These systems are widely used in many fields such as petroleum, chemical industry, water treatment, pharmaceuticals, food processing, and aerospace. Their reliability and ease of maintenance are directly related to the safe operation and economic benefits of the entire system.

[0003] Traditional plug-in valve designs mostly rely on threaded assembly technology, which uses the tight engagement of internal and external threads to achieve the connection and fixation between valve components. Specifically, the main body of the valve is usually equipped with external threads, while the valve block or pipe connected to it has matching internal threads. The two are tightened against each other by rotation to achieve the purpose of sealing and fixing. However, this assembly method is time-consuming and labor-intensive, with low disassembly and assembly efficiency, and requires special tools for disassembly, which increases the workload for on-site maintenance personnel.

[0004] Therefore, based on some of the above prior art situations, the present application has been further designed and improved. Utility Model Content

[0023] Reference Figures 1 to 4 A quick-release plug-in valve is plug-in-connected with a valve block, comprising a valve body 10 and a valve sleeve 20 sleeved on the valve body 10, wherein the valve sleeve 20 is threadedly connected to the valve block. The valve body 10 is provided with a first sealing groove 11 below the valve sleeve 20, wherein a sealing ring 12 is assembled in the first sealing groove 11, wherein the sealing ring 12 abuts between the valve body 10 and the valve block to achieve sealing. A snap-fitting groove 21 is provided on the inner wall of the valve sleeve 20, wherein a locking groove 22 is provided at the bottom of the snap-fitting groove 21, wherein a locking head 15 is provided on the valve body 10, wherein the locking head 15 enters the locking groove 22 through the snap-fitting groove 21 to achieve locking and fixing of the valve body 10. During disassembly, the user only needs to twist the valve body 10 so that the locking head 15 is disengaged from the snap-fitting groove 21 to complete the disassembly of the valve body 10, thereby greatly improving the disassembly and assembly efficiency and meeting the user's requirements for high efficiency, reliability and easy maintenance.

[0024] In order to further improve the efficiency of disassembly and assembly of the valve body 10, the engaging slide groove 21 includes a smooth section 23 and an inclined slide section 24, the locking groove 22 is located at one end of the smooth section 23, one end of the inclined slide section 24 is connected to the other end of the smooth section 23, and the other end of the inclined slide section 24 is connected to the upper surface of the valve sleeve 20 and is opened. During disassembly, the locking head 15 is disengaged from the locking groove 22, and is disengaged from the valve sleeve 20 through the smooth section 23 and the inclined slide section 24, thereby realizing the disengagement of the valve body 10 and the valve sleeve 20. In particular, when the locking head 15 passes through the inclined slide section 24, the valve body 10 will be driven to rise a certain distance, so as to avoid the problem that the valve body 10 is stuck on the valve sleeve 20 after long-term use, making it difficult to pull out the valve body 10.

[0025] Furthermore, the rotation direction of the valve body 10 when the valve body 10 is locked is the same as the rotation direction of the valve sleeve 20 when the valve sleeve 20 is assembled on the valve block. The valve body 10 is provided with a hexagonal portion 13 for twisting the valve body 10, and the design of the hexagonal portion 13 is convenient for twisting with a tool. During installation, the valve body 10 and the valve sleeve 20 can be regarded as a whole, and the user can drive the valve sleeve 20 to rotate by twisting the valve body 10, making the installation of the plug valve faster and more convenient.

[0026] In the present utility model, in order to ensure the sealing performance of the plug valve, the valve body 10 is provided with an inverted stepped surface 14, and the valve sleeve 20 is provided with a step groove 25 corresponding to the step surface 14. The step groove 25 is equipped with an O-ring 27, and the O-ring 27 abuts between the step groove 25 and the step surface 14. The O-ring 27 can further enhance the sealing effect, and through the stepped structural design, the user can use the rebound effect of the O-ring 27 when removing the valve body 10 from the valve sleeve 20, making the removal more labor-saving. The bottom of the valve sleeve 20 is provided with a second sealing groove 26, and the second sealing groove 26 cooperates with the first sealing groove 11 to form a sealing groove for assembling the sealing ring 12. This design provides a more precise assembly position for the sealing ring 12, enhances the reliability of the seal, and reduces potential failures caused by poor sealing.

[0027] It should be noted that the valve body 10 structure in the accompanying drawings is for display purposes only and does not limit the type of plug-in valve of the present application. Its specific design can be adjusted and optimized in a variety of ways according to actual application scenarios and functional requirements. For example, according to the characteristics of the fluid medium (such as temperature, pressure, corrosiveness, etc.), the material of the valve body 10 can be selected from stainless steel, copper alloy, engineering plastics or other corrosion-resistant materials to ensure long-term reliability and safety. In addition, the valve core structure can be designed to be spherical, butterfly, needle or sleeve-shaped, etc., to adapt to different flow control accuracy and switching requirements. For application scenarios that require precise adjustment of fluid flow, a valve core design with fine adjustment function can be used, combined with a precise drive mechanism to achieve fine control of the flow.

[0028] In response to the needs of automated control, plug-in valves can integrate a variety of control methods, including electromagnetic control, pneumatic control, hydraulic control and intelligent electronic control, to achieve remote control and automatic adjustment functions. To enhance the compatibility and scalability of the system, the interface standard should follow the general industry standards, such as ISO, DIN or ANSI, so as to facilitate rapid docking and integration with other equipment.

[0029] In summary, although the accompanying drawings show a specific valve body 10 structure, the plug-in valve design of the present application is highly flexible and customizable, and can meet the specific requirements of different industries and fields through diversified structure and material selection, precise manufacturing process and intelligent functional integration, reflecting the foresight and practicality of the technology.
