The utility model is mainly characterized in that the work oil circuit is provided with an oil tank, an oil suction sieve, a ball valve, an oil pump motor, an oil pipe, a ball valve, a pressure piping filter, a one-way valve, an overflow valve, an accumulator, a pressure relay, an electro-hydraulic servo valve, a one-way throttle valve and an oil cylinder lever. The displacement sensor, an air valve stem and the oil cylinder lever are linked to ensure that an output frequency signal is corresponding to a displacement signal in a one-to-one mode. The gas regulating device for a combustion turbine has the advantages of simple structure, high accuracy of regulation, wide range, high response speed, convenient assembly and low cost.
Description
Technical field
The utility model relates to a kind of air regulating device, particularly relates to the adjusting device of gas turbine combustion gas.
Background technology
At present, the gas turbine overwhelming majority is to be fuel with natural gas or fuel gas, but under different operating modes, required fuel consumption has nothing in common with each other.Be head it off, occurred many gas regulating devices on the market, have plenty of that to take with the electricity be the adjusting device of drive energy, or take to be the adjusting device of drive energy altogether, the air regulating device of many other forms is also arranged with gas and electricity.Though these air regulating devices can play the effect of adjustments of gas fuel flow rate, degree of regulation is low, response speed is slow, adjustable range is narrow, volume is big, cost is higher, easy-maintaining not.
Summary of the invention
The utility model is in order to overcome the shortcoming that prior art exists, and proposed a kind of simple structure, degree of regulation height, scope is wide, response speed is fast, be convenient to assemble and gas turbine gas regulating device that cost is low.
The utility model adopts following measure to realize above-mentioned purpose.
Include displacement transducer, air valve stem and working oil path, main feature is: be connected with fuel tank, oil suction filter, ball valve, Oil pump electrical machinery, oil pipe, pressure piping filter, check valve, overflow valve, accumulator, pressure switch, electrohydraulic servo valve, one-way throttle valve and oil cylinder lever on working oil path in turn.The flow direction of electrohydraulic servo valve control working oil path oil is given the different oil pressure of oil cylinder piston both sides oil pocket, and driven plunger moves and drives moving of air valve stem, thus the size of regulating air valve opening.
Set accumulator on working oil path is in order to keep the constant of oil pressure in the working oil path.Two set one-way throttle valves are used for the speed of coarse adjustment oil cylinder lever forward and back motion.Displacement transducer and air valve stem and the series connection of oil cylinder lever also realize interlock, guarantee that the frequency signal of output is corresponding one by one with displacement signal.
The utility model is simple in structure, degree of regulation is high, scope is wide, response speed is fast, be convenient to assembling, cost is low.

The specific embodiment
On oil circuit, be connected with fuel tank 1, oil suction filter 2, ball valve 5, Oil pump electrical machinery 3, oil pipe 4, ball valve 5, pressure piping filter 6, ball valve 5, check valve 7, overflow valve 8, pressure switch 10, accumulator 9, electrohydraulic servo valve 11, check valve 7, one-way throttle valve 12, oil cylinder lever 13 in turn.By the flow direction of electrohydraulic servo valve 11 control oil circuit oil, give the different oil pressure of oil cylinder piston both sides oil pocket, driven plunger moves and drives moving of air valve stem 14, thus the size of regulating air valve opening.By control, regulate the motion state and the position of oil cylinder lever to electrohydraulic servo valve 11.
Regulate overflow valve 8 and regulate the height of oil circuit pressure, discern the size of pressure in the oil circuit by pressure switch 10 exactly.
Displacement transducer device 15 is with air valve stem 14 and 13 series connections of oil cylinder lever and realize interlock, makes the frequency signal of output corresponding one by one with displacement signal, thus the size that response speed can accurately be regulated air valve opening soon.Before the driving, the ball valve before the Oil pump electrical machinery 3 is in the open position, and 6 need of two-way pressure piping filter open one the tunnel.
Connect Oil pump electrical machinery 3 power supplys, clockwise rotate overflow valve 8 handles, regulate oil pressure to operating pressure, operating pressure can be adjusted in 3.5MPa～5MPa scope according to the size of load.
Two one-way throttle valves 12 are used for the speed of coarse adjustment oil cylinder lever 13 forward and back motion in the oil circuit, are adjusted to soon clockwise, are adjusted to slow counterclockwise.
After parking, overflow valve 8 is rotated counterclockwise the oil pressure of backing off earlier.
