Description

Adjustable orifice plate device
Technical field
The utility model relates to the restricting orifice device that is used to adjust flow in the pipeline, particularly a kind of adjustable orifice plate device of being convenient to regulate flow.
Background technique
Usually be provided with restricting orifice on the process pipe, to be used to regulate flow.Traditional restricting orifice area is certain, unadjustable, that is, existing restricting orifice is fixed.This restricting orifice has following shortcoming:
Orifice size is fixed, and is unadjustable;
Flow when requiring not satisfying fluid, need the system relevant that stop transport, orifice plate is pulled down, and be machined to suitable area with this pipeline;
If flow area need reduce, the restricting orifice that need more renew then;
The model utility content
Therefore, in order to address the above problem, the utility model proposes a kind of adjustable orifice plate device, it comprises: throttle orifice flange, no throttle orifice flange, restricting orifice, packing ring, screw bolt and nut are arranged;
Described have the throttle orifice flange to be provided with the throttle flap that reduces flow area in inside, thereby on plane, described throttle flap place, formed first through flow hole, have the outer wall of throttle orifice flange radially to convex with first flange described, described first flange is provided with at least two first through hole that connects vertically;
Described no throttle orifice flange radially convexes with second flange at outer wall, and described second flange is provided with at least two second through hole that connects vertically;
Described restricting orifice is assemblied in describedly to be had between throttle orifice flange and the described no throttle orifice flange, and is provided with second through flow hole littler than the flow area of described no throttle orifice flange in the described restricting orifice;
Described packing ring is arranged on described restricting orifice both sides, describedly has between throttle orifice flange and the described no throttle orifice flange;
Described bolt passes corresponding described first through hole and described second through hole and cooperates with described nut, describedly has the throttle orifice flange to fixedly connected with described no throttle orifice flange thereby make.
Preferably, the shape of described first through flow hole and size are identical with second through flow hole.
Preferably, described first through flow hole and described second through flow hole be shaped as two with footpath circle behind two centers of circle skew predetermined distance the shape of overlapping part.
Preferably, described first through hole and described second through hole are evenly arranged on peripheral direction accordingly.
Adjustable orifice plate device of the present utility model has the following advantages: area is regulated than big; Can realize flow area by little to greatly or adjusting from large to small; Can satisfy different traffic requirements.

Embodiment
Below, in conjunction with the accompanying drawings embodiment of the present utility model is described.
As Fig. 1-shown in Figure 4, adjustable orifice plate device of the present utility model 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.
And preferably, described first through hole 13 and described second through hole 23 are evenly arranged on peripheral direction accordingly.
To sum up, adjustable orifice plate device of the present utility model has the following advantages: area is regulated ratio Greatly; Can realize flow area from small to large or adjusting from large to small; Can satisfy different flows Requirement.
