[0023] The present application provides an efficient and safe pipeline liquid pressure and flow detection device, such as Figure 1 As shown, it includes an air pressure sensor 1, a connecting air pipe 2 and a processor 4. One end of the connecting air pipe 1 is connected to the air pressure sensor 1, and the other end is used to connect to the upper part of the inner portion of the pipeline to be detected.

[0024] When liquid passes through a pipe, gravity separates the liquid and gas, causing the gas to accumulate at the top of the pipe and the liquid to settle at the bottom. This application uses a connecting air pipe to connect the inside of the pipe to the air pressure sensor. Different flow rates compress the air in the connecting air pipe at the pipe joint to varying degrees, converting the water pressure into air pressure. The air pressure signal is detected by the air pressure sensor.

[0025] The processor is electrically connected to the air pressure sensor, and the data collected by the air pressure sensor is transmitted to the processor in real time. The processor obtains the liquid pressure of the pipeline to be tested through simple calculation and analysis based on the sensor feedback information, and then converts the actual liquid flow rate through a specific algorithm based on the corresponding pressure.

[0026] The pipeline liquid pressure and flow sensors in the prior art are generally directly installed on the pipeline, in direct contact with the liquid, and are easily affected by corrosion and impurities in the liquid, which affects the detection accuracy and service life. However, the air pressure sensor and processor in the device provided by the present application are installed outside the pipeline and are not in direct contact with the liquid, thus avoiding interference from external adverse factors such as corrosion and impurities, and have good safety and high accuracy. Moreover, the pressure and flow of the liquid in the pipeline can be detected at one time through a single air pressure sensor, which is highly efficient. Therefore, the pipeline liquid pressure and flow detection device provided by the present application has the advantages of simple structure, low cost, high safety, and easy maintenance. It is more suitable for a wide range of use scenarios with cost requirements and is suitable for large-scale use.

[0027] The pipe to be tested in this application can be a conventional water pipe, water outlet, valve or other component with a certain cross-section for liquid to pass through. The shape, length and inner diameter of the connecting air pipe can be adjusted according to actual needs to be able to connect the pipe to be tested and the air pressure sensor.

[0028] Preferably, both ends of the connecting air pipe 2 are connected to the air pressure sensor 1 and the pipeline to be detected by a connector 3. Furthermore, the connector is a quick connector that can quickly connect or disconnect the two ends of the connecting air pipe from the air pressure sensor and the pipeline to be detected. With this arrangement, the connecting air pipe can be disconnected when needed, making it easier to carry the detection device.

[0029] Preferably, the connector is a pneumatic quick connector, which is reliable to install, easy to use, has good air tightness, and the connecting air pipe is not easy to loosen or fall off.

[0030] Preferably, the air pressure sensor 1 is a high-precision sensor that can accurately measure tiny pressure changes, monitor the pipeline air pressure status in real time and accurately, and improve the measurement accuracy of the system.

[0031] Preferably, the connecting air pipe 2 is made of nylon, which is resistant to high and low temperatures and has good corrosion resistance, thereby ensuring the reliability of the device.

[0032] Preferably, the processor 4 also includes a temperature compensation function to ensure that accurate measurement results can be obtained under different temperature conditions.

[0033] In order to isolate the air pressure sensor and the processor from the influence of the external environment, the detection device provided in the present application also includes a package body, and the air pressure sensor 1 and the processor 4 are both located in the package body, thereby effectively protecting the air pressure sensor and the processor.

[0034] Further preferably, the air pressure sensor 1 and the processor 4 are separately arranged and located at different positions of the package body, which can prevent the air pressure sensor and the connecting air pipe from affecting the processor due to poor airtightness.

[0035] As described above, preferably, a connector is provided on the package body, one end of the connector is located inside the package body and connected to the air pressure sensor 1 , and the other end of the connector is exposed to facilitate connection with the connecting air pipe 2 .

[0036] Further preferably, the connector is a pneumatic quick connector.

[0037] The package body can be made of high-strength materials such as conventional plastic packaging shells.

[0038] Valves are needed in agricultural irrigation to control the connection or interruption of irrigation water flow and adjust the flow rate. In the existing technology, electric valves are generally used to facilitate control. The electric valve includes a valve body, a valve core located in the valve body, and a valve stem connected to the valve core. The valve body includes at least one water inlet end and at least one water outlet end. The electric valve is also provided with an electric actuator to drive the valve stem to rotate, thereby driving the valve core to rotate to achieve the above functions.

[0039] The detection device provided in this application can be applied to electric valves to detect water flow pressure and flow, and automatically drive the valve stem and valve core to rotate in combination with an electric actuator to achieve the purpose of automatically adjusting water flow pressure and flow. The specific description is as follows:

[0040] The electric actuator 6 serves as the package, with the air pressure sensor and processor housed within it. A quick connector 3 is provided on the actuator housing for connecting the air pressure sensor 1 to the air pipe 2. The processor 4 can be integrated into the actuator's control board, and the power supply within the electric actuator 6 can also power the air pressure sensor.

[0041] A quick connector 3 is provided on the water outlet of the electric valve 5. When there are multiple water outlets, each water outlet is provided with a quick connector. At the same time, a corresponding number of air pressure sensors and connectors are provided on the electric actuator.

[0042] During use, connect the two ends of the air pipe to the quick connectors on the electric valve and the electric actuator. The air pressure sensor and processor monitor the water pressure and flow at the outlet in real time, thereby determining the irrigation pressure and flow. The control board then drives the valve stem and valve core to automatically adjust the operating state of the electric valve based on the detection results. If the irrigation flow fluctuates, the air pressure sensor provides timely detection and feedback, allowing the electric valve to quickly respond and adjust the liquid flow, avoiding system instability caused by flow fluctuations and improving system reliability and stability.

[0043] The water inlet end of the electric valve 5 may also be provided with a quick connector to detect the water inlet pressure and flow of the electric valve.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.
