Water Turbine Inlet Hydraulic Butterfly Valve

The whole equipment of this Water Turbine Inlet Hydraulic Butterfly Valve includes upstream extension pipe, water inlet hydraulic butterfly valve, water inlet valve expander, downstream extension pipe, bypass pipe, bypass pipe control valve, bypass pipe maintenance valve, air valve, etc. Ideal equipment for cutting off or connecting media in pipeline systems in hydropower stations.

Function of the water turbine inlet hydraulic ball valve

1. When the hydraulic turbine unit in an accident, the emergency water will close the water inlet hydraulic butterfly valve to protect the safety of the unit;

2. In a multi-machine hydropower station with one pipe, when a unit fails to be repaired, the maintenance work can be carried out by closing the water inlet hydraulic butterfly valve in front of the unit without affecting the normal operation of other units;

3. When the unit is shut down for a long time, close the water inlet hydraulic butterfly valve, which can reduce the peristalsis of the unit and reduce the start-up time.

Features

1. The valve body and valve are formed by casting and welding. The outside of the valve body adopts a T-shaped reinforced structure, and the Water Turbine Inlet Hydraulic Butterfly Valve adopts a double-plate frame structure or a streamlined structure, which has high strength and good rigidity. The water inlet and outlet parts are designed with flow diversion or streamline, and the hydraulic characteristics are good. The flow resistance coefficient of the water inlet hydraulic butterfly valve is less than 0.2;

2. The rubber soft seal adopts a double eccentric structure, and the metal hard seal adopts an all-metal elastic metal seal structure, making full use of the hydraulic self-closing characteristics of the hydraulic butterfly valve to ensure the reliability of valve closing under any working condition;

3. The fluid energy of the accumulator or the potential energy of the heavy hammer drives the servomotor of the hydraulic butterfly valve to open or close the hydraulic butterfly valve; the pressure maintaining performance of the hydraulic system is good, and the valve is opened or closed according to the preset program The whole process of the valve is controllable (the hydraulic system can be designed with various pressure levels for users to choose).

Product Specification

Application

The hydraulic control valve is the most widely used water turbine inlet valve, suitable for installation in the penstock in front of the turbine. Application industry: water conservancy, electric power, etc.
