Abstract
Description
Technical Field
[0001] The invention relates to the technical field of toilet sewer drainage, in particular to a large-flow plastic pipe drainage system with high spiral ribs. Background Art
[0002] Plastic pipe is a commonly used pipe for building drainage. However, due to the smooth inner wall and low friction resistance of plastic pipe, when it is used for toilet or sewer drainage, the water flow velocity is high. When the flow rate is slightly larger, it is easy to form a water plug flow (water plug flow: refers to the drainage riser used for gravity drainage. When the flow rate is too large, the thickness of the water film attached to the pipe wall is too large or the water flow is affected by the structure, the water flow forms a central water mass and falls in the pipe, forming a mass plug-shaped water flow falling in the pipe. In this water flow state, the water flow is less affected by the friction resistance of the pipe wall, and the downward speed drops quickly, forming an accelerated flow under the action of gravity. It causes severe pressure fluctuations and loud water flow noise, which can easily damage the water seal of the bathroom floor drain and cause odor.), resulting in large pressure fluctuations in the pipe and odor in the bathroom. This shortcoming limits the improvement of the drainage capacity of plastic pipes. In order to solve this problem, a new type of internal spiral plastic drainage pipe has been developed in the past decade and has been widely promoted and applied.
[0003] However, during actual use and drainage capacity testing, when the drainage volume increases, large pressure fluctuations and vibration noise are generated in the drainage pipe. In severe cases, water plug flow occurs, affecting the connection strength of multi-section pipes and connectors. In public toilets or sewers, toilet paper may be discharged in the pipe. If the toilet paper in the pipe is not discharged in time, it will accumulate and clog the pipe, affecting the drainage of the pipe.
[0004] Therefore, we provide a large flow plastic pipe drainage system with high spiral ribs to solve the above problems. Summary of the invention

[0007] Furthermore, each group of the serrations is distributed in an arc shape on the spiral rib, and multiple groups of the serrations are distributed in a circular array in the drainage cavity of the pipe.
[0008] Furthermore, a value of a horizontal arc distance A of the sawtooth portion is equal to a value of a horizontal arc distance B of the smooth portion.
[0009] Furthermore, the height of the spiral ribs is 4 to 15 mm.

[0011] Furthermore, the sealing assembly includes a pipe fitting, an inner annular bulge is provided in the middle of the inner wall of the pipe fitting, two first annular limiting grooves and a second annular limiting groove are symmetrically provided on the inner wall of the pipe fitting, and both ends of the pipe fitting are provided with a platform convex edge, and the inner diameter of the platform convex edge is smaller than the inner diameter of the pipe fitting.

[0013] Furthermore, one end of the tube is inserted into the large surrounding rubber ring, the end edge of the tube contacts the annular flat block to form a first leak-proofing, the outer wall of the tube cooperates with the sealing ring to form a second leak-proofing, and the outer wall of the tube cooperates with the inverted V-ring to form a third leak-proofing; the large surrounding rubber ring is placed in the pipe fitting, the first annular limiting protrusion cooperates with the first annular limiting groove to form a fourth leak-proofing, and the second annular limiting protrusion cooperates with the second annular limiting groove to form a fifth leak-proofing.
[0014] Furthermore, the inner diameter of the convex edge of the pipe fitting is smaller than the outer diameter of the large surrounding rubber ring, and the angle between the inverted V-ring and the inner wall of the large surrounding rubber ring is in the range of 30° to 60°.
[0015] Furthermore, the inner diameter of the annular flat block is 1 mm smaller than the inner diameter of the tube, one end of the telescopic ring of the large surrounding rubber ring contacts the inner ring bulge of the tube to form a sixth leak-proof feature, the telescopic height of the telescopic ring is 2% to 5% of the tube diameter, and the bulge height of the sealing ring is between 0.3 mm and 0.6 mm.
[0016] Furthermore, continuous irregular serrations are distributed on the top of the spiral ribs. The continuous irregular serrations act as saw blades to cut up excrement and the like in the pipe, thereby reducing the risk of pipe blockage and ensuring the large-flow drainage capacity of the pipe.
[0017] (III) Beneficial effects Compared with the prior art, the large-flow plastic pipe drainage system with high spiral ribs provided by the present invention has the following beneficial effects: 1. The connection between the root of the spiral rib and the pipe of the present invention is an arc transition structure, and the curvature is greatly reduced (the radius of curvature is increased). According to the theory of fluid wall attachment effect, when the water in the pipe falls along the pipe wall, the water is adsorbed on the pipe wall and will not leave, forming a good wall-attached water film flow state, avoiding the situation where the water moves toward the center of the vertical pipe to produce water plug flow, reducing the fluctuation of the pressure in the pipe, increasing the drainage flow within a certain pressure fluctuation range, and avoiding the alternating impact of the water on the pipe wall, so that the pipeline vibration and drainage noise are greatly reduced. Furthermore, the adsorbed water flow is affected by the friction resistance of the pipe wall, and the falling speed is greatly reduced, avoiding the damage of the water seal and preventing the floor drain from returning odor; Since the falling water flow is adsorbed on the pipe wall, the effect of the friction resistance of the pipe wall on the water flow is increased. At the same time, the spiral curved water flow falling path extends the water flow movement length per unit falling height, so that the falling speed of the water flow is further reduced, thereby reducing water pressure fluctuations and improving drainage capacity; it can better reduce the falling speed of the water flow, reduce noise, and avoid odor in the bathroom; and the different designs of the intermittent serrations and continuous serrations on the spiral ribs can cut the toilet paper or excrement in the pipe, avoid the situation where toilet paper blocks the water pipe, and further improve the smooth drainage capacity of the plastic pipe.
[0018] 2. In the pipe of the present invention, one end of the pipe is inserted into the large surrounding rubber ring, and the end edge of the pipe contacts the annular flat block to form the first leak-proof function. The annular flat block is the first line of protection, which effectively blocks water from entering the joint surface of the pipe and the large surrounding rubber ring. The inner diameter of the flat block is 1mm smaller than the inner diameter of the pipe. The outer wall of the pipe cooperates with the sealing ring to form the second leak-proof function. The sealing ring is the second line of protection. Experiments have shown that when the water flow generates a full pipe pressure of 0.05Mpa, water enters the joint surface of the rubber ring and the pipe through the annular flat block. At this time, the protection of the sealing ring effectively enhances the pressure-bearing capacity and effectively blocks water from entering the second half of the sealing ring, thereby achieving a good blocking and leak-proof effect.
[0019] 3. The outer wall of the pipe of the present invention cooperates with the inverted V-ring to form a third leak-proof feature, and the inverted V-ring is the third line of protection. When the water flow pressure is greater than the sealing pressure of the annular flat baffle and the sealing ring, through the inverted V-shaped design, the greater the water pressure, the tighter the inverted V-ring fits the pipe, further improving the sealing performance of the large surrounding rubber ring and the pipe fitting; the large surrounding rubber ring is placed in the pipe fitting, and the first annular limiting convex ring cooperates with the first annular limiting groove to form a fourth leak-proof feature. The first annular limiting convex ring is the fourth line of protection to prevent water from entering the joint surface between the large surrounding rubber ring and the inner wall of the pipe fitting when the water flow generates a full pipe pressure of 0.2Mpa.
[0020] 4. The second annular limiting convex ring cooperates with the second annular limiting groove to form the fifth leak-proof feature. The second annular limiting convex ring is the fifth line of protection, which further prevents water from leaking to the outside from the joint surface between the large surrounding rubber ring and the inner wall of the pipe fitting; one end of the expansion ring of the large surrounding rubber ring contacts the inner convex ring of the pipe fitting to form the sixth leak-proof feature. The expansion height of the expansion ring is 2% to 5% of the pipe diameter. When the pipe expands and contracts due to alternating temperatures, the expansion ring automatically compensates to ensure the anti-detachment and anti-leakage performance of the assembly.
[0021] 5. The components of the present invention are composed of pipes, pipe fittings, and large surrounding rubber rings. The large surrounding rubber rings and pipe fittings are formed by one-time integral injection molding. The pipes are inserted into the integrally formed pressure-bearing pipe fittings. When the pipe is fully drained, the large surrounding rubber rings provide six levels of water leakage protection to ensure that the interface of the assembly is leak-proof and produces a pressure bearing capacity of not less than 0.6Mpa. At the same time, a telescopic ring is provided. When the pipe of the pipe expands and contracts when the temperature alternates between hot and cold, the telescopic ring automatically compensates to ensure the anti-detachment and anti-leakage performance of the assembly. The connection method of the present invention has stronger pressure bearing capacity, a static pressure of 0.6Mpa, good anti-detachment ability, high construction efficiency, and low cost.

[0034] This embodiment provides a large flow plastic pipe drainage system with high spiral ribs: The connection between the root of the spiral rib 101 of the present invention and the pipe 1 is an arc transition structure, and the curvature is greatly reduced (the radius of curvature is increased). According to the theory of fluid wall attachment effect, when the water in the pipe falls along the pipe wall, the water is adsorbed on the pipe wall and will not leave, forming a good wall-attached water film flow state, avoiding the situation where the water flows toward the center of the vertical pipe to produce water plug flow, reducing the fluctuation of the pressure in the pipe, increasing the drainage flow within a certain pressure fluctuation range, and avoiding the alternating impact of the water flow on the pipe wall, so that the pipeline vibration and drainage noise are greatly reduced. Furthermore, the adsorbed water flow is affected by the friction resistance of the pipe wall, and the falling speed is greatly reduced, avoiding the damage to the water seal and preventing the floor drain from returning odor; Since the falling water flow is adsorbed on the pipe wall, the effect of the friction resistance of the pipe wall on the water flow is increased. At the same time, the spiral curve-shaped water flow falling path prolongs the water flow movement length per unit falling height, so that the falling speed of the water flow is further reduced, thereby achieving the effect of reducing water pressure fluctuations and improving drainage capacity; the falling speed of the water flow is better reduced, noise is reduced, and odor in the bathroom is avoided; and the design of the serrated portion 102 can have a shredding effect on the toilet paper in the pipe, avoiding the situation where the toilet paper blocks the water pipe, and further improving the smooth drainage capacity of the plastic pipe; The drainage system of the present invention is composed of a pipe 1, a pipe fitting 2, and a large surrounding rubber ring 3. The large surrounding rubber ring 3 and the pipe fitting 2 are formed by one-time integral injection molding; the pipe 1 is inserted into the integrally formed pressure-bearing pipe fitting 2. When the pipe is fully drained, the large surrounding rubber ring 3 performs six levels of water leakage protection to ensure that the sealing assembly interface does not leak and generates a pressure bearing capacity of not less than 0.6Mpa. The outer wall of the pipe 1 of the present invention cooperates with the inverted V-ring 303 to form a third leak-proof, and the inverted V-ring 303 is the third line of protection. When the water flow pressure is greater than the sealing pressure of the annular flat block 305 and the sealing ring 304, through the inverted V-shaped design, the greater the water pressure, the tighter the inverted V-ring 303 fits the pipe 1, further improving the sealing performance of the large surrounding rubber ring 3 and the pipe fitting 2; the large surrounding rubber ring 3 is placed in the pipe fitting 2, and the first annular limiting convex ring 301 cooperates with the first annular limiting groove 202 to form a fourth leak-proof to prevent water from entering the joint surface of the large surrounding rubber ring 3 and the inner wall of the pipe fitting 2 when the water flow generates a full pipe pressure of 0.2Mpa; at the same time, a telescopic ring 306 is provided. When the pipe of the pipe 1 expands and contracts when the temperature alternates between hot and cold, the telescopic ring 306 automatically compensates to ensure the anti-detachment and anti-leakage performance of the assembly; the connection method of the present invention has stronger pressure bearing capacity, a static pressure of 0.6Mpa, good anti-detachment ability, high construction efficiency, low cost and the like.
