Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, specifically a fixed forged steel ball valve. Background Technology

[0002] Fixed forged steel ball valves are suitable for industrial scenarios requiring high reliability, corrosion resistance, and the ability to withstand high-pressure fluid control, such as liquid or gas pipeline systems in oil, chemical, natural gas transportation, hydropower stations, and large industrial equipment, ensuring the safe, stable, and efficient flow of the medium.

[0003] However, existing technologies still have the following problems:

[0004] In existing designs of stationary forged steel ball valves, the on / off operation is often complex and labor-intensive. Traditional operation methods require a large torque to rotate the ball valve core, which not only increases the physical exertion of operators, but may also lead to damage to the ball valve or a decrease in sealing performance due to improper operation. In addition, after long-term use, due to factors such as wear and corrosion, the rotational stability and sealing performance of the ball valve may be affected, which may lead to safety problems such as fluid leakage.

[0016] 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.

[0017] Example: Figure 1-3As shown, this utility model provides a fixed forged steel ball valve, including a base plate 1. A labor-saving mechanism 2 is fixedly mounted on the upper surface of the base plate 1. Multiple fixed mechanisms 3 arranged in a rectangular array are inserted into the upper surface of the base plate 1. The labor-saving mechanism 2 includes a valve frame 20. The lower surface of the valve frame 20 is fixedly connected to the base plate 1. A positioning rod 22 is fixedly mounted on the upper surface of the valve frame 20. A pull rod 23 is sleeved on the outer side of the positioning rod 22. A rotating ring 24 is slidably mounted on the outer side of the pull rod 23. A rotating plate 26 is fixedly mounted on the outer side of the rotating ring 24. A rotating rod 27 is fixedly mounted on the lower surface of the rotating plate 26. The rotating rod 27 rotates and engages with the inner side of the valve frame 20. A ball valve core 28 is fixedly mounted at the lower end of the rotating rod 27. When operating the labor-saving mechanism... When operating the valve, the operator first holds the anti-slip sleeve 25 at one end of the lever 23 to ensure stability and safety during operation. Then, by pulling the lever 23 along the direction of the positioning rod 22, the lever 23 will move the rotating ring 24 that is slidably mounted on its outer side. As the rotating ring 24 moves, the rotating plate 26 fixed to the outer side of the rotating ring 24 will also move. This, in turn, will cause the lower ball valve core 28 to rotate in the valve groove 29 inside the valve frame 20 via the rotating rod 27. This design allows the operator to easily rotate the ball valve core 28 with a small amount of force, thereby controlling the flow of fluid. At the same time, the sealing rings 21 on both sides of the valve frame 20 ensure the sealing performance of the ball valve in the closed state.

[0018] One end of the pull rod 23 is fixedly provided with an anti-slip sleeve 25. A valve groove 29 is opened on the inner side of the valve frame 20. The inner side of the valve groove 29 rotates and fits against the outer side of the ball valve core 28. Both sides of the valve frame 20 are provided with sealing rubber rings 21. The anti-slip sleeve 25 can ensure the stability and safety during operation. The sealing rubber rings 21 on both sides of the valve frame 20 ensure the sealing performance of the ball valve in the closed state.

[0019] The fixing mechanism 3 includes a fixing screw 31 located on the upper surface of the base plate 1. An expansion nut 33 is threaded onto the outer side of the fixing screw 31. An expansion rod 38 is fixed to the lower end of the fixing screw 31, and an expansion block 37 is fixed to the lower end of the expansion rod 38. An expansion cylinder 34 is slidably fitted onto the outer side of the expansion rod 38. An expansion opening 35 is provided at the lower end of the expansion cylinder 34, and the lower end of the expansion cylinder 34 slides against the outer side of the expansion block 37. Using the fixing mechanism 3, the operator first passes the fixing screw 31 through the fixing hole 30 on the upper surface of the base plate 1 and inserts the lower end of the fixing screw 31 into the desired fixing position. Then, by rotating the expansion nut 33, it moves downwards on the outer thread of the fixing screw 31. As the expansion nut 33 rotates and descends, it will press against the upper surface of the base plate 1 and push the fixing screw 31 outward. At the same time, the expansion cylinder 34 is in a fixed position and is fitted against the inner wall, so that the fixing screw 31 will make the expansion opening 35 at the lower end of the expansion cylinder 34 fit tightly against the outer side of the expansion block 37 during the movement. At this time, the expansion cylinder 34 is deformed by the thrust of the expansion nut 33, and then it will tightly bite the position to be fixed by opening the expansion opening 35, so as to achieve a stable fixing effect. In order to enhance the stability of the fixing, anti-loosening washers 32 are provided on both the upper and lower surfaces of the expansion nut 33 to prevent loosening caused by vibration and other factors. In addition, the anti-slip texture 36 on the outer side of the expansion cylinder 34 increases the friction.

[0020] The upper surface of the base plate 1 has multiple fixing holes 30 arranged in a rectangular array. The fixing holes 30 slide against the outer side of the fixing screw 31. The upper and lower surfaces of the expansion nut 33 are provided with anti-loosening washers 32. The anti-loosening washers 32 slide against the fixing screw 31. The outer side of the expansion cylinder 34 is fixed with multiple anti-slip patterns 36. The upper and lower surfaces of the expansion nut 33 are provided with anti-loosening washers 32 to prevent loosening caused by vibration and other factors. The anti-slip patterns 36 on the outer side of the expansion cylinder 34 are designed to increase friction.

[0021] Working principle: When operating the labor-saving mechanism 2, the operator first holds the anti-slip sleeve 25 at one end of the pull rod 23 to ensure stability and safety during operation. Then, by pulling the pull rod 23 along the direction of the positioning rod 22, the pull rod 23 will drive the rotating ring 24 slidably set on its outer side to move together. As the rotating ring 24 moves, the rotating plate 26 fixed on the outer side of the rotating ring 24 will also move accordingly. Then, through the rotating rod 27, the lower ball valve core 28 will rotate in the valve groove 29 inside the valve frame 20. This design allows the operator to easily rotate the ball valve core 28 with a small force, thereby controlling the flow of fluid. At the same time, the sealing rings 21 on both sides of the valve frame 20 ensure the sealing performance of the ball valve in the closed state.

[0022] Using the fixing mechanism 3, the operator first inserts the fixing screw 31 through the fixing hole 30 on the upper surface of the base plate 1 and inserts the lower end of the fixing screw 31 into the position to be fixed. Then, by rotating the expansion nut 33, it moves downward on the outer thread of the fixing screw 31. As the expansion nut 33 rotates and descends, it will press against the upper surface of the base plate 1 and push the fixing screw 31 outward. At the same time, the expansion cylinder 34 is in contact with the inner wall at the fixed position, so that the expansion opening 35 at the lower end of the expansion cylinder 34 will be tightly in contact with the outer side of the expansion block 37 during the movement of the fixing screw 31. At this time, the expansion cylinder 34 is deformed by the thrust of the expansion nut 33, and then tightly bites the position to be fixed by opening the expansion opening 35, achieving a stable fixing effect. In order to enhance the stability of the fixing, anti-loosening washers 32 are provided on both the upper and lower surfaces of the expansion nut 33 to prevent loosening caused by vibration and other factors. In addition, the anti-slip texture 36 on the outer side of the expansion cylinder 34 increases the friction.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
