Abstract

The utility model discloses a reducing flow pipe section, which comprises a straight pipe section and reducers which are arranged at the inlet end and the outlet end of the straight pipe section, and the reducing flow pipe section is characterized in that: a plurality of guiding ribs are uniformly distributed inside the reducer of the inlet end. The guiding ribs and the reducers are integrated onto the flow pipe section, so the high flow speed and the low flow speed of fluid inside the pipe section can be comprehensively rectified.

Description

A kind of undergauge flow pipeline section
Technical field
The utility model relates to flowtube, relates in particular to a kind of undergauge flow pipeline section.
Background technique
As shown in Figure 1, 2, existing undergauge flow pipeline section comprises the undergauge 1 at straight length 2 and two ends thereof.The undergauge 1 of this type of flow pipeline section can realize that the high flow rate of convection cell carries out rectification, but when fluid hanged down flow velocity, undergauge did not have the rectified action to the pipeline section inner fluid, has certain narrow limitation.
The model utility content
For this reason, technical problem to be solved in the utility model provides a kind of undergauge flow pipeline section, the rectification when it can realize pipeline section inner fluid different in flow rate easily, thus play the effect of stabilized fluid state, to overcome the defective that prior art exists.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of undergauge flow pipeline section comprises straight length and the undergauge that is positioned at straight length entrance point and outlet end, and it is characterized in that: the described undergauge that is positioned at entrance point is furnished with some water conservancy diversion ribs.
Further characteristics of the present utility model are that the end that described water conservancy diversion rib caters to fluid is streamlined.Such water conservancy diversion rib convection cell resistance is little, helps fluid and passes through rapidly.
Further characteristics of the present utility model are that described water conservancy diversion rib is evenly spaced apart along the circumferencial direction of undergauge.
Further characteristics of the present utility model are that described undergauge is consistent with the internal diameter and the inside diameter of straight pipe section of straight length connecting part.
Further characteristics of the present utility model are that described undergauge central axis and straight length central axis are on same straight line.
The beneficial effects of the utility model are, described undergauge flow pipeline section is by having increased the water conservancy diversion rib in the undergauge of entrance point, make it except having the rectified action of undergauge to the high flow rate fluid, also have of the rectified action of water conservancy diversion rib to low flow rates of fluid, thereby make the utility model can realize rectified action, thereby play the effect of stabilized fluid state pipeline section inner fluid different in flow rate.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is elaborated:
Fig. 1 is the prior art constructions schematic representation;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is a structural representation of the present utility model;
Fig. 4 is the side view of Fig. 3.
Among the figure: 1-undergauge, 2-straight length, 3-water conservancy diversion rib.
Embodiment
The utility model is the improvement on the undergauge flowtube segment base plinth of prior art.
Shown in Fig. 3,4, undergauge flow pipeline section of the present utility model comprises two undergauges 1 of straight length 2 and straight length entrance point and outlet end, and undergauge 1 is horn-like, and it is small-bore to be connected with straight length 2.Undergauge 1 is consistent with the internal diameter and straight length 2 internal diameters of straight length 2 connecting parts.Undergauge 1 central axis and straight length 2 central axis are on same straight line.
Improvements are for to be furnished with some water conservancy diversion ribs 3 at the undergauge 1 that is positioned at entrance point.In order to reduce the resistance of convection cell, the end that water conservancy diversion rib 3 caters to fluid (direction of arrow is direction of flow) is streamlined.
After having increased water conservancy diversion rib 3 in the entrance point undergauge 1, except undergauge can have the rectified action the high flow rate fluid, the water conservancy diversion rib can also carry out rectification to low flow rates of fluid, thereby the effect of stabilized fluid state is finally played in the rectification when making the utility model can realize pipeline section inner fluid different in flow rate.
