Description
Technical field
The present invention relates to a kind of gas regulation mechanism, especially a kind of miniature gas turbine combustion gas controlling mechanism.
Background technique
One of important development direction of efficient, the clean energy technology of to take miniature gas turbine as the distributing-supplying-energy system of core be 21st century, as the leading edge developments direction of advanced energy technology, has been put in China, long time scientific and technical development outline.Miniature gas turbine is also the military equipment that national defense construction is badly in need of.Development micro-gas-turbine machine technology is extremely important for Chinese national economy sustainable development and reinforcement national defense construction, has broad application prospects.
Combustion gas controlling mechanism is mainly by carrying out shunt regulating to the high-temperature fuel gas of discharge of gas turbine, change the ratio realization output to different energy sources of combustion gas by each system, because China does not also have ripe miniature gas turbine cogeneration product at present, so also belong to blank for the application of regulation structure.
Summary of the invention
The object of this invention is to provide a kind of miniature gas turbine combustion gas controlling mechanism, the energy supply form of miniature gas turbine can be regulated, meet the demand of user to the variety classes energy.
Technical solution of the present invention is as follows:
Micro fuel engine combustion gas regulation structure comprises regulation structure housing, butterfly valve, driving mechanism, stepper motor, stop switch, transmission shaft, described controlling mechanism housing is the flow pipe of high-temperature fuel gas, its import exports with gas turbine and is connected, outlet is connected with needing each system of combustion gas, butterfly valve is arranged in the pipeline of the export pipeline of regulation structure housing, described inner-walls of duct is also provided with the positive stop lug boss preventing butterfly valve overtravel, described rotating mechanism comprises stop switch button, driving link, driven member and drive link, driving link one end is fixedly connected with the output shaft of stepper motor, the other end successively with drive link, driven member strand connects, driven member is fixedly connected with the transmission shaft in the pipeline putting in export pipeline, described transmission shaft is fixed butterfly valve and butterfly valve can be driven to rotate, described driven member is provided with two stop switch buttons, controlling mechanism housing is provided with stop switch, when butterfly valve is opened to maximum value and closes completely, two stop switch buttons can start stop switch respectively, described stop switch is connected with the power supply line of stepper motor, the outlet of described regulation structure housing is multiple.Described controlling mechanism housing is installed the position of transmission shaft, between the side and transmission shaft of driving mechanism, be filled with stuffing box packing, outside pressing plate is fixed, and opposite side is provided with sealing cover.Described positive stop lug boss is two semi-circulars.Described transmission shaft, through the center of butterfly valve, connects butterfly valve by woodruff key and is connected, butterfly valve is synchronously rotated centered by transmission shaft.
The present invention is by arranging the mechanism of butterfly valve and the motion of control butterfly valve, can according to user to variety classes energy demand, controlling mechanism is driven by stepper motor, by rotatingshaft, butterfly valve is rotated, by changing the circulation area of fuel gas exhaust passage, high-temperature fuel gas is flow in required equipment by demand, is converted to the energy required for user.The positive stop lug boss arranged and stop switch can limit butterfly valve overtravel and stepper motor transships and burns; Stuffing box packing, stuffing box packing pressing plate and sealing cover form combustion gas seal structure jointly, prevent high-temperature fuel gas from revealing.Positive stop lug boss can be arranged to two semi-circulars, when butterfly valve is closed completely, can play seal action further.Present invention employs adjustable gas emission structure, different energy sources can be provided flexibly according to the demand of user, by stepper motor, also accurately can control the discharge ratio of combustion gas while can Electronic control being realized, accomplish the accurate control of the required energy.
