Detailed implementation mode

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Refer to Figures 1 to 2 , an embodiment provided by the present invention: an inserted flow control valve, including a valve tube 1, an inner part of the valve tube 1 is fixedly connected with a socket tube 2, an outer part of the socket tube 2 is slidably connected with a sliding assembly. The design of the sliding assembly usually includes multiple annular slide rails to ensure smooth sliding. Its outer material is mostly made of elastic materials such as polyurethane or rubber, with good oil resistance and wear resistance to improve the overall service life. An outer part of the sliding assembly is fixedly connected with a plurality of connecting columns 5. An outer part of the socket tube 2 is slidably connected with a plurality of expansion rings 6. An outer part of the plurality of connecting columns 5 is fixedly connected with a plurality of placing grooves 7, which effectively prevent locking parts or connecting parts from falling off during use. The placing groove 7 is in the shape of a groove and is specifically used for placing locking parts or connecting parts to ensure the stability of the connection. An outer part of the plurality of expansion rings 6 is provided with placing grooves 7. Its design provides a dedicated placement space for locking parts or connecting parts, thereby ensuring the stability and reliability of the connection. An outer part of the socket tube 2 is slidably connected with a plurality of expansion rings 6. The expansion ring 6 is usually annular and made of an elastic material, enabling it to slide freely within a certain range while maintaining good sealing performance. Both left and right sides of an outer part of the valve tube 1 are fixedly connected with limiting rings 9. The design of the limiting ring 9 is in an annular structure and is usually made of steel or aluminum alloy materials to enhance its connection degree. An annular groove 8 is opened in an outer part of the limiting ring 9. A sealing structure such as a sealing rubber ring can be placed inside the annular groove 8. The design of secondary sealing can better prevent leakage at the inlet.

[0031] Refer to Figures 3 to 4, the sliding component includes a sliding ring 3. A plurality of sliding grooves 4 are formed on the outer side of the socket pipe 2, and the sliding ring 3 slides inside the sliding grooves 4. The top of the valve pipe 1 is threadedly connected with a rotating column 10. The rotating column 10 penetrates through the top of the valve pipe 1. The design enables it to maintain stability during rotation and minimize vibration to the greatest extent. The bottom of the rotating column 10 is threadedly connected with a hollow pipe 11. The inner bottom wall of the hollow pipe 11 is provided with a blocking groove 12. The shape of the blocking groove 12 is a groove shape, which is used to block the unnecessary flow of liquid when the rotating column 10 rotates, increasing the precision control and stability during use. The left side inside the valve pipe 1 is threadedly connected with a spring 14. The outside of the spring 14 is fixedly connected with a joint column 13. The outside of the joint column 13 is fixedly connected with a connecting block 18. The connecting block 18 is designed as a square structure, having a large contact area to improve the connection stability. The outside of the joint column 13 is fixedly connected with a fixing block 15. The top of the fixing block 15 is detachably connected with a gasket 16. The gasket 16 is made of a high-density rubber material to provide good sealing performance, prevent liquid leakage and at the same time control the internal flow rate. The outside of the joint column 13 is fixedly connected with a blocking ring 17. The gasket 16 is located on the side close to the fixing block 15 and the blocking ring 17. The joint column 13 penetrates through the fixing block 15. The top of the rotating column 10 is fixedly connected with a joint block 19. The outside of the joint block 19 is fixedly connected with a handle 20. The outside of the handle 20 is fixedly connected with a sleeve handle 21.

[0032] Working principle: When the device is in use, the sealing rubber can be placed in the placement groove 7 and the annular groove 8. The valve pipe 1 is placed at the required target inlet. After insertion, by pushing the sliding ring 3, at this time, the sliding ring 3 will drive the forward sliding inside the sliding groove 4, and the connecting column 5 will push the placement groove 7 to the front end of the socket pipe 2. When pushing the sliding ring 3, the expanding ring 6 will expand inside the inlet. The sliding ring 3 will slide into the groove at the front end of the socket pipe 2 for fixation, preventing the sealing rubber ring placed inside the groove 7 from sealing the inlet through the expanding ring 6, so that the liquid flows into the inside of the socket pipe 2. The purpose is to increase the sealing performance at the interface. At the same time, one end of the limiting ring 9 will fit with the opening, and the annular groove 8 will seal the inlet again. The purpose is to prevent leakage during use and increase the use cost;

[0033] After placement, connect the limiting ring 9 at one end of the valve pipe 1 to the outlet to facilitate the use of the device. After the placement is completed, rotate the handle 20. The rotating column 10 will open or close the internal blocking groove 12, and its purpose is to facilitate the control of the flow rate. When the liquid starts to flow into the device from the inlet, the flowing liquid will squeeze the blocking ring 17, causing the spring 14 at the bottom of the joint column 13 to start compressing. The liquid will flow to the outlet through both sides of the fixed block 15 and the connecting block 18. At the same time, the handle 20 can be toggled to move the rotating column 10 closer to the internal blocking groove 12 to slow down the flow rate. On the contrary, when moving towards the outside of the valve pipe 1, the flow rate can be increased to facilitate control.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
