Turbine set inlet hydraulic butterfly valve is generally used at the entrance of hydropower station or pumped storage power station turbine set with water head higher than 250M. the whole valve set includes upstream and downstream connecting pipe, valve body, expansion joints, bypass valve, exhaust valve, etc., Design in line with GB / T14478-1993 "large medium-sized turbine inlet valve basic technical conditions" requirement. Its role is:
1, When a main water supply pipe supplies water to several turbine sets, one of them need to be inspected and repaired, to cut off the flow without affecting the operation of other units.
2, When meeting with turbine set speed system accident, the turbine set speed increases to set value, the valve will be emergency shut down to prevent the accident from expanding.
3, When the turbine set stopped working for a long time, to cut off the upstream water, in order to reduce the guide vane leakage, to prevent the unit peristalsis.
4, Valve is equipped with a working seal and inspection/ repairing seal, When inspection and repairing seal works, we could inspect and repair working seal and shaft end seal, without venting the water in pressure pipe before valve. When inspection and repairing seal works, the valve is equipped with hydraulic locking and manual locking, to ensure absolute safety during maintenance. The valve does not need to install a special repair valve, can save the project investment costs.
5, The hydraulic system uses energy storage tank technology, In the case of emergency power failure, the valve will be closed, to ensure the safety of whole turbine set system.
6, Uses self-regulating shaft seal; uses lead-free self-lubricating bearings. The seal box and shaft end supports are designed as components that are mounted outside the valve flow path, easy to disassemble and repair.
7, PLC programmable logic controller can be used as the electrical control part, to greatly simplify the electrical circuit and according to different working condition requirements, only need to change the program, do not need to change the line, with high versatility. At the same time, the use of PLC makes the valve has self-diagnostic function, and easy to connect to central control room computer.
8, Valve has automatic clean function to the weeds, mud, dirt and other dirt attached in the valve sealing surface. Sealing surface service life is long.
