Description

Technical Field

[0001] This application belongs to the field of gas cylinder valves, specifically relating to a cylinder valve that is easy to install and a gas supply system using it. Background Technology

[0002] The hydrogen supply system on a hydrogen fuel cell vehicle can be divided into two parts: one is the on-board high-pressure hydrogen supply system, which is generally provided by a gas cylinder supplier or a hydrogen supply system supplier; the other is the low-pressure hydrogen supply system, which is generally integrated into the fuel cell engine.

[0003] The hydrogen system of a hydrogen fuel cell mainly includes:

[0004] Hydrogen storage module: A hydrogen storage module is a component specifically designed to store hydrogen gas, and it is an important part of the hydrogen supply system in a hydrogen fuel cell vehicle. Specifically, the hydrogen storage module includes core elements such as high-pressure composite material cylinders, cylinder supports, and connecting pipelines. Each cylinder is equipped with a cylinder valve, and the cylinders are connected in parallel through pipelines.

[0005] Hydrogen refueling module: Includes a hydrogen refueling port and a high-pressure gauge. The hydrogen refueling port integrates a hydrogen nozzle, filter, and one-way valve. The hydrogen refueling module can also be integrated with a high-pressure exhaust valve upon user request, for gas replacement within the cylinder and for actively releasing high-pressure hydrogen from the cylinder during vehicle maintenance and repair.

[0006] Pressure regulating module (combination valve): Highly integrated and powerful, it significantly simplifies hydrogen systems. The combination valve internally includes components such as a filter, pressure reducing valve, low-pressure relief valve, exhaust shut-off valve, and pressure sensor. The low-pressure relief valve is used to release excess hydrogen through the low-pressure exhaust line when the pressure reducing valve malfunctions and causes overpressure at the outlet. The exhaust shut-off valve is used to actively release hydrogen from the downstream pipeline of the cylinder valve during gas replacement, hydrogen system maintenance, and repair.

[0007] In hydrogen storage modules, cylinder valves typically integrate functional components such as thermal fusion locks (TPRD), manual shut-off valves, solenoid valves, overflow valves, pressure sensors, and temperature sensors, playing a crucial role in the safe use of gas cylinders.

[0008] However, with the widespread use of hydrogen fuel cell vehicles, the appearance and models of these vehicles have changed to adapt to market demands. As a result, the hydrogen storage module needs to be modified for different models based on the available space during installation. Since there are many integrated components in the cylinder valve, its temperature sensor assembly and solenoid valve assembly require external wiring connections, which can easily lead to tangled wires. Utility Model Content

[0009] This application provides an easy-to-install cylinder valve and a gas supply system using it, which solves the problem of numerous wires and tangled wiring during cylinder valve installation.

[0010] The technical solution adopted in this application is as follows:

[0011] A cylinder valve that is easy to install is sealed to a gas cylinder. The cylinder valve is located at the cylinder opening and includes a lower housing inside the cylinder opening and an upper housing exposed outside the cylinder opening. The upper and lower housings have multiple channels. Each channel of the upper housing is equipped with one of a main valve assembly, a shut-off valve assembly, a solenoid valve assembly, or a TPRD assembly. Each channel of the lower housing is equipped with one of an overflow valve assembly, a temperature sensor assembly, or a one-way valve assembly. The channel equipped with the temperature sensor assembly is connected to the channel equipped with the solenoid valve assembly. The temperature sensor assembly includes a connecting line that connects to the solenoid valve assembly along the channel.

[0012] In a preferred embodiment of a bottle valve that is easy to install, the channel includes a first channel with a solenoid valve assembly and a second channel with a temperature sensor assembly. The second channel extends into the first channel, and the upper housing has a third channel connecting the first channel and the second channel. A connecting pipeline extends into the first channel through the third channel.

[0013] In a preferred embodiment of a bottle valve that is easy to install, the second channel extends upward from the lower housing to the upper housing, and the end of the third channel is connected to the end of the second channel.

[0014] In a preferred embodiment of a bottle valve that is easy to install, the other end of the third channel is provided with an open portion, which connects to the first channel.

[0015] In a preferred embodiment of a bottle valve that is easy to install, the wall of the third channel has an opening on the side close to the first channel so that the third channel is connected to the first channel, and the opening in the wall forms an open portion.

[0016] In a preferred implementation of a bottle valve that is easy to install, the inner diameter of the third channel is not less than the inner diameter of the second channel.

[0017] In a preferred implementation of a bottle valve that is easy to install, the inner diameter of the third channel is not greater than the inner diameter of the first channel.

[0018] In a preferred embodiment of a bottle valve that is easy to install, two channels for a main valve assembly and a shut-off valve assembly are coaxially arranged in the upper housing, and / or two channels for a TPRD assembly and a solenoid valve assembly are coaxially arranged in the upper housing.

[0019] In a preferred embodiment of a bottle valve that is easy to install, a clearance area is provided between the main valve assembly or shut-off valve assembly and the solenoid valve assembly, and the third channel is located in the clearance area.

[0020] It also includes a gas supply system for use in hydrogen fuel cell vehicles. The gas supply system includes a hydrogen refueling module, a pressure regulating module, and a hydrogen storage module. The hydrogen storage module includes a gas cylinder, a gas cylinder support, and connecting pipelines. The gas cylinder is equipped with a cylinder valve as described above at its opening.

[0021] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0022] (1) The solution proposed in this application provides a guarantee for the safe and stable use of gas cylinders by integrating multiple valve body components, such as shut-off valve components, TPRD components, and solenoid valve components. By connecting the channel with the temperature sensor component to the channel with the solenoid valve component, the connecting lines of the two components that need to be connected to the vehicle end are merged into the same channel, that is, merged into the channel with the solenoid valve component. Only one outlet is needed, avoiding the mess of exposed wiring. The wiring can be connected from one outlet, which is conducive to the convenient adjustment of the installation angle and installation position according to the vehicle model, and facilitates the installation of the gas cylinder valve.

[0023] (2) By setting a third channel to connect the first channel and the second channel, the connecting pipeline of the temperature sensor assembly is connected to the first channel along the third channel. The connecting pipeline is guided by the third channel so that it can enter the first channel along a predetermined route, avoiding internal wiring chaos and facilitating isolation and protection between the connecting pipeline and other components.

[0024] (3) By connecting the second channel of the upper housing, the connecting pipeline of the temperature sensor assembly can directly enter the third channel located in the upper housing. Since the end of the second channel is connected to the end of the third channel, the connecting pipeline directly enters the third channel at the end, which helps to shorten the laying path of the connecting pipeline, reduce the bending of the connecting pipeline, and reduce the installation difficulty.

[0025] (4) By setting an opening in the third channel, the connecting line of the temperature sensor enters the first channel through the opening and is connected to the solenoid valve assembly in the first channel. The line of the solenoid valve assembly extends to the outside of the bottle valve together for external line connection.

[0026] (5) By forming an opening in the side wall of the third channel, the side wall opening can be directly connected to the end of the adjacent third channel, that is, the end of the third channel is close to the first channel, thereby expanding the connection diameter between the third channel and the first channel. On the one hand, the connecting pipe of the temperature sensor can be directly extended from the opening and connected to the solenoid valve assembly without additional bending, which helps to further avoid wear of the connecting pipe. On the other hand, due to the expansion of the connection diameter, it is convenient to realize the connection operation between the connecting pipe and the solenoid valve assembly in the bottle valve, reducing the assembly difficulty.

[0027] (6) By limiting the inner diameter of the third channel, the inner diameter of the third channel is not less than the inner diameter of the second channel, which is conducive to the smooth entry of the connecting pipeline in the second channel into the third channel; setting the inner diameter of the third channel to be no greater than the inner diameter of the first channel is conducive to ensuring that the connecting pipeline enters the first channel directly from the third channel, avoiding the connecting pipeline from taking a detour, and is conducive to realizing the rapid and stable connection of the connecting pipeline and the solenoid valve assembly.

[0028] (7) This application arranges the main valve assembly and the shut-off valve assembly, as well as the TPRD assembly and the solenoid valve assembly, coaxially in the upper shell of the bottle valve. This results in a reasonable layout of the components within the bottle valve, ensuring that the components do not interfere with each other and facilitating assembly by workers, avoiding assembly confusion and reducing installation difficulty. The third channel is placed in the clearance area between the two components. The third channel does not occupy the assembly space of other components and does not cause assembly interference to other components. At the same time, it is beneficial to the processing and setting of the third channel. Attached Figure Description

[0045] This application provides a bottle valve that is easy to install, such as...Figures 1 to 6 As shown, the cylinder valve 1 is sealed to the gas cylinder. The cylinder valve 1 is provided at the cylinder opening. The cylinder valve 1 includes a lower housing 200 located inside the cylinder opening and an upper housing 100 exposed outside the cylinder opening. The upper housing 100 and the lower housing 200 are provided with multiple channels. Each channel of the upper housing 100 is provided with one of the following: a main valve assembly 110, a shut-off valve assembly 120, a solenoid valve assembly 130, or a TPRD assembly 140. Each channel of the lower housing 200 is provided with one of the following: an overflow valve assembly 220, a temperature sensor assembly 210, or a one-way valve assembly 230. The channel with the temperature sensor assembly 210 is connected to the channel with the solenoid valve assembly 130. The temperature sensor assembly 210 includes a connecting line, which is connected to the solenoid valve assembly 130 along the channel.

[0046] This application solution integrates multiple valve body components 140, such as a shut-off valve component 120, a TPRD component 140, and a solenoid valve component 130, into the cylinder valve 1, ensuring the safe and stable use of the gas cylinder. By connecting the channel equipped with the temperature sensor component 210 to the channel equipped with the solenoid valve component 130, the connecting lines of the two components 140 that need to be connected to the vehicle end are merged into the same channel, that is, merged into the channel equipped with the solenoid valve component 130. Only one outlet is needed, avoiding the mess of exposed wiring. The wiring can be connected from a single outlet, which is conducive to convenient adjustment of the installation angle and installation position according to the vehicle model, and facilitates the installation of the cylinder valve 1.

[0047] In one embodiment, the channel includes a first channel 150 with a solenoid valve assembly 130 and a second channel 240 with a temperature sensor assembly 210. The second channel 240 extends into the first channel 150, and the upper housing 100 has a third channel 160 that connects the first channel 150 and the second channel 240. A connecting line extends into the first channel 150 through the third channel 160.

[0048] By setting a third channel 160 to connect the first channel 150 and the second channel 240, the connecting line of the temperature sensor assembly 210 is connected to the first channel 150 along the third channel 160. The third channel 160 guides the connecting line so that it can enter the first channel 150 along a predetermined route, avoiding internal wiring tangles and facilitating isolation and protection between the connecting line and other components 140.

[0049] As one implementation method in this embodiment, the second channel 240 extends upward from the lower housing 200 to connect with the upper housing 100, and the end of the third channel 160 is connected to the end of the second channel 240.

[0050] By connecting the second channel 240 of the upper housing 100, the connecting pipeline of the temperature sensor assembly 210 can directly enter the third channel 160 located in the upper housing 100. Since the end of the second channel 240 is connected to the end of the third channel 160, the connecting pipeline directly enters the third channel 160 at the end, which helps to shorten the laying path of the connecting pipeline, reduce the bending of the connecting pipeline, and reduce the installation difficulty.

[0051] Preferably, the other end of the third channel 160 is provided with an opening 161, which is connected to the first channel 150.

[0052] By providing an opening 161 in the third channel 160, the connecting line of the temperature sensor enters the first channel 150 through the opening 161, thereby connecting to the solenoid valve assembly 130 in the first channel 150. The line of the solenoid valve assembly 130 extends to the outside of the bottle valve 1 together with the line of the solenoid valve assembly 130 for external wiring connection.

[0053] In a preferred embodiment, the third channel 160 has a wall opening on the side near the first channel 150 so that the third channel 160 connects to the first channel 150, and the wall opening forms an opening 161.

[0054] By forming an opening 161 in the side wall of the third channel 160, which can be directly connected to the end of the adjacent third channel 160, i.e. the end of the third channel 160 close to the first channel 150, the connection diameter between the third channel 160 and the first channel 150 is enlarged. On the one hand, the connecting line of the temperature sensor can extend directly from the opening 161 to connect with the solenoid valve assembly 130 without additional bending, which helps to further avoid wear of the connecting line. On the other hand, due to the enlarged connection diameter, it is easier to connect the connecting line to the solenoid valve assembly 130 inside the bottle valve 1, reducing the assembly difficulty.

[0055] In a preferred embodiment, the inner diameter of the third channel 160 is not less than the inner diameter of the second channel 240.

[0056] In addition, the inner diameter of the third channel 160 can be set to be no greater than the inner diameter of the first channel 150.

[0057] By limiting the inner diameter of the third channel 160, which is not less than the inner diameter of the second channel 240, it is beneficial for the connecting pipeline in the second channel 240 to smoothly enter the third channel 160. Setting the inner diameter of the third channel 160 to be no greater than the inner diameter of the first channel 150 helps to ensure that the connecting pipeline enters the first channel 150 directly from the third channel 160, avoiding detours in the connecting pipeline and facilitating a fast and stable connection between the connecting pipeline and the solenoid valve assembly 130.

[0058] In one embodiment, two channels of a main valve assembly 110 and a shut-off valve assembly 120 are coaxially arranged in the upper housing 100, and / or two channels of a TPRD assembly 140 and a solenoid valve assembly 130 are coaxially arranged in the upper housing 100.

[0059] Preferably, the two channels of the main valve assembly 110 and the shut-off valve assembly 120 are coaxially arranged in the upper housing 100. At the same time, the two channels of the TPRD assembly 140 and the solenoid valve assembly 130 are coaxially arranged in the upper housing 100, which reasonably optimizes the layout of the internal structure of the bottle valve and avoids assembly or application interference between the components.

[0060] Furthermore, a clearance area is provided between the main valve assembly 110 or the shut-off valve assembly 120 and the solenoid valve assembly 130, and the third channel 160 is located in the clearance area.

[0061] This application arranges the main valve assembly 110 and the shut-off valve assembly 120 coaxially within the upper housing 100 of the bottle valve 1, and the TPRD assembly 140 and the solenoid valve assembly 130 coaxially. This results in a reasonable layout of the components 140 within the bottle valve 1, ensuring that each component 140 does not interfere with the others, facilitating assembly by workers, avoiding assembly confusion, and reducing installation difficulty. The third channel 160 is positioned in the clearance area between two components 140. The third channel 160 does not occupy the assembly space of other components 140, does not cause assembly interference to other components 140, and is also beneficial for the processing and setting of the third channel 160.

[0062] The present application also includes a gas supply system for use in a hydrogen fuel cell vehicle. The gas supply system includes a hydrogen refueling module, a pressure regulating module, and a hydrogen storage module. The hydrogen storage module includes a gas cylinder, a gas cylinder support, and connecting pipelines. The gas cylinder is equipped with a cylinder valve 1 as described above at its cylinder opening.

[0063] Understandably, hydrogen fuel cell vehicles typically have a hydrogen storage module, a hydrogen refueling module, and a pressure regulating module. The hydrogen storage module includes high-pressure composite gas cylinders, gas cylinder supports, and connecting pipelines, etc. Each cylinder opening is equipped with a cylinder valve 1, and the gas cylinders are connected in parallel through pipelines.

[0064] The hydrogen refueling module includes a hydrogen refueling port and a high-pressure gauge. The hydrogen refueling port integrates functional components such as a hydrogen nozzle, filter, and one-way valve. The module can also integrate a high-pressure exhaust valve to facilitate gas replacement within the cylinder and to actively release high-pressure hydrogen from the cylinder during vehicle maintenance and repair.

[0065] The pressure regulating module (combination valve) is highly integrated and powerful, significantly simplifying hydrogen systems. The combination valve internally includes functional components such as a filter, pressure reducing valve, low-pressure relief valve, exhaust shut-off valve, and pressure sensor. The low-pressure relief valve is used to release excess hydrogen through the low-pressure exhaust line when the pressure reducing valve malfunctions and causes overpressure at the outlet. The exhaust shut-off valve is used to actively release hydrogen from the downstream pipeline of cylinder valve 1 during gas replacement, hydrogen system maintenance, and repair.
