    product description

    KYP-F eccentric reducer rubber joint is improved on the basis of KXT rubber joint, which can solve the problem of different calibers and eccentricity of pipes when connecting metal pipes. The eccentric reducer rubber joint has the effect of reducing vibration and noise, saving pipeline installation parts and cost. It consists of an inner rubber layer, a fabric reinforcement layer, a middle rubber layer, an outer rubber layer, an end-reinforced metal ring or steel wire ring, and then connected to a metal flange. It has the characteristics of high pressure resistance, good elasticity, large displacement, balanced pipeline deviation, vibration and noise reduction, good noise reduction effect, and convenient installation.
    Eccentric reducer rubber joints can be widely used in water supply and drainage, circulating water, HVAC, fire protection, papermaking, pharmaceuticals, petrochemicals, ships, pumps, compressors, fans and other pipe systems. General type: suitable for transporting water with a temperature of -20 ~ 115 ° C and an acid or alkali solution with a concentration of less than 10%. There are also some special rubber materials required for special pipelines: such as oil resistance, high temperature resistance, ozone resistance, wear resistance, or other forms of chemical corrosion.

    Product advantages

    1. Pipe-pump installation eccentric head: It is used to prevent cavitation, and the head of the pump inlet should generally be installed flat. This is to prevent the gas phase in the pipeline from accumulating at the pump port, forming large bubbles into the pump cavity, and damaging the pump. . Only one case can be installed in the floor. That is the elbow that is bent upwards directly behind the big and small heads. In this case, it is impossible for the gas phase to accumulate.
    2. Pump-pipe installation reducer: There is a difference between the pump outlet and the external pipe system. It is used for reducers with different diameters to achieve a straight connection between two pipes of different sizes and to achieve pipe diameter reduction.

    Performance characteristics

    The axial displacement of an eccentric reducer rubber joint is the elongation or compression of the rubber joint in the direction of fluid flow (that is, the direction of the central axis).
    The lateral displacement of the eccentric reducer rubber joint is the displacement of the rubber joint in a direction perpendicular to the fluid direction, that is, the direction of the central axis.
    The angular displacement of the eccentric reducer rubber joint is the sum of the angle between the vertical centerline of the two end faces of the rubber joint and the original central axis.

    Classic Case

    Cooperation project of KYP-F eccentric reducer rubber joint in Zhengzhou Huancheng Ecological Water System Circulation Project

    On the 11th, the city's urban ecological water system circulation project started at the intersection of the South Fourth Ring Road and the Shibali River. As the main supplier of KYP-F eccentric reducer rubber joints, Gongyi Xinli can effectively reduce the vibration of the pipeline, thereby ensuring the long-term operation of the pipeline.
    It is understood that the Zhengzhou Huancheng Ecological Water System Circulation Project uses Niukouyu to divert yellow water as a source of water. By constructing two-stage pumping stations and water pipelines in Putianze (to be constructed) and Chaohe River, the water is sequentially brought to Huama. The upper reaches of rivers, such as ditch, Baishi Guantan ditch, Chaohe River, Shili River, Shiba River, Xiong'er River, Jinshui River, transport ecological water for it. The project is designed to have a total flow of 7 cubic meters per second. The pipeline runs from the water intake of Putianze Pumping Station to the Jinshuihe watershed, with a total length of 51 kilometers and a branch line of approximately 11 kilometers. A total of 9 water outlets are set along the way. The total investment of the project is about 780 million yuan, which is the city's water ecological civilization construction project in 2015. After completion, it will provide economic and reliable water sources for our ecological water system, effectively alleviate the shortage of water resources in our city, and curb the trend of groundwater over-extraction to a certain extent. The project will also significantly improve the ecological landscape environment of the rivers in the urban area, and also be beneficial to the healthy development of the city's water ecology.
    As a professional manufacturer of eccentric reducer rubber joints, Xinli Pipeline has been dedicated to the pipeline industry for 30 years. It has rich experience in the production and installation of eccentric reducer rubber joints. It adopts very good production technology and advanced production equipment to ensure the eccentric difference. The quality of the rubber joint products, and every eccentric reducer rubber joint products produced by our company have undergone strict inspection and testing before leaving the factory. The product quality is worth your trust.
