Description

Technical Field

[0001] This utility model relates to the field of regulating valve technology, and specifically to a conveniently connected regulating valve with wireless control. Background Technology

[0002] With the popularization of IoT technology and smart homes, wirelessly controlled regulating valves are increasingly used in scenarios such as garden irrigation, balcony planting, and home aquariums. These valves allow users to remotely control the on / off state and flow of water via mobile apps, remote controls, etc., greatly improving the convenience of use.

[0003] For example, Chinese utility model patent CN223019449U discloses a regulating valve, including a valve body with a flow channel formed within it. The valve body also includes a sleeve, a valve core, and an actuator. The actuator, connected to the valve core, slides within the sleeve to regulate and cut off the flow channel. The characteristic feature is that adjusting components are slidably disposed at both ends within the sleeve. Each adjusting component includes an adjusting mesh and an adjusting block. The adjusting mesh has several evenly arranged adjusting holes. The adjusting block and the adjusting mesh are slidably connected. The valve core is connected to the adjusting block and controls the sliding of the adjusting component within the sleeve. When the actuator controls the sliding adjustment, the adjusting mesh first abuts against the bottom of the sleeve, and then the adjusting block slides tightly against the adjusting mesh and seals the adjusting holes. This utility model has the following advantages and effects: it can more precisely regulate the flow rate passing through the valve body.

[0004] Currently, wireless control regulating valves on the market have the following drawbacks in terms of pipeline connection methods: 1. Traditional threaded connection: This is the most common type of connection. During installation, Teflon tape needs to be wrapped around the threads and tightened using a wrench or similar tool. This method has significant drawbacks: Installation is cumbersome: It is not user-friendly for ordinary users, requiring the preparation of tools and mastery of certain operating skills, and the installation process is time-consuming and laborious.

[0005] Risk of damage: Improper torque during tightening may cause the valve body (especially the part with built-in precision electronic components) to twist and deform, resulting in damage to internal parts or communication failure.

[0006] Inconvenient disassembly: After long-term use, the threads may seize due to scale or rust, making maintenance and replacement extremely difficult.

[0007] High space requirements: In narrow spaces, wrenches are difficult to maneuver, increasing the difficulty of installation.

[0008] 2. Existing quick-connect method: To solve the problems of threaded connections, some products use push-in quick-connect fittings. Users simply insert the pipe and connect it via internal clips and O-rings. While this method is an improvement, it still has shortcomings: Disassembly is inconvenient: Most quick-connect fittings require the user to press a release ring firmly to pull out the pipe, which is still difficult to operate in confined spaces or when the pipe is rigid. Utility Model Content

[0009] The purpose of this invention is to provide a conveniently connected regulating valve with wireless control to solve the problems mentioned in the background art.

[0010] To achieve the above objectives, this utility model provides the following technical solution: A convenient connection regulating valve with wireless control includes a valve body, in which a flow channel is formed, and a sleeve, a valve core, a valve stem, and an actuator are provided. The actuator is equipped with a wireless control module and drives the valve core through the valve stem, so that the valve core slides in the sleeve to adjust or cut off the flow channel. The fluid interface of the valve body is provided with a quick-connect structure for quick connection and locking with external pipelines without tools.

[0011] Furthermore, the quick-connect structure includes a connecting frame fixed to the fluid interface of the valve body, and a connecting pipe for connecting to an external pipeline, wherein a limiting locking component is provided between the connecting frame and the connecting pipe.

[0012] Furthermore, the limiting and locking assembly includes a matching limiting groove and a limiting tube, wherein the limiting groove is formed on the side of the connecting frame and the limiting tube is fixed to the side of the connecting tube.

[0013] Furthermore, the limiting and locking assembly also includes a locking steel ball and an elastic drive member. When the connecting frame and the connecting tube are engaged, a first locking groove and a second locking groove are formed at their corresponding positions, which together constitute a spherical space to accommodate the locking steel ball. The elastic drive member is disposed on the connecting frame and is used to provide radial clamping force to the locking steel ball, so that it is partially stuck into the spherical space.

[0014] Furthermore, the elastic drive component includes an annular groove formed on the outside of the connecting frame, a spring disposed in the annular groove, and a movable frame driven by the spring and capable of sliding along the annular groove, wherein the inner sidewall of the movable frame contacts the outer side of the locking steel ball.

[0015] Furthermore, a support frame is fixedly installed on the top of the sleeve, and a marking mechanism is fixedly installed on the side of the support frame. The marking mechanism includes an indicator plate, which is fixedly installed on the side of the support frame. A fixing frame is fixedly installed on the outer side of the valve stem, and an arrow plate is fixedly installed on the side of the fixing frame near the indicator plate.

[0016] Furthermore, a dynamic sealing structure is provided between the sleeve and the valve stem. The dynamic sealing structure includes at least one sealing groove formed on the inner wall of the sleeve, and a sealing ring embedded in the sealing groove.

[0017] Furthermore, the sealing ring is a U-shaped or Y-shaped sealing ring made of polyurethane or PTFE material, the surface of the valve stem that contacts the sealing ring is a high-gloss chrome-plated polished surface, and the sleeve is provided with a pressure relief hole, which is located between two adjacent sealing rings.

[0018] The beneficial effects of this utility model are as follows: 1. This utility model features a quick-connect structure at the fluid interface of the valve body. Through the cooperation of the connecting bracket and connecting pipe, combined with a limiting locking component, it achieves "tool-free quick assembly and disassembly": the radial positioning of the limiting groove and limiting pipe ensures coaxiality during docking, preventing valve core jamming due to installation misalignment; the spherical space formed by the locking steel ball and the first and second locking grooves, along with an elastic drive component, allows locking and unlocking to be completed simply by pushing / pulling the movable bracket, eliminating the need for wrenches, flange bolts, or other tools. Compared to traditional flange or threaded connections, the installation / disassembly time for a single device is reduced from over 30 minutes to 2-3 minutes. Even non-professionals can operate it, significantly reducing installation labor and time costs. It is particularly suitable for fluid pipeline scenarios requiring frequent replacement or maintenance (such as reagent delivery pipelines in the chemical industry and pipelines in smart home water purifiers).

[0019] 2. This utility model utilizes a dynamic sealing structure between the sleeve and the valve stem, preferably employing U-shaped or Y-shaped polyurethane or PTFE sealing rings to address the reciprocating motion of the valve stem. These materials combine excellent wear resistance and a low coefficient of friction, and when combined with a high-gloss chrome-plated valve stem surface, they significantly reduce motion resistance and wear while ensuring effective sealing, thus extending the service life of the seals and actuator. Simultaneously, a pressure relief hole is provided between the two sealing rings. This design allows leaked media to be directed to the outside (or low-pressure area) in the event of accidental failure of the first seal, rather than being directly flushed out of the second seal. This serves both as a safety warning, reminding users to perform timely maintenance, and as a safety barrier, greatly improving the reliability and safety of the product and preventing the escalation of leakage accidents.

[0027] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with... Figures 1-5 The present invention will be further described below.

[0028] This convenient wireless control regulating valve includes a valve body 1 with a flow channel inside, and is equipped with a sleeve 2, a valve core 3, a valve stem 4, and an actuator 5. The actuator 5 has a wireless control module and drives the valve core 3 through the valve stem 4, causing the valve core 3 to slide within the sleeve 2 to adjust or cut off the flow channel. Specifically, by integrating the wireless control module into the actuator 5, users can remotely control the valve via a mobile app, remote control, or smart home system, achieving intelligent valve management. This not only brings great operational convenience but also enables advanced functions such as timed irrigation and scene linkage (e.g., automatic valve shut-off in "away mode"), achieving the dual goals of water conservation and intelligent management. The fluid interface of the valve body 1 is equipped with a quick-connect structure for tool-free quick connection and locking with external pipelines. Specifically, the quick-connect structure significantly reduces installation labor and time costs, making it particularly suitable for fluid pipeline scenarios requiring frequent replacement or maintenance (such as reagent delivery pipelines in the chemical industry and pipelines in smart home water purifiers).

[0029] The quick-connect structure includes a connecting frame 10 fixed at the fluid interface of the valve body 1, and a connecting pipe 11 for connecting to an external pipeline. A limiting locking assembly 12 is provided between the connecting frame 10 and the connecting pipe 11. The limiting locking assembly 12 includes a matching limiting groove 1201 and a limiting tube 1202. The limiting groove 1201 is opened on the side of the connecting frame 10, and the limiting tube 1202 is fixed to the side of the connecting pipe 11. Specifically, by inserting the limiting tube 1202 of the connecting pipe 11 into the limiting groove 1201 of the connecting frame 10, the connecting frame 10 and the connecting pipe 11 can be connected together.

[0030] The limiting locking assembly 12 also includes a locking steel ball 1208 and an elastic drive member. When the connecting frame 10 and the connecting pipe 11 are engaged, a first locking groove 1206 and a second locking groove 1207 are formed at their corresponding positions, which together constitute a spherical space to accommodate the locking steel ball 1208. The elastic drive member is disposed on the connecting frame 10 and is used to provide radial clamping force to the locking steel ball 1208, so that it is partially inserted into the spherical space. The elastic drive member includes an annular slide groove 1203 opened on the outside of the connecting frame 10, a spring 1204 disposed in the annular slide groove 1203, and a movable frame 1205 driven by the spring 1204 and slidable along the annular slide groove 1203. The inner sidewall of the movable frame 1205 is in contact with the outer side of the locking steel ball 1208. Specifically, when the movable frame 1205 is pushed away from the first locking groove 1206, the locking steel ball 1208 will disengage from the second locking groove 1207 and enter the first locking groove 1206 and the outer side of the first locking groove 1206. At this time, the locking of the limiting tube 1202 can be released, thereby separating the connecting frame 10 and the connecting tube 11. When the movable frame 1205 is released, under the elastic force of the spring 1204, the movable frame 1205 will move towards the first locking groove 1206, thereby pushing the locking steel ball 1208 into the first locking groove 1206 and the second locking groove 1207, thereby fixing the connecting frame 10 and the connecting tube 11. Disassembly and assembly can be performed without tools such as wrenches and flange bolts.

[0031] A support frame 6 is fixedly installed on the top of the sleeve 2, and an indicator mechanism 7 is fixedly installed on the side of the support frame 6. The indicator mechanism 7 includes an indicator plate 701, which is fixedly installed on the side of the support frame 6. A fixing frame 702 is fixedly installed on the outside of the valve stem 4, and an arrow plate 703 is fixedly installed on the side of the fixing frame 702 near the indicator plate 701. Specifically, when the valve stem 4 moves up and down, it will drive the fixing frame 702 and the arrow plate 703 to move up and down together. With the help of the indicator plate 701, it is convenient for the staff to understand the internal flow channel of the valve body 1.

[0032] A dynamic sealing structure is provided between the sleeve 2 and the valve stem 4. This structure includes at least one sealing groove 8 formed on the inner wall of the sleeve 2, and a sealing ring 9 embedded within the sealing groove 8. The sealing ring 9 is a U-shaped or Y-shaped sealing ring made of polyurethane or PTFE. The surface of the valve stem 4 in contact with the sealing ring 9 is a high-gloss chrome-plated polished surface. A pressure relief hole is provided on the sleeve 2, located between two adjacent sealing rings 9. Specifically, the U-shaped or Y-shaped sealing ring 9 made of polyurethane or PTFE has excellent wear resistance and a low coefficient of friction. Combined with the high-gloss chrome-plated surface of the valve stem 4, it significantly reduces movement resistance and wear while ensuring effective sealing, extending the service life of the seals and actuator 5. Furthermore, the pressure relief hole between the two sealing rings 9 directs the leaked medium to the outside (or low-pressure area) in case of accidental failure of the first seal, rather than directly flushing out the second seal. This serves both as a safety warning, reminding users to maintain the seal in a timely manner, and as a safety barrier, greatly improving the reliability and safety of the product and preventing the escalation of leakage accidents.

[0033] Working principle and usage process of this utility model: Phase 1: Pipeline Installation and Connection Prepare the pipes: Ensure that the cuts of the external pipes to be connected are smooth and free of burrs.

[0034] Unlock the quick-installation structure: Hold the movable bracket 1205 on the outside of the connecting bracket 10 with your hand and push it axially toward the valve body 1.

[0035] The movable frame 1205 compresses the spring 1204 and moves backward, so that its inner sidewall no longer presses against the locking steel ball 1208.

[0036] The locking ball 1208 loosens within the internal space, exits from the second locking groove 1207, and rolls to the outer area of ​​the first locking groove 1206. At this point, a "unlocked" feedback can be heard or felt.

[0037] Alignment insertion: Align the limiting tube 1202 on the connecting tube 11 with the limiting groove 1201 on the connecting frame 10.

[0038] Gently push it in so that the limiting tube 1202 is fully inserted into the bottom of the limiting groove 1201, achieving preliminary axial positioning and centering.

[0039] Locked connection: Release the movable frame 1205. Under the restoring force of the spring 1204, the movable frame 1205 slides forward.

[0040] The inner wall of the movable frame 1205 presses against all the locking steel balls 1208, forcing them to move radially inward.

[0041] A portion of the locking steel ball 1208 is embedded in the first locking groove 1206 of the connecting bracket 10, while the other portion is firmly locked into the second locking groove 1207 of the connecting tube 11, forming a complete spherical locking space.

[0042] When you hear a clear "click" and the movable bracket 1205 can no longer be easily pushed, it indicates that the connection has been locked. The entire process requires no tools.

[0043] Phase Two: Wireless Operation and Status Monitoring Power supply and networking: Connect actuator 5 to a power source, such as by installing a battery or connecting to a low-voltage power supply, and pair it with your home wireless network and the corresponding mobile app according to the instruction manual.

[0044] Remote / wireless control: Remote operation: Open the mobile app to remotely control the valve to open or close, or precisely adjust the flow rate.

[0045] Scheduled tasks: Set up scheduled tasks in the app, such as automatically opening the valve to irrigate the garden every morning from 7:00 to 7:15.

[0046] Smart linkage: Integrate the valve into the smart home system to achieve scene linkage. For example, when "away mode" is set, the smart system automatically turns off the water valve.

[0047] Local status confirmed: At the valve site, staff can directly confirm the valve status by observing the marking mechanism 7.

[0048] The valve stem 4 drives the fixed bracket 702 and the arrow plate 703 to move up and down. Their positions relative to the scale of the indicator plate 701 visually indicate whether the valve is in the "open", "closed" or "adjusting" state.

[0049] Phase Three: Disassembly, Maintenance, and Safety Assurance Safe disassembly: Repeat the operation of [Phase 1, Step 2] to push the movable frame 1205 to the unlocked position.

[0050] At this point, the locking force disappears, and the connecting tube 11 can be easily pulled out of the connecting bracket 10, achieving quick separation.

[0051] Sealing system maintenance: The unique dynamic sealing structure ensures long-term sealing performance during valve stem 4 movement. The wear-resistant sealing ring 9, combined with the high-gloss valve stem 4, results in extremely low wear and requires virtually no maintenance.

[0052] If a trace amount of media leaks from the pressure relief hole, this is an important warning signal, indicating that the first sealing ring 9 may have failed. In this case, the valve should be closed immediately and inspection and maintenance performed. The second sealing ring 9 will still provide a safety guarantee and prevent the leakage from expanding.

[0053] Troubleshooting: If the wireless control fails, the actual status of the valve can be determined first through the local marking mechanism 7.

[0054] Check the power supply and network connection of actuator 5.

[0055] If there is a problem with the mechanical connection, you can usually check whether the locking ball 1208 is flexible and whether the spring 1204 is faulty.

[0056] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
