La description

Our company produces the hydraulic control butterfly valve, it is a kind of high intelligence, high efficiency, high energy saving hydraulic controlled check disc valve products, divided into the accumulator type hydraulic controlled check butterfly valve and heavy hammer type hydraulic controlled check butterfly valve.
This series product is relatively advanced automatic pipeline control equipment at home and abroad, mainly installed in hydropower turbine inlet, used as a turbine inlet valve, or installed in a water plant, power plants, steel plants, paper making, chemical industry, municipal construction system, such as the water pump of water supply and drainage pumping station exit, replace the function of the check valve and gate valve, cut-off, recycling.
Hydraulic control check disc butterfly valve on the working, by default the opening and closing procedures, can switch line, and can effectively eliminate water hammer under the action of a hydraulic slowly-closing, realize reliable cutoff of pipeline, prevent damage to piping system.

storage tank-hydraulic control butterfly valve
the characteristic
1. can hold the device and can hold by two , can turn off the valve automatically when there is no outside energy
2. it is reliable and flowing to hinder coefficient small to seal
3. Adopt PLC intelligent control system , can realize such many kinds of humanization as the text , touch- sensitive screen etc. operate interfaces
4. can realize long-range local control
5. can realize long-range , local control
6. have fast , slow adjustable closing the function
7. close it , stop going back the function
8. can realize while closing that close the function slowly, dispel water hammer to endanger effectively , protect the security of the water pump and pipe network system .

Note: can use other relevant standards and foreign standards, the flange size can be made according to user requirements, but should be in the order stated in the contract
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 AC**0V, uninterrupted power supply for control DC**0V AC**0V, DC**0V 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 ***0 or more using lateral plate, rocker arm, such as connection, transmission parts, diameter DN < ***0 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.
