Product features:

Hydraulic turbine inlet valve - hydraulic ball valve is widely used in hydropower stations with high water head. When working, the valve and turbine cooperate according to the hydraulic transition

According to the principle, through the preset opening and closing procedure, the water hammer of pipeline can be effectively eliminated to realize reliable cut-off of pipeline and play the role of protecting the safety of pipeline system.

It is installed at the water inlet of turbine volute to provide reliable and safe working conditions when the unit stops for maintenance. Long downtime on unit

When reducing water leakage of the unit, quickly filling water when starting up, so that the unit quickly into the working state; It can also prevent the aircrew from escaping.

Our company also can be designed separately according to the special requirements of users, to meet the needs of users for this kind of products.

In addition to conventional ball valves, our company also develops and produces liquid control ball valves with maintenance seals. The sealing device is designed for bilateral sealing, one side

For work seal, one side for maintenance seal. There is no need to install a special maintenance valve before the water inlet ball valve, and the maintenance seal is put in

In this way, the working seal and shaft end seal can be repaired without emptying the pressure pipe, which saves the operation and maintenance cost of the power station.

2. Structure description

Liquid control ball valve mainly consists of ball valve body, hydraulic station, PLC electric control box (cabinet), bypass pipeline and bypass valve, upstream connection pipe, downstream connection

Pipe, expansion joint, air valve, drainage valve and other main parts, the design conforms to GB/ t14478-93 large and medium-sized turbine inlet valve basic

Technical conditions.

3. Performance characteristics

This series of valves have high intellectualization degree, complete functions, stable and reliable performance, and the flow resistance coefficient is very small, the flow resistance coefficient when fully open is equal to the pipeline.

The products have the following main features:

1. The electrical control system adopts PLC intelligent control, which greatly simplifies the electrical circuit and has strong fault self-diagnosis function. Local, remote

Control, subject to central control room and linkage control with turbine, high degree of automation, safe and reliable, is to achieve the hydropower station "few people on duty, no duty"

Ideal equipment for management concept;

2. The hydraulic control system USES an accumulator to store energy. When the hydropower station is out of power, the accumulator releases energy, which can realize emergency water shutoff ball valve and install the unit

Full operation to provide adequate safety assurance;

3. applicable to a wide range of head, up to 1600 meters head;

4. fluid resistance is small, ball valve is the least fluid resistance of all valves, valve fully open, the flow channel for smooth through hole, hydraulic loss is small.

5. quick and convenient switch, as long as the stem rotation of 90°, the ball valve to complete the full open or closed action, it is easy to achieve rapid opening and closing.

6. Valve stem sealing is reliable. Ball valve open and close the stem only rotation movement, so the stem packing seal is not easy to be broken, and stem inverted seal of the dense
