[0032] The embodiment of the present application provides a valve assembly, see Figure 1 The valve assembly includes a valve block body 10 and a switching module.

[0033] The valve block is a key component of the integrated pipeline system. It can be used as a transition block for the distribution, collection and conversion of pipelines, or as a basic block for installing plate valves, cartridge valves, plug-in sensors, pipe joints, accessories and other components. It has an external interface on it, and its interior has flow channels connecting various external interfaces or components. Each flow channel achieves correct communication according to the designed principle. It is both a carrier for other components and a channel body for their flow channels to communicate. The shape of the valve block 10 provided in the embodiment of the present application can be a hexahedron such as a cuboid, a cube, etc., or a block of other shapes, such as an L-shaped block. The material of the valve block can be made of metal or non-metallic material, for example, it can be made of aluminum alloy, copper alloy, iron-based material, hard plastic, hard resin or epoxy resin material. Of course, other materials can also be used to make the valve block according to actual needs, and the embodiment of the present application does not limit this.

[0034] The adapter module can be of various types and can be used to achieve different functions. For example, the adapter module can be used to provide fluid flow, or the adapter module can be used to detect fluid parameters in the flow channel 11, or the adapter module can take into account both functions and can be used to provide fluid flow and detect fluid parameters in the flow channel 11 at the same time. The adapter module can include various types of sensors, valve bodies, pipeline components, etc., so as to achieve functions such as providing fluid flow and detecting fluid parameters in the flow channel 11. Figure 5 , Figure 5 As an embodiment of the adapter module, the functional element 40 can be used to connect to a water pipe, so that water can enter the flow channel 11 through the water pipe, the functional element 40 , the second opening 31 , and the first opening 13 .

[0035] The functional element 40 is connected to the adapter 30, and the functional element and the adapter 30 can be detachably connected, such as screw connection, clamp connection, etc. The functional element and the adapter 30 can also be non-detachably connected, such as integral molding, welding, etc. The material of the adapter module can be made of metal or non-metallic material, for example, it can be made of aluminum alloy, copper alloy, iron-based material, hard plastic, hard resin or epoxy resin material. Of course, the adapter module can also be made of other materials according to actual needs, and the embodiment of the present application is not limited to this.

[0036] In a complex integrated piping system, such as an integrated piping system of a hydrogen fuel cell system, a large number of different components are usually included. Different components usually have different requirements for the size of the mounting hole, the size of the flow channel hole, the sealing structure, the insertion depth, the connection screw hole, the positioning pin hole, etc. In order to integrate the combination of several different components and install them on different surfaces of the same valve block, it is necessary to customize and process different mounting structures on different surfaces of the valve block to install different types of components. This method has many problems: First, the function of the valve block is fixed and cannot be adapted to other component combinations. The versatility and scalability of the valve block are poor and cannot be adapted to different types of components. Second, due to the large number of component types and component combination types, if the traditional method of customizing the valve block is used, it will result in a wide variety of valve block configurations that need to be designed, a long design cycle, and low efficiency. Third, the processing of the customized valve block requires frequent mold changes, which is not conducive to mass production, a long processing cycle, and an overall cost increase.

[0037] The adapter module and the valve block 10 provided in the embodiment of the present application are detachably connected, for example, the adapter module and the valve block 10 can be screwed, clamped, etc. In this way, different adapter modules can be installed at different positions on the valve block 10, so that the valve assembly has multiple functions. For example, when the adapter module with the first function is installed at the first position on the valve block 10, the integrated pipeline system can have the first function; when the adapter module with the second function is installed at the first position on the valve block 10, the integrated pipeline system can have the second function. It is easy to understand that when people have different requirements for the functions of the integrated pipeline system in different scenarios, it is only necessary to remove the original adapter module from the valve block 10 and install the adapter module with the required function on the valve block 10. The valve block 10 has good versatility, and there is no need to customize the valve block so that the integrated pipeline system has different or multiple functions, which reduces the difficulty and cost of processing, is conducive to batch manufacturing, and has a short design cycle and processing cycle, and high efficiency.

[0038] Please combine Figure 1In the embodiment of the present application, the valve block body 10 is provided with a flow channel 11 for fluid flow, and the fluid may be: a liquid, such as water, oil. The fluid may also be a gas, such as air, hydrogen, etc. The cross-section of the flow channel 11 may be circular or polygonal. The number and position of the flow channels 11 may be configured according to actual needs, but the flow channel 11 must have at least two outlets to facilitate the fluid to flow into or out of the valve block body 10. The flow channel 11 may be configured to penetrate the valve block body 10, or may be configured not to penetrate the valve block body 10.

[0039] The valve block body 10 may be a rectangular parallelepiped structure. In some embodiments, a straight-through flow channel may be provided in only one or more directions of the length direction, width direction, and height direction of the valve block body 10. For example, a first straight-through flow channel with a circular cross section and penetrating the valve block body 10 may be provided in the length direction of the valve block body 10, two second straight-through flow channels with a circular cross section and penetrating the valve block body 10 may be provided in the width direction of the valve block body 10, and two third straight-through flow channels with a circular cross section and penetrating the valve block body 10 may be provided in the height direction of the valve block body 10. In this way, a total of five flow channels may be provided in the valve block body 10.

[0040] Please combine Figure 1 , Figure 2 as well as Figure 3 , a first opening 13 is provided on the surface of the valve block body, and the first opening 13 is connected to the flow channel 11. The adapter module includes an adapter 30 and a functional element 40, the adapter 30 is detachably mounted on the surface of the valve block body 10, the adapter 30 is provided with a second opening 31, and the second opening 31 is used to connect to the first opening 13, and the adapter 30 is installed with a functional element 40 on the side away from the valve block body 10, and the functional element 40 is used to provide fluid flow or to detect fluid parameters in the flow channel 11. Among them, when the functional element 40 is used to provide fluid flow, the functional element 40 may include various valve bodies, pipeline structures, etc. When the functional element 40 detects the flow channel 11 or the parameters of the fluid in the flow channel 11, the functional element 40 may include various types of sensors, such as temperature sensors, pressure sensors, gas concentration sensors, temperature and pressure integrated sensors, ion concentration sensors, conductivity sensors, flow sensors, etc., so that temperature, pressure, gas concentration, ion concentration, conductivity, etc. can be detected. Thereby, the functional element 40 can be arranged relative to the flow channel 11 through the second opening 31 and the first opening 13, and then fluid exchange can be carried out with the flow channel 11 through the functional element 40, such as inputting fluid into the flow channel 11, or draining the fluid in the flow channel 11; in addition, the parameters of the flow channel 11 or the fluid in the flow channel 11 can also be detected through the functional element 40.

[0041] In some embodiments, the switching module has multiple Figure 1 and Figure 2It can be seen that a plurality of adapter modules are installed around the valve block body 10. For ease of description, the plurality of adapter modules are defined to include a first adapter module 21 and a second adapter module 23. The functional elements of the first adapter module 21 and the functional elements of the second adapter module 23 may be different. For example, the functional elements of the first adapter module 21 may be used to control fluid delivery, and the functional elements of the second adapter module 23 may be used to detect fluid pressure; the functional elements of the first adapter module 21 and the functional elements of the second adapter module 23 may be the same. For example, the functional elements of the first adapter module 21 may be used to control fluid delivery, and the functional elements of the second adapter module 23 may be used for fluid delivery, which can be configured according to actual needs.

[0042] Specifically, please combine Figure 2 The first adapter module 21 may include a first adapter 301 and a first functional element 401, and the second adapter module 23 may include a second adapter 303 and a second functional element 403, wherein the first adapter 301 and the second adapter 303 may have the same general shape, as shown in FIG. Figure 2 , the appearance of the first adapter 301 and the second adapter 303 are both roughly hexahedrons. Of course, the appearance of the first adapter 301 and the second adapter 303 can also be set to other shapes, such as a cylinder, etc., which is not limited in the embodiments of the present application. In this way, the first adapter 301 and the second adapter 303 can be conveniently stacked for easy storage and transportation. In a specific embodiment, the second functional element 403 can be used to install a valve body, such as a one-way valve. The first adapter module 21 can also include a third functional element 405 and a fourth functional element 407. The third functional element 405 can be used to install a pipeline; the fourth functional element 407 can be used to install a ball valve.

[0043] The first adapter 301 and the second adapter 303 can be connected to the valve block 10 in the same manner, for example, see Figure 2 The first adapter 301 and the second adapter 303 are both provided with openings for connecting to the valve block 10 on their circumferential sides. The positions of these openings on the first adapter 301 and the second adapter 303 can be the same, which is convenient for processing, improves processing efficiency, and reduces processing costs. The difference between the first adapter 301 and the second adapter 303 can only be the shape and number of the openings provided for installing functional elements, which is convenient for installing different types of functional elements. In this way, the first adapter 301 and the second adapter 303 can be installed on the valve block 10 in a substantially similar manner.

[0044] The valve block body 10 has a first state and a second state. In the first state, the first adapter module 21 is installed on the surface of the valve block body 10; in the second state, the second adapter module 23 is installed on the surface of the valve block body 10. In this way, when the valve block body 10 is required to perform different functions in different scenarios, it is only necessary to replace the adapter module on the surface of the valve block body 10. For example, the surface of the original valve block body 10 is installed with the first adapter module 21, and the first adapter module 21 may include a first adapter 301 and a first functional element 401, so that the original valve block body 10 can perform the first function. Later, if you want the valve block body 10 to have a second function, you only need to remove the first adapter module 21 and the first functional element 401 from the valve block body 10, and install the second adapter module 23 with the second function on the surface of the valve block body 10.

[0045] The second adapter module 23 may include a second adapter 303 and a second functional element 403. The second functional element 403 may be installed on the second adapter 303 in advance to form the second adapter module 23, and then the second adapter 303 may be installed on the valve block 10 to achieve the connection between the second adapter module 23 and the valve block 10. Alternatively, the second adapter 303 may be installed on the valve block 10 first, and then the second functional element 403 may be installed on the side of the second adapter 303 away from the valve block 10. Thus, the valve block 10 can perform the second function. The second adapter 303 may be installed on the valve block 10 in the same manner as the first adapter 301 is installed on the valve block 10.

[0046] Please combine Figure 1 , Figure 2 as well as Figure 4 The first opening 13 is used to facilitate the installation of the adapter module, so that the valve block body can perform corresponding functions in combination with the functional elements of the adapter module, such as providing fluid flow or detecting fluid parameters in the flow channel 11. In some embodiments, there can be multiple adapter modules, that is, multiple adapter modules are installed on a valve block body, so that a valve block body has multiple functions. Specifically, multiple first openings 13 can be opened on the surface of the valve block body, and the multiple adapter modules are configured to correspond to the first openings 13 one by one.

[0047] In some embodiments, the surface of the valve block body 10 may include multiple sub-surfaces facing different directions. For example, the specific shape of the valve block body 10 may be a hexahedron, such as a cuboid, a cube, etc., and the material may be an alloy, such as an aluminum alloy, a titanium alloy, etc. In some specific implementations, at least two sub-surfaces of the surface of the valve block body 10 may be provided with a first opening; or, at least one sub-surface may be provided with two first openings.

[0048] In some embodiments, the functional elements of the plurality of adapter modules are at least one of a connecting plate valve, a cartridge valve, an insert sensor, and a pipe joint, so as to cooperate with the valve block body to facilitate the function of providing fluid flow or detecting fluid parameters in the flow channel 11.

[0049] Please combine Figure 1 , Figure 2 In some embodiments, the valve assembly further includes an elastic member 50, which is sandwiched between the valve block 10 and the adapter 30 and is located around the first opening 13. The elastic member 50 is mainly used for sealing, so that the valve block 10 and the adapter 30 can be more tightly connected to prevent leakage of the fluid in the flow channel. The material of the elastic member 50 should be elastic, for example, it can be a soft rubber material such as rubber silicone, or it can be a material such as plastic.

[0050] Furthermore, in order to achieve a better sealing effect, the elastic member 50 may be an O-shaped sealing ring or a polygonal sealing ring, and the elastic member 50 is coaxially arranged with the first opening 13. The cross section of the elastic member 50 may be circular or polygonal.

[0051] Please combine Figure 1 , Figure 2 as well as Figure 4 Furthermore, in order to better install the elastic member 50 and prevent the elastic member 50 from moving and affecting the sealing effect, a first groove 15 is opened on the surface of the valve block body 10, which is used to form a first limiting cavity with the adapter, and the elastic member is clamped in the first limiting cavity; wherein the first limiting cavity can be coaxially arranged with the flow channel 11, and the cross-section of the first limiting cavity can be a circular ring or a polygon.

[0052] Alternatively, a second groove may be provided in the adapter to form a second limiting cavity with the surface of the valve block, and the elastic member may be clamped in the second limiting cavity; wherein the second limiting cavity may be coaxially arranged with the flow channel 11, and the cross-section of the second limiting cavity may be circular or polygonal.

[0053] Alternatively, a first groove may be provided on the surface of the valve block, and a second groove may be provided on the side of the adapter facing the valve block, and the first groove and the second groove may cooperate to clamp the elastic member. The first limiting cavity may be coaxially arranged with the flow channel 11, and the second limiting cavity may be coaxially arranged with the flow channel 11. The cross section of the first limiting cavity may be circular or polygonal. The cross section of the second limiting cavity may be circular or polygonal.

[0054] In some embodiments, the valve assembly further includes a connector (not shown in the figure), through which the valve block body 10 and the adapter 30 of the adapter module can be connected. A first mounting hole 33 is provided on the periphery of the adapter, and a second mounting hole 16 matching the first mounting hole 33 is provided on the valve block body. The connector is sequentially inserted through the first mounting hole 33 and the second mounting hole 16, and is detachably connected to the valve block body 10. The connector and the valve block body can be screwed, in which case the second mounting hole 16 is a threaded hole, and threads are provided on the periphery of the connector.

[0055] In some embodiments, there are multiple first mounting holes 33, and the multiple first mounting holes 33 are evenly arranged around the second opening 31. There are multiple second mounting holes 16, and the first mounting holes 33 match the second mounting holes 16 one by one. Thereby, the valve block body 10 and the adapter 30 of the adapter module are tightly connected. In some embodiments, the number of the first mounting holes 33 can be four, and the number of the second mounting holes 16 can be four. The number and position of the first mounting holes 33 can correspond to the number and position of the second mounting holes 16, which is convenient for assembly. During installation, the elastic member can be placed between the valve block body 10 and the adapter 30 first, and then the adapter 30 and the valve block body 10 are connected and fixed using connecting members such as screws and bolts. The elastic member 50 is squeezed by the adapter 30 and the valve block body 10 and is in a contracted state, thereby achieving a sealing effect.

[0056] The four first mounting holes 33 are evenly arranged in a central symmetric manner relative to the central axis of the flow channel. The extension direction of the first mounting hole 33 is parallel to the central axis of the flow channel. The four second mounting holes 16 are evenly arranged in a central symmetric manner relative to the central axis of the flow channel. The extension direction of the second mounting hole 16 is parallel to the central axis of the flow channel. The first mounting hole 33 can be an opening with an internal thread, or a common opening. The second mounting hole 16 can be an opening with an internal thread, or a common opening.

In the integrated pipeline, the valve block is universal, and by selecting different adapter modules and assembling the universal valve block into a valve assembly, it can adapt to different component combinations and expand installation requirements to achieve functional modularization.
