Hot sale Eccentric reducer type flexible rubber expansion joint
Introduction of reducer type rubber expansion joint:
The utility model relates to a flexible eccentric eccentric rubber joint, which can solve the problem of different caliber when the metal pipe is connected,and has the function of shock absorption and noise reduction, and can save the installation parts of the pipeline and save the cost. The utility model is composed of an inner rubber layer, a fabric reinforcing layer, a middle rubber layer, an outer rubber layer, an end reinforcement, a metal ring or a steel wire ring, a metal flange or a parallel movable joint.
With unique design, simple structure and good sealing performance, rubber joint completely solve the pipeline displacement problems caused by thermal expansion and contraction, as well as mechanical vibration.
Reducer rubber bellows expansion joint is made up of fabric reinforced rubber main body and metal flange or wire buckle joint, which is used for vibration reduction, noise reduction and displacement compensation of pipeline. It is related to: JGD single sphere rubber joint, jgd-a double sphere, jgd-b wire buckle connection double sphere, etc., it is A high elasticity, medium resistance and weather resistance pipe joint. It is also known as rubber soft joint, shock absorber, pipe shock absorber, shock absorber throat, size head, variable-diameter joint, but the name is different, but refers to reducer rubber bellows expansion joint.
