The working principle of the utility model pipe power valve:
When valve opening: as shown in Figure 1, the pressure P1 of the input end 21 of valve body 1 gradually rises after water pump starting, eccentric big valve
Valve 2 is intended to around valve rod center line 26 rotationally clockwise under water jet propulsion, but at this time small flap 3 in 15 medium pressure of upper cavity
Under power P2 effect, eccentric big valve flap 2 is pushed down, its rotation is prevented, valve can not be opened；After import pressure medium P1 is more than valve
When pressure P2,21 pressure water of input end wherein all the way, enters lower chamber 18 through bypass pipe 1 and regulating valve 1, pushes diaphragm
11 uplink of pressing plate 17 and rubber diaphragm drives small flap 3 rotationally clockwise by mandril 7, releases to eccentric big valve flap 2
Constraint, the another way of 21 pressure water of input end push eccentric big valve flap 2 to rotate, and follow small flap 3 closely and slowly open together, complete out
Valve.Meanwhile as shown in figure 3, medium through bypass pipe 28, regulating valve 29 flows back to 1 outlet end 23 of valve body in upper cavity 15；Pass through tune
The speed that valve 29 adjusts 15 medium back flow of upper cavity is saved, opening time and the opening speed of eccentric big valve flap 2 can be controlled.
When closing valve: when termination of pumping or forced outage, as shown in figure 4,1 input end of valve body, 21 pressure P1 is quickly reduced, water flow velocity
When degree is close to " 0 ", for eccentric big valve flap 2 under the effect of self gravity square, most reflux medium is truncated in quick closedown；This
When, 23 pressure P2 of outlet end is far longer than 21 pressure P1 of input end, and 23 medium of outlet end is quick through bypass pipe 28, regulating valve 29
Into upper cavity 15,11 downlink of rubber diaphragm is pushed, small 3 slowly closing of flap is driven by mandril 7；Final pipe power valve closes completely
It closes (at this point, i.e. state shown in Fig. 1).Meanwhile the medium of lower chamber 18 through bypass pipe 1, regulating valve 1 flow back to valve body 1 into
Mouth end 21；The closing velocity of small flap 3 can be controlled by regulating valve.During small 3 slowly closing of flap, discharge orifice 28
It lets out except a small amount of recirculation water, to cut down water hammer pressure peak value.According to water hammer time of return, the closing of the small flap 3 of Field adjustment
Time, it is ensured that water hammer surge pressure prevents water hammer accident, it is ensured that pipe network equipment no more than 1.2 times of design engineering pressure
Safety.
For apparent definition each parameter of lower curve 5-8, as shown in figure 5, the invention also discloses institutes
The method for drafting of lower curve 5-8 is stated, specifically includes the following steps:
Step 1 with valve rod center line 26 is the center of circle, with the horizontal distance between mandril center line 24 and valve rod center line 26
L1 is that radius draws circle, obtains basic circle 5-12；Central coordinate of circle is set as (0,0), then the curvilinear equation of basic circle 5-12 is X2+Y2=D2
Wherein X: the horizontal coordinate value at any point on basic circle, Y: the vertical coordinate value at any point on basic circle, D: basic circle
Diameter；
Step 2, by the left intersection point 5-4 of the circular arc of the basic circle 5-12 and the basic circle 5-12 horizontal center line, make
For the starting point of lower curve 5-8, if draw lower curve 5-8 on intersection point 5-2 in addition to starting point, first in the basic circle 5-12
Take up an official post and take a bit, be named point A5-10, the coordinate of the point A5-10 is X=1/2DcosA, Y=1/2DsinA, then the excessively described point
A5-10 is the vertical line 5-9 (normal of the i.e. described intersection point 5-2 of the vertical line 5-9) of radius 5-11, cuts on the vertical line 5-9
Taking length is the line segment of L, obtains the tangent line 5-3 for making the excessively described intersection point 5-2 of intersection point 5-2(be intersection point 5-2 on lower curve 5-8, institute
The tangent line 5-3 for stating intersection point 5-2 is vertical with normal)；The included angle A refers to the basic circle 5-12 horizontal center line and crosses point
The angle between radius 5-11 that A5-10 is done, 0 °≤included angle A≤90 °；
The length L is the corresponding arc length of included angle A, length L=π DA/360 °；Wherein D are as follows: the basic circle
The diameter of 5-12, wherein A for the basic circle 5-12 horizontal center line and crosses the folder between the radius 5-11 that point A5-10 is done
Angle:
When point A5-10 is located at the bottom of the basic circle 5-12, at this point, when included angle A is 90 degree, resulting intersection point 5-2
The terminal 5-13 of the as described lower curve 5-8；
Step 3 chooses multiple arbitrary points on the basic circle 5-12, can successively obtain the friendship on multiple lower curve 5-8
Resulting multiple intersection point 5-2 are connected with fair line, can draw out lower curve 5-8, the curve of the lower curve 5-8 by point 5-2
Equation is x=1/2 × D × (cosA+AsinA), y=1/2 × D × (sinA-A × cosA), z=0；Wherein, D is the basic circle
The diameter of 5-12, the horizontal center line and cross the angle between the radius 5-11 that point A5-10 is done that A is the basic circle 5-12,
Unit is radian.
Further, when step 2 chooses arbitrary point point A, the basic circle 5-12 can be divided into 36 equal portions, choose equal part
Point is point A, more convenient for calculating and drawing.
The working principle of the utility model hyperbola sliding slot 5:
Intersection point 5- when small flap crank 4 is rotated clockwise around the valve rod center line 26, i.e., on the described lower curve 5-8
2 around the valve rod center line 26 rotationally clockwise when, as shown in fig. 6, the normal of the intersection point 5-2 and the mandril center
Line 24 is overlapped, and the tangent line 5-3 of the intersection point 5-2 is overlapped with the horizontal center line of the basic circle 5-12, at this point, lower curve 5-8
There was only the thrust of vertical direction to pin shaft 6, the not no thrust of horizontal direction, because without making mandril 7 occur bending and deformation, thus
So that mandril 7, when moving up and down, diaphragm seat centre bore 22 and valve body axis hole 25 will not card resistance mandrils 7；And when rotational angle is
At 90 degree, as shown in fig. 7, the small flap 3 turns to extreme higher position, pipe power valve standard-sized sheet.
Embodiment described above is only the preferred embodiment of the utility model, and the not feasible implementation of the utility model
Exhaustion.For persons skilled in the art, it is made under the premise of without departing substantially from the utility model principle and spirit
Any obvious change out, should all be contemplated as falling within the claims of the utility model.
