[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3This utility model provides an anti-rotation oil valve, including a valve body 3, which includes a valve body, a valve cover, a valve seat, a valve plate, and a valve stem 6. A shell 1 is welded to the top of the valve body 3, and the valve stem 6 passes through the shell 1. A groove 4 is provided on the top of the shell 1, and a slider 10 is slidably connected in the groove 4. The outer wall of the valve stem 6 is symmetrically provided with limiting grooves 5 that slide with the slider 10. Multiple slots 11 are evenly provided on the outer side of the slider 10. The inner wall of the groove 4 is fixed with bolts to insert blocks 12 that mate with the multiple slots 11. The bottom wall of the groove 4 is provided with a groove... The four connected grooves 13 have a fixed ring 9 welded to the bottom of the slider 10, which slides in conjunction with the groove 13. The housing 1 contains a pushing assembly that moves the fixed ring 9 upwards. The pushing assembly includes a first sliding groove 7 inside the housing 1 and connected to the groove 13. A wedge block 8 is slidably connected within the first sliding groove 7. One side of the wedge block 8 has an inclined surface that engages with the fixed ring 9. A driving assembly is provided on one side of the wedge block 8 to move it. The driving assembly includes a lead screw 2 rotatably connected to one side of the wedge block 8 via a bearing, and the lead screw 2 is threaded into a threaded groove inside the housing 1. The connection is achieved by rotating the lead screw 2 to move the wedge block 8. The lead screw 2 has a self-locking function, which can maintain the position of the wedge block 8 without applying additional external force, thus automatically locking it after it moves to the desired position. This effectively prevents the wedge block 8 from sliding due to external vibrations or other factors. By rotating the drive assembly, the wedge block 8 moves inward, and the inclined surface of the wedge block 8 pushes the fixing ring 9 upward. The fixing ring 9 drives the slider 10 upward, causing the insert 12 to disengage from the slot 11, thereby disengaging the valve stem 6. The operation process is extremely simple, involving moving the push... The actuator disengages the push mechanism from the fixed ring 9. Due to gravity, the fixed ring 9 and the slider 10 move downwards, causing multiple inserts 12 to engage with multiple slots 11. Through the cooperation of multiple inserts 12 and multiple slots 11, the slider 10 cannot rotate. The two limiting grooves 5 prevent the valve stem 6 from rotating, thus avoiding the problem of valve rotation due to valve design or external forces. This not only enhances the stability of valve operation but also effectively prevents the valve from affecting its closed or open state due to rotation, ensuring the normal operation and safe use of the valve.

[0023] In this embodiment, a second sliding groove 14 is provided inside the valve stem 6, and a slot 18 communicating with the second sliding groove 14 is provided at the top of the valve stem 6. A limiting block 15 is slidably connected in the second sliding groove 14. A fixing block 16 is fixed to the top of the limiting block 15 by bolts. A telescopic rod 17 passing through the slot 18 is rotatably connected to the top of the fixing block 16 by a bearing. By pulling the telescopic rod 17 upward, the telescopic end of the telescopic rod 17 is pulled out from the telescopic rod 17. If the telescopic rod 17 is pulled further, the telescopic rod 17 drives the fixing block 16 and the limiting block 15 to move upward until the fixing block 16 is moved to the position of the slot 18. Then, the telescopic rod 17 is rotated so that the telescopic rod 17 and the fixing block 16 form an L-shape. Then, the telescopic rod 17 is pushed to make a circular motion. The telescopic rod 17 drives the limiting block 15 and the valve stem 6 to rotate. Thus, through the amplification effect of the lever principle, a sufficiently large force can be easily transmitted to successfully start the valve, which greatly saves the physical strength and work efficiency of the staff and achieves the technical effect of saving labor and improving the convenience of operation.

[0024] In this embodiment, the limiting block 15 is a magnetic block that is attracted to the valve stem 6. By attracting the limiting block 15 to the valve stem 6, the limiting block 15 can be fixed at any position in the second slide groove 14 opened inside the valve stem 6. The limiting block 15 is elliptical cylindrical, and the elliptical cylindrical shape can prevent the limiting block 15 from rotating in the second slide groove 14.

[0025] In this embodiment, the top of each of the multiple inserts 12 is provided with an arc surface that facilitates the insertion of the insert 12 into the slot 11. The arc surface enables adaptive positioning, making the insert 12 more flexible and accurate when inserted into the slot 11. The telescopic rod 17 is made of alloy steel, which increases the rigidity of the telescopic rod 17 and makes it less prone to breakage.

[0026] Working principle and usage process of this utility model:

[0027] When the valve is not in use, rotating the lead screw 2 causes the wedge block 8 to slide along the first groove 7, disengaging the wedge block 8 from the fixing ring 9. The fixing ring 9 and the slider 10 move downwards due to gravity, causing multiple inserts 12 to engage with multiple slots 11. Through the cooperation of multiple inserts 12 and multiple slots 11, the slider 10 cannot rotate, and the valve stem 6 cannot rotate through the two limiting grooves 5, thus avoiding the influence of valve design or external forces.

[0028] When the valve needs to be started, first rotate the screw 2 to move the wedge block 8 inward. The inclined surface of the wedge block 8 pushes the fixing ring 9 upward. The fixing ring 9 moves the slider 10 upward, causing the insert block 12 to disengage from the slot 11. Then, pull the telescopic rod 17 upward, causing the telescopic end of the telescopic rod 17 to be pulled out from inside the telescopic rod 17. Continue to pull the telescopic rod 17, which causes the fixing block 16 and the limiting block 15 to move upward until the fixing block 16 is moved to the slot 18 position. Then, rotate the telescopic rod 17 so that the telescopic rod 17 and the fixing block 16 form an L-shape. Then, push the telescopic rod 17 to make a circular motion. The telescopic rod 17 causes the limiting block 15 and the valve stem 6 to rotate. Through the amplification effect of the lever principle, a large enough force can be easily transmitted to successfully start the valve.

[0029] The electronic components and modules used in this utility model can all be parts that are commonly used in the market and can achieve the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
