Description

Technical Field

[0001] The present invention relates to the technical field of flushing pipe equipment, and specifically relates to a novel flushing pipe device. Background Art

[0002] One of the components of a faucet; it connects the gooseneck pipe and the central pipe to form a channel for drilling fluid. There is a flange at the upper end of the flushing pipe, which is connected to the faucet housing and the gooseneck pipe and sealed with a gasket to prevent leakage. Its lower end is inserted into the central pipe or docked at the upper end of the central pipe, and the gap between the flushing pipe and the central pipe is filled with packing (flushing pipe packing) for sealing; during drilling, the central pipe rotates, and the flushing pipe packing (rotating with the central pipe) generates relative movement with the flushing pipe.

[0003] The existing flushing pipe structure has strong integrity, which increases the overall processing difficulty and raises the processing cost. At the same time, when in use, the biasing spring is arranged outside the flushing pipe structure. In this way, during long-term use, the external environment is extremely likely to affect the biasing spring on the outside, affecting the service life of the entire flushing pipe structure. Therefore, there is an urgent need for a device to solve the above problems. Summary of the Invention

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0017] Please refer to Figure 1 , the present invention provides a technical solution: a new type of pipe flushing device, including an upper union 1, a lower union 2, a bolt 11 and a positioning pin 9. The upper union 1 is fixed under the gooseneck pipe through a connecting flange. A floating support seat 3 is fixed to the lower end of the upper union 1 through the bolt 11. A sealing ring 15 for conveniently sealing the position between the upper union 1 and the floating support seat 3 is inlaid between the upper union 1 and the floating support seat 3. The sealing ring 15 is movably inlaid inside the upper union 1. A first O-ring 14 is movably inlaid at the top of the upper union 1 to conveniently seal the position between the upper union 1 and the gooseneck pipe. A floating cylinder 4 slides on the outside of the floating support seat 3. There is an anti-rotation structure on the floating cylinder 4 to prevent relative rotation between the floating support seat 3 and the floating cylinder 4. The anti-rotation structure is that there are protruding strips on the inside of the floating cylinder 4 movably inlaid on the outer wall of the floating support seat 3, so as to prevent relative rotation between the floating support seat 3 and the floating cylinder 4. A lower flange 5 is welded and fixed to the bottom end of the floating cylinder 4. A static ring 7 is fixed to the bottom end of the floating cylinder 4 through the lower flange 5. A second O-ring 16 for sealing the position between the static ring 7 and the floating cylinder 4 is inlaid between the static ring 7 and the floating cylinder 4. The second O-ring 16 is movably inlaid at the bottom end of the floating cylinder 4. A moving ring 8 is fixed to the top end of the lower union 2. The top end of the moving ring 8 is closely attached to the bottom end of the static ring 7. The positioning pin 9 is fixedly inlaid at the top end of the lower union 2. The second O-ring 16 is inlaid between the moving ring 8 and the lower union 2 to conveniently seal the position between the moving ring 8 and the lower union 2. The first O-ring 14 is movably inlaid at the bottom end of the lower union 2. A lifting device 6 is sleeved on the outside of the floating support seat 3 through a thread. A guiding belt 13 is inlaid and fixed inside the floating cylinder 4. A U-shaped seal 12 is inlaid inside the floating cylinder 4. A spring 10 is located between the floating support seat 3 and the floating cylinder 4. The spring 10 is sleeved on the outside of the floating support seat 3 and the spring 10 is located inside the lifting device 6, so as to prevent the external environment from affecting the spring 10 and improve the service life of the spring 10. At the same time, the whole device is connected through bolts 11, connecting flanges, threads, etc., so that the overall device has strong dispersibility. When processing, each component is processed one by one, and then spliced and combined. Compared with the overall processing, processing the components separately reduces the processing difficulty, thereby improving the processing efficiency and reducing the processing cost.

[0018] Working principle: Since the spring 10 is located inside the prompting device 6, it prevents the external environment from affecting the spring 10, prolongs the service life of the spring 10. At the same time, the whole device is connected by bolts 11, connecting flanges, threads, etc., making the overall device highly dispersive. During processing, each component is processed one by one and then spliced and combined. Compared with integral processing, processing by separate components reduces the processing difficulty, thereby improving the processing efficiency, reducing the processing cost, and when in use, the elastic force of the spring 10 keeps the moving ring 8 and the static ring 7 in a tightly fitting state.
