Turbine inlet pneumatic valve - Hydraulic control butterfly pneumatic valve structure characteristics, technical parameters

- turbine inlet pneumatic valve Pneumatic valve hydraulic control butterfly ( Accumulator, swinging type relay device)
- turbine inlet pneumatic valve Hydraulic control butterfly pneumatic valve product introduction:
- turbine inlet pneumatic valve Hydraulic control butterfly pneumatic valve in accordance with the requirements for hydropower development, our company is manufacturing a energy saving pneumatic valve products. Cooperate with turbine work, pneumatic valve, according to the principle of the transient process of water through the preset opening and closing procedures, effectively achieve reliable line by elimination, play a role to protect the safety of pipeline system. Installed in the inlet of spiral case, to provide reliable safety when the machine stop working conditions; During long time stop is to reduce the unit water leakage, rapid filling water when the phone is switched on, quickly enter the working state of generating unit; Can also prevent a runaway.
- turbine inlet pneumatic valve Pneumatic valve series pneumatic hydraulic control butterfly valve by pneumatic valve hydraulic control butterfly ( The pneumatic valve) , transmission device, relay device, hydraulic station, intelligent electric cabinet ( Ark) , bypass piping system, connecting pipe, the downstream connecting pipe, expansion joints, pneumatic air valve, pneumatic valve of main parts, such as drainage design in accordance with GB/T - The basic technical conditions of large and medium-sized water turbine inlet pneumatic valve.
- turbine inlet pneumatic valve Hydraulic control butterfly pneumatic valve structure has the following characteristics:
and electric control system adopts PLC intelligent control, make electrical wiring greatly simplified, with strong fault self-diagnosis function. Can be local, remote control, is controlled by the computer and the turbine linkage control, high degree of automation, safe and reliable, and realize power station 'less people and unmanned on duty of duty' management idea;
and hydraulic control system USES a heavy hammer or accumulator energy storage, when hydropower station blackout without power supply, a heavy hammer or accumulator can release, which can realize the emergency pneumatic water closing butterfly valve, to ensure the safe operation of the unit to provide enough security;
and electrical control box with hydraulic station overall installation, also can separate arrangement, depending on the condition on site selection;
and main pneumatic valve sealing surface for triple eccentric metal seal or double eccentric rubber sealing structure, easy opening and closing, reliable sealing; And there is a additional increase of eccentricity, to close the pneumatic valve has good self, self sealing performance. Medium and small size butterfly plate designed to streamline plate structure, bore diameter disc designed double plate girder structure, crowd out small, smooth flow, pneumatic valve, flow resistance coefficient is only. ~。 , is far less than the check of the pneumatic valve flow resistance coefficient ( 。 ~。 ） , energy saving effect is obvious.
, pneumatic valve body USES casting or welding, the overall framework form, high strength, good sealing performance;
, by-pass pipe is equipped with manual maintenance, electric pneumatic valve, pneumatic valve, slip of electropneumatic valve hydraulic control pneumatic valve can be used instead of, and with the main pneumatic valve linkage control.
and downstream connecting pipe can be equipped with air pneumatic valve, pneumatic valve, sewage, depending on the requirements of customers and site. To run the program: open the pneumatic valve, open the ventilation move valve and differential pressure balance to open the main pneumatic valve, pneumatic valve shut close beside the ventilation valve: open the vent pneumatic valve to close the main valve to close beside the ventilation action valve
