Description

Technical Field

[0001] This invention designs a high-pressure gas controller, specifically a high-pressure gas high-flow-rate rapid filling interface controller and method. Background Technology

[0002] In the field of high-pressure gas control, especially in high-pressure (typically in the range of 20-100 MPa) refueling applications such as compressed natural gas (CNG) and high-pressure hydrogen, traditional two-position three-way valves generally face numerous challenges. These traditional valve designs often cannot effectively adapt to high-pressure conditions and have many drawbacks. Among the more prominent problems are excessive frictional resistance of the control valve core and the tendency for the valve core to jam. These issues not only affect the stability and reliability of the valve but also increase operational difficulty and maintenance costs.

[0003] To address the aforementioned issues, utility model patent CN212273133U proposes a plunger-type rack and pinion driven two-position three-way valve. This patented solution, through innovative design, overcomes, to some extent, the shortcomings of traditional two-position three-way valves under high-pressure conditions, improving the valve's adaptability and reliability.

[0004] However, despite the technological breakthroughs in the utility model patent solution CN212273133U, some problems have still emerged in practical applications. Specifically, the valve core movement in this solution mainly relies on manual control. During the injection of high-pressure, high-flow-rate gas, operators need to apply considerable force to complete operations such as valve core movement, which not only increases the labor intensity of operators but may also affect the convenience and safety of operation. Furthermore, the handle in the aforementioned utility model patent is radially fixed and cannot be rotated. During control, if the handle space is limited and cannot be rotated, operation becomes inconvenient. Summary of the Invention

The ventilation phase involves moving the main valve core assembly and the movable valve core assembly to allow the air source to enter the receiving device from the controller. The present invention has the following advantages: This invention is used to control high-pressure, high-flow-rate gas. By reasonably improving the valve core, a pilot flow channel is used to assist the movement of the valve core by means of the pressure difference at both ends of the valve core, thereby achieving safe and reliable control of high-pressure, high-flow-rate gas. After the valve core is improved, it is easier for operators to control high-pressure, high-flow-rate gas, and its use is also safer and more controllable.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0020] In the field of high-pressure gas control, especially in high-pressure (typically in the range of 20-100 MPa) refueling applications such as compressed natural gas (CNG) and high-pressure hydrogen, traditional two-position three-way valves generally face numerous challenges. These traditional valve designs often cannot effectively adapt to high-pressure conditions and have many drawbacks. Among the more prominent problems are excessive frictional resistance of the control valve core and the tendency for the valve core to jam. These issues not only affect the stability and reliability of the valve but also increase operational difficulty and maintenance costs.

[0021] To address the aforementioned issues, utility model patent CN212273133U proposes a plunger-type rack and pinion driven two-position three-way valve. This patented solution, through innovative design, overcomes, to some extent, the shortcomings of traditional two-position three-way valves under high-pressure conditions, improving the valve's adaptability and reliability.

[0022] However, despite the technological breakthroughs in the utility model patent solution CN212273133U, some problems have still emerged in practical applications. Specifically, the valve core movement in this solution mainly relies on manual control. During the injection of high-pressure, high-flow-rate gas, operators need to apply considerable force to complete gas control and other operations, which not only increases the labor intensity of the operators but may also affect the convenience and safety of operation. Furthermore, the handle in the aforementioned utility model patent is radially fixed and cannot be rotated. If the handle is confined by space during control, operation becomes inconvenient.

[0023] For the reasons mentioned above, such as Figures 1-14 As shown, this embodiment provides a high-pressure gas high-flow-rate fast filling interface controller, including an inlet interface pipe 24, a main valve core assembly 28, a movable valve core assembly, a flow guide shroud 22, an exhaust assembly, a drive assembly, and a filling connection assembly. A main sealing seat 15 is installed inside the interface pipe 23, and the main valve core assembly 28 passes through the main sealing seat 15. The main valve core assembly and the movable valve core assembly are installed in the air inlet pipe 24. The main valve core assembly has a valve core main channel 101 and a gas channel 102. After the high-pressure gas is diverted through the airflow inlet pipe 24, it enters the valve core main channel 101 through the airflow channel 102. The movable valve core assembly is movably fitted onto one end of the main valve core assembly 28 and located inside the air inlet pipe 24. A main valve sealing gasket 16 is installed on the movable valve core assembly. The flow rate of the gas passage 102 is controlled by the degree of contact between the main valve sealing gasket 16 and the main sealing seat 15. The movable valve core assembly has a pilot flow channel, which guides the pilot gas to flow away from the main sealing seat and then merges into the main flow channel of the valve core. The pilot gas is a portion of the gas that is diverted from the inlet pipe to the main valve core assembly.

[0024] The air intake cover 22 is installed inside the air intake interface pipe 24, and the movable valve core assembly is movably installed inside the air intake cover 22. A valve core reset power component 23 (optionally a reset spring) is installed between the inner end of the air intake cover 22 and the end face of the movable valve core assembly.

[0025] The movable valve core assembly includes a movable valve core seat 17 and a movable valve core cover 21, and the main valve sealing gasket 16 is installed at the end of the movable valve core seat 17; The movable valve core seat 17 has a valve core cavity with a central hole. The front part of the movable valve core cover 21 is connected to the valve core cavity. The connection part between the movable valve core cover 21 and the movable valve core seat 17 has a pilot groove 103 that is independent of the valve core cavity (the pilot groove can be formed by a rectangular through groove 211 opened on the movable valve core cover). The air inlet end of the pilot groove is a small gap annular hole 104 formed between the movable valve core seat and the flow guide. A drain hole 105 is provided between the pilot groove 103 and the valve core cavity to connect the pilot groove and the valve core cavity; One end of the main valve core assembly passes through the valve core cavity and extends to the movable valve core cover; The small gap annular hole 104, the pilot groove 103, and the flow guide hole 105 constitute the pilot flow channel.

[0026] Furthermore, the drainage hole 105 is opened in the drainage spacer 19, the drainage spacer 19 is installed in the valve core cavity and is fixed by the pressure of the movable valve core cover. Energy storage sealing rings (energy storage sealing ring B16 and energy storage sealing ring C20) are provided at both ends of the drainage spacer for sealing with the contact surface of the main valve movable valve core seat and the main valve movable valve core cover.

[0027] The exhaust assembly includes an exhaust seat 13, an exhaust valve, and an exhaust pipe 25; The exhaust seat 13 is installed on the main valve core assembly 28 and has an exhaust channel 106 inside the exhaust seat. When the main valve core assembly moves to a designated position, the main valve core channel of the main valve core assembly is connected to the exhaust channel. The exhaust pipe is installed on the exhaust seat via an exhaust valve and is connected to the exhaust passage (e.g., ...). Figure 4 and Figure 5 (As shown).

[0028] The drive assembly acts on the main valve core assembly 28, such as Figure 1 , Figure 2 and Figures 10-14 As shown, the drive assembly includes an intermediate connecting pipe 7, a gearbox 9, a rack ring 8, and a lever 10; The intermediate connecting pipe 7 is connected to the air intake port pipe 24, and the main valve core assembly is located inside the intermediate connecting pipe; the gearbox is rotatably mounted on the intermediate connecting pipe 7; The rack ring 8 is rotatably mounted on the main valve core assembly 28, and an axial force transmission block 12 is radially installed between the rack ring and the main valve core assembly. An annular groove 81 for installing the force transmission block is formed in the rack ring. The lever 10 is rotatably mounted on the gearbox 9 via a pin, and one end of the lever 10 meshes with the rack ring 8 for transmission. A handle 11 is fitted onto the lever 10; the handle 11, lever 10, gearbox 9, and rack ring 8 rotate synchronously around the axis of the main valve core assembly.

[0029] To enable the installation and positioning of the force transmission block, a mounting portion 281 for mounting the rack ring is provided on the main valve core assembly. The mounting portion has a groove 284 for mounting the force transmission block, and an annular groove 81 adapted to the force transmission block 12 is provided inside the rack ring.

[0030] The inflatable connection assembly is connected to the intermediate connecting pipe. The inflatable connection assembly includes a locking sleeve 1, a locking tongue 2, a mating positioning frame 3, a sealing bushing 4, an inflation nozzle 5, and a connecting body 6. The connecting body 6 is connected to the intermediate body 7. An energy storage sealing ring D is installed between the main valve core and the connecting body. The inflation nozzle is installed in the connecting body through the sealing bushing. The inflation nozzle 5 is installed on the side of the inflation nozzle near the main valve core through an inflation nozzle spring 30. The mating positioning frame is connected to the front end of the connecting body. The locking tongue is rotatably mounted on the mating positioning frame. The locking sleeve is installed on the periphery of the mating positioning frame through a spring to press the locking tongue after connecting the receiving device.

[0031] To enable the installation and removal of the main valve core assembly, in one embodiment, the main valve core assembly includes a main valve core 280, a main valve core small-diameter sleeve 282, and a fastening sleeve 283. The main valve core 28 includes a large-diameter portion 2801 and a small-diameter portion 2802, wherein the small-diameter portion is inserted into the movable valve core assembly, and an inclined gas passage 102 is provided at the transition between the large-diameter portion and the small-diameter portion. The main valve core small diameter sleeve 282 is fitted onto the small diameter portion of the main valve core 280. The fastening sleeve is connected to the front end of the small diameter portion by a threaded connection and presses the main valve core small diameter sleeve 282 tightly. The main valve core small diameter sleeve has a gas passage 102, and the gas passage of the main valve core small diameter sleeve and the main valve core are connected. A gap channel 108 is provided between the small-diameter sleeve of the main valve core and the small-diameter portion of the main valve core, one end of which can communicate with the pilot flow channel (e.g., Figure 5 As shown), the other end passes through a gas channel and connects to the main channel of the valve core; for example, the gap channel can be formed by a through groove 2021 opened inside the small diameter sleeve of the main valve core.

[0032] In another embodiment, the drainage spacer may be part of the main valve movable valve core seat or the main valve movable core cover; the drainage hole may be opened at the front end of the main valve movable core cover.

[0033] This invention relates to the control of high-pressure, high-flow-rate gas. By rationally improving the valve core and utilizing a pilot flow channel, the pressure difference across the valve core assists its movement, thereby achieving safe and reliable control of high-pressure, high-flow-rate gas. The improved valve core makes it easier for operators to control high-pressure, high-flow-rate gas, and its use is safer and more controllable. Furthermore, through improvements to the drive assembly and the use of a rack and pinion ring design, the handle can rotate around the main valve core axis, and the valve core movement can be controlled by pushing the handle; this avoids the problem of traditional controllers requiring the handle to be moved when the position is unsuitable.

[0034] In another embodiment, a high-pressure gas high-flow-rate rapid filling control method is provided, which is implemented using the high-pressure gas high-flow-rate rapid filling interface controller, including a gas source disconnection stage and a gas supply stage. The gas supply disconnection stage prevents gas from entering the receiving device from the controller. The specific process is as follows: Holding the upper part of the handle 11, pull the handle backward (towards the air source) to the inclined limit of the gearbox 9. The handle drives the lever 10 to rotate around the positioning pin 31, engaging with the rack ring. Through the force transmission block 12, it drives the main valve core assembly 28 to move to the left (towards the air receiving device) into place. When the main valve core assembly moves to the left, the energy storage seal rings B and C generate friction. Under the combined push of the return force of the valve core reset power component (reset spring) 23, the movable valve core assembly moves to the left. The closing process is as follows: Figure 2 and Figure 4 As shown, in this state, as Figure 3 As shown, high-pressure gas enters the inclined hole of the shroud through the high-pressure hose and the air inlet pipe, then enters the small gap annular hole between the shroud 22 and the movable valve core seat 17, and then enters the pilot groove and the gap between the movable valve core cover 21 and the shroud 22 to form a high-pressure chamber; simultaneously, as Figure 5 As shown, the gas inside the main valve core assembly 28 and at both ends enters the exhaust channel of the intake and exhaust seat through the middle section orifice 107, opening the exhaust valve core 27 and exhaust valve core spring 26 of the exhaust valve, and enters the exhaust pipe 25 to release pressure. If the controller is connected to the gas receiving equipment interface at this time, the one-way valve in the gas receiving equipment will close due to the internal pressure being higher than the input pressure, and the gas inside the input end will be released pressure through the exhaust pipe 25. If the controller is not connected to the gas receiving equipment interface at this time, the inflation nozzle 5, under the force of the inflation nozzle spring 30, contacts the O-ring seal in the sealing bushing 4 to form a seal, and the internal gas is released pressure through the exhaust pipe 25. Under the above conditions, the rear part of the movable valve core cover 21 is in the high-pressure chamber and the pressure relief chamber, generating a forward thrust due to the pressure difference. Under the combined push of the valve core reset power component (reset spring) 23, the movable valve core assembly moves to the left until the sealing surface of the main valve sealing gasket 16 contacts and deforms with the main sealing seat 15, sealing the high-pressure gas, thereby achieving the controller closed state. The fully closed state is shown in the schematic diagram. Figure 4 and Figure 5 As shown.

[0035] The ventilation stage involves allowing the air source to enter the receiving device from the controller. The specific process is as follows: Holding the upper part of the handle 11, push the handle forward to rotate it in a limited position against the inclined surface of the gearbox 9. The handle drives the lever 10 to rotate around the positioning pin 31, engaging with the rack ring 8. Through the force transmission block 12, it drives the main valve core assembly 28 to move to the right (towards the air source) until it contacts the bottom surface of the inner cavity of the main valve movable core cover 21. The opening process is illustrated in the diagram. Figure 6 and Figure 7 As shown; In this state, such as Figure 7 As shown, high-pressure gas is connected to the inlet port pipe 24 through a high-pressure hose, enters the oblique hole of the flow guide shroud 22, then enters the small gap annular hole between the flow guide shroud 22 and the movable valve core seat 17, then enters the gap between the pilot groove and the movable valve core cover 21 and the flow guide shroud 22, the energy storage sealing ring B18 and the energy storage sealing ring C20, and the annular gap of the outer cylindrical surface of the small end of the main valve core assembly 28, and then flows into the main valve core channel of the main valve core assembly 28 through the flow guide hole, forming a pressure reducing chamber in the space behind the small gap annular hole of the movable valve core seat 17.

[0036] At this time, the outer cylindrical surface of the main valve core assembly 28 contacts and seals with the energy storage sealing ring A14 and the energy storage sealing ring D29, forming a sealing channel. If the controller is connected to the gas receiving equipment interface at this time, the one-way valve in the gas receiving equipment will close because the internal pressure is higher than the input pressure. After the internal gas pressure at the input end increases, the one-way valve will open to add gas. If the controller is not connected to the receiving equipment at this time, the inflation nozzle 5 will contact the O-ring in the sealing bushing 4 under the force of the inflation nozzle spring 30 to form a seal.

[0037] In the above circumstances, people such as Figure 7 As shown, when the drainage hood continues to supply gas, the pressure difference between the high-pressure chamber and the low-pressure chamber generates a rightward thrust on the movable valve core seat 17. Under the combined push of the handle, it overcomes the rebound force of the valve core reset power component (reset spring) 23, and the movable valve assembly moves to the right to the main valve sealing gasket 16. The sealing surface of the main valve sealing gasket disengages from the main sealing seat 15, thereby realizing the controller's open state. The fully open state is shown in the diagram. Figure 8 and Figure 9 As shown.

[0038] This invention is used to control high-pressure, high-flow-rate gas. By reasonably improving the valve core, a pilot flow channel is used to assist the movement of the valve core by means of the pressure difference at both ends of the valve core, thereby achieving safe and reliable control of high-pressure, high-flow-rate gas. After the valve core is improved, it is easier for operators to control high-pressure, high-flow-rate gas, and its use is also safer and more controllable.

[0039] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
