Description

Technical Field

[0001] This utility model relates to the field of valve core technology, and in particular to a highly adaptable split-type safety valve core. Background Technology

[0002] A safety valve is a special valve whose opening and closing elements are normally closed under the action of external force. When the pressure of the medium in the equipment or pipeline rises above the specified value, it prevents the pressure of the medium in the pipeline or equipment from exceeding the specified value by discharging the medium to the outside of the system.

[0003] Existing safety valves require bolts for assembly of the valve body and cover. During assembly, workers need to align the bolt holes on the valve body and cover before using bolts to secure them. This requires workers to ensure the stability of the valve body and cover during installation to prevent bolt hole misalignment. The installation process is cumbersome, inefficient, and impractical. Furthermore, prolonged use of the safety valve can cause changes in the spring's verticality and a decrease in spring force, affecting the valve's performance and impacting personal safety and equipment operation.

[0009] Furthermore, a set of second bolts is threaded through the valve body, and the set of second bolts is threadedly connected to the valve seat.

[0010] Furthermore, a pull ring is fixedly connected to the pull rod, and the pull ring is provided with anti-slip texture.

[0011] Furthermore, a limiting block is fixedly connected to the side wall of the adjusting block, a limiting groove is opened on the side wall of the valve cover, and the limiting block is slidably connected in the limiting groove.

[0012] Furthermore, a limiting cylinder is fixedly connected to the upper end face of the valve cover, the valve stem slides through the connecting block and the adjusting block, one end of the valve stem is installed on the backwash plate, a lifting block is slidably connected inside the limiting cylinder, and the other end of the valve stem is fixedly connected to the lifting block.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. When installing the valve body and valve cover, the user inserts the fixing block on the valve cover into the fixing hole, and the locking block will automatically fix the fixing block. Then, the user uses the first bolt to fix the valve cover and valve body, which facilitates the user's assembly of the valve cover and valve body, improves the portability of the device assembly, and improves the installation efficiency.

[0015] 2. When the user rotates the handle, the second bevel gear starts to rotate, which in turn causes the first rotating gear on the connecting frame to rotate. The external threaded tube rises or falls, allowing the adjusting block to slide inside the valve cover, thus adjusting the extension and retraction of the spring frame. This adjusts the spring force of the spring frame, allowing the connecting block to adjust the support force on the valve stem, facilitating the regulation and control of the pressure inside the valve body and improving the practicality of the device.

[0024] The positioning and fixing assembly includes two fixing blocks 8 fixedly connected to the lower end face of the valve cover 6. The valve body 5 has two fixing ports, and the two fixing blocks 8 are respectively matched with the two fixing ports. The side wall of the valve body 5 is fixedly connected to the mounting block 9. The mounting block 9 has a sliding cavity 10. The inner wall of the sliding cavity 10 is fixedly connected to a set of telescopic springs 11. The sliding block is slidably connected to the sliding cavity 10 and is fixedly connected to the set of telescopic springs 11. The sliding block is fixedly connected to the sliding block and has a locking block 12. The locking block 12 slides through the mounting block 9 and the valve body 5. One of the fixing blocks 8 has a locking groove, and the locking block 12 matches the locking groove. The locking block 12 is wedge-shaped. The mounting block 9 has a pull rod that slides through it. One end of the pull rod is fixedly connected to the sliding block. The pull rod is fixedly connected to a pull ring 20. The pull ring 20 has anti-slip texture to facilitate the user to pull the pull rod and improve the portability of the device. The valve cover 6 has a set of first bolts 13 threaded through it. The set of first bolts 13 are all threadedly connected to the valve body 5.

[0025] The adjusting assembly includes a connecting frame 14 fixedly connected to the inner wall of the valve cover 6. A first rotating gear 15 is rotatably connected to the upper end face of the connecting frame 14. An externally threaded tube 16 is threaded through the first rotating gear 15 and slides through the valve cover 6. An adjusting block is slidably connected to the inner wall of the valve cover 6. The end of the spring frame 7 away from the connecting block is fixedly connected to the adjusting block. The externally threaded tube 16 is fixedly connected to the adjusting block. Two support blocks are fixedly connected to the side wall of the valve cover 6. A second rotating gear 17 is rotatably connected between the two support blocks. The first rotating gear 15 and the second rotating gear 17 mesh with each other. The upper end face of the valve cover 6 is fixed. A protective shell is connected, and a first bevel gear 18 and a second bevel gear are rotatably connected to the inner wall of the protective shell. A transmission rod rotatably passes through the valve cover 6, and the two ends of the transmission rod are respectively fixedly connected to the first bevel gear 18 and the second rotating gear 17. A handle 19 rotatably passes through the protective shell and is fixedly connected to the second bevel gear. A limit block is fixedly connected to the side wall of the adjusting block, and a limit groove is opened on the side wall of the valve cover 6. The limit block is slidably connected in the limit groove to limit the adjusting block, so that the adjusting block only performs lifting and lowering work in the valve cover 6, and avoids the external threaded tube 16 being subjected to the torque applied by the first rotating gear 15, which would cause the adjusting block to rotate.

[0026] The detailed working process of this utility model is as follows:

[0027] When assembling the valve body 5 and valve cover 6, the user first inserts the fixing block 8 on the valve cover 6 into the fixing hole on the valve body 5. One of the fixing blocks 8 will contact the locking block 12, causing the locking block 12 to be pushed. The telescopic spring 11 located in the sliding cavity 10 will contract, and the locking block 12 will temporarily contract into the sliding cavity 10. When the locking slot is aligned with the locking block 12, the telescopic spring 11 will automatically return to its original position, allowing the locking block 12 to automatically fix the fixing block 8. Subsequently, the user uses the first bolt 13 to fix the valve cover 6 and valve body 5. This facilitates the user's assembly of the valve cover 6 and valve body 5 using the first bolt 13, preventing misalignment of the valve cover 6 and valve body 5 during installation and improving the assembly efficiency of the device. The portability of the device improves installation efficiency. After assembly, the user can rotate the handle 19 to start the second bevel gear to rotate, the first bevel gear 18 inside the protective shell to rotate, the second rotating gear 17 inside the valve cover 6 to rotate, and the first rotating gear 15 on the connecting frame 14 to rotate. The external threaded tube 16 rises or falls, allowing the adjusting block to slide inside the valve cover 6, thereby adjusting the extension and retraction of the spring frame 7 and adjusting the elastic force of the spring frame 7. This allows for adjustment of the supporting force of the connecting block on the valve stem 4, facilitating the regulation and control of the pressure inside the valve body 5 and improving the practicality of the device.
