Hydraulic station for hydraulic control slow closing check butterfly valve

working process

The reserved closing energy of heavy hammer hydraulic control slow closing check butterfly valve is heavy hammer potential energy, which is divided into heavy hammer automatic pressure holding hydraulic control slow closing check valve and locking heavy hammer automatic pressure holding hydraulic control slow closing check butterfly valve. The main operating conditions include centrifugal pump operating conditions, axial flow pump operating conditions, and turbine operating conditions.

Under the condition of opening the valve, the centrifugal pump should be started first, and the valve should be opened after extending the predetermined time. Under the condition of opening the valve, the pump and valve should be opened simultaneously, or the valve should be opened to a certain angle before starting the pump. Open the bypass valve to level the lateral pressure first, then open the valve, and finally start the turbine. Various working conditions generally require the valve to be closed simultaneously with shutdown or power outage.

Manual pumps are mainly used for system debugging. In the absence of electricity or when the oil pump cannot function properly, shaking the manual pump can also complete the valve opening and system pressure maintenance. Open the normally closed shut-off valve, and under the action of the hammer's potential energy and hydrodynamic torque, the connecting rod drives the butterfly plate to rotate and close the valve.

Result Description

The heavy hammer hydraulic control slow closing check butterfly valve is mainly divided into six parts: valve, body, transmission system, hydraulic station, heavy hammer energy storage mechanism, locking device, electrical control system, etc.

Remote and automated operations now available

As an independent hydraulic device, the hydraulic station supplies oil according to the requirements of the driving device (main engine) and controls the direction, pressure, and flow rate of the oil flow. It is suitable for various hydraulic machinery where the host and hydraulic device can be separated. After purchase, users only need to connect the hydraulic station to the actuator (oil cylinder and oil motor) on the host through oil pipes, and the hydraulic machinery can achieve various specified actions and work cycles. This enables the hydraulic control slow closing check butterfly valve to be operated through remote control or automated systems, improving the control efficiency and accuracy of the system and meeting the needs of different operating conditions.

pressure control：The overflow valve and other devices can regulate and stabilize the pressure of the hydraulic system, ensuring that the hydraulic control slow closing check butterfly valve can operate safely and reliably under different working pressures. Appropriate pressure can effectively control the closing speed and force of the valve, avoiding the impact of excessive or insufficient pressure on the normal function of the valve.

flow control：The throttle valve and other components can regulate the flow rate of hydraulic oil, thereby controlling the operating speed of the hydraulic controlled slow closing check butterfly valve. For example, in the process of requiring slow closure, adjusting the flow rate can achieve slow valve closure, reducing the impact of water hammer and other phenomena on pipelines and equipment.
