Description

Technical Field

[0001] This utility model belongs to the field of valve technology, specifically relating to an intelligent pressure regulating valve. Background Technology

[0002] In related technologies, intelligent pressure regulating valves are commonly used key components in gas supply systems, typically comprising a valve body, a pressure regulating assembly, and an overcurrent shut-off assembly. The valve body has an inlet chamber and an exhaust chamber. The inlet chamber connects to gas storage devices such as gas cylinders, while the exhaust chamber connects to burners such as gas stoves, thus enabling gas delivery. The pressure regulating assembly is located in the inlet chamber and / or exhaust chamber, and its function is to regulate the gas pressure, ensuring that gas is supplied to the burner at a suitable pressure, guaranteeing combustion stability and efficiency. The overcurrent shut-off assembly is located between the inlet and exhaust chambers. When the gas pressure in the inlet chamber is too high, the overcurrent shut-off assembly quickly cuts off the connection between the inlet and exhaust chambers, preventing a large amount of gas from the storage device from continuing to enter the inlet chamber, and preventing safety accidents caused by excessive gas pressure.

[0003] However, existing intelligent pressure regulating valves have significant safety hazards. In emergencies such as gas leaks, the overcurrent cut-off component fails to function, failing to cut off the gas supply from the storage device to the intake chamber, leading to continuous gas leakage and posing a significant risk of fire, explosion, and other serious accidents. Furthermore, current technology lacks remote control functionality, making it impossible to operate the pressure regulating valve promptly and remotely upon detecting a safety hazard. Utility Model Content

[0004] In order to overcome at least one of the defects mentioned above in the prior art, the present invention provides an intelligent pressure regulating valve to solve the problems in the prior art that the gas storage device cannot be cut off from the gas inlet chamber in the event of safety hazards such as gas leakage, and that remote control cannot be achieved, thereby improving the safety and intelligence level of the intelligent pressure regulating valve.

[0005] The technical solution adopted by this utility model to solve its problem is: An intelligent pressure regulating valve includes: a main valve body having an intake chamber and an exhaust chamber; a pressure regulating component movably disposed within the intake chamber and / or exhaust chamber; and a shut-off valve mechanism including a control valve body, a movable component, an electromagnetic component, and a control module. The control valve body has a first channel, a second channel, and a connecting groove. The first channel communicates with the intake chamber, and the second channel communicates with the exhaust chamber. The movable component is movably disposed within the connecting groove, which has a connecting hole. The electromagnetic component is disposed within the control valve body. The control module and the electromagnetic component are electrically connected. The module is used to control the power supply to and from the electromagnetic component; when the movable part is in the first position, a connecting gap is formed between the movable part and the connecting hole, and the connecting gap connects the first channel and the second channel; when the movable part is in the second position, the movable part blocks the connecting hole to cut off the connection between the first channel and the second channel; when the air pressure in the connecting groove is too high, the movable part is pushed by the air pressure to move from the first position to the second position; when the electromagnetic component is energized, the electromagnetic component can drive the movable part to move from the first position to the second position.

[0006] As an optional implementation, the main valve body is provided with a straight plug, which is connected to the air inlet chamber and is used to connect to the air storage device.

[0007] As an optional implementation, the control valve body is detachably connected to the main valve body.

[0008] As an optional implementation, a buffer pad is provided at the connecting hole, and the buffer pad is provided with a vent hole, which is connected to the connecting hole; when the movable member is in the first position, a connecting gap is formed between the movable member and the vent hole; when the movable member is in the second position, the movable member abuts against the buffer pad to eliminate the connecting gap.

[0009] As an optional implementation, the electromagnetic component includes an electromagnet and a push rod; the electromagnet is disposed in the control valve body, and the push rod is at least partially movably disposed in the communicating groove; when the electromagnet is energized, it can magnetically drive the push rod to move to the trigger position, so as to move the movable part from the first position to the second position.

[0010] As an optional implementation, the electromagnetic component further includes a first elastic element disposed on the push rod, and the movable member is located within the first elastic element. The first elastic element is used to guide the displacement of the movable member between the first position and the second position.

[0011] As an optional implementation, the shut-off valve mechanism further includes a guide seat disposed within the communicating groove, and the push rod is slidably connected to the guide seat.

[0012] As an optional implementation, both the first channel and the second channel extend in a first direction, and the connecting groove extends in a second direction, wherein the first direction and the second direction are perpendicular to each other.

[0013] As an optional implementation, the shut-off valve mechanism further includes a pressure rod, which is at least partially movably disposed within the communicating groove; when the pressure rod is pressed, the pressure rod can press against the movable member to reset the movable member from the second position to the first position.

[0014] As an optional implementation, the moving part is a ball bearing.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, the shut-off valve mechanism features dual protection functions: overcurrent shut-off and intelligent shut-off. When the gas pressure in the connecting groove is too high, the moving part will automatically cut off the connection between the first and second channels under the pressure, achieving overcurrent protection. When the electromagnetic component is energized according to the control module's instructions, it can drive the moving part to cut off the channel, achieving intelligent shut-off. This dual protection mechanism can effectively cope with various emergencies, greatly improving the safety of the intelligent pressure regulating valve and reducing the probability of safety accidents. Secondly, the control valve body is set independently of the main valve body.

Thirdly, through the electrical connection between the control module and the electromagnetic component, the energization and de-energization of the electromagnetic component can be controlled according to a preset program or remote control signal, thereby realizing remote operation of the shut-off valve mechanism. When safety hazards such as gas leaks are detected, operators can remotely cut off the gas supply in a timely manner to prevent the accident from escalating, improving emergency response capabilities and intelligent management levels.

[0024] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0025] Please see Figures 1 to 7 This application provides an intelligent pressure regulating valve, which includes a main valve body 1, a pressure regulating component 2, and a shut-off valve mechanism 3; the main valve body 1 has an air inlet chamber 11 and an exhaust chamber 12; the pressure regulating component 2 is movably disposed in the air inlet chamber 11 and / or the exhaust chamber 12, and can control the gas pressure in the air inlet chamber 11 and the exhaust chamber 12 to ensure the stability and safety of the gas supply. The shut-off valve mechanism 3 includes a control valve body 31, a movable part 32, an electromagnetic component 33, and a control module (not labeled in the figure). The control valve body 31 is provided with a first channel 311, a second channel 312, and a connecting groove 313. The first channel 311 can be connected to the air intake chamber 11, and the second channel 312 can be connected to the exhaust chamber 12. The movable part 32 is movably disposed in the connecting groove 313, and a connecting hole 314 is provided in the connecting groove 313. The electromagnetic component 33 is disposed on the control valve body 31, and the control module is electrically connected to the electromagnetic component 33. The control module is used to control the on and off of the electromagnetic component 33. The movable part 32 has two working positions, namely the first position and the second position. When the movable part 32 is in the first position (see reference for details), Figure 4When the moving part 32 is in the second position (see reference 314), a communication gap 35 is formed between the moving part 32 and the communication hole 314. This communication gap 35 connects the first channel 311 and the second channel 312, allowing the gas to flow normally from the intake chamber 11 to the exhaust chamber 12 through the control valve body 31. When the moving part 32 is in the second position (see reference 314 for details), the gas flows through the control valve body 31. Figure 5 When the gas flows through the first channel 311 and the second channel 312, the movable part 32 blocks the connecting hole 314, thereby cutting off the connection between the first channel 311 and the second channel 312 and preventing the gas from continuing to flow. When the air pressure in the connecting groove 313 is too high, the movable part 32 will be pushed by the air pressure and move from the first position to the second position, realizing the overcurrent cut-off function and preventing safety accidents caused by excessive air pressure. When the electromagnetic component 33 is energized, the electromagnetic component 33 can generate electromagnetic force to drive the movable part 32 from the first position to the second position, realizing the intelligent cut-off function. The control module can precisely control the energization and de-energization of the electromagnetic component 33 according to the preset safety program or remote control signal, thereby realizing intelligent control of the cut-off valve mechanism 3.

[0026] It should be noted that when the air pressure in the connecting groove 313 is within a safe range or the safety hazard is eliminated, the movable part 32 can be reset from the second position to the first position under the action of gravity or external force.

[0027] The intelligent pressure regulating valve disclosed in this application has two aspects. First, the shut-off valve mechanism 3 has dual protection functions: overcurrent shut-off and intelligent shut-off. When the air pressure in the connecting groove 313 is too high, the movable part 32 will automatically cut off the connection between the first channel 311 and the second channel 312 under the pressure, thus achieving overcurrent protection. When the electromagnetic component 33 is energized according to the instruction of the control module, it can drive the movable part 32 to cut off the channel, thus achieving intelligent shut-off. This dual protection mechanism can effectively cope with various emergencies, greatly improving the safety of the intelligent pressure regulating valve and reducing the probability of safety accidents. Second, the control valve body 31 is set independently of the main valve body 1. This structural design makes the installation, maintenance and replacement of the shut-off valve mechanism 3 more convenient. At the same time, it is also convenient to optimize and improve the shut-off valve mechanism 3 separately without affecting the normal operation of the main valve body 1, thus improving the reliability and maintainability of the entire intelligent pressure regulating valve. Thirdly, through the electrical connection between the control module and the electromagnetic component 33, the electromagnetic component 33 can be controlled to switch on and off according to a preset program or remote control signal, thereby realizing remote operation of the shut-off valve mechanism 3; when safety hazards such as gas leaks are discovered, operators can remotely cut off the gas supply in a timely manner to avoid the expansion of the accident, thereby improving emergency response capabilities and intelligent management level.

[0028] like Figure 2 and Figure 7As shown, in one embodiment, the main valve body 1 is provided with a straight plug 13, which is connected to the air inlet chamber 11. The straight plug 13 is used to connect to a gas storage device such as a gas cylinder. This design allows users to connect the intelligent pressure regulating valve to the gas cylinder without complicated twisting operations; they only need to insert the straight plug 13 directly into the corresponding interface of the gas cylinder to complete the connection. This greatly simplifies the installation process and saves installation time. Especially for ordinary users who lack professional installation skills or experience, it greatly reduces the installation difficulty and improves installation efficiency.

[0029] like Figure 7 As shown, in one embodiment, the pressure regulating assembly 2 includes a valve stem 21 and a pressure regulating diaphragm 22. The valve stem 21 is rotatably disposed in the exhaust chamber 12, and the pressure regulating diaphragm 22 is movably disposed in the exhaust chamber 12. The valve stem 21 and the pressure regulating diaphragm 22 are connected by transmission. The valve stem 21 drives the pressure regulating diaphragm 22 to control the air pressure in the exhaust chamber 12. In addition, the technology known to those skilled in the art will not be described in detail here.

[0030] like Figure 1 , Figure 3 and Figure 6 As shown, in one embodiment, the control valve body 31 is detachably connected to the main valve body 1. Thus, firstly, the detachable connection allows maintenance personnel to quickly separate the control valve body 31 from the main valve body 1, facilitating detailed inspection and precise repair of the faulty component; compared to non-detachable or difficult-to-disassemble connections, it eliminates the need for extensive time spent on complex disassembly operations, significantly shortening maintenance time, improving equipment maintenance efficiency, reducing downtime due to equipment failure, and ensuring production continuity. Secondly, with the continuous advancement of technology, the performance and functions of the control valve body 31 may be improved. Since the control valve body 31 is detachably connected to the main valve body 1, when a more advanced control valve body 31 technology emerges, the old control valve body 31 can be easily disassembled and replaced with a control valve body 31 with new functions and high performance, without the need for large-scale modification of the main valve body 1. This allows the valve to keep up with the pace of technological development and meet ever-changing usage requirements. Furthermore, the control requirements for the valve may vary in different working scenarios. Through the detachably connected control valve body 31, different types or specifications of control valve bodies 31 can be flexibly replaced according to specific working conditions.

[0031] like Figure 1 , Figure 3 and Figure 6 As shown, in one embodiment, the control valve body 31 and the main valve body 1 are detachably connected by screws 5.

[0032] It should be noted that in some other embodiments, the control valve body 31 and the main valve body 1 can also be detachably connected by, but not limited to, pins or snap-fit ​​structures, depending on actual needs, and are not limited to here.

[0033] like Figure 3 , Figure 4 and Figure 5 As shown, in one embodiment, a buffer pad 34 is provided at the connecting hole 314, and the buffer pad 34 is provided with a vent hole 341, which is connected to the connecting hole 314. When the movable member 32 is in the first position, a connecting gap 35 is formed between the movable member 32 and the vent hole 341. When the movable member 32 is in the second position, the movable member 32 abuts against the buffer pad 34 to eliminate the connecting gap 35. Thus, when the movable member 32 is in the second position and abuts against the buffer pad 34, the buffer pad 34 undergoes elastic deformation, which can tightly fit the surface of the movable member 32, eliminate the connecting gap 35, and form a good sealing effect. Furthermore, when the movable member 32 contacts the buffer pad 34 during movement, the soft material of the buffer pad 34 can reduce the direct collision and friction between the movable member 32 and other hard parts, reducing the degree of wear. This not only extends the service life of the movable member 32 and the buffer pad 34, but also reduces the contamination of the fluid system by impurities caused by wear, improving the cleanliness and reliability of the system. Furthermore, the buffer pad 34 and moving parts 32 are typically designed to be removable, allowing them to be easily removed from the system for inspection, cleaning, or replacement when maintenance or replacement is required. This design simplifies maintenance operations, reduces maintenance time and costs, and improves the maintainability of the system.

[0034] like Figure 3 , Figure 4 and Figure 5 As shown, in one embodiment, the electromagnetic component 33 includes an electromagnet 331 and a push rod 332. The electromagnet 331 is disposed on the control valve body 31, and the push rod 332 is at least partially movably disposed within the connecting groove 313. When the electromagnet 331 is energized, it can magnetically drive the push rod 332 to move to the trigger position, thereby moving the movable part 32 from the first position to the second position. Thus, by disposing the electromagnet 331 on the control valve body 31 and partially movably disposing the push rod 332 within the connecting groove 313, this integrated design makes the structure of the entire electromagnetic component 33 very compact, with a reasonable layout between the various components, reducing unnecessary space occupation. Furthermore, when the electromagnet 331 is energized, it can instantly generate a strong magnetic field, using magnetic force to quickly drive the push rod 332 to move without the delay of intermediate transmission links, enabling the push rod 332 to reach the trigger position in a very short time, thereby quickly moving the movable part 32 from the first position to the second position.

[0035] like Figure 3 , Figure 4 and Figure 5 As shown, in one embodiment, the electromagnetic component 33 further includes a first elastic element 333, which is disposed on the push rod 332, and the movable element 32 is located within the first elastic element 333. The first elastic element 333 is used to guide the displacement of the movable element 32 between the first position and the second position, so that the movable element 32 reduces offset and sway during movement, thereby enabling the movable element 32 to reach the first position and the second position accurately and stably.

[0036] like Figure 3 , Figure 4 and Figure 5 As shown, in one embodiment, the shut-off valve mechanism 3 further includes a guide seat 36, which is disposed within the communicating groove 313, and the push rod 332 is slidably connected to the guide seat 36. Thus, the guide seat 36 provides a clear linear motion track for the push rod 332. When the electromagnet 331 is energized to drive the push rod 332 to move, or when the first elastic element 333 forces the push rod 332 to reset, the push rod 332 can only slide along the linear direction set by the guide seat 36. This effectively avoids skewness or deviation of the push rod 332 during movement, ensuring that the push rod 332 can accurately reach the trigger position and the initial position, thereby enabling the movable element 32 to precisely switch between the first and second positions, achieving precise control of the gas passage shut-off and restoration, and greatly improving the operating accuracy of the shut-off valve mechanism 3.

[0037] like Figure 3 , Figure 4 and Figure 5 As shown, in one embodiment, both the first channel 311 and the second channel 312 extend in a first direction, and the connecting groove 313 extends in a second direction, with the first and second directions perpendicular to each other. Thus, when the movable member 32 switches between the first and second positions, it can more precisely control the connection and disconnection between the first channel 311 and the second channel 312. Because the channels intersect perpendicularly, the movable member 32 only needs to move in the vertical direction to effectively close or open the channels, achieving precise control of fluid flow. Furthermore, the perpendicular channel layout results in a short movement path and low resistance for the movable member 32. When the electromagnet 331 is energized or de-energized, the first elastic member 333 can quickly drive the movable member 32 to move in the vertical direction, achieving rapid disconnection or restoration of the channel. This rapid response capability can improve the operating efficiency of the shut-off valve mechanism 3.

[0038] like Figure 3 , Figure 4 and Figure 5As shown, in one embodiment, the shut-off valve mechanism 3 further includes a pressure rod 37, which is at least partially movably disposed within the communicating groove 313. When the pressure rod 37 is pressed, it presses against the movable member 32 to reset the movable member 32 from the second position to the first position. Thus, the operator can directly press the pressure rod 37 to quickly reset the movable member 32 to the first position, restoring the communication state of the channel. This manual operation method requires no complex tools or cumbersome steps, enabling rapid response in emergencies and timely restoration of normal system operation, greatly improving operational efficiency and convenience.

[0039] like Figure 3 , Figure 4 and Figure 5 As shown, in one embodiment, the shut-off valve mechanism 3 further includes a second elastic element 38, which is sleeved on the pressure rod 37. After the force applied to the pressure rod 37 is released, the second elastic element 38 can elastically drive the pressure rod 37 away from the movable part 32. Thus, firstly, when the operator presses the pressure rod 37 to reset the movable part 32, there is no need to manually pull the pressure rod 37 back to its original position; the second elastic element 38 automatically uses its elastic force to drive the pressure rod 37 away from the movable part 32, restoring it to its initial state. This process is completed automatically, greatly simplifying the operation process and saving operation time and effort. Secondly, the second elastic element 38 keeps the pressure rod 37 in a position away from the movable part 32 when not in operation, avoiding continuous friction caused by accidental contact between the pressure rod 37 and the movable part 32. This design reduces wear on the surfaces of the pressure rod 37 and the movable part 32, extends the service life of the components, reduces the failure rate caused by component wear, and improves the overall stability and reliability of the shut-off valve mechanism 3. Thirdly, the second elastic element 38 provides uniform resistance feedback during the pressing and rebounding of the pressure rod 37. When pressed, the elastic element is gradually compressed, generating stable resistance, allowing the operator to feel a clear change in pressing force, thus avoiding damage to the mechanism due to excessive force. After the force is released, the elastic element smoothly springs the pressure rod 37 back. The entire process is free from obvious jamming or impact, providing the operator with a comfortable and smooth operating feel and improving the operating experience.

[0040] like Figure 3 , Figure 4 and Figure 5As shown, in one embodiment, a sealing ring 39 is fitted onto the pressure rod 37, and the sealing ring 39 makes sealing contact with the wall of the connecting groove 313. Thus, the sealing ring 39 effectively prevents fluid in the connecting groove 313 from leaking out through the gap between the pressure rod 37 and the groove wall. Furthermore, the sealing ring 39 also prevents external impurities, such as dust and moisture, from entering the connecting groove 313. If these impurities enter the shut-off valve mechanism 3, they may clog the channel, wear down the moving parts 32 and the pressure rod 37, etc., affecting the normal operation of the shut-off valve mechanism 3. The sealing effect of the sealing ring 39 effectively isolates external impurities, keeps the connecting groove 313 clean, and provides a good environment for the stable operation of the shut-off valve mechanism 3.

[0041] In one embodiment, the pressure rod 37 is provided with a groove (not labeled in the figure), and the sealing ring 39 is fitted into the groove. Thus, the groove provides a precise installation position for the sealing ring 39, allowing it to be securely fitted onto the pressure rod 37. During the reciprocating motion of the pressure rod 37, the sealing ring 39 will not shift or fall off due to fluid pressure, friction, or vibration, and will always remain in the correct sealing position, thereby ensuring tight contact between the sealing ring 39 and the wall of the connecting groove 313, effectively preventing fluid leakage.

[0042] like Figure 3 , Figure 4 and Figure 5 As shown, in one embodiment, the moving part 32 is a ball. Thus, when the ball is the moving part 32, it primarily experiences rolling friction during movement. The coefficient of rolling friction is much smaller than that of sliding friction, which allows the ball to move more easily when subjected to external forces, greatly reducing resistance during movement.

[0043] It should be noted that in some other embodiments, the movable part 32 may also be, but is not limited to, a movable rib or a movable platform, etc., which can be selected according to actual needs, and is not limited here.

[0044] like Figure 1 and Figure 2 As shown, in one embodiment, the intelligent pressure regulating valve further includes an exhaust pipe 4, which is connected to the exhaust chamber 12 and is used to connect to the burner's piping.

[0045] In summary, the intelligent pressure regulating valve disclosed in this utility model can bring at least the following beneficial technical effects: (1) The shut-off valve mechanism 3 has dual protection functions: overcurrent shut-off and intelligent shut-off. Overcurrent shut-off can automatically cut off the channel when the air pressure in the connecting groove 313 is too high, preventing safety accidents caused by excessive air pressure; intelligent shut-off is achieved by the control module controlling the electromagnetic component 33 to be energized according to a preset program or remote signal, driving the movable component 32 to cut off the channel. The dual mechanism effectively responds to various emergencies and greatly reduces the probability of safety accidents.

[0046] (2) The control valve body 31 is set independently of the main valve body 1. This structural design makes the installation, maintenance and replacement of the shut-off valve mechanism 3 more convenient. At the same time, it is easy to optimize and improve the shut-off valve mechanism 3 separately without affecting the normal operation of the main valve body 1, thereby improving the reliability and maintainability of the entire intelligent pressure regulating valve.

[0047] (3) Through the electrical connection between the control module and the electromagnetic component 33, the power supply of the electromagnetic component 33 can be precisely controlled according to the preset program or remote control signal, thereby realizing the remote operation of the shut-off valve mechanism 3. When safety hazards such as gas leaks are discovered, the operator can remotely shut off the gas supply in a timely manner to avoid the accident from escalating, thereby improving the emergency response capability and the level of intelligent management.

[0048] (4) When the gas pressure in the connecting groove 313 is within a safe range or the safety hazard is eliminated, the movable part 32 can be reset from the second position to the first position under the action of gravity or external force, so that the gas can pass through the control valve body 31 normally, ensuring the convenience of use.

[0049] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
