Product overview

The gas turbine fuel gas pressure regulating system is a skid-mounted system for gas turbine gas supply, which integrates the functions of filtration, heating, pressure regulating, metering, venting, releasing, leakage alarm, automatic switching and so on.

The gas turbine fuel gas pressure regulation system is generally composed of several subsystems, such as filtration heating system, metering system, pressure regulation system, vent system, gas leakage alarm system, etc. The metering system is equipped with a flow computer to calculate the gas flow through temperature and pressure compensation. The pressure regulating system has the configuration characteristics of "pressure control system", and adopts the configuration mode of "safety emergency cut-off valve + monitoring regulator + working regulator". In principle, the blow-off system adopts centralized blow-off; The gas leakage alarm system can be interlinked with the main valve and the blow-off system. When the leak danger occurs on site, the station control system will direct the main valve to close and open the blow-off system for emergency blow-off.

This system has very high requirements for the pressure regulator, first of all, it requires rapid opening and closing, fast reaction speed, high pressure regulation accuracy, and should also have a large flow capacity, with this characteristic of the pressure regulator in the axial flow regulator valve application is more common. Continuous and stable gas supply, large gas pressure adjustment range, high explosion-proof requirements, good safety performance and so on.

Product characteristics
