Structure
Structure Characteristics
▪ According to the control system, it is divided into: ordinary accumulator type and accumulator type locking 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 block, mailbox and other components.
▪ Manual pump is used for system commissioning and valve opening and closing under special working conditions.
▪ The flow control valve is used to adjust the valve opening time.
▪ A quick closing time regulating valve is arranged on the transmission hydraulic cylinder, and the slow closing time adjusts the quick and slow closing angle regulating valve.
▪ In the system, the two accumulators are standby for each other to provide active power source for valve opening and closing.
▪ The valve shaft adopts long and short shaft structure.
▪ Generally, horizontal installation is adopted, and vertical installation can also be adopted according to user requirements.
▪ The hydraulic station, electric control box and valve body can be installed as a whole or separately. When vertical layout is adopted, they are installed separately.
▪ The control characteristics of electromagnetic directional valve in hydraulic system are generally positive action type.
▪ In horizontal installation, the transmission mechanism is generally installed in the forward direction; When limited by the site space, the reverse installation type can also be adopted according to the user’s requirements. (See below pictures)
