Regulating Valve Turbine High Pressure Regulating Valve
Introduction
Pressure-regulating valve is safety equipment of the hydropower
station with long pressure diversion penstock. For a power station
with a long pressure diversion system, it is impossible to select a
suitable guide vane shutdown time so that the pressure rise ζ of
the pressure diversion system and the rate rise β of the unit are
within the allowable range. In order to ensure the stability of the
unit transition process, the method of setting up surge tank
(tower) is often adopted.
Application
The product consists of a low-flow resistance single-seat (sleeve)
valve body, a bellows (sleeve) balance piece and an actuator. It is
a new-generation valve product that complies with international
standards.
Its characteristics are:
1. An energy-saving automatic control system without additional
driving energy, low equipment costs and suitable for explosive
environments;
2. Simple structure and small maintenance workload;
3. Set points Adjustable and wide range, convenient for users to
continuously adjust within the set range;
4. Diaphragm-type actuators have higher detection accuracy and
sensitive action than cylinder-type mechanisms;
5. Pressure balance mechanism is used in the valve to make the
regulating valve respond sensitive and control Accurate and allow
large differential pressure. The product requires no external
energy, simple product structure, convenient use, and low
maintenance workload. It is especially suitable for urban heating,
heating, and no external power supply, gas supply and the need to
control liquid and gas pressure. According to foreign reports, the
use of this product in urban heating and heating systems can
improve energy efficiency by 30% -40% compared to previous times,
with significant effects.
