1.Product details.

Name:Ductile iron Eccentric half ball valve used in water plant

Ductile Iron Eccentric Half Ball Valve Used in Water Plant
01. Description

Eccentric ball valve is the metal ball crown and fixed on the eccentric shaft, eccentric crankshaft rotation, opening and closing of the valve. Contact with the metal ball crown sealing surface of metal seated in axial and radial floating, to compensate the mismatch error of spherical cap and valve seat. The structure of simple, reliable and effective way of seal to make it not but can be an advantage to replace other valves, and can be applied to they do not use the system, such as power plants, metallurgy, cement, paper and other industries of coal powder, ash, such as pulp material pipeline sealing surface can adopt different sealing material to apply various working environment.

03. Features

001. Eccentric crankshaft and hemispherical structure
Using the eccentric principle, namely the valve port different heart center and crankshaft principle. In the process of closing, the valve ball crown gradually to the seat. At the moment close to achieve reliable seal, avoid the valve opening and closing process remain the state of friction pair of seal, valve ball for hemispherical. Open the valve ball crown hidden in valve cavity, from medium appropriate sealing wash set; At the same time to ensure the valve full flow channel circulation, the maximum eye degree to reduce the energy loss, head loss is almost zero. 
002. Small installation space
The installation height of the valve is smaller than the steel valve of the same specification, similar to the butterfly valve, and the structure length is smaller than the standard ball valve and similar to the butterfly valve. Besides, the installation is not limited by the direction of water flow and the installation space, and can be installed at any Angle; Online push repair, maintenance. Do not need to be removed from the pipeline. 
003. Double seal
A fluororubber seal ring is sintered on the stainless steel crown with special process, which has two kinds of seals, soft and hard. Even if the soft seal is worn or damaged, a reliable seal can be achieved. Depending on the circumstances of the eccentric half - ball valve this design will be applied to the seat. 
004. Labor-saving bearing
The upper and lower stem is provided with thrust suction bearing. The composite Shaft Sleeve reduces the transmission torque and has prominent advantages in the choice of electric actuator.

07.Operating principle

Half of an eccentric valve is to use the oil pump of high pressure oil push the movement of the oil cylinder piston, the crank transmission mechanism to drive the valve rod rotation. Open the door. When the need to close the cock. Press button where the valve, solenoid valve to be open drain circuits, door plank under the energy storage type hydraulic control power, closed after the first fast slow procedure, achieve the goal of energy storage type hydraulic control.
