2.The product description and connection size

This valve electrical control system according to the main logic element class is divided into regular and PLC intelligent control, the factory necessary for normal commonly, need to type PLC intelligent control to when ordering. Each type and the following several main conditions:

Open valve working condition of centrifugal pump, including centrifugal mixed flow pump, start the pump and delay after the scheduled time open valve, or valve opened at the same time.

Centrifugal pump shut valve: the valve closed to a certain point of view, and then stop the pump. Or the pump valve with clearance.

Open valve working condition of axial flow pump, including axial mixed flow pump, pump valve at the same time open, or open the valve to a certain point of view, first to start the pump again.

Axial flow pump shut valve: valve closed

Open valve turbine operating mode: first open the bypass valve balance pressure, then open valve.

Close the valve working condition of hydraulic turbine, the main valve closed at the same time open the bypass valve, to the main valve closed bypass valve when fitted.

This valve are equipped with local control circuits of the electric control system and remote control circuits. Local control loop is mainly used in commissioning, normal work is using a remote control circuits.

Pump power for AC380V, uninterrupted power supply for control DC220V AC220V, DC110V etc, or other power supply level

3.Energy type hydraulic control slow closing butterfly valve

Accumulator type hydraulic control butterfly valve is stored in the energy accumulator for auxiliary power supply, to drive the opening and closing of the valve. Allows the valve in time no electricity situation, the energy stored inside accumulator can ensure that the valve opening and closing again. The accumulator type hydraulic control butterfly valve gear and rack type and rocker arm type two kinds of structure

Mainly by the valve body, valve actuator, hydraulic station, electric cabinet and so on four parts.

Valve body by the valve body, disc, valve stem, sliding bearing, seal assembly and other major parts.

Accumulator hydraulic control slow close check butterfly valve is generally adopts horizontal layout; Also can according to user requirements with vertical layout.

Drive gear diameter DN 1400 or more using lateral plate, rocker arm, such as connection, transmission parts, diameter DN < 1400 adopt gear rack transmission mechanism.

The driving hydraulic cylinder is slowly-closing time regulator. The user can be adjusted according to the design to go to.

Hydraulic station including unit pump, manual pump, accumulator, electromagnetic valve, relief valve, flow control valve, cut-off valve, hydraulic integrated block, fuel tanks and other components.

Accumulator system, the accumulator to provide the valve opening and closing the main power source.

Flow control valve is used as the on-off valve time adjustment, the user can speed regulation valve switch is carried out according to the design requirement.

Manual pump used for system debugging and special circumstances of the valve opening and closing.

Hydraulic system electromagnetic directional valve features as follows: solenoid valve must work electric butterfly valve, loss of electric butterfly valve, a lock; Take some of the other role type should be when ordering.

Hydraulic system and the valve body for fission installation commonly, also can be installed in a whole. User if there are no special instructions for split type of installation. Accumulator hydraulic control slow close check butterfly valve using vertical arrangement are split type installation.
