【Specific implementation mode】
Technical solution of the present invention is clearly and completely described below in conjunction with embodiment, it is clear that described implementation
Example is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, the common skill in this field
All other embodiment that art personnel are obtained without creative efforts should all belong to the model that the present invention protects
It encloses.
Referring to Fig. 1-1 and Fig. 1-2, the slide sheet type pressure energy exchanger of slide plate of the invention and molded line matched design, including
Cylinder body 9, rotor 8 and slide plate 3, rotor 8 are placed in the inner cavity of cylinder body 9, and rotor 8 uses class ellipse using round molded line, cylinder body 9
Inner cavity is divided into fluid A chambers 7 and fluid B chambers 4 by line, rotor 8, and sliding slot 2 is radially provided on rotor 8, is arranged in sliding slot 2
There is slide plate 3.
Referring to Fig. 2, the cylinder shaped conductor 16 of the sides fluid A and the sides fluid B is symmetrical, by seal section I11, entrance 12,
Interlude 13, outlet flow section 14 and seal section II15 are connected in sequence.The entrance 12 and outlet flow section 14 of the sides fluid A respectively with stream

Mouth 5 is pressed into fluid B high-pressure outlets 1 to be connected.
Cylinder shaped conductor 16 carries out matched design with 3 quantity of slide plate, and 13 institute of interlude of cylinder shaped conductor 16 is across angle and slide plate 3
The product of quantity is 2 π.The reasons why structure is arranged is as follows：When the interlude 13 of chamber does not have slide plate 3, such as double slide sheet type knots
When structure slide plate 3 is located at both ends seal section, high-pressure side and low-pressure side are directly connected in chamber, and fluid similar " short circuit " is directly from height
Press effluent to low-pressure side.At this point, in fluid A chambers, high-pressure fluid A is not carried out the output of pressure energy due to being directly connected.
Reverse flow occurs for fluid B chambers, fluid B.When the interlude 13 of the sides fluid A or the sides fluid B exist simultaneously two or two with
When upper slide plate 3, the vessel between two neighboring slide plate 3 is when by major diameter, volume first increases and then decreases.Hold intracavity liquid
Pressure is first depressured rapidly with the increase in space, or even generates cavitation phenomenon, leads to the loss of fluid energy.When space reduces
When, because liquid is approximate incompressibility fluid, the steady running of equipment can be influenced or destroy equipment normal configuration.Three slide sheet types
Angle between the two neighboring slide plate of structure 3 is π/3, can design 13 institute of chamber interlude across azimuthal angle be about π/3,
Have always in the interlude 13 of the sides fluid A and the sides fluid B and only there are one slide plates 3.The structure of three 3 or more slide plates, it may appear that
The case where more than one slide plate 3 is existed simultaneously in interlude 13.It is similar, when 13 institute of interlude is when angle is π/4, slide plate 3
Fair amount be 4, and so on, the condition that 3 quantity of rational slide plate should meet is：3 quantity of slide plate and 13 institute of interlude
Across angle product be π/4.Referring to Fig. 1-1,13 institute of interlude is π/3 across angle, and 3 quantitative design of slide plate is 3；Referring to Fig. 1-
2,13 institute of interlude is π/4 across angle, and 3 quantitative design of slide plate is 4.The structure is arranged, can be effectively reduced pressure energy and be transmitted
Energy loss in journey ensures the stable and high effective operation of equipment.
The seal section I11 and seal section II15 of cylinder shaped conductor 16 are round molded line, and entrance 12 and outlet flow section 14 are seven times
Polynomial curve, interlude 13 are simple harmonic quantity molded line, it is ensured that 16 3 rank of cylinder shaped conductor is continuous, and 16 transition of cylinder shaped conductor is smooth, makes
Force-bearing situation is good when slide plate 3 slides, and reduces mutation power when slide plate 3 slides, reduce the elliptical gear in operation of slide plate 3 and
Motion artifacts.
At seal section I11 and seal section II15, minim gap is set between rotor 8 and cylinder body 9.The setting of seal section is advantageous
In control gap value, extends the leakage path length between two fluids, effectively inhibit blending procedure.
The polar diameter function of cylinder shaped conductor 16For：
Wherein,For azimuthal variations；θ0、θ1、θ2And θ3For azimuth；R1For 16 short radius of cylinder shaped conductor；R2For cylinder
16 major radius of line；a0~a15For the equation coefficient to be asked of above-mentioned equation group, meet following condition：
Special, R1=0.0700m, R2=0.0850mm, θ0=5 °, θ1=30 °, θ2=150 °, θ3=175 °, have：

The operation principle of slide plate of the present invention and the slide sheet type pressure energy exchanger of molded line matched design is：
The pressure energy that the sides fluid A high-pressure fluid contains pushes slide plate 3 that rotor 8 is driven to rotate, and the rotation of rotor 8 drives fluid B
Sideslip piece 3 pushes the fluid in fluid B chambers 4 to enter pressure piping, the pressure energy of high-pressure fluid A is so passed to low pressure
Fluid B realizes high-pressure fluid A supercharging low-pressure fluids B's by the slide sheet type pressure energy exchanger of slide plate and molded line matched design
Process.
It should be noted that the slide sheet type pressure energy exchanger of slide plate disclosed by the invention and molded line matched design, cylinder body
Molded line is connected in sequence by seal section I11, entrance 12, interlude 13, outlet flow section 14 and seal section II15,12 He of entrance
Molded line at outlet flow section 14 is seven curves, it is ensured that three ranks of cylinder shaped conductor 16 are continuous.Similar, when entrance 12 and go out stream
, it can be achieved that the quadravalence of cylinder shaped conductor 16 is continuous when molded line at section 14 is nine curves；At entrance 12 and outlet flow section 14
, it can be achieved that five ranks of cylinder shaped conductor 16 are continuous etc. when molded line is ten curves.Molded line at entrance 12 and outlet flow section 14
Degree of curve is higher, it can be achieved that molded line higher order is continuous, improves the force-bearing situation in 3 motion process of slide plate, to a greater degree
Reduce the elliptical gear and motion artifacts of slide plate 3 in operation.
In conclusion the slide sheet type pressure energy exchanger of slide plate disclosed by the invention and molded line matched design, cylinder shaped conductor
16 and the design of 3 quantity Matching of slide plate, the institute of interlude 13 of 3 quantity of slide plate and cylinder shaped conductor 16 is 2 π across the product of angle, can be subtracted
Vessel between few two neighboring slide plate 3 because space increase cause liquid be depressured rapidly caused by energy loss, avoid because of liquid
Body can not steady running or destruction equipment normal configuration by the equipment caused by compression.Meanwhile in seal section I11 and seal section
At II15, minim gap is set between 9 inner wall of rotor 8 and cylinder body, this is designed with conducive to control gap value, extends between two fluids
Leakage path length, effectively inhibit blending procedure.16 high-order of the cylinder shaped conductor is continuous, and molded line transition is smooth, and slide plate 3 is made to slide
