In the time using, first refer to shown in Fig. 1 to Fig. 3 A, this drive unit 80 drives this driving shaft to rotate, make these ellipse valve 70 to one closed positions of these driving shaft 40 turns, now, this elastic component 723 distortion and be flexibly resisted against the internal ring wall 11 of this housing 10 slightly, whereby, this passage 111 is sealed completely, and the gas of passage 111 1 sides or liquid cannot flow to the another side of passage 111 by oval valve 70.Refer to shown in Fig. 4 and Fig. 5, this drive unit 80 drives this driving shaft 40 to rotate, make these ellipse valve 70 to one enable possitions of these driving shaft 40 turns, now, this elastic component 723 is no longer resisted against the internal ring wall 11 of this housing 10 and reverts to the Zhang Zhanzhuan under nature away from the internal ring wall 11 of this housing 10, this passage 111 is opened completely, and the gas of passage 111 1 sides or liquid can flow to the another side of passage 111 by the gap between oval valve 70 and the internal ring wall 11 of housing 10.
Flow dontroller of the present invention is available for users to control oval valve 70 by this drive unit 80 need to, by driving shaft 40 how many rotation angles of turn, reach effect of the flow of accurate control gas or liquid whereby.
Secondly, this ellipse valve 70 is in turn process, because elastic component has certain elastic deformability, the internal ring wall 11 of housing 10 can be by 723 scratches of elastic component whereby, and in the time that oval valve 70 is positioned at closed position, the elastic deformability of elastic component 723 can make the oval valve 70 can be thoroughly and internal ring wall 11 drive fits of housing 10 and seal this passage 111 completely, especially " the first width of this elastic component 723 is not more than the minor axis of this ellipse valve 70, the second width of this elastic component 723 is slightly larger than the internal diameter of the major axis of this ellipse valve 70 and the internal face 11 of this housing 10 under nature " technical characteristics situation under drive fit and sealing effect outstanding especially.
Moreover, under High Temperature High Pressure or strong acid and strong base environment, can not produce gross distortion or rotten in order to replace the material of the rubber of prior art or the elastic component 723 of plastic cement material packing ring, therefore this elastic component 723 does not have the puzzlement of known rubber, plastic washers aged deterioration, makes flow dontroller of the present invention be applicable to the environment of High Temperature High Pressure or strong acid and strong base.
Again, this determines the shape of groove corresponding to outer periphery 711 shapes of this baffle plate 71, whereby, respectively the outer periphery 711 of the internal ring wall of this conjunction 721 and this baffle plate 71 keep combining closely, especially in the time that the material of each this conjunction 721 and baffle plate is identical, respectively this conjunction 721 is all consistent with the combination effect of baffle plate 71 under any temperature and pressure condition, makes flow dontroller of the present invention be applicable to High Temperature High Pressure or strong acid and strong base environment.
In addition, this elastic component 723 is located in the shape of part of annular groove corresponding to the shape of this annular groove, whereby, respectively the external annulus of this conjunction 721 and this elastic component 723 keep combining closely, especially in the time that the material of each this conjunction 721 and elastic component 723 is identical, respectively this conjunction 721 is all consistent with the combination effect of elastic component 723 under any temperature and pressure condition, makes flow dontroller of the present invention be applicable to High Temperature High Pressure or strong acid and strong base environment.
It is worth mentioning that, because conjunction 721 is outer periphery 711 of being removably located at baffle plate 71, make the structure of each conjunction 721 can coordinate the shape of the members such as baffle plate 71, driving shaft 40 and back shaft 50 and position to do to change, whereby, sealing device 72 is applicable to the baffle plate 71 of different size or shape.
A bit be noted that in addition, this baffle plate 71 is " ellipse ", this baffle plate 71 is greater than the internal diameter of the internal ring wall 11 of this housing 10 because of the length of its major axis, and this baffle plate 71 can be subject to again driving shaft 40 to control its rotation angle, whereby, this baffle plate 71 can be in the situation that not installing seal arrangement 72, no matter the internal diameter of the internal ring wall 11 of this housing 10 changes to some extent because of rising-heat contracting-cold under the gas of different temperatures or liquid, this baffle plate 71 also can produce rising-heat contracting-cold and change the width of its long axis direction, and the outer periphery 711 that turn to its long axis direction are resisted against the internal ring wall 11 of housing 10 completely, passage 111 is sealed by baffle plate 71, because material high temperature high voltage resistant and the strong acid of baffle plate 71 are examined by force, therefore be applicable to High Temperature High Pressure or strong acid and strong base environment, but when actual use, on baffle plate 71, make sealing effect of the present invention more outstanding with the combination of sealing device 72.
But as described above, it is only preferred embodiment of the present invention, when not limiting scope of the invention process with this, the simple equivalence of generally doing according to the present patent application the scope of the claims and invention description content changes and modifies, and all still remains within the scope of the patent.
