Fig. 3 to Fig. 5 is refer to,
For Fig. 3 to be not added with fluid pressure distribution map during deflector, Fig. 4 is VELOCITY DISTRIBUTION when deflector central angle is 70 degree
Figure, Fig. 5 is pressure profile when deflector central angle is 70 degree.In Fig. 3 and Fig. 5, brighter part represents fluid pressure
Bigger, in Fig. 4, it is faster that brighter part represents rate of flow of fluid.It was found from Fig. 3 to Fig. 5, the pipeline of deflector is additionally arranged except different
Thing device, during whole system normal operation, energy consumption have dropped more than 5 percentage points, and energy-saving effect is obvious.
The present embodiment is described further below.
In a kind of preferred embodiment of the utility model, deflector include the parallel interior plate 21 uniformly arranged, in
Between plate 22 and outer panel 23.Wherein, the original position of deflector is located at the porch of right-angle elbow pipe 1 to the flow direction of liquid
On position after deflection certain angle.As shown in figure 1, for example, the original position of intermediate plate 22 for the porch of right-angle elbow pipe 1 to
Liquid flow direction deflection β angles, the original position of interior plate 21 are the porch of right-angle elbow pipe 1 to liquid flow direction deflection γ
Angle.
Preferably, the original position of interior plate 21 and intermediate plate 22 is that the porch of right-angle elbow pipe 1 is inclined to liquid flow direction
Turn 5 degree to 15 degree, the original position of outer panel 23 deflects 0 degree to 5 degree for the porch of right-angle elbow pipe 1 to liquid flow direction.

The porch of pipe 1 deflects 10 degree to liquid flow direction, and the original position of outer panel 23 flows for the porch of right-angle elbow pipe 1 to liquid
Direction deflects 0 degree.
When central angle corresponding to deflector in above-mentioned embodiment is preferably 70 degree, its flow velocity and pressure distribution are the most equal
It is even, each insides of pipes and outside and the speed difference in whole insides of pipes and outside minimum, and low-pressure area area in pipeline
It is smaller, it is unfavorable for the generation of turbulent flow.
The preparation method that deflector is introduced in citing below.
For example, using steel plate thick 3mm, and it is carried out to be stamped and formed out radian.Differed according to the caliber of each pipeline, I
Using different size steel plate.For example, pipe diameter is 300mm, installation radius of curvature is 400mm, then we will choose three
The steel plate that block length differs, every piece of steel plate installation interval are 75mm, because the radian of our every block of steel plate is 70 °, so we
It can calculate and learn that the length of every block of steel plate is
L1=(400+75) × π × 70/360mm
L2=(400+150) × π × 70/360mm
L3=(400+225) × π × 70/360mm
Then the steel plate that production obtains is welded.Deflector can be formed.
Embodiment two

In the present embodiment, filter screen (3) is parabola, and paraboloidal shape is according to formula u=ρ gJ (R2-r2)/4V is fitted；Its
In, U represents speed of the pipe at any point；J is the loss of flood peak and pipe lenth ratio, represents the water conservancy gradient；V glues for power
Coefficient is spent, R is pipe radius, and r is radius corresponding to any point in pipe.When fluid is that constant speed flows, J, V, R, ρ are equal
For constant, therefore, the VELOCITY DISTRIBUTION of fluid in the duct is a parabola, and as r=0, u is maximum, therefore umax=ρ gJR2/
4V。
The filter screen 3 of the present embodiment, the inhibition that the convection body of conventional tube Inner filter net 3 flows in pipeline is eliminated, intercepted
During to foreign object in pipe, 3 one points of filter screen is pooled in the presence of Fluid pressure, reduces foreign matter convection body to the full extent
Inhibition.
Described above is only the embodiment of the application, it is noted that for the ordinary skill of the art
For personnel, the improvement without creative work made on the premise of the application principle is not departed from all is considered as the application's
Protection domain.
