Abstract
The utility model discloses a novel flow regulating device. The novel flow regulating device comprises a central rotating shaft, blades on the rotating shaft and case type bodies which are symmetrically arranged in a bilateral way. Each case type body is composed of a steel plate B, steel plates A respectively welded on the top and the bottom of the steel plate B, and a steel plate C welded on the outer side of the steel plate B. The inner side surface of the steel plate B is an arc-shaped recessed surface. An arc-shaped plate is welded on the recessed surface. A stop block is welded on the central part of the arc-shaped plate. Flow channel boundaries are arranged over the steel plate A located on the top of the steel plate B and under the steel plate A located on the bottom of the steel plate B. By adopting the arc-shaped plates as the boundary steel plates cooperating with the blades to regulate the flow, the novel flow regulating device prevents a drastic change in the flow channel area during a flow regulating process and achieves smooth flow regulation in a whole-course angle range. The novel flow regulating device which can precisely control flows has stable regulation effects. Meanwhile, the novel flow regulating device has the advantages of simple processing, simple manufacture, relatively low processing cost and greater running reliability.
Description
Technical field
The utility model relates to the flow regulator technical field, particularly a kind of Novel flow rate regulating device.
Background technology
The essence of flow regulation is regulated this device inlet outlet pressure differential exactly, if the Small-angle Rotation of blade causes the larger variation of pressure reduction, can cause the out of true of flow to be regulated, and even can not reach the effect of flow regulation.
Current flow regulator on the market, generally adopt straight flange circle, and blade rotation angle and flow regulation range can not reasonable distribution.Open the initial stage of fluid passage at blade, the subtle change of angle will cause the very big fluctuation of flow, is subject to small external cause and disturbs, and regulating effect is poor.
The utility model content
Goal of the invention of the present utility model is: for the problem of above-mentioned existence, provide a kind of novel flow regulator, more effectively accurate flow adjustment.
The technical solution adopted in the utility model is such: a kind of Novel flow rate regulating device, rotating shaft, the blade in rotating shaft and medianly zygomorphic box body in the middle of comprising, every part box body is comprised of steel plate B, the steel plate A that is welded on steel plate B top and bottom, the steel plate C that is welded on the steel plate B outside, described steel plate B medial surface is arc-shaped concave, weld arc on concave surface, arc middle part welding block is the border, fluid passage below the steel plate A of above the steel plate A at described steel plate B top and bottom.
As preferably, on the arc of described left and right, stagger up and down in the position of block, and the length of described blade is greater than the radius that the arc radius deducts the difference of block length and is less than arc.So both can guarantee to close tight realization and turn-off, also can realize flow area with rotational angle can acute variation with level and smooth regulating flow.
As preferably, offer some air vents on described steel plate C, discharge internal gas because of expanded by heating or the cooling pressure caused.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are: with blade, coordinate the border steel plate of adjust flux to adopt arc, when adjust flux, fluid passage area can sharply not change, can realize that the flow of omnidistance angular range regulates gently, can accurately control flow, regulating effect is stable; Simultaneously, processing and manufacturing is simple, and processing cost is relatively low, moves also more reliable.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in figure: 1 is steel plate A, and 2 is arc, and 3 is block, and 4 is steel plate B, and 5 is steel plate C, and 6 is rotating shaft, and 7 is blade, and 8 is the border, fluid passage.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
Most preferred embodiment: as shown in Figure 1, a kind of Novel flow rate regulating device, rotating shaft 6, the blade 7 in rotating shaft 6 and medianly zygomorphic box body in the middle of comprising, every part box body is comprised of steel plate B 4, the steel plate A 1 that is welded on steel plate B 4 tops and bottom, the steel plate C 5 that is welded on steel plate B 4 outsides.
Described steel plate B 4 medial surfaces are arc-shaped concave, welding arc 2 on concave surface, arc 2 middle part welding blocks 3, on the arc 2 of described left and right, stagger up and down in the position of block 3, and the length of described blade 7 is greater than the radius that arc 2 radiuses deduct the difference of block 3 length and are less than arc 2.
The steel plate A 1 of above the steel plate A 1 at described steel plate B 4 tops and bottom is following is border, fluid passage 8.
Offer some air vents on described steel plate C 5.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
