Technical Field
[0001] This utility model belongs to the field of valve switching detection, specifically a valve switching detection device. Background Technology
[0002] An air valve is a device that controls the flow direction or switches the airflow path. It is mainly used for airflow regulation in industrial pipeline systems, making it an indispensable part of industrial pipelines. However, air valves have some difficult-to-solve problems in actual use: 1. Incompatibility may occur when connecting the air valve to the pipeline. For example, the air valve may be round while the pipeline is rectangular, or vice versa. Therefore, there is a lack of a connector that automatically adapts to both the pipeline and the air valve; 2. After a period of use, the air valve may become damaged and leak air, but maintenance personnel may not be able to detect the leakage problem in time, resulting in significant losses.

[0015] The present invention will be further described below with reference to the accompanying drawings and some embodiments.
[0016] exist Figures 1-3A damper switching and detection device is disclosed. The damper is a common electric damper used to regulate gas flow. It is mainly used in ventilation and environmental protection pipeline systems in building materials, metallurgy, and power industries. The device includes a main body 1, which includes a switching component and a detection component. The detection component is installed on the switching component. The switching component includes a rectangular connecting block 2 and a circular ventilation pipe 3. The connecting block 2 has a circular hole 201 at its center for the ventilation pipe 3 to pass through. The circular hole 201 is connected and fixed to the periphery of the ventilation pipe 3. The ventilation pipe 3 can be installed in the circular hole 201 by welding or other methods. To prevent air leakage, connecting block 2 and ventilation pipe 3 are on the same vertical plane, meaning they are of different lengths. Being on the same vertical plane facilitates connection to different types of pipes or valves. Both the connecting end face of connecting block 2 and the connecting end face of ventilation pipe 3 are equipped with flange assemblies 4 for flange connection. The switching assembly is installed on the valve and pipe via the flange assembly 4. Connecting block 2 can have a structure that is thicker on both sides and thinner in the middle, allowing the ventilation pipe 3 some room to move, facilitating connection between the ventilation pipe 3 and the pipe or valve. The detection assembly includes components for detecting the airflow force of ventilation pipe 3. The system includes a wind detector 5, a wind aberration alert component 6, and a microcontroller 7. The wind detector 5 is installed inside the ventilation duct 3 for real-time wind monitoring. The output of the wind detector 5 and the output of the air valve switch are electrically connected to the input of the microcontroller 7. The output of the microcontroller 7 is connected to the input of the alert component 6. The wind threshold of the wind detector 5 can be determined according to actual conditions. The threshold can be changed in the background or programmed through the microcontroller 7. The microcontroller 7 is a common programmable microcontroller 7; the specific model is not limited and can be selected according to actual needs, for example, A. Microcontrollers such as T89C2051 or TMS320VC5509A are used. The microcontroller 7 is electrically connected to each component. It receives and transmits signals. When the valve is closed and the wind force exceeds the threshold, the microcontroller 7 will transmit the clamping information to the reminder component 6, so that the reminder component 6 can sound an alarm for easy maintenance. In use, depending on the shape of the pipe, it can be connected to the flange assembly 4 on the connecting block 2 or the flange assembly 4 on the ventilation pipe 3. After the air valve is closed, if the wind force detector 5 detects that the wind force is still in an abnormal state, the reminder component 6 will issue a reminder.
[0017] In this embodiment, the reminder component 6 includes an alarm or a wireless signal transmitter, which is electrically connected to the microcontroller 7. The alarm or wireless signal transmitter sends an abnormal signal to provide a reminder. For example, the alarm can provide a reminder through sound and light, and the wireless signal transmitter can send abnormal information to a mobile terminal or control center. The alarm can be a common alarm indicator light, and the wireless signal transmitter can be a common wireless signal transmission device. The specific model is not limited and can be selected according to the actual situation, such as the ST58T8G series model or the ST9500DBH model wireless signal transmitter.
[0018] In this embodiment, the flange assembly 4 includes a flange plate 401 and a plurality of flange holes 402. The plurality of flange holes 402 are evenly installed on the flange plate 401. The flange plate 401 is installed on the connecting block 2 and the ventilation pipe 3. The flange plate 401 can be installed on the ventilation pipe 3 and the connecting block 2 by welding or other means. The switching assembly is installed on the air valve by screws or other components passing through the flange holes 402.
[0019] In this embodiment, the ventilation pipe 3 and the connecting block 2 are provided with a groove for placing the detection component. The detection component can be installed in the groove by means of adhesive, screws or other means to prevent the detection component from being blown off. The bottom end of the groove is located on the connecting block 2, and the top end passes through the ventilation pipe 3 and faces the inside of the ventilation pipe 3. The ventilation pipe 3 and the groove are connected and sealed around the groove by means of welding or other means to prevent air leakage.
[0020] In this embodiment, a sealing ring is provided at the connection between the ventilation pipe 3 and the connecting block 2 to reduce air leakage.
[0021] In this embodiment, the detection component also includes a storage battery, which is electrically connected to the microcontroller 7. The storage battery provides power to the detection component. After a period of use, the storage battery needs to be replaced or charged.
[0022] In this embodiment, the wind detector 5 is a common wind flow testing device. The specific model is not limited and can be selected according to the actual situation, such as the 485-type ABS wind speed sensor, WD4120-wind speed sensor, etc.
[0023] In this embodiment, the control circuit of this utility model is a common circuit in the field of circuits. The device of this utility model can be connected to an external power source or a built-in battery through a power cord to provide power to the device. Those skilled in the art can implement it, so it will not be described in detail here.
[0024] In practical implementation, this utility model is used by installing it according to the actual situation of the pipe and the air valve. For example, if the pipe is square, it is connected to the pipe through the flange assembly 4 on the connecting block 2; if the pipe is round, it is connected to the pipe through the flange assembly 4 on the ventilation pipe 3. Similarly, it can also be connected to the switching assembly according to the shape of the air valve, so that air valves and pipes of different shapes can be connected. During the use of the air valve, the wind power detector 5 detects the air volume of the air valve. When the air valve is closed and the air volume exceeds the threshold, it proves that the air valve is damaged. Then the reminder assembly 6 reminds the user to replace the air valve.
[0025] It is worth noting that in the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified. In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model patent is defined by the appended claims rather than the foregoing description.
