[0039] This design reduces water pressure at the user's tap by keeping the flow regulating sleeve 2 at a minimal opening during off-peak water usage periods, coinciding with the high flow rate at that time. Conversely, during peak water usage periods, the flow regulating sleeve 2 is opened to a maximum opening to match the extremely low flow rate. Furthermore, at other times, the cross-shaped baffle 5 and the dynamic adjustment component 6 can be dynamically adjusted accordingly to prevent water waste caused by splashing, thus achieving water conservation. Figure 3 and Figure 4 As shown, slots are constructed on the inner wall of the flow regulating sleeve 2. The slots are arranged in an array along the inner wall of the flow regulating sleeve 2. The purpose of this design is that when the water pressure is extremely high and the flow regulating block 4 is fully inserted into the flow regulating sleeve 2, the basic flow can still be guaranteed through the slots. At this time, the water source can flow through the slots.

[0040] Example 2

[0041] This embodiment is a further improvement on the application based on Embodiment 1, specifically, the structure of the dynamic adjustment component 6 is disclosed in detail.

[0042] like Figure 2 , Figure 3 and Figure 6 As shown, the balancing assembly 7 includes a handle 701 constructed on the periphery of the valve tube 1. A balancing tube 702 extending into the valve tube 1 is connected to the handle 701. A first piston block 703 and a second piston block 704 are tightly arranged inside the balancing tube 702. One end of the actuator 3 is connected to the first piston block 703. A tension spring 705 is connected between the second piston block 704 and the handle 701.

[0043] A headless screw 706 is threaded onto the handle 701. One end of the tension spring 705 is connected to the second piston block 704, and the other end is connected to the mounting block 707. The mounting block 707 is rotatably connected to the headless screw 706.

[0044] The resistance assembly 8 includes a boss 804 constructed on the periphery of the valve tube 1 and a resistance tube 801 constructed inside the valve tube 1. The boss 804 and the resistance tube 801 are connected. A third piston 802 is tightly disposed inside the resistance tube 801. A long rod screw 805 is threadedly connected to the boss 804. A fourth piston 806 is installed at the end of the long rod screw 805. A resistance spring 803 is connected between the third piston 802 and the resistance tube 801. The other end of the actuator 3 is connected to the third piston 802.

[0045] As the water flow pushes the cross-shaped baffle 5 and drives the actuator 3, the actuator 3 pushes the third piston 802 to move inside the resistance tube 801. At this time, the space between the third piston 802 and the fourth piston 806 narrows, and the air is compressed, forming resistance. The resistance spring 803 is then compressed, generating a reaction force that forces the actuator 3 to return to its original position. This structural design forms a resistance buffer, while the third piston 802 and the fourth piston 806 form a damping structure. The purpose is to prevent the actuator 3 from moving rapidly due to excessive water pressure, causing the flow regulating block 4 to rapidly impact the flow regulating sleeve 2, resulting in vibration and wear. Furthermore, it needs to be used in conjunction with the balancing assembly 7. The dynamic adjustment is as follows: when the actuator 3 moves from the inlet end to the outlet end, the first piston block 703 moves together with the actuator 3. At this time, the space between the first piston block 703 and the second piston block 704 increases, while the pressure decreases. Then, with the cooperation of the tension spring 705, the second piston block 704 is pushed to move towards the first piston block 703 to maintain the positional stability of the actuator 3 and avoid insufficient overall balance caused by unilateral force. Secondly, in this application, with the cooperation of the headless screw 706 and the long rod screw 805, the resistance component 8 and the balance component 7 can be adjusted. The force of the balance component 7 and the resistance component 8 can be adjusted by changing the positions of the second piston and the fourth piston 806 respectively.

[0046] In summary, in order to adapt to the water pressure conditions in different regions and to avoid the cross baffle 5 being subjected to excessive impact force and failing to play a good dynamic adjustment role, a dynamic adjustment component 6 is designed. This component can be used to adjust the force acting on the cross baffle 5 in real time according to the actual situation.

[0047] Example 3

[0048] This embodiment is a further improvement upon Embodiments 1 and 2. Considering that the valve has a completely sealing function, this application discloses the following:

[0049] A plug 9 is installed on the actuator 3, and a mounting cover 10 is constructed on the valve pipe 1. An adjusting rod 18 is threadedly connected to the mounting cover 10, and a drive block 17 is rotatably connected to the end of the adjusting rod 18. Both the plug 9 and the drive block 17 are constructed with inclined surfaces.

[0050] Based on the above, when the valve is completely closed, it is only necessary to rotate the adjusting rod 18 to move the driving block 17. After the driving block 17 contacts the block 9, the mutual inclined surfaces will push the block 9 to move and block one end of the flow regulating sleeve 2. At this time, the slot will also be blocked. Since the actuator 3 also moves, the resistance spring 803 and the tension spring 705 will deform. When the adjusting rod 18 is rotated again to move the driving block 17 away from the block 9, it can be reset under the cooperation of water flow, resistance spring 803 and tension spring 705, so as to realize the normal flow of water. The side of the block 9 close to the flow regulating sleeve 2 is equipped with a sealing gasket.

[0051] Example 4

[0052] This embodiment further improves upon Embodiments 1, 2, and 3 of this application. This application also discloses that: the actuator 3 includes a first linkage 301 and a second linkage 302. One end of the first linkage 301 is connected to the block 9, and both ends of the second linkage 302 are respectively connected to the third piston 802 and the block 9. A transmission rod 11 is rotatably mounted inside the block 9. A power rod 16 is rotatably mounted inside the first linkage 301. A support rod 708 is mounted on the first piston block 703, and the power rod 16 is rotatably connected to the support rod 708. A turbine 14 is mounted on the lever 16, and an impeller 15 is rotatably mounted on the second linkage 302. The power lever 16 and the transmission lever 11 are connected by a first gear set 12, and the transmission lever 11 and the impeller 15 are connected by a second gear set 13. When water flows through the turbine 14, it drives the turbine 14 to rotate, thereby driving the power lever 16 to rotate. Then, under the transmission of the first gear set 12, the transmission lever 11 rotates. Finally, under the transmission of the second gear set 13, the impeller 15 rotates. The purpose of this structural design is based on the following two situations:

[0053] 1. In order to further reduce water flow during off-peak water usage periods in areas with excessive water pressure, the transmission ratio of the first gear set 12 is less than 1, and the transmission ratio of the second gear set 13 is less than 1. Both the first gear set 12 and the second gear set 13 consist of two meshing gears. The working principle is as follows: the rotation of the turbine 14 consumes water pressure, and the rotation of the impeller 15 also consumes water pressure, making the transmission between the turbine 14 and the impeller 15 a force-intensive mechanism to further reduce water pressure. Therefore, the turbine 14 needs to provide a very high speed so that the impeller 15 can operate at a relatively normal speed, thus further reducing the water pressure.

[0054] II. In order to ensure a sufficiently large water output during peak water usage periods in areas with low water pressure, the transmission ratio of the first gear set 12 is greater than 1, and the transmission ratio of the second gear set 13 is greater than 1. The rotation of the turbine 14 consumes water pressure, and the rotation of the impeller 15 also consumes water pressure. This makes the transmission between the turbine 14 and the impeller 15 a force-saving mechanism to increase water pressure. The turbine 14 only needs to provide a lower speed to make the impeller 15 operate at a higher speed, thus increasing the water pressure.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
