Structure Characteristics
▪ According to the control system, it is divided into: heavy hammer locking type, heavy hammer automatic pressure maintaining type.
▪ It is mainly composed of valve body, transmission mechanism, hydraulic station and electric control box.
▪ The valve body is composed of valve body, disc, valve shaft/stem, sealing components and other parts. The transmission mechanism is mainly composed of hydraulic cylinder, rocker arm, supporting side plate, heavy hammer, lever, locking cylinder and other connecting and transmission parts. It is the main actuator for hydraulic power to open and close the valve.
▪ The hydraulic station includes oil pump unit, manual pump accumulator, solenoid valve, overflow valve, flow control valve, stop valve, hydraulic manifold, oil tank and other parts. The valve body adopts horizontal structure. The valve shaft adopts both long and short shaft structures.
▪ In the heavy hammer automatic pressure maintaining system, the accumulator is used to compensate the system pressure.
▪ In the heavy hammer pressure maintaining locking system, the accumulator is used to compensate the system pressure and unlock the locking cylinder.
▪ The transmission hydraulic cylinder is provided with a fast closing time regulating valve, a slow closing time regulating valve and a fast and slow closing angle regulating valve.
▪ Manual pump is used for system commissioning and valve opening and closing under special working conditions.
▪ The hydraulic station, electric control box and valve body can be installed as a whole or separately. Generally, it is an integral installation.
▪ The flow control valve is used to adjust the valve opening time.
▪ The control characteristics of electromagnetic directional valve in hydraulic system are generally positive action type.
