Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, and it is not used in restriction the utility model.
As shown in figure 1, a kind of automatically controlled adjusting means of gaseous-pressure, including：Needle-valve 1, controller and pressure sensor 3.
Needle-valve 1 includes the drive device that hollow valve body, the valve rod 13 in valve body and driving stem 13 are moved.
Valve body is collectively forming by the bottom end cover 11 and upper end cover 12 being fixed together, and bottom end cover 11 is provided with air inlet
111 and gas outlet 112, and the air flue 113 being connected between air inlet 111 and gas outlet 112, upper end cover 12 be provided with bearing
Mounting hole 121, bearing mounting hole 121 is interior to be provided with the cover plate 18 being fixedly connected with upper end cover 12, and cover plate 18 moves provided with valve rod
Hole 181.
Drive device includes motor 14, and motor 14 is fixed on upper end cover 12, and the output end of motor 14 is fixedly connected with master
Moving gear 15, driving gear 15 are engaged with driven gear 16, and the center of driven gear 16 is provided with tapped through hole, the He of driving gear 15
Driven gear 16 is respectively positioned between bottom end cover 11 and upper end cover 12, is provided with and is used between the upper end of driven gear 16 and upper end cover 12
The bearing 17 that driven gear 16 is axially moved is limited, bearing 17 is located in bearing mounting hole 121, and the lower end of driven gear 16 is with
A bearing 17 for being used to limit the axial movement of driven gear 16, two bearings 17 and driven gear 16 also are provided between end cap 11
Between be respectively equipped with an annular stop plate 19, annular stop plate 19 is sheathed on valve rod 13, and sealing is also arranged with valve rod 13
Circle 10, sealing ring 10 is between bearing 17 and bottom end cover 11.
One end of valve rod 13 is the pintle end 131 in aciculiform, and pintle end 131 is stretched into air flue 113, the other end of valve rod 13
To set the threaded end of thread 132, the end of thread 132 is threadedly connected in tapped through hole, and the end of thread 132 runs through tapped through hole, and
It can be moved up and down in valve rod moving hole 181.
Pressure sensor 3 is stretched into air flue 113, and pressure sensor 3 is fixed on bottom end cover 11, positioned at close to gas outlet
At 112, pressure sensor 3, motor 14 are electrically connected with the controller respectively, and controller is preferably Engine ECU 2, can also be selected
