Further, the outside of described spool is provided with one week core sealing groove, in described core sealing groove, be embedded with seal ring, seals and contact between described seal ring and the cavity madial wall of valve body.
Further, the outside of described spool is provided with one week spool force-bearing table, and the rear end of described Returnning spring contacts with described spool force-bearing table installs.
Further, the helicoid peak of described spool is provided with guide and limit post laterally, guide and limit groove is axially arranged with at the corresponding position of described valve body madial wall, described guide and limit post is embedded in described guide and limit groove, make described spool be limited to move vertically, and make described power-converting part be directed to limited post restriction limit position when the rollback spinning movement doing spool.
Further, the center of described spool is provided with groove, the center of described power-converting part is provided with the nose bar embedded in this groove, positive stop lug boss is pushed away before the helicoid peak of spool is provided with to the inside, the helicoid peak next-door neighbour nose bar position of power-converting part is provided with conversion part limiting stopper, is front pushed away positive stop lug boss and limit limit position when making described power-converting part push away spinning movement before doing spool.
The beneficial effects of the utility model are that overall structure assembling is simple, and flow gas can aperture regulating and controlling, and hydrodynamic pressure is stablized, it is little to fluctuate.The utility model is the mode moved up and down by the controlled conversion of motion by a circumference of spool, carry out the size of the relative distance of regulating spool sealed bottom face and valve body sealing surface, thus control the size of gas flow, this spool is connected with stepper motor by spool link, the size of relative distance is accurately controlled by stepper motor, obviously such control more precisely flexibly, can not be subject to the interference of the external factors such as uninterrupted, so the utility model is more accurate to the control of flow.In the utility model, the circular movement of an individual pen of the helicoid of spool and power-converting part is relied on to be converted to controlled axial motion, utilize the elastic force of Returnning spring to carry out its motion auxiliary simultaneously, unlatching and the sealing aperture of fluid passage control fast effectively, and silica gel sealing ring spool is equipped with and valve hole matches to seal, serve good sealing effect.

Fig. 2 is the cross sectional view that the utility model crosses axis,
Fig. 3 is spool and spool connecting body schematic enlarged-scale view.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated: as Fig. 1, shown in 2, described electrical adjustment fluid flow valve, comprise stepper motor 6, power-converting part 5, Returnning spring 2, spool 4 and the valve body 1 being provided with cavity, the front end of described valve body 1 and side are respectively equipped with air inlet nozzle 8 and outlet nozzle 9, described spool 4 mobile air inlet nozzle 8 that makes in the cavity of valve body 1 is opened to the fluid passage of outlet nozzle 9 or is closed, described power-converting part 5, spool 4 and Returnning spring 2 are installed in the cavity of valve body 1 to extreme direction before valve body successively, the output shaft of described stepper motor 6 is connected with the rear end of described power-converting part 5, the surface of contact that described power-converting part 5 axially contacts with spool 4 is helicoid, described Returnning spring 2 is installed between the cavity ground of described spool 4 and described valve body 1 front end.The outside of described spool 4 is provided with one week core sealing groove 16, in described core sealing groove 16, be embedded with seal ring 3, seals and contact between described seal ring 3 and the cavity madial wall of valve body 1.The outside of described spool 4 is provided with one week spool force-bearing table 17, and the rear end of described Returnning spring 2 contacts with described spool force-bearing table 17 installs.
As the constructive embodiment in Fig. 1, helicoid rotates a circle, and is formed in the start line of helicoid and terminated line place with individual vertical section.
As Fig. 3, in order to ensure the accurate and reliable of control, the helicoid peak of described spool 4 is provided with guide and limit post 12 laterally, guide and limit groove 18 is axially arranged with at the corresponding position of described valve body 1 madial wall, described guide and limit post 12 is embedded in described guide and limit groove 18, make described spool be limited to move vertically, and make described power-converting part 5 be directed to limited post 12 when the rollback spinning movement doing spool to limit limit position.
The center of described spool 4 is provided with groove, the center of described power-converting part 5 is provided with the nose bar embedding this groove, before the helicoid peak of spool is provided with to the inside, pushes away positive stop lug boss 19, is front pushed away positive stop lug boss when power-converting part 5 pushes away spinning movement before doing spool and limit limit position.
As Fig. 1,3, when stepper motor 6 drives power-converting part 5 to turn clockwise, the vertical section of power-converting part 5 finally can meet with the vertical section of spool.Because guide and limit post 12 is limited in the guide and limit groove 18 of spool by nested, the rotation of power-converting part 5 is stopped.As Fig. 3, when stepper motor 6 drives power-converting part 5 to be rotated counterclockwise, conversion part limiting stopper 15 pushes away positive stop lug boss 19 before finally running into spool, because guide and limit post 12 is limited in the guide and limit groove 18 of spool by nested, the rotation of power-converting part 5 is stopped.
When stepper motor 6 drives power-converting part 5 to be rotated counterclockwise, conversion part limiting stopper 15 pushes away positive stop lug boss 19 before finally running into spool, because guide and limit post 12 is limited in the guide and limit groove 18 of spool by nested, the rotation of power-converting part 5 is stopped.
When stepper motor 6 drives power-converting part 5 to turn clockwise, helicoid peak slid clockwise on the helicoid of spool of power-converting part 5, under the effect of Returnning spring, spool gradually on move, Flow valve fluid passage progressively, until limit position.When stepper motor 6 drives power-converting part 5 to be rotated counterclockwise, the helicoid peak of power-converting part 5 slides counterclockwise on the helicoid of spool, compression reseting spring, and spool moves down gradually, and Flow valve fluid passage is progressively closed, until limit position.In the mobile whole process of spool, power-converting part 5 mobile a week at most, opening and closing procedure block, efficiency is high, and valve is easy to adjust to standard-sized sheet aperture from complete shut-down, and precision is high, is convenient to control.Because seal ring contacts with valve seal, airtight performance is good.Returnning spring uses less elastic force can realize moving axially control, and the loss of stepper motor is little, and efficiency is high.
