Description

Technical Field

[0001] The invention belongs to the technical field of valve instruments, and in particular relates to a valve-in-pipe with a cleaning mechanism. Background Art

[0002] A valve-in-pipe is a device used to control the flow and pressure of fluids in pipelines. By adjusting the position of the valve core or valve plate, the valve's degree of opening changes, thereby controlling the flow rate of the fluid in the pipeline. When the valve is open, fluid can flow freely; when the valve is closed, fluid cannot flow or can only pass through a very small channel. By varying the valve's degree of opening, the valve-in-pipe can regulate the fluid pressure in the pipeline. When the valve is fully open, the fluid faces less resistance and the pressure is relatively low. When the valve is closed or partially closed, the fluid faces greater resistance and the pressure is relatively high. In general, the valve-in-pipe controls fluid flow and pressure by controlling the valve's degree of opening, making it a crucial control element in pipeline systems.

[0003] Traditional in-pipe valves can meet most common usage scenarios, but in actual use, the fluid often contains solid impurities. These impurities will stick to the pipe wall and accumulate over time, eventually leading to pipe blockage. Some impurities are also corrosive and will corrode the pipe, which will shorten the service life of the equipment. Therefore, the pipe needs to be cleaned regularly to ensure the stable operation of the equipment, but this increases maintenance costs. In addition, it is very difficult to clean pipes with accumulated impurities, and the cleaning cost is high, which ultimately greatly increases the cost of use. Summary of the Invention

Not only can the inner wall of the liquid outlet pipe 2 be cleaned comprehensively, but the rotation of the cleaning ring 45 and the movement of the moving ring 42 can effectively improve the cleaning effect.

[0034] like Figures 8-10As shown, the traction mechanism 5 includes a traction rod 51, a traction rope 52 and a driving component 53. The traction rod 51 passes through the liquid outlet pipe 2 and is rotatably connected to the liquid outlet pipe 2.

A first adjusting gear 532 is fixedly connected to the bottom of the driving component 53 , and a first handle 533 is fixedly connected to the top of the driving component 53 .

[0035] In this embodiment, the rotation of the driving component 53 can drive the traction rod 51 to rotate, and the rotation of the traction rod 51 can tighten the traction rope 52, thereby pulling the base 421 to slide toward the valve tube 1, and the direction of the fluid is to flow away from the valve tube 1. When the fluid flows, it can drive the movable ring 42 to move away from the valve tube 1, and the rotation of the driving component 53 can pull the movable ring 42 to slide toward the valve tube 1, thereby realizing the reciprocating sliding of the cleaning mechanism 4 in the liquid outlet pipe 2, and more comprehensively cleaning the inner wall of the liquid outlet pipe 2.

[0036] like Figures 8-12 As shown, a rotating shaft 31 is fixedly connected to the top of the valve plate 3. The rotating shaft 31 passes through the valve pipe 1 and is rotatably connected to the valve pipe 1. A worm gear 32 is fixedly connected to the rotating shaft 31. A second adjusting gear 33 is fixedly connected to the rotating shaft 31 above the worm gear 32. A worm 61 is fixedly provided at one end of the adjusting rod 6, and a second handle 62 is fixedly provided at the other end of the adjusting rod 6. The worm wheel 32 is meshed with the worm 61.

Rotating the adjusting rod 6 can drive the worm 61 to rotate, and the rotation of the worm 61 can drive the worm wheel 32 to rotate, and the rotation of the worm wheel 32 can drive the valve plate 3 to rotate. That is, rotating the adjusting rod 6 can achieve the angle adjustment of the valve plate 3, that is, the opening and closing of the valve and the adjustment of the fluid flow and pressure; The self-locking property of the worm gear 32 and worm 61 mechanism ensures that the angle of the valve plate 3 is locked after the adjusting rod 6 has adjusted the angle of the valve plate 3, and the angle of the valve plate 3 will not be changed by the impact of the fluid flow, thus ensuring the stability of the adjustment. When the adjusting rod 6 adjusts the angle of the valve plate 3, it drives the driving component 53 to rotate. When the adjusting rod 6 opens the valve plate 3, the driving component 53 drives the traction rod 51 to rotate, thereby pulling the base 421 to slide toward the valve pipe 1, so that the cleaning mechanism 4 is ready to be pushed by the fluid to move away from the valve pipe 1 to clean the inner wall of the liquid outlet pipe 2.

That is, rotating the adjusting rod 6 can realize the angle adjustment of the valve plate 3, that is, the opening and closing of the valve and the adjustment of the fluid flow and pressure. After the valve is opened, the fluid enters the valve pipe 1 through the liquid inlet pipe, and then flows from the valve pipe 1 into the liquid outlet pipe 2; The self-locking property of the worm gear 32 and worm 61 mechanism ensures that the angle of the valve plate 3 is locked after the adjusting rod 6 has adjusted the angle of the valve plate 3, and the angle of the valve plate 3 will not be changed by the impact of the fluid flow, thus ensuring the stability of the adjustment; When the adjusting rod 6 adjusts the angle of the valve plate 3, it drives the driving component 53 to rotate. When the adjusting rod 6 opens the valve plate 3, the driving component 53 drives the traction rod 51 to rotate, thereby pulling the base 421 to slide toward the valve pipe 1, so that the cleaning mechanism 4 is ready to be pushed by the fluid to move away from the valve pipe 1 to clean the inner wall of the liquid outlet pipe 2; The first adjusting gear 532 is engaged with the second adjusting gear 33, so that when the angle of the valve plate 3 is locked, the driving component 53 can also be locked, that is, the traction mechanism 5 is locked, that is, the position of the cleaning mechanism 4 is locked, which is convenient for fixing the position of the cleaning mechanism 4 when the cleaning mechanism 4 is not in use. When the cleaning mechanism 4 needs to be moved, it is only necessary to lift the driving component 53, and the driving component 53 drives the first adjusting gear 532 to rise, and the first adjusting gear 532 is disengaged from the second adjusting gear 33. The driving component 53 can be unlocked, that is, the traction mechanism 5 is unlocked, and the cleaning mechanism 4 can move normally. After the valve is opened, the traction mechanism 5 is unlocked, and the cleaning mechanism 4 is pushed by the fluid to move away from the valve pipe 1. When the base 421 drives the movable ring 42 to slide on the track 41, the rack 411 can drive the driving gear 431 to rotate, and the rotation of the driving gear 431 can drive the driving rod 43 to rotate, and the rotation of the driving rod 43 can drive the first bevel gear 432 to rotate, and the rotation of the first bevel gear 432 can drive the transmission component 44 to rotate, and the rotation of the transmission component 44 can drive the transmission gear 441 to rotate, and the rotation of the transmission gear 441 can drive the ring gear 451 to rotate, and the rotation of the ring gear 451 can drive the cleaning ring 45 to rotate, and the rotation of the cleaning ring 45 can drive the cleaning scraper 452 to clean the inner wall of the liquid outlet pipe 2; Finally, the moving ring 42 slides on the track 41 while the cleaning ring 45 rotates on the moving ring 42. The rotation of the cleaning ring 45 drives the cleaning scraper 452 to rotate and clean the inner wall of the liquid outlet pipe 2. Not only can the inner wall of the liquid outlet pipe 2 be cleaned comprehensively, but the rotation of the cleaning ring 45 and the movement of the moving ring 42 can effectively improve the cleaning effect. The rotation of the driving component 53 can drive the traction rod 51 to rotate, and the rotation of the traction rod 51 can tighten the traction rope 52, thereby pulling the base 421 to slide toward the valve tube 1, and the direction of the fluid is to flow away from the valve tube 1. When the fluid flows, it can drive the movable ring 42 to move away from the valve tube 1, and the rotation of the driving component 53 can pull the movable ring 42 to slide toward the valve tube 1, thereby realizing the reciprocating sliding of the cleaning mechanism 4 in the liquid outlet pipe 2, and more comprehensively cleaning the inner wall of the liquid outlet pipe 2.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
