Description

Technical Field

[0001] This application relates to the field of valve technology, specifically a novel valve with a locking device. Background Technology

[0002] A user valve is a key device installed at the user's inlet to control the flow and shut-off of media such as water, gas, and heat. Like a "fluid manager" for a home or building, it plays a vital role in ensuring safety, regulating comfort, and enabling intelligent management.

[0003] Chinese utility model patent CN219735449U discloses an intelligent inlet valve. The purpose is to provide a simple, intelligently controlled inlet valve to solve the hydraulic balance problem between households. This utility model includes an intelligent inlet valve installed on the return water pipe at the front end of the household and a gateway installed in the building corridor. The gateway is wired to the intelligent inlet valve and wirelessly connected to a data platform. During operation, the gateway wirelessly receives valve opening adjustment commands from the data platform, then transmits them wired to the intelligent inlet valve, which adjusts the valve opening accordingly. Simultaneously, the intelligent inlet valve installed on the return water pipe of the heating system on the household side sends the collected supply and return water temperatures to the gateway, which then feeds them back to the data platform.

[0004] The aforementioned intelligent inlet valve adjustment process involves first collecting data through its own sensor module, then uploading it to a data platform via a gateway. The data platform then analyzes and calculates the data for each household and issues targeted valve opening and closing commands. Finally, each inlet valve, receiving the commands through the gateway, executes the valve opening and closing action. The entire process requires data to go through three levels of hops, each with transmission delays, resulting in redundancy, complexity, and slow response. Command issuance also requires reverse transmission, with cumulative delays potentially reaching minutes, making it difficult to meet emergency shut-off requirements. Furthermore, during use, the constantly changing real-time data necessitates continuous calculations by the data platform, placing a significant load on the monitoring platform. Simultaneously, as the number of users increases, the hardware cost of the monitoring platform will also increase exponentially.

[0005] Therefore, this application provides a novel door valve with a locking device to solve the above-mentioned problems. Utility Model Content

[0006] This application provides a novel household valve with a locking device, which aims to solve the problems mentioned in the background art, such as the difficulty of the existing intelligent household valve centralized cloud computing architecture in meeting real-time control requirements in a timely manner and the large load and hardware cost on the monitoring platform.

[0007] To achieve the above objectives, this application provides the following technical solution: a novel household valve with a locking device, comprising a valve body, a valve stem connected to a valve core, and a valve cover fitted over the valve stem and fixedly connected to the valve body. An electronic control mechanism with an output end connected to the valve stem is fixedly installed on the valve cover, and an integrated sensor for monitoring water supply temperature and flow rate is fixedly installed at the front end of the valve body.

[0008] The electrical control mechanism includes a drive box fixedly connected to the valve cover, a worm gear rotatably installed in the drive box and connected to the valve stem, a worm rotatably installed in the drive box and meshing with the worm gear, and a motor fixedly installed on the drive box and whose output end is connected to the worm.

[0009] A microprocessor is fixedly mounted on the drive box. The output of the integrated sensor and the input of the motor are both connected to the microprocessor. A power supply for powering the valve is fixedly mounted on the valve cover. Thus, through a dual mechanism of physical locking of the motor and electronic authorization verification by the microprocessor, unauthorized valve operation is prevented. The integrated sensor continuously monitors parameters such as fluid temperature and flow rate, and the data is transmitted to the microprocessor with low latency. The microprocessor calculates the valve opening degree in real time based on preset thresholds or dynamic models, without uploading to the cloud, thereby enabling timely valve action via the electronic control mechanism to meet emergency shut-off requirements.

[0010] Preferably, the microprocessor is connected to an external monitoring platform.

[0011] Preferably, a cover is fixedly installed on the drive box by screws.

[0012] Preferably, a lubrication groove communicating with the inside of the drive box is fixedly provided on the side of the drive box near the worm gear, and the lubrication groove is provided with grease that contacts the worm gear.

[0013] Preferably, a groove cover is fixedly installed on the lubrication groove by screws.

[0014] Preferably, the end of the worm gear away from the valve stem is fixedly connected to an extension rod that passes through the box cover, and a hand crank is fixedly installed at the other end of the extension rod.

[0015] This new type of valve with a locking device integrates sensors to continuously monitor parameters such as fluid temperature and flow rate. The data is transmitted to a microprocessor with low latency. The microprocessor calculates the valve opening degree in real time based on a preset threshold or dynamic model, without uploading to the cloud. This allows the valve to be executed in a timely manner through the electronic control mechanism, which can meet emergency shut-off needs.

[0016] This new type of valve with a locking device uses a dual mechanism of physical locking by a motor and electronic authorization verification by a microprocessor to prevent unauthorized valve operation and improve security.

[0017] This new type of valve with a locking device allows for manual operation of the valve in case of electrical control failure, providing an alternative solution and improving safety. Attached Figure Description

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] This embodiment provides a novel door valve with a locking device, such as... Figures 1-3 As shown, the new type of valve with a locking device includes a valve body 1, a valve stem 12 connected to the valve core, and a valve cover 11 fitted outside the valve stem 12 and fixedly connected to the valve body 1. An electronic control mechanism 2 with its output end connected to the valve stem 12 is fixedly installed on the valve cover 11. An integrated sensor 5 for monitoring water supply temperature and flow rate is fixedly installed at the front end of the valve body 1.

[0030] The electrical control mechanism 2 includes a drive box 21 fixedly connected to the valve cover 11, a worm gear 22 rotatably installed in the drive box 21 and connected to the valve stem 12, a worm 23 rotatably installed in the drive box 21 and meshing with the worm gear 22, and a motor 24 fixedly installed on the drive box 21 and whose output end is connected to the worm 23.

[0031] A microprocessor 4 is fixedly mounted on the drive box 21. The output terminal of the integrated sensor 5 and the input terminal of the motor 24 are both connected to the microprocessor 4. A power supply 6 for power supply is fixedly mounted on the valve cover 11.

[0032] In use, the drive box 21 integrates a worm gear 22, a worm 23, and a motor 24. The self-locking characteristics of the worm gear and worm enable precise control and physical locking of the valve opening and closing, preventing unauthorized operation. The motor 24 is directly driven by the microprocessor 4, replacing the traditional cloud computing command-issuing mode. The integrated sensor 5 monitors parameters such as water supply temperature and flow rate in real time, and the data is directly transmitted to the microprocessor 4. The microprocessor 4 has a built-in edge computing algorithm to perform data analysis and control logic judgment locally, directly driving the motor 24 to adjust the valve status, forming a "perception-decision-execution" closed loop. This eliminates the three-level jump delay of cloud computing, shortens the end-to-end response time to less than a second, and can achieve millisecond-level cutoff in emergencies. The monitoring platform only needs to handle abnormal event reports, reducing hardware costs.

[0033] It should be noted that the microprocessor 4 is connected to an external monitoring platform; the microprocessor 4 establishes bidirectional communication with the external monitoring platform through a standardized interface.

[0034] Furthermore, a cover 212 is fixedly installed on the drive box 21 by screws; the screw installation shortens the disassembly and assembly time and facilitates maintenance.

[0035] Furthermore, a lubrication groove 211 communicating with the inside of the drive box 21 is fixedly provided on the side of the drive box 21 near the worm 23. The lubrication groove 211 contains grease 25 that contacts the worm 23. A groove cover 2111 is fixedly installed on the lubrication groove 211 by screws. When the worm 23 rotates, the wedge-shaped groove wall pushes the grease 25 to the meshing tooth surface to form a thick oil film. The grease dropping point reaches 280°C, which is suitable for scenarios such as heating pipe networks, reducing the wear of worm gears and improving the service life of parts.

[0036] Furthermore, an extension rod 26 that penetrates the cover 212 is fixedly connected to one end of the worm gear 22 away from the valve stem 12, and a hand crank 3 is fixedly installed at the other end of the extension rod 26; by setting the hand crank 3, the valve can be opened and closed manually when the electric control mechanism 2 fails, providing an alternative solution and improving safety.

[0037] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
