Embodiment
Below, in conjunction with the accompanying drawings the specific embodiment of the present invention is described.
As Fig. 1-shown in Figure 4, adjustable orifice plate device of the present invention comprises: throttle orifice flange 10, no throttle orifice flange 20, restricting orifice 30 are arranged; In addition, although not shown, described adjustable orifice plate device also includes packing ring, screw bolt and nut etc.
As shown in Figure 1, described have throttle orifice flange 10 to be provided with the throttle flap 11 that reduces flow area in inside, thereby on plane, described throttle flap 11 place, formed first through flow hole 14, have the outer wall of throttle orifice flange 10 radially to convex with first flange 12 described, described first flange 12 is provided with at least two first through hole 13 that connects vertically.
As shown in Figure 2, described no throttle orifice flange 20 radially convexes with second flange 22 at outer wall, and described second flange 22 is provided with at least two second through hole 23 that connects vertically.
Described restricting orifice 30 is assemblied in describedly to be had between throttle orifice flange 10 and the described no throttle orifice flange 20.And, as shown in Figure 3 and Figure 4, be provided with second through flow hole 34 littler in the described restricting orifice 30 than the flow area of described no throttle orifice flange 20.
Described packing ring is arranged on described restricting orifice 30 both sides, describedly has between throttle orifice flange 10 and the described no throttle orifice flange 20.
Described bolt passes corresponding described first through hole 13 and described second through hole 23 and cooperates with described nut, describedly has throttle orifice flange 10 to fixedly connected with described no throttle orifice flange 20 thereby make.
Preferably, the shape of described first through flow hole 14 and size are identical with second through flow hole 34.
And, as Fig. 3 and shown in Figure 5, the shape of described first through flow hole 14 and described second through flow hole 34 be two with footpath circle behind two centers of circle skew predetermined distance the shape of overlapping part.
In this case, as shown in Figure 5, when described first through flow hole 14 overlaps with second through flow hole 34, the through-current capacity maximum of described adjustable orifice plate device; In contrast to this, in described first through flow hole 14 and second through flow hole 34 one during with respect to position shown in Figure 5 (in plane shown in Figure 5) Rotate 180 °, the through-current capacity of described adjustable orifice plate device becomes minimum.
