    product description

    KYP eccentric reducer rubber joints are improved on the basis of KXT rubber joints, which can solve the problems of different calibers and misalignment of pipes when connecting metal pipes. The eccentric reducer rubber joint can solve the problem of different calibers when metal pipes are connected, and at the same time, it has the effect of reducing vibration and noise, saving pipe 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 ring, and a metal flange. It has the characteristics of high pressure resistance, good elasticity, large displacement, balanced pipe deviation, good noise reduction effect, and convenient installation.

    Product advantages

    1. The eccentric big and small heads of the pipeline or pump valve are installed to prevent cavitation, and the big and small heads of the pump inlet should generally be installed flat. This is to prevent the gas in the pipeline from accumulating at the pump port, forming large bubbles into the pump cavity, and damaging the pump . Floor mounting is only possible in one case. That is the elbow that bends up 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 piping system. It is used for reducers with different diameters, and can achieve a straight connection between two pipes of different sizes.
    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.

    Performance characteristics

    First match the joint flange with the corresponding flange hole position of the corresponding pipeline, then pass the fixing screw through the flange hole and lock the nut with a wrench.
    1. This product can greatly reduce the vibration and noise of the pipeline system, and can fundamentally solve the problems of interface displacement, axial expansion and misalignment of various pipelines.
    2.According to different materials, it can be made into various varieties such as acid resistance, alkali resistance, corrosion resistance, oil resistance, high temperature resistance, etc., which can adapt to various media and environments.
    3. The material is polar rubber, good sealing, light weight, convenient installation and maintenance, long service life, but avoid contact with sharp metal equipment, so as not to puncture the sphere.
    4. If it is used overhead, it can be equipped with elastic brackets, and the bolts must be tightened diagonally during installation.
    5. If the pipeline pressure is too high, limit bolts should be used to connect the flanges at both ends together.
    6. The flange connection standard adopts GB / T9115.1-2000 standard. If other standards are used, it can be explained separately. The working pressure grade of this product is 0.6MPa and 1.0MPa.
    7. The normal suitable medium for rubber joints is ordinary water with a temperature of 0-60 ° C. Special media such as oil, acid and alkali, high temperature and other corrosive and hard textures should be made of rubber made of corresponding special materials. Connector, cannot be used blindly or universally.

    Classic Case
