الوصف
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 .

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.
