Description

Technical Field

[0001] This utility model relates to the field of pipeline valve technology, and in particular to a high-flow-rate, straight-through double-joint ball valve that is easy to adjust the water flow rate. Background Technology

[0002] This high-flow-rate, straight-through, double-joint ball valve is commonly used to control and regulate water flow in pipelines. A specially designed ball valve, it enables precise flow control under high-flow conditions. Combining the basic characteristics of a ball valve, it is suitable for various applications requiring flow rate regulation. This valve allows for rapid opening and closing, regulating fluid flow through partial opening or closing.

[0003] In existing technologies, some high-flow-rate, straight-through double-joint ball valve devices for regulating water flow speed involve rotating the valve stem when the operating handle or actuator drives it to rotate, causing the ball to rotate synchronously. The ball has a circular through-hole inside. When the ball is fully aligned with both ends of the valve body, the valve is fully open, allowing fluid to pass freely. When the ball rotates 90 degrees, the through-hole is perpendicular to the valve body, and the valve is closed, preventing fluid flow. However, in some high-flow-rate, straight-through double-joint ball valve devices for regulating water flow speed, if operators forget to add lubricant regularly to lubricate the ball valve and the pipeline, the friction between the ball and the pipeline increases, making operation difficult. The ball may not rotate accurately to 90 degrees, resulting in inaccurate control of the ball's ability to block water flow. Utility Model Content

[0004] This utility model proposes a high-flow-rate straight-through double-joint ball valve that facilitates the adjustment of water flow speed. It aims to improve the problem in some existing high-flow-rate straight-through double-joint ball valve devices that do not have lubricant added for a long time, resulting in increased friction between the ball and the pipe, making it impossible to accurately control the ball's obstruction of water flow.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A high-flow-rate, straight-through, double-joint ball valve for easy water flow speed adjustment includes a water pipe. An elliptical tube is fixedly connected to the outside of the water pipe. A ball valve one is rotatably connected to the inner wall of the elliptical tube. A rotating rod one is fixedly connected to the top of the ball valve one, extending through and to the outside of the elliptical tube. A ball valve two is rotatably connected to the inner wall of the ball valve one. A rotating rod two is fixedly connected to the top of the ball valve two. A connecting rod is fixedly connected to the top of the elliptical tube. A fixing ring one is fixedly connected to the outside of the connecting rod. A blocking block one is fixedly connected to the inner wall of the fixing ring one. A fixing ring two is fixedly connected to the outside of the connecting rod. A contact block one is fixedly connected to the outside of the rotating rod one. A grip ring one is fixedly connected to the outside of the rotating rod one. A blocking block two is fixedly connected to the top of the grip ring one. A contact block two is fixedly connected to the outside of the rotating rod two. A handle two is fixedly connected to the top of the rotating rod two. The ball valve one and ball valve two are designed to rotate accurately by 90 degrees to control the water flow through or be blocked within the elliptical tube.

[0007] As a further description of the above technical solution:

[0008] The bottom of the elliptical tube is provided with a base, the inside of which is provided with a threaded groove one, and the inner wall of which is provided with a threaded groove two, in order to fix the threaded ring rod three and the threaded rod four.

[0009] As a further description of the above technical solution:

[0010] The inner wall of the threaded groove is threaded with a threaded ring rod three, and the top of the threaded ring rod three is fixedly connected with a slide rod one, so that the ball valve one can rotate smoothly by 90 degrees.

[0011] As a further description of the above technical solution:

[0012] The inner wall of the threaded groove two is threadedly connected to a threaded rod four, and the top of the threaded rod four is fixedly connected to a slide rod three, so that the ball valve two can rotate smoothly by 90 degrees.

[0013] As a further description of the above technical solution:

[0014] The bottom of ball valve one is fixedly connected to a receiving rod one, and the bottom of ball valve two is fixedly connected to a sliding rod four. The outside of the receiving rod one is fixedly connected to a sliding rod two. The outside of the sliding rod one is slidably connected to the inner wall of the sliding rod two, and the outside of the sliding rod three is slidably connected to the inner wall of the sliding rod four. This is to make it easier for ball valve one and ball valve two to rotate to 90 degrees.

[0015] As a further description of the above technical solution:

[0016] The inner wall of the rotating rod is provided with an annular groove, the inner wall of the rotating rod is provided with a through hole, and the bottom inner wall of the rotating rod is provided with a through hole, so as to allow lubricating oil to flow.

[0017] As a further description of the above technical solution:

[0018] The rotating rod is fixedly connected to the outside of the pipe 2, and the pipe 2 is fixedly connected to the outside of the oil pump. The input end of the oil pump is fixedly connected to the pipe 1, and one end of the pipe 1 is fixedly connected to the storage tank. The storage tank and the oil pump are set inside the protective box in order to draw lubricating oil and send it to the annular groove.

[0019] As a further description of the above technical solution:

[0020] The top of the protective box is fixedly connected to a hinge, and a cover is fixedly connected to the bottom of one side of the hinge. The second rotating rod is rotatably connected to the inner wall of the first rotating rod, and the outer side of the first rotating rod is rotatably connected to the inner walls of the first and second fixing rings in order to cover the protective box.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, when the rotating rod one rotates, it drives the contact block one and the blocking block two to rotate. When the contact block one rotates and contacts the blocking block one, the rotating rod one and the ball valve one rotate exactly 90 degrees. Then, rotating the rotating rod two drives the contact block two to rotate. When the contact block two contacts the blocking block two, the rotating rod two also rotates exactly 90 degrees, so as to ensure that even if the friction between the ball and the pipe increases, the ball can still rotate 90 degrees.

[0023] 2. In this utility model, the oil pump is started to draw lubricating oil from inside the storage tank, which is then sent to the annular groove through the second pipe. Subsequently, it flows through the first through-hole between the first and second rotating rods, and then flows down to the space between the first and second ball valves. The lubricating oil also flows through the second through-hole to the space between the first ball valve and the elliptical tube, achieving a lubrication effect and making the ball valve rotate more smoothly.

[0035] 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.

[0036] Reference Figures 1 to 3An embodiment of this utility model provides a high-flow-rate, straight-through double-joint ball valve that facilitates water flow speed adjustment. It includes a water pipe 1, an elliptical pipe 2 fixedly connected to the outside of the water pipe 1, a ball valve 3 rotatably connected to the inner wall of the elliptical pipe 2, a rotating rod 4 fixedly connected to the top of the ball valve 3, and the rotating rod 4 penetrating and extending to the outside of the elliptical pipe 2. A ball valve 5 rotatably connected to the inner wall of the ball valve 3, a rotating rod 6 fixedly connected to the top of the ball valve 5, a connecting rod 7 fixedly connected to the top of the elliptical pipe 2, a fixing ring 8 fixedly connected to the outside of the connecting rod 7, a blocking block 9 fixedly connected to the inner wall of the fixing ring 8, and a fixing ring 10 fixedly connected to the outside of the connecting rod 7.

[0037] Reference Figures 3 to 5 The rotating rod 4 is externally fixedly connected to a contact block 11, and the rotating rod 4 is externally fixedly connected to a grip ring 13. The top of the grip ring 13 is fixedly connected to a blocking block 12. The rotating rod 6 is externally fixedly connected to a contact block 14, and the top of the rotating rod 6 is fixedly connected to a handle 15. In order to allow ball valve 3 and ball valve 5 to rotate 90 degrees accurately, the water flow is controlled to pass through or be blocked in the elliptical tube 2.

[0038] Reference Figure 5 , Figure 8 and Figure 9 The bottom of the elliptical tube 2 is provided with a base 16. The inside of the base 16 is provided with a threaded groove 17 and the inner wall of the base 16 is provided with a threaded groove 28. In order to fix the threaded ring rod 3 19 and the threaded rod 4 23, the inner wall of the threaded groove 17 is threadedly connected to the threaded ring rod 3 19. The top of the threaded ring rod 3 19 is fixedly connected to the slide rod 20 so that the ball valve 3 can rotate smoothly by 90 degrees.

[0039] Reference Figure 8 , Figure 9 The inner wall of the threaded groove 218 is threaded with a threaded rod 423. The top of the threaded rod 423 is fixedly connected with a slide rod 324. In order for the ball valve 25 to rotate smoothly by 90 degrees, the bottom of the ball valve 13 is fixedly connected with a receiving rod 122, and the bottom of the ball valve 25 is fixedly connected with a slide rod 425. The outside of the receiving rod 122 is fixedly connected with a slide rod 21. The outside of the slide rod 120 is slidably connected to the inner wall of the slide rod 21, and the outside of the slide rod 324 is slidably connected to the inner wall of the slide rod 425. This is to make the rotation of the ball valve 13 and the ball valve 25 to 90 degrees smoother.

[0040] Reference Figure 4 , Figure 6 and Figure 7The inner wall of the rotating rod 4 has an annular groove 33 and a through hole 34. The bottom inner wall of the rotating rod 4 has a through hole 35 for allowing lubricating oil to flow. The rotating rod 4 is fixedly connected to the outside of a pipe 32. An oil pump 31 is fixedly connected to the outside of the pipe 32. The input end of the oil pump 31 is fixedly connected to a pipe 30. One end of the pipe 30 is fixedly connected to a storage tank 29. The storage tank 29 and the oil pump 31 are located inside the protective box 26. In order to draw lubricating oil to the annular groove 33, a hinge 27 is fixedly connected to the top of the protective box 26. A cover 28 is fixedly connected to the bottom side of the hinge 27. The rotating rod 6 is rotatably connected to the inner wall of the rotating rod 4. The outside of the rotating rod 4 is rotatably connected to the inner walls of the fixed ring 8 and the fixed ring 10 to cover the protective box 26.

[0041] Working principle: To allow water to flow through the elliptical tube 2 from pipe 1, grip ring 13 and rotate it. This rotates rotating rod 4 and blocking block 12, which in turn rotates contact block 11, ball valve 3, and receiving rod 22. When contact block 11 rotates and contacts blocking block 9, rotating rod 4 and ball valve 3 rotate 90 degrees. At this point, contact block 11 is blocked by blocking block 9, and rotating rod 4 cannot continue to rotate. The circular through hole of ball valve 3 is aligned with water pipe 1, allowing water to flow through. Connecting rod 7 connects fixing ring 8 and fixing ring 10, ensuring that rotating rod 4 rotates smoothly.

[0042] When the ball valve 2 inside ball valve 3 still obstructs the water flow, in order to allow the water flow to pass through ball valve 2, grip handle 2 15 and rotate it, which drives rotating rod 2 6 to rotate, thereby driving contact block 2 14, ball valve 2 5 and slide rod 4 25 to rotate. Before this, blocking block 2 12 was rotated 90 degrees by grip ring 1 13. When contact block 2 14 rotates and comes into contact with blocking block 2 12, contact block 2 14 is blocked by blocking block 2 12. At this time, ball valve 2 5 rotates 90 degrees, and the water flow can pass through ball valve 3 and ball valve 2 5.

[0043] When ball valve 25 rotates, it drives slide rod 45 to rotate, which in turn drives slide rod 324 and threaded rod 423 to rotate. The base 16, connected to threaded ring rod 319, will not move with the rotation of threaded rod 423. When threaded rod 423 rotates upward, it will cause slide rod 324 to slide against the inner wall of slide rod 425 until ball valve 25 rotates 90 degrees, at which point slide rod 324 stops sliding. If ball valve 25 is to be accurately returned to its original position and block the water flow, handle 215 needs to be held and rotated in the opposite direction, which will drive rotating rod 26, ball valve 25, slide rod 425, slide rod 324, and threaded rod 423 to rotate in the opposite direction. Threaded rod 423 will slide back to the bottom of threaded groove 218, and slide rod 324 will slide out of slide rod 425 until the bottom of threaded rod 423 contacts the bottom inner wall of slide rod 324, at which point threaded rod 423 can no longer rotate, ensuring that ball valve 25 and rotating rod 26 will return to their original positions.

[0044] When the receiving rod 22 rotates 90 degrees, it drives the sliding rod 21, sliding rod 20, and threaded ring rod 19 to rotate. Simultaneously, the base 16, connected to the threaded rod 23, will not move with the rotation of the threaded ring rod 19. When the threaded ring rod 19 moves upward, it will press against the sliding rod 20 and slide into the sliding rod 21. When the ball valve 3 wants to accurately return to its original position, grip the handle 13 and rotate it in the opposite direction, driving the rotating rod 4, ball valve 3, receiving rod 22, sliding rod 21, sliding rod 20, and threaded ring rod... When threaded ring rod 19 rotates in the reverse direction, it slides back to the bottom of threaded groove 17. Slide rod 20 slides out of slide rod 21 until the bottom of threaded ring rod 19 contacts the bottom inner wall of threaded groove 17. At this point, threaded ring rod 19 can no longer rotate, ensuring that ball valve 3 and rotating rod 4 will return to their original positions. Furthermore, slide rods 20 and 21, along with slide rods 24 and 25, ensure that the horizontal height of base 16 does not change when threaded rod 23 and threaded ring rod 19 slide upwards or downwards.

[0045] The oil pump 31 is started to draw lubricating oil from the storage tank 29 through pipe 30 and delivers it to the annular groove 33 of the rotating rod 4 through pipe 32. The lubricating oil flows in the annular groove 33 and flows through the through hole 34 into the gap between the rotating rod 4 and the rotating rod 6. It flows down the gap until it reaches the space between ball valve 3 and ball valve 5, ensuring smoother rotation between ball valve 3 and ball valve 5, and between the rotating rod 4 and the rotating rod 6. When the lubricating oil reaches the through hole 35, it flows out through the through hole 35 and continues to flow down to the space between ball valve 3 and elliptical tube 2, ensuring smoother rotation between ball valve 3 and elliptical tube 2. When the storage tank 29 needs to be replenished with lubricating oil, or when the oil pump 31 is damaged, the cover 28 is opened through the hinge 27 to replenish the storage tank 29 with lubricating oil, or to continue repairing the oil pump 31.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
