The working principle or usage mode of by-pass valve actuator described in the utility model are as follows: as shown in Fig. 1-Fig. 7, turbine
The working principle of booster is pressurizeed again to cylinder using the power of gas is discharged in cylinder, realizes power recovery.Specifically
, when cylinder is started to work, by-passing valve is in close state, and the fuel gas being discharged in cylinder at this time drives the turbine middle period
Wheel rotation, and the rotation of impeller drives the wheel rotation in coaxial compressor in turbine, impeller turns in compressor
It is dynamic and to be pipelined in cylinder so that compressor absorbs outside air, it pressurizes to cylinder, is fuel
It burns more abundant.The air inlet pipe 12 of the by-pass valve actuator is connected with compressor, and the bar assembly 3 that links is by adjusting set 9
It is connected on the by-passing valve for being set to turbine, when inner pressure of air cylinder is excessive, turbine internal lobe wheel speed is improved, and drives compression
Machine inner impeller high speed rotation, and the high speed rotation of compressor impeller increase compressor internal pressure, due to by-pass valve actuator
Air inlet pipe 12 and compressor inside be connected to, when compressor internal pressure increase to a certain extent when, cause in cover assembly 1
Pressure chamber air pressure is synchronous to be increased, and is pushed the downward radial displacement of diaphragm 2, is pushed and its downward diameter of close-connected linkage rod end cap 31
To displacement, drive the adjusting sleeve 9 for being located at linkage 32 bottom end of club shaft mobile, the 9 bottom end fixed ring 91 of adjusting sleeve and by-passing valve
Valve is connected, therefore drives by-passing valve valve mobile, opens by-passing valve.After by-passing valve is opened, turbine interior and outside
Therefore the wheel speed of atmosphere, pressure reduction, turbine interior declines, drive the decline of compressor internal lobe wheel speed, make to press
Contracting machine air demand into cylinder is reduced, and is adjusted internal cylinder pressure with this, is prevented cylinder load excessive, realizes decompression protection function
Energy.When inner pressure of air cylinder reduces, turbine internal lobe wheel speed is reduced, and compressor wheel rotational speed reduces, and makes pressure inside compressor
Power reduces, due to being connected to inside the air inlet pipe 12 and compressor of by-pass valve actuator, when compressor internal pressure increases to centainly
When degree, the pressure chamber air pressure in cover assembly 1 is caused to reduce, keeps the driving linkage rod end cap 31 of spring 4 mobile to pressure chamber, into
And drive the adjusting sleeve 9 for being located at linkage 32 bottom end of club shaft mobile, close by-passing valve.After by-passing valve is closed, in turbine
Portion and external atmosphere, pressure improve, therefore the wheel speed of turbine interior rises, and drive on compressor internal lobe wheel speed
It rises, increases compressor air demand into cylinder, internal cylinder pressure is adjusted with this, realizes the pressure process to cylinder.
It should be pointed out that for those of ordinary skill in the art, without departing from the principle of this utility model,
Several improvements and modifications can be made to this utility model, these improvement and modification also fall into the utility model claims
In protection scope.
