product overview

The gas turbine fuel gas pressure regulating system is a skid mounted system that supplies gas to the gas turbine, integrating functions such as filtration, heating, pressure regulation, metering, venting, release, leakage alarm, and automatic switching.

The fuel gas pressure regulating system of a gas turbine generally consists of several subsystems, including a filtration heating system, a metering system, a pressure regulating system, a venting system, and a gas leakage alarm system. The metering system is equipped with a flow computer, which calculates the standard gas flow rate through temperature and pressure compensation; The pressure regulating system has the configuration characteristics of a "pressure control system" and adopts the configuration method of "safety emergency cut-off valve+monitoring regulator+working regulator"; In principle, the venting system adopts centralized venting; The gas leakage alarm system can be interlocked with the main valve and venting system. When a leakage danger occurs on site, the station control system commands the main valve to close and opens the venting system for emergency venting.

This system has high requirements for pressure regulating valves. Firstly, it requires rapid opening and closing, fast response speed, high pressure regulation accuracy, and a large flow capacity. Axial flow pressure regulating valves are widely used among pressure regulating valves with this characteristic. Continuous and stable gas supply, wide range of gas pressure regulation, high explosion-proof requirements, and good safety performance.
