Benefits
1. Diverse materials: The ball of the double sphere rubber joint is composed of the inner rubber layer, the reinforcing layer (multi-layer squeegee nylon cord fabric) and the outer rubber layer, and different rubber materials can be selected according to different media, such as natural rubber, styrene-butadiene rubber, butyl rubber, nitrile rubber, EPDM rubber, neoprene, silicone rubber, fluorine rubber, etc., which have the functions of heat resistance, acid resistance, alkali resistance, corrosion resistance, wear resistance, oil resistance, etc.
2. Low temperature resistance: Low temperature resistant fluoroelastomer and silicone rubber joints have high temperature resistance, oil resistance, chemical corrosion resistance, aging resistance and other properties, especially silicone rubber joints, whose working temperature can reach -100 °C, which is achieved by introducing methylphenyl siloxy links or diphenylsiloxy links into the molecular chain of methyl vinyl silicone rubber, thereby greatly reducing the crystallization temperature of the polymer and expanding the use temperature range.
3. Excellent physical properties: Double ball rubber joints have good sealing, convenient installation and maintenance, long service life, can avoid contact with sharp metal hose equipment, and prevent puncturing the ball. It also has good surface non-stick, air permeability, environmental safety, insulation, acid and alkali resistance, anti-aging, non-toxic, and uses 100% high-quality rubber raw materials, which meets environmental protection requirements.
4. Shock absorption, noise reduction and compensation displacement: Because of its good elasticity and shock absorption performance due to its rubber material, the double ball rubber joint can effectively reduce the vibration and noise in the pipeline system, and at the same time compensate for a certain displacement to avoid pipeline rupture caused by temperature changes, earthquakes and other reasons.
5. Wide range of applications: Because of its high elasticity, high air tightness, medium resistance and weather resistance, double ball rubber joints are widely used in various pipeline systems, such as building water supply and drainage, circulating water, ventilation and air conditioning, fire protection, paper industry, pharmaceutical industry, petrochemical equipment, ships, centrifugal water pumps, refrigeration units, centrifugal fans, etc.
