double flange Eccentric reducer rubber joint

  The eccentric reducer rubber joint can solve the problem of different diameters in connection of metal pipes, reduce vibration and noise, and save installation parts and costs. It is composed of inner rubber layer, fabric reinforcement layer, middle rubber layer, outer rubber layer, end reinforcement metal ring or steel ring, metal flange or parallel live joint.

Features and USES:

  With high pressure, good elasticity, large displacement, balance pipe deviation, absorb vibration and reduce noise effect is good, installation is convenient wait for a characteristic, eccentric reducing rubber joint can be widely used in water supply and drainage, water, hvac, fire protection, paper making, pharmacy, petroleum chemical industry, ship, water pump, compressor, fan and other pipe system.

Classification：

  Generic class: suitable for conveying temperature for 15 ~ 80 ℃ water, acid or alkali solution solution concentration below 10%.

 Special class: suitable for special performance requirements, such as oil resistance, plug resistance, ozone resistance, wear resistance or chemical corrosion resistance.

Heat-resistant class: suitable for conveying water temperature higher than 80 ℃.

Performance and function:

  1. Pipe-pump installation eccentric size head: it is used to prevent cavitation, and the size head at the pump inlet should be installed flat on the top, which prevents the gas phase in the pipeline from accumulating in the pump mouth, forming large bubbles into the pump chamber and damaging the pump. Only in one case can the flat bottom be installed. That is the size of the head directly behind the bending up the elbow. The gas phase cannot accumulate under these conditions.

  2. Pump - pipe installation concentric reducer: there is a difference between the DN at the pump outlet and the external pipe system. It is used for concentric reducer, which can realize linear connection of two pipes with different sizes and pipe fitting for pipe diameter reduction.

  Axial displacement of eccentric reducer rubber joint is the elongation or compression of rubber joint in the direction of fluid flow (that is, the direction of the central axis).

  The lateral displacement of the rubber joint with eccentric reducer is: the displacement of the rubber joint in the direction perpendicular to the direction of the fluid, that is, the direction of the central axis.

  The angular displacement of the eccentric rubber reducer is the sum of the included angles of the vertical center line and the original central axis of the two end faces of the rubber reducer.
