Description

Technical Field

[0001] The utility model relates to the technical field of three-way valves, in particular to a novel SF6 gas calibration three-way valve. Background Art

[0002] SF6, or sulfur hexafluoride, is a colorless, odorless inert gas that is primarily used as an insulating gas in electrical equipment, especially in high-voltage switchgear, to prevent arcing, electric shock, and fire. Due to its excellent insulating properties and chemical stability, SF6 is widely used in power systems such as substations and switchboards. However, SF6 is also a strong greenhouse gas with a much higher global warming potential than carbon dioxide, so its leakage must be strictly controlled.

[0003] In systems using SF6, three-way valves play a vital role. Not only are they used to connect and distribute gas flows in pipelines, but they can also quickly switch flow directions or close part of the path to facilitate system maintenance and safe operation. However, traditional three-way valves lack sufficient automation and real-time monitoring capabilities. In the event of SF6 gas leaks, traditional systems rely on manual detection and operation, which is not only slow to respond, but may not completely prevent catastrophic consequences in an emergency.

[0004] Therefore, those skilled in the art have proposed a novel self-adjusting and checking three-way valve for SF6 gas. Summary of the invention

[0005] In view of the above problems existing in the prior art, the main purpose of the utility model is to provide a novel SF6 gas calibration three-way valve.

[0006] The technical solution of the utility model is as follows: a novel SF6 gas calibration three-way valve, comprising a three-way body, three connecting pipes are fixedly connected to the outside of the three-way body, the angle between two corresponding connecting pipes is set to ninety degrees, a connecting flange is fixedly connected to the outside of the connecting pipe, a mounting plate is connected to the three-way body by screws, a pressure sensor is fixedly connected to the mounting plate, the sensing port on the pressure sensor extends to the interior of the three-way body, a driving motor is fixedly connected to the top of the three-way body, and an electrical connection structure is arranged between the pressure sensor and the driving motor.

[0007] Through the above technical means, the flow direction and sealing state of the tee body can be controlled by the movement of the driving motor, and the pressure sensor can sense the gas inside the tee body. When the gas pressure changes significantly, the driving motor can be controlled to work through the electrical connection structure.

[0008] As a preferred embodiment, the electrical connection structure includes a signal processor, a microcontroller module, a power module, a communication interface and an sound and light alarm module. The signal processor and the microcontroller module are arranged inside the drive motor, the communication interface is arranged inside the pressure sensor, the power module and the sound and light alarm module are arranged on the outside of the three-way body and the drive motor, the signal processor is electrically connected to the microcontroller module, the microcontroller module is electrically connected to the drive motor, the pressure sensor is electrically connected to the external sound and light alarm module through the communication interface, and the power module is electrically connected to the pressure sensor and the drive motor.

[0009] Through the above technical means, the pressure sensor is installed on the three-way body to continuously monitor the pressure changes in the valve. When a pressure abnormality (such as gas leakage) is detected, the pressure sensor sends a signal. This signal is first received and processed by the signal processor located inside the drive motor, and then passed to the microcontroller module also located inside the drive motor. The microcontroller module analyzes the data and determines whether measures need to be taken. If necessary, it sends a command to the drive motor to activate it to adjust or close the valve to prevent further gas leakage. The power module provides the necessary power to the pressure sensor, drive motor and other modules to ensure stable operation of the system. At the same time, in abnormal situations, it is sent to the sound and light alarm module through the communication interface of the pressure sensor, and the sound and light alarm module will be activated to alarm the operation and maintenance personnel and remind them to take corresponding measures.

[0010] As a preferred embodiment, the output end of the driving motor extends to the interior of the three-way body and is fixedly connected to a sealing ball head. Three flow holes are opened inside the sealing ball head. The three flow holes are interconnected, and the angle between two corresponding flow holes is set to ninety degrees.

[0011] Through the above technical means, the blocking effect can be achieved on the tee body through the blocking ball head.

[0012] As a preferred implementation, the interior of the tee body is a circular structure, and the blocking ball head is used in conjunction with the inner wall of the tee body.

[0013] Through the above technical means, the sealing effect of the sealing ball head can be guaranteed.

[0014] As a preferred implementation manner, a connecting line is provided between the pressure sensor and the driving motor.

[0015] Through the above technical means, the connecting line is used to transmit the signal of the pressure sensor to the drive motor.

[0016] Compared with the prior art, the advantages and positive effects of the utility model are:

[0017] The pressure sensor of the utility model can monitor the air pressure in the three-way body in real time, and once a pressure abnormality is detected, such as a gas leak, an emergency response is immediately initiated. Through the rapid processing of the signal processor and the microcontroller module, the drive motor receives the instruction and immediately adjusts the position of the blocking ball head to quickly cut off the gas flow and effectively block the leak point. This automatic blockade reduces the need for manual intervention, greatly improves the speed and efficiency of responding to emergencies, and greatly reduces safety risks. In addition, the activation of the sound and light alarm module provides an immediate alarm for operating and maintenance personnel, ensuring that personnel can take further measures in a timely manner, thereby ensuring the safety of equipment and the environment. These characteristics enable the device to more reliably protect the system in an emergency and avoid potential damage and losses. BRIEF DESCRIPTION OF THE DRAWINGS

An electrical connection structure is arranged between the pressure sensor 5 and the driving motor 7. The flow direction and the blocking state of the three-way body 1 can be controlled by the movement of the driving motor 7, and the pressure sensor 5 can sense the gas inside the three-way body 1. When the gas pressure changes greatly, the driving motor 7 can be controlled to work through the electrical connection structure.

[0027] like Figure 5 As shown, the electrical connection structure includes a signal processor, a microcontroller module, a power module, a communication interface and an acoustic and optical alarm module. The signal processor and the microcontroller module are arranged inside the drive motor 7, the communication interface is arranged inside the pressure sensor 5, the power module and the acoustic and optical alarm module are arranged outside the three-way body 1 and the drive motor 7, the signal processor is electrically connected to the microcontroller module, the microcontroller module is electrically connected to the drive motor 7, the pressure sensor 5 is electrically connected to the external acoustic and optical alarm module through the communication interface, the power module is electrically connected to the pressure sensor 5 and the drive motor 7, and the pressure sensor 5 is installed on the three-way body 1 to continuously monitor the pressure changes in the valve. When an abnormal pressure (such as gas leakage) is detected, the pressure sensor 5 will send a signal. This signal is first received and processed by the signal processor located inside the drive motor 7, and then transmitted to the microcontroller module also located inside the drive motor 7. The microcontroller module analyzes these data and determines whether measures need to be taken. If necessary, it will send a command to the drive motor 7 to activate it to adjust or close the valve to prevent further gas leakage. The power module provides the necessary power for the pressure sensor 5, the drive motor 7 and other modules to ensure stable operation of the system. At the same time, under abnormal circumstances, the pressure sensor 5 is sent to the sound and light alarm module through the communication interface, and the sound and light alarm module will be activated to send an alarm to the operation and maintenance personnel to remind them to take corresponding measures.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the output end of the driving motor 7 extends to the interior of the tee body 1 and is fixedly connected to a sealing ball head 9. Three flow holes 10 are opened inside the sealing ball head 9. The three flow holes 10 are interconnected, and the angle between the corresponding two flow holes 10 is set to ninety degrees. The sealing ball head 9 can achieve a sealing effect on the tee body 1.

The pressure sensor 5 is fixed on the mounting plate 4 of the tee body 1, and the sensing port 6 extends into the body to continuously monitor the gas pressure. Once the pressure sensor 5 detects a pressure abnormality, such as a gas leak, it will send a signal to the signal processor through the connecting line 8, which will process the signal and pass it to the microcontroller. The microcontroller module decides whether to activate the driving motor 7 after evaluation, and the driving motor 7 adjusts its position through the plugging ball head 9 connected to its output end, thereby closing the tee body 1 to control the flow direction or plugging state of the gas to prevent further leakage. At the same time, the sound and light alarm module will also be activated to remind the operator and maintenance personnel to deal with the problem in time through sound and light signals.
