This product is a new hydraulic turbine inlet weight hydraulic control butterfly valve, known as the hydraulic turbine water inlet weight hydraulic butterfly valve or hydropower valve open lock automatic pressure hammer control hydraulic check butterfly valve, ordinary type, mud prevention Sand type two, anti-sediment type hydraulic butterfly valve is used for hydropower projects with sediment and other impurities in water, and seawater-proof hydraulic control butterfly valve is used for pump stations where the medium is sea water or river water mixed with seawater and other working conditions.
The hydraulic butterfly valve is hydraulically driven to open and the hydraulic pressure can reach 15MPa, reducing the volume of the servomotor. During the opening process, the hammer is lifted, the lifted hammer is used for energy storage, the storage tank is cancelled, and the lock is opened. Automatically put in, the hydraulic system automatically maintains the pressure, the weight does not fall, the disc does not shake. When power is off, no power source is required, and the locking pin is automatically released and shut down according to a predetermined procedure. This is simple and reliable, greatly simplifying the hydraulic system. With three eccentric valve plates, the horizontally installed valve shaft raises a certain distance on the centerline of the pipe, so that the lower half of the valve plate meets the water area larger than the upper half, and can use the action of the hydraulic force to help the valve close to reduce the weight of the weight. Weight, the structure of a simple, small size of the hydraulic device, butterfly valve control cabinet, electrical automatic control box, servomotor, control tubing is very compact with the valve together, without the user's additional configuration. The valve can realize on-site control, remote control and linkage control, which can meet the requirements of "no one on duty, less people on duty", and is an ideal new type of pipeline control equipment.
This type of hydraulic butterfly valve is the ideal equipment for cutting off or connecting the medium in the pipeline system of hydropower. It is suitable for being installed at the pressure pipe before the turbine. As the inlet valve of the turbine, its role is:
1. When the turbine accident occurs and the guide van cannot be closed, the moving water closes the valve and shuts off the flow of water in an emergency to prevent the turbine from flying and ensure the safety of the unit.
2. When the unit is at stand-by, close the valve and cut off the water flow to prevent the water guide vanes from leaking for a long time. This will not only reduce the loss of water energy, but also prevent gap cavitation at the end face and facade of the guide vane.
3. When the unit is shut down for maintenance, the static water closes the valve and cuts off the flow of water.
The butterfly valve is also suitable for high position in the beginning of the pressure pipe, used as a pressure pipe protection valve, in the case of bursting of the pressure pipe, etc., emergency shut-off shut-off water to prevent the accident from expanding to ensure safety.
The drive device of this series of butterfly valves can be designed on the left or right side of the flow direction according to the needs of the workshop, and the heavy hammer can be designed to be inverted along the flow direction or against the flow direction according to the needs of the power station.
