Description

Technical Field

[0001] This utility model relates to the field of gas regulation technology, specifically to a pressure regulator with a fault self-diagnosis function. Background Technology

[0002] A pressure regulator is a key device used to regulate gas pressure. It is typically installed between the solenoid valve and the user terminal to ensure a stable gas supply within a safe pressure range. Pressure regulators with self-diagnostic functions add an automatic detection and diagnostic system to traditional regulators. This system can promptly issue alarms and record fault data when abnormalities occur (such as solenoid valve shut-off or pressure imbalance), providing accurate information to maintenance personnel and reducing the time and manpower costs spent on troubleshooting.

[0003] However, in practical applications, most pressure regulators with fault self-diagnosis functions still have many shortcomings. The fault self-diagnosis of these pressure regulators has low sensitivity to detecting problems such as pressure backflow caused by solenoid valve cut-off. Often, the self-diagnosis system only issues an early warning after the pressure regulator has already experienced a cut-off fault, and cannot capture abnormal signals in time in the early stages of the fault, resulting in gas interruption for users and the need to wait for professional personnel to repair on-site.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

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.

[0026] Example 1:

[0027] like Figures 1-7 As shown, a voltage regulator with a fault self-diagnosis function according to an embodiment of the present invention includes an electromagnetic shut-off valve 1 (a conventional structure not shown in detail). In actual use, the electromagnetic shut-off valve 1 is externally equipped with a protective housing, such as... Figure 1As shown, a pressure regulating box 2 is provided on one side of the electromagnetic shut-off valve 1. The pressure regulating box 2 is usually equipped with a pressure regulator, a filter, a safety protection device (such as a safety relief valve), and a pressure gauge. The specific connection method is the existing conventional technical means, so it will not be described in detail. A pressure regulating component 3 is provided between the pressure regulating box 2 and the electromagnetic shut-off valve 1. Connecting components 4 are provided at both ends of the pressure regulating component 3.

[0028] The pressure regulating assembly 3 includes an output pipe 301 and an input pipe 302 for conveying and outputting gas. The output pipe 301 and the input pipe 302 are respectively connected to the output end of the electromagnetic shut-off valve 1 and the input end of the pressure regulating box 2. A check valve 303 is provided between the output pipe 301 and the input pipe 302 to prevent pressure backflow caused by the electromagnetic shut-off valve 1 being shut off. A self-test cylinder 304 is provided at one end of the check valve 303. The connection between the self-test cylinder 304 and the check valve 303 can be set as welding or flange connection. The specific connection method is determined according to the specific process. It is used to support the flow sensor 305 and the motor 306. The self-test cylinder 304 is configured in two sections, with flow sensors 305 symmetrically arranged on it. The flow sensors 305 serve as the detection end of the ultrasonic flow meter and are connected to a main unit (not shown in detail in the figure) during actual use. The specific connection method with the main unit is a conventional existing technology and will not be described in detail. The flow sensors 305 are electrically connected via an external controller and power supply during actual use. A motor 306 is mounted on the self-test cylinder 304 via a mounting bracket. During actual use, a housing is provided around the motor 306 for protection. The motor 306 is also connected via an external... The controller and power supply are electrically connected. The output shaft of the motor 306 is equipped with a first adjusting gear 307, which meshes with a second adjusting gear 308. The second adjusting gear 308 has protrusions on both sides and is movably connected to one side of the two self-test cylinders 304 via these protrusions. A first adjusting plate 309 is fixedly mounted on the second adjusting gear 308. A second protrusion is located on one side of the first adjusting plate 309, and a second adjusting plate 310 is movably connected to one side of the first adjusting plate 309 via the second protrusion. The second adjusting plate 310 is fixedly located inside the self-test cylinder 304. In actual use, a sealing structure is provided between the first regulating plate 309 and the second regulating plate 310 to avoid leakage. The first regulating plate 309 and the second regulating plate 310 are respectively provided with a first regulating port 311 and a second regulating port 312 at equal distances. The first regulating port 311 and the second regulating port 312 are staggered. That is, when the pressure regulator is in normal state, the overlapping diameter of the first regulating port 311 and the second regulating port 312 can be adjusted according to the flow rate of the flow sensor 305. If the pressure regulator malfunctions, the first regulating port 311 and the second regulating port 312 are not overlapping, that is, they are staggered.

[0029] Example 2:

[0030] like Figures 1-7 As shown, according to an embodiment of the present invention, a voltage regulator with a fault self-checking function includes a connecting component 4 comprising a connector 401. The connector 401 is fixedly disposed at one end of the check valve 303 and the self-checking cylinder 304. A connecting seat 402 is connected to one end of the output pipe 301 and the input pipe 302. The connection between the connector 401, the connecting seat 402 and the output pipe 301 and the input pipe 302 can be configured as a welding or flange connection. The specific connection method is determined according to the specific process. The connecting seat 402 is respectively connected to the output pipe 301 and the input pipe 302. The connector 402 is symmetrically provided with adjustment ports. A mounting base 403 is provided on one side of the adjustment port. A limit handle 404 is movably connected to the mounting base 403 via a rotating shaft to limit the connector 401. One end of the connector 401 is located inside the connector 402. A limit groove 5 is provided on the connector 401, and the limit handle 404 is adapted to the limit groove 5. A sealing ring 6 is provided inside the connector 402. The sealing ring 6 is made of rubber. A limit hole is provided on the mounting base 403, and a fixing bolt 7 is provided inside the limit hole.

[0031] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0032] In summary, with the help of the above-mentioned technical solution of this utility model, when the device is in normal working condition, the gas enters the pressure regulating component 3 from the output end of the electromagnetic shut-off valve 1 through the output pipe 301. The check valve 303 plays the role of preventing pressure backflow caused by the shut-off of the electromagnetic shut-off valve 1. The gas flowing into the pressure regulating component 3 enters the self-test cylinder 304 after passing through the check valve 303. The flow sensor 305 in the self-test cylinder 304 monitors the gas flow in real time. The flow sensor 305 is connected to an external controller and transmits the data to it for analysis and processing.

[0033] If the electromagnetic shut-off valve 1 shuts off due to a malfunction, causing pressure backflow, the check valve 303 first prevents pressure backflow. Simultaneously, the flow sensor 305 inside the self-test cylinder 304 monitors flow changes in real time. When an abnormal flow is detected, the external controller receives the signal and quickly starts the motor 306. The output shaft of the motor 306 drives the first adjusting gear 307 to rotate, and the meshing second adjusting gear 308 rotates accordingly. The second adjusting gear 308 drives the first adjusting plate 309 to move. The first adjusting plate 309 and the second adjusting plate 310 fixed inside the self-test cylinder 304 cooperate through staggered first adjusting ports 311 and second adjusting ports 312, maintaining the current staggered state of the first adjusting ports 311 and second adjusting ports 312, thus limiting the gas flow and effectively controlling pressure backflow to ensure system pressure stability.

[0034] The connecting component 4 serves a sealing and connecting function during the operation of the pressure regulator. The connector 401 mates with the connecting seat 402, and the engagement of the limit handle 404 with the limit groove 5 ensures a stable connection. Simultaneously, the sealing ring 6 inside the connecting seat 402 guarantees a tight seal at the connection point, preventing gas leakage. When maintenance of the pressure regulating component 3 is required, the connector 401 can be removed from the connecting seat 402 by loosening the limit handle 404, allowing for easy disassembly of the pressure regulating component 3 for repair or replacement. After maintenance, the pressure regulating component 3 is reinstalled, with the limit handle 404 engaging with the limit groove 5 to ensure a tight connection.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
