Description

Technical Field

[0001] This invention belongs to the field of pumped storage technology, specifically a ball valve sealing device for a pumped storage unit. Background Technology

[0002] Ball valves are widely used in industries such as petroleum refining, long-distance pipelines, chemical industry, papermaking, pharmaceutical industry, water conservancy, power, municipal engineering, and steel. Ball valves in pumped storage units are generally used to control the water flow in high-pressure water supply pipelines. They have excellent shut-off characteristics and flow regulation capabilities. The main body of a ball valve consists of a ball and a valve seat on the ball. Water flow is controlled by rotating the ball when opening and closing.

[0003] When using ball valves for sealing, the operator rotates the handle to turn the valve and seal the pumped storage unit. However, the large water flow creates significant resistance when the operator turns the handle, making it more strenuous and prolonging the sealing time. Furthermore, with traditional sealing methods, there is a risk that the rotation angle may exceed the required sealing angle, resulting in ineffective sealing. Therefore, improvements are needed. Summary of the Invention

[0004] To address the issue raised in the background art that the excessive water flow speed creates resistance when the operator rotates the handle, making rotation more strenuous and potentially causing the rotation angle to exceed the required sealing angle, this invention provides a ball valve sealing device for pumped storage units. The ball valve is most suitable for use as a switch or shut-off valve, and its main function is to cut off or connect the fluid flow in the pipeline.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a ball valve sealing device for a pumped storage unit, comprising a valve body, a downstream connecting pipe movably connected to one side of the valve body, an upstream connecting pipe movably connected to the side of the valve body away from the downstream connecting pipe, a fixed box fixedly installed on the top of the valve body, a ball piston movably connected to the inner cavity of the valve body, an adjusting component movably connected to the inner top of the upstream connecting pipe, a sealing component fixedly installed in the inner cavity of the fixed box, a second gear located in the inner cavity of the fixed box fixedly installed on the top of the ball piston, and a spring plate located in the inner cavity of the fixed box fixedly installed on the outer wall of the upper end of the ball piston.

[0006] Preferably, the adjusting component includes a connecting shaft, which is movably connected to an upstream connecting pipe. A rectangular block is fixedly connected to the bottom of the connecting shaft, and a first gear is fixedly installed at the upper end of the connecting shaft. A handwheel is fixedly installed on the top of the first gear.

[0007] Preferably, the sealing assembly includes a rectangular plate and a locking block. The rectangular plate is movably connected to the fixed box. A toothed plate is abutting against the rectangular plate. A first spring telescopic rod is fixedly installed at the end of the toothed plate away from the rectangular plate. A connecting plate is fixedly connected to the middle of the locking block. A second spring telescopic rod is fixedly installed at the top of the connecting plate.

[0008] Preferably, the top of the rectangular plate has a groove, and a handle is provided on the side of the rectangular plate away from the toothed plate.

[0009] Preferably, the side of the rectangular plate closest to the toothed plate is an inclined surface, and the side of the toothed plate closest to the rectangular plate is an inclined surface.

[0010] Preferably, the second spring telescopic rod is fixedly connected to the bottom surface of the top of the fixed box, and the top of the locking block is provided with an arc-shaped handle.

[0011] Preferably, the fixing box has slots on the side near the adjustment component and near the rectangular plate, and protrusions are fixedly installed inside the slots.

[0012] Preferably, the fixed box and the ball piston are movably connected, and the first gear is meshed with the gear plate.

[0013] Preferably, a connecting rod is movably connected to the middle of the connecting shaft, and the end of the connecting rod away from the connecting shaft is fixedly connected to the valve body.

[0014] Preferably, a groove is provided at the bottom of the toothed plate, and a slider fixing block is fixedly installed at the bottom of the inner cavity of the fixing box.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] This invention, through the coordinated design of various structures, facilitates sealing operations for operators and reduces the sealing time of the pumped-storage unit due to water resistance. A rectangular plate is pushed into the inner cavity of the fixed box, causing it to abut against a toothed plate, which moves the toothed plate to the left. This leftward movement of the toothed plate drives the first gear to rotate, which in turn drives the rectangular block and connecting shaft to rotate. The rotation of the rectangular block reduces the water flow through the upstream connecting pipe. Continuing to push the rectangular plate, the toothed plate drives the second gear to rotate, which in turn drives the ball piston to rotate. This pushes the rectangular plate so that the locking block engages with the groove at the top of the rectangular plate, ensuring that the rotation angle of the ball piston is exactly the required sealing angle for the pumped-storage unit. This achieves the effect of ensuring that the ball valve rotates at the required sealing angle when sealing the pumped-storage unit. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] like Figures 1 to 6 As shown, the present invention provides a ball valve sealing device for a pumped storage unit, comprising a valve body 1, a downstream connecting pipe 2 movably connected to one side of the valve body 1, an upstream connecting pipe 9 movably connected to the side of the valve body 1 away from the downstream connecting pipe 2, a fixed box 3 fixedly installed on the top of the valve body 1, a ball piston 4 movably connected to the inner cavity of the valve body 1, an adjusting component 5 movably connected to the inner top of the upstream connecting pipe 9, a sealing component 6 fixedly installed in the inner cavity of the fixed box 3, a second gear 7 fixedly installed on the top of the ball piston 4 in the inner cavity of the fixed box 3, and a spring plate 8 fixedly installed on the outer wall of the upper end of the ball piston 4 in the inner cavity of the fixed box 3.

[0026] The above scheme is adopted as follows: by adjusting the cooperation of component 5 and sealing component 6, the rectangular plate 602 is pushed into the inner cavity of the fixed box 3. The rectangular plate 602 abuts against the toothed plate 601, causing the toothed plate 601 to move to the left. The leftward movement of the toothed plate 601 drives the first gear 501 to rotate. The first gear 501 drives the rectangular block 503 and the connecting shaft 504 to rotate. The rotation of the rectangular block 503 reduces the water flow through the upstream connecting pipe 9, continuously pushing the rectangular plate 602, causing the toothed plate 601 to drive the second gear 7 to rotate. The second gear 7 drives the ball piston 4 to rotate, pushing the rectangular plate 602 so that the locking block 604 is locked into the groove at the top of the rectangular plate 602, so that the rotation angle of the ball piston 4 is exactly the required sealing angle of the pumped storage unit.

[0027] like Figure 2 , Figure 5 , Figure 6 As shown, the adjusting component 5 includes a connecting shaft 504, which is movably connected to the upstream connecting pipe 9. A rectangular block 503 is fixedly connected to the bottom of the connecting shaft 504, and a first gear 501 is fixedly installed at the upper end of the connecting shaft 504. A handwheel 502 is fixedly installed at the top of the first gear 501. The sealing component 6 includes a rectangular plate 602 and a locking block 604. The rectangular plate 602 is movably connected to the fixed box 3. A toothed plate 601 is abutted against the rectangular plate 602. A first spring telescopic rod 603 is fixedly installed at the end of the toothed plate 601 away from the rectangular plate 602. A connecting plate 606 is fixedly connected to the middle of the locking block 604. A second spring telescopic rod 605 is fixedly installed at the top of the connecting plate 606. A groove is provided at the top of the rectangular plate 602, and a handle is provided on the side of the rectangular plate 602 away from the toothed plate 601.

[0028] The above scheme is adopted: through the cooperation of the first gear 501 and the handwheel 502, the gear plate 601 drives the first gear 501 to rotate, and the first gear 501 drives the rectangular block 503 and the connecting shaft 504 to rotate, thereby reducing the water flow. The reduced water flow makes it easier to seal the pumped storage unit. Through the cooperation of the gear plate 601 and the rectangular plate 602, the rectangular plate 602 abuts against the gear plate 601, causing the gear plate 601 to move to the right. When the gear plate 601 meshes with the second gear 7, it drives... The second gear 7 and the ball piston 4 rotate until the locking block 604 engages with the slot at the top of the rectangular plate 602. At this point, the ball piston 4 rotates ninety degrees, completely sealing the pumped storage unit. Due to the design of the rectangular plate 602, the groove design ensures that when the rectangular plate 602 is pushed inward and the locking block 604 engages with the groove of the rectangular plate 602, the ball piston 4 rotates exactly ninety degrees, thereby sealing the pumped storage unit and avoiding the problem of the rotation angle exceeding the angle required for sealing.

[0029] like Figure 2 , Figure 3, Figure 5 , Figure 6 As shown, the side of the rectangular plate 602 near the toothed plate 601 is inclined, and the side of the toothed plate 601 near the rectangular plate 602 is inclined. The second spring telescopic rod 605 is fixedly connected to the bottom surface of the top of the fixed box 3. The top of the locking block 604 is provided with an arc-shaped handle. The fixed box 3 is provided with slots on the side near the adjusting component 5 and near the rectangular plate 602, and a protrusion is fixedly installed inside the slot. The fixed box 3 and the ball piston 4 are movably connected. The first gear 501 is meshed with the toothed plate 601. A connecting rod is movably connected to the middle of the connecting shaft 504, and the end of the connecting rod away from the connecting shaft 504 is fixedly connected to the valve body 1. A sliding groove is provided at the bottom of the toothed plate 601. A slider fixing block is fixedly installed at the bottom of the inner cavity of the fixed box 3.

[0030] The above solution employs the following: Through the cooperation of the toothed plate 601 and the rectangular plate 602, the inclined design allows the rectangular plate 602 to be pushed inwards, and when it contacts the toothed plate 601, the contact is quicker, reducing the jerky feeling. The design of the second spring telescopic rod 605, which is fixedly connected to the bottom surface of the top of the fixing box 3, secures the locking block 604 and the connecting plate 606. The handle on the top of the locking block 604 makes it easier to remove it from the groove in the rectangular plate 602. The design of the fixing box 3 includes slots that are movably connected to both the rectangular plate 602 and the toothed plate 601. The protrusions fixedly installed inside the slots provide a secure connection between the toothed plate 601 and the rectangular plate 602, ensuring smooth contact. 602 is more stable when moving. Through the cooperation of the fixed box 3 and the ball piston 4, the toothed plate 601 drives the second gear 7 to rotate, and the second gear 7 drives the ball piston 4 to rotate, thereby sealing the pumped storage unit. The first gear 501 and the toothed plate 601 are meshed and connected, so that when the toothed plate 601 moves, it drives the first gear 501 to rotate, thereby driving the rectangular block 503 and the connecting shaft 504 to rotate. The rectangular block 503 reduces the water flow, making the sealing more effortless. Through the design of the connecting shaft 504 and the design of the fixed rod, the adjustment component 5 is limited as a whole, making the rotation of the connecting shaft 504 driven by the first gear 501 more stable. Through the cooperation of the toothed plate 601 and the fixed box 3, and the cooperation of the fixed block and the slide, the toothed plate 601 is limited, thereby making the toothed plate 601 more stable when moving.

[0031] Working principle and usage process of this invention:

[0032] In use, the rectangular plate 602 is pushed into the inner cavity of the fixed box 3. The rectangular plate 602 abuts against the toothed plate 601, causing the toothed plate 601 to move to the left. The leftward movement of the toothed plate 601 drives the first gear 501 to rotate. The first gear 501 drives the rectangular block 503 and the connecting shaft 504 to rotate. The rotation of the rectangular block 503 reduces the water flow through the upstream connecting pipe 9. The reduced water flow reduces water resistance, making it easier for the operator to perform the sealing. This reduces the time required to seal the pumped storage unit. Continuing to push the rectangular plate 602 causes the toothed plate 601 to drive the second gear 7 to rotate. The second gear 7 drives the ball piston 4 to rotate, pushing the rectangular plate 602 so that the locking block 604 is engaged in the groove at the top of the rectangular plate 602. This ensures that the rotation angle of the ball piston 4 is exactly the required sealing angle of the pumped storage unit, thus quickly sealing it.

[0033] When the ball valve of the pumped storage unit is opened, hold the arc-shaped handle on the top of the locking block 604 and pull the locking block 604 upwards so that the locking block 604 is no longer locked to the rectangular plate 602. At this time, the spring plate 8 drives the ball piston 4 to rotate, so that the ball piston 4 is connected to the downstream connecting pipe and the upstream connecting pipe 9. When the ball piston 4 rotates, the second gear 7 drives the toothed plate 601 to move back to its original position. The toothed plate 601 abuts against the rectangular plate 602, so that the toothed plate 601 returns to its original position. When the toothed plate 601 moves, the toothed plate 601 drives the first gear 501 to rotate. The first gear 501 drives the rectangular block 503 and the connecting shaft 504 to rotate, so that the inner cavity of the rectangular block 503 and the upstream connecting pipe 9 are parallel, thereby increasing the area through which water flows from the inner cavity of the upstream connecting pipe 9.
