Description

Technical Field

[0001] This invention relates to the field of gas valve technology, and in particular to an intelligent gas flow regulating valve. Background Technology

[0002] As a core component of gas pipeline systems, gas regulating valves are typically used to control the flow rate, pressure, and direction of gas. During long-term use, traditional gas regulating valves are prone to problems such as internal rotation and decreased sealing due to factors such as increased gas flow and pressure generated during gas flow. This not only affects the service life of the regulating valve but also reduces the accuracy of flow regulation and increases the risk of gas leakage. In particular, there are increasingly more safety issues in industrial and household gas systems.

[0003] Traditional control valves mainly rely on a single-layer sealing structure. Under high pressure, high temperature and intermittent gas conditions, their sealing performance is easily affected, making it difficult to maintain a sealing state efficiently for a long time. In particular, after the control valve has been used for a long time, the sealing performance is prone to decline, increasing the possibility of gas emissions. Furthermore, most traditional control valves cannot achieve automatic shut-off function in the event of gas leakage, requiring additional safety equipment or manual operation to close the valve. This design has a slow response speed when a leak occurs. Summary of the Invention

[0004] The purpose of this invention is to improve the sealing performance of the regulating valve and enable automatic and manual control of the opening and closing of the regulating valve.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent gas flow regulating valve, comprising a valve body and a ball valve, wherein the ball valve comprises a primary valve core and a secondary valve core rotatably connected thereto, the primary valve core and the valve body forming upper and lower liquid storage chambers, a gas detector and a liquid level sensor being installed in the liquid storage chambers, a lubricating ring being provided on the outside of the secondary valve core, the valve body being provided with upper and lower rotating rods, and the simultaneous insertion of the two rotating rods can control the rotation of the ball valve, and a liquid delivery device for conveying liquid to the liquid storage chambers is provided on a pipe on one side of the valve body;

[0006] The secondary valve core has an inner chamber and an outer chamber. The secondary valve core has an air supply port that connects to the outer chamber. A baffle is rotatably connected to the outer chamber. The baffle is driven by a gear to an annular plate in the inner chamber. The annular plate is connected to a return spring. The bottom wall of the inner chamber has a rectangular hole.

[0007] The primary valve core has an upper chamber and a lower chamber. A motor is installed in the upper chamber. The motor drives the secondary valve core to rotate through gears. The bottom of the primary valve core has a first infusion port that connects the liquid storage chamber and the lower chamber. The primary valve core also has a second infusion port that connects the rectangular hole and the lower chamber.

[0008] As a further description of the above technical solution: the upper and lower sides of the valve body are fixed with cover plates by bolts, and the cover plates are fitted with limit plates by bolts. Both rotating rods are threaded through the limit plates. The threaded section of the upper rotating rod is longer than the threaded section of the lower rotating rod. The upper and lower sides of the first-stage valve core pass through the valve body and the cover plates. The cover plates are provided with lockers for locking the first-stage valve core.

[0009] As a further description of the above technical solution: the front of the valve body is provided with an observation window for observing the liquid storage cavity, the lubricating ring is fixedly connected to the inner cavity wall of the valve body, and the upper and lower sides of the lubricating ring extend to the liquid storage cavity and block the communication between the upper and lower liquid storage cavities.

[0010] As a further description of the above technical solution: the infusion device includes a storage tank, which is installed on the pipes on both sides of the valve body through a connector. The storage tank is connected to a diversion valve installed on the connector, and the diversion valve is connected to the upper and lower storage chambers through pipes respectively.

[0011] As a further description of the above technical solution: a piston is installed inside the liquid storage tank, and an electric push-pull rod that penetrates the liquid storage tank is fixed to the top of the piston. An inlet pipe is provided at the top of the outer ring of the liquid storage tank.

[0012] As a further description of the above technical solution: the annular plate is rotatably connected to the inner wall of the inner cavity, the return spring is fixedly connected to the inner wall of the inner cavity, and the annular plate and the inner wall of the inner cavity form an injection space.

[0013] As a further description of the above technical solution: the top of the secondary valve core is provided with a protruding plate that extends through the upper chamber, the protruding plate is provided with protruding teeth that mesh with the gear at the output end of the motor, and the motor has a power-off self-locking function.

[0014] As a further description of the above technical solution: the first-stage valve core is provided with a cylindrical space that runs vertically through it, and both rotating rods pass through the cover plate and extend into the cylindrical space.

[0015] As a further description of the above technical solution: a sliding member that can slide up and down is snapped into the cylindrical space, and a plate that works with the sliding member is fixed to the rotating rod below. Several return springs are fixed to the sliding member and the inner wall of the cylindrical space.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0017] 1. The lubricating fluid is delivered to the reservoir via an infusion device, ensuring the ball valve is always lubricated, reducing component wear, and extending the ball valve's service life. When gas leaks from the connection between the valve body and the valve cover, the gas flow passes through the reservoir and comes into contact with the lubricating fluid, generating bubbles. The formation and changes of these bubbles can be monitored through an observation window, allowing for rapid identification of gas leaks. A gas detector can also detect the presence of gas in the reservoir. Simultaneously, a level sensor detects changes in the lubricating fluid level, ensuring timely replenishment of lubricating fluid when the level falls below the set value. This design enhances system reliability and helps prevent malfunctions caused by insufficient lubrication.

[0018] 2. Lubricating fluid is delivered to the lower storage chamber via the infusion device. The lubricating fluid enters the lower chamber through infusion port one, and then enters the inner chamber of the secondary valve core through infusion port two and the rectangular hole. With the continuous injection of lubricating fluid, the annular plate is driven to rotate, which in turn drives the baffle to rotate through gear transmission, thereby achieving the sealing of the gas inlet and more precise adjustment of the gas flow. The lubricating fluid not only extends the service life of the components, but also provides the driving force for the rotation of the baffle, helping the baffle to seal the gas inlet.

[0019] 3. The motor drives the rotation of the secondary valve core, which connects to the pipes on both sides of the valve body through gas inlets of different sizes, thereby achieving graded flow regulation. This system allows for graded flow control to meet diverse needs, improving the accuracy and flexibility of regulation. When a gas leak is detected, the motor will automatically drive the secondary valve core to rotate, causing the gas inlets to close automatically and preventing further leakage. This automated leak-proof function enhances safety and effectively reduces the risk of leakage.

[0020] 4. By rotating the secondary valve core, the air outlet is rotated to the position of the lubrication ring, achieving an external seal. At the same time, the lubricating fluid drives the baffle to rotate inside the secondary valve core, further sealing the air outlet from the inside. The double sealing structure improves the overall sealing performance, preventing external gas from entering or internal gas from leaking, and is suitable for harsh environments such as high temperature and high pressure.

[0021] 5. When the motor malfunctions, the user can manually control the ball valve by inserting two rotating rods and manually supply lubricant. This ensures that the valve can still be smoothly controlled even when the automatic function fails. Furthermore, the ball valve can only be manually rotated when both rotating rods are inserted simultaneously, reducing the possibility of misoperation and avoiding the risk of gas leaks caused by children or others accidentally turning the gas valve, thus further improving the safety of the system.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1-9 The present invention provides an intelligent gas flow regulating valve, including a valve body 10 and a ball valve 20. The valve body 10 is made of a high temperature resistant and corrosion resistant metal material. The cover plate 11 is fixedly connected to the upper and lower sides of the valve body 10 by bolts. This design facilitates the structural stability of the valve body 10, and makes it easy to disassemble and install, maintain and replace internal components, thereby reducing maintenance costs.

[0039] The ball valve 20 includes a primary valve core 21 and a secondary valve core 22 rotatably connected to it. The secondary valve core 22 can rotate around the primary valve core 21. The ball valve 20 is located in the middle part of the inner cavity of the valve body 10 and forms two liquid storage chambers 50 with the valve body 10. The upper and lower sides of the primary valve core 21 penetrate the valve body 10 and the cover plate 11. The primary valve core 21 can rotate in the valve body 10. The liquid storage chamber 50 is filled with lubricating fluid. The lubricating fluid in the liquid storage chamber 50 can ensure that the primary valve core 21 is always in a lubricated state, thereby improving the service life of the primary valve core 21.

[0040] The secondary valve core 22 is provided with a lubricating ring 32. The lubricating ring 32 is fixedly connected to the inner wall of the valve body 10. The upper and lower sides of the lubricating ring 32 extend to the liquid storage chamber 50 and prevent the upper and lower liquid storage chambers 50 from communicating. On the one hand, the lubricating ring 32 ensures that the secondary valve core 22 is always lubricated when rotating, avoiding wear caused by dry friction. On the other hand, the lubricating ring 32 separates the upper and lower liquid storage chambers 50, ensuring that the lubricating fluid exists independently in their respective chambers.

[0041] The liquid storage chamber 50 is equipped with a gas detector 30 and a liquid level sensor 31. The gas detector 30 is used to detect whether there is gas in the liquid storage chamber 50. When gas is detected, an alarm signal is issued to remind the staff that there may be a leak. The liquid level sensor 31 is used to monitor the change of lubricating fluid level in the liquid storage chamber 50 and promptly reminds the staff to replenish the lubricating fluid. The gas detector 30 is encapsulated with a corrosion-resistant alloy or stainless steel shell to meet the requirements of the gas environment. The liquid level sensor 31 is made of high-temperature resistant sensing material to ensure that the accuracy is not affected in the long-term working environment.

[0042] When gas leaks from the connection between valve body 10 and cover plate 11, it passes through the reservoir 50. When the gas comes into contact with the lubricating fluid, it produces bubbles. The observation window 14 is installed on the outer wall of valve body 10, which allows users to observe the state of the lubricating fluid and the presence of bubbles in the reservoir 50. Through the observation window 14, staff can directly monitor whether there are bubbles in the reservoir 50, thereby determining whether there is gas in the reservoir 50. The observation window 14 is made of high-transparency, high-temperature and pressure resistant glass material (such as quartz glass) and is equipped with a high-temperature resistant sealing gasket to ensure that there will be no leakage in a high-pressure gas environment. The setting of the observation window 14 not only facilitates the direct detection of leakage, but also works with the gas detector 30 and the liquid level sensor 31 to form a complete monitoring system, providing a reliable guarantee for the safety of the gas flow regulating valve.

[0043] The secondary valve core 22 has two chambers inside, namely an outer chamber 52 and an inner chamber 51. The outer ring of the secondary valve core 22 has a gas supply hole 221 that connects to the outer chamber 52. The gas supply hole 221 has several different specifications. The outer chamber 52 realizes the flow and flow control of gas through these gas supply holes 221. When the secondary valve core 22 rotates, the gas supply holes 221 of different specifications can be aligned with the pipes on both sides of the valve body 10, allowing gas to flow in from one side of the pipe, pass through the outer chamber 52 and flow out from the other side, so as to realize the flow transmission of gas.

[0044] The gas inlet 221 comes in various specifications to meet different flow requirements. By adjusting the angle of the secondary valve core 22, the gas inlet 221 of a specific size can be aligned with the pipeline, allowing for graded control of the gas flow to adapt to various usage needs. This graded flow regulation method greatly improves the accuracy of flow control. Since the secondary valve core 22 needs to work in a high temperature and high pressure environment for a long time, it is recommended to use high-strength alloy materials that are wear-resistant and corrosion-resistant, such as stainless steel or titanium alloy, to enhance its service life and operational stability.

[0045] The lubricating ring 32 is fixedly installed on the inner wall of the valve body 10. The lubricating ring 32 is in contact with the outside of the secondary valve core 22. When the secondary valve core 22 rotates to a certain position, the lubricating ring 32 covers and seals all the gas delivery holes 221, thereby sealing the gas delivery holes 221 from the outside and completely interrupting the gas flow. This design forms an external sealing protection to ensure that there is no gas leakage in the gas delivery holes 221 when they are not in operation.

[0046] The sealing of the lubricating ring 32 only acts on the outside, while the inner sealing is accomplished by the baffle 222. The baffle 222 is a rotating element in the outer chamber 52, mainly used to close or regulate the flow of the gas outlet 221. When the baffle 222 rotates to completely cover the gas outlet 221, the gas flow is completely blocked. With the adjustment of different angles, the baffle 222 can control the flow of gas through the gas outlet 221 of different specifications, so as to achieve more precise flow control. The baffle 222 is made of high temperature and corrosion resistant ceramic material or nickel alloy to ensure durability and sealing effect in long-term operation.

[0047] The double sealing structure of the outer lubrication ring 32 and the inner baffle 222 provides higher airtightness and effectively prevents gas leakage.

[0048] The annular plate 223 is located inside the inner chamber 51 and is linked to the baffle 222 via gears. It transmits the driving force of the lubricating fluid to the baffle 222, achieving its rotary sealing function. A return spring 224 is connected to the annular plate 223. The annular plate 223 and the inner wall of the inner chamber 51 form an injection space 55. When lubricating fluid enters the injection space 55, it pushes the annular plate 223 to rotate, compressing the return spring 224. When the return spring 224 is fully compressed, the baffle 222 seals all the air outlets 221. Figure 4 As shown; when the lubricant is extracted, the return spring 224 automatically causes the annular plate 223 to return to its initial position.

[0049] A rectangular hole 225 is provided on the bottom wall inside the inner cavity 51. The rectangular hole 225 is connected to the injection space 55. The rectangular hole 225 can continuously inject lubricating fluid into the injection space 55. Under the push of the lubricating fluid, the annular plate 223 drives the baffle 222 to rotate and seal. After the control ends, the return spring 224 restores the initial state.

[0050] The valve body 10 is equipped with a liquid delivery device 40 for delivering liquid to the liquid storage chamber 50. The liquid delivery device 40 has two modes: automatic and manual. The automatic mode is used for normal lubrication supply. When the automatic function of the regulating valve fails, lubricant can also be supplied manually. This design not only improves the reliability of the system, but also ensures that the supply of lubricant is not interrupted in emergency situations. In order to ensure that the liquid delivery device 40 operates stably in high-temperature environments, it should be made of high-temperature and corrosion-resistant materials, such as fluororubber seals combined with stainless steel structures, to maintain sealing effect and durability.

[0051] The primary valve core 21 has two chambers, an upper chamber and a lower chamber. The upper chamber 53 is equipped with a motor 211 that drives the secondary valve core 22. The lower chamber 54 is connected to the lower liquid storage chamber 50 through a liquid inlet 212 to facilitate the flow of lubricating fluid. The motor 211 is powered by a battery in the upper chamber 53.

[0052] The motor 211 drives the rotation of the secondary valve core 22 through gears. The several gas outlets 221 on the secondary valve core 22 rotate to the position of connecting with or closing the pipeline of the valve body 10 under the drive of the motor 211, thereby realizing the rapid switching of the gas flow state. The drive of the motor 211 not only enables the regulating valve to achieve automatic control, but also simplifies the operation steps and improves the response speed of the regulating valve.

[0053] When the infusion device 40 increases the delivery of lubricating fluid to the lower reservoir 50, as the level of the lubricating fluid in the lower reservoir 50 rises, the liquid in the lower reservoir 50 enters the lower chamber 54 through the infusion port 212. The first-stage valve core 21 is provided with an infusion port 213 that connects the rectangular hole 225 and the lower chamber 54. As the level of the lubricating fluid in the lower chamber 54 rises, the lubricating fluid enters the injection space 55 through the infusion port 213 and the rectangular hole 225, thereby controlling the rotation of the baffle 222.

[0054] The valve body 10 is equipped with two rotating rods 33, one above the other. Only by inserting both rotating rods 33 at the same time can the rotation of the ball valve 20 be controlled, thus preventing children from turning the gas valve and reducing the possibility of gas leakage.

[0055] Furthermore, the upper and lower sides of the valve body 10 are fixed with cover plates 11 by bolts, and the cover plates 11 are fitted with limit plates 12 by bolts. Both rotating rods 33 are threaded through the limit plates 12. The threaded section of the upper rotating rod 33 is longer than the threaded section of the lower rotating rod 33. The upper and lower sides of the first-stage valve core 21 pass through the valve body 10 and the cover plates 11. The cover plates 11 are provided with lockers 13 for locking the first-stage valve core 21.

[0056] The locking device 13 is designed as a fixing screw. By inserting the locking device 13 into the reserved hole of the cover plate 11, the first-stage valve core 21 is locked and thus fixed, preventing the rotation of the first-stage valve core 21 in the non-operating state.

[0057] The primary valve core 21 has a cylindrical space 56 that runs vertically through it. Two rotating rods 33 pass through the cover plate 11 and extend into the cylindrical space 56. A sliding member 34 is provided in the cylindrical space 56. The sliding member 34 can slide up and down in the cylindrical space 56. The sliding member 34 is provided with several return springs 36 to provide a return force, ensuring that the sliding member 34 returns to its initial position after the operation is completed, thereby improving the stability of the device and the reliability of repeated use.

[0058] When the automatic function of the regulating valve fails, rotate the upper rotating rod 33 so that it rotates and inserts into the cylindrical space 56. The upper rotating rod 33 contacts the sliding member 34, and the upper rotating rod 33 drives the sliding member 34 to move downward in the cylindrical space 56. At this time, the return spring 2 36 is compressed. While rotating the upper rotating rod 33, rotate the lower rotating rod 33. Since the threaded section of the lower rotating rod 33 is shorter, when the threaded section of the lower rotating rod 33 moves between the limit plate 12 and the cover plate 11, the lower rotating rod 33 can move and rotate freely in the cylindrical space 56. At this time, let the lower rotating rod 33 drive the insert plate 35 to move towards the sliding member 34. Then the insert plate 35 inserts into the sliding member 34, the locking device 13 is removed, and rotating the lower rotating rod 33 can drive the sliding member 34 to rotate, thereby driving the first-stage valve core 21 and the second-stage valve core 22 to rotate simultaneously.

[0059] If only the upper rotating rod 33 is operated, the sliding member 34 cannot move to the insert plate 35. If only the lower rotating rod 33 is operated, the insert plate 35 cannot be inserted into the sliding member 34. If the locking device 13 is not removed, the first-stage valve core 21 cannot rotate, thus preventing children from turning the gas valve and reducing the possibility of gas leakage.

[0060] Furthermore, the reservoir 41 is the main storage unit for the lubricating fluid. It is securely installed on the pipes on both sides of the valve body 10 via the connector 42. This installation method ensures that the lubricating fluid can be quickly delivered to the key positions inside the valve body 10 when the system is operating. Inside the reservoir 41, there is a piston 44. The top of the piston 44 is connected to an electric push-pull rod 45. The electric push-pull rod 45 passes through the top of the reservoir 41, allowing the piston 44 to move up and down inside the reservoir 41, thereby pushing the lubricating fluid in the reservoir 41 into the pipes. This design enables the piston 44 and the electric push-pull rod 45 to work together to achieve precise control of the lubricating fluid.

[0061] Lubricating fluid can be added to the storage tank 41 through the inlet pipe 46. The piston 44 can be moved by the electric push-pull rod 45, allowing the lubricating fluid in the storage tank 41 to enter the diversion valve 43. The diversion valve 43 can control the flow of lubricating fluid to the upper and lower storage chambers 50. The electric push-pull rod 45 can also be pushed and pulled manually.

[0062] The electric push-pull rod 45 not only provides automated operation but also manual operation, ensuring that the lubricant can still be manually pushed in the event of a power system failure. When in use, the electric push-pull rod 45 releases the lubricant quantitatively by pushing or pulling the piston 44 up or down. This dual operation mode ensures continuous operation of the equipment under various working conditions, greatly improving the reliability and applicability of the device.

[0063] Furthermore, the annular plate 223 is rotatably connected to the inner wall of the inner chamber 51, the return spring 224 is fixedly connected to the inner wall of the inner chamber 51, and the secondary valve core 22 is provided with a protruding plate 226 that extends through the upper chamber 53. The protruding plate 226 is provided with protruding teeth 227 that mesh with the gear at the output end of the motor 211. The motor 211 can drive the protruding plate 226 to rotate, thereby driving the secondary valve core 22 to rotate.

[0064] When the regulating valve is working, the locking device 13 locks the first-stage valve core 21. At this time, the motor 211 drives the convex plate 226 to rotate, which in turn drives the second-stage valve core 22 to rotate around the first-stage valve core 21. The air outlet 221 of the second-stage valve core 22 is aligned with the pipes on both sides of the valve body 10. Then, the lubricating fluid is drawn from the lower reservoir 50 through the liquid delivery device 40. Under the action of gravity and the return spring 224, the lubricating fluid in the injection space 55 returns to the lower reservoir 50, thereby controlling the rotation of the baffle 222 and opening the air outlet 221.

[0065] When the regulating valve needs to be closed, the motor 211 drives the convex plate 226 to rotate, which in turn drives the secondary valve core 22 to rotate around the primary valve core 21. This causes the air outlet 221 of the secondary valve core 22 to contact the lubrication ring 32, sealing the air outlet 221 from the outside. Then, the delivery of lubricating fluid to the lower liquid storage chamber 50 is increased, allowing the lubricating fluid to enter the injection space 55. The baffle 222 rotates, sealing the air outlet 221 from the inside.

[0066] When the automatic function of the regulating valve fails, the lubricant can be injected into the lower reservoir 50 by manually operating the electric push-pull rod 45, thereby controlling the baffle 222 to open. At the same time, two rotating rods 33 are inserted to control the rotation of the ball valve 20, ensuring that the opening and closing of the valve can still be smoothly controlled when the automatic function fails.

[0067] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
