    What is a double ball rubber valve?

    Double ball rubber joint refers to a live joint and two rubber expansion joint composed of rubber shock absorber equipment, mainly used for a variety of pipeline shock absorber, can reduce the vibration of the pipeline so that the normal and stable operation of the pipeline. In the national standard of rubber joint naming rules, test methods, materials and other aspects of the requirements. In the standard is called double ball rubber soft connection, double ball rubber shock absorber throat and other names. According to the type used, it can be divided into ordinary type and special type. Different types of rubber joints are mainly determined by the material of synthetic rubber. Special types can be achieved according to the material of improved rubber. Manufacturers can carry out rubber prescriptions according to the provisions of the standard and manufacture synthetic rubber.

    Advantages of the double ball rubber valve:
    1.High strength protection performance
    The rubber soft joint has strong compressive resistance, impact resistance, and flexible friction coefficients, shock absorption and anti-skid, with strong protective performance.
    2.Applicable to different occasions
    The rubber soft joint has good climate resistance and temperature resistance, and the rubber plate also has good UV resistance characteristics, which can meet the needs of different places.
    3.Safety and environmental protection
    Rubber pads are safe, non-toxic, do not have to worry about negative harm to the human body, and will not breed microbes, more healthy.
    4.Stainless steel flange
    Stainless steel material with high strength anti-corrosion, rust prevention, we ensure that each flange spectrum acceptance.
    5.Cotton nylon cord skeleton
    The nylon skeleton is the main component of the rubber soft joint, and the density and number of layers determine the tolerance pressure.
