Description

Technical Field

[0001] This utility model relates to the field of drain valve sensor technology, specifically to a dual pressure sensor for an IoT anti-theft drain valve. Background Technology

[0002] The IoT-enabled smart electric regulating valve is a high-tech product that integrates sensors, controllers, actuators, and communication modules. It can automatically adjust the valve opening based on signals from industrial automation control systems, thereby achieving precise control of process parameters such as flow rate, temperature, and pressure of the medium in the pipeline. At the same time, through IoT technology, this regulating valve can achieve real-time communication with remote monitoring systems, enabling remote data transmission and monitoring.

[0003] However, existing IoT valves are difficult to pressure measure and pressure sensors are inconvenient to install; existing valves are mostly manufactured by casting or cold heading processes, which are expensive, complex in process, and mostly made of cast iron and brass. Utility Model Content

[0004] The technical problem this utility model aims to solve is the difficulty in measuring pressure in existing IoT valves and the inconvenience in installing pressure sensors. Furthermore, existing valves are mostly manufactured using casting or cold heading processes, resulting in high costs, complex processes, and materials such as cast iron and brass.

[0005] To solve the above problems, the technical solution adopted by this utility model is a dual pressure sensor for an IoT anti-theft drain valve, including a plastic shell. A PCB is fixed inside the plastic shell near the top. A speed reducer is fixed inside the plastic shell below the PCB. A valve is connected below the speed reducer. The valve includes a valve body with a valve ball in the middle of the inner side of the valve body. A valve stem is connected to the lower end of the speed reducer. The bottom end of the valve stem is connected to the valve ball. A valve stem bushing is sleeved on the outer side of the valve stem. An adapter plate is fixedly connected to the bottom end of the plastic shell at the valve stem. A pair of sensor bases are fixed to the bottom end of the valve body. A sensor device is rotatably connected to the sensor bases via threads.

[0006] As a further embodiment of this invention, a polytetrafluoroethylene gasket and an O-ring are provided on the outside of the valve ball to provide a seal.

[0007] As a further embodiment of this invention, a plurality of valve stem sealing rings are fitted on the outer side of the valve stem to provide a seal.

[0008] As a further embodiment of this utility model, valve plugs are provided at both ends of the valve body for installation or sealing of the valve body.

[0009] As a further embodiment of this invention, the speed reducer is electrically connected to an external power source.

[0010] Compared with the prior art, the advantages of this utility model are as follows: Based on the traditional Internet of Things electric valve, this application adds a pressure sensor that is linked with the valve. The device's microcontroller program judges the pressure value. When the pressure value suddenly drops below the normal value, it is determined that the user has released hot water without authorization. The valve immediately closes and sends the valve's current status to the cloud system for manual intervention. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides a technical solution to address the existing problems mentioned in the background art.

[0019] Combined with appendix Figure 1-3It can be seen that the device includes a plastic shell 1, a PCB 2 fixed inside the plastic shell 1 near the top, a speed reducer 3 fixed inside the plastic shell 1 below the PCB 2, a valve 4 connected below the speed reducer 3, the valve 4 includes a valve body 4.1, a valve ball 4.7 in the middle of the inner side of the valve body 4.1, a valve stem 4.10 connected to the lower end of the speed reducer 3, the bottom end of the valve stem 4.10 connected to the valve ball 4.7, a valve stem bushing 4.3 sleeved on the outside of the valve stem 4.10, an adapter plate 4.9 fixedly connected to the bottom of the plastic shell 1 at the valve stem 4.10, and a pair of sensor bases 4.4 fixed to the bottom of the valve body 4.1. A sensor device 5 is threadedly rotatably connected to the sensor base 4.4. With a pair of sensor devices 5, the two sensor devices 5 can better sense the pressure changes at the inlet and outlet when the valve is closed. The algorithm has more options compared to a single pressure sensor, but it also brings an increase in cost.

[0020] The valve ball 4.7 is provided with a polytetrafluoroethylene gasket 4.5 and an O-ring 4.6 on the outside for sealing. The valve stem 4.10 is fitted with several valve stem 4.10 sealing rings on the outside for sealing. Both ends of the valve body 4.1 are provided with valve plugs 4.2 for installing or sealing the valve body 4.1. The reducer actuator 3 is electrically connected to an external power supply.

[0021] This application is an improvement based on a mechanical anti-theft drain valve. The principle of the mechanical anti-theft drain valve is as follows: the flow rate is controlled by the central valve stem and the float. When the valve is in a depressurization state, the float rises and closes the outlet, realizing the automatic locking function. When the valve pressure is restored, the float falls back and opens the outlet.

[0022] This application discloses an IoT anti-theft drain valve based on the principle of a mechanical anti-theft drain valve. The valve body 4.1 uses a valve ball 4.7, and a pressure sensor device 5 is located at the bottom of the valve body 4.1. The valve ball 4.7 has a connecting hole on its outlet side. When the water pressure deviates from the normal value, the system uses the normal value provided by the host computer to assist in determining whether pressure is being released. This triggers automatic valve closure via PCB2. When the pressure recovers, the valve can be opened automatically either through remote manual intervention or by manual judgment.

[0023] One pressure sensor device 5 requires valve 4 to use the normal pressure defined by the cloud system as the reference pressure. When the pressure changes compared to this pressure, it is considered as a pressure relief. If there is no normal reference pressure, it will lead to failure to close the valve or incorrect valve closure.

[0024] To avoid misjudgment, enabling or disabling the linkage function should be linked to the payment function. That is, this function should only be enabled for users who have not paid, while users who have paid should not be judged by default, but can optionally retain this function.

[0025] During the non-heating season: the valve should remain in the state it was in before the end of the heating season. The pressure linkage function should be suspended during this period. After the normal heating season begins, the function should be restarted. The start and stop times should be determined by the cloud system.

[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
