For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of anti-sand setting mud flow rate measuring flume comprises cell body, is provided with outlet and entrance on the cell body, it is characterized in that: be provided with the baffle plate that can regulate height on the runner of described cell body, baffle plate is provided with opening, and the entrance height of cell body is higher than open height.
Described cell body bottom surface and horizontal plane angle are between 9-12 degree.
The throat width of described cell body is greater than exit width, and the ratio of throat width and exit width is between 1/4-1/2.
It is triangle that described baffle plate and cell body form top, and the middle part is rectangle, and the bottom is the throttling cross section of equilateral inverted trapezoidal.
The opening of described baffle plate is inverted V-shaped, and V-shaped part and cell body outlet are in the same way.
Be provided with the scale value of indication baffle plate setting height(from bottom) on the described baffle plate.
Employing the utility model has the advantage of:
One, in the utility model, be provided with the baffle plate that to regulate height on the runner of described cell body, by the controllable register setting height(from bottom), can change the throttleng surface area, enlarged the mud flow rate measurement category, baffle plate is provided with opening, and the entrance height on the cell body is higher than open height, the low structure of the high outlet of entrance increases slurry flows flow velocity when cell body, prop-carrying capacity strengthens, and prevents from forming sand setting in the measuring flume, adopts this structure can prevent sand setting in measuring flume, flow measurement range is wide, satisfies the instructions for use of measuring mud flow rate.
Two, in the utility model, described cell body bottom surface and horizontal plane angle are between 9-12 degree, and this structure not only makes slurry flows flow velocity when cell body increase, and makes the prop-carrying capacity of cell body reach best.
Three, in the utility model, the throat width of described cell body is greater than exit width, and the ratio of throat width and exit width further makes slurry flows flow velocity when cell body increase between 1/4-1/2, improves prop-carrying capacity.
Four, in the utility model, it is triangle that described baffle plate and cell body form top, and the middle part is rectangle, the bottom is the throttling cross section of equilateral inverted trapezoidal, the throttling cross section of this structure can make the fluid level of the cell body of flowing through comparatively fast be elevated to desired locations, can make again liquid level more stable.
Five, in the utility model, the opening of described baffle plate is inverted V-shaped, and V-shaped part and cell body outlet are adopted this structure in the same way, are convenient to the adjusting joint flow area, have further enlarged the mud flow rate measurement category.
Six, in the utility model, be provided with the scale value of indication baffle plate setting height(from bottom) on the described baffle plate, this scale value can be reacted crest of weir baffle plate setting height(from bottom), again convenient highly adjusting.
