1. The valve can achieve two-way zero leakage(forward and backward direction to withstand 1.1 times the rated nominal pressure zero leakage). Using eccentric, floating ball valve board seat. The installation of the rotation center and the seat of the valve core center one eccentricity between the delta(pictured), all closed, valve if it shut down a tiny angle, valve seat sealing surface and the spherical valve core can produce interference, which will produce a lot of extrusion between sealing surface, forming high sealing pressure ratio, implementing strict sealing pressure condition. Valve of the eccentricity of the delta valve is closely theoretical calculation( hydraulic calculation, the bending stiffness and torsional rigidity calculation of eccentric shaft, spherical cap and valve seat deformation calculation, etc.) to meet the requirements of two-way valve seal.
2. The sealing surface does not wear, jam or pull. Due to eccentric ball structure and eccentricity valves give full consideration to the hydraulic characteristics of the fluid and material mechanical properties, when the valve is opened, the valve core is turning a small angle, the valve core and valve seat sealing surface out of. when the valve is closed, the spool and seat contact each other at the last minute to reduce wear Seal are axial float, float distance compensating valve plate installed in hydrostatic pressure, temperature stress, stress under the action of deformation, so the seal between the sealing pressure ratio is basically a constant value, sealing surface does not produce occlusion and strain.
3. The sealing surface has self-purification ability. Dirt, weed, sticks and wire, can be cut off by valve closing seat design.
