Description

Technical Field

[0001] This utility model relates to the field of drainage bend technology, specifically a sewage rubber bend. Background Technology

[0002] Sewage bends are key components in piping systems used to change the direction of sewage flow. Their main function is to connect sewage pipes with different orientations, allowing for 90° or specific angle turns to accommodate complex installation spaces. They also form a "water seal" structure, preventing odors, harmful gases (such as methane and hydrogen sulfide), and insects from flowing back into the room, thus ensuring environmental hygiene. Furthermore, the bend slows down sewage flow, reduces impurity buildup, lowers the risk of pipe blockage, and ensures the smooth discharge of sewage and wastewater (such as domestic sewage and industrial wastewater). Widely used in household, industrial, and municipal sewage systems, they offer multiple functions including flow guidance, odor prevention, and blockage prevention.

[0003] A relevant reference is Chinese utility model patent CN219300182U, which discloses a drain bend that facilitates cleaning. This drain bend includes a bend body with an inlet pipe fixedly connected to its left end and an outlet pipe fixedly connected to its right end. A drain outlet is located at the bottom of the bend body, and a drain pipe is connected to the bottom of the drain outlet. A baffle is fixedly installed inside the drain pipe. A filter screen is installed inside the right side of the bend body. An air bladder is located on the outer side of the bend body at the top of the filter screen. The air bladder is connected to the bend body via an air pipe. The top of the drain pipe is fitted against the inner wall of the drain outlet, and a sealing rubber gasket is fitted at the joint between the drain pipe and the drain outlet. When there is a large amount of impurities and debris in the bend, pulling the pull rope can separate the drain pipe from the drain outlet, allowing the debris to be discharged and facilitating cleaning.

[0004] Currently, the sewage discharge rubber elbows in use still have the following problems: In practical applications, the angles of existing sewage rubber elbows are mostly fixed, making it impossible to flexibly adjust them according to the actual installation angle of the pipeline on site. When there is a deviation in the pipeline angle or a temporary change in the turning angle is required, the elbow with the corresponding angle must be replaced, resulting in poor installation adaptability. Furthermore, sewage media often contain corrosive components such as acids, alkalis, oil, impurities, and microorganisms, and are exposed to outdoor or humid environments for a long time. Existing rubber elbows are prone to corrosion, swelling, and deformation. At the same time, they are prone to aging, hardening, and cracking under the influence of ultraviolet rays and temperature changes, leading to sealing failure and sewage leakage. This not only shortens the service life but also easily causes environmental pollution and frequent pipeline maintenance, making it difficult to meet the actual needs of efficient, stable, and long-term operation of sewage systems. Utility Model Content

[0005] The purpose of this utility model is to provide a sewage discharge rubber bend to solve the problems mentioned in the background art, such as the inability of rubber bends to flexibly adjust their angle according to the pipeline route and the brittleness and cracking of rubber bends.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: This utility model provides a sewage discharge rubber bend, including a bend body, an installation ring, an adjusting ring mechanism, and an inner tube mechanism. The installation ring is installed at both ends of the bend body, and the adjusting ring mechanism is sleeved on the outside of the bend of the bend body. The bend body is provided with a bent inner tube mechanism. The bend body includes an internal plasticizing layer, and an anti-corrosion layer is provided on one side of the plasticizing layer. The inner wall of the bend body is coated with a hardening layer. The adjusting ring mechanism includes collars at both ends, with gear teeth annularly mounted on the surface of the collars, and a plug rod is transversely mounted between the two sets of collars. A flexible hose is provided between the adjusting ring mechanism and the collars, and the flexible hose is connected to the bent pipe body.

[0007] Preferably, the plasticizing layer is made of phthalate DOP material in a thick coating, the anti-corrosion layer is made of a mixture of nitrile rubber and an antioxidant, and the hardening layer is made of a mixture of carbon black and silica.

[0008] Preferably, the surface of the adjusting ring mechanism is provided with a toothed groove, and the insert rod is inserted into the interior of the adjusting ring mechanism and connected to the collar.

[0009] Preferably, the bent tube body is folded using a flexible hose, and the gear teeth are located inside the tooth groove.

[0010] Preferably, the inner tube mechanism is provided with filter screens at both ends, and a side block is fixedly installed on one side of the edge of the filter screen, and the surface of the side block is provided with a groove.

[0011] Preferably, the surface of the filter screen has a plurality of circular holes, and the filter screen is located inside the mounting ring.

[0012] Preferably, the side block is installed on the inner wall edge of the mounting ring, and both the inner tube mechanism and the bent tube body are made of rubber material.

[0013] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects: 1. When the sewage rubber elbow is installed, the plastic layer inside the elbow body improves the flexibility and deformation resistance of the entire elbow during use, reducing the occurrence of cracking and damage. The anti-corrosion material inside the anti-corrosion layer and hardening layer can form a protective structure inside the elbow, isolating it from oil, acid and alkali and other corrosive components in the sewage, extending the overall service life of the equipment. The filter screen can filter impurities in the sewage, reducing the frequency of internal cleaning and maintenance of the elbow. 2. When the sewage rubber elbow is installed, a flexible hose is connected to the elbow body. The flexible hose allows the elbow body to freely adjust its turning angle according to the pipeline direction, which can greatly improve the adaptability of the elbow during installation. At the same time, the design of the plug rod can fix both ends of the flexible hose, so that sewage flows according to the direction of the elbow, enhancing the versatility and practicality of the product and ensuring the stable operation of the sewage system.
