Description

Technical Field

[0001] The present invention relates to the technical field of water flow detection and regulation, and in particular to a flow regulating valve and a flow regulating system. Background Art

[0002] A flow control valve is a multifunctional valve that uses a high-precision pilot control method to control flow. It is suitable for water distribution pipes where both flow and pressure control are required. It maintains the intended flow rate, limits excess flow to a predetermined value, and appropriately reduces the upstream high pressure. Even if the pressure upstream of the main valve changes, the flow rate downstream of the main valve is not affected.

[0003] Existing flow control valves have a regulating plate installed above the water outlet. The opening or closing of the water outlet is controlled by adjusting the position of the regulating plate. However, when the regulating plate closes the water outlet, the instantaneous impact force generated by the flowing water will directly act on the regulating plate. After long-term use, the regulating plate is prone to damage, which affects the effect of regulating the water flow. Summary of the Invention

[0004] The purpose of the present invention is to provide a flow regulating valve and a flow regulating system, aiming to solve the problem in the prior art that the regulating plate of the flow regulating valve is easily deformed due to the large water impact force when closing the water outlet.

[0005] In order to achieve the above-mentioned objectives, the present invention provides a flow regulating valve in the first aspect, including a valve body, wherein a water inlet chamber, a regulating chamber and a first water outlet chamber are sequentially provided inside the valve body along the direction of water flow; a first water outlet is provided in the first water outlet chamber; a rotating body, which is rotatably installed in the regulating chamber; an adjusting ring, which is arranged in the regulating chamber and connected to the rotating body; a stepped groove is provided on the outer wall of the adjusting ring; when the adjusting ring is driven by the rotating body to rotate to partially block the first water outlet, the water can flow out of the first water outlet through the stepped groove.

[0006] In the present application, a rotatable rotating body and an adjusting ring are provided inside the valve body. By rotating and adjusting the position of the adjusting ring, the first water outlet can be closed or opened, thereby adjusting the water volume. At the same time, a stepped groove is provided on the outer wall of the adjusting ring. During the process from partially blocking the first water outlet by the adjusting ring until the adjusting ring continuously rotates to blocking the first water outlet, the water flow can flow out of the first water outlet in a step-by-step decreasing manner through the stepped groove, thereby providing a buffer channel for the instantaneous stop of the water flow, reducing the impact force of the water flow on the adjusting ring, and improving the working life of the adjusting ring. At the same time, the adjusting ring can rotate clockwise or counterclockwise with the rotating body, so that the user can flexibly adjust the flow rate.

[0007] Furthermore, the rotating body is installed in the regulating cavity perpendicular to the direction of water flow. Compared with the sheet structure perpendicular to the direction of water flow, which is prone to component damage due to excessive water flow, the side wall of the regulating ring is perpendicular to the direction of water flow, and its ability to withstand water flow impact is stronger and the structure is more stable.

[0008] Furthermore, the adjustment ring is sleeved on the outside of the rotating body, and a water flow path is formed between the adjustment ring and the rotating body; the adjustment ring includes a first section and a second section, the first section is arranged above the first water outlet, and the second section is arranged in the direction of the water inlet cavity; the first section includes a first body and a first notch; when the first body rotates to above the first water outlet, the first water outlet is partially closed; when the first notch rotates to above the first water outlet, the first water outlet is open.

[0009] Furthermore, the stepped groove is provided on the outer wall of the first body. The stepped groove includes a first end and a second end, the first end communicating with the first notch; the groove width of the first end is greater than the groove width of the second end. When the adjustment ring rotates until the first body is above the first water outlet, water flows through the water flow path between the adjustment ring and the rotating body to the first notch, and then enters the stepped groove, thereby gradually reducing the water flow rate and mitigating the instantaneous impact force of the water flow on the adjustment ring.

[0010] Furthermore, the second section includes a second body and a second notch; a mounting hole is provided on the second body, a connecting rod is passed through the rotating body, and both ends of the connecting rod are arranged in the mounting hole so that the adjustment ring rotates with the rotating body.

[0011] Furthermore, when the second notch rotates to the position corresponding to the water inlet chamber, the water flow can smoothly flow from the water inlet chamber into the regulating chamber and into the water flow path between the regulating ring and the rotating body. The first notch or the stepped groove is above the first water outlet, and the water flow rate is larger at this time.

[0012] Furthermore, a second water outlet chamber is provided in the valve body, the second water outlet chamber is communicated with the regulating chamber, and a second water outlet is provided in the second water outlet chamber; a shaft sleeve is also provided in the valve body, the shaft sleeve is sleeved outside the rotating body and installed in the valve body, and the shaft sleeve abuts against the second water outlet to close the second water outlet.

[0013] Furthermore, a spring is provided between the rotating body and the sleeve, one end of the spring abuts against the rotating body, and the other end abuts against the sleeve. When the spring is in a compressed state, the sleeve abuts against the second water outlet to close the second water outlet.

[0014] Furthermore, the flow regulating valve also includes a servo motor, which is electrically connected to the rotating body; the rotating body includes a front end and a rear end, the front end is connected to the sleeve, and the rear end is connected to the servo motor; the servo motor drives the rotating body to rotate and move backward, so that the spring is released and the sleeve is disengaged from the second water outlet, and the second water outlet is opened.

[0015] In a second aspect, the present application provides a flow regulating system, which includes a shell, in which a water pipe and a flow regulating valve as described in any one of the above items are provided; the flow regulating valve is connected to the water pipe.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0027] In addition, in this application, unless otherwise specified, "plurality" refers to two or more. "And / or" describes the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, or B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0028] like Figure 1 As shown, the present invention provides a flow regulating valve in the first aspect, which includes a valve body 1, wherein a water inlet chamber 11, a regulating chamber 12 and a first water outlet chamber 13 are sequentially provided inside the valve body along the direction of water flow; a first water outlet 13 is provided in the first water outlet chamber 13; a rotating body 2, which is rotatably installed in the regulating chamber 12; an adjusting ring 3, which is arranged in the regulating chamber 12 and connected to the rotating body 2; when the rotating body 2 rotates, the adjusting ring 3 can rotate with the rotating body 2; a stepped groove 311 is provided on the outer wall of the adjusting ring 3; when the adjusting ring 3 rotates to partially block the first water outlet 131, water can flow out of the first water outlet 131 through the stepped groove 311.

[0029] In the present application, a rotatable rotating body 2 and an adjusting ring 3 are provided inside the valve body 1. By rotating and adjusting the position of the adjusting ring 3, the first water outlet 131 can be closed or opened, thereby adjusting the water volume. At the same time, a stepped groove 311 is provided on the outer wall of the adjusting ring 3. During the process from partially blocking the first water outlet 131 by the adjusting ring 3 until the adjusting ring 3 continuously rotates to blocking the first water outlet 131, the water flow can flow out of the first water outlet 131 in a step-by-step decreasing manner through the stepped groove 311, thereby providing a buffer channel for the instantaneous stop of the water flow, gradually reducing the impact force of the water flow on the adjusting ring 3, and improving the service life of the adjusting ring 3; at the same time, the adjusting ring 3 can rotate clockwise or counterclockwise with the rotating body 2, so that the user can flexibly adjust the flow rate.

[0030] Furthermore, the rotating body 2 is installed in the regulating chamber 12 perpendicular to the direction of water flow. Compared with the sheet structure perpendicular to the direction of water flow, which is prone to component damage due to excessive water flow, the side wall of the regulating ring 3 is perpendicular to the direction of water flow, and its ability to withstand water flow impact is stronger and the structure is more stable. At the same time, a general valve body has a shorter cavity between the water inlet chamber and the first water outlet chamber. At this time, a structure perpendicular to the direction of water flow is adopted, which will not take up too much installation space to achieve the effect of regulating the water flow, thereby saving production costs.

[0031] like Figure 2 As shown, further, the adjusting ring 3 is sleeved on the outside of the rotating body 2, and a water flow path is formed between the adjusting ring 3 and the rotating body 2; the adjusting ring 3 includes a first section and a second section, the first section is arranged above the first water outlet 131, and the second section is arranged in the direction of the water inlet chamber 11; the first section includes a first body 31 and a first notch 32; when the first body 31 rotates to above the first water outlet 131, the first water outlet 131 is closed; when the first notch 32 rotates to above the first water outlet 131, the first water outlet 131 is opened.

[0032] like Figure 3 As shown, the outer wall of the first body 31 is further provided with the stepped groove 311. The stepped groove 311 includes a first end and a second end, with the first end communicating with the first notch 32. The groove width of the first end is greater than the groove width of the second end. When the adjustment ring 3 rotates until the first body 31 is above the first water outlet 131, water flows through the water flow path between the adjustment ring 3 and the rotating body 2 to the first notch 32, then enters the first end of the stepped groove 311 and flows step by step toward the second end, thereby gradually reducing the water flow rate and mitigating the instantaneous impact of the water flow on the adjustment ring.

[0033] like Figure 4As shown, further, the second section includes a second body 33 and a second notch 34; a mounting hole 331 is provided on the second body 33, and a connecting rod 4 is passed through the rotating body 2, and both ends of the connecting rod 4 are arranged in the mounting hole 331 so that the adjustment ring 3 rotates with the rotating body 2.

[0034] in, Figure 4 for Figure 3 Schematic diagram of front and back flip.

[0035] Furthermore, when the second notch 34 rotates to the position corresponding to the water inlet chamber 11, the water flow can flow smoothly from the water inlet chamber 11 into the regulating chamber 12 and into the water flow path between the regulating ring 3 and the rotating body 2. The first notch 32 or the stepped groove 311 is above the first water outlet 131, and the water flow rate is larger at this time.

[0036] Furthermore, when the second body 33 rotates to the position corresponding to the water inlet chamber 11, the second body 33 partially blocks the channel between the water inlet chamber 11 and the regulating chamber 12. At this time, a smaller water flow will flow into the water flow path between the regulating ring 3 and the rotating body 2. The first body 31 and / or the stepped groove 311 are above the first water outlet 131, which further reduces the water flow.

[0037] That is, when the adjusting ring rotates to the second section to partially block the channel between the water inlet chamber and the adjusting chamber, the first section will also block the first water outlet or partially block the first water outlet, thereby reducing the water flow rate; when the adjusting ring rotates to the second notch corresponding to the channel between the water inlet chamber and the adjusting chamber, the first notch of the first section or the highest point of the stepped groove will correspond to the first water outlet, thereby increasing the water flow rate.

[0038] Furthermore, a second water outlet chamber 14 is provided in the valve body 1, the second water outlet chamber 14 is communicated with the regulating chamber 12, and a second water outlet 141 is provided in the second water outlet chamber 14; a shaft sleeve 5 is also provided in the valve body 1, the shaft sleeve 5 is sleeved on the outside of the rotating body 2 and installed in the valve body 1, and the shaft sleeve 5 abuts against the second water outlet 141 to close the second water outlet 141.

[0039] A spring 6 is provided between the rotating body 2 and the sleeve 5. One end of the spring 6 abuts against the rotating body 2, and the other end abuts against the sleeve 5. When the spring 6 is in a compressed state, the sleeve 5 abuts against the second water outlet 141 to close the second water outlet 141.

[0040] like Figure 5As shown, further, the flow regulating valve also includes a servo motor 7, which is electrically connected to the rotating body 2; the rotating body 2 includes a front end and a rear end, the front end is connected to the sleeve 5, and the rear end is connected to the servo motor 7; the servo motor 7 drives the rotating body 2 to rotate and move backward, so that the spring 6 is released and the sleeve 5 is separated from the second water outlet 141, and the second water outlet 141 is open.

[0041] When the motor reaches a certain power, the rotor 2 rotates relative to the valve body 1 and retreats relative to the valve body 1 in the direction of the servo motor 7. In the first stage of retreat, the spring 6 releases its elastic force, and the sleeve 5 still abuts the second water outlet 141, which is in a closed state. In the second stage of retreat, the sleeve 5 detaches from the second water outlet 141, and the second water outlet 141 is open. Water flows through the gap between the valve body 1 and the sleeve 5 to the second water outlet 141, and then flows out through the gap between the rotor 2 and the valve body 1. At the same time, in the second stage of retreat of the rotor 2, that is, when water is discharged from the second water outlet 141, the adjusting ring 3 partially blocks the first water outlet 131, so that the cross-sectional area of ​​the water flow path of the first water outlet 131 is equivalent to the cross-sectional area of ​​the second water outlet 141. At this time, the water output of the first water outlet 131 is equivalent to the water output of the second water outlet 141.

[0042] Among them, when the second body 33 rotates to the position corresponding to the water inlet chamber 11, the second body 33 partially blocks the channel between the water inlet chamber 11 and the regulating chamber 12, and the water flow in the second water outlet chamber 14 will also decrease, then the first water outlet chamber and the second water outlet chamber will synchronously reduce the water flow.

[0043] As an option, the flow regulating valve further includes a control device, which is electrically connected to the servo motor 7, and the servo motor 7 is electrically connected to the rotating body 2; a water flow sensor 8 is provided in the water inlet chamber 11, and the water flow sensor 8 is electrically connected to the control device.

[0044] The water flow sensor 8 detects the water flow signal and sends it to the control device. After receiving the detection signal, the control device sends a control instruction to the servo motor 7. The servo motor 7 drives the rotating body 2 to work, and the flow regulating mechanism starts to work.

[0045] The present application provides a flow regulating mechanism in the valve body, wherein the flow regulating mechanism includes a rotating body and an adjusting ring that rotates together with the rotating body, and the purpose of regulating the water flow of the first water outlet is achieved by the stepped groove structure on the outer wall of the adjusting ring; and the rotating body is installed in the valve body through a shaft sleeve. When the servo motor works at low power, the second water outlet is closed, and when the servo motor works at high power, the rotating body drives the rotating body backward to open the second water outlet. At this time, the first water outlet and the second water outlet can discharge water at the same time, achieving the effect of regulating the water flow through dual water outlets.

[0046] In a second aspect, the present application provides a flow regulating system, which includes a shell, in which a water pipe and a flow regulating valve as described in any one of the above items are provided; the flow regulating valve is connected to the water pipe.
