Description

Technical Field

[0001] The utility model relates to the technical field of pipeline joints, in particular to an anti-corrosion pipeline joint. Background Art

[0002] Pipe joints are the connection tools between pipes and are the detachable connection points between components and pipes. They play an indispensable role in pipe fittings and are one of the two main components of hydraulic pipes. Pipe joints are used for straight-line connections such as instruments, and the connection forms include socket welding or threaded connection. The structural form should adopt a metal surface contact sealing structure. The gasket sealing structure is usually used in general pipelines for conveying water, oil, air, etc., and is made of malleable cast iron.

[0003] However, in the prior art, after the fluid flows through the pipe joint, the inner wall thereof will often be adhered to residual fluid. If the residual fluid is not cleaned in time, the fluid remaining on the inner wall of the pipe joint may corrode the inner wall of the pipe joint, and the pipe joint may leak after long-term corrosion, eventually causing the pipe joint to fail to be used normally.

[0010] The beneficial effects of the utility model are as follows:

[0011] 1. The utility model seals the interface between the connecting pipe and the external pipe by arranging an annular gasket and a sealing ring, and connects the connecting pipe and the external pipe together through a locking sleeve thread. When the end face of the external pipe contacts the annular gasket, the annular gasket slides into the fixed ring under the force of mutual squeezing between the external pipe and the connecting pipe.

When fluid passes through the connecting pipe, the turbofan drives the rotating shaft to rotate under the impact of the fluid, and the rotating shaft drives the scraper to rotate together. The scraper rotates to clean the inner wall of the connecting pipe. When no fluid flows in the connecting pipe, the turbofan continues to rotate under the action of inertia force. At this time, the scraper rotates to scrape off the residual fluid attached to the inner wall of the connecting pipe, thereby preventing part of the fluid from remaining on the inner wall of the connecting pipe and corroding the inner wall of the connecting pipe.

[0013] 3. The utility model buffers the impact force of the fluid on the surface of the turbofan by arranging a compression spring. When fluid passes through the connecting pipe, the turbofan drives the rotating shaft to rotate under the impact of the fluid.

[0020] Example: See Figure 1 - Figure 4The utility model provides a technical solution: an anti-corrosion pipe joint, comprising a connecting pipe 1, a locking sleeve 2 is slidably connected to the outer surface of the connecting pipe 1, a turbofan 3 is arranged inside the locking sleeve 2, a rotating shaft 4 is fixedly connected to the outer surface of the turbofan 3, a scraper 5 is slidably connected to the outer surface of the rotating shaft 4, a shaft sleeve 6 is arranged inside the scraper 5, a fixing ring 7 is arranged outside the shaft sleeve 6, a sealing ring 8 is arranged inside the fixing ring 7, a connecting ring 13 is fixedly connected to the outer surface of the sealing ring 8, the outer surface of the connecting ring 13 is slidably connected to the inner surface of the connecting pipe 1, a compression spring 9 is arranged inside the connecting pipe 1, a fixing frame 12 is fixedly connected to the inner surface of the connecting pipe 1, and a sleeve is rotatably connected to the inner surface of the fixing frame 12 10. The inner surface of the collar 10 is slidably connected to the outer surface of the shaft 4, and the outer surface of the scraper 5 is in contact with the inner surface of the connecting pipe 1. When fluid passes through the connecting pipe 1, the turbofan 3 drives the shaft 4 to rotate under the impact of the fluid. When the shaft 4 rotates, the collar 10 rotates along the inner surface of the fixing frame 12. The compression spring 9 can buffer the impact force of the fluid on the surface of the turbofan 3, so that the shaft 4 can slide slightly relative to the collar 10. The shaft sleeve 6 can make the two shafts 4 rotate together. The block 11 can make the shaft 4 slide relative to the shaft 4 while driving the collar 10 and the scraper 5 to rotate, thereby preventing the turbofan 3 from being damaged due to excessive fluid impact force, thereby extending the service life of the turbofan 3.

[0021] The inner surface of the sleeve 6 is slidably connected to the outer surface of the rotating shaft 4, and the outer surface of the rotating shaft 4 is fixedly connected with a block 11, the outer surface of the block 11 is slidably connected to the inner surface of the collar 10, the outer surface of the collar 10 is fixedly connected to the outer surface of the scraper 5, the inner surface of the scraper 5 is slidably connected to the inner surface of the block 11, the outer surface of the collar 10 is fixedly connected to the outer surface of the compression spring 9, and the end of the compression spring 9 away from the collar 10 is fixedly connected to the outer surface of the turbofan 3. When no fluid flows in the connecting pipe 1, the turbofan 3 continues to rotate under the action of inertia. At this time, the scraper 5 rotates to scrape off the residual fluid attached to the inner wall of the connecting pipe 1 to prevent part of the fluid from remaining on the inner wall of the connecting pipe 1 and corroding the inner wall of the connecting pipe 1.

[0022] The inner surface of the connecting pipe 1 is fixedly connected with a connecting pipe 14, the outer surface of the connecting pipe 14 is fixedly connected with the outer surface of the fixing ring 7, the inner surface of the fixing ring 7 is fixedly connected with the outer surface of the connecting pipe 1, the inner surface of the connecting pipe 14 is slidably connected with a piston rod 15, the outer surface of the piston rod 15 is fixedly connected with an annular pad 16, the outer surface of the annular pad 16 is slidably connected with the inner surface of the fixing ring 7, the inner surface of the fixing ring 7 is slidably connected with the outer surface of the piston rod 15, the connecting pipe 1 is threadedly connected with the external pipeline through the locking sleeve 2, When the end face of the external pipe contacts the annular gasket 16, under the mutual squeezing force between the external pipe and the connecting pipe 1, the annular gasket 16 slides into the fixing ring 7, and at the same time, the piston rod 15 slides in the connecting pipe 14, and the hydraulic oil in the connecting pipe 14 enters the interior of the connecting pipe 1, pushing the connecting ring 13 to drive the sealing ring 8 to slide outward. At this time, the sealing ring 8 is just stuck in the gap at the connection between the connecting pipe 1 and the external pipe, so that the interface between the connecting pipe 1 and the external pipe can be sealed by the annular gasket 16 and the sealing ring 8.

[0023] Working principle:

[0024] When in use, the connecting pipe 1 and the external pipe are threadedly connected together through the locking sleeve 2. When the end face of the external pipe contacts the annular gasket 16, the annular gasket 16 slides into the fixing ring 7 under the force of mutual compression between the external pipe and the connecting pipe 1. At the same time, the piston rod 15 slides in the connecting pipe 14, and the hydraulic oil in the connecting pipe 14 enters the interior of the connecting pipe 1, pushing the connecting ring 13 to drive the sealing ring 8 to slide outward. At this time, the sealing ring 8 is just stuck in the gap at the connection between the connecting pipe 1 and the external pipe. Therefore, the interface between the connecting pipe 1 and the external pipe can be sealed by the annular gasket 16 and the sealing ring 8, thereby preventing the fluid from overflowing from the pipe interface.

[0025] When fluid passes through the connecting pipe 1, under the impact of the fluid, the turbofan 3 drives the shaft 4 to rotate. When the shaft 4 rotates, the collar 10 rotates along the inner surface of the fixing frame 12. The compression spring 9 can buffer the impact force of the fluid on the surface of the turbofan 3, so that the shaft 4 can slide slightly relative to the collar 10. The sleeve 6 can make the two shafts 4 rotate together. The block 11 can make the shaft 4 slide relative to the shaft 4 while driving the collar 10 and the scraper 5 to rotate, thereby preventing the turbofan 3 from being damaged due to excessive fluid impact force, thereby extending the service life of the turbofan 3. When there is no fluid flowing in the connecting pipe 1, the turbofan 3 continues to rotate under the action of inertia. At this time, the scraper 5 rotates to scrape off the residual fluid attached to the inner wall of the connecting pipe 1, thereby preventing part of the fluid from remaining on the inner wall of the connecting pipe 1 and corroding the inner wall of the connecting pipe 1.

[0026] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
