Joint rubber duckbill valves
1. High pressure, good elasticity
2. Reduce the noise effect is good, easy installation
3. Used for water supply and drainage, circulating water and so on
In a flexible rubber joint is made of fabric reinforced rubber parts and flat form union, slip-on metal flanged or threaded pipe flanges, used for pipeline vibration noise reduction, compensation displacement connector. Is a kind of high elasticity, high air tightness, medium resistance and weather resistance of the pipe joint. Concentric with diameter, concentric reducer and eccentric reducer. Double spheres in a flexible rubber joint structure is divided into: Single ball, double ball, bend the ball.
Can be curved in the form of flexible rubber joint, flange, screw lines connected, threaded pipe flange connections. Because in a flexible rubber joint double ball pressure points: 0.25 MPa, 0.6 MPa, 1.0 MPa, 1.6 MPa, 2.5 MPa grade five.
Curved bending double sphere rubber joint performance characteristics: 1, small size, light weight, good elasticity, easy installation and maintenance. 2, the installation can cause transverse, axial, angular displacement, pipe impassability heart, flange unparallel. 3, the work can reduce the structure transfer noise, vibration absorbing ability.
In a range of flexible rubber joint use: Because it has good comprehensive performance, so it is widely used in chemical industry, building, give water, drainage, oil, light and heavy industry, refrigeration, sanitary, plumbing, fire protection, electric power and so on basic engineering.
