700mm~4000mm Butterfly Valve Diameter Hydro Turbine Generators
The role of butterfly valve in hydropower station
The main functions of closing the water inlet of the water-guiding
mechanism of the hydro-turbine generator set are as follows: 1.
Close the water inlet, and no water can pass through the guiding
blades, and the dao hydro-turbine generator set can enter the
maintenance state and the static water test state, such as
simulated boot , Shutdown,'load rejection test, etc. 2. If an
abnormality occurs during the normal operation of the unit, if the
speed control system cannot be shut down normally, the butterfly
valve device can be urgently closed to achieve the purpose of
stopping the unit.
Hydro Turbine Generators Applicable Range
Head: 20-200m Flow: 0.15-10m3/s
Most widely used turbine in the world. (70-80%)Applicable head and
flow range is very wide.As a type of reaction turbine, the draft
tube can be used to effectively increase net head.Peak efficiency
is highest among all turbine types. (85-94%)Due to its complex
design and large number of moving parts, maintenance and repair can
be significant.
