Abstract
Description
Technical Field
[0001] This invention relates to the field of liquefied petroleum gas (LPG) cylinder safety technology, specifically to a device that can effectively record the disassembly and assembly marks of LPG regulators and cylinder valves. Background Technology
[0002] The bottled liquefied petroleum gas (LPG) cylinder valve consists of a regulator body, valve stem, valve core, pressure cap, sealing gasket, handwheel, etc. Installed on top of the cylinder, the valve closes the cylinder and connects to the pressure reducing valve. It is a crucial component of the cylinder, a necessary connection between the cylinder and the pressure reducing valve, and the main valve for filling, discharging, and shutting off LPG. The regulator and cylinder valve are connected with a reverse-locking mechanism. Before removing the regulator, the cylinder valve must be tightly closed by rotating the handwheel clockwise. Before reinstalling the pressure reducing valve, check the inlet sealing ring for deformation, detachment, or bottom sealing by rotating the handwheel counter-clockwise until the regulator is tightened and leak-free.
[0003] Currently, the bottled gas refilling market mainly manages the cylinders themselves, basically achieving one certificate per person, one code per cylinder, and one certificate per vehicle. All personnel are certified and work through a platform, accepting full digital supervision. The backend can view user information, gas purchase records, and cylinder circulation information, enabling traceability of both cylinder and user information. However, this cannot prevent issues such as cylinders being used in different locations, unauthorized refilling, lack of records for disassembling and assembling the cylinder and regulator handwheels, improper installation of the cylinder and regulator handwheels, unqualified regulators, and aging regulators. There is a lack of control measures over the source of the gas inside the cylinders, thus failing to fundamentally solve the risks associated with unauthorized gas refilling.
[0004] Therefore, how to provide a device that can effectively record the disassembly and assembly marks of liquefied gas pressure regulators and cylinder valves has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a device that can effectively record the disassembly and assembly traces of the liquefied gas regulator and the cylinder valve. The device can trigger the disassembly and assembly sensing device and sensor by rotating the cylinder handwheel connected to the regulator, sending forward and reverse information to the background and taking measures to cut off the regulator, so as to ensure that the cylinder and regulator handwheel are installed correctly and that gas bottled through abnormal channels cannot be used normally.
[0006] To achieve the above objectives, the present invention provides a device for effectively recording the disassembly and assembly traces of a liquefied petroleum gas (LPG) regulator and a gas cylinder valve, comprising: a regulator body, a fixed handwheel, and a disassembly / assembly sensing device; wherein, one end of the regulator body is connected to an inlet pipe, and the other end is connected to an outlet pipe, a threaded connecting pipe is connected to the inlet pipe, and a fixed handwheel is threadedly connected to the threaded connecting pipe; the inlet pipe is provided with an LPG inlet hole and a wire hole, the fixed handwheel is equipped with a disassembly / assembly sensing device, and a sensor is provided at the top of the wire hole near the fixed handwheel.
[0007] Furthermore, it also includes an electric switching valve, which is disposed within the body of the pressure regulator. The electric switching valve includes a valve core and a brushless motor, and the valve core is drivenly connected to the output end of the brushless motor.
[0008] Furthermore, it also includes a detection chip, which is electrically connected to the sensor and sends disassembly and assembly information to the data backend, outputs it to the control platform, or saves it to the recorder through the communication module.
[0009] Furthermore, it also includes a gas leak detector, which is electrically connected to the detection chip. When the sensor sends a disassembly / removal signal, the gas leak detector sends an alarm signal.
[0010] The beneficial effects of this invention are as follows:
[0011] This invention can trigger the disassembly and assembly sensing device and sensor by rotating the cylinder fixing handwheel connected to the pressure regulator, sending forward and reverse information to the background, and taking measures to cut off the pressure regulator to ensure that the cylinder and the pressure regulator handwheel are installed correctly, and to ensure that gas bottled through abnormal channels cannot be used normally.

[0023] like Figure 1-2 As shown, the present invention provides a device for effectively recording the disassembly and assembly traces of a liquefied petroleum gas (LPG) regulator and a gas cylinder valve, comprising: a regulator body 1, a fixed handwheel 12, and a disassembly / assembly sensing device; wherein, one end of the regulator body 1 is connected to an inlet pipe 2, and the other end is connected to an outlet pipe 3, a threaded connecting pipe is connected to the inlet pipe 2, and the fixed handwheel 12 is threadedly connected to the threaded connecting pipe; the inlet pipe 2 is provided with an LPG inlet hole and a wire hole 11, the fixed handwheel 12 is equipped with a disassembly / assembly sensing device, and a sensor is provided at the top of the wire hole 11 near the fixed handwheel.
[0024] The present invention also includes an electric switching valve 5, which is disposed within the pressure regulator body 1. The electric switching valve 5 includes a valve core 8 and a brushless motor 4, with the valve core 8 being drively connected to the output end of the brushless motor 4. The pressure regulator body 1 is linked with a detection chip and a communication module. The detection chip is used to detect abnormalities such as incomplete combustion of liquefied petroleum gas, leakage, or hose detachment / damage. The detection chip is connected to a mobile phone or PC via the communication module. The brushless motor is connected to the valve core via a threaded rod, and the brushless motor drives the screw to rotate, thereby realizing the up-and-down stroke of the valve core 8 of the electric switching valve 5, thus performing the function of opening and closing the pressure regulator body.
[0025] In this embodiment, the pressure regulator body 1 includes a pressure regulator body upper cover 1-1 and a pressure regulator body lower cover 1-2. The pressure regulator body upper cover 1-1 and the pressure regulator body lower cover 1-2 are connected by bolts and form a cavity inside. The middle of the inside of the pressure regulator body 1 is a pressure balancing mechanism. The upper and lower halves are isolated by diaphragms to ensure the sealing of the internal cavity of the pressure regulator body and prevent leakage.
[0026] In this embodiment, the top of the pressure regulator body 1 is provided with a circular threaded hole with a diameter of 1.75mm. An adjusting nut is threaded onto the circular threaded hole for adjusting the internal air pressure of the lower half of the pressure regulator body 1. The diaphragm part is fixedly mounted on the stainless steel tray 6, and the stainless steel tray 6 supports the pressure adjusting spring 7. The whole serves as a pressure balancing mechanism. The brushless motor 4 and the valve core of the electric switching valve 5 are installed in the lower chamber of the pressure regulator body 1. The brushless motor 4 is used to drive the valve core of the electric switching valve 5 to open and close. The pressure balancing mechanism, the brushless motor, and the valve core are used to adjust the internal pressure of the pressure regulator body 1 and have an electric shut-off function.
[0027] In this embodiment, a motor cover 9 is provided at the brushless motor 4. The wires of the brushless motor 4 and the detection chip are led out from the wire hole 10 on the rear side of the motor cover 9 and connected to external devices, thereby ensuring the information transmission and power supply of the voltage regulator body.
[0028] The brushless motor in this invention can be a vertical motor, such as... Figure 1 and Figure 3 As shown, a horizontal motor can also be used, such as... Figure 4 and Figure 5 As shown.
[0029] The present invention also includes a detection chip, which is electrically connected to the sensor and transmits disassembly and assembly information data to a data backend, outputs it to a control platform, or saves it to a recorder via a communication module.
[0030] The present invention also includes a gas leak detector, which is electrically connected to the detection chip. When the sensor sends a disassembly / removal signal, the gas leak detector sends an alarm signal.
[0031] When the regulator body is connected to bottled gas, the fixing handwheel, along with the threaded fixing, moves closer to the sensor at the wire hole. When the sensor and the disassembly / removal sensing device at the fixing handwheel reach a certain distance, the sensor transmits a signal through the wire hole. The sensor sends the disassembly / removal signal and the fixing handwheel installation and tightening signal to the data platform for recording. After receiving the signal from the external device, the data platform can remotely send manual instructions to the regulator to start the brushless motor to open or close the electric switch valve. The gas company or regulatory department can also verify this disassembly / removal to avoid risks caused by unauthorized disassembly / removal.
[0032] This invention can trigger a sensing device by rotating the cylinder handwheel connected to the pressure regulator, sending forward and reverse information to the backend. The backend records and saves the information and sends it to the gas company and relevant departments for verification. If abnormal disassembly or reassembly is confirmed, measures can be taken to precisely crack down on illegal gas vendors, thoroughly regulate the gas bottling market, cut off valves to ensure that the cylinder and pressure regulator handwheel are installed correctly, ensure that gas bottled through abnormal channels cannot be used normally, and take alarm signal reminder measures to prevent the use of cylinders and pressure regulators that are past their expiration date. This effectively strengthens management and control from the source of liquefied petroleum gas use, truly achieving inherent safety.
[0033] Currently, there is no way to prevent or effectively control the unauthorized disassembly and reassembly of bottled gas in the market. This invention uses a rotating handwheel to generate a signal with a sensor on the gas inlet pipe of the regulator, which is then transmitted to a data backend. The disassembly or reassembly is determined by the inconsistency in the displayed signal when disassembly or reassembly occurs. The disassembly and reassembly marks on the regulator are recorded in real time and reported to the data backend for storage. The data backend can not only view the user's specific address but also monitor user information, gas purchase records, cylinder circulation information, and the regulator's open / closed status in real time. Information such as the installation and removal status of the regulator and the tightening of the fixing handwheel, as well as whether the temperature and gas concentration at the regulator's location are normal, enables the traceability and auditability of cylinder and regulator installation / removal traces and user information. After receiving the cylinder and regulator installation / removal signals, the data backend matches them with the gas cylinder information. If a mismatch is found, it can be reported to the regulatory authorities. Based on the regulator signal information, the user can be accurately traced, and relevant departments can conduct on-site verification. This allows for control at the source of bottled gas and also avoids the risk of improper cylinder and regulator installation caused by human error.
[0034] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
