Description

Technical Field

[0001] This utility model relates to the field of valve body technology, and more specifically to a combined valve body. Background Technology

[0002] As a key component of fluid control systems, the valve body is widely used in various industrial fields such as hydraulics, pneumatics, chemical engineering, and energy. Traditional valve bodies often adopt an integral structure, integrating the flow channels, valve orifices, and interfaces into a single valve block through casting or machining. While this integrated design is compact, it has several limitations in practical applications: First, the manufacturing process of integral valve bodies is complex, requiring high casting precision and machining technology. Especially when the flow channel structure is complex or the number of valve holes is large, casting defects or machining errors are prone to occur, leading to low yield and increased costs. Second, if a part of the valve body is damaged or the flow channel configuration needs adjustment, the entire valve body often needs to be replaced, resulting in high maintenance costs, long cycles, and hindering rapid on-site maintenance. Furthermore, traditional valve bodies lack flexibility, making it difficult to adjust or expand according to actual operating conditions (such as the addition or removal of flow, pressure, or functional modules), thus limiting their applicability.

[0003] As industrial equipment evolves towards modularity, integration, and high reliability, existing integrated valve bodies are no longer sufficient to meet diverse and customized application needs. Therefore, there is an urgent need for a valve body solution that is structurally sound, easy to assemble and disassemble, flexibly combinable, and possesses excellent sealing performance to overcome the shortcomings of existing technologies. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a modular valve body. Through modular design and standardized connection structure, this modular valve body effectively solves the technical bottlenecks in manufacturing, maintenance, and functional expansion of traditional valve bodies.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A combined valve body includes a first valve block, a second valve block, and a connecting pipe. Both the first and second valve blocks have a main channel and several valve holes communicating with the main channel. The connecting pipe includes an end pipe and a connecting pipe, both having several communicating holes. One end of the end pipe has a limiting head, and the other end has a first connecting portion. Both ends of the connecting pipe have second connecting portions. The end pipe and the connecting pipe are connected and conductive through the first and second connecting portions. The end pipe and the connecting pipe extend into the main channels of the first and second valve blocks, respectively, and the several communicating holes of the end pipe and the connecting pipe correspond to several valve holes on the first and second valve blocks. The end of the connecting pipe away from the end pipe is connected to a sealing head through the second connecting portion. A splicing and fixing member is provided between the first and second valve blocks.

[0006] Furthermore, both the first and second connecting parts are provided with internal threads, and a double-threaded head connecting sleeve is provided between the end pipe and the connecting pipe. The double-threaded head connecting sleeve extends into the first connecting part of the end pipe and the second connecting part of the connecting pipe respectively to perform threaded connection.

[0007] Furthermore, dovetail grooves are provided on both sides of the first valve block and the second valve block. The connecting component includes a dovetail block and several bolts. Mounting holes are provided at both ends of the dovetail block, and the dovetail block extends into the dovetail grooves of the first valve block and the second valve block respectively. Threaded holes are provided in the dovetail grooves of the first valve block and the second valve block. Several bolts pass through the mounting holes at both ends of the dovetail block and extend into the threaded holes in the dovetail grooves of the first valve block and the second valve block for threaded connection.

[0008] Furthermore, the end cap is provided with a connecting post, the connecting post is provided with external threads, and the connecting post extends into the second connecting part of the connecting pipe for threaded connection.

[0009] Furthermore, a sealing sleeve is provided at the connection between the valve hole and the connecting hole.

[0010] Furthermore, the top block of the first valve block is provided with a polygonal positioning hole, and the limiting head is in the shape of a polygonal prism, and the limiting head extends into the polygonal positioning hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. High modularity and flexibility: Valve blocks (first valve block and second valve block) and pipes (end pipes and connecting pipes) can be manufactured, selected and replaced independently to adapt to different flow, pressure or functional requirements, reducing production costs and inventory pressure.

[0012] 2. Convenient installation and maintenance: The use of standardized interfaces such as threaded connections and dovetail groove fixation simplifies the assembly process and facilitates on-site installation, debugging and subsequent maintenance.

[0013] 3. Superior sealing performance: Through multiple sealing designs such as sealing sleeves and end caps, the valve body is reliably sealed under high pressure, high temperature or corrosive media, reducing the risk of leakage.

[0014] 4. Stable and durable structure: The dovetail groove and polygonal positioning structure enhance the mechanical stability between components, prevent misalignment or loosening, and improve the overall durability and safety of the structure.

[0015] This invention not only solves the problems of complex manufacturing and difficult maintenance of traditional integrated valve bodies, but also improves the performance and service life of the valve body by optimizing the connection and sealing structure. Attached Figure Description
