Description

Technical Field

[0001] This application relates to the field of gas supply technology, and more particularly to a valve assembly, gas supply device and terminal. Background Technology

[0002] With industrial development, many units in industrial equipment require low-pressure gases. Taking vehicles as an example, tires, in-car massage chairs, oxygen concentrators, and side air supply systems all require low-pressure gases. Therefore, the demand for valve assemblies in vehicles and other industrial equipment is increasing. However, current valve assemblies have low integration, complex structures, and are difficult to maintain. Furthermore, if any sub-gas channel of a valve assembly malfunctions, the entire valve assembly becomes unusable and requires shutdown for maintenance. Utility Model Content

[0003] This application provides a valve assembly, a gas supply device, and a terminal. The valve assembly provided by this application has a high degree of integration, is easy to maintain, and can supply gas to the gas-consuming unit corresponding to the damaged sub-gas channel after one sub-gas channel is damaged.

[0004] The first aspect of this application provides a valve assembly, including: a valve body and a plurality of pressure reducing valves. The valve body can be a metal component having a plurality of sub-gas passages and interconnecting passages. The plurality of pressure reducing valves are all disposed on the valve body, and the number of pressure reducing valves and sub-gas passages is the same. The chambers of the plurality of pressure reducing valves are respectively connected to the plurality of sub-gas passages, and the plurality of sub-gas passages are interconnected through interconnecting passages. The connection between the interconnecting passages and the sub-gas passages is located between the outlets of the pressure reducing valves and the sub-gas passages.

[0005] The inlets of multiple sub-gas channels can be connected to the outlets of the gas source, and the outlets of the multiple sub-gas channels can be connected to the inlets of multiple gas-using units. The valve assembly can be applied to terminals such as vehicles to supply gas to gas-using units such as massage chairs, oxygen concentrators, radar, and vehicle side wings, and can also supply gas to equipment such as inflatable tents, inflatable mattresses, and inflatable seats.

[0006] In this application, after the high-pressure gas supplied by the gas source enters the sub-gas channel, it is reduced to low-pressure gas by the pressure reducing valve. The low-pressure gas is supplied to the gas-using unit. Each sub-gas channel can supply gas to one gas-using unit so that the gas-using unit can work normally.

[0007] Traditionally, each pressure-reducing valve requires a separate valve body, and multiple valve bodies need to be connected by pipelines. This results in a very complex valve assembly structure, and maintenance of the valve assembly requires inspection of numerous valve bodies, pressure-reducing valves, and pipelines, leading to high maintenance difficulty and cost. In this application, multiple pressure-reducing valves are integrated into a single valve body, achieving a high degree of integration. When the valve assembly requires maintenance and inspection, multiple pressure-reducing valves can be maintained and inspected on a single valve body, reducing maintenance difficulty and cost.

[0008] In this application, multiple sub-gas channels are interconnected through multiple interconnecting channels. When the pressure reducing valve corresponding to one sub-gas channel fails, gas can be supplied to the gas-consuming unit corresponding to the damaged sub-gas channel through other sub-gas channels. In other words, the multiple sub-gas channels can serve as backups for each other, achieving gas supply redundancy. With this design, even if the pressure reducing valve of one sub-gas channel fails, the valve assembly can still be used normally without shutdown for maintenance, extending the service life of the valve assembly and saving resources.

[0009] In this application, multiple sub-gas channels are interconnected through multiple interconnecting channels, which also allows multiple sub-gas channels to supply gas to a gas-consuming unit simultaneously, thus supporting the multi-channel gas demand of a gas-consuming unit. This eliminates the need to set up multiple sub-gas channels separately for a gas-consuming unit, simplifies the structure of the valve assembly, and saves resources.

[0010] In some possible implementations, the valve assembly also includes a sub-switch valve, which is located in the interconnection channel. When the sub-switch valve is in the open state, multiple sub-gas channels are interconnected through the interconnection channel.

[0011] In the above implementation method, by setting a sub-switching valve, when it is not necessary to connect multiple sub-gas channels, the sub-switching valve is closed to disconnect multiple sub-gas channels and avoid gas crosstalk between multiple sub-gas channels.

[0012] In some possible implementations, at least some of the sub-gas channels are equipped with pressure relief valves. When the pressure relief valves are in the open state, the sub-gas channels are connected to the external environment through the pressure relief valves.

[0013] In the above implementation, when the gas pressure in the sub-gas channel exceeds the first threshold, the pressure relief valve opens, connecting the sub-gas channel to the external environment. This allows the gas in the sub-gas channel to flow to the external environment, thereby reducing the gas pressure in the sub-gas channel and preventing excessive pressure, thus improving the safety factor. When the gas pressure in the sub-gas channel is less than the first threshold, the pressure relief valve closes, and the sub-gas channel can continue to operate normally.

[0014] In some possible implementations, the valve assembly also includes a sub-safety valve, which is disposed in the valve body. The chamber of the sub-safety valve is connected to at least a portion of the sub-gas passage. When the sub-safety valve is in the open state, the sub-gas passage is connected to the external environment through the chamber of the sub-safety valve.

[0015] In the above implementation, when the gas pressure in the sub-gas channel is greater than the second threshold, the sub-safety valve opens, and the sub-gas channel is connected to the external environment through the sub-safety valve, so that the gas in the sub-gas channel flows to the external environment, thereby reducing the gas pressure in the sub-gas channel, avoiding excessive gas pressure in the sub-gas channel, and improving the safety factor.

[0016] In some possible implementations, the valve assembly is equipped with both a pressure relief valve and a sub-safety valve. When the gas pressure in the sub-gas passage is greater than or equal to a first threshold and less than a second threshold, the pressure relief valve releases pressure, allowing the sub-gas passage to continue operating normally. When the gas pressure in the sub-gas passage is greater than or equal to the second threshold, the pressure in the sub-gas passage is too high, posing a risk of explosion. In this case, the sub-safety valve opens to rapidly release pressure, preventing an explosion.

[0017] In some possible implementations, at least some of the sub-gas channels are equipped with sub-pressure sensors.

[0018] In the above implementation, the sub-pressure sensor can detect the gas pressure in the sub-gas channel in order to detect whether the gas pressure in the sub-gas channel is positive.

[0019] In some possible implementations, the valve assembly also includes a gas distribution controller, which is located in the valve body and is used to control the opening degree of the pressure reducing valve based on the gas pressure value detected by the sub-pressure sensor.

[0020] In the above implementation, the gas distribution controller can acquire the gas pressure detected by the sub-pressure sensor and determine whether the gas pressure is equal to the preset gas pressure. If the gas pressure is less than the preset gas pressure, the gas distribution controller can increase the opening of the pressure reducing valve to increase the gas pressure in the sub-gas channel. If the gas pressure is greater than the preset gas pressure, the gas distribution controller can decrease the opening of the pressure reducing valve to decrease the gas pressure in the sub-gas channel. By setting the sub-pressure sensor and the gas distribution controller, the gas pressure in the sub-gas channel can be dynamically adjusted to ensure that the gas pressure in the sub-gas channel is always in an optimal state, thereby improving gas utilization and avoiding resource waste.

[0021] In some possible implementations, the inlets of multiple sub-gas channels are connected to the outlets of multiple gas sources, respectively.

[0022] In the above implementation, each sub-gas channel is equipped with a corresponding gas source. Since multiple sub-gas channels are interconnected, when one of the sub-gas channels is connected to a gas source that is not in use, gas can be supplied through another gas source connected to it, thereby increasing the reliability of the gas supply.

[0023] In some possible implementations, the valve body is also provided with a main gas passage, which includes an inlet and multiple outlets. The inlet of the main gas passage is used to connect with the outlet of the gas source, and the multiple outlets of the main gas passage are respectively connected to the inlets of multiple sub-gas passages.

[0024] In the above implementation method, multiple sub-gas channels share a single gas source, which can save resources.

[0025] In some possible implementations, the valve assembly also includes a master switch valve, which is located in the valve body. One end of the master switch valve is connected to the outlet of the gas source, and the other end is connected to the inlet of the main gas passage. When the master switch valve is in the open state, the gas source and the main gas passage are connected.

[0026] In the above implementation, when any gas-consuming unit needs gas, the main switch valve can be opened, allowing gas from the gas source to enter the main gas channel via the main switch valve, and then from the main gas channel to the sub-gas channel, so that the sub-gas channel can smoothly supply gas to the gas-consuming unit. When the gas-consuming unit does not need gas, the main switch valve can be closed to prevent gas leakage from the gas source and increase the safety factor.

[0027] In some possible implementations, the valve assembly also includes a main safety valve, which is located in the valve body. The chamber of the main safety valve is connected to the main gas passage. When the main safety valve is in the open state, the main gas passage is connected to the external environment through the chamber of the main safety valve.

[0028] In the above implementation, when the gas pressure in the main gas channel is greater than the safety threshold, the main safety valve opens, and the main gas channel is connected to the external environment through the main safety valve, so that the gas in the main gas channel flows to the external environment, thereby reducing the gas pressure in the main gas channel, avoiding excessive gas pressure in the main gas channel, and improving the safety factor.

[0029] In some possible implementations, the valve assembly also includes a total pressure sensor located in the main gas passage.

[0030] In the above implementation, the total pressure sensor can detect the gas pressure in the total gas channel.

[0031] The second aspect of this application provides a gas supply device, including a gas source and any of the valve assemblies in the first aspect of this application, wherein the outlet of the gas source is connected to the inlet of a plurality of sub-gas channels.

[0032] A third aspect of this application provides a terminal that includes a valve assembly according to any one of the first aspects of this application, or a gas supply device according to the second aspect of this application.

[0033] Among some possible implementations, the terminal includes one of the following: a vehicle, a robot, and a drone.

[0034] The technical effects of the second and third aspects of this application are the same as those of the first aspect. Attached Figure Description

Detailed Implementation

[0058] The embodiments of this application are described below with reference to the accompanying drawings.

[0059] The use of prefixes such as "first" and "second" in this scheme is solely for distinguishing different descriptive objects and does not limit the position, order, priority, quantity, or content of the described objects. For example, the described object is not limited by the prefix and can be one or more; taking "first device" as an example, "device" can be one or more. Furthermore, the objects modified by different prefixes can be the same or different. For example, if the described object is "device," then "first device" and "second device" can be the same device, the same type of device, or different types of devices. In summary, the use of prefixes to distinguish descriptive objects in this application does not constitute a limitation on the described objects. The description of the described objects is given in the claims or the context of the embodiments, and the use of such prefixes should not constitute unnecessary restrictions.

[0060] To facilitate understanding, the relevant terms that may be involved in the embodiments of this application will be introduced below.

[0061] Pressure reducing valve: It is a control valve that reduces the high pressure of the fluid on the inlet side to the stable low pressure required on the outlet side by adjusting the pressure of the gas, and maintains the outlet pressure basically constant when the inlet pressure fluctuates.

[0062] On / off valve: A valve used to control the flow of gas. Its core function is to "connect" or "cut off" the gas pipeline by the action of the valve core (fully open or fully closed).

[0063] Pressure relief valve: It is an automatic valve used to prevent the pressure in a gas system from exceeding the safety limit. When the system pressure rises to the set safety threshold, it will automatically open and release some gas, so that the pressure drops to a safe range and then automatically closes. This avoids pipeline rupture or equipment damage caused by overpressure and is a key protective device to ensure the safe operation of the gas system.

[0064] Safety valve: A device that can quickly release excess pressure in a gas system.

[0065] The above explanations of the terminology can be applied to the embodiments described below.

[0066] refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a gas supply device 1100 provided in an embodiment of this application. Figure 2This is a structural block diagram of a gas supply device 1100 provided in an embodiment of this application. The gas supply device 1100 includes a valve assembly 100 and a gas source 200. The valve assembly 100 includes a valve body 10 and multiple pressure reducing valves 20. The valve body 10 is provided with multiple sub-gas channels 110 and interconnecting channels 120. "Multiple" refers to two or more sub-gas channels 110 and pressure reducing valves 20, with the same number of sub-gas channels 110 and pressure reducing valves 20. In this embodiment, two pressure reducing valves 20 and two sub-gas channels 110 are used as an example. The valve body 10 can be a structural component made of metal or other materials. Multiple sub-gas channels 110 provided on the valve body 10 each have an inlet and an outlet. The inlets of the multiple sub-gas channels 110 are used to connect with the outlets of the gas source 200. The gas source 200 can be a high-pressure gas tank. The sub-gas channels 110 and the gas source 200 can be connected via pipes. For example, the multiple sub-gas channels 110 can share a single gas source 200. The valve body 10 can also be provided with a main gas channel 130, which has one inlet and multiple outlets. The inlet of the main gas channel 130 and the outlets of the gas source 200 are connected via pipes. The multiple outlets of the main gas channel 130 are respectively connected to the inlets of the multiple sub-gas channels 110. Figure 1 A dashed line is used to delineate the boundary between the main gas channel 130 and the sub-gas channels 110. Multiple sub-gas channels 110 share a single gas source 200, saving resources and reducing costs. The outlets of the multiple sub-gas channels 110 are respectively used to connect to the inlets of multiple low-pressure gas-consuming units 300. The sub-gas channels 110 and the gas-consuming units 300 can be connected via pipes. All inlets and outlets are located on the same plane of the valve body 10 to facilitate connection between the gas source 200 and the gas-consuming units 300.

[0067] Figure 1 and Figure 2 The purpose of this illustration is solely to depict the connection relationship between the valve body 10, pressure reducing valve 20, air source 200, and air-consuming unit 300, and is not to specifically limit the connection positions, specific structures, or quantities of each device. Furthermore, the structures illustrated in this application's embodiments do not constitute a specific limitation on the air supply device 1100. In other embodiments of this application, the air supply device 1100 may include more or fewer components than illustrated, or combine certain components, or split certain components, or have different component arrangements. The illustrated components may be implemented in hardware, software, or a combination of both.

[0068] The air supply device 1100 can be applied to terminals such as vehicles, and the air-using unit 300 can be a massage chair. The massage chair can be the driver's seat or other passenger seats in a vehicle. The airbags in the massage chair can be inflated to massage the passenger's body parts. The inflation and deflation function of the massage chair, through the cyclical operation of the airbags, simulates the squeezing, wrapping, and kneading movements of human hand massage. Its core functions include supplementing massage blind spots, stabilizing the body, promoting blood circulation, relieving muscle tension, and assisting in stretching and relaxation.

[0069] The air intake unit 300 can also serve as a vehicle side wing. During high-speed driving, the airflow can be guided through the exhaust from the side wing to achieve functions such as heat dissipation, noise reduction, and improved aerodynamic performance. The side wing exhaust can also function as an active anti-rollover system. Sensors can monitor the vehicle's lateral tilt angle and steering behavior in real time. When a rollover risk is detected, the system injects air into the opposite side of the tilt direction, generating thrust to counteract the roll moment and restore vehicle balance.

[0070] The 300 air-generating unit can also function as an oxygen concentrator. An oxygen concentrator in a vehicle is a device that uses specific technology to separate oxygen from the air, providing a high concentration of oxygen to the occupants or equipment. For example, in high-altitude areas above 3000 meters, the thin air leads to low oxygen levels, easily triggering altitude sickness (such as headaches, fatigue, and insomnia). A vehicle oxygen concentrator can provide a high concentration of oxygen in real time, alleviating symptoms of hypoxia and ensuring driving safety.

[0071] The air unit 300 can also serve as a radar cleaning device. When a vehicle is traveling at high speed, flying insects can easily collide with the radar lens, causing dirt to accumulate. The radar cleaning device can quickly blow away the dirt adhering to the radar lens through gas jets, allowing the radar to function normally.

[0072] The air unit 300 can also power peripheral devices such as inflatable tents, inflatable mattresses, and inflatable seats.

[0073] For example, the pressure reducing valve 20 may include a valve seat, a valve disc, a piston, a spring, and an electromagnetic actuator. The valve seat has a chamber and an inlet and an outlet communicating with the chamber. The valve disc, diaphragm, and spring are all disposed within the chamber of the valve seat. The electromagnetic actuator can drive the valve disc to move via the piston, causing the spring to extend and retract, thus changing the opening degree of the valve disc in the pressure reducing valve 20. When the thrust of the piston and the elastic force of the spring are balanced, the opening degree of the valve disc remains constant.

[0074] Multiple pressure reducing valves 20 are disposed within the valve body 10, and the chambers of the multiple pressure reducing valves 20 are respectively connected to multiple sub-gas channels 110. Exemplarily, the valve body 10 may have multiple receiving cavities (not shown), each connected to multiple sub-gas channels 110. The valve seats and other components of the pressure reducing valves 20 are installed within these receiving cavities, and the inlet and outlet ports on the valve seats are both connected to the sub-gas channels 110. Optionally, the pressure reducing valves 20 may be partially located within the receiving cavities, with another portion exposed outside the valve body 10.

[0075] Multiple sub-gas channels 110 are interconnected through interconnecting channels 120, and the connection between interconnecting channels 120 and sub-gas channels 110 is located between the pressure reducing valve 20 and the outlet of sub-gas channels 110, that is, multiple sub-gas channels 110 are interconnected after the pressure reducing valve 20.

[0076] In this embodiment, the high-pressure gas provided by the gas source 200 enters the sub-gas channel 110 and is reduced to low-pressure gas by the pressure reducing valve 20. The low-pressure gas is provided to the gas-using unit 300. Each sub-gas channel 110 can provide gas to one gas-using unit 300 so that the gas-using unit 300 can work normally.

[0077] Traditionally, each pressure reducing valve 20 requires a valve body 10, and multiple valve bodies 10 need to be connected by pipelines. This results in a very complex structure for the valve assembly 100, and maintenance of the valve assembly 100 requires inspection of a large number of valve bodies 10, pressure reducing valves 20, and pipelines, leading to high maintenance difficulty and cost. In this embodiment, multiple pressure reducing valves 20 are integrated onto a single valve body 10, achieving a high degree of integration. When the valve assembly 100 needs maintenance and inspection, multiple pressure reducing valves 20 can be maintained and inspected on a single valve body 10, reducing maintenance difficulty and cost.

[0078] Furthermore, in this embodiment, multiple sub-gas channels 110 are interconnected through multiple interconnecting channels 120. When the pressure reducing valve of one sub-gas channel 110 fails, gas can be supplied to the gas-consuming unit 300 corresponding to the damaged sub-gas channel 110 through other sub-gas channels 110. That is, the multiple sub-gas channels 110 can serve as backups for each other, achieving gas supply redundancy. With this design, when the pressure reducing valve 20 of one sub-gas channel 110 fails, the valve assembly 100 can still be used normally without shutdown for maintenance, extending the service life of the valve assembly 100 and saving resources.

[0079] In this embodiment, multiple sub-gas channels 110 are interconnected through multiple interconnecting channels 120, which also allows multiple sub-gas channels 110 to supply gas to a gas-consuming unit 300 at the same time, so as to support the multiple gas consumption needs of a gas-consuming unit 300. There is no need to set up multiple sub-gas channels 110 separately for a gas-consuming unit 300, which can simplify the structure of the valve assembly 100 and save resources.

[0080] For example, refer to Figure 3 , Figure 3 for Figure 2 The diagram shows a structural block diagram of one gas supply method of the gas supply device 1100. Two sub-gas channels 110 are designated as first sub-gas channel 111 and second sub-gas channel 112, respectively. The two gas-consuming units 300 corresponding to the two sub-gas channels 110 are designated as first gas-consuming unit 301 and second gas-consuming unit 302, respectively. The outlet of the first sub-gas channel 111 is connected to the inlet of the first gas-consuming unit 301. Under normal circumstances, the first sub-gas channel 111 supplies gas to the first gas-consuming unit 301, and the second sub-gas channel 112 supplies gas to the second gas-consuming unit 302. When the first gas-consuming unit 301 needs gas and the second gas-consuming unit 302 does not need gas, the inlet of the second gas-consuming unit 302 is closed, preventing gas from the first sub-gas channel 111 from entering the second gas-consuming unit 302 through the interconnection channel 120. Similarly, when the second gas-using unit 302 needs gas and the first gas-using unit 301 does not need gas, the air inlet of the first gas-using unit 301 is closed, which can prevent the gas from the second sub-gas channel 112 from entering the first gas-using unit 301 through the interconnection channel 120.

[0081] refer to Figure 3 When the pressure reducing valve of the second sub-gas channel 112 fails, gas can be supplied to the second gas-consuming unit 302 through the first sub-gas channel 111. For example, the high-pressure gas supplied by the gas source 200 enters the first sub-gas channel 111 from the inlet. The high-pressure gas is reduced to low-pressure gas by the pressure reducing valve 20 corresponding to the first sub-gas channel 111, and then flows from the first inlet channel into the interconnecting channel 120, then from the interconnecting channel 120 into the second sub-gas channel 112, and finally from the outlet of the second sub-gas channel 112 into the second gas-consuming unit 302. Figure 3 The arrows in the diagram indicate the direction of gas flow. Similarly, when the pressure reducing valve of the first sub-gas channel 111 fails, gas can be supplied to the first gas-consuming unit 301 through the second sub-gas channel 112.

[0082] refer to Figure 4 , Figure 4 for Figure 2The diagram shows another gas supply method of the gas supply device 1100. When the first gas-consuming unit 301 requires two gas sources simultaneously, the first sub-gas channel 111 and the second sub-gas channel 112 can simultaneously supply gas to the first gas-consuming unit 301 to meet its gas demand. Similarly, when the second gas-consuming unit 302 requires two gas sources simultaneously, the first sub-gas channel 111 and the second sub-gas channel 112 can simultaneously supply gas to the second gas-consuming unit 302. Figure 4 The arrows in the diagram indicate the direction of gas flow.

[0083] In some embodiments, reference is made to Figure 5 , Figure 5 This is a structural block diagram of another gas supply device 1100 provided in an embodiment of this application. The valve assembly 100 also includes a sub-switching valve 30, which is disposed in the interconnection channel 120. When the sub-switching valve 30 is in the open state, the sub-gas channels 110 are interconnected through multiple interconnection channels 120. By providing the sub-switching valve 30, when it is not necessary for multiple sub-gas channels 110 to be connected, the sub-switching valve 30 can be closed to disconnect the multiple sub-gas channels 110, thereby preventing gas crosstalk between the multiple sub-gas channels 110.

[0084] For example, when the pressure reducing valve 20 of the first sub-gas channel 111 fails, the sub-switch valve 30 can be opened to allow gas from the gas source 200 to be supplied to the first gas-consuming unit 301 via the second sub-gas channel 112, the interconnecting channel 120, and the first sub-gas channel 111. When the pressure reducing valve 20 of the second sub-gas channel 112 fails, the sub-switch valve 30 can be opened to allow gas from the gas source 200 to be supplied to the second gas-consuming unit 302 via the first sub-gas channel 111, the interconnecting channel 120, and the second sub-gas channel 112. By setting the sub-switch valve 30, when there is no need for the first sub-gas channel 111 and the second sub-gas channel 112 to be connected, the sub-switch valve 30 can be closed to disconnect the first sub-gas channel 111 and the second sub-gas channel 112, thus preventing crosstalk between the gas in the first sub-gas channel 111 and the gas in the second sub-gas channel 112.

[0085] In some embodiments, reference is made to Figure 6 , Figure 6This is a structural block diagram of another gas supply device 1100 provided in an embodiment of this application. At least a portion of the sub-gas channels 110 are equipped with pressure relief valves 40. When the pressure relief valves 40 are open, the sub-gas channels 110 are connected to the external environment through the pressure relief valves 40. The pressure relief valves 40 are connected between the pressure reducing valve 20 and the outlet of the sub-gas channel 110. Exemplarily, both sub-gas channels 110 are equipped with pressure relief valves 40. Optionally, only one sub-gas channel 110 may be equipped with a pressure relief valve 40. When the gas pressure in the sub-gas channel 110 is greater than a first threshold, the pressure relief valve 40 opens, and the sub-gas channel 110 is connected to the external environment through the pressure relief valve 40, allowing the gas in the sub-gas channel 110 to flow to the external environment, thereby reducing the gas pressure in the sub-gas channel 110 and preventing excessive gas pressure, thus improving the safety factor. When the gas pressure in the sub-gas channel 110 is less than the first threshold, the pressure relief valve 40 closes, and the sub-gas channel 110 can continue to operate normally.

[0086] In some embodiments, reference is made to Figure 7 , Figure 7 This is a structural block diagram of another gas supply device 1100 provided in an embodiment of this application. The valve assembly 100 also includes a sub-safety valve 50, which is disposed in the valve body 10. The chamber of the sub-safety valve 50 is connected to at least a portion of the sub-gas passage 110. When the sub-safety valve 50 is in the open state, the sub-gas passage 110 is connected to the external environment through the chamber of the sub-safety valve 50. The sub-safety valve 50 is disposed between the pressure reducing valve 20 and the outlet of the sub-gas passage 110. Exemplarily, both sub-gas passages 110 are connected to the chamber of the sub-safety valve 50. Optionally, the sub-safety valve 50 may be configured to be connected to only one of the sub-gas passages 110. When the gas pressure in the sub-gas passage 110 is greater than a second threshold, the sub-safety valve 50 opens, and the sub-gas passage 110 is connected to the external environment through the sub-safety valve 50, so that the gas in the sub-gas passage 110 flows to the external environment, thereby reducing the gas pressure in the sub-gas passage 110, preventing the gas pressure in the sub-gas passage 110 from becoming too high, and improving the safety factor.

[0087] In some embodiments, reference is made to Figure 8 , Figure 8 This is a structural block diagram of another gas supply device 1100 provided in an embodiment of this application. The valve assembly 100 may simultaneously include a pressure relief valve 40 and a sub-safety valve 50. When the gas pressure in the sub-gas passage 110 is greater than a first threshold, the pressure relief valve 40 opens; when the gas pressure in the sub-gas passage 110 is greater than a second threshold, the sub-safety valve 50 opens. The second threshold is greater than the first threshold. The normal operating gas pressure of the sub-gas passage 110 is less than the first threshold. For example, if the normal operating gas pressure of the sub-gas passage 110 is 2 bar, the first threshold can be 4 bar, and the second threshold can be 8 bar.

[0088] If only the pressure relief valve 40 is installed, when the pressure in the sub-gas passage 110 is very high, the pressure relief rate of the valve 40 cannot keep up with the rate of pressure increase in the sub-gas passage 110, which may lead to an explosion. If only the sub-safety valve 50 is installed, the pressure in the sub-gas passage 110 will not be controlled when it is between the first and second threshold values, causing the pressure in the sub-gas passage 110 to gradually increase to a value greater than or equal to the second threshold value. At this point, the sub-safety valve 50 will open to rapidly relieve pressure. Once the sub-safety valve 50 opens, the sub-gas passage 110 will no longer be able to operate normally.

[0089] In this embodiment, a pressure relief valve 40 and a sub-safety valve 50 are simultaneously provided. When the gas pressure in the sub-gas channel 110 is greater than or equal to a first threshold and less than a second threshold, the pressure relief valve 40 releases pressure, allowing the sub-gas channel 110 to continue operating normally. When the gas pressure in the sub-gas channel 110 is greater than or equal to the second threshold, the pressure in the sub-gas channel 110 is too high, posing a risk of explosion. In this case, the sub-safety valve 50 opens to rapidly release pressure, preventing an explosion.

[0090] In some embodiments, reference is made to Figure 9 , Figure 9 This is a structural block diagram of another gas supply device 1100 provided in an embodiment of this application. At least a portion of the sub-gas channels 110 are equipped with sub-pressure sensors 60. Exemplarily, both sub-gas channels 110 are equipped with sub-pressure sensors 60. Optionally, only one sub-gas channel 110 may be equipped with a sub-pressure sensor 60. Exemplarily, the sub-pressure sensor 60 may be integrated into the pressure reducing valve 20. Optionally, the sub-pressure sensor 60 may also be provided independently. The sub-pressure sensor 60 can detect the gas pressure of the sub-gas channels 110 to detect whether the gas pressure of the sub-gas channels 110 is normal. For example, the gas pressure detected by the sub-pressure sensor 60 can be displayed on a monitor, allowing the user to check whether the gas pressure of the sub-gas channels 110 is normal. When the gas pressure is lower than a preset gas pressure, it can be determined that the gas channel may be leaking; when the gas pressure is higher than the preset gas pressure, it can be determined that the gas channel may be overpressured.

[0091] In some embodiments, reference is made to Figure 9 The valve assembly 100 also includes a gas distribution controller 400, which is disposed in the valve body 10. The gas distribution controller 400 is used to control the opening degree of the pressure reducing valve 20 based on the gas pressure value detected by the sub-pressure sensor 60. Both the sub-pressure sensor 60 and the pressure reducing valve 20 are electrically connected to the gas distribution controller 400. Figure 9The dashed lines represent electrical connections. The gas distribution controller 400 can acquire the gas pressure detected by the sub-pressure sensor 60 and determine whether the gas pressure is equal to the preset gas pressure. If the gas pressure is less than the preset gas pressure, the gas distribution controller 400 can control the opening of the pressure reducing valve 20 to increase the gas pressure in the sub-gas channel 110. If the gas pressure is greater than the preset gas pressure, the gas distribution controller 400 can control the opening of the pressure reducing valve 20 to decrease the gas pressure in the sub-gas channel 110. By setting the sub-pressure sensor 60 and the gas distribution controller 400, the gas pressure in the sub-gas channel 110 can be dynamically adjusted to ensure that the gas pressure in the sub-gas channel 110 is always in an optimal state, thereby improving gas utilization and avoiding resource waste.

[0092] In some embodiments, reference is made to Figure 10 , Figure 10 This is a structural block diagram of another gas supply device 1100 provided in an embodiment of this application. The valve assembly 100 also includes a main switch valve 70, which is disposed on the valve body 10. One end of the main switch valve 70 is connected to the outlet of the gas source 200, and the other end is connected to the inlet of the main gas channel 130. When the main switch valve 70 is open, the gas source 200 and the main gas channel 130 are connected. When any gas-consuming unit 300 needs gas, the main switch valve 70 can be opened, allowing gas from the gas source 200 to enter the main gas channel 130 via the main switch valve 70, and then from the main gas channel 130 to the sub-gas channel 110, enabling the sub-gas channel 110 to smoothly supply gas to the gas-consuming unit 300. When the gas-consuming unit 300 does not need gas, the main switch valve 70 can be closed to prevent gas leakage from the gas source 200 and increase the safety factor.

[0093] In some embodiments, reference is made to Figure 10 The valve assembly 100 also includes a main safety valve 80, which is disposed in the valve body 10. The chamber of the main safety valve 80 is connected to the main gas passage 130. When the main safety valve 80 is in the open state, the main gas passage 130 is connected to the external environment through the chamber of the main safety valve 80. When the gas pressure in the main gas passage 130 exceeds the safety threshold, the main safety valve 80 opens, and the main gas passage 130 is connected to the external environment through the main safety valve 80, so that the gas in the main gas passage 130 flows to the external environment, thereby reducing the gas pressure in the main gas passage 130, preventing the gas pressure in the main gas passage 130 from becoming too high, and improving the safety factor.

[0094] In some embodiments, reference is made to Figure 10The valve assembly 100 also includes a total pressure sensor 90, which is located in the main gas passage 130. The total pressure sensor 90 can detect the gas pressure in the main gas passage 130 to determine whether the gas pressure in the main gas passage 130 is normal. For example, the gas pressure detected by the total pressure sensor 90 can be displayed on a monitor, and the user can check whether the gas pressure in the main gas passage 130 is normal on the monitor.

[0095] In some embodiments, reference is made to Figure 11 , Figure 11 This is a structural block diagram of another gas supply device 1100 provided in an embodiment of this application. The inlets of multiple sub-gas channels 110 are respectively connected to the outlets of multiple gas sources 200. That is, each sub-gas channel 110 is correspondingly provided with a gas source 200. Because the multiple sub-gas channels 110 are interconnected, when one of the sub-gas channels 110 is connected to a gas source 200 without gas, gas can be supplied through another gas source 200 connected to it, thereby increasing the reliability of the gas supply.

[0096] In the above embodiments, there are two pressure reducing valves 20, two sub-gas channels 110, and two gas consumption units 300. In other embodiments, there may be three, four, five, or six pressure reducing valves 20, two sub-gas channels 110, and two gas consumption units 300, etc. This application does not limit the specific number of pressure reducing valves 20, two sub-gas channels 110, and two gas consumption units 300.

[0097] Several implementation methods are described using four pressure reducing valves 20, four sub-gas channels 110, and four gas consumption units 300 as an example.

[0098] In one possible implementation, refer to Figure 12 , Figure 12 This is a structural block diagram of another gas supply device 1100 provided in an embodiment of this application. The valve assembly 100 includes a valve body 10, four pressure reducing valves 20, three sub-switching valves 30, four sub-pressure sensors 60, a main switching valve 70, a main safety valve 80, a main pressure sensor 90, and a gas distribution controller 400.

[0099] The valve body 10 has four sub-gas channels 110 and one main gas channel 130. Each of the four sub-gas channels 110 is equipped with a pressure reducing valve 20. Any two adjacent sub-gas channels 110 are connected by an interconnecting channel 120, resulting in three interconnecting channels 120. Three sub-switching valves 30 are respectively located in the three interconnecting channels 120. Four sub-pressure sensors 60 are respectively located in the four sub-gas channels 110. The four sub-gas channels 110 share a common gas source 200. The outlet of the gas source 200 is connected to one end of the main switching valve 70, and the other end of the main switching valve 70 is connected to the inlet of the main gas channel 130. The four outlets of the main gas channel 130 are respectively connected to the inlets of the four sub-gas channels 110, and the outlets of the four sub-gas channels 110 are respectively connected to the inlets of the four gas-consuming units 300. A main safety valve 80 and a main pressure sensor 90 are located in the main gas channel 130.

[0100] Four pressure reducing valves 20, three sub-switching valves 30, four sub-pressure sensors 60, a main switching valve 70, a main safety valve 80, and a main pressure sensor 90 are all electrically connected to the gas distribution controller 400. Figure 12 The dashed lines represent electrical connections. The gas distribution controller 400 can perform the following operations: control the opening degree of the pressure reducing valve 20 according to the gas demand of the gas-consuming unit 300; control the opening or closing of the sub-switching valve 30; acquire the gas pressure detected by the sub-pressure sensor 60 and adjust the opening degree of the pressure reducing valve 20 according to the gas pressure detected by the sub-pressure sensor 60; control the opening degree of the main switching valve 70; control the opening or closing of the main safety valve 80; acquire the gas pressure of the main pressure sensor 90 and control the opening or closing of the main safety valve 80 according to the gas pressure detected by the main pressure sensor 90.

[0101] In the above embodiments, reference is made to Figure 13 , Figure 13 for Figure 12 The diagram shows a structural block diagram of one gas supply method of the gas supply device 1100. The four sub-gas channels 110 are designated as first sub-gas channel 111, second sub-gas channel 112, third sub-gas channel 113, and fourth sub-gas channel 114. The three interconnecting channels 120 are designated as first interconnecting channel 121, second interconnecting channel 122, and third interconnecting channel 123. The three sub-switching valves 30 are designated as first sub-switching valve 31, second sub-switching valve 32, and third sub-switching valve 33. The four gas-consuming units 300 are designated as first gas-consuming unit 301, second gas-consuming unit 302, third gas-consuming unit 303, and fourth gas-consuming unit 304.

[0102] Optionally, refer to Figure 13 , Figure 13The arrows indicate the gas flow direction. When the pressure reducing valve 20 corresponding to the first sub-gas channel 111 fails, the first sub-switch valve 31 can be opened, allowing the first sub-gas channel 111 and the second sub-gas channel 112 to connect through the first interconnecting channel 121. At this time, gas can be supplied to the first gas-consuming unit 301 through the second sub-gas channel 112. For example, the gas supplied by the gas source 200 flows sequentially through the main gas channel 130, the second sub-gas channel 112, the first interconnecting channel 121, and the first sub-gas channel 111 to the first gas-consuming unit 301. Similarly, when the pressure reducing valve 20 of the second sub-gas channel 112 fails, gas can be supplied to the second gas-consuming unit 302 through the first sub-gas channel 111.

At this time, gas can be supplied to the first gas-consuming unit 301 through the third sub-gas channel 113. For example, the gas supplied by the gas source 200 flows sequentially through the main gas channel 130, the third sub-gas channel 113, the second interconnecting channel 122, the second sub-gas channel 112, and the first sub-gas channel 111 to the first gas-consuming unit 301.

At this time, gas can be supplied to the first gas-consuming unit 301 through the fourth sub-gas channel 114. For example, the gas supplied by the gas source 200 flows to the first gas-consuming unit 301 sequentially through the main gas channel 130, the fourth sub-gas channel 114, the third interconnecting channel 123, the third sub-gas channel 113, the second interconnecting channel 122, the second sub-gas channel 112, and the first sub-gas channel 111. Similarly, when the pressure reducing valve 20 of the fourth sub-gas channel 114 fails, gas can be supplied to the fourth gas-consuming unit 304 through the first sub-gas channel 111.

[0105] Optionally, refer to Figure 16 , Figure 16 for Figure 12 The diagram shows a structural block diagram of another gas supply method for the gas supply device 1100 shown. Figure 16 The arrows in the diagram indicate the direction of gas flow. When the first gas-using unit 301 needs to use four gas channels simultaneously, the first sub-switch valve 31, the second sub-switch valve 32, and the third sub-switch valve 33 can be opened, so that the first sub-gas channel 111 and the second sub-gas channel 112 are connected through the first interconnecting channel 121, the second sub-gas channel 112 and the third sub-gas channel 113 are connected through the second interconnecting channel 122, and the third sub-gas channel 113 and the fourth sub-gas channel 114 are connected through the third interconnecting channel 123. At this time, the first sub-gas channel 111, the second sub-gas channel 112, the third sub-gas channel 113, and the fourth sub-gas channel 114 can all supply gas to the first gas-using unit 301. Optionally, when the second gas-using unit 302, the third gas-using unit 303, or the fourth gas-using unit 304 needs to use four gas channels simultaneously, the first sub-gas channel 111 to the fourth sub-gas channel 114 can also be used to supply gas to the second gas-using unit 302, the third gas-using unit 303, or the fourth gas-using unit 304 simultaneously. Optionally, when the first gas-using unit 301 needs to use two or three gas channels simultaneously, any two or three channels from the first sub-gas channel 111 to the fourth sub-gas channel 114 can be used to supply gas to the first gas-using unit 301.
