Description

Technical Field

[0001] This utility model relates to the field of fluid valve technology, specifically to a fluid valve with an easy-to-replace valve core. Background Technology

[0002] Fluid valves are mechanical devices used to control the flow of fluids (liquids or gases). They play a vital role in pipeline systems to regulate the flow rate, pressure, and direction of fluids, thereby ensuring the safe, efficient, and reliable operation of the system. There are many types of fluid valves, including ball valves, gate valves, globe valves, butterfly valves, etc., each with its specific uses and performance characteristics.

[0003] After prolonged use, the internal valve core of existing fluid valves is easily damaged by the fluid. Current repair methods mostly involve directly removing and replacing the entire valve, which is not only cumbersome but may also cause unnecessary losses. To solve this problem, we propose a fluid valve design that facilitates valve core replacement. Utility Model Content

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1-5 As shown, in this embodiment, a fluid valve with an easily replaceable valve core includes a valve body 1. An inlet pipe 2 and an outlet pipe 3 are fixedly connected to both sides of the valve body 1. A partition 5 is fixedly connected between the inner walls of the valve body 1. A through hole 6 is provided inside the partition 5. An installation pipe 4 is fixedly connected to the top of the valve body 1. Side grooves 7 are provided on both sides of the inner wall of the installation pipe 4. A valve core body 14 is slidably connected between the inner walls of the installation pipe 4. Side plates 15 are fixedly connected to both sides of the valve core body 14. The outer sides of the side plates 15 are slidably connected to the inner walls of the side grooves 7. A locking assembly is provided on the outer side of the installation pipe 4 to fix the valve core body 14. The inner walls of the valve core body 14 are slidably connected. A threaded cylinder 17 is dynamically connected, a fixed rod 21 is fixedly connected to the bottom of the threaded cylinder 17, and a sealing block 22 is fixedly connected to the bottom end of the fixed rod 21. A threaded rod 20 is rotatably connected inside the valve core body 14, and a handle 23 is rotatably connected to the top of the valve core body 14. One end of the handle 23 extends into the interior of the valve core body 14 and is fixedly connected to the threaded rod 20. Keyways 18 are provided on both sides of the inner wall of the valve core body 14. Flat keys 19 are fixedly connected to both sides of the threaded cylinder 17. The outer side of the flat key 19 is slidably connected to the inner wall of the keyway 18. A sealing edge 16 is fixedly connected to one side of the valve core body 14. The inner side of the sealing edge 16 is in contact with the outer side of the mounting tube 4.

[0022] When using the fluid valve, fluid is introduced through the inlet pipe 2, and after entering the valve body 1, the fluid is discharged from the outlet pipe 3 through the through hole 6. When the valve needs to be closed, the handle 23 is turned, causing the threaded rod 20 to rotate inside the valve core body 14, so that the threaded cylinder 17 on the outside moves smoothly under the action of the key 18 of the flat key 19, thereby driving the fixed rod 21 at the bottom of the threaded cylinder 17 and the sealing block 22 to move simultaneously. The valve body 1 is closed by extending the sealing block 22 into the interior of the through hole 6.

[0023] When replacing the valve core body 14, the valve core body 14 is released by the locking component. Then, the staff will pull the valve core body 14 out of the installation tube 4, which will make it easier for the staff to clean and replace the valve core body 14.

[0024] like Figures 1-5 As shown, the locking assembly includes a locking box 8, which is fixedly connected to the outside of the mounting tube 4. A sliding plate 9 is slidably connected between the inner walls of the locking box 8. A locking block 10 is fixedly connected to one side of the sliding plate 9. A slot 24 is provided on one side of the side plate 15. One end of the locking block 10 extends into the slot 24. A spring 12 is fixedly connected between the sliding plate 9 and the inner wall of the locking box 8. A connecting rod 11 is fixedly connected to the side of the sliding plate 9 away from the locking block 10. One end of the connecting rod 11 extends to the outside of the locking box 8 and is fixedly connected to an adjusting block 13.

[0025] By pulling the adjusting block 13, the slide plate 9 moves under the action of the connecting rod 11, which in turn drives the locking block 10 to move synchronously, causing it to be pulled out of the slot 24. This process releases the lock on the valve core body 14, making it easier for the staff to replace the valve core body 14.

[0026] This utility model provides a fluid valve that facilitates valve core replacement. The specific working principle is as follows: When using the fluid valve, fluid is introduced through the inlet pipe 2, and after entering the valve body 1, the fluid is discharged from the outlet pipe 3 through the through hole 6. When the valve needs to be closed, the handle 23 is turned, causing the threaded rod 20 to rotate inside the valve core body 14. This causes the threaded cylinder 17 on its outer side to move smoothly under the action of the keyway 18 of the flat key 19, thereby driving the fixed rod 21 at the bottom of the threaded cylinder 17 and the sealing block 22 to move simultaneously. The valve body 1 is closed by extending the sealing block 22 into the through hole 6.

[0027] When replacing the valve core body 14, the operator pulls the adjusting block 13 to move the slide plate 9 under the action of the connecting rod 11, which in turn drives the locking block 10 to move synchronously, so that it is pulled out from the slot 24, thereby releasing the lock on the valve core body 14. Then the operator can pull the valve core body 14 out from the installation tube 4 for easy cleaning and replacement.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
