Description

Technical Field

[0001] This invention relates to the field of gas pressure regulating equipment technology, and more specifically to an intelligent pressure regulating and shut-off valve with a magnetically assisted pressure regulating structure. Background Technology

[0002] Pressure regulators are core control components in the gas transmission and usage process, used to stably adjust high-pressure gas sources to suitable working pressures. Traditional pressure regulators generally adopt a purely mechanical spring-type pressure regulating structure, which changes the preload of the pressure-stabilizing spring on the diaphragm by rotating the pressure-regulating nut, thereby controlling the valve opening to achieve pressure regulation.

[0003] The existing technology has the following shortcomings: The pressure regulation process relies entirely on the spring force. With long-term use, the spring is prone to fatigue and elasticity decay, resulting in unstable pressure output and poor regulation accuracy. The compensation capability is weak under low-pressure conditions, and pressure fluctuations and insufficient gas supply are prone to occur. Lacking intelligent control and safety shut-off functions, it cannot automatically shut off the gas supply in the event of abnormalities such as overpressure or leakage, posing a significant safety hazard. It cannot be linked with alarm devices and smart terminals, making it difficult to achieve remote monitoring and intelligent management.

[0004] To address the aforementioned shortcomings, developing a voltage regulator that offers stable voltage regulation, rapid response, magnetic auxiliary compensation, and intelligent safety shut-off has become an urgent problem to be solved in this field. Summary of the Invention

[0005] To address the aforementioned problems in existing technologies, this invention provides an intelligent pressure regulating and shut-off valve with a magnetically assisted pressure regulating structure.

[0009] Furthermore, a copper connector is connected to the air inlet of the valve body, and an automatic shut-off mechanism is provided on the valve body. The automatic shut-off mechanism includes a rubber component disposed on the air inlet, with a vent hole in the middle of the rubber component. A spherical bead and an automatic slider are sequentially disposed on one side of the rubber component. The automatic slider can move back and forth within the air source channel. When driven, the automatic slider causes the spherical bead to press against the rubber component, thereby blocking or opening the vent hole, realizing the shut-off or opening of the air source channel. A small magnet is installed on the automatic slider. A coil frame is disposed on the outside of the copper connector, and a coil is wound on the coil frame. A coil housing is provided on the outer edge of the coil frame; a magnet chamber is provided between the coil frame and the copper connector, and a magnet ring is installed in the magnet chamber. The magnet ring can move back and forth in the magnet chamber; when the coil is energized, it drives the magnet ring to move, and the magnet ring drives a small magnet and an automatic slider to move. The automatic slider pushes a spherical bead to press against a rubber part to close the vent hole; when a reverse current is applied, it can drive the magnet ring to move in the opposite direction, causing the automatic slider to return to its original position; a manual pull ring is movably provided on the copper connector. The outer ring of the manual pull ring is locked on the coil housing, and a pull ring spring is provided inside the manual pull ring. Pushing the manual pull ring can reset the magnet ring.

[0010] Furthermore, the coil shell is formed by a casting process, which tightly integrates it with the coil frame and the coil wound on it to form a structurally stable integrated component; a positioning groove is provided at the connection between the inner end of the coil shell and the valve body, and a positioning boss that cooperates with the positioning groove is provided at the outer end of the valve body; a waterproof inner groove is provided at the outer end of the valve body.

[0012] Furthermore, a PCB circuit board is provided inside the battery holder, and a battery is installed on the PCB circuit board. The automatic cutting mechanism is electrically connected to the PCB circuit board.

[0013] Furthermore, a conduit is provided on the valve body for running a power cord.

[0014] Furthermore, a battery cover is installed on the battery holder, the outer circumference of the battery cover is provided with anti-slip strips, and an installation slot is provided at the connection between the battery cover and the battery holder.

[0015] Furthermore, the PCB circuit board is wirelessly connected to the combustible gas alarm, and the combustible gas alarm is communicatively connected to a mobile phone or PC.

[0016] The present invention has the following beneficial effects: 1. Smooth and Precise Pressure Adjustment: This invention innovatively introduces a magnetic-assisted pressure adjustment structure. By setting up magnetic block one and magnetic block two, the magnetic attraction characteristic is used to assist or even partially replace the traditional pure spring pressure adjustment. Specifically, the magnetic force is used to balance the elastic force of the pressure-stabilizing spring, resulting in a smooth elastic force. By adjusting the pressure-adjusting nut to change the vertical position of magnetic block one, the magnitude of the attraction between magnetic block one and magnetic block two can be adjusted, thereby precisely fine-tuning the effective force of the pressure-stabilizing spring. The closer magnetic block one is to magnetic block two, the greater the attraction, causing the connecting rod to tilt downwards, increasing the sealing seat clamping force and reducing the output pressure; conversely, the output pressure increases. Through the combined and synergistic pressure adjustment method of magnetic attraction and spring force, the pressure adjustment process becomes more linear and precise.

[0017] 2. Strong low-pressure compensation capability: When the air pressure entering the intake valve is too low, the magnetic block three set on the valve body will generate a downward attraction on the metal hanging rod screw, which will help pull the connecting rod upward, increasing the opening range of the sealing seat, thereby quickly replenishing the output pressure. This effectively solves the problem of insufficient air supply when the traditional pressure regulator is low-pressure intake, ensuring the normal combustion of the downstream combustion appliances.

[0018] 3. High level of intelligence and reliable safety: Built-in sensors monitor the air pressure within the air chamber in real time and integrate an automatic shut-off mechanism. This mechanism combines electromagnetic drive (coil energizing a magnetic ring) and manual reset (manual pull ring). When abnormal air pressure is detected or an external alarm signal is received, the PCB circuit board energizes the coil, quickly driving the automatic slider to close the air path, achieving intelligent and safe shut-off. Simultaneously, a manual reset button provides a means of operation in emergencies or after maintenance.

[0019] 4. IoT Functionality: The PCB circuit board can wirelessly connect to a combustible gas alarm and forward the alarm signal to the user's mobile phone or PC for remote real-time monitoring. In the event of a gas leak or abnormal gas pressure, the user can be notified immediately and can trigger the pressure regulator to automatically cut off the gas supply via a remote signal, greatly improving gas safety.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] See Figures 1 to 3The present invention discloses an intelligent pressure regulating and shut-off valve with a magnetic suction-assisted pressure regulating structure, comprising a valve body 1; the valve body 1 is provided with an air inlet 2 and an air outlet 3, the air outlet 3 being provided with an internal thread for connecting a hoist nozzle; a battery holder 4 is installed at the upper end of the valve body 1, and a pressure regulating lower cover 5 is installed at the lower end of the valve body 1. A diaphragm 6 is provided at the connection between the pressure regulating lower cover 5 and the valve body 1, a pressure regulating nut 7 is provided at the middle of the lower end of the pressure regulating lower cover 5, and a pressure stabilizing spring 8 is provided between the pressure regulating nut 7 and the diaphragm 6.

[0023] An air inlet valve 9 is provided inside the valve body 1. The air source entering through the air inlet 2 enters the air chamber 10 formed by the valve body 1 and the diaphragm 6 through the air inlet valve 9. A pressure regulating mechanism for adjusting the airflow is provided on one side of the air inlet valve 9 inside the valve body 1.

[0024] The pressure regulating mechanism includes a connecting rod 11 hinged to one side of the intake valve port 9, which is rotatably connected to the valve seat via a lever pin 12. A sealing seat 13 is provided at one end of the connecting rod 11, which can open or close the intake valve port 9. A metal hanger screw 14 is connected to the other end of the connecting rod 11, and the metal hanger screw 14 is fixed to the diaphragm 6 via a metal hanger nut 15. To introduce magnetic assistance, a magnetic block 16 is provided at the middle of the upper end of the pressure regulating nut 7, and a magnetic block 27 is provided at the lower end of the metal hanger nut 15. Preferably, the distance between magnetic block 16 and magnetic block 217 is within 15mm. The relative position of magnetic block 16 and magnetic block 217 can change with the rotation of the pressure regulating nut 7, thereby changing the magnetic attraction between them. This magnetic attraction, together with the elastic force of the pressure stabilizing spring 8, acts on the diaphragm assembly to achieve pressure regulation. During adjustment, rotating the pressure regulating nut 7 causes magnetic block 16 to move up and down. The closer magnetic block 16 is to magnetic block 2 17, the stronger the attraction. The downward tilt of connecting rod 11 increases the clamping force of sealing seat 13 and reduces the output pressure; conversely, the output pressure increases.

[0025] To further enhance low-pressure compensation capability, a magnet seat 18 is provided on the valve body 1 at the position corresponding to the metal hanger screw 14. A magnetic block 3 19 is installed inside the magnet seat 18, with the surface of the magnetic block 3 19 and the bottom end of the metal hanger screw within 12mm. When the air pressure entering the inlet valve 9 is low, the position of the diaphragm 6 changes, causing the metal hanger screw 14 to approach the magnetic block 3 19. The magnetic block 3 19 pulls the metal hanger screw 14 downwards, assisting in pulling the connecting rod 11 upwards, opening the sealing seat 13 and rapidly increasing the low-pressure output pressure. The outer end of the magnet seat 18 is provided with a locking platform for holding the magnetic block 3 19, and a vent groove is provided on the side to ensure smooth operation of the magnetic block 3 19 and prevent it from falling off.

[0026] This pressure regulator integrates intelligent monitoring and shut-off functions. A low-pressure sensor 20 is installed on the valve body 1 to monitor the air pressure within the air chamber 10 (i.e., the pressure-regulated rubber diaphragm cavity at the rear end of the regulator's inlet valve 9). A high-pressure sensor 201 is installed on the valve body 1 at the position corresponding to the inlet valve 9 (i.e., the air passage at the front end of the regulator's inlet valve 9, before high-pressure regulation) to measure the high-pressure input pressure. The low-pressure sensor 20 and the high-pressure sensor 201 can be installed simultaneously, or only one can be installed. A copper connector 21 is connected to the air inlet 2, and an automatic shut-off mechanism is provided. This mechanism includes a rubber component 22 installed on the air inlet 2, with a vent 23 in the middle of the rubber component 22. A spherical bead 24 and an automatic slider 25 are sequentially arranged on one side of the rubber component 22. A small magnet 26 is installed on the automatic slider 25. A coil frame 27 and a wound coil 28 are arranged on the outside of the copper connector 21, and an outer coil shell 29 is provided. A magnet chamber 30 is formed between the coil frame 27 and the copper connector 21, which contains a movable magnet ring 31.

[0027] When sensor 20 detects abnormal air pressure (overpressure, underpressure) or receives an external alarm signal, the PCB circuit board 35 inside the battery holder 4 energizes the control coil 28 and generates a magnetic field, driving the magnetic ring 31 to move. The magnetic ring 31 magnetically attracts the small magnet 26 on the automatic slider 25, causing the automatic slider 25 to move synchronously. The automatic slider 25 pushes the spherical bead 24 to press against the rubber part 22 and seal the vent 23, achieving rapid cutoff of the air passage.

[0028] After troubleshooting, a reverse current can be supplied to coil 28 to automatically reset magnet ring 31; alternatively, the manual pull ring 32 on copper connector 21 can be manually pulled to manually reset magnet ring 31 using the force of pull ring spring 33. At this time, spherical bead 24 will still be pressed against the hole of rubber part 22 under air pressure. To restore airflow, press reset button 34 on valve body 1, and push rod 342 to forcibly open closed spherical bead 24, completing manual valve opening for airflow.

[0029] In addition, the spherical bead 24 has an automatic overflow valve shut-off function. When the internal high-pressure airflow velocity exceeds 110% of the set flow rate, the airflow at the hole of the rubber part 22 accelerates and forms a suction force, adsorbing the spherical bead 24 onto the hole of the rubber part 22, thereby quickly cutting off the air source; when restoring air supply, the reset button 34 on the valve body 1 can be pressed, and the spherical bead 24 can be pushed open by the push rod 342 to complete the manual valve opening and air supply.

[0030] The coil housing 29 is formed by a casting process and is tightly integrated with the coil frame 27 and the coil 28 wound on it to form a structurally stable integrated component; the inner end of the coil housing 29 is provided with a positioning groove 291 at the connection between it and the valve body 1, and the outer end of the valve body 1 is provided with a positioning boss 292 that cooperates with the positioning groove 291; the outer end of the valve body 1 is provided with a waterproof inner groove 39.

[0031] In terms of electrical and communication aspects, the battery holder 4 houses a PCB circuit board 35 and a battery 36, providing power to the sensor 20 and the automatic shut-off mechanism. A conduit 37 on the valve body 1 protects the power cord. The PCB circuit board 35 can wirelessly connect to a combustible gas alarm in the user's home. When the alarm detects a gas leak, it simultaneously triggers a local alarm and sends a signal to the pressure regulator, activating the automatic shut-off mechanism to shut off the gas supply. Simultaneously, the PCB circuit board 35 can wirelessly upload alarm information and gas pressure data to the user's mobile app or the property management PC for remote monitoring.

[0032] Working principle of this invention: During pressure adjustment, rotating the pressure adjusting nut 7 causes the magnetic block 16 to move up and down, changing the magnetic attraction between the magnetic block 16 and the magnetic block 17, which helps to offset part of the spring force of the pressure stabilizing spring 8, thus achieving smooth adjustment of the spring force. The closer the magnetic block 16 is to the magnetic block 17, the greater the attraction force. The connecting rod 11 tilts down, causing the sealing seat 13 to press up, reducing the air intake and lowering the output pressure. Conversely, the attraction force decreases and the output pressure increases.

[0033] When the intake pressure is too low, the magnetic block 19 generates a downward suction force on the metal rod screw (14), which drives the connecting rod 11 to tilt upward and the opening of the sealing seat 13 to increase the output pressure and realize low pressure automatic compensation.

[0034] The air pressure inside the air chamber 10 is monitored in real time by the sensor 20. When an abnormality occurs, the PCB circuit board 35 controls the automatic cut-off mechanism to operate. The coil 28 is energized to drive the magnetic ring 31 to move. Through magnetic attraction, the automatic slider 25 and the spherical bead 24 close the vent 23, thereby automatically shutting off the air source. The air supply can be restored by manually pulling the ring 32 or by using the reset button 34.

[0035] The PCB circuit board 35 is linked with the combustible gas alarm to realize leakage alarm and remote monitoring.
